The project was advertised on NYS Contract Reporter on October 25, 2013 and the City received 13 proposals on November 15, 2013. After reviewing the proposals, a Consultant Selection Committee ( Addisu Gebre, Tom West and Tim Logue) has selected Delta following all applicable Federal consultant procurement requirements. Upon completion of the selection process, the contract scope and fee were negotiated with Delta. I have recently worked with Delta on E Clinton St. Bridge Replacement and Prospect St. Reconstruction Projects. I am comfortable with Delta's expertise to perform in a cost effective manner and also to deliver excellent design solutions; therefore, I am ready to recommend that you award the contract to Delta in an amount not to exceed for $95,495. ------------------------------------------------------------------------------------------------------------------- This project involves the replacement of Brindley Street Bridge over the Cayuga Inlet, including necessary approach work. Currently anticipated work. items include complete replacement with new two lane structure with accommodations for bicyclists and pedestrians. As part of this project, improvements in traffic operations and safety at the multi -leg intersection compromised of West State Street/W. Martin Luther King Jr. Street, W. Seneca street and Brindlye Street are proposed. If you have any question, please call Addisu Gebre, Bridge Systems Engineer at 607 - 220 -7581 or agebreacityofithaca.org.

The banner is 9 feet width and 12 feet in height. (We also have one 6' x 8' of the same image if 12' is too tall.) See image attached. The banner has grammits and would be fastened with heavy zip ties or wire to the fence. It would be great to have the banner up into the summer if possible.

Wood Street Park is located in the P -1 (public and institutional) zoning district. There is no building or business that I am aware of in Wood St. Park that we could count as frontage. You would be allowed 1.5 SF of signage for every lineal feet of building or business not to exceed two (2) signs at 50 sf max each if such business existed. The proposed banner is 9 X 12 feet ( ?) 108 SF or 9 inches X 12' ( ?) 9 SF. If this is to be a temporary sign the following pertains: Temporary signs advertising an event for less than 10 days are not required to get a sign permit (272 -8(A). Temporary signs exceeding 60 days requires a permit (272 -8(C). Please note that the banner should be securely fastened (and /or framed) so as not to blow in the wind. As this is City owned property I would recommend that the proposed sign be brought before the Board of Public Works. If a sign permit is required I would need consent from the property owner in order to allow the sign to be erected on the property. I hope this helps.

This program, under the federal transportation law, essentially replaces the former Transportation Enhancement Program and folds within it a few other, smaller programs, such as Safe Routes to School and Scenic Byways. Staff attended a TAP training recently and we are interested in applying to the program. We seek direction from the Board for project selection and a recommendation to Council to approve the application and provide the local share (at least 200 of the total project cost). The City of Ithaca is eligible to compete for approximately $1.75 million within our NYSDOT region. Based on past experience, they might award 3 such grants in the region, meaning a "target" value for funds would be around $600,000 in federal aid. With the 20% local match, a total project cost could be around $750,000. Anything larger than that would likely require a match of more than 20 %. Staff would like to put forward four possible projects for the Board to choose among to recommend to Common Council for approval to submit and for the commitment of the local share. Below are the projects with some notes about how each one might fit the TAP. The Cascadilla Creekway The City recently closed the Sears Street pedestrian bridge over Cascadilla Creek due to structural concerns. We believe there is a strong community desire to rebuild this bridge. The railings along the creek are woefully substandard and need replacement. The segment of Cascadilla Avenue from Tioga Street to Page 1 of 3 'An Equal Opportunity Employer with a commitment to workforce diversification." 0 Cayuga Street is part of the Ithaca Bicycle Boulevard plan and an opportunity exists to redesign the shared space along the creek to be more pedestrian and bicycle friendly and calm traffic. Interpretive signs could be included, too. Lastly, the BPW was interested in some enhancements at the intersection of Cayuga Street and Cascadilla Street; this work could be included in the project, as well. This project is likely in the ballpark of $750,000, meaning it would require a $150,000 commitment from the City for the local share. We do not currently have bicycle or pedestrian counts for this area, but we believe them to be substantial. We think this project would be eligible and competitive. The City Court Pedestrian Bridge The City recently closed the pedestrian bridge over Six Mile Creek that is between the back corner of the library and the City Court/ Ithaca Police Department. Unless additional funding is provided, we understand that it is the City's intention to maintain this bridge only to carry utilities, but to keep it closed to the public. A current construction cost estimate states that the utility related work will cost about $75,000; design and inspection will increase these costs. The City has $50,000 already authorized for maintenance related work that could be used as most of a local match. We do know that the Planning Department and Police Department have requested that the City work to reopen the pedestrian bridge; presumably the City Court would be interested in this as well. A total project cost for this project would be in the neighborhood of $300,000. We think this project would be eligible and competitive. The Hector Street Sidewalk Over the years, a large sidewalk construction project such as Hector Street, from where the sidewalk ends to the City line, has been a topic of conversation and a possible project for similar funding. To date, we have decided that such a project would be eligible, but due to the previous mechanism for paying for sidewalk, it was usually concluded that there would not be enough community support for such a project, if the adjacent property owners had to pay for a portion of the project. Additionally, it has not been clear to staff that such a sidewalk project would be particularly competitive, with the understanding that there may not be enough density of users on West Hill to make a strong case for the sidewalk. It certainly has its benefits, but we were not sure how they would rank compared to other projects in Tompkins County or central New York. That said, it certainly is an eligible project and we don't want to forget about the possibility of using a program such as TAP as a way to fund a large capital project to construct new sidewalk. A total project cost estimate for extending the sidewalk from Vinegar Hill Road to the City line would be about $1.5 million. It would be possible to Page 2 of 3 use Sidewalk Improvement District funds for the local match or a portion thereof. A project of this scale would require an "overmatch" of more than 20% of the total project costs in order to remain competitive within our region. As noted above, we might be able to get upwards of $600,000 to $700,000 in federal aid; but the rest would need to be a local match. The Black Diamond Trail bridge over the Flood Control Channel This past summer we constructed the Floral Avenue Trail along the Flood Control Channel, which is also a segment of the Black Diamond Trail (BDT). The southern terminus of our construction is where, according the BDT Master Plan, the trail will cross the Flood Control Channel on a new pedestrian/bicycle bridge. This bridge by itself is likely to cost in the ball park of $3 million, which would be too large for the TAP. Continuing the trail along the east side of the channel and connecting to Buttermilk Falls would be more like a $6M total project cost. However, in the past, when we have discussed this project with the New York State Department of Parks, Recreation and Historic Preservation, the main sponsor of the BDT, it seemed likely that they would be able to provide some level of funding for the trail and its associated bridges (a total of 3 needed in the City). Mostly, we wanted to keep this project on our radar whenever funding opportunities arise, but if the Board would like us to pursue this project, we will reach out to NYSPRHP to see if we can assemble a project. Except for the cost, we think this project would be eligible and competitive. Applications are due June 11, 2014. If the BPW can take action at their meeting on April 28th, we can proceed to a committee of Common Council in May and to the full Council in June before the application is due. At this point, our staff recommendation would be to pursue the Cascadilla Creekway project. Combining the desire to rebuild the small pedestrian bridge, with the need to replace the railings, with the Bicycle Boulevard and considering the usage this way gets, and the community support such a project would receive, this project looks to be competitive and compelling.

Sarachan, Assistant City Attorney Krin Flaherty, Assistant City Attorney Jared Pittman, Assistant City Attorney Jody Andrew, Executive Assistant Telephone: 607/274 -6504 Fax: 607/274 -6507 Stormwater Task Force Fact Sheet Proposed Legislation Concerning Stormwater Infrastructure Management and Financing • Summary of Current Context and Polia. o Stormwater management is a major expense for the City. We are situated on a lake, traversed by streams and inlets, at the base of many hills whose runoff comes our way. Stormwater consumes the better part of a million dollars of the budget each year on everything from storm sewers and channeled streams to environmental management and regulatory compliance. Flood control — including pressing issues like ice jams and dredging —is ultimately a question of stormwater management too. Stormwater runoff also has major environmental impact. o Currently, the City's stormwater program is funded primarily by tax dollars, not by the City's major tax- exempt owners, and not in a manner that accounts for the expected runoff generated by each property. Beyond regulation of construction sites and new development, the City Code provides few meaningful incentives for reducing runoff from existing properties. o For these reasons, in September 2013 the Mayor convened a Stormwater Task Force, chaired by the City Attorney, to address these problems and report recommendations to the BPW, and ultimately to Council. • Task Force Objectives for a New System of Stormwater Manaizement Financing. • Improved incentives for reducing stormwater runoff from each property: • Incentivize permeable surfaces: gardens, lawns, green roofs, etc. • Disincentivize impermeable surfaces: extensive paving, expansive roofs. • Shared cost burden of program in proportion to each property's expected runoff ■ Large parking lots contribute more than small gardens. • Inclusion of tax- exempt owners in a new system of financing. • Dedicated funding for current and future maintenance and regulatory obligations. • Creation of Stormwater Management User Fees. o The Task Force recommends the creation of a citywide Stormwater Management User Fee ( "the Fee "), based on the square footage of impervious surface per lot, a metric that is already recorded in the City's GIS database for each lot in the City. o The Fee will be billed to each property — whether tax- exempt or not —in quarterly increments, in conjunction with water and sewer bills where applicable. • Proposed Stormwater Management User Fee Formula. o The proposed formula uses as its starting point the concept of an Equivalent Residential Unit ( "ERU "), calculated as the average square footage of impermeable surface on a residential lot. As calculated, 1 ERU = 2,300 sq. ft. o The proposed formula entails three categories of properties: ■ Stormwater- Exempt Lots: those lots containing less than 0.25 ERU's of impermeable surface. Proposed Annualized Fee: $0. ■ Low Runoff Residential Lots: one -, two -, and three - family residences, all assumed to contain 1 ERU. A lot's eligibility will be determined by the Property Type Classification Code assigned to it by the Tompkins County Department of Assessment. These codes are established by the New York State Office of Real Property Services. Proposed Annualized Fee: $48. ■ All Other Lots: this category is proposed for treatment in two sub - groups: • Lots containing 0.25 –1 ERU. Proposed Annualized Fee: $48. • Lots containing in excess of 1 ERU. Proposed Annualized Fee: $48 per ERU, assessed in 0.25 ERU increments (i.e., $12 for each 0.25 ERU or portion thereof). ■ Credits: The "Other Lots" formula could also reflect credits against Fees. The Task Force expressed interest in #1, 4, 5, 8, and 9 on the attached list. • Determination of Budget and Expenditure Eli ibg ility. o The proposed assessment formula is estimated to raise a total of approximately $800,000 ( +/- $50,000) per year, roughly equivalent to the existing budget. o Tax- Exempt entities —not currently participating in the predominant funding source for the City's stormwater program — are anticipated to account for a sizable chunk of the program budget, including an estimated $130,000 Fee from Cornell. The City itself is estimated to be responsible for a $46,000 Fee. Large commercial spaces would substantially contribute as well; current estimates indicate a $12,000 Fee from Wegmans and a $15,500 Fee from Wal-Mart. o Expenditure Eligibility: The Fees collected will only be eligible for expenditure on any and all expenses deemed reasonably necessary to stormwater infrastructure and management in the judgment of the Superintendent of Public Works, as instructed from time to time by the Board of Public Works. A portion of the Fees may be maintained in an emergency reserve for stormwater- related expenses. o The anticipated legislation would preserve the right of the City (via Council, BPW, or Planning & Development Board) to require construction, maintenance, and repair of privately - maintained stormwater infrastructure at the cost of the property owner as part of site plan review or other applicable regulation. KJ Potential Stormwater Credit Program Options 1. Detention / Retention Credit: The detention/retention credit option is commonly offered by municipal stormwater programs to reduce total quantity of flow and/or rate of flow to an acceptable standard. Detention structures are designed to delay the highest flow from impacting the drainage system; retention facilities are designed to completely remove all flow from impacting the drainage system. Detention or retention facilities typically consist of small impoundments or dry ponds that collect runoff during wet weather events. Detention times vary with most being relatively short. Flow lengths are short and direct to outlet works, and depths vary depending on site conditions. To be eligible for this credit, the property owner would be required to construct and/or annually maintain the detention/retention facility. 2. Water Ouality Pond Credit: (Wet Pond/Extended Detention): Water quality ponds are used to improve stormwater quality, and control the quantity of flow and rate of flow. The ponds filter pollutants from the runoff which improves water quality; they detain peak flows, and extend detention time to control downstream runoff volume. Water quality ponds typically have long detention times and flow lengths. Ponds with design features such as permanent pools, settling bays, shallow wetland environments, aquatic plants, and shading of water from the sun can reduce pond maintenance, improve aesthetics and provide a habitat for wildlife. To be eligible for this credit, the property owner would be required to construct and/or annually maintain the water quality pond. 3. Vegetated (Stream) Buffer Credit: A vegetated buffer strip is a segment of concentrated riparian growth which lies adjacent to existing streams, rivers or other water bodies to reduce the impact of stormwater runoff on water quality, total quantity of flow and rate of flow. The buffer strips are designed to reduce or slow runoff, filter pollutants, reduce water temperatures through shading, protect and provide wildlife /aquatic habitat and reduce stream bank erosion. Design considerations include the placement and width of the buffer strip, the current condition of the stream/river, the surrounding habitat and soil conditions. Standardization of the definition of a "vegeteted buffer strip" is recommended to minimize conflict due to interpretation. Additionally, a conservation easement may be required to prevent future modification. To be eligible for this credit, the property owner would be required to construct and/or annually maintain the forested buffer strip. 4. Grass Filter Strip Credit: Grass filter strips are used to impact stormwater quality, total quantity of flow and rate of flow. The strips are comprised of uniform areas of dense turf or meadow grasses located along impervious surface areas with minimum slope such as parking lots or other paved surfaces. Designed to reduce or slow runoff and filter pollutants, the dense turf /grasses create a thick porous mat that dissipates small flows causing deposition and filtration of particulate. Design considerations include placement and width of the filter strip, the slope of the impervious surface area, the type of vegetation used and the range of flow volume and flow rate. Standardization of the definition of a "grass filter strip" is recommended to minimize conflict due to interpretation. Additionally, a conservation easement may be required to prevent future modification. It is recommended that property owners be required to annually maintain the grass filter strip once constructed to prevent excessive maintenance costs for the SUD. To be eligible for this credit, the property owner would be required to construct and/or annually maintain the grass filter strip. 5. Infiltration Trench Credit: (Open Channel) Infiltration trenches are used to impact stormwater quality and rate of flow. Correctly designed, constructed and maintained infiltration trenches are very effective instruments for stormwater management. However, care should be taken to ensure that the location of the infiltration trench is thoughtfully selected to prevent surface flooding. Stormwater runoff is collected in a trench filled with uniform graded stone for eventual re- absorption into the ground. This type of infiltration tends to reverse the hydrologic consequences of urban development by reducing peak discharge, increasing base flow to local streams, and providing filtration of stormwater pollutants and sediments. Design considerations include site conditions, soil conditions, slope, drainage area, maintenance issues, groundwater conditions, storage requirements, and area available for the facility. To be eligible for this credit, the property owner would be required to construct and/or annually maintain the infiltration trench. 6. Education Credit: Education credits can be provided to public and private schools (elementary through high school) that provide an approved water management education program to students. Schools that include educational programs on stormwater, flooding, water quality, and watershed management issues will enhance and expand public outreach and education activities of the SUD. To obtain this credit, public and private schools would incorporate a water curriculum in each grade level. Programs such as "Project Wet" developed by the Ohio Water Education Program or "Project Water - Wise" implemented through the Georgia Water Wise Council are examples of kindergarten through twelfth -grade water - related curriculums. 7. Disconnection of Impervious Area Runoff Credit: Disconnection of impervious area runoff credits are used to impact stormwater quality, total quantity of flow and rate of flow. Runoff from impervious surfaces such roofs and paved areas are disconnected from the municipal system and redirected to pervious areas for ground infiltration or soil filtration. Runoff from the disconnected areas are typically directed to promote overland vegetative filtering or use of bio- retention or infiltration areas to encourage soil infiltration. Design considerations include site grading, site conditions, roof area and slope. Also, it is recommended that area permeability, size and distance from the municipal system are defined and standardized to minimize conflict due to interpretation. To be eligible for this credit, the property owner would be required to disconnect the impervious area from municipal system, redirect runoff flow and annually maintain the drainage area. 8. Constructed (man -made) Wetlands Credit: Constructed (man-made) wetlands credits are used primarily to impact stormwater quality, typically in conjunction with other stormwater management practices. For example, constructed wetlands may be used to enhance a wet (detention) pond either as a shallow aquatic bench or wetland fringe to heighten the performance of water quality treatment. Wetlands treat stormwater runoff primarily through gravitational settling and stabilize the deposited sediment; however, they can also treat stormwater in ways most other treatment practices cannot, such as through plant uptake, absorption, physical filtration, microbial decomposition and shading. These credits are not offered for natural wetland areas because such areas are, by definition, "receiving waters ". Design considerations include the drainage area, surface area, wetland depth, vegetation, planting layout grading, and flow length. To be eligible for this credit, the property owner would be required to construct and annually maintain the constructed wetlands. 9. Swales Credit: Credits for swales are used primarily to impact the rate of stormwater flow, but can also impact stormwater quality and total quantity of flow depending on swale design. These small grass channels convey stormwater from impervious areas or between stormwater management practices. Swales are typically constructed in shallow areas with low runoff velocity; however, some swales may retain runoff and provide some pollutant filtration benefit. Design considerations include runoff flow velocity, swale width and slope. It is recommended that property owners be required to annually maintain swales once constructed to prevent excessive maintenance costs for the City. To be eligible for this credit, the property owner would be required to construct and maintain the swales. 10. Direct Discharee Credit: Direct discharge credits are used to account for situations where a property does not connect to or use the SUD system or facilities. These credits may be provided to properties that discharge stormwater runoff directly into a major natural stream without use of the municipal stormwater infrastructure system or municipal maintenance services. Other situatiosn for this credit could occur at the boundaries of the SUD jurisdiction. It is recommended that direct discharge credits are reviewed on a case -by -case basis to investigate the potential downstream impacts each direct discharge may have on the City's stormwater management system, particularly the water quality of the receiving body. Friends Stewart Park �111U Memorandum April 22, 2014 TO: City of Ithaca Board of Public Works FROM: Friends of Stewart Park RE: Spring & Summer 2014 Park Improvement Projects The Friends of Stewart Park (FSP) is working with the City on numerous small projects to enhance the park during 2014. Following are some of the projects we would like to pursue this spring and summer which we believe require BPW review and approval: • Large Pavilion Restrooms: Friends received a $70,500 grant from the Tompkins County Tourism Program (administered by TCAD) for improvements to the Large Pavilion (Picnic Pavilion). We have $20,000 in hand at the Chamber of Commerce with a commitment for an additional $50,500 over the next 3 years. It was recently discovered by the City that the bathrooms are in need of emergency repair. FSP is offering to use this funding to repair and renovate the bathrooms, which need to be done on a fast track, ideally by the end of June when the Day Camp opens. This has been discussed with Tom West, Ray Benjamin, and Jeanne Grace. Tom West is now taking the lead on project design using a layout prepared by Claudia Brenner (paid for by the Stewart Park Rehabilitation Action Plan). Friends is working with the City Attorney and TCAD to determine how to transfer funds and secure the future payments for city use. And Friends would appreciate a role in reviewing plans and materials selections as the process proceeds to ensure that the renovations are fitting of this important historic building. Stewart Park Entry Planting: FSP recently submitted a grant request to the Ithaca Garden Club for new planting at the entry to Stewart Park. The Garden Club funded and designed the Mayor Stewart Memorial Flagpole Garden (see photo below) and FSP Board member Beverly Hillman who is a long time Garden Club member led the design effort for this project, with the assistance of FSP Board members Miguel Berrios, a Landscape Architect who works part time for the Community Beautification Program and Annette Marchesseault of Trowbridge Wolf Michaels Landscape Architects. The plan and some images are attached. This planting was presented to the Parks Commission earlier this month and the Commission spoke favorably about the design. The garden will be installed by the Friends of Stewart Park and volunteers and maintained by the Community Beautification Program and FSP. Note that final grant selections will be announced in May. If successful, we would like to install this garden in May or early June of 2014. Phase 2 of the proposed park entry improvements may include a new sign — designs are to be developed. y • Stewart Park Trailhead: Plans for the construction of a Waterfront Trail Trailhead in Stewart Park have been in place for a few years. Last year partial funding was provided by the Legacy Foundation and numerous Stepping Stones have been pledged. The Cayuga Waterfront Trail Initiative is about to begin a Finish It — Furnish It Campaign to raise needed funds for this trailhead and Phase 2 promenade around the NYSDOT site that will include installation of 10 CWT benches and the Crew Cove Overlook. The Parks Commission also reviewed trailhead plans at its April meeting and it has been discussed at a CWT Client Committee meeting. Joann Cornish will lead a Planning Department review of this small project, which will include a semi - circular brick plaza and adjacent smaller semi - circular concrete plaza for the trail kiosk. Plans are attached. • Renwick Wildwood Interpretive Panel: FSP and CWTI have been working with the Cayuga Bird Club for nearly 2 years developing an interpretive panel on the history, habitat and birds of the Renwick Wildwood (commonly known as the Fuertes Bird Sanctuary). This sign, including research, design, fabrication and installation is being paid for in full by the Cayuga Bird Club ($5,500 + / -) and will be dedicated on June 8. It is to be placed along the boardwalk that connects the two pedestrian suspension bridges at the southwest corner of the park. A final draft of sign is attached. Ot X00 *s . i �T There are many other activities underway in the park by a variety of organizations. The Ithaca Motion Picture Project has developed beautiful building signs, also being presented tonight. The City, with FSP and Cascadilla Boat Club, assistance is working on an exterior stair to the Cascadilla Boathouse 2 "a story gymnasium. The City has created a $250,000 ( + / -) capitol project for park building roofs. The Tea Pavilion (Small Pavilion) was opened last year and is nearing completions, with rails just installed during the past week. Friends of Stewart Park would also like to paint the exterior of the Concession building by the end of June 2014. While long- term plans for this building are not clear at this time, we believe it would be an easy volunteer paint that would visually enhance the park. FSP currently uses this building to store gardening and maintenance tools. Thanks for your consideration and support.
