Consider Adjournment Study Sessionof the Ithaca Town Board Monday, February 27, 2012 at 4:30 p.m. 215 North Tioga Street, Ithaca, NY 14850 Minutes Present : Herb Engman, Supervisor; Board Members – Pat Leary, Tee-Ann Hunter, Rich DePaolo, Eric Levine and Nahmin Horwitz Absent – Bill Goodman Call to Order Meeting was called to order at 4:35pm Review Draft Agenda for Regular Meeting There were no questions or comments Town Hall Indoor Air Quality Report –Paul Tranchell Attachment #1 Mr. Tranchell summarized his written report. Ms. Leary had questions and concerns about taking away the staff’s ability to regulate their areas and Mr. Weber and Mr. Tranchell explained that the two systems are fighting each other and the problems associated with HVAC in buildings of this age with high ceilings and open floor plans. There were a number of recommendations, some costly, some not and Mr. Weber went on to say that some of the recommendations will be done in-house and maintenance will be spread out. We will see what effect those changes have and go from there. We are not tied into using O’Brien for any of the recommendations and the Town will have to decide future steps, if needed, later. The key is the building is within normal parameters and not a “sick” building. Mr. DePaolo asked about the VOCs found and Mr. Tranchell stated that there were very few and the pollutant inventory was organic and not to anywhere near a level of concern. Most issues seem to be focused on the ventilation and the systems battling each other. Town Official’s Reports Smart Work Update – Mr. Bates explained that the department worked with a group applying Smart Work program which is a review process of procedures. The department and facilitator focused on the building permit process and identified issues and solutions to try. Mr. Bates gave several examples and some discussion on each followed. Improve department image and consumer friendliness and get everyone on the same page and using the same standards. There will be a visual whiteboard up front that will help educate/show the customers how many permits are in front of them etc. and some other customer education efforts so they understand what the department does. TBS 2/27/2012 Page 2 of 7 The Department has set goals and initiated some changes that will involve other staff also such as a “do not disturb” period that must be respected by all and taking applications only when they are complete etc. Mr. Engman added that he met with the department and emphasized that they should bring any recommendations for changing our laws or zoning to help them; that the Board is open to change and willing to listen and review. We are not here to chastise the public, but to help the public get their projects done. It is a balancing act. Public Works Department Collaboration Program Ms. Drake explained that this came out of Personnel Committee and ERC and will be personal development for public works to help deal with all the changes of the past few years in Board, staff, unionization, etc and to talk about their issues and concerns. This will be followed by small focus groups. Bob Blenn is the facilitator who the group is familiar with and seems to like. She stressed to staff that the success of the program depends on them and although no one gets to choose their boss or people they work with, you do have to figure out how to work with them on a professional level. Mr. Horwitz asked if she was satisfied that staff understands there is a process and chain of command that they can voice their concerns/complaints to and she said she was. Report from the Association of Towns Rich DePaolo – Thought that the overall takeaway was that the workshops and classes are geared towards municipalities that need much more help than us; we seem to be ahead of many. In general it underscored his impression that we are in good shape. Herb Engman – Tried to attend the unusual topics because he is familiar with gas drilling. He went to one workshop on annexation because during some discussions with former leaders, the thought was tossed at him that it could happen. He found out that when one municipality owns land in an adjacent municipality it is easy to annex, both municipal boards would have to agree, but then it could happen and example is Six Mile Creek. Forcible annexation, on the other hand, is virtually impossible. There is a requirement for a vote of the residents on both sides and it is complicated and expensive. He also attended a workshop on the 2% tax cap and some of the effects on collective bargaining that he got some tidbits from. Tee-Ann Hunter – Reported that she was glad to see that the association is coming to terms with the fire protection issue and keeping the volunteer departments going etc. She added that the workshop did raise some questions in her mind, especially after the recent report from the Commissioner. Emergency response seems to make up more than 85% of the calls and she would like to understand why and exactly what we are mandated to provide. Discussion on billing for these services and how or why we don’t. Discussion on response times followed. Adopted 3/12/2012 TBS 2/27/2012 Page 3 of 7 Eric Levine – Disappointed in the variety offered and thought attendance was down. He did go to a workshop on Human Resources which he will forward to the board and anther one called Changing Landscape of Economic Development and Planning which was a presentation by the Supervisor of Chester, NY and what he did to make his town grow while others didn’t. Not that they all would fit us, but he took notes that he will send out. He also went to the Open Meetings workshop and also met with a member of the Association of Fire Districts who would be willing to talk to the board or fire committee. Report from Committees Budget Committee – Eric Levine reported that they discussed health insurance contribution and Mr. Solvig’s report which he has already given to the Board. Codes and Ordinances Committee – Herb Engman reported for Bill Goodman that the stream setback law will be coming to the Board to have a public hearing set and next big item is revising the sign law. Comprehensive Plan Committee – Herb Engman report that they are now in the difficult part of the planning; deciding which areas of the town should be used for what type of development or use. For example, the Ithaca Country Club land; it’s a business now, but what if is goes out of business? What should the allowed uses be? The thinking is to have a portion for residential and a portion reserved for open space. What about the triangle near Troy Road; what might happen there? It is intensive development now, with powerlines but what else? Then there is the Emerson property which should be a special area that doesn’t fall into the norm similar to the golf course. Planning Committee – Rich DePaolo reported that Tom Mank is scheduled to present the revised traffic models at the next meeting. They talked about the county RFP for the Biggs Property which is on tonight’s agenda. He added that he, Susan and Tee-Ann met with Ms. Cornish today and they thought it would be nice to see a larger land-use map that incorporates the Town and City ideas especially around the borders and to schedule a joint planning group of the Town and City for the County to present their plan(s) for the Biggs property to. The tentative th date is March 14 at City Hall. Tee-Ann Hunter added that the City has been doing a lot of outreach on their Comprehensive Plan and they have a survey online and they are seeking comments from commuters, non-city residents, etc. Personnel and Organization Committee – Herb Engman reported for Bill Goodman that the new committee has not met yet, but discussions on health insurance premium contributions is on the agenda. Public Works Committee – No February meeting. March meeting they will continue reviewing road preservation law and they decided to use the County model instead of the Danby model. Adopted 3/12/2012 TBS 2/27/2012 Page 4 of 7 Records Management Advisory Board (RMAB) – Paulette Terwilliger reported that they had their first meeting today, and reviewed what was accomplished last year and starting reviewing procedures from Planning, Codes and Town Clerk on some record series for duplication and efficiency. AdHoc Committees Fire Service – Eric Levine reported that Herb Engman is setting up a meeting with the Varna Fire Department since they are close to the Town to see how they operate. Rich DePaolo asked if there has been any talk of joint-governance similar to the IAWWTP and Herb Engman responded that he had a very brief conversation with the Mayor about that and he seems a lot more open about all possibilities. Intermunicipal Committees th Recreation Partnership – Eric Levine reported that the Annual Meeting is March 28 at the Human Services building and Herb Engman added that the 5 year contract is coming up so TCCOG has been talking about it and hopefully the participating municipalities will continue and maybe have the Town of Lansing join. With budgets being what they are, the County, the City and the Town have to commit to hold it together. Tee-Ann Hunter added that the Recreation Services survey being prepared in conjunction with SUNY Cortland College should be going out in the next week or so. In May the students will present their results. Discussion Items (Audio not available) Climate Smart Showcase Communities RFP Discussion The Planning Department Memo regarding the RFP was discussed. (Attachment #2) The assumption is the RFP is going to go out with this location (Bigg’s Property) so although we have made it very clear that we do not believe this is a good location, we should comment on the plans. There was a lot of discussion regarding the limited parking being shown and how far it was from the residences. Ms. Leary thought it was discriminating against older people or a group of people who are unable to easily traverse that distance and Mr. Engman felt that if they were planning a low vehicle development, that group of people would not be interested in it or not the target group for this type of community. Discussion followed. The Board asked Ms. Ritter to soften the comments regarding distance to the parking and to put the recommendations from the memo into resolution form to be considered at the March meeting.

Support for TCAT Transit TB RESOLUTION No. 2012- 045: In Support of Maintaining Dedicated Funding for Public Transportation Funding in the Surface Transportation Legislation WHEREAS, provisions in the federal American Energy and Infrastructure Jobs Financing Act of 2012 (H.B. 7) would eliminate dedicated federal fuels taxes for public transit and create long- term uncertainty for public transportation funding for the first time in three decades, and WHEREAS, since 1983, nearly half of all public transportation funding has been provided from the federal motor fuels tax dedicated to the Highway Trust Fund, and WHEREAS, this funding structure has successfully provided highway and transit programs with secure, dedicated revenues and has allowed Tompkins Consolidated Area Transit, Inc. (TCAT, Inc.) and public transit systems across the country to create jobs, including those for the bus manufacturing industry in New York State, and WHEREAS, under these provisions in H.B. 7, public transit funding would receive a one-time appropriation with no funding for public transportation after 2016 and would create uncertainty for TCAT, and WHEREAS, the absence of predictable and dedicated funding would have consequences for the thousands of people in Tompkins County and the millions of people all over the United States who rely on public transit. WHEREAS, U.S. Rep. Jerrold Nadler, D-NY, the senior northeastern member of the U.S. House Transportation and Infrastructure Committee, offered a bipartisan amendment to H.R. 7 that would restore transit funding, and, WHEREAS, the Nadler amendment and all other efforts by other Congressional leaders and the White House to preserve public transit funding is critically important as TCAT looks to expand capacity during record ridership of nearly 4 million annual trips. Adopted 3/12/2012 TBS 2/27/2012Page 7 of 7\ NOW, THEREFORE, be it RESOLVED that the Town of Ithaca strongly opposes any current orfuture proposals that would eliminate dedicated funding for public transit and applauds all effortsdemonstrated thus far to preserve such funding going forward.MOVED: Rich DePaolo SECONDED: Pat LearyVOTE: Ayes - Engman, Leary, Hunter, Levine, Horwitz and DePaoloConsider Adjournment Meeting adjourned upon motion and a second at 7:17 p.m. Respectfi^ submitted by r .

PROJECT BACKGROUND The Town of Ithaca purchased the existing Post Office building on the corner of Buffalo and Tioga Streets in the City of Ithaca in 2000. This building was originally constructed in 1910 and included an addition constructed in 1935. The original building was again renovated when the Town moved its offices into the building in the Fall of 2001, at which time the building became known as the Town Hall. As part of the renovation project, the air handling system was upgraded with the old boiler and radiant heating remaining in place. The purpose of this study is to assess the current indoor air quality in the Town Hall and to develop strategies aimed at improving indoor air quality by modifying the HVAC system to achieve optimum energy efficiency and occupant health and comfort. r > f % f s II FINAL; February 22,2012 l:\lthaca-T.6449\48281.Town-Of-lthaca\Docs\Reports\Town Of Ithaca lAQ FINALdoc QaBRIENGGERE TOWN OF ITHACA I INDOOR AIR QUALITY REPORT 2. PROJECT METHODOLOGY The following describes the methods used to assess indoor air quality and evaluate the HVAC system. 2,1 EXISTING TOWN HALL AIR QUALITY Indoor air quality was assessed through an employee survey, pollutant source inventory, and air sampling as described below. 2.1.1 Employee Survey An online survey of indoor air quality was conducted using an Occupant Health and Comfort Questionnaire developed for this assessment that was based on the "Indoor Air Quality-A Systems Approach" published by the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA). The survey was made available on line to all employees in the Town Hall offices. Summarized results are listed In Attachment 1. Face to face interviews were performed for nine (9] employees selected to represent the range of survey responses (from no complaints to several complaints). Interviews were performed using the "Occupant Interview" approach found in SMACNA document referenced above. The surveys are located in Attachment 2. 2.1.2 Pollutant Source Inventory In addition a Pollutant Source Inventory, from the same reference, was competed. The inventory is in Attachments. 2.1.3 Air Sampling The O'Brien & Gere industrial hygiene technician conducted measurements for carbon dioxide, carbon monoxide, relative humidity, and temperature in 5 rooms identified through the sampling plan development Sample locations are identified in Attachment 4. The sample strategy was finalized by Paul Tranchell, CIH after the completion of the interviews and the pollutant source inventory. Additional measurements and sampling were performed for VOCs (Volatile Organic Compounds as measured photoionization detector), Dust (PMIO), and Fungi. Carbon Dioxide Carbon dioxide, a gas normally found in outside air at concentrations ranging from 200 to 500 parts per million (ppm), is used in indoor air quality studies as an indicator gas. Carbon dioxide was chosen as a measurement parameter for this project because humans exhale carbon dioxide, which has the potential to build up in concentration over the course of a day. According to the American Society of Heating, Refrigerating, and Air Conditioning Engineers, Inc. (ASHRAE) Standard 62-2007, Ventilation for Acceptable Indoor Air Quality (ASHRAE 62-2007), a properly designed ventilation system should maintain a steady-state carbon dioxide level in a space no greater than 700 ppm above outdoor levels. ASHRAE has recommended this limit for carbon dioxide to satisfy comfort criteria with respect to human bioeffluents (body odor). If a ventilation system is not capable of maintaining a carbon dioxide concentration less than 700 ppm above outdoor level, then the system may also not be capable of providing sufficient outside air to remove other airborne substances produced by furnishings, work activities, and supplies. OSHA has established a Permissible Exposure Level (PEL) of 5,000 ppm for carbon dioxide. Carbon dioxide monitoring was performed using a TSI 8554 Q-Trak Plus Indoor Air Quality Monitor (Q-Trak monitor). Measurements were collected periodically at the five lAQ locations throughout the Town Hall for over approximately an 8-hour period on December 6,2011. Approximate sampling locations are provided in Attachment 4 of this report. The carbon dioxide measurements are also provided in Attachment 5. Carbon Monoxide Carbon monoxide is considered to be the most dangerous product of internal combustion. It is normally found in indoor air at levels ranging from 1 to 2 ppm. Carbon monoxide was chosen as a parameter in this survey to evaluate whether combustion sources, such as smoking or internal combustion engines, may be impacting the 2 I FINAL: February 22, 2012 l;\ithac3-T.6449\48281.Town-Of-lthaca\Docs\Reports\Town Of Ithaca lAQ FINALdoc QoBniENGGERE TOWN OF ITHACA | INDOOR AIR QUALITY REPORT area. Guidelines for worker exposure are an OSHA PEL value of 50 ppm, and an ACGIH 8-hour TLV value of 25 ^ > ppm. In addition, ASHRAE references the Canadian residential indoor air quality guideline of <11 ppm, the U.S. National Ambient Air Quality Primary Standard of 9 ppm, and the World Health Organization (WHO] concentration of concern at >5 ppm. Elevated concentrations have been known to cause headache and nausea. Carbon monoxide monitoring was performed using a TSl 8554 Q-Trak Monitor. Measurements were collected periodically at the five lAQ locations throughout the Town Hall for over approximately an 8-hour period on December 6, 2011. Approximate sampling locations are provided in Attachment 4 of this report The carbon monoxide measurements are also provided in Attachment 5. Temperature Temperature is an indicator for human comfort within a workspace. ASHRAE Standard 55-2007, Thermal Environmental Conditions for Human Occupancy F are acceptable and perceived as comfortable to 80% of the occupants of a space for winter conditions. Temperature monitoring was performed using a TSl 8554 Q-Trak Monitor. Measurements were collected periodically at the fi ve lAQ locations throughout the Town Hall for over approximately an 8-hour period on December 6, 2011. Approximate sampling locations are provided in Attachment 4 of this report. The temperature measurements are also provided in Attachment 5. Relative Humidity Relative humidity is the percentage of the ratio of water vapor present in the air compared to the complete saturation of water vapor at the same temperature. This parameter was chosen for the survey because relative humidity is an indicator for human comfort. ASHRAE 55-2007 provides guidelines for acceptable relative humidity. Occupied zone relative humidity shall be limited to 65% or less, when system performance is analyzed with outdoor air at the dehumidification design condition (that is, design dew point and mean coincident dry bulb temperature], and with the space interior loads (both sensible and latent] at cooling design values and space solar loads at zero. Relative humidity monitoring was performed using a TSl 8554 Q-Trak Monitor. Measurements were collected periodically at the fi ve lAQ locations throughout the Town Hall for over approximately an 8-hour period on December 6, 2011. Approximate sampling locations are provided in Attachment 4 of this report The relative humidity measurements are also provided in Attachment 5. Dust Dust is ubiquitous in the environment. Dust is made up of particles in the air that settle on surfaces. Large particles settle quickly and can be eliminated or greatly reduced by the body's natural defense mechanisms. Small particles, particles less than 10 microns in aerodynamic diameter (PMIO], are more likely to be airborne and are capable of passing through the body's defenses and entering the lungs. Many sources can produce dust including: soil, fleecy surfaces, pollen, lead-based paint, and burning of wood, oil or coal. Dust monitoring was performed using a TSl 8520 DustTrak Monitor. Measurements were collected periodically at the five lAQ locations throughout the Town Hall for over approximately an 8-hour period on December 6, 2011. Approximate sampling locations are provided in Attachment 4 of this report. The dust measurements are also provided in Attachment 5. Airborne Fungi Fungi are a ubiquitous and diverse species of microorganisms. They are present in both the outdoor and indoor environments. Factors that can contribute to fungal growth include an HVAC system, wet insulation, carpeting, ceiling tile, wall coverings, furniture, humidifiers, dehumidifiers, insects, plants, pets, and people. Since fungi are a diverse species and elicit a variety of unique responses in exposed individuals, it has not been possible to ^ \ establish regulatoiy limits. However, the ACGIH recommends that the indoor level of fungi measured in colony- ' • 3 I FINAL: February 22, 2012 ^ l:\lthaca-T.6449\48281.Town-Of-lthaca\Docs\Reports\Town Of Ithaca lAQ FINAl.doc ^ BRIEN C GERE rN TOWN OF ITHACA I INDOOR AIR QUALITY REPORT forming units per cubic meter air [CFU/m^) should be less than one-half the outdoor level, and if indoor fungi levels are greater than 1,000 CFU/m^ further evaluation of the area should be conducted. The WHO recommends indoor fungi levels of exposure not to exceed 500 CFU/m^ of common fungi. Airborne fungi samples were collected at a total of five specified locations inside the Town Hall building. Attachment 2 indicates the areas where airborne fungi samples were collected. Fungi samples were collected on standard petri dishes containing 2% potato dextrose agar (PDA) placed in a single-stage Anderson N6 impaction sampler connected to a calibrated vacuum pump by flexible tubing. Air samples were collected at a sample flow rate of 28 liters per minute (1pm) for 8 minutes, for a sample volume of approximately 229 liters (L) of air. The samples were sealed and submitted to Galson Laboratories in East Syracuse, NY to determine CFUs and microbial characterization. Chain-of-custody documentation was maintained throughout sample collection and analysis, and is provided in Attachment 6. 2.2 HVAC EVALUATION The existing Heating, Ventilating and Air Conditioning (HVAC) equipment and systems were identified and evaluated. The identification was based on the review of available design documents, which was confirmed by a walkthrough of the facility. The areas being served by the HVAC systems were identified. The evaluation was conducted by field observation and interviews with system maintenance and operations staff. The air exchange ventilation rates were calculated using the information above and air flow testing data. The air flow testing data was collected using a National Environmental Balancing Bureau (NEBB) certified testing and balancing firm subcontracted for this work. This report summarizes the field work activities, captures updates to the design documents to reflect the existing conditions, documents visual observations of the physical characteristics and conditions of the existing HVAC systems, and provides recommendations for improvements and upgrades. An opinion of construction cost estimate is also provided for the recommended improvements and upgrades. 41 FINAL: February 22, 2012 l:\lthaca-T.6449\48281.Town-Of-lthaca\Docs\Reports\Town Of Ithaca lAQ FINAL.doc QjoBmiEN&GERl! TOWN OF ITHACA | INDOOR AIR QUALITY REPORT 3. EVALUATION RESULTS f S 3.1 CURRENT AIR QUALITY CONDITIONS 3.1.1 Employee Survey O'Brien & Gere developed an online survey with 13 questions. The survey was made available to Town Hall employees from October 21, 2011 through November 7, 2011. A total of 14 employees responded to the survey. Attachment 2 contains the results of the survey. The data from this survey showed consistent concerns all days of the week, throughout the day and in all seasons of the year. The top five reported symptoms included; sneezing, temperature hot, temperature cold, eye irritation, and sinus congestion. These data did not provide enough specific information to identify a pattern to the reported symptoms that allowed a potential source of indoor air quality problems to be identified. Data from this survey was, however, useful in selecting employees for the Personal Interview portion of the Employee Survey. 3.1.2 Face-to Face Interviews Face-to-face interviews were conducted by Paul Tranchell CIH, CSP, and RBP on November 16, 2011. Data from the online survey were used to select eight (8) individuals for face to face interviews. These employees were chosen to include those with smaller, medium, and greater numbers of reported sjmiptoms. In addition one (1) employee was selected who did not complete an online survey. In addition employees were selected from the front offices, "cubical land", and the rear offices. During the survey, two additional employees were talked to at the suggestion of the Town. These employees received more focused interviews to fill in specific details regarding their work areas. 3.1.3 Pollution Source Inventory A Pollution Source Inventory was also completed during the site visit. There were few if any chemicals stored or used on site. Most of the chemicals found were cleaning chemicals and were rated as Green with no hazardous chemicals listed on the label. No significant mold contamination was identified. Minor surface contamination was found on the outside wall in the old switch room. HVAC equipment was clean and with no indication of dust build up in the system or ducts. Based on the Inventory, no additions to the original list of chemical monitoring were indicated and the sampling for formaldehyde was not considered warranted. 3.1.4 Air Sampling The air sampling strategy that follows was established by Paul W. Tranchell CIH, CSP, RBP and is based on the on the results of the online suivey, personal interviews, and the Pollution Source Inventory. Carbon Dioxide The average carbon dioxide levels measured in the sampled areas are presented in Attachment 4. The average carbon dioxide concentrations in the sampled areas did not exceed the OSHA PEL of 5,000 ppm or the ASHRAE performance standard. The highest average carbon dioxide concentration was 634 ppm measured at lAQ 01 (Judy Drake's Office). The lAQ measurement log is provided in Attachment 2. Carbon Monoxide The average carbon monoxide levels measured in the sampled areas are presented in Attachment 4. The carbon monoxide concentrations in the sample areas did not exceed the OSHA PEL of 50 ppm, the ACGIH TWA of 25 ppm, or the US National Ambient Air Quality Standard of 9 ppm. The highest average CO concentrations were 0.4 5 I FINAL; February 22, 2012 l:\lthaca-T.6449\48281.Town-OMthaca\Docs\Reports\Town Of Ithaca lAQ FINAL.doc Qqbrienggere TOWN OF ITHACA I INDOOR AIR QUALITY REPORT ppm measured at both lAQ 01 Qudy Drake's Office) and lAQ 02 (Basement Lobby). The lAQ measurement log Is provided in Attachment 2. Temperature The average temperature levels measured during the lAQ monitoring event were within the ASHRAE recommended range for winter conditions. Room air temperature is a comfort issue not regulated by OSHA. The temperature ranges identified by ASHRAE 55-2007 for summer and winter conditions that are anticipated to be acceptable to at least 80% of the occupants are: Summer conditions 74°-83°F Winter conditions 67® - 78®F Average temperature readings are provided in Attachment 4. Temperature readings outside the ASHRAE recommended values may not be considered at a comfort level for some employees. If workers indicate a comfort issue with thermal conditions, appropriate adjustments should be investigated to meet the workers concerns. Relative Humidity Relative humidity levels measured were below the 65% levels recommended by ASHRAE. The ASHRAE inside design conditions specified for relative humidity associated with an office building Is 65% or less. Fluctuations of relative humidity levels maybe associated with dry skin and mucus membrane irritation, use of humidifiers and the presence of water or condensation, which are typically considered as a comfort issue. The average relative humidity measurements are summarized in Attachment 4. The lAQ measurement log is provided in Attachment 2. Dust Dust concentrations measured during the lAQ monitoring event were below the O.OSO mg/m^ levels recommended by The US Green Building Council. The highest average dust concentration was 0.009 mg/m^ measured at lAQ 05 (Court Office). The average dust measurements are summarized in Attachment 4 and the lAQ measurement log is provided in Attachment 2. Airborne Fungi The airborne fungi levels measured in the sampled areas ranged between < 14 CFU/m^ to 71 CFU/m^. The airborne fungi levels measured in the sampled areas were well below the ACGIH target level of 1,000 CFU/m^ and WHO-recommended indoor level of 500 CFU/m^. The Galson Laboratory report, chain of custody documentation, and data recording sheet are provided in Attachment 3. The average airborne fungi data is also summarized in Attachment 4. 3.2 HVAC EVALUATION 3.2.1 Field Investigation Record Drawings Review and Field Confirmation The Town provided copies of HVAC drawings from their records file. The drawings are from the latest major renovation dated 3 November 1999. In general, the drawings show a central Roof Top air handler Unit (RTU-1) that serves to ventilate and cool the building. RTU-1 is connected to the rooms by a system of distribution supply air ductwork. Comfort in the rooms is provided by Variable Air Volume (VAV) control boxes at the zone level. The zones consist of one or more rooms. In one of the rooms, an air temperature sensor provides input to the zone controller to maintain room comfort. The Building Control System (BCS) regulates the flow of cooling air, or if necessary opens the zone hot water heat valve to maintain room comfort. Zone hot water heat is provided on VAV control boxes to heat the supply air to the zone as necessary. The Town Hall Records Vault has a dedicated system provided by a Liebert air conditioner to stabilize the environment in the room suitable for long term storage of paper record files. Additional heat is provided along the building perimeter by a system of hot 6 I FINAL: Februaty 22, 2012 Bi OBRIEN G GEREl:\lthaca-T.6449\48281.Town-Of-Ithaca\Docs\Reports\Town Of Ithaca lAQ FINAL.doc TOWN OF ITHACA 1 INDOOR AIR QUALITY REPORT water baseboard heaters and cabinet heaters that are not directly controlled by the BCS but rather by local ^ mechanical control valves at the heaters. Exhaust fans provide spot ventilation in the Toilet Rooms and the Elevator Machine Room. Hot water is provided by two boilers located in the basement. Generally, the entire occupied portions of the Town Hall are served by these HVAC systems with the exception of the upper and lower levels of the front offices in the older portion of the building which are not currently occupied. The space adjacent to the Town Hall is the Post Office Store which is not served by these HVAC systems described above. At the end of the report find Attachment 8 which is a detailed characterization of the HVAC system. The characterization describes the HVAC system including its components at the Town Hall and is based on the walk through conducted by O'Brien & Gere and a review of the drawings provided by the Town. Measuring Air Flows The air exchange ventilation rates were calculated using the drawings provided, information collected during the walk through and airflow testing data. The airflow testing data was performed by New York Technologies, a National Environmental Balancing Bureau (NEBB) certified testing and balancing firm subcontracted for this work. At the end of this report find Attachment 8, the summary data of the air flow testing work. The data was used as input for the calculated ventilation rate summary below. From the attached report, the fan test report sheet shows that the RTU supply air fan was delivering 75% of the design maximum air flow. This is on the high side for winter but Indicates that the energy saving fan speed control is functioning. From the attached report, the air outlet test report sheet for supply air indicates the different VAV controllers in the right most column. The room served by the individual VAVs are shown in the left column. The rooms served by a common VAV are in the same zone. Air flow in VAV zones 1, 3,4, 5, 6 & 7 were measured near the maximum design flow rate. Air flow in VAV zones 2,8 & 9 were measured near the minimum design flow rate. VAV zones 2 8i 9 both serve one-half of the large work room with the high ceiling and, as expected, the cooling airflows were low to match the cooling loads. VAV zone 8 is in the basement and the low cooling loads were expected. In VAV zone 3 the high air flow rates at the zone level were expected. In zones 1, 4, 5, 6 & 7 the cooling load was expected to be in line with zones 2 & 9. Analyzing the design drawing equipment schedules shows that the hot water reheat coils located at the VAV control boxes are intended to deliver heated air at the minimum VAV air flow rates scheduled, so it is likely that the zones were not in heating mode. It is possible that the hot water heaters on the perimeter of the building were set to heat above the cooling set points and the cooling system was working to maintain its set point at the same time the heaters were operating. From the attached report, the air outlet test report sheet for return and exhaust air indicates measured data for the rooms indicated on the left column. Comparing the supply air flow to the return air flows indicates, in general, that the small rooms tend to bypass the dedicated return air grilles in the rooms. The tests were performed with the office interior doors open. When the doors are closed, the return air grilles in the rooms will be forced to function to the full capacity. When the doors are open, the return air travels to the adjacent larger rooms return air grilles. Specifically, this was measured in the area of large work room with the high ceilings. There are two rows of small offices in this area. The first row is located directly to the south and includes the Conference Room by the Court. This row of offices is served by VAV-3, is totally within the interior of the building and should be in cooling mode at all times with the possible exception of a brief morning warm up period. The supply air was measured near the maximum scheduled indicating appropriate cooling load. The second row of offices is located to the east and down the hallway and includes the large Conference Room to the Town Supervisors Office. This row of offices is served by VAV-1, is exposed to the exterior wall and should not be in a high cooling mode. The supply air was measured exceeding the maximum scheduled air flow for cooling. The air flow should not be this high. Both rows of offices return air grilles in the offices were measured with significantly less air than the corresponding supply indicating that the return air was traveling to other parts of the building through the open interior doors. The large work area was measured with expected supply air flow ^0^ to match the cooling load but the return air was significantly higher indicating that return from the adjacent office was probably routing through this space. Although return air should conditioned be to room temperature, ^ ^ 7 I FINAL: February 22,2012 l:\lthaca-T.6449\48281.Town-Of-lthaca\Docs\Reports\Town Of Ithaca lAQ FINALdoc QaBniENGGERE TOWN OF ITHACA | {NDOOR AiR QUALITY REPORT f ^ excessive air movement can cause uncomfortable drafts that are more noticeable in the winter. With excess air flows in the VAV-1 zone, this condition should be corrected. 3.3 CALCULATED VENTILATION RATES (CODE SUMMARY) Outside air enters the building through the RTU and is continuously distributed during the occupied mode through the ductwork to the rooms. The balance of the outside air coming into the building is exhausted through the toilet room exhaust fans continuously during the occupied mode. The day of the air flow testing, the RTU outside air damper was at approximately 10% open. The exhaust fans operating at the time of testing was restricted to only EF-2 serving the two Toilet Rooms 128 and 129 in the lower level of the cubical land and totaled 138 cfm for the two rooms. The Mechanical Code of New York State - 2010 (Code) requires 75 cfm per water closet for toilet rooms so EF-2 would be considered to be in compliance within normal tolerances for air systems and air flow measuring methods. As EF-2 was the only exhaust fan operating, this 138 cfm is the total measured outside air flow for the building on that day. The exhaust rate is designed to include EF-1 operating at 675 cfm and the existing fan in the basement operating at 200 cfm. Combined with the design air flow rate for EF-2 of 150 cfm the total should be 1,025 cfm. The Code has a basic requirement of 20 cfm per person. The design exhaust rate is sufficient for 51 people which is reasonable for an average occupancy for this building. The Records Vault does not have an outside air component to the dedicated air conditioner system serving the area. The Records Vault is considered an occupied area and should be provided with mechanical ventilation in accordance with the Code. t \ 8 I FINAL: February 22, 2012 l:\lthaca-T.6449\48281.Town-Of-lthaca\Docs\Reports\Town Of Ithaca lAQ FINALdoc 0QBRIENSGERE TOWN OF ITHACA | INDOOR AIR QUALITY REPORT 4. RECOMMENDATIONS 1. Water intrusion was noted along the west wall of the boiler room. While it was not clear whether the dark area was associated with mold or dirt, such intrusion can contribute to mold, indoor air quality issues as well as water damage. The source of the intrusion needs to be identified and the intrusion stopped. 2. A small amount of surface mold was noted on the Buffalo Street wall of the DeMark Room. Clean this surface mold in accordance with OSHA guidance. 3. Continue the existing maintenance program of the system including the regular filter change outs. The filters have filtration efficiency within good practice for a public building and exceed the minimum Code requirements. 4. Continue to maintain the seal in the return air plenum located above the cubical area and below the RTU. The seal includes wall seams with the roof and floor; seams where ductwork penetrates the wall, floor and roof; pipe penetrations; and the access door gaskets. Continue the mandatoi7 practice of keeping the access door closed. 5. Continue to maintain the ductwork insulation including the aluminum foil vapor barrier on the exterior of insulation. This is especially a concern in the two mechanical mezzanines where the soft duct insulation is exposed to abrasion. 6. Continue the existing maintenance program of periodically changing out the humidifier cartridge in the Records Vault air conditioner AC-1. 7. Adjust the set point for the cabinet heater in the Records Vault to a position below the heating set point of the air conditioner AC-1. The suggested set point for the cabinet heater is approximately 5®F below the set point of AC-1. This allows the cabinet heater to function as a backup heater and precludes the cabinet heater from operating while the AC-1 system is in cooling mode. Confirm the control valve for the cabinet heater closes completely and does not allow hot water to seep to the heat coil. 8. Modify the ductwork in the Records Vault to Include some outside air ventilation. Cut into the existing supply air duct routed through the Records Vault Install a six-inch round duct to supply a new Constant Air Volume (CAVJ control box and then direct the ventilation air to the return air plenum of the AC-1 unit. The CAV box is similar to a VAV control boxes except that it supplies a constant air flow volume even if the pressure in the supply duct changes. In this case, the supply air duct is downstream of VAV-8 which provides cooling and ventilation to the basement based on the wall thermostat in the Employee Lounge. So, as the pressure in the supply air duct varies in accordance with the normal operation of the VAV-8 zone, the CAV control box will automatically adjust to maintain a constant air flow to the Records Vault. Adjust the CAV set point to 75 cfm. Install a 6"x6" return register in the existing return air duct to balance the ventilation supply air. 9. Modify the BCS and fan controls so exhaust fan EF-1 operates continuously during the occupied mode. EF-1 serves the three toilet rooms in front offices. Confirm the air flows in the toilet rooms are in accordance with the original 1999 design: 300 cfm in each of the two public access toilet rooms and 75 cfm in the smaller toilet room adjacent to the nearby offices. 10. Modify the exhaust fan system serving the toilet rooms in the basement by replacing the fan with one sized for the toilet room air flows in accordance with the 1999 design. Provide 100 cfm for each of the two toilet rooms. The construction cost estimate below assumes the ductwork can be significantly reused requiring only minor modifications at the fan connections, BCS controls can be significantly reused requiring only minor modifications and that a new 120 Volt electrical power circuit will be installed. 9 i FINAL; February 22, 2012 l:\lthaca-T.6449\48281.Town-Of-lthac3\Oocs\Reports\Town Of Ithaca lAQ FINAL.doc I^QBRIENCGERE TOWN OF ITHACA 1 INDOOR AIR QUALITY REPORT 11. Modify the maintenance program to include annual recommissioning. This allows for a periodic independent proving of the system functions and set points and limits energy waste by maximizing the efficient use to the energy used. Specifically, the air flow testing indicated that several VAV zones were delivering a high air flow rate when the zone should not be in a high cooling load. The Town Board/Court Room was unoccupied with the main lights off. The Lobby, Front Offices and the VAV-1 zone from the Conference Room to the Town Supervisor's offices have exterior walls exposed to the 31°F outside air temperature. These zones should be delivering a lower air flow rate and most likely be in heating mode when the air flow needs to be at the minimum air flow scheduled in the 1999 design. Change or confirm these zone air flow settings for the heating mode in the BCS. Change or confirm these zones hot water cabinet heaters set points are at or below the VAV heating set point to avoid operating heating and cooling at the same time. Although not directly related to lAQ concepts, but noticed during the walk through, the following items should also be considered. 12. Modify the hot water cabinet heaters and baseboard heaters controls from local self contained mechanical controls to electronic controls as part of the BCS. This will allow the heaters to be used in the occupied mode as supplemental heat and in the unoccupied mode with an energy saving night set-back temperature setting. This will also allow for a central control system that will help avoid the possibility of heating and cooling at the same time in a zone. Considering the air conditioner control zones that already group several rooms into common zones and adding for toilet rooms with hot water heat a total of nine electronic control valves will be needed. The energy savings has not been estimated but would come from the ability to control the night set back heating temperature, typically 5®F from 72®F to 67°F. The energy savings was not estimated because the hot water heaters are likely intended to have set points at the lower night set-back level by design. This change would maximize comfort in the heating mode because the original design included forced air heating at the minimum VAV air flow rate. This heating mode at the minimum VAV air flow rate is common but does have some practical limitations. The system forced air design uses overhead supply air diffusers which are designed for cooling. In the heating mode, the hot air has a buoyant effect that makes it difficult to fully deliver to the lower occupied levels of the room. This can be exacerbated with a minimized air flow rate setting and high ceilings which can lead to the heated air short circuiting directly to the return air grilles. The exterior walls include cooler windows and can create down drafts of cool air in the room. Together the heating mode can have limited effect on the inside air temperature at the occupied levels in the room and would have a limited effect on countering the cool down drafts along the exterior walls. By using the perimeter heaters in harmony with the VAV forced air heat at the designed minimum air flow rate, heat is provided at more strategic locations in the room. The cool draft at the exterior wall would be addressed with a heated updraft that pulls the cool air from the floor, through the heater and up to the higher levels of the room where it can mix with the ventilation air. The result would be a more uniform temperature throughout the room and increased ventilation air mixing in the heating mode. 13. Modify the boiler supply water temperature set point. There does not appear to be a boiler supply water temperature reset. Reset would allow the supply water temperature to lower during all but the peak heating conditions based on outside air temperature, Energy savings would be realized by avoiding having to heat entire hot water system to the maximum temperature all the time. 14. Install a belt guard on EF-1 located in the attic over the front offices. 4.1 ADDITIONAL FINDINGS 4.1.1 Record Drawings Review and Confirmation The design documents provided by the Town were from the latest major renovation dated 3 November 1999. These drawings were provided to O'Brien & Gere as copies from the files and the copies were able to be reproduced with above average print quality. Further, the HVAC designs on the drawings are, in large part, an 10 I FINAL: February 22,2012 Qobriensgere l;\lthaca-T.6449\48281.Town-Of-lthaca\Docs\Reports\Town Of Ithaca lAQ FINALdoc TOWN OF ITHACA | INDOOR AIR QUALITY REPORT accurate representation of the existing conditions at the Town Hall. However, the few items below were noted as minor changes in the existing construction compared to the design drawings: n On Drawing No. MlOl - In the Records Vault, the dedicated air conditioner AC-1 is shown located along the west wall rather than its current location in the middle of room east of the location shown. n On Drawing No. M103 - EF-1 and its associated ductwork are shown in an "L" configuration rather than the current mirror image of the "L" configuration. The duct riser is located above the Toilet Rooms. The exhaust duct is shown routed north to an elbow and then to an easterly duct where the fan is shown. The existing construction has the same duct riser but with an easterly duct to an elbow and then a northerly duct where the fan is located. The length of duct and number of fittings is the same but the current routing and fan location is conveniently along the access cat walks. n On Drawing No. M104 - In the Records Vault, a hot water cabinet heater is located on the south wall at the west corner. This cabinet heater is not shown on the design drawings. 4.1.2 Opinion of Probable Construction Cost Recommendation #8, add ventilation air to the Records Vault: CAV control box, ductwork, duct insulation, air grille and balancing $3,200; reprogramming the BCS with one man for one day is estimated to be $1,000 for time and $200 for travel; 40% contingency; total estimate = $6,160. Recommendation #9, EF-1 to operate during occupied mode includes time for reprogramming the BCS with one man for one day is estimated to be $1,000 for time and $200 for travel; 40% contingency; total estimate = $1,680. This estimate assumes no parts are required. Recommendation #10, new exhaust fan to replace the old fan: assume new size fan motor is 120 Volt and replaces three-phase fan motor; demolition of fan, fan power and controls $800; extend new 120 Volt power and controls, assume BCS is already there and can be reused, $1,500; fan $1,100; ductwork modifications $500; 40% contingency; total estimate = $5,460. Recommendation #11, annual recommissioning: includes testing, adjusting and balancing the existing VAV forced air system $5,000 ; and adjusting the programming set points in the BCS using a separate controls contractor $5,000; 40% contingency; total estimate =$14,000. Recommendation #12, add perimeter heaters to the BCS: includes all of the work in #9 above plus nine zone controls $13,500; $2,200 for the retrofitted hydronic system work; 40% contingency; total estimate =$22,000. This does not include an allowance for repairs found needed or engineering and assumes the BSC has sufficient capacity to add these control elements. 111 FINAL: February 22. 2012 l:\lthaca-T.6449\48281.Town-Of-ltliaca\Docs\Reports\Town Of Ithaca lAQ FlNAL.doc Qobrien&gere ATTACHMENT 1 Online Survey f ? t ^ p \ 360* Engineering and Project Delivery Solutions G OBniENBGERE Town of Ithaca Town Hall Occupant Health and Comfort Questionnaire Page 1 of 5 / \ » Member login » Send my own surveys » Quick tour Town of Ithaca Town Hall Occupant Health and Comfort Questionnaire Survey Results 1 ^ Please enter the following: Vitw Individuot Retponset View 14 Responses 2, I Area or room where you spend the most time in the building: View 14 Responses I Do any of your work activities produce dust or odor?

Galson Laboratories provides an estimation of the density of these particles, referred to as a Crowding Factor. The Crowding'Factor ranges from 0 to 5 and is explained below. High levels of paniculate matter on the impaction sample may bias the analysis by obscuring or covering spores. In addition, particle capture efficiency may decrease with high levels of paniculate matter. Crowdmg Factor I Explanation 0 No particles detected. This is typical of blank samples. Because most air samples typically contain some particles, absence of paniculate matter could indicate improper sampling ' if the sample was not meant to be a blank. 1 Particles are far apart and in low numbers. Paniculate matter covers approximately <5% of the impaction area. Spore counts not affected or minimally affected by the particle load. 2 Particles are close together and/or overlapping, and some spores may be obscured. Particulate matter covers approximately 5% to 25% of the impaction area. Spore counts may be biased low. 3 Particles are moderately crowded. It is likely that some spores are obscured. Particulate matter covers approximately 25% to —— I 75% of the impaction area. Spore counts are likely biased low. 4 Particles are crowded, frequently obscuring spores. Particulate matter covers approximately 75% to 90% of the impaction area. Spore counts are likely biased low. The degree of bias increases with the percent of the trace that is occluded. 5 Particles are overcrowded making analysis impossible; no spore counts provided. If certain spores are readily detectable, I they are reported as "Detected". Counts for any genus that exceed 300 spores are estimated to two significant figures. Direct Microscopic Examination (Screens) • Due to the inherent nature of screen samples, a spore count is not performed.

The unit is located on the roof above the mechanical mezzanine. The filters are two stage. First stage is a two-inch thick prefilter with MERV 8 rating. Second stage is a twelve- inch deep bag type final filter with a MERV 10-14 rating. The prefilters are reportedly changed twice a year and the final filters are reportedly changed once a year. The filters looked in good condition and at approximately half their sei^ice life before a change out is due. The unit is capable of providing Variable Air Volume (VAV] supply air with the intent to save on fan power by controlling fan speed in all but hottest weather in response to the cooling demands of the zone VAV control boxes. Economizer mode, also known as free-cool, is provided when the zones demand cooling and the outside air temperature is low enough with the intent to save on condensing unit energy during cool weather. RTU-1 is controlled by the Building Control System (BCS) to operate continuously during the occupied periods and operate only on demand during the unoccupied periods to save fan energy. RTU-1 appears in good mechanical condition and functioning correctly and is at approximately half of its twenty-year design life. The distribution ductwork connects the RTU to the building zones and rooms. The supply and return air ductwork made of galvanized steel. The majority of the ductwork was installed new as part of the 1999 renovation with a few exceptions in the older building Court and Lobby areas. Each occupied room in the cubical land in the newer portion of the building is also served with supply and return air grilles. The at-grade level of the front offices is served with supply and return air grilles. The area above and below the front offices are not served by the RTU or its ductwork and are not currently occupied. The return air ductwork has a plenum between the distribution branches and the connection at the RTU so that the return air ductwork is not directly connected to the RTU. The plenum is the mechanical mezzanine space directly below the RTU. This plenum is a walk-through mechanical room constructed of building elements including the plywood floor, interior partitions and roof deck. The plenum has been well sealed and includes a regular interior access door with weather stripping. The door has a bold sign as a reminder to keep the door closed. It is important to keep the door closed or the return air ductwork effectiveness will be significantly reduced. The plenum seal construction is effective because as the door closes, the air flow will forcibly close the door. The sealing of this room is important for proper HVAC system function but the plenum appears to be working well at this time. The ductwork is in good condition and is at the beginning is its service life. The ductwork insulation is in good condition and is between the beginning and half of its service life. The VAV control boxes are provided for each zone, are located in the supply air ductwork and function to adjust the amount of cooling air to match the comfort in the rooms. The adjustment is provided by an electronic control motor that positions a damper to maximum open, minimum closed or anywhere between. The maximum and minimum positions are chosen by the designer to match the maximum cooling and minimum ventilation requirements of the rooms. The VAV boxes also have a hot water coil to heat the ventilation air and provide comfort heat to the rooms. The VAV boxes appear in good condition and at approximately half of their design life. The BCS is a Carrier product. The system consists of a central controller located in the Boiler Room, an operator interface computer located in the basement Storage Room and point control elements. The point control elements are located throughout the building and consist of room temperature sensors, VAV control boxes, and motor starters for exhaust fans and the RTU. The system controls the room set points, the occupied and unoccupied modes including night set back, and the RTU functions. The BCS system does not control the hot water heaters installed around the perimeter of the building. The BCS is generally intended to control the comfort of the building and the energy saving features of the HVAC equipment to which it is connected. The BCS has recently been updated with new software and is reportedly in good condition at approximately half of design life. 360' Engineering and Project Delivery Solutions iAlth3c3-T.6449\48281,TQwn-Qf-lthac3\Docs\Reports\Attachment 8 HVAC Charaterization.Doc Qobrienbgere ATTACHMENT A - CHARACTERIZATION OF THE HVAC SYSTEM The Records Vault has a dedicated split system air conditioner located on the floor in the room. The air conditioner has a condensing unit located on the roof. The air conditioner has capability for temperature and humidity control to stabilize the environment in the room suitable for long term storage of paper record files. The humidifier cartridge element has recently been replaced. The system appears in good condition and is at approximately half of its design life. The Records Vault is not served by the RTU system. There is a cabinet heater located in the corner of the Records Vault that is connected to the hot water heating system. This cabinet heater is not controlled by the BCS or the dedicated air conditioner and operates independently. In addition to the heat provided by the VAV boxes, heat is also provided to the building perimeter by a system of hot water baseboard heaters and cabinet heaters that are not directly controlled by the BCS but rather by local mechanical self contained control valves at the heaters. These control valves operate independently of the BCS and the cooling system. It is possible for the heaters to operate while the room is in cooling mode. Exhaust fans provide spot ventilation in the Toilet Rooms and the Elevator Machine Room. The Toilet Rooms exhaust fans are intended to be controlled by the BCS to operate during the occupied mode. At the time of the walk-through exhaust fan EF-1 serving the Toilet Rooms in the front offices had been programmed to not operate during the occupied mode. The operating personnel from the Town were able to energize EF-1 by manually selecting "hand" on the hand-off-auto switch at the fan local control panel which is located in the attic. The Elevator Machine Room exhaust fan is controlled by a wall mounted thermostat and is intended to energize the fan when the room air temperature rises to the set point. These fans appear in good condition and are at approximately half of their design life. The exhaust fan sei-ving the basement Toilet Rooms adjacent to the Employee Lounge is reportedly not operating and was not accessed during the walk-through. This exhaust fan is reported as older than the 1999 renovation and is likely at the end of its design life. 360' Engineering and Project Delivery Solutions l:\lthaca-T.6449\48281.Town-Of-lthaca\Docs\Reports\Attachment 8 HVAC Charaterization.Doc QoBniENGGERE ATTACHMENTS HVAC Report 360' Engineering and Project Delivery Solutions G OBRIENGGERE CERTIFIED TEST, ADJUST, AND BALANCE REPORT HI Date: 12/19/11 PROJECT:TOWN OF ITHACA - TOWN HALL ADDRESS:ITHACA, NEW YORK ENGINEER: ARCHITECT: HVAC CONTRACTOR:O^BRIEN & GERE ENGINEERING, INC 333 W.

Dates Drive. The committee asked staff to prepare a summary of the comments expressed at that meeting for Town Board members information in advance of the February 27*'' Study Session meeting. These comments are summarized below. For reference, all Town Board members should have received (via the Planning Committee meeting materials) paper and/or digital copies of documents related to the County proposal, including the 2/10/12 draft Request for Proposal, the 2/8/12 draft Pedestrian Neighborhood Zone regulations, and the EcoVillage at Ithaca: Principles, Best Practices & Lessons Learned document. Graphics associated with the Pedestrian Neighborhood Zone were provided at the Planning Committee meeting and are attached for your information. Committee comments: ^4^ • The location on Harris B. Dates Drive for the 70-unit housing development is a concern. This location is currently being contemplated (through the Comprehensive Plan process) as suitable for institutional type uses, such as an assisted living facility or nursing home, rather than a residential neighborhood. As described in the RFP, the viability of the housing project seems to be predicated on the success of the County's vision for the "hospital node" on West Hill which might be in conflict with the Town's desire to concentrate mixed use and residential development further to the south and on the west- side of Route 96. • The proposal to exclude cars from the interior of the neighborhood community and restrict them to parking area(s) along the perimeter, as described in the draft Pedestrian Neighborhood Zoning (PNZ) Regulations, is of concern. According to the PNZ, parked cars would be located in designated areas "not more than 1250 feet from the main entry of any building". The PNZ language seems too restrictive and should incorporate more flexibility for motor vehicle accessibility so that residents could still be accommodated as their mobility needs changed (through aging, accidents, etc). In addition, the proposed development, as it has been described, seeks to attract a broad spectrum of residents and be replicable in other locations, but it is unlikely to attract a wide variety of individuals unless accessibility to motor vehicles is made reasonably convenient (i.e. shorter distances). • The car-restrained development, as proposed, would likely appeal to individuals who for reasons of choice or necessity do not own a car. The West Hill area, however, is largely a car-dependent area with no services outside of the hospital and some specialized medical offices. This type of development would be more conducive in an urban or I mixed use suburban area (i.e. East Hill). The Request for Proposals (B^) includes points (used in a scoring system) if the developer provides passive recreation trails for the new community's use within the t \ undeveloped wooded portion of the County property. The RFP should also include ' ' points for a connection to the Black Diamond Trail. The RFP indicates that the development would be integrated and have pedestrian connections with the Cayuga Medical Center and other future developments. Pedestrian access for transit service will be very important in this location and the RFP should acknowledge this and include a requirement for the siting of a bus shelter. The proposed development would potentially be an ideal "Ithaca Carshare" location and exploring the possibility of having a dedicated spot built into the community should be included in the RFP. The RFP does not address how the provision of 20% affordability would be enforced and administered nor does it indicate intent to insure affordability over the long-term (subsequent buyers). This will need to be clarified and detailed in any future Planned Development Zone. The property seems to have a potentially inflated assessed value which could impact the interest of developers in the project and the County's expectations for selling the land. According to Tompkins County Assessment, the Harris B. Dates Drive property is listed as having an appraised value of $500,000 for the 25.5 acres of undeveloped land. The appraisal classifies the property as vacant commercial. The term "non-affordable" is used on page 2 (5th bulleted item) which states "Develop at least half of the "non-affordable" units so they would be affordable to middle income households..." This should be replaced with the term "remaining" rather than "non- affordable". 1 ^ * MIXED APARTMENTBUILDINGS50 UNITSUNIT COUNTS BASED ON 5 STORYHEIGHT FOR APARTMENT BUILDINGSAND SINGLE FAMILY OCCUPANCYFOR ROWHOUSESSINGLE BUILDING45 UNITSLARGEST LOT: 1S0*FRONTAGE, 20,000sf30' MULTI-MODE PATHWAY20* pedestrian pathway40' MULTI-MODE PATHWAYSMALLEST LOTS:20' FRONTAGE, 1200sfROWHOUSES14 UNITSBUILDINGS WITHOUTFRONTAGE ON MULTI-MODE PATHWAYLIMITED TO 3 STORIESAPARTMENT BUILDING+ ROWHOUSES28 UNITS0' 20' 40' 60' 80' 100'Tl ((Urban Mixed-Use (UM) District density potentialJ) )t -J0' 100' 200' 300'ZoneMDRHDRNew UrbanPZLand Area2480IS.Iac6.44ac6.38CDU/acre2.94.610.811 1Relative size100%63%27%26%Roadway2.950lf@24'vride2.250lf @ 24' wide1.060lf@28' wide1,C25lf@12' wideRoad surface area70,800sf54.000sf29,680sf12 300sfDriveways/parking48.500sf48.S00$f23,900sf41 800sfPaths/sidewalks2.400sf010.600sf2.700sfTotal Paving121.700sf102.5008f64.160sfS6.800sr% paving11.5%15.5%22.8%20.6%Common Space00019.000sf% common0007%Plans compare development of 70 dv/ellingunits, 1/3rd of which are 2-famiiy houses,resulting in a 47 lot subdivision.irrr'rmnPTown of Ithaca - HDR zonefiFall Creek" New UrbanPNZ - VR District PNZ-VR District"Fall Creek" New Urban.5",, lo' rgAVfiU 'J,5'a6o' 1 RtOtW*Town of Ithaca - HDR zone333 ))1^4^** Ftoo*!. s«Ta>^fcfc3 HAy,UM District 1^>' R.O>W» sfte' jMlhitMUM "T 'j""">1 5Te(LY MIKJ.1ll^J 1/^ VR District i 1 ,S ■WTVM S f T WO'>l ,o£ (ft J I \
