The Town would apply annually to NYSDEC for Deer Damage Permits(DDP)-also known as nuisance permits-to reduce the deer numbers. This approach is not considered regular hunting and the Town program proposes to use archers(including crossbows)at baited locations. Firearms could also be used at selected sites in the rural and agricultural areas of the Town. All healthy deer venison culled will either be consumed by the participants and landowners,or donated through the Venison Donation Coalition Inc. See attached"Town of Ithaca-Deer Management Program Proposal"for detailed information about the program.

Part 3 should also explain how the lead agency determined that the impact may or will not be significant.Each potential impact should be assessed considering its setting, probability of occurring,duration,irreversibility,geographic scope and magnitude. Also consider the potential for short- term,long-term and cumulative impacts. There are no anticipated negative environmental impacts related to the proposed deer management program. As outlined in the May 2017 report (Deer Management: Recommended Actions for the Town of Ithaca)from the Town of Ithaca Conservation Board, the Town is proposing to address the overpopulation of deer by pursuing a culling program. The Town program would apply to NYS Department of Environmental Conservation for Deer Damage Permits (DDP)and use proficient volunteer archers (firearms could also be used at select sites in the rural and agricultural areas of the Town)at baited locations. Locations for the baited sites will be scattered throughout the Town, and could include residential properties, cemeteries, farms, and in natural areas. Detailed information about the proposed program can be found in the attached document titled "Town of Ithaca - Deer Management Program Proposal". The existing overpopulation of deer are creating a significant ecological impact (deer forage of native vegetation, little forest regeneration), health and human safety issues (ticks/Lyme disease), agricultural losses (crop damage, diseases and parasites transmitted to animals), and vehicle/deer collisions. Deer overpopulation is a product of the ideal food and shelter offered by the urban and suburban landscape, inadequate predation pressure, and protection from hunting in some areas. Deer management efforts by adjacent municipalities and Cornell University have made modest gains towards their goals, but the addition of a similar program in the Town would enhance their efforts. Based on the experience of Cornell and other local municipalities, deer management programs are safe, and support public health and the environment. All healthy deer venison culled will either be consumed by the participants or donated through the Venison Donation Coalition Inc. While the program may operate with locations in a CEA, in or near wetlands, streams or floodplains, or in or near areas containing threatened or endangered species, the program will not alter or damage any of these resources and the reduction in deer numbers should benefit these resources. Check this box if you have determined,based on the information and analysis above,and any supporting documentation, that the proposed action may result in one or more potentially large or significant adverse impacts and an environmental impact statement is required.

This report outlined the history and justification of deer management (health and human safety, ecological, agricultural losses, car-deer collisions, NYSDEC Deer Management Focus Area), a review of local deer management programs in Tompkins County (Village of Trumansburg, Cornell University, Village of Cayuga Heights, Village of Lansing), and provided recommendations for a potential Town of Ithaca deer management program (form sub-committee, utilize NYSDEC Deer Damage Permits for a Town program, measure impacts of deer to assess effectiveness of program, coordinate efforts with adjacent municipalities and Cornell University, etc.). The Ithaca Town Board reviewed and discussed this report and in September 2017, formally established a Deer Management Committee. This Committee met several times in the spring and summer of 2018 and held a public meeting in May 2018 seeking feedback on the report and the potential of a deer management program. The public feedback received was very positive regarding deer management in the Town and the Town Board agreed to move forward with establishing a program. The Town Board designated $4,000 in the 2019 Town budget for this program. Based on input from the Town's Conservation Board, the Town's former Deer Management Committee, representatives from Cornell University and other local municipal deer management programs, and the new Town Deer Management Oversight Committee, the use of New York State Department of Environmental Conservation (NYSDEC) approved Deer Damage Permits (DDP) — also known as nuisance permits — is recommended to reduce deer numbers. This approach is not considered regular hunting and for the Town of Ithaca program it proposes to use proficient archers (including crossbows) at baited locations as the preferred low cost method. Firearms could also be used at selected sites in the rural and agricultural areas of the Town. What follows is believed to be the best approach to significantly reduce the deer population and negative impacts of the high deer level in the Town of Ithaca. It is anticipated that for this initial year, 10 or less properties will be used. The Town program, once fully implemented, is designed to initially reduce the size of the deer population over the first few years, and then provide stability in population numbers thereafter. It is proposed (pending DEC approval) that implementation of the deer management program will start on February 1, 2019 and continue until March 31, 2019 at the latest. Once the final list of sites is determined, a map showing the locations will be available at Town Hall and will be posted on the Town of Ithaca's website (http://www.town.ithaca.ny.us/Deer). The Deer Management Oversight Committee will continue to review properties across the Town that are ideal locations given their size, expected deer traffic, and availability of trees and cover for this first year. The following is detailed information on the Town of Ithaca deer management program. 1. Activities are proposed to occur from February 1, 2019 to March 31, 2019. The Town's Deer Management Oversight Committee will review the success of the program and will reduce or 1 January 16,2019 expand activities as needed based on deer harvests and assessment on ecological and other indicators. All landowners will be kept informed about management activities (including who the participants are on their property) in regular updates. 2. Tree stands will be placed (no screw insteps, ladder stands are preferred) at landowner approved locations prior to February 1St. A few branches may need to be trimmed to improve shooting lanes. Shooting from elevated positions directs arrows/bullets into the ground after passing through a deer. Trail monitoring cameras may be installed to capture deer activity. If needed, locations may need to be shifted slightly or abandoned. Each landowner will be informed about any activities on their properties, as indicated by landowner preferences. If an elevated position cannot be used and the area is found to hold deer, the use of a ground blind can be implemented. 3. The Town would seek a small group of proficient participants. Participants will be selected and approved by the Deer Management Oversight Committee. A demonstration of archery or firearm marksmanship may be required. A background check through the Tompkins County Sherriff's Department may also be required. Participants will primarily be using compound bows or cross bows, but could potentially use a firearm in selected locations in the rural and agricultural areas of the Town. The activities are coordinated by Michael Smith, Senior Planner, Town of Ithaca, and he is assisted by members of the Town of Ithaca Deer Management Oversight Committee. 4. Activities will occur as needed to allow for variations in weather conditions, deer movement patterns and participants' availability. There will be the use of supplemental lights after dark that will allow for safe, highly accurate shots at very close range. All of the participants are experienced in using this approach and any new ones will be trained. Deer use patterns at bait will be monitored using infrared trail cameras to target the best possible times to utilize locations. 5. All participants are required to follow all Town rules and laws, NYS laws, and any expressed landowner preferences. It is the right of each landowner, if so desired, to select individuals among approved participants who may be permitted access to their property, the times or dates participants are allowed on properties, stand locations, parking locations, or access routes as desired. The agreement to use properties can be terminated by landowners at any time by notifying Michael Smith, Senior Planner,Town of Ithaca (msmith@town.ithaca.ny.us). 6. Which days and stands will be used cannot be predicted in advance, as this will depend on individual time schedules, wind direction, weather, and previous use of stand locations. To prevent overuse, the use of resting periods of 1-2 weeks between activity periods will allow deer to fall back into their usual use patterns. Baiting will continue during the resting periods. 7. Participants will be in trees using camouflage and will use flashlights to locate shot deer or to walk in or out of the woods; therefore landowners may notice a slow moving flashlight. If deer can't be readily retrieved due to poor blood trails, approved tracking dogs are available to help in locating the wounded deer. In very rare circumstances, tracking may occur the next morning with better light. Landowners will be alerted to any of these possibilities and will have access to cell phone numbers of participants. 2 January 16,2019 8. Occasionally a mortally wounded deer may run beyond property boundaries. All participants will have information about property boundaries when in the field. This information will include phone numbers of landowners and neighbors who need to be notified if a search extends beyond the approved properties. If necessary, the participant or member of the Deer Management Oversight Committee will call and ask permission to retrieve a deer, unless pre- authorization to retrieve deer from a property exists. An attempt will be made to inform all immediate neighbors on these activities, regardless of whether a deer ever leaves an approved property. 9. Participants will keep track of and report all shots (arrows/bullets) using a secure website (Qualtrics website). Arrows usually pass through deer and fall close to the spot where a deer was hit, but occasionally will remain in the deer. Every effort will be made to retrieve arrows (they are expensive), aided with the help of a metal detector when needed. 10. All shot deer will be removed discretely and not be field dressed on properties, unless previously approved by the landowner. 11. All harvested deer will be consumed by participants, landowners, or donated. As many deer as possible will be dropped off to an approved venison donation processor for distribution to local food banks and pantries for families that can benefit from the meat. 12. In most instances, landowners and neighbors will not notice activities or the killing of a deer, since it happens fast. However, despite all precautions and skills, deer may be wounded, may not expire immediately, collapse on neighboring properties or may not be found. Every effort will be made (including the use of a trained dog) to recover all animals or assure that they will be fine (superficial arrow wounds heal quickly). 13. The Town Deer Management Oversight Committee will review activities and success in regular intervals and determine if activities should continue or be terminated based on activities and number of deer harvested. 14. The Deer Management Oversight Committee will provide regular updates to the Town Board, including the number of deer harvested, which will also be posted on the Town's website (http://www.town.ithaca.ny.us/Deer). 15. The goal of the program is to reduce deer numbers to levels where forest regeneration and survival of browse sensitive plants within the Town of Ithaca is once again possible. In addition, the program seeks to reduce deer tick populations to levels where Lyme disease risks are minimized, reduce vehicle collusions with deer, and reduce agricultural crop damage. With assistance from the Town of Ithaca Conservation Board, the ecological success of deer reductions in the Town may be assessed using oak sentinels or other plants. 16. Given the high deer densities and the articulated ecological and health goals, the program will aim to target both antlered and antlerless deer. This requires approval by the NYSDEC. Participants shooting bucks will be required to saw off antlers and antlers will be delivered to the NYSDEC by the Town. 3 January 16,2019 Town of Ithaca Contacts: William Goodman,Town Supervisor Email: bgoodman@town.ithaca.ny.us Office Phone: 607-273-1721 Cell Phone: 607-229-8142 Michael Smith, Senior Planner Email: msmith@town.ithaca.ny.us Office Phone: 607-273-1747(ext. 123) 4 NEWlf"ORK Department of New York State Department of Environmental Conservation STATE PPORT F OPPi]FETUNJI1fX Environmental Division of Fish and Wildlife Conservation.

The public feedback received was very positive regarding deer management in the Town and the Town Board agreed to move forward with establishing a program. The Town Board designated $4,000 in the 2019 Town budget for this program. The Town of Ithaca is proposing to address the overpopulation of deer by pursuing a culling program. The Town program would use proficient volunteer archers (firearms could also be used at select sites in the rural and agricultural areas of the Town) at baited locations. Locations for the baited sites will be scattered throughout the Town, and could include residential properties, cemeteries, farms, and in natural areas. The Town has obtained interest from seven landowners to host bait locations on their property for the initial 2019 program. Five of the landowners have stated that they already have hunters on their property, and that they want those individuals they know to be the participant on their property. The proposed Town program, once fully implemented, is designed to initially reduce the size of the deer population over the first few years, and then provide stability in population numbers thereafter. Detailed information about the proposed program can be found in the attached document titled "Town of Ithaca - Deer Management Program Proposal". The existing overpopulation of deer in the Town are creating a significant ecological impact (deer forage of native vegetation, little forest regeneration), health and human safety issues (ticks / Lyme disease), agricultural losses (crop damage, diseases and parasites transmitted to animals), ornamental landscape damage, and vehicle/deer collisions (see attached map showing "Vehicle Collisions with Deer") as further described below. • Ecological Impact— Deer suppress not only the perennial herbaceous layer of the forest through grazing the understory, they also alter the succession trajectories of forests via browsing. Native plants, including tree species, are disappearing from the Town landscape only to be replaced by unpalatable non-native and invasive plants. In a series of 2017 ecological assessments for the Town of Ithaca parks and preserves, Newleaf Environmental LLC consistently documented that tree regeneration is very low (less than 100 seedlings per acre) with heavy deer pressure and competition from invasive shrubs impeding young tree growth. The photo below is from the 1 January 10,2019 Finger Lakes Land Trust's Sweedler Preserve at Lick Brook (located in the Town of Ithaca on Townline Rd) taken in 2017 of a deer exclosure they have been maintaining for several years. �r o. a • Health and Human Safety Issues— Deer serve as the primary host for the adult blacklegged tick, the vector for Lyme disease. In a pivotal Connecticut study, the rates of Lyme disease in a community were tracked over 13 years in conjunction with the implementation of a deer management program. There was a strong correlation between deer population reduction and decreased incidence of the disease. In Tompkins County, the incidence of Lyme disease has increased by 50% since 2011. The Town of Ithaca has posted signs at the entrances to most the Town parks and trails as a warning about the possibility that ticks are present and how to avoid them. • Agricultural Losses —The Town of Ithaca contains approximately 3,412 acres of active farmland associated with approximately 25 farms. The 25 farms in the town represent a diversity of enterprises ranging from small-scale fruit and vegetable producers, livestock farms, and ornamental horticultural businesses to a few farmers engaged in larger-scale dairy and commodity field-crop production. In early 2018, the Town asked farmers about their experiences with deer through email and at Town Agricultural Committee meetings, with all of the responses (including seven email responses) experiencing some level of damage to their crops (fruit trees, vegetables, nursery plants, field crops, etc.) and expenses related to deer. Town farms that raise sheep and goats are especially impacted by deer, since they are vector for barber pole worm. The equestrian operations in the Town are concerned with tick-borne viruses, which affect their horses and can very costly to diagnose and treat. The farms that contain fruit trees, vegetables and nursery stock have resorted to installing 8 foot tall deer fencing around large areas or tree guards around individual trees. • Ornamental Landscape Damage — In the residential and higher density areas of the Town, the overpopulation of deer are negatively impacting the ornamental landscapes and gardens at residences, business, college campuses and cemeteries. The deer are causing damage by heavy browsing and rubbing their antlers on ornamentals throughout the year. Since there is limited opportunity for regular hunting in these high density areas, there are limited options to eliminating deer in these areas. Some private landowners have installed fencing or used repellents, but that is only helpful for those individual properties. 2 January 10,2019 • Vehicle / Deer Collisions—According to data obtained from the Ithaca Tompkins Transportation Council (crash data from NYSDOT Accident Location Information System) for the years 2012 through 2016, 439 accidents involved deer in the Town of Ithaca. This database utilizes all crashes reported to the Department of Motor Vehicles. The attached map, "Vehicle Collisions with Deer— 2012 — 2016", shows the approximate location of any accidents that involved deer and is broken down by each year. While some deer hunting is occurring in the rural and agricultural areas of the Town and there is the Tompkins County Deer Management Focus Area hunting available throughout the Town, the issues above are still occurring. Deer management efforts by adjacent municipalities (Villages of Lansing and Cayuga Heights) and Cornell University have made some gains towards their goals, but the addition of a similar program in the Town would enhance their efforts. We respectfully request approval of the Town of Ithaca's DDP application, starting as early as possible after February 1, 2019 and continuing to March 31, 2019. We request the ability to take deer of either sex (with any antlers delivered to the NYSDEC every 10 days), using archery, crossbows or firearms, with shooting over bait during a 24 hour period. The specific parcels where activity will occur are shown on the attached map ("NYSDEC Deer Damage Permit Application — Parcels where Activities will Occur", dated January 14, 2019).

Introduction The South Hill water system is located in the south portion of the Town of Ithaca, NY and represents only a portion of the Town's overall water system. The system supplies a total of 958 water services and has an average daily demand of 650,000 gallons per day (gpd). The system is supplied from the Southern Cayuga Lake Intermunicipal Water Commission (SCLIWC) transmission main from the Pearsall Place control valve/pressure reducing valve (CV/PRV) connection. The South Hill water system consists of three water service zones: North view/Danby, Troy Road, and Ridgecrest. The Northview/Danby service zone has two water storage tanks and the Troy Road and Ridgecrest service zones each have one tank. The Danby Road, Northview, Troy Road, and Ridgecrest water storage tanks were constructed in 2013, 2012, 1991, and 1968, respectively. The West Hill water system is located in the west portion of the Town of Ithaca, NY and also represents only a portion of the Town's overall water system. The system supplies a total of 537 water services and has an average daily demand of 260,000 gpd. The system is supplied from the South Hill water system through the Stone Quarry CV/PRV connection. The West Hill water system consists of three water service zones: Bostwick Road, West Hill, and Trumansburg Road, each with one water storage tank. The Bostwick Road, West Hill, and Trumansburg Road water storage tanks were constructed in 2001, 2003, and 2016, respectively. The Town desires an analysis of the existing South and West Hill water systems using hydraulic models so they can plan improvements as part of the Town's Capital Improvement Program. 1.1 Purpose For the study, separate computer-based hydraulic models were developed and calibrated to perform a hydraulic analysis of the South Hill and West Hill water systems to determine their performance under varying demand conditions and fire flow conditions. The hydraulic analysis assisted in evaluating the adequacy of the existing water storage tanks, locating aging facilities, and determining the adequacy of the distribution system under existing and future conditions with estimated additional development. The models were used to identify ways to improve system pressures and increase fire flow. They also identified and evaluated potential improvements to the water systems which would correct system deficiencies, increase capacity for future development, and address aging facilities. 1.2 Scope of Services GHD Consulting Services Inc. was retained to develop computer-based hydraulic models and capital improvement alternatives for the South Hill and West Hill water systems. The models were used to evaluate the existing water storage tanks and overall system hydraulic capacity under existing conditions; evaluate water storage and hydraulic capacity under future conditions; assess system adequacy; and develop alternatives for water system improvements. The scope of services is as follows: GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 11 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' 1. Data review of information provided by the Town. 2.

Perform two pipe condition tests and six hydrant fire flow tests at strategic locations in the West Hill distribution system to assist in calibrating the model. 4. Development of separate computer-based hydraulic models of the South Hill and West Hill water distribution systems. 5. Calibration of the models based on data provided by the Town and collected in the field. 6. Evaluation of the adequacy of the South Hill and West Hill distribution systems and water storage tanks under existing conditions and future demands. 7. Identification and evaluation of distribution system deficiencies. 8. Development and analysis of alternatives for water storage tank replacement and water system improvements. 9. Development of opinions of cost for construction of the improvement alternatives. 10. Delivery of the calibrated water system model to the Town. Before delivery to the Town, the South and West Hill models were combined into a single model. 11. Presentations of GHD's findings and identified improvement alternatives to the Town's Public Works Staff, Public Works Committee, and Town Board.

Existing Conditions 2.1 Overview The Town of Ithaca, NY is a member of the SCLIWC, five communities formed to create a jointly owned water supply to serve each of the member communities. Member communities include the Towns of Ithaca, Dryden, and Lansing, and the Villages of Lansing and Cayuga Heights. The SCLIWC water system is also commonly referred to as the Bolton Point water system (which is the convention this report will use). The Bolton Point water supply consists of a lake supply from Cayuga Lake, a water treatment plant, and transmission mains to each member community. Each community owns and operates its own water distribution system within its municipal boundaries. The South Hill water system is located in the southern portion of the Town of Ithaca and is bordered by the City of Ithaca (City)to the north and the Towns of Danby and Newfield to the south. Ithaca College is supplied from, and located within, the South Hill service area, but maintains its own separate water system. The South Hill system serves a total of 958 water services and is supplied from the Bolton Point transmission main from the Pearsall Place CV/PRV connection (see Figure 2-1). The West Hill Water system is located in the west part of the Town of Ithaca and borders the City to the west and the Town of Ulysses to the north. The West Hill service area serves a total of 537 water services and is supplied from the Stone Quarry CV/PRV connection (see Figure 2-2). 2.2 Systemri ti , South Hill The South Hill system consists of three service zones. The Northview/Danby area serves the lower elevation; the Troy Road and Ridgecrest areas serve the higher elevations. The South Hill system was originally constructed in the early 1950s and has been expanded and improved since then. 2.2.1 Northview/Danby Service Area The Northview service area is supplied by the Pearsall Place CV/PRV station located on Pearsall Place. The Pearsall Place CV/PRV is supplied by Bolton Point's transmission main and South Hill tank (through the 16-inch Bolton Point transmission main). The CV/PRV supplies water into the Northview distribution system via a series of 6-, 8-, 10-, and 12-inch water mains which fill the Northview and Danby tanks. The Northview and Danby tanks are both 500,000-gallon glass-lined, bolted steel, ground level water storage tanks; they each have the same base elevation and float off of one another. The Northview/Danby service area supplies approximately 220 water services at an average daily demand of 130,000 gpd. The Pearsall Place CV/PRV is automatically controlled based on the water level in the Northview and Danby tanks. The CV/PRV opens and closes based on high and low level setpoints for the tank. The CV/PRV remains closed until the tank drops to its low level setpoint. At the tank low level setpoint, the valve opens to fill the Northview and Danby tanks. The PRV features of the valve GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 13 amlP(11i1I11pF M.4II ��fluVflll IIIIIIIIIIV�I WUM�' reduce the pressure from the Bolton Point transmission main to prevent the distribution system from being overpressurized while the tanks are filling. 2.2.2 Troy Road Service Area The Troy Road service area is supplied by the Coddington Road Pump Station which pumps directly into the Troy Road water storage tank. The Troy Road tank is a 120,000-gallon glass-lined bolted steel ground level water storage tank which supplies water to the entire Troy Road service area.

The majority of the existing pipe network is constructed of ductile iron with a predominant diameter of 8 inches. Table 2-4 summarizes the diameter and approximate total length of each type of pipe in the system, as obtained from Town records.

The Woolf Lane Pump Station fills the Town of Ulysses' Iradel tank,which supplies the Van Dorns/Ulysses distribution system. The Van Dorns/Ulysses service area was not part of this study. The Van Dorns/Ulysses service area reportedly supplies an average of 38,000 gpd.

Data Collection The first task in the study was the collection of information on the existing water distribution system. Sources of information included record documents provided by the Town, field testing, and meetings with Town personnel to clarify any outstanding questions or uncertain items from the record documents. 3.1 Record Documents The Town maintains numerous records of the water system which were combined with field testing data to create the water system model. The following records were provided by the Town and were used in this study: 1. Pipe sizes, locations, and age. 2. Locations of valves and hydrants, valve status. and pressure settings. 3. Record drawings for portions of the water system installation. 4. Average water consumption for each tank zone from 2014 to 2017. 5. Pump station data and pump curves. 6. Master meter data for water entering each service area. 3.2 Hydrant Flow and PipeCondition Tests, South Hill The Town assisted in conducting 11 hydrant flow tests and 2 pipe condition tests at strategic locations in the South Hill system. Locations of the hydrant flow tests were selected to provide a distribution across the system. Five of the hydrant flow tests and the pipe condition tests were performed on September 7, 2017, and six of the hydrant flow tests were performed on January 18, 2018. The larger West King Road PRV had a mechanical fault during the hydrant tests performed on September 7 which likely impacted the results of the hydrant tests; therefore, calibration of the Troy Road and Ridgecrest service zones was unsuccessful using results of the hydrant flow tests performed on that date. Calibration is further discussed in Section 5. Maps of the hydrant flow test and pipe condition test locations performed on September 7, 2017 and January 18, 2018 are provided in Figures 2-1 and 2-3, respectively. Each hydrant flow test was conducted using two adjacent hydrants. One hydrant was used as the flowing hydrant (fully open), and the static pressure and residual pressure was measured at the second hydrant. The hydrant flow rate was measured at the flowing hydrant using a diffuser with an integral pitot tube and gauge. Personnel from the Town of Ithaca and Bolton Point were present and operated the hydrants for each test. The status of all pumps, CVs, PRVs, and water levels in each of the five water storage tanks was monitored and recorded during these tests for later use in the model. The results of the hydrant flow tests performed in the Northview/Danby service zone on September 7, 2017 and the results of the hydrant flow tests performed in the Troy Road and Ridgecrest service zones on January 18, 2018 are presented in Table 3-1.

The result is a measurement of the pressure drop through a particular section of water main, which can then be used to estimate the C-value roughness coefficient for that section of water main. To provide an accurate measurement of flow, the test must be performed on an isolated section of pipe such that water can only flow through the section of pipe from one source, in one direction. If the pipe is part of a loop, one of the ends of the loop must be isolated. The locations of the two pipe condition tests were selected because of their close representation of the two larger pressure zones (Ridgecrest and Northview). An isolation valve was closed for both pipe condition tests in the South Hill water system. No pipe condition test was conducted in the Troy Road service area, as most of the water mains have been replaced since the late 1980s/early 1990s; therefore, C-value can be estimated based on age. The two pipe condition tests were performed on Kendall Avenue/Pennsylvania Avenue and Danby Road. The results of the pipe condition tests are presented in Table 3-2. We believe there is an error in the data for the pipe condition test on Danby Road because the results are not realistic. The water main on which the Danby Road pipe condition was conducted is downstream of a dual PRV station. The two PRVs have different setpoints which likely skewed the results of the pipe condition test.

The two pipe condition tests were performed on Seven Mile Drive and West Haven Road. For both pipe condition tests in the West Hill water system, the existing piping already restricted the flow of water to one direction, so it was not necessary to close any valves for the test.

Model Development A water distribution system model is used to mathematically simulate hydraulic conditions in pipe networks. The hydraulic analysis was performed using WaterGEMS Version V8i, designed and distributed by Bentley Systems, Inc. Figures 4-1 and 4-2 provide a schematic of the existing water distribution system in the model for the South Hill and West Hill systems, respectively. A steady-state simulation was performed for the existing network. This analysis is based on constant demand and boundary conditions. To establish boundary conditions, the models include distribution pipe information, customer demand data, pump performance curves, and storage tank level data. The model of each system includes the following: 1. Three pressure zones (water service areas). 2. All water distribution mains sized 4 inches in diameter and larger. 3. Four ground level water storage tanks for the South Hill system model and three ground level water storage tanks for the West Hill system model. 4. Two pump stations. 5. Existing average daily water demands and estimated maximum daily and peak hour demands for each customer. 6. Projections for future water demand increases. 7. Elevations based on Town-supplied GIS contour data. 8. Pressure reducing and control valves. 4.1 Softwareti WaterGEMS Version V8i software by Bentley Systems was selected as the preferred modeling software. WaterGEMS allows for simultaneous integration and use of geospatial software. Since the Town currently utilizes WaterCAD, WaterGEMS was selected based on ease of opening the model in both WaterGEMS and WaterCAD. Also, due to the majority of the data being GIS centered, WaterGEMS was selected based on its ability to provide a hydraulically calibrated model for system analysis while being fully integrated with GIS data. 4.2 Model InputsConditions Model inputs were based on imported data from the GIS map developed using ArcGIS. The model incorporated all hydraulic features and relevant asset fields from the GIS map as a basis. The GIS data was then supplemented with any additional data required for model analysis using available Town records. Additional model inputs are summarized below. 4.2.1 System Pipe Network Distribution pipes 4 inches in diameter and larger were included in the model. Pipes smaller than 4 inches are generally individual water services and do not have a significant impact on system GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 113 P,�aamlP(11i1I110 m.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' capacity. The general layout of the system pipe network was interpreted from hydraulic GIS data provided by the Town (as discussed in Section 3). Pipe diameters were based on GIS information, record drawings, and other input from Town personnel. 4.2.2 Hydrants All known hydrants in each service area were provided in the form of GIS data and included in the model. Hydrants were numbered using the WaterGEMS numbering system. The modeling software was used to assign elevations to the hydrants based on contour GIS data provided by the Town. 4.2.3 Hydrant Branches Hydrant branches were included in the Town-supplied GIS data and were therefore included in the model. Hydrant branch sizes were obtained from the Town's GIS data and record drawings. 4.2.4 Mainline Valves All of the Town's mainline valves, which were provided by the Town in the form of GIS data, were included in the model. Valves were numbered based on the WaterGEMS numbering system. Valve elevations were determined from the same contour data used for the hydrants. All valves were modeled open except for those that separate the two pressure zones. 4.2.5 Junction Nodes Junction nodes were developed automatically by the modeling software at major pipe bends, pipe intersections, and all hydrant branches. Water demands were allocated to junctions (Section 4.3). 4.2.6 Coddington Road Pump Station, South Hill In order to model the Coddington Road Pump Station pumps, multiple sources were reviewed, including equipment data sheets and daily pump station readings. Physical elevations and pump manufacturer's performance curves were entered into the model for the pump station. Table 4-1 is a summary of additional pump details.

Further details on the existing water storage tanks are provided in Section 2.3. 4.2.11 Water Supply and CV/PRVs, South Hill The South Hill service areas are supplied by the Bolton Point transmission main and the East Hill tank, through the Pearsall Place CV/PRV connection. This transmission main and the East Hill tank GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 116 P,�aamlP(11i1I110 m.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' are supplied by Bolton Point's Oakcrest Pump Station. The PRV was modeled and the downstream pressure of each PRV was set based on the following Town-supplied setpoints: • Pearsall Place CV/PRV Open — Northview/Danby tanks at 28 feet • Pearsall Place CV/PRV Close—Northview/Danby tanks at 32 feet • Downstream pressure setting when open—156 psi The East Hill tank was modeled as a reservoir (water storage with infinite supply)to the Pearsall Place CV/PRV. The East Hill tank was modeled with a water elevation of 1,180 feet (equivalent to 20 feet of water in tank or 10 feet below overflow). 4.2.12 Water Supply and CV/PRVs, West Hill The West Hill service areas are supplied by the Town's transmission main, through the Stone Quarry CV/PRV connection. This transmission main is supplied by the Northview/Danby service area, which is supplied by the Pearsall Place CV/PRV. The Stone Quarry CV/PRV was modeled and the downstream pressure of each PRV was set based on the following Town-supplied setpoints: • Stone Quarry CV/PRV Open — Bostwick Road tank at 26 feet • Stone Quarry CV/PRV Close— Bostwick Road tank at 35 feet • Downstream pressure setting when open—95 psi The Trumansburg Road service area is supplied by the Trumansburg Road tank, through the Trumansburg Road CV/PRV. The Trumansburg Road CV/PRV was modeled and the downstream pressure of each PRV was set based on the following Town-supplied setpoints: • Trumansburg Road CV/PRV Open—Trumansburg Road tank at 33 feet • Trumansburg Road CV/PRV Close—Trumansburg Road tank at 36 feet • Downstream pressure setting when open— 16 psi 4.3 Evaluationt Once the model was constructed in WaterGEMS, demand data was allocated throughout the system to simulate actual conditions. Individual customer meter demands were added to the model according to the address/tax parcel on the account. Average daily water demands were then allocated to water main nodes in the model based on the closest node to the meter, unless Town records suggested otherwise. 4.3.1 Average Daily Demand, South Hill The average daily demands for the water system were determined over the period of May 2014 through May 2017 from quarterly water billing accounts recorded by Bolton Point and flow meter readings at the control valve and pump stations. The average daily demands were calculated for each 12-month period as the sum of total water delivered for 12 months divided by 365 days (366 days for the period encompassing 2016). The highest water demand for the three 12-month GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 117 �,aamlP��SI(�1N�oa �fluVflll IIIIIIIIIIV�I IIWUa�' periods was used in the model. The period of May 2015-May 2016 provided the highest average daily water demands for the South Hill service areas. The demands from this period are summarized in Table 4-5.

The average daily demands were calculated for each 12-month period as the sum of total water delivered for 12 months divided by 365 days (366 days for the period encompassing 2016). The period of May 2015-May 2016 was used in the model. This period did not provide the highest water demand for the three 12-month periods, but was used to be consistent with the data used for the South Hill model. The demands from this period are summarized in Table 4-6.

The model incorporates both metered water and unaccounted-for water. This was accomplished by allocating actual meter demands to parcels throughout the distribution system using tax ID information. The unaccounted-for water was then evenly distributed throughout the model to each parcel. This distributes the water demand across the system in a way which best represents the demand conditions in the Town. 4.3.4 Demand Conditions The maximum day and peak hour demands were estimated by applying commonly used peaking factors to average daily demands. The maximum day demand factor used was 1.7 times the average daily demand. The peak hour demand factor was 2.0 times the maximum day demand. These maximum day and peak hour factors were used to create the demands in the model. Tables 4-7 and 4-8 summarize the modeled average daily, maximum day, and peak hour demands in the South Hill and West Hill water models, respectively.

Model Calibration 5.1 Calibration Methodology After the model was constructed and demand was allocated to appropriate meters in the model, the model was calibrated based on field-obtained test data. Hydrant flow tests and pipe condition tests, performed as discussed in Section 3, were used to compare the model output versus actual system conditions. This data was used to calibrate the model based on static and residual pressures. Calibration was performed by adjusting model parameters until model outputs generally agreed with field-measured information. The model was calibrated for a steady-state scenario, which models a single point in time and is used to check static and residual pressures in the water system. Both demand and SCADA records received from the Town were used as criteria for the steady-state calibration. The calibration goal used for the model was to be within ±10 percent of the static and residual pressures from field tests for pressures above 50 psi and ±5 psi for pressures less than 50 psi. 5.2 Pipet r I Roughness An important parameter in calibrating the system model is the Hazen-Williams roughness coefficient, or C-value. This factor represents the roughness of the pipe interior and the pipe's resistance to flow. A lower C-value represents more friction and greater resistance to flow. The C-value tends to decrease with pipe age due to corrosion and deposition inside the pipe, although studies have shown that cement-lined piping can maintain a higher C-value for longer when compared to unlined piping.' The C-value for new cement-lined ductile iron pipe is typically 130. As the pipe ages, this value could potentially decrease, resulting in greater resistance to flow and reduction in system capacity. In general, the greater the pipe age, the lower the modeled C-value. 5.3 Calibration , South Hill The calibration used the results of two hydrant flow tests and two pipe condition tests performed on September 7, 2017 and six hydrant flow tests performed on January 18, 2018. Hydrant flows measured in the field were simulated in WaterCAD using modeled hydrants corresponding to field- tested hydrants. Model parameters were adjusted to achieve simulated hydrant flow test results within the goal of±10 percent of field test data for steady-state model calibration. The model was calibrated based on the average daily demand condition. First, the water storage tank level information at the time of field testing was entered from SCADA monitored data. Following static calibration, the second calibration effort used residual pressure data from fire flow testing to calibrate the model under the field-recorded fire flow (see Table 3-1). The Hazen-Williams' C-values were modified as needed across the system to correlate model residual pressures with those observed in the field. ' Ductile Iron Pipe Research Association (DIPRA). 2016.

Model calibration was undertaken separately in each pressure zone. The typical C-value used in the model was 130; the maximum C-value used was 150, which was considered reasonable based on literature published by the Ductile Iron Pipe Research Association.' For the East King Road (West King PRV) hydrant test, the model initially predicted a significantly lower residual pressure than measured in the field. After additional hydrant testing to confirm these results, the pipe size for the water main on the portion of East King Road between Ridgecrest Road to the east and Hydrant No. Q0930 to the west was increased from 8-to 10-inch. With an 8-inch pipe size, the modeled residual pressure for this test was lower than the field measured data by 39 percent. With a 10-inch pipe size, the modeled residual pressure for this test is higher than the field measured data by 3 percent. For the Coddington Road hydrant test, the model initially predicted a significantly lower residual pressure than measured in the field. As a result, the pipe size for the water main on the portion of Coddington Road between Troy Road to the north and East King Road to the south was increased from 8-to 10-inch. With an 8-inch pipe size, the modeled residual pressure for this test was lower GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 121 P,�aamlP(11i1I110 m.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' than the field measured data by 42 percent. With a 10-inch pipe size, the modeled residual pressure for this test is higher than the field measured data by 2 percent. Additional hydrant tests were performed to confirm these results. For both the Coddington Road and East King Road pipes, Town records indicate the pipe sizes are 8-inch diameter. Site investigations were unable to confirm the presence of 10-inch diameter piping or any other conditions that might cause the discrepancy between the model and field data. To increase the accuracy of the modeled hydraulic results, it was decided to configure the model to match field test conditions. With hydraulic models, there are inaccuracies in pressure gauges, variations in field measurements, and variations in the distribution system that cannot be easily quantified, making it impractical to achieve an accuracy of 100 percent in all cases. Based on the results presented in Table 5-1, the model was deemed calibrated and adequate for completing further analysis on the South Hill water system. 5.4 Calibration , West Hill The calibration used the results of the six hydrant flow tests and two pipe condition tests performed on September 5, 2017. Hydrant flows measured in the field were simulated in WaterCAD using modeled hydrants corresponding to field-tested hydrants. Model parameters were adjusted to achieve simulated hydrant flow test results within the goal of±10 percent of field test data for steady-state model calibration. The model was calibrated based on the average daily demand condition. First, the water storage tank level information at the time of field testing was entered from SCADA monitored data. Following static calibration, the second calibration effort used residual pressure data from fire flow testing to calibrate the model under the field-recorded fire flow (see Table 3-3). The Hazen- Williams' C-values were modified as needed across the system to correlate model residual pressures with those observed in the field. Table 5-2 presents the results from final model calibration and a comparison of model values with hydrant flow test results. All except one of the six modeled static and residual pressures are within the ±10 percent goal for steady-state model calibration.

(1) Field-measured residual pressures are±1 psi. Model calibration was undertaken separately in each pressure zone. The typical C-value used for new ductile iron pipes is 130. For the Trumansburg Road hydrant test, the model initially predicted a higher residual pressure than measured in the field. As a result, the C-value for the water main on the portion of Trumansburg Road between Hayts Road (County Road 139)to the north and Hillcrest Drive to the south was decreased to 110. This is reasonable because rocks and debris were flushed out of the water main during the hydrant test, increasing the headloss in the pipe. With a C-value of 130, the modeled residual pressure for this test was higher than the field-measured data by 12 percent. With a C-value of 110, the modeled residual pressure for this test is higher than the field-measured data by 8 percent. This resulted in the model outputs for all tested hydrants performing within 10 percent of the field-measured data with the exception of one hydrant discussed below. Using a C-value lower than 110 for the water main was considered to be unreasonable based on the pipe age and material, so no further changes were made to the model. The remainder of the Trumansburg service area did not require changing of the pipe C-values from the original 130. The Woolf Lane Pump Station and Iradel tank were included in the model to account for the demand of the Woolf Lane Pump Station on the Trumansburg tank area. A hydrant test was performed on the Iradel tank zone, the results of which are presented in Table 3-3. The Iradel tank is located in the Van Dorns service area in the Town of Ulysses,just north of the Trumansburg Road service area, and was not included in the scope of the calibration and analysis. For the reasons provided in Section 5.3, it is impractical to achieve an accuracy of 100 percent in all cases. Based on the results presented in Table 5-2, the model was deemed calibrated and adequate for completing further analysis on the West Hill water system.

System Analysis, South Hill Once the South Hill model was deemed to be calibrated, it was utilized to analyze the existing water system and identify areas of improvement. The calibrated model was used to analyze overall water system capacities and pressures, fire flow capacities, and suitability of the existing water storage tanks. The analysis for the South Hill water system is discussed in more detail below. 6.1 Capacityit i the ExistingSystem The model was used to simulate the existing water system under average daily, maximum day, and peak hour demand conditions. It was then evaluated based on system pressure and available fire flow for each of these demand conditions. The distribution system was evaluated against the following criteria: Pressure Evaluation Criteria • Minimum of 35 psi at all customer connections in the distribution system, under normal operating conditions. • Minimum of 20 psi at all points in the distribution system, under fire flow conditions. • Maximum of 100 psi at all points in the distribution system, or pressure reducing valves for any homes over 100 psi, under all operating conditions. • These pressures are in accordance with the Recommended Standards for Water Works (Ten-States Standards, 2012). Fire Flow Evaluation Criteria • Minimum fire flow of 500 gpm at all hydrants in accordance with Insurance Services Office (ISO)guidelines and Ten-States Standards. • Minimum fire flow of 1,500 gpm at all hydrants, as requested by the Town. It should be noted that ISO provides a general guideline that all hydrants provide a minimum fire flow of 500 gpm; however, ISO is able to perform a more detailed evaluation of the distribution system to determine location-specific "needed fire flows"for individual hydrants. Often the ISO's location-specific needed fire flows are greater than 500 gpm. An ISO evaluation of the South Hill water system was not available at the time of this report. The evaluation of the existing system and improvement alternatives discussed in the next section will be based on the fire flow criteria listed above. It is recommended the Town request an ISO evaluation of the South Hill water system in order to obtain specific needed fire flow criteria for these areas. 6.1.1 Water Distribution System Pressures Based on the calibrated model, few areas of low pressure exist and are generally located in the vicinity of the tank in the Northview/Danby, Troy Road, and Ridgecrest pressure zones. These three pressure zones each have areas with high pressures reaching over 100 psi. Figures 6-1, 6-2, and GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 124 ��fluVflll IIIIIIIIIIV�I IIWV��' 6-3 show the existing pressures across the distribution system under average daily, maximum day, and peak hour demand conditions, respectively. As can be seen in the figures, the Coddington Road and Troy Road Pump Stations are off, the Pearsall Place PRV/CV is closed; the larger PRVs (West King 2, Stone Quarry 1 B, Stone Quarry 2B, Stone Quarry 3B) are closed; and the smaller PRVs (West King 1, Stone Quarry 1A, Stone Quarry 2A, Stone Quarry 3A)are active. Based on this analysis, the following observations have been made: 1. The Northview/Danby service area has no customers with pressures below 35 psi under normal conditions, maximum day demand conditions, or peak hour demand conditions. There are some pipes adjacent to the Northview and Danby tanks with less than 20 psi of pressure, but these water mains do not serve any customers. 2. The Northview/Danby service area has several areas that exceed 100 psi, predominately located in the northern portion of the service area. 3. The Troy Road service area has no customers with pressures below 35 psi under normal conditions, maximum day demand conditions, or peak hour demand conditions. There are some pipes adjacent to the Troy Road tank with less than 35 psi of pressure, but these water mains do not serve any customers. 4. The Troy Road service area has several areas that exceed 100 psi throughout the service area. 5. There are five customers in the Ridgecrest service area with pressures below 20 psi and seven customers with pressures below 35 psi under normal conditions. There is one additional customer with pressures below 35 psi under peak hour demand conditions. These customers (13 total) are served by water mains adjacent to the Ridgecrest tank. There are some additional pipes adjacent to and downstream of the West King PRVs with less than 35 psi of pressure, but these water mains do not serve any customers. 6. The Ridgecrest service area has several areas that exceed 100 psi, predominately located in the southern portions of the area. 7. The distribution system pressures do not vary significantly from average daily demands up to peak hour demands. This suggests that the water main capacity is not the limiting factor causing low system pressures. The low system pressures are a result of the elevations of the existing tanks with respect to the customers they serve. Table 6-1 summarizes the maximum and minimum distribution system pressures observed in the model. Pressures are reported under their worst case demand conditions (i.e., minimum pressures under peak hour demand and maximum pressures under average demands). However, as noted above, the majority of pressures do not vary significantly from average to peak demands. Maximum static pressures are also provided, since static conditions can be achieved at night when demands are at their minimum. Pressures exceeding 100 psi have been shown to result in a greater occurrence of breaks in water mains and residential water services. Pressures over 100 psi can also cause damage to water heaters and pipes in residences. For this reason, the Town of Ithaca requires customers with high GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 125 P,�aamlP(11i1I11pF W.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' pressures to install PRVs on their water service connections in accordance with the Ten-States Standards. These individual PRVs can mitigate potential damage to the customer's water piping, but they do not reduce the risk of breaks in the water distribution mains serving these areas. In some cases, it is not feasible to reduce system pressures to below 100 psi due the elevation change and layout of the distribution system. Where possible, it is recommended to reduce system pressures to below 100 psi. Table 6-1 Southill Existing DistributionSystem ss (Model Estimate) � nnntinMEE= .,,,,/�����/ilii /����� /iii %ii/� 6.1.2 Available Fire Flow The model is able to separately estimate the available fire flow at each hydrant in the system. Available fire flows were estimated during the maximum day demand. The analysis does not model the duration of each fire flow with respect to distribution system capacity. The duration of available fire flow is impacted more by the volume of water storage than by the pipe capacity. An analysis of the fire flow duration is discussed in greater detail in Section 6.2. The maximum available fire flows were estimated in the model based on maintaining a minimum pressure of 20 psi at all points in the distribution system, in accordance with Ten-States Standards. The available fire flows are also estimated with the Pearsall Place PRV/CV closed; the Coddington Road and Troy Road Pump Stations off; the larger PRVs (West King 2, Stone Quarry 1 B, Stone Quarry 2B, Stone Quarry 3B)active; and the smaller PRVs (West King 1, Stone Quarry 1 A, Stone Quarry 2A, Stone Quarry 3A) closed. Figure 6-4 provides a map of the distribution system hydrants, color coded based on their available fire flow. Table 6-2 is a summary of the available fire flows in the three service areas. Table 6-2 Southill Fire Flow Analysis of ExistingSystem (Maximum y ) d I j&V/, / %%%%%%%%%%%%%%%%%%%%%%%///i ,,,, �, The majority of hydrants in the Northview/Danby provide fire flows greater than 1,500 gpm. The majority of hydrants in the Troy Road and Ridgecrest pressure zones provide fire flows less than GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 126 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' 1,500 gpm. Fifty-five percent of the hydrants in the Northview/Danby zone provide fire flows greater than 1,500 gpm, while no hydrants in the Troy Road or Ridgecrest zones provide more than 1,500 gpm. Twelve hydrants provide less than 500 gpm fire flow--two in the Northview/Danby pressure zone, six hydrants in the Troy Road pressure zone, and four hydrants in the Ridgecrest pressure zone. The two hydrants in the Northview/Danby pressure zone are located adjacent to the water storage tanks where water pressure is low. The six hydrants in the Troy Road pressure zone are located on Southwoods Drive and Eldridge Circle. The four hydrants in the Ridgecrest pressure zone are located adjacent to the water storage tank where water pressure is low. Alternatives to increase fire flow in the Northview/Danby, Troy Road, and Ridgecrest service areas are discussed in Section 9. Evaluation of the existing fire flows in this report is based on the criteria noted above. The report does not provide recommendations for what the minimum fire flows should be in the distribution system. It is common to reference the ISO's indication of needed fire flow rates as a baseline for comparing water system performance. ISO recommends needed fire flow rates based on building size, construction materials, and use in the area. For one-and two-family residences, ISO's needed fire flows are typically within a range of 500 to 1,500 gpm, but can be significantly higher for other building types and uses. As noted in Section 6.1, it is recommended the Town obtain an ISO evaluation of the Northview/Danby, Troy Road, and Ridgecrest zones for the purpose of comparing ISO's needed fire flows to existing fire flows. 6.2 EvaluationExisting t r Storage Water storage in the distribution system must meet two basic requirements: (1) provide adequate pressure to all water services; and (2) provide an adequate volume of water to meet worst case demands. The pressure requirements for the distribution system are defined in Section 6.1. These requirements dictate the minimum and maximum water elevations for water storage. The volume of water storage necessary to meet Ten-States Standards is based on supplying fire flow and maximum day demands concurrently without interruption of supply to water services. The distribution system must meet these demands without dropping below 20 psi at any point in the system. The Town also desires to provide three days of water storage for all of their water storage tanks. These criteria were used to evaluate the existing water storage tanks in the three pressure zones. The minimum required storage volume is equal to the higher value of either three days of storage or the volume needed to meet water and fire demands. The minimum storage volume for each tank to meet water and fire demands, as defined by Ten- States Standards, is calculated based on the combined fire flow and maximum day water system demands. For the Northview/Danby, Troy Road, and Ridgecrest pressure zones, this calculation will be based on the following assumptions: 1. The fire flow rate is equal to 1,500 gpm, as desired by the Town. 2. The duration of the fire flow is 2 hours (this is the duration selected by ISO for fire flow rates up to 2,500 gpm). GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 127 ��fluVflll IIIIIIIIIIV�I IIWV��' 3. The water demand during a fire is at the maximum day rate (the analysis also assumes that one hour of the fire occurs during the peak hour demand of the maximum day). 4. The maximum and peak hour demands for Northview/Danby do not include Ithaca College, as the college has their own tank for fire protection. 5. When calculating the volume for Northview/Danby, we assume the Pearsall Place CV/PRV is open for the entire duration of a fire, supplying water to the tanks. 6. When calculating the volume for Northview/Danby, we assume the Coddington Road Pump Station is running both pumps (pumping out of the Northview and Danby tanks)for the entire duration of a fire. This is an added demand on the Northview and Danby tanks. 7. When calculating the volume for Northview/Danby, the demand necessary to fill the Bostwick Road tank is included. The Bostwick Road tank is filled from the Stone Quarry CV/PRV. Since it takes less than 2 hours for the Stone Quarry CV/PRV to fill the Bostwick Road tank, and the minimum storage volume calculations are based on a 2-hour period, the Bostwick demand is based on the volume required to fill the Bostwick tank, as opposed to using the Stone Quarry CV/PRV demand over a period of 2 hours. 8. When calculating the volume for Troy Road, we assume the Coddington Road Pump Station is running both pumps for the entire duration of a fire, supplying water to the tank. 9. When calculating the volume for Troy Road, we assume the Troy Road Pump Station is running both pumps (pumping out of the Troy Road tank)for the entire duration of a fire. This is an added demand on the Troy Road tank. 10. When calculating the volume for Ridgecrest, we assume the Troy Road Pump Station is running both pumps for the entire duration of a fire, supplying water to the tank. 11. The water storage tanks start at their maximum water level. Once the total required water storage volume is calculated, it must be compared to the actual usable volume in the existing water storage tanks. As noted above, the pressure in the distribution system must not drop below 20 psi during a fire. The usable water storage in a tank is based on providing this 20 psi minimum pressure to all customers. For the Northview, Danby, and Troy Road tanks, at least 20 psi of pressure is provided to all customers when the water level is at the bottom of the tank, so the entire storage volume is usable in these tanks. For practicality, we have calculated the usable water storage volume as the water above 1 foot from the bottom of the tank. In other words, the bottom 1 foot of water was subtracted from the usable storage volume. For the Ridgecrest tank, there are customers with less than 20 psi of pressure under normal conditions. For this reason, customers (13 total) adjacent to the Ridgecrest tank with less than 35 psi when the tank level is at the pump setpoint (35 feet of water in the tank) under normal and peak hour conditions are not included in determining the usable water storage volume. A primary recommendation to the Town (discussed later) is to provide a booster pump system to increase the pressure to these customers. The water storage analysis herein assumes that the booster system has been provided. Excluding these customers, at least 20 psi of pressure is provided to all other GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 128 pp ! ��fluVflll IIIIIIIIIIV�I IIWUM�' customers when the water level is 1 foot above the bottom of the tank, meaning the usable water storage volume in the Ridgecrest tank is the water above 1 foot from the bottom of the tank. Table 6-3 summarizes the water storage required for each pressure zone, based on water and fire demands and providing three days of storage. The table also shows the usable water storage available in the existing tanks.

(9) Storage available with 1 foot of water remaining in the Ridgecrest tanks. The existing Northview/Danby and Ridgecrest tanks provide enough storage to meet current water and fire demands with the PRV and pumps operational. The estimated water storage for the Northview/Danby and Ridgecrest tanks under these conditions is 152,600 and 155,400 gallons, respectively. The existing Troy Road tank does not provide sufficient storage to meet current water and fire demands with the pumps operational. The estimated water storage for the Troy Road tank under these conditions is 168,000 gallons and the usable storage available is 124,400 gallons. The Town also seeks to provide three days of storage in each tank under average daily demand conditions, in the event of a large power failure. During a power failure, the pumps and PRVs will not operate normally to fill the tanks. Having three days of storage provides the Town time to fill the tanks under emergency operations. The minimum water storage volume required for the Northview/Danby pressure zone to provide three days of storage is 390,000 gallons. The existing tanks provide a usable volume of 1,015,200 gallons; therefore, the Northview/Danby tanks have sufficient storage volume to meet the Town's desired storage capacity. The minimum water storage volume required for the Troy Road pressure zone to provide three days of storage is 81,300 gallons. The existing tank provides a usable volume of 124,400 gallons; therefore, the Troy Road tank has sufficient storage volume to meet the Town's desired storage capacity. The minimum water storage volume required for the Ridgecrest pressure zone to provide three days of storage is 403,200 gallons. The existing tank provides a usable volume of 489,200 gallons; therefore, the Ridgecrest tank has sufficient storage volume to meet the Town's desired storage capacity. The Town should consider providing additional storage for the Troy Road service area to meet current water and fire demands. Since pressures in the Troy Road service areas are adequate, the new storage can use the same elevations as the existing Troy Road tank. Section 8 provides an evaluation of the South Hill system under projected future water demands, and improvement alternatives are discussed in more detail in Section 9.

System Analysis, West Hill Once the West Hill model was deemed to be calibrated, it was utilized to analyze the existing water system and identify areas of improvement. The calibrated model was used to analyze overall water system capacities and pressures, fire flow capacities, and suitability of the existing water storage tanks. The analysis for the West Hill water system is discussed in more detail below. 7.1 Capacityit i the ExistingSystem The model was used to simulate the existing water system under average daily, maximum day, and peak hour demand conditions. The water system was then evaluated based on system pressure and available fire flow for each of these demand conditions. The distribution system was evaluated against the following criteria: Pressure Evaluation Criteria • Minimum of 35 psi at all customer connections in the distribution system, under normal operating conditions. • Minimum of 20 psi at all points in the distribution system, under fire flow conditions. • Maximum of 100 psi at all points in the distribution system, or pressure reducing valves for any homes over 100 psi, under all operating conditions. • These pressures are in accordance with the Recommended Standards for Water Works (Ten-States Standards, 2012). Fire Flow Evaluation Criteria • Minimum fire flow of 500 gpm at all hydrants in accordance with ISO guidelines and Ten- States Standards. • Minimum fire flow of 1,500 gpm at all hydrants, as requested by the Town. As stated in Section 6, ISO provides a general guideline that all hydrants provide a minimum fire flow of 500 gpm; however, ISO is able to perform a more detailed evaluation of the distribution system to determine location-specific "needed fire flows"for individual hydrants. Often the ISO's location-specific needed fire flows are greater than 500 gpm. An ISO evaluation of the West Hill water system was not available at the time of this report. The evaluation of the existing system and improvement alternatives discussed in the next section will be based on the fire flow criteria listed above. It is recommended the Town request an ISO evaluation of the West Hill water system in order to obtain specific needed fire flow criteria for these areas. 7.1.1 Water Distribution System Pressures Tanks Draining(Pumps Off and Control Valves Closed) Based on the calibrated model, few areas of low pressure exist and are generally located in the vicinity of the tank in the Bostwick Road, West Hill, and Trumansburg Road pressure zones. These GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 131 amlP(11i1I11pF M.4II ��fluVflll IIIIIIIIIIV�I WUM�' three pressure zones each have areas with high pressures reaching over 100 psi. Figures 7-1, 7-2, and 7-3 show the existing pressures across the distribution system when all CV/PRVs are closed and pump stations are off under average daily, maximum day, and peak hour demand conditions, respectively. Based on this analysis, the following observations have been made: 1. The Bostwick Road service area has no customers with pressures below 35 psi under normal conditions. There are some pipes adjacent to the Bostwick Road tank with less than 35 psi of pressure, but these water mains do not serve any customers. 2. The Bostwick Road service area has several areas that exceed 100 psi, predominately located in the eastern portion of the service area. 3. There are six customers in the West Hill service area with pressures below 35 psi under normal conditions. In addition, the water main that serves the Ithaca Ecovillage has less than 35 psi of pressure but the Ecovillage is not included as one of the six customers stated above since the Ecovillage has its own pump station (not shown in model). 4. The West Hill service area has few areas that exceed 100 psi, predominately located in the southernmost portion of the service area. 5. There is one customer in the Trumansburg Road service area with pressure below 35 psi under normal conditions. 6. The Trumansburg Road service area has several areas that exceed 100 psi, predominately located in the northern and southern portions of the service area. 7. The distribution system pressures do not vary significantly from average daily demands up to peak hour demands. This suggests the water main capacity is not the limiting factor causing lower system pressures. The low system pressures are a result of the elevations of the existing tanks with respect to the customers they serve. Tanks Filling(Pumps On and Control Valves Open) Typically when pumps/control valves are on/open, the storage tanks are filling and system pressures are higher than when the pumps and control valves are off/closed. However, as discussed below, that is not always the case for the West Hill service area. The following observations have been made under average daily demand conditions with the smaller Stone Quarry control valve active (not closed), the larger Stone Quarry control valve closed, the Coy Glen Pump Station with one pump on, the larger Trumansburg control valve active (not closed), the smaller Trumansburg control valve closed, and the Woolf Lane Pump Station with one pump on: 1. The number of customers with pressures below 35 psi does not change in the Bostwick Road and Trumansburg Road service areas. 2. The number of customers with pressures below 35 psi increases from 6 customers to 11 customers in the West Hill service area. Under these conditions, there is approximately 580 gpm of flow out of the Coy Glen Pump Station and approximately 990 gpm of flow through the Trumansburg PRV. Based on this, flow out of the West Hill tank is greater than GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 132 P,�aamlP(11i1I110 m.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' flow into the West Hill tank, causing the water level in the tank to drop and the number of customers with less than 35 psi to increase. 3. When the Trumansburg CV/PRV is open, the high flow rate it draws decreases the pressures in the West Hill service area. Discussion Table 7-1 summarizes the maximum and minimum distribution system pressures observed in the model with CV/PRVs closed and pump stations off. Pressures are reported under their worst case demand conditions (i.e., minimum pressures under peak hour demand and maximum pressures under average demands). However, as noted above, the pressures do not vary significantly from average to peak demands. Maximum static pressures are also provided, since static conditions can be achieved at night when demands are at their minimum. Pressures exceeding 100 psi have been shown to result in a greater occurrence of breaks in water mains and residential water services. Pressures over 100 psi can also cause damage to water heaters and pipes in residences. The Town of Ithaca requires customers with high pressures to install PRVs on their water service connections in accordance with the Ten-States Standards. These individual PRVs can mitigate potential damage to the customer's water piping, but they do not reduce the risk of breaks in the water distribution mains serving these areas. In some cases, it is not feasible to reduce system pressures to below 100 psi, due the elevation change and layout of the distribution system. Where possible, it is recommended to reduce system pressures to below 100 psi.

Available fire flows were estimated during the maximum day demand. The analysis does not model the duration of each fire flow with respect to distribution system capacity. The duration of available fire flow is impacted more by the volume of water storage than by pipe capacity. An analysis of the fire flow duration is discussed in greater detail in Section 7.2. The maximum available fire flows were estimated in the model based on maintaining a minimum pressure of 20 psi at all points in the distribution system, in accordance with Ten-States Standards.

Seven hydrants provide less than 500 gpm: one hydrant in the Bostwick Road pressure zone, four hydrants in the West Hill pressure zone, and two hydrants in the Trumansburg Road pressure zone. All hydrants that provide less than 500 gpm are located adjacent to the water storage tank in the pressure zone, where water pressure is low. Alternatives to increase the fire flow in the Bostwick Road, West Hill, and Trumansburg Road service are discussed in Section 10. Evaluation of the existing fire flows in this report is based on the criteria noted above. The report does not provide recommendations for what the minimum fire flows should be in the distribution system. It is common to reference the ISO's indication of needed fire flow rates as a baseline for comparing water system performance. ISO recommends needed fire flow rates based on building size, construction materials, and use in the area. For one- and two-family residences, ISO's needed fire flows are typically within a range of 500 to 1,500 gpm, but can be significantly higher for other building types and uses. As noted in Section 7.1, it is recommended the Town obtain an ISO evaluation of the Bostwick Road, West Hill, and Trumansburg Road zones for the purpose of comparing ISO's needed fire flows to existing fire flows. 7.2 EvaluationExisting t r Storage Water storage in the distribution system must meet two basic requirements: (1) provide adequate pressure to all water services; and (2) provide an adequate volume of water to meet worst case demands. The pressure requirements for the distribution system are defined in Section 7.1. These requirements dictate the minimum and maximum water elevations for the water storage. The volume of water storage necessary to meet Ten-States Standards is based on supplying fire flow and maximum day demands concurrently without interruption of supply to water services. The distribution system must meet these demands without dropping below 20 psi at any point in the system. The Town also desires to provide three days of water storage for all of their water storage GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 134 �fluVflll IIIIIIIIIIV�I IIWV�' tanks. These criteria were used to evaluate the existing water storage tanks in both pressure zones. The minimum required storage volume is equal to the higher value of either three days of storage or the volume needed to meet water and fire demands. The minimum storage volume for each tank to meet water and fire demands, as defined by Ten- States Standards, is calculated based on the combined fire flow and maximum day water system demands. For the Bostwick Road, West Hill, and Trumansburg Road pressure zones, this calculation will be based on the following assumptions: 1. The fire flow rate is equal to 1,500 gpm, as desired by the Town. 2. The duration of the fire flow is 2 hours (this is the duration selected by ISO for fire flow rates up to 2,500 gpm). 3. The water demand during a fire is at the maximum day rate (the analysis also assumes that one hour of the fire occurs during the peak hour demand of the maximum day). 4. When calculating the volume for Bostwick Road, we assume the smaller Stone Quarry CV/PRV is open for the entire duration of a fire, supplying water to the tank. It is assumed the smaller CV/PRV is open because the modeled pressure downstream of the CV/PRVs is not low enough to result in the opening of the larger Stone Quarry CV/PRV. Based on the SCADA data provided by Bolton Point, the large Stone Quarry CV/PRV never opened during the period of July, August, and September 2017. 5. When calculating the volume for the Bostwick Road tank, we assume the Coy Glen Pump Station is running one pump (pumping out of the Bostwick Road tank)for the entire duration of a fire. This is an added demand on the Bostwick Road tank. 6. When calculating the volume for West Hill, we assume the Coy Glen Pump Station is running one pump for the entire duration of a fire, supplying water to the tank. 7. When calculating the volume for West Hill, we assume the Trumansburg Road CV/PRV is open (drawing out of the West Hill tank)for the entire duration of a fire. This is an added demand on the Bostwick Road tank. 8. When calculating the volume for Trumansburg Road, we assume the Trumansburg Road CV/PRV is open for the entire duration of a fire, supplying water to the tank. 9. When calculating the volume for Trumansburg Road, we assume the Woolf Lane Pump Station is running one pump (pumping out of the Trumansburg Road tank)for the entire duration of a fire. This is an added demand on the Trumansburg Road tank. 10. The water storage tanks start at their maximum water level. Once the total required water storage volume is calculated, it must be compared to the actual usable volume in the existing water storage tanks. As noted above, the pressure in the distribution system must not drop below 20 psi during a fire. The usable water storage in a tank is based on providing this 20 psi minimum pressure to all customers. There is at least 20 psi of pressure provided to all customers when the water level is at the bottom of the Bostwick Road and West Hill tanks, and 12 feet above the bottom of the Trumansburg Road tank. For practicality, we have GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 135 ��fluVflll IIIIIIIIIIV�I IIWV��' calculated the usable water storage volume in the Bostwick Road and West Hill tanks as 1 foot above the bottom of the tank. Table 7-3 summarizes the water storage required for each pressure zone, based on water and fire demands and providing three days of storage. The table also shows the usable water storage available in the existing tanks.

The existing Bostwick Road tank does not provide enough storage to meet current water and fire demands with the pump and PRVs operational. The estimated water storage for the Bostwick Road tank under these conditions is 207,300 gallons. The usable storage available in the Bostwick Road tank is 190,400 gallons. The existing West Hill and Trumansburg Road tanks provide enough storage to meet current water and fire demands with the pump and PRV operational. The estimated water storage for the West Hill and Trumansburg Road tanks under these conditions is 239,300 and 145,300 gallons, respectively. The Town also seeks to provide three days of storage in each tank under average daily demand conditions, in the event of a large power failure. During a power failure, the pumps and PRV will not operate normally to fill the tanks. Having three days of storage provides the Town time to fill the tanks under emergency operations. The minimum water storage volume required for the Bostwick Road pressure zone to provide three days of storage is 168,000 gallons. The existing tank provides a usable volume of 190,400 gallons; therefore, the Bostwick Road tank has sufficient storage volume to meet the Town's desired storage capacity under existing demands. The minimum water storage volume required for the West Hill pressure zone to provide three days of storage is 197,400 gallons. The existing tank provides a usable volume of 958,500 gallons; therefore, the West Hill tank has sufficient storage volume to meet the Town's desired storage capacity. The minimum water storage volume required for the Trumansburg Road pressure zone to provide three days of storage is 421,200 gallons. The existing tank provides a usable volume of 381,900 gallons; therefore, the Trumansburg Road tank does not have sufficient storage volume to meet the Town's desired storage capacity. The Town should consider providing additional storage for the Bostwick Road service area to meet current water and fire demands and additional storage for the Trumansburg Road service area to meet the Town's desired storage capacity. Section 8 provides an evaluation of the West Hill system under projected future water demands, and improvement alternatives are discussed in more detail in Section 10.

Future Demands The Town anticipates additional development in the South Hill and West Hill water systems. The additional water demands from these potential developments were estimated and added to the calibrated models. The models were then used to analyze overall water system capacity and pressures, fire flow capacity, and suitability of the existing water storage tanks under the future demand conditions. The anticipated developments, calculated additional water demands, and analysis of the water systems under these higher water demands are discussed in more detail below. Future demands were determined based on two sources of information: (1) current development proposals under review by the Town, and (2) using the Town's Comprehensive Plan. The Town's Comprehensive Plan was used to determine how much development could occur in the undeveloped portions of the water service areas. Tax parcel data was used to establish lands that are already developed (if a tax parcel exists, it was assumed the land was already developed). Undeveloped lands were then compared with the existing water storage tank elevations to determine whether the undeveloped areas could be served by the existing tanks (at a minimum pressure of 35 psi). There is an area of land in the western portion of the West Hill service area that was not included in this analysis because it is above the elevation that can be served by the West Hill tank.Any undeveloped land that could be served by the existing tanks was then matched with the future land use designations in the Comprehensive Plan to establish the type of development that could occur. The total acreage of undeveloped land for each land use was calculated and then matched with the average development densities identified in the Town's Comprehensive Plan. The majority of the undeveloped land is designated for residential use, so this analysis provided a quantity of potential new residences that could be developed in each service area. In locations where commercial development was identified, the Town provided quantities for potential new commercial developments. Once quantities of new residential and commercial development were established, additional water demands were determined (discussed below) and were input into the model for analysis. Figures 8-1 and 8-2 show the undeveloped lands included in this analysis. It should be noted that this analysis for the quantity of future development is conservative, as it assumes that all undeveloped lands will be developed at the average densities identified in the Comprehensive Plan. Actual future development may be less. Many pieces of water infrastructure remain in service for 25 to 50 years. Therefore, it is important for municipalities to consider and balance short-term and potential long-term needs when designing and constructing water infrastructure. The hydraulic analysis provided herein under these future conditions, combined with the analysis under existing conditions (discussed in Sections 6 and 7)allows the Town to compare a range of demand conditions when planning for capital improvements. 8.1 Futurer Demands, South Hill The following potential additional developments were identified: GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 138 �fluVflll IIIIIIIIIIV�I IIWV�' 1. Chain Works District (CWD). This is envisioned as a mixed used development area, including residential and office uses, in the Northview/Danby service zone. It is anticipated the development in this area will include 471 apartments and 1 office. 2. 58 residential homes in the Northview/Danby service zone. 3. 466 residential homes in the Troy Road service zone. 4. 2,193 residential homes in the Ridgecrest service zone. Water demands were assigned to the CWD based on information provided by the Town. For the apartments and office in the CWD, an average daily water usage of 220 gpd per dwelling and 1,600 gpd per office were used. The CWD demand data provided by the Town included a peaking factor of 8 on the average day demands of 220 gpd and 1,600 gpd. The peaking factor of 8 was not included in the CWD additional demand. For consistency, a peaking factor of 1.7 was used for additional maximum day demand, and a peaking factor of 3.4 (two times maximum day demand) was used for additional peaking hour demand (see Table 8-2). Water demands were assigned to residential homes based on the latest industry studies on water usage. For single-family residences, an average daily water usage of 180 gpd per dwelling was used. This is based on the results of the latest Water Research Foundation report on water usage in North America.2 The procedure used to extract this average daily water usage is discussed in the previous modeling report by GHD, "East Hill Water System Improvements,"dated February 2017. Since water usage can vary significantly with geography and climate, the average water usage for four utilities from the study, located in the Northeastern U.S., was considered (Philadelphia, PA; New Haven, CT; Waterloo, Ontario; and Peel, Ontario). To determine an average water usage for the South Hill water system, the daily household water usage for the four utilities, which equaled 179 gpd per household and was rounded to 180 gpd, was averaged. On a per capita basis, the average water usage for the entire study was 95 gpd per capita and the average for the four Northeastern utilities was 65 gpd per capita. Table 8-1 summarizes the water usage for each development.

The resulting total water demands for the North view/Da nby, Troy Road, and Ridgecrest service areas are presented in Table 8-2. The model was then used to simulate the water system under the future average daily, maximum day, and peak hour demand conditions. The water system was evaluated based on system pressure and available fire flow for each of these demand conditions. The same evaluation criteria discussed in Section 6 was used to evaluate the system under future demand conditions. Table 8-2 Southill Summary of Modeled Demands, FutureConditions „ ' drt ;> t t � �1 8.2.1 Water Distribution System Pressures, Future Demands In the Northview/Danby service area, the additional demands had a negligible impact on water system pressures during average day conditions. Under peak hour conditions, there were some reductions in system pressures, but they remained above 35 psi for all customers in this service area. In the Troy Road service area, the additional demands caused some reductions in system pressures under average day conditions, but pressures remained above 35 psi for all customers. Under peak hour conditions, there were some additional reductions in system pressures in this service area. Pressures reduced below 35 psi for four customers. In the Ridgecrest service area, the additional demands caused some reductions in system pressure under average day conditions, but the number of customers with less than 35 psi of pressure did not increase. As discussed in Section 6.1.1, there are five customers in the Ridgecrest service area with pressures below 20 psi and seven customers with pressures below 35 psi under existing average day demands. Under peak hour conditions, there were additional reductions in system pressures in this service area. Pressures reduced below 35 psi for over 56 customers under future peak hour conditions in addition to the customers with pressures below 35 psi under existing demand conditions. Table 8-3 provides a summary of the system pressures under future demands. Figures 8-1 and 8-2 show the pressures across the distribution system under future average daily and future peak hour demand conditions, respectively.

Figure 8-3 provides a map of the distribution system hydrants, color coded based on their available fire flow. Table 8-6 is a summary of the available fire flows in the Northview/Danby, Troy Road, and Ridgecrest service areas.

Under future demand conditions, there is not a significant drop in available fire flows in the Northview/Danby service area. The number of hydrants in the Northview/Danby pressure zone that provide fire flows less than 500 gpm and the number of hydrants that provide fire flows greater than 1,500 gpm under future demand conditions are the same as existing demand conditions. There is a drop in available fire flows in the southwestern portion of the Troy Road service area under future demand conditions. Similar to existing demand conditions, there are no hydrants in the Troy Road pressure zone that provide fire flows greater than 1,500 gpm under future demand conditions. There are 16 additional hydrants, located in the southern portion of the Troy Road pressure zone that provide less than 500 gpm of fire flow under future demand conditions. Under future demand conditions, there is a slight drop in available fire flows throughout the Ridgecrest service area. Similar to existing demand conditions, there are no hydrants in the Ridgecrest pressure zone that provide fire flows greater than 1,500 gpm under future demand conditions. There is one additional hydrant located in the southeastern portion of the Ridgecrest pressure zone that provides less than 500 gpm of fire flow under future demand conditions.

Table 8-5 summarizes the water storage required for each pressure zone, based on water and fire demands and providing three days of storage. The table also shows the usable water storage available in the existing tanks. The existing Northview/Danby and Ridgecrest tanks provide enough storage to meet future water and fire demands with the PRV and pumps operational. The estimated water storage for the Northview/Danby and Ridgecrest tanks under these conditions is 167,600 and 238,100 gallons, respectively. The existing Troy Road tank does not provide enough storage to meet future water and fire demands with the pumps operational. The estimated water storage for the Troy Road tank under these conditions is 186,700 gallons and the usable storage available is 124,400 gallons. As stated previously, the Town also seeks to provide three days of storage in each tank under average daily demand conditions. The minimum water storage volume required for the Northview/Danby pressure zone to provide three days of storage under future average day demand conditions is 737,000 gallons. The existing tanks provide a usable volume of 1,015,200 gallons; therefore, the Northview/Danby tanks have sufficient storage volume to meet the Town's desired storage capacity. The minimum water storage volume required for the Troy Road pressure zone to provide three days of storage under future average day demand conditions is 332,900 gallons. The existing tank provides a usable volume of 124,400 gallons; therefore, the Troy Road tank does not have sufficient storage volume to meet the Town's desired storage capacity. The minimum water storage volume required for the Ridgecrest pressure zone to provide three days of storage under future average day demand conditions is 1,587,400 gallons. The existing tank provides a usable volume of 489,200 gallons; therefore, the Ridgecrest tank does not have sufficient storage volume to meet the Town's desired storage capacity. In summary, additional storage is needed to meet future water and fire demands in the Troy Road service area and to meet the Town's desired storage capacity in the Troy Road and Ridgecrest service areas.

Under peak hour conditions, there were some reductions in system pressures, but the pressures remained above 35 psi for all customers in the Bostwick Road service area. In the West Hill service area, the additional demands resulted in some reductions in system pressures under average day conditions and peak hour conditions. As discussed in Section 7.1.1, there are six customers in the West Hill service area with pressures below 35 psi under existing average day and peak hour demands. Pressures reduced below 35 psi for over 12 customers under future peak hour conditions in addition to the customers with pressures below 35 psi under existing demand conditions. In the Trumansburg Road service area, the additional demands had negligible impact on water system pressures during average day conditions. Under peak hour conditions, there were some reductions in system pressures, but the number of customers with less than 35 psi of pressure did not increase. As discussed in Section 7.1.1, there is one customer in the Trumansburg service area with pressure below 35 psi under existing average day and peak hour demands. Table 8-10 provides a summary of the system pressures under future demands.

The number of hydrants in the Bostwick Road service area that provide fire flows less than 500 gpm is the same under future demand conditions as existing demand conditions. The number of hydrants that provide fire flows greater than 1,500 gpm decreased from 22 hydrants under existing maximum day demand conditions to 9 hydrants under future maximum day demand conditions. There is a drop in available fire flows throughout the West Hill service area under future demand conditions. The number of hydrants in the West Hill service area that provide fire flows less than 500 gpm is the same under future demand conditions as existing demand conditions. The number of hydrants that provide fire flows greater than 1,500 gpm decreased from five hydrants under existing maximum day demand conditions to no hydrants under future maximum day demand conditions. Under future demand conditions, there is a slight drop in available fire flows in the Trumansburg Road service area. The number of hydrants in the Trumansburg Road pressure zone that provide fire flows less than 500 gpm and the number of hydrants that provide fire flows greater than 1,500 gpm under future demand conditions are the same as existing demand conditions. 8.4.3 Evaluation of Existing Water Storage The minimum required water storage for the Bostwick Road, West Hill, and Trumansburg Road service areas was calculated using the future water demands and the same criteria discussed in Section 7. Table 8-12 summarizes the water storage required for each pressure zone, based on water and fire demands and providing three days of storage. The table also shows the usable water storage available in the existing tanks.

Estimated water storage for the Bostwick Road tank under these conditions is 253,500 gallons. The usable storage available in the tank is 190,400 gallons. The existing West Hill and Trumansburg Road tanks provide enough storage to meet current water and fire demands with the pump and PRV operational. The estimated water storage for the West Hill and Trumansburg Road tanks under these conditions is 302,000 gallons and 176,700 gallons, respectively. As stated previously, the Town also seeks to provide three days of storage in each tank under average daily demand conditions. The minimum water storage volume required for the Bostwick Road pressure zone to provide three days of storage is 547,700 gallons. The existing tank provides a usable volume of 190,400 gallons; therefore, the Bostwick Road tank does not have sufficient storage volume to meet the Town's desired storage capacity under existing demands. The minimum water storage volume required for the West Hill pressure zone to provide three days of storage is 1,260,300 gallons. The existing tank provides a usable volume of 958,500 gallons; therefore, the West Hill tank does not have sufficient storage volume to meet the Town's desired storage capacity. The minimum water storage volume required for the Trumansburg Road pressure zone to provide three days of storage is 666,000 gallons. The existing tank provides a usable volume of 381,900 gallons; therefore, the Trumansburg Road tank does not have sufficient storage volume to meet the Town's desired storage capacity. Additional storage is needed to meet future water and fire demands in the Bostwick Road and West Hill service areas and to meet the Town's desired storage capacity in the Bostwick Road, West Hill, and Trumansburg Road service areas. Improvement alternatives are discussed in more detail in Section 10. 8.4.4 Summary of Findings Table 8-13 provides a summary of which critical water system goals were met for the existing Bostwick Road, West Hill, and Trumansburg Road water systems under existing and future demands. Section 10 discusses improvement alternatives to meet the needs of the existing and future water demands in the West Hill water system.

Improvement Alternatives, South Hill Capital improvements were identified based on analysis results of the existing system and the future system. Based on existing and future conditions in the system, improvements are suggested to ensure the following goals are met: 1. Provide a minimum pressure of 35 psi to customers in the Ridgecrest pressure zone under existing and future demands and to customers in the Troy Road pressure zone under future demands. 2. Provide a minimum available fire flow of 500 gpm for the Northview/Danby, Troy Road, and Ridgecrest pressure zones under existing and future demands. 3. Increase available fire flow to the minimum recommended 1,500 gpm for the maximum practical number of Town hydrants in the Northview/Danby, Troy Road, and Ridgecrest pressure zones under existing and future demands. 4. Increase the usable water storage in the Troy Road pressure zone to meet the minimum storage requirements under existing and future conditions and in the Ridgecrest pressure zone to meet the minimum storage requirements under future conditions. As noted in Section 8, the future demands used for this analysis are conservative. Improvement recommendations have been provided to meet the Town's water system goals under these conservative future demand conditions. When planning capital improvements for future demands, the Town should consider the amount of development actually anticipated over a time horizon that is appropriate for the infrastructure under consideration. Improvements were added to the water system model and their effects on the distribution system were evaluated and are discussed in the following sections. Improvement alternatives are prioritized based on the magnitude of their impact to the distribution system and meeting Department of Health requirements. Improvements are assigned a high, medium, or low priority. High priority improvements are required to meet minimum Department of Health standards or result in widespread improvements under existing conditions; medium priority improvements result in moderate improvements under existing conditions; and low priority improvements result in localized improvements or are improvements that are based on future demand. 9.1 Northview/DanbyPressure Under existing and future conditions, the Northview/Danby zone is able to meet minimum pressure requirements of 35 psi to all customers. Twenty-two hydrants provide more than 1,500 gpm of fire flow and 18 hydrants provide less than 1,500 gpm of fire flow, 2 of which provide less than 500 gpm. These two hydrants are located adjacent to the water storage tanks. 9.1.1 Northview/Danby Fire Flow Improvements (Existing Conditions) Fire flow is limited in the Northview/Danby pressure zone due to the size of the existing water mains. To improve fire flows in this pressure zone, Improvement Nos. 1 and 2 are presented for the GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 152 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' Town's consideration. In addition, the Town should consider removing the unused altitude valve on the water main from the Northview water storage tank. The locations of Improvement Nos. 1 and 2 are shown on Figure 9-1. Figure 9-2 presents the fire flow under existing conditions resulting from Improvement Nos. 1 and 2. As shown in Figure 9-2, Improvement Nos. 1 and 2 result in three hydrants providing less than 1,500 gpm of fire flow, one hydrant providing less than 1,000 gpm of fire flow, and no hydrants providing less than 500 gpm of fire flow. It is not practical for these four hydrants to provide more than 1,500 gpm of fire flow, and hydrants adjacent to these four hydrants provide sufficient fire flow. Improvement No. 1 This improvement includes switching the water mains on Northview Road from the Northview/ Danby pressure zone to the Troy Road pressure zone. This would be done by disconnecting the water main on Northview Road from the water main in the Northview/Danby pressure zone on Coddington Road, and installing a new 8-inch diameter water main (approximately 100 linear feet of pipe)to connect the water main on Northview Road to the water main in the Troy Road pressure zone on Coddington Road. This results in fire flow improvements along Northview Road. Since the impacts of this improvement are more localized than widespread, it is a medium priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. Improvement No. 2 This improvement consists of replacing the existing 6-inch water main in the Pennsylvania Avenue and Kendall Avenue neighborhoods with an 8-inch diameter water main (approximately 6,100 linear feet of pipe), which will result in fire flow improvements along Pennsylvania Avenue and Kendall Avenue. Since the impacts of this improvement are more localized than widespread, it is a medium priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. 9.1.2 Northview/Danby Improvements (Future Conditions) Under future conditions, with Improvement Nos. 1 and 2, there are three hydrants providing less than 1,500 gpm of fire flow, one hydrant providing less than 1,000 gpm of fire flow, and no hydrants providing less than 500 gpm of fire flow. Similar to existing conditions, it is not practical for these hydrants to provide more than 1,500 gpm of fire flow. For these reasons, no additional improvements are recommended for future conditions. Figure 9-3 presents the fire flows under future conditions resulting from Improvement Nos. 1 and 2. 9.2 TroyPressure Under existing conditions, the Troy Road zone is able to meet minimum pressure requirements of 35 psi to all customers. All hydrants provide less than 1,500 gpm of fire flow and six hydrants GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 153 P,�aamlP(11iSII�1N M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' provide less than 500 gpm of fire flow. The usable volume in the Troy Road water storage tank is sufficient to provide three days of storage under average daily demand conditions; however, it is not sufficient to meet current water and fire demands. The estimated volume to meet current water and fire demands for the Troy Road tank is 184,100 gallons and the usable volume available is 124,400 gallons. Under future conditions, there are more than four customers with less than 35 psi of pressure. All hydrants provide less than 1,500 gpm of fire flow and 22 hydrants provide less than 500 gpm of fire flow. The usable volume available in the Troy Road water storage tank is 124,400 gallons and is not sufficient to provide three days of storage under future average daily demand conditions or to meet future water and fire demands. The estimated volume to provide three days of storage under future average daily demand conditions and to meet future current water and fire demands is 332,900 and 206,900 gallons, respectively. 9.2.1 Troy Road Improvements (Existing Conditions) Fire Flow Improvements Fire flow is limited throughout the Troy Road pressure zone for the following reasons: 1. The existing water main from the Troy Road water storage tank is 8 inches in diameter. 2. The elevation of hydrants on Southwoods Drive, Eldridge Circle, and Old Gorge Road in relation to the elevation of the Troy Road water storage tank. Water pressures in this area are just above 35 psi of pressure and fire flows elsewhere in the Troy Road pressure zone cause these pressures to drop lower. The following is offered for the Town's consideration for improving fire flows throughout the Troy Road pressure zone. Figure 9-4 presents the locations of Improvement Nos. 1, 2A, and 2B. Figure 9-5 presents the fire flows under existing conditions resulting from Improvement Nos. 1 and 2A. Figure 9-6 presents the fire flows under existing conditions resulting from Improvement Nos. 1 and 2B. As shown in Figure 9-5, Improvement Nos. 1 and 2A result in two hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. As shown in Figure 9-6, Improvement Nos. 1 and 2B result in six hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. It is not practical for the hydrants noted above to provide more than 1,500 gpm of fire flow under these improvement alternatives. Improvement No. 1 This improvement includes switching the water mains on Southwoods Drive, Eldridge Circle, and Old Gorge Road from the Troy Road pressure zone to the Ridgecrest pressure zone since this neighborhood is the first to drop to an available pressure of 20 psi when there are fire flows in other parts of the Troy Road zone. This would be done by installing a new 8-inch diameter water main (approximately 1,800 linear feet of pipe)on East King Road between Southwoods Drive and Troy Road. Supplying this neighborhood from the Ridgecrest tank elevation would result in water pressures of over 150 psi along Southwoods Drive, Eldridge Circle, and Old GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 154 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' Gorge. This improvement subsequently includes installing a new PRV along the new 8-inch diameter water main. A PRV with a 60 psi setpoint would reduce water pressures in the neighborhood to below 100 psi of pressure. Fire flow and pressure improve along Southwoods Drive, Eldridge Circle, Old Gorge Road and along the south end of Coddington Road with this option. Since the existing fire flow is less than 500 gpm of fire flow, some customers in this neighborhood have low pressures (just above 35 psi of pressure), limiting fire flow in the rest of the zone and making it a high priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. Improvement No. 2A This improvement includes replacing the existing 8-inch diameter water main between the Troy Road water storage tank and Troy Road and the existing 8-inch diameter water main along Troy Road between the water main from the water storage tank and Coddington Road with a 12-inch diameter water main (approximately 5,000 linear feet of pipe). Increasing the size of these water mains results in widespread fire flow improvements in the Troy Road pressure zone. For this reason, it is a high priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. Improvement No. 2 This improvement includes replacing the existing 8-inch diameter water main between the Troy Road water storage tank and Troy Road with a 12-inch diameter water main (approximately 2,000 linear feet of pipe)and installing a PRV along the existing 8-inch diameter water main on East King Road between Southwoods Drive and Coddington Road. This is a modification and expansion of Improvement No. 1. This option results in widespread fire flow improvements in the Troy Road pressure zone and is a high priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. Water Storage Improvements The existing Troy Road water storage tank does not have sufficient storage to meet current water and fire demands. The estimated volume to meet current water and fire demands is 184,100 gallons and the usable volume available is 124,400 gallons. Improvement No. 3 for increasing water storage in the Troy Road pressure zone is presented below for the Town's consideration. Improvement No. 3 This improvement includes installing a manual PRV in the Troy Road Pump Station. Since the Ridgecrest pressure zone has surplus storage, the manual PRV would be utilized to backfeed GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 155 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' water from the Ridgecrest pressure zone to the Troy Road pressure zone when necessary. This improvement would provide the Troy Road service area with sufficient storage to meet the current water and fire demands as defined by the Ten-States Standards. For this reason, it is a high priority improvement. The location of Improvement No. 3 is shown on Figure 9-4. An opinion of probable cost is presented in Table 9-1. A detailed breakdown of costs is provided in Appendix A. 9.2.2 Troy Road Improvements (Future Conditions) Fire Flow Improvements Under future conditions with Improvement Nos. 1 and 2A, there are four hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. Under future conditions with Improvement Nos. 1 and 2B, there are six hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. Similar to existing conditions, it is not practical for the hydrants noted above to provide more than 1,500 gpm of fire flow. For these reasons, no additional improvements are recommended for future conditions. Figure 9-7 presents the fire flows under future conditions resulting from Improvement Nos. 1 and 2A, and Figure 9-8 presents the fire flows under future conditions resulting from Improvement Nos. 1 and 2B. Pressure Improvements Under future peak hour demand with Improvement Nos. 1 and 2A and Improvement Nos. 1 and 2B, there are no customers in the Troy Road service area with less than 35 psi of pressure. For this reason, no additional improvements are recommended for future conditions. Figure 9-9 presents water system pressures under future peak hour demand conditions resulting from Improvement Nos. 1 and 2A, and Figure 9-10 presents water system pressures under future peak hour demand conditions resulting from Improvement Nos. 1 and 2B. Water Storage Improvements If all of the development discussed in Section 8 were to occur, the usable volume in the Troy Road water storage tank would not be sufficient to provide three days of storage under future average daily demand conditions or to meet future water and fire demands. The estimated volume to provide three days of storage under future average daily demand conditions and to meet future water and fire demands is 332,900 and 206,900 gallons, respectively. The usable volume available in the Troy Road tank is 124,400 gallons. Since pressures under existing conditions in the Troy Road service area are adequate, new storage for the area can use the same elevations as the existing Troy Road tank. If all future development described in Section 8 were constructed in the Troy Road zone, an additional 209,000 gallons of water storage would be required. However, the Town should select a storage volume that is based on the actual amount of development anticipated. Alternatives for increasing water storage in the Troy Road pressure zone are presented below for the Town's consideration and are based on the development discussed in Section 8. GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 156 amlP(11i1I11pF W.4II ��fluVflll IIIIIIIIIIV�I WUM�' Improvement No. 4A This improvement includes installing a new water storage tank adjacent to the existing Troy Road water storage tank. The new tank would need to meet the following criteria: • Minimum water level under normal conditions - 1,912.50 feet • Minimum usable water storage above elevation 1,913.50 feet-209,000 gallons • Overflow elevation -As needed to meet the above two criteria This improvement would provide the Troy Road service area with sufficient storage to meet future water and fire demands as defined by the Ten-States Standards. It is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. Improvement No. 4 This improvement includes replacing the existing Troy Road water storage tank. The new water storage tank would need to meet the following criteria: • Minimum water level under normal conditions - 1,912.50 feet • Minimum usable water storage above elevation 1,913.50 feet-333,000 gallons This improvement would provide the Troy Road service area with sufficient storage to meet future water and fire demands and to provide three days of storage under future average daily demand conditions. It is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. 9.3 RidgecrestPressure Under existing peak hour conditions, there are five customers with less than 20 psi of pressure and eight customers with less than 35 psi of pressure, all located adjacent to the Ridgecrest water storage tank. All hydrants provide less than 1,500 gpm of fire flow and four hydrants provide less than 500 gpm of fire flow. The four hydrants are located adjacent to the water storage tank. The usable volume in the Ridgecrest water storage tank (excluding customers adjacent to the water storage tank) is sufficient to provide three days of storage under existing average daily demand conditions and to meet current water and fire demands. Under future conditions, there are 7 customers with less than 20 psi and more than 62 customers with less than 35 psi. All hydrants provide less than 1,500 gpm of fire flow and five hydrants provide less than 500 gpm of fire flow. Four of the hydrants are located adjacent to the water storage tank and one hydrant is located at a dead end on Chase Lane. The usable volume in the Ridgecrest water storage tank (excluding customers adjacent to the water storage tank) is sufficient to meet future water and fire demands but is not sufficient to provide three days of storage under future average daily demand conditions. The estimate volume to provide three days of storage under GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 157 P,�aamlP(11iSII�1N M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' future average daily demand conditions is 1,587,400 gallons and the usable volume available in the Ridgecrest water storage tank is 489,200 gallons. 9.3.1 Ridgecrest Improvements (Existing Conditions) Fire Flow Improvements Fire flow is limited throughout the Ridgecrest pressure zone due to water main size and the elevation of hydrants with respect to the Ridgecrest water storage tank. The following is offered for the Town's consideration for improving fire flow throughout the Ridgecrest pressure zone. Figure 9-11 presents the locations of Improvement Nos. 1A, 1 B, 2, 3, 4A, and 4B. Figures 9-12 through 9-15 present the fire flows under existing conditions resulting from the following Improvements: • Figure 9-12: Improvement Nos. 1A, 2, 3, and 4A • Figure 9-13: Improvement Nos. 1A, 2, 3, and 4B • Figure 9-14: Improvement Nos. 1 B, 2, 3, and 4A • Figure 9-15: Improvement Nos. 1 B, 2, 3, and 4B The four hydrants with less than 500 gpm adjacent to the Ridgecrest water storage tank are excluded from the fire flow analysis in Figures 9-12 through 9-15. Since there is less than 20 psi at these hydrant locations, it is assumed the customers near these hydrants will be removed from the pressure zone and connected to a separate booster pump. As shown in Figure 9-12, Improvement Nos. 1A, 2, 3, and 4A result in six hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. As shown in Figure 9-13, Improvement Nos. 1A, 2, 3, and 4B result in six hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. As shown in Figure 9-14, Improvement Nos. 1 B, 2, 3, and 4A result in three hydrants providing less than 1,500 gpm of fire flow, one hydrant providing less than 1,000 gpm of fire flow, and no hydrants providing less than 500 gpm of fire flow.As shown in Figure 9-15, Improvement Nos. 1 B, 2, 3, and 4B result in six hydrants providing less than 1,500 gpm of fire flow, one hydrant providing less than 1,000 gpm of fire flow, and no hydrants providing less than 500 gpm of fire flow. It is not practical for the hydrants noted above to provide more than 1,500 gpm of fire flow under these improvement alternatives. Improvement No. 1A This improvement includes replacing the existing 8-inch diameter water main on Ridgecrest Road between the Ridgecrest water storage tank and East King Road with a 12-inch diameter water main (approximately 3,000 linear feet of pipe). This would result in widespread fire flow improvements in the Ridgecrest pressure zone upstream of the West King PRVs. For this reason, it is a high priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 158 amlP(11iSII1NIIM.4 ��fluVflll IIIIIIIIIIV�I WUM�' Improvement No. 1 B This improvement includes installing a new 10-inch diameter water main between the Ridgecrest water storage tank and the water main on Chase Lane (approximately 1,800 linear feet of pipe). This would result in widespread fire flow improvements in the Ridgecrest pressure zone upstream of the West King PRVs, and for this reason, is a high priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. Improvement No. 2 This improvement includes installing a new 8-inch diameter water main on Troy Road between the existing 8-inch diameter water main on Troy Road and the existing 8-inch diameter water main on East King Road (approximately 1,500 linear feet of pipe). This would result in fire flow improvements on Troy Road, to the east of the Ridgecrest water storage tank. Since the impacts of this improvement are more localized than widespread, it is a medium priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. Improvement No. 3 This improvement includes replacing the following 8-inch diameter water mains with a 10-inch diameter water main (approximately 6,100 linear feet of pipe): • Existing water main on East King Road between Danby Road and the West King PRVs • Existing water main on Danby Road between East King Road and College Circle • Existing water main on College Circle This would result in widespread fire flow improvements along Danby Road, north of East King Road. For this reason, it is a medium priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. Improvement No. 4A This improvement includes installing a new 8-inch diameter water main between the existing water main on Larisa Lane and the existing water main on East King Road (approximately 2,300 linear feet of pipe). Installing this new water main would result in widespread fire flow improvements along Danby Road, south of East King Road. For this reason, it is a medium priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 159 P,�aamlP(11i1I11pF M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' Improvement No. 4B There is potential future development between Larisa Lane and East King Road which could necessitate installing the new water main described in Improvement No. 4A. If the Town plans to install this new water main in the near future, Improvement No. 4B is not recommended. However, if the water main proposed in Improvement No. 4A may not be installed for an extended period of time, Improvement No. 4B is an alternative that can provide similar improvement in fire flows. This improvement includes replacing the existing 8-inch diameter water mains on East King Road between Danby Road and the West King PRVs and on Danby Road between East King Road and approximately 750 feet north of Schickle Road with a 12-inch diameter water main (approximately 3,000 linear feet of pipe). Replacing these water mains would result in widespread fire flow improvements along Danby Road, south of East King Road and along Larisa Lane. For this reason, it is a medium priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. Pressure Improvements Improvement Nos. 1 A through 4B do not have a significant impact on pressure. With the improvements, there are still five customers with less than 20 psi of pressure and eight customers with less than 35 psi of pressure. Figure 9-16 presents the system pressures under existing peak hour demand resulting from Improvement Nos. 1 B, 2, 3, and 4A. To improve pressure to these customers, Improvement No. 5 is offered below for the Town's consideration. Figure 9-11 presents the location of Improvement No. 5. Improvement No. 5 This improvement includes installing a booster pump station for the customers adjacent to the Ridgecrest water storage tank. This would involve a small pump station, hydropneumatic tank, and water main to connect each of the customers. These customers have less than 35 psi of pressure. For this reason, this is a high priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. 9.3.2 Ridgecrest Improvements (Future Conditions) Fire Flow Improvements Figures 9-17 through 9-20 present the fire flows under future conditions resulting from the following improvements: • Figure 9-17: Improvement Nos. 1A, 2, 3, and 4A • Figure 9-18: Improvement Nos. 1A, 2, 3, and 4B • Figure 9-19: Improvement Nos.1 B, 2, 3, and 4A GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 160 ��fluVflll IIIIIIIIIIV�I IIWV��' • Figure 9-20: Improvement Nos.1 B, 2, 3, and 4B As shown in Figure 9-17, Improvement Nos. 1A, 2, 3, and 4A result in seven hydrants providing less than 1,500 gpm of fire flow, one hydrant providing less than 1,000 gpm of fire flow, and no hydrants providing less than 500 gpm of fire flow. As shown in Figure 9-18, Improvement Nos. 1A, 2, 3, and 4B result in 12 hydrants providing less than 1,500 gpm of fire flow, 1 hydrant providing less than 1,000 gpm of fire flow, and no hydrants providing less than 500 gpm of fire flow. As shown in Figure 9-19, Improvements Nos. 1 B, 2, 3, and 4A result in four hydrants providing less than 1,500 gpm of fire flow, one hydrant providing less than 1,000 gpm of fire flow, and no hydrants providing less than 500 gpm of fire flow.As shown in Figure 9-20, Improvements Nos. 1 B, 2, 3, and 4B result in nine hydrants providing less than 1,500 gpm of fire flow, one hydrant providing less than 1,000 gpm of fire flow, and no hydrants providing less than 500 gpm of fire flow. Similar to existing conditions, it is not practical for the hydrants noted above to provide more than 1,500 gpm of fire flow. For this reason, no additional improvements are recommended for future conditions. Pressure Improvements Under future peak hour demands with Improvement No. 5, there are no customers in the Ridgecrest service area with less than 35 psi of pressure. For this reason, no additional improvements are recommended for future conditions. Figure 9-21 presents the system pressures under future peak hour demand resulting from Improvement Nos. 1 B, 2, 3, and 4A. Water Storage Improvements If all of the development discussed in Section 8 were to occur, the existing Ridgecrest water storage tank would not have sufficient volume to provide three days of storage under future average daily demand conditions. The estimated volume to provide three days of storage under future average daily demand conditions is 1,587,400 gallons and the usable volume available in the Ridgecrest water storage tank is 489,200 gallons. Since the pressures under future conditions in the Ridgecrest service area with the above improvements are adequate, new storage for the Ridgecrest service area can use the same elevations as the existing Ridgecrest tank. If all future development described in Section 8 were constructed in the Ridgecrest zone, an additional 1,100,000 gallons of water storage would be required. However, the Town should select a storage volume that is based on the actual amount of development anticipated. Improvement No. 6 for increasing water storage in the Ridgecrest pressure zone is presented below for the Towns consideration and is based on the development discussed in Section 8. Improvement No. 6 This improvement includes installing a new water storage tank adjacent to the existing Ridgecrest water storage tank. The new tank would need to meet the following criteria: • Minimum water level under normal conditions - 1,416.50 feet • Minimum usable water storage above elevation 1,398 feet- 1,100,000 gallons • Overflow elevation -As needed to meet the above two criteria GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 161 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' This improvement would provide the Ridgecrest service area with sufficient storage to provide three days of storage under future average daily demand conditions. For this reason, it is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 9-1. A detailed breakdown of these costs is provided in Appendix A. 9.4 Southill System Additional Recommendations Under existing conditions and with the above improvements, there are several areas throughout the South Hill water system with high pressures (greater than 100 psi of pressure). To prevent these pressures from reaching the customer, all customer service lines are required to be equipped with PRVs. The presence of these valves ensures pressures within customers' plumbing are within accepted ranges according to Ten-States Standards. It is also recommended the Town obtain an ISO water system evaluation to determine the ISO needed fire flows specific to the South Hill water system to assist in prioritizing future water main replacements.

Improvement Alternatives, West Hill Capital improvements were identified based on analysis results of the existing system and the future system. Based on existing and future conditions in the system, improvements are suggested to ensure the following goals are met: 1. Provide a minimum pressure of 35 psi to customers in the West Hill and Trumansburg Road pressure zones under existing and future demands. 2. Provide a minimum available fire flow of 500 gpm for the Bostwick Road, West Hill, and Trumansburg Road pressure zones under existing and future demands. 3. Increase available fire flow to the minimum recommended 1,500 gpm for the maximum practical number of Town hydrants in the Bostwick Road, West Hill, and Trumansburg Road pressure zones under existing and future demands. 4. Increase the usable water storage in the Bostwick Road, West Hill, and Trumansburg Road pressure zones to meet the minimum storage requirements under existing and future conditions. As noted in Section 8, the future demands used for this analysis are conservative. Improvement recommendations have been provided to meet the Town's water system goals under these future demand conditions. When planning capital improvements for future demands, the Town should consider the amount of development actually anticipated over a time horizon that is appropriate for the infrastructure under consideration. Improvements were added to the water system model and their effects on the distribution system were evaluated and are discussed in the following sections. Improvement alternatives are prioritized based on the magnitude of their impact to the distribution system and meeting Department of Health requirements. Improvements are assigned a high, medium, or low priority. High priority improvements are required to meet minimum Department of Health standards or result in widespread improvements under existing conditions, medium priority improvements result in moderate improvements under existing conditions, and low priority improvements result in localized improvements or are improvements that are based on future demand. 10.1 BostwickPressure Under existing and future conditions, the Bostwick Road zone is able to meet minimum pressure requirements of 35 psi to all customers. Under existing and future conditions, the majority of hydrants provide less than 1,500 gpm of fire flow (but greater than 1,000 gpm of fire flow); one hydrant, located adjacent to the water storage tank, provides less than 500 gpm of fire flow. The usable volume in the Bostwick Road water storage tank is sufficient to provide three days of storage under existing average daily demand conditions but is not sufficient to meet current water and fire demands. The estimated volume to meet current water and fire demands is 207,300 gallons and the usable volume available in the Bostwick Road water storage tank is 190,400 gallons. GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 163 P,�aamlP(11iSII�1N W.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' The usable volume in the Bostwick Road water storage tank is not sufficient to meet future water and fire demands or to provide three days of storage under future average daily demand conditions. The estimated volume to meet future water and fire demands and to provide three days of storage under future average daily demand conditions is 253,500 and 547,700 gallons, respectively. The usable volume available in the Bostwick Road water storage tank is 190,400 gallons. 10.1.1 Bostwick Road Improvements (Existing Conditions) Fire Flow Improvements Fire flow is limited throughout the Bostwick Road pressure zone due to the size of some existing water mains. To improve fire flows, improvements are offered below for the Town's consideration. The locations of Improvement Nos. 1 and 2 are shown on Figure 10-1. Figure 10-2 presents the fire flows under existing conditions resulting from these improvements. As shown in Figure 10-2, Improvement Nos. 1 and 2 result in five hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. It is not practical for these hydrants to provide more than 1,500 gpm of fire flow. Improvement No. 1 This improvement includes replacing the existing 8-inch diameter water main on Bostwick Road between the Bostwick Road water storage tank and Seven Mile Drive with a 10-inch diameter water main (approximately 1,200 linear feet of pipe). Increasing the size of this water main results in widespread fire flow improvements throughout the Bostwick Road pressure zone. Existing fire flows are not substantially below 1,500 gpm, however, and only moderate improvements are needed. For this reason, it is a medium priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1 (found at the end of Section 10). A detailed breakdown of these costs is provided in Appendix B. Improvement No. 2 This improvement includes replacing the existing 8-inch diameter water main on Seven Mile Drive between Elmira Road and Bostwick Road with a 10-inch diameter water main (approximately 5,500 linear feet of pipe). Increasing the size of this water main results in fire flow improvements in the southwestern portion of the Bostwick Road pressure zone. Since the impacts of this improvement are more localized than widespread, it is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is provided in Appendix B. Water Storage Improvements The existing Bostwick Road water storage tank does not have sufficient volume to meet current water and fire demands. The estimated volume to meet current water and fire demands for the Bostwick Road tank is 207,300 gallons and the usable volume available in the tank is GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 164 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' 190,400 gallons. Improvement No. 3 for increasing water storage in the Bostwick Road pressure zone is presented for the Town's consideration. Improvement No. 3 This improvement includes utilizing the existing Stone Quarry CV/PRV to feed water from the Northview/Danby pressure zone to the Bostwick Road pressure zone when necessary. The Bostwick Road tank requires an additional 16,900 gallons of water to meet current water and fire demands. Under existing water and fire demands, the Northview/Danby pressure zone has 862,600 gallons of excess storage. Utilizing the existing Stone Quarry CV/PRV would provide the Bostwick Road service area with sufficient storage to meet the current water and fire demands as defined by the Ten-States Standards. For this reason, it is a high priority improvement. This improvement involves operation of the existing system and does not require construction; therefore, it is considered a no cost improvement. 10.1.2 Bostwick Road Improvements (Future Conditions) Fire Flow Improvements Figure 10-3 presents the fire flows under future conditions resulting from Improvement Nos. 1 and 2. As shown in Figure 10-3, these improvements result in nine hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. It is not practical for these hydrants to provide more than 1,500 gpm of fire flow. For this reason, no additional improvements are recommended for future conditions. Water Storage Improvements If all of the development discussed in Section 8 were to occur, the usable volume in the Bostwick Road water storage tank would not be sufficient to meet future water and fire demands or to provide three days of storage under future average daily demand conditions. The estimated volume to meet future water and fire demands and to provide three days of storage under future average daily demand conditions is 253,500 and 547,700 gallons, respectively. The usable volume available in the Bostwick Road water storage tank is 190,400 gallons. Improvement No. 4 for increasing water storage in the Bostwick Road pressure zone is presented for the Town's consideration. Improvement No. 4 This improvement includes utilizing the existing Stone Quarry CV/PRV to feed water from the Northview/Danby pressure zone to the Bostwick Road pressure zone when necessary. If all future development described in Section 8 were constructed in the Bostwick Road zone, an additional 358,000 gallons of water storage would be required. Under future water and fire demands, the Northview/Danby pressure zone has 847,600 gallons of excess storage. Utilizing the existing Stone Quarry CV/PRV would provide the Bostwick Road service area with sufficient storage to meet the future water and fire demands as defined by the Ten-States Standards. For this reason, it is a low priority improvement. GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 165 ��fluVflll IIIIIIIIIIV�I IIWV��' This improvement involves operation of the existing system and does not require construction; therefore, it is considered a no cost improvement. 10.2 West Hill Pressure Under existing conditions, there are six customers with less than 35 psi of pressure. The majority of hydrants provide less than 1,500 gpm of fire flow and four hydrants provide less than 500 gpm of fire flow; however, these four hydrants are located adjacent to the water storage tank. The usable volume in the West Hill water storage tank is sufficient to provide three days of storage under average daily demand conditions and to meet current water and fire demands. Under future conditions, there are more than 12 customers with less than 35 psi of pressure. All hydrants provide less than 1,500 gpm of fire flow and four hydrants provide less than 500 gpm of fire flow; however, these four hydrants are located adjacent to the water storage tank. The usable water volume in the West Hill water storage tank is sufficient to meet future water and fire demands but is not sufficient to provide three days of storage under future average daily demand conditions. The estimated volume to provide three days of storage under future average daily demand conditions is 1,260,300 gallons. The usable volume available in the West Hill water storage tank is 958,500 gallons. 10.2.1 West Hill Improvements (Existing Conditions) Fire Flow Improvements Fire flow is limited throughout the West Hill pressure zone due to the size of the existing water mains and customers with low water pressures under normal conditions. To improve fire flows throughout the West Hill pressure zone, improvements are offered below for the Town's consideration. The locations of Improvement Nos. 1 through 6 are shown on Figure 10-4. Figure 10-5 presents the fire flows under existing conditions resulting from these improvements. As shown in Figure 10-5, Improvement Nos. 1 through 6 result in 16 hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. It is not practical for these hydrants to provide more than 1,500 gpm of fire flow. For this reason, Improvement No. 6 provides sufficient fire flow to a portion of the area in which the 16 hydrants are located. Improvement No. 1 This improvement consists of replacing the existing 10-inch diameter water main between the West Hill water storage tank and the water main on West Haven Road with 14-inch diameter water main (approximately 1,750 linear feet of pipe). Increasing the size of this water main results in widespread fire flow improvements in the West Hill pressure zone. For this reason, it is a high priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is presented in Appendix B. GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 166 ��fluVflll IIIIIIIIIIV�I IIWV��' Improvement No. 2 This improvement includes installing a booster pump station for the two customers located at the northern end of Valley View Road. These customers have less than 35 psi of pressure and less than 500 gpm of available fire flow under existing conditions. For this reason, this is a high priority improvement. If a new pressure zone were implemented west of the West Hill system to serve future development, the customers located at the northern end of the Valley View Road could be included in the new zone. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is presented in Appendix B. Improvement No. 3 This improvement includes installing a new PRV along the existing 8-inch diameter water main between Conifer Circle and Hector Street in addition to the existing Oakwood PRV off Oakwood Lane. The new PRV should have a 90 psi setpoint. Installing a new PRV results in fire flow improvements throughout the eastern portion of the West Hill pressure zone (hydrants located in the City). Since the impacts of these improvements are widespread in the eastern portion of the pressure zone, it is a high priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is presented in Appendix B. Improvement No. 4 This improvement consists of switching three existing hydrants on Trumansburg Road between Candlewyck Drive and Brookfield Road from the West Hill pressure zone to the Trumansburg Road pressure zone by opening and closing existing isolation valves. Switching the pressure zone of these hydrants improves fire flow in the three hydrants. Since the impacts of this improvement are more localized than widespread, it is a low priority improvement. This improvement involves operation of the existing system and does not require construction; therefore, it is considered a no cost improvement. Improvement No. 5 This improvement consists of replacing the existing 6-inch diameter water main on Trumansburg Road between Candlewyck Drive and Brookfield Road with an 8-inch diameter water main (approximately 2,200 linear feet of pipe). Increasing the size of this water main improves fire flow to two hydrants in the eastern portion of the West Hill pressure zone (hydrants located in the City). Since the impacts of this improvement are more localized than widespread, it is a low priority improvement. Improvement No. 6 This improvement includes installing a new hydrant on the existing water main on Hayts Road (County Road 139) northwest of West Hill Circle. The hydrant would be installed in the Trumansburg Road pressure zone on the existing water main between the Trumansburg Road GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 167 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' water storage tank and Trumansburg Road. The hydrant could be utilized to provide fire flow to the West Hill Circle neighborhood (it is not practical for hydrants in this neighborhood which are served off of the West Hill tank to provide greater than 1,500 gpm of fire flow). Since the impacts of this improvement are more localized than widespread, it is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is presented in Appendix B. Pressure Improvements Improvement Nos. 1 and 2 result in all customers in the West Hill pressure zone having at least 35 psi of pressure under existing conditions. For this reason, no additional improvements are recommended. Figure 10-6 presents the system pressures under existing peak hour demand resulting from Improvement Nos. 1 through 6. 10.2.2 West Hill Improvements (Future Conditions) Fire Flow Improvements Under future conditions with Improvement Nos. 1 through 6, there are 16 hydrants providing less than 1,500 gpm of fire flow and no hydrants providing less than 500 gpm of fire flow. Due to their elevation and location, it is not practical for these hydrants to provide more than 1,500 gpm of fire flow. For this reason, no additional improvements are recommended for future conditions. Figure 10-7 presents the fire flows under future conditions resulting from Improvement Nos. 1 through 6. Pressure Improvements Under future peak hour demand with Improvement Nos. 1 through 6, there are more than eight customers in the West Hill service area with less than 35 psi of pressure. To improve pressure to these customers, water storage improvements are provided below for the Town's consideration. Figure 10-8 presents the system pressures under future peak hour demand resulting from Improvement Nos. 1 through 6. Water Storage Improvements If all of the development discussed in Section 8 were to occur, then the existing West Hill water storage tank would not have sufficient storage to provide three days of storage under future average daily demand conditions. The estimated volume to provide three days of storage under future average daily demand conditions is 1,260,300 gallons and the usable volume available in the West Hill water storage tank is 958,500 gallons. Since pressures under future conditions in the West Hill service area are not adequate, new storage for the West Hill service area should use a greater elevation than the existing West Hill water storage tank. If all future development described in Section 8 were constructed in the West Hill zone, an additional 302,000 gallons of water storage would be required. However, the Town should GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 168 P,�aamlP(11i1I11pF W.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' select a storage volume that is based on the actual amount of development anticipated. Alternatives for increasing water storage in the West Hill pressure zone are presented below for the Town's consideration and are based on the development discussed in Section 8. Improvement No. 7A This improvement includes installing a new water storage tank adjacent to the existing West Hill water storage tank. The new water storage tank would need to meet the following criteria: • Minimum water level under normal conditions - 1,080 feet • Minimum usable water storage above elevation 1,081 feet- 302,000 gallons • Overflow elevation -As needed to meet the above two criteria This improvement would provide the West Hill service area with sufficient storage to meet the future water and fire demands as defined by the Ten-States Standards. For this reason, it is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is provided in Appendix B. Improvement No. 7 This improvement includes replacing the existing West Hill water storage tank. The new tank would need to meet the following criterial • Minimum water level under normal conditions - 1,080 feet • Minimum usable water storage above elevation 1,081 feet- 1,300,000 gallons • Overflow elevation -As needed to meet the above two criteria This improvement would provide the West Hill service area with sufficient storage to meet the future water and fire demands as defined by the Ten-States Standards. For this reason, it is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is provided in Appendix B. 10.3 Trumansburg Road Pressure Zone Under existing and future conditions, there is one customer with less than 35 psi of pressure. All hydrants provide less than 1,500 gpm of fire flow and two hydrants provide less than 500 gpm of fire flow; however, these two hydrants are located adjacent to the water storage tank. The usable volume in the Trumansburg Road water storage tank is sufficient to meet current water and fire demands but is not sufficient to provide three days of storage under existing average daily demand conditions. The estimated volume to provide three days of storage under existing average daily demand conditions is 421,200 gallons and the usable volume available in the Trumansburg Road water storage tank is 337,800 gallons.

The estimated volume to provide three days of storage under existing future daily demand conditions is 666,000 gallons and the usable volume available in the Trumansburg Road water storage tank is 337,800 gallons. 10.3.1 Trumansburg Road Improvements (Existing Conditions) Fire Flow Improvements Fire flow is limited throughout the Trumansburg Road pressure zone due to the size of the existing water mains. To improve fire flows throughout the Trumansburg Road pressure zone, improvements are offered below for the Town's consideration. The locations of Improvement Nos. 1 and 2 are shown on Figure 10-9. Figure 10-10 presents the fire flows under existing conditions from these improvements. As shown in Figure 10-10, Improvement Nos. 1 and 2 result in no hydrants with less than 1,500 gpm of fire flow. Improvement No. 1 This improvement consists of replacing the existing 10-inch diameter water main along Hayts Road (County Road 139) between the Trumansburg Road storage tank and Trumansburg Road with 12-inch diameter water main (approximately 1,300 linear feet of pipe). Increasing the size of this water main results in widespread fire flow improvements in the Trumansburg Road pressure zone. However, existing fire flows are not substantially below 1,500 gpm of fire flow and only moderate improvements are needed. For this reason, it is a medium priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is presented in Appendix B. Improvement No. 2 This improvement consists of replacing the existing 8-inch diameter water main along Dubois Road between Trumansburg Road and Woolf Lane with 10-inch diameter water main (approximately 3,700 linear feet of pipe). Increasing the size of this water main results in fire flow improvements in the northern portion of the Trumansburg Road pressure zone. Since the impacts of this improvements are localized in the northern portion of the pressure zone, it is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is presented in Appendix B. Pressure Improvements Under existing peak hour demands, there is one customer with less than 35 psi of pressure. To improve pressure to this customer, Improvement No. 3 is offered below for the Town's consideration. GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 170 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' The location of Improvement No. 3 is shown in Figure 10-9. Figure 10-11 presents the system pressures under current peak hour demands resulting from Improvement Nos. 1 through 3. Improvement No. 3 This improvement consists of switching one customer on Trumansburg Road just south of Dubois Road from the Trumansburg Road pressure zone to the Van Dorns pressure zone by opening and closing existing isolation valves, installing a new isolation valve, and installing approximately 500 linear feet of new 10-inch diameter water main. Switching the pressure zone of this customer provides greater than 35 psi of pressure. Since the existing customer has less than 35 psi of pressure, it is a high priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is presented in Appendix B. Water Storage Improvements The existing Trumansburg Road water storage tank does not have sufficient volume to provide three days of storage under existing average daily demand conditions. The estimated volume to provide three days of storage under existing average daily demand conditions is 421,200 gallons and the usable volume available in the Trumansburg Road water storage tank is 337,800 gallons. Improvement No. 4 for increasing water storage in the Trumansburg Road pressure zone is presented below for the Town's consideration. Improvement No. 4 This improvement includes using the existing Trumansburg Road PRV to feed water from the West Hill pressure zone to the Trumansburg Road pressure zone when necessary. This improvement would provide the Trumansburg Road service area with sufficient storage to meet the current water and fire demands as defined by the Ten-States Standards. For this reason, it is a high priority improvement. This improvement utilizes the existing system and does not require construction; therefore, it is considered a no cost improvement. 10.3.2 Trumansburg Improvements (Future Conditions) Fire Flow Improvements Under future conditions with Improvement Nos. 1 through 3, there are no hydrants providing less than 1,500 gpm of fire flow. For this reason, no additional improvements are recommended for future conditions. Figure 10-12 presents the fire flows under future conditions resulting from Improvement Nos. 1 through 3. Pressure Improvements Under future peak hour demands with Improvement Nos. 1 through 3, there are no customers in the Trumansburg Road service area with less than 35 psi of pressure. For this reason, no additional GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 171 P,�aamlP(11i1I110 m.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' improvements are recommended for future conditions. Figure 10-13 presents system pressures under future peak hour demand resulting from Improvement Nos. 1 through 3. Water Storage Improvements The usable volume in the Trumansburg Road water storage tank is not sufficient to provide three days of storage under future average daily demand conditions. The estimated volume to provide three days of storage under existing future daily demand conditions is 666,000 gallons and the usable volume available in the Trumansburg Road water storage tank is 337,800 gallons. Since pressures under existing conditions in the Trumansburg Road service area are adequate with Improvement No. 3 described above, new storage for the Trumansburg Road service area can use the same elevations as the existing Trumansburg Road tank. If all future development described in Section 8 were constructed in the Trumansburg Road zone, an additional 330,000 gallons of water storage would be required. However, the Town should select a storage volume that is based on the actual amount of development anticipated. Alternatives for increasing water storage in the West Hill pressure zone are presented below for the Town's consideration and are based on the development discussed in Section 8. Improvement No. 5A This improvement includes installing a new water storage tank adjacent to the existing Trumansburg Road water storage tank. The new water storage tank would need to meet the following criteria: • Minimum water level under normal conditions - 1,003.00 feet • Minimum usable water storage above elevation 1,015.00 feet-330,000 gallons • Overflow elevation -As needed to meet the above two criteria This improvement would provide the Trumansburg Road service area with sufficient storage to provide three days of storage under future average daily demand conditions. For this reason, it is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is provided in Appendix B. Improvement No. This improvement includes replacing the existing Trumansburg Road water storage tank. The new tank would need to meet the following criteria: • Minimum water level under normal conditions - 1,003.00 feet • Minimum usable water storage above elevation 1,015.00 feet-670,000 gallons This improvement would provide the Trumansburg Road service area with sufficient storage to provide three days of storage under future average daily demand conditions. For this reason, it is a low priority improvement. An opinion of probable cost for this improvement is presented in Table 10-1. A detailed breakdown of these costs is provided in Appendix B. GHD I South Hill and West Hill Water Systems Improvements,Town of Ithaca, NY- 11144172.1 172 P,�aamlP(11i1I110 M.4 ��fluVflll IIIIIIIIIIV�I IIWUM�' 10.4 West Hill System Additional Recommendations In addition to the above improvements, it is recommended that all 4-inch diameter water mains in the West Hill water system be replaced with 8-inch diameter water mains. An opinion of probable cost is presented in Table 10-1. A detailed breakdown of these costs is provided in Appendix B. Under existing conditions and with the above improvements, there are several areas throughout the West Hill water system with high pressures (greater than 100 psi of pressure). To prevent these pressures from reaching the customer, all customer service lines are required to be equipped with PRVs.
