June 24, 2013 8.1A Authorization for Use of City Property at 1013 West State Street The resolution approving the lease of city property will be provided at the meeting. It will reflect the discussion the Board held on June 10, 2013. 8.2A. Authorization to Enter in a Memorandum of Understanding with Cornell University concerning Improvements to the Intersection of East State /Martin Luther King Jr. Street and Mitchell Street — Resolution This is the second project agreement for this project; the first you've authorized with Valentine Vision Associates, LLC (the project developer for the Collegetown Terrace project). The project has been on the Cornell /Community Transportation Initiative for a few years now and this agreement will formalize the funding. A few final plan sheets for the project are included for your information. The full set is out to bid currently and can be downloaded at www.citvofithaca.org /bids if you are interested. Otherwise, you will be asked to award the construction contract on July 8 th 8.213 Authorization to Acquire Real Property at the Intersection of East State /Martin Luther King Jr. Street and Mitchell Street — Resolution In the course of this project, staff discovered that the property at 904 East State /MLK Jr. Street actually owns a small portion of where the street, curb and sidewalk are constructed on the corner with Mitchell Street. We've found a drawing from 1924 showing the intention at the time to convey the corner to the City so that the public infrastructure is all in the street right -of -way; however, we've not found any records that the conveyance was executed. Luckily, the adjacent property owner has been cooperative and we'd like to finally finish up what we started some 90 years ago. 8.2C Award of Contract for Professional Services (Construction Inspection) for East State /MLK Jr. Street and Mitchell Street Traffic Signal — Resolution Creighton Manning Engineering, the design engineer for the project, has declined to provide construction inspection services for the project. Staff asked for three proposals and is recommending Erdman Anthony, with whom we are currently working on the Floral Ave trail construction. 8.4A Award of Bid for a New Ice Resurfacer — Resolution Bids have been received for the purchase of a new Ice Resurfacer for the Cass Park Ice Rink. Staff has provided their recommendation and a proposed resolution to award the bid. 8.5A Hangar Theater Water Account — Resolution A resolution is provided that reflects the decision made by the Board during their discussion on June 10, 2013. 9.1 Cascadilla Creek Walk Per the Board's request, Council members and neighbors of the creek walk have been invited to attend this Board meeting to discuss the project. Page 3 9.2 Appeal of Sidewalk Repair Requirement for 116 Kelvin Place The property owner has submitted a letter and photos regarding the sidewalk adjacent to the property. 9.3 Transportation Enhancement Program (TEP) funding — BPW recommendation This is the last round of what we have known as the Transportation Enhancement Program. Under the new federal law, MAP -21, the TEP will be collapsed with other programs into the Transportation Alternatives program. In the meantime, NYSDOT has some leftover funds and has put out a call for projects. Staff is looking for some direction and for a recommendation to Common Council, who will need to commit the local share of funding. 9.4 Proposal for Sixty Foot Dam — Dam Stability Analysis A proposal from O'Brien & Gere is enclosed for improvements to the Sixty Foot Dam, as required by NYS Department of Environmental Conservation Dam Safety Division. 9.5 Board Meeting Schedule Calendars for 2013 and 2014 are provided for the Board's review. Beginning in July 2013, the calendars are marked with two Board meetings per month. There are two months each year that a Monday holiday falls on either the second or fourth month, so only one Board meeting would be scheduled. You might want to consider scheduling an extra meeting for those months in advance. FOR YOUR INFORMATION: 10.1 American Public Works Association "Managing Infrastructure" Article Attached is an article from the recent copy of the American Public Works Associations' monthly publication concerning managing public works. I thought it was interesting for you because it is what you are doing as members of the BPW, because it is what you expect from your senior staff in the department, and because you are currently looking for a Superintendent who will head up the task of "Managing Infrastructure ". The article is a clear overview of what needs to be done, without prescribing how it needs to be done (unfortunately, but understandably). I suggest that is the question you should be asking staff as the budget comes before you. Does the budget support these goals, and the objectives required to meet those goals? How can you accomplish what needs to be done? While I believe that the department is well equipped to answer "what, where and how ", that does not mean they are equipped and funded to do it. That makes the management trickier, and more important. We have proven over the last ten years that the infrastructure was strong enough to wait, but that will not be true forever, and the quality of the infrastructure and its level of service is slowly deteriorating. — W.Gray 10.2 Ithaca Journal "High carcinogen level found in Lansing Drinking water" Article A head line in the June 12, 2013, Ithaca Journal was about carcinogens in Lansing drinking water. I have attached the article and the Wikipedia entry for trihalomethane. A few years ago we were the subject of a similar article. Next year, as the new regulations on disinfection by- products takes effect, I expect you will see more articles locally, and state wide, as system operators have to deal with new reduced levels of contaminants. Chlorine is the common disinfectant used by most water systems. It is a cheap and effective disinfectant because it is a highly reactive agent. This also means it will react with almost anything in the water. I believe all chlorinated organic materials are considered carcinogenic, if the exposure is long enough or at high enough levels. While we have dead ends and quiet areas in our water system where water sits longer and has extended exposure to the chlorine which creates Page 4 trihalomethanes , our system is much more compact than Bolton Point's. Clean water which is disinfected, and maintains a residual level of disinfectant to protect the water will have the potential for this problem, no matter the age of the water treatment system. The water plant and the distribution system operators will have to work together to control this problem. As we learn more there may be opportunities to work jointly with Bolton Point in the future to control the levels of contaminants in both systems.

State /MLK Jr. Street and Mitchell Street Traffic Signal and Roadway Improvements, and WHEREAS, in the course of the project, it was discovered that the property at 904 East State Street includes a portion of the street and sidewalk area, and that, though the City of Ithaca and the owner of that property in 1924 had intentions to transfer the land to the City, there are no records of that transaction transpiring, and WHEREAS, the current owner of 904 East State /MLK Jr. Street is amenable to a lot line adjustment in order to sell the corner of her parcel (approximately 190 square feet) to the City of Ithaca to be included in the street right -of -way, now therefore be it RESOLVED, That the Superintendent of Public Works is hereby authorized to execute any and all documents in order to complete this transaction, following consultation with the City Attorney, and that any compensation shall come from the authorized capital project and to be negotiated by the Superintendent.

Page 10 JULIE SIMMONS -LYNCH 116 KELVIN PLACE ITHACA, NY 14850 607 342 -4414 JULIESIMMONSLYNCH @CMAIL.COM June 11, 2013 Department of Public Works Ithaca, NY 14850 Dear DPW board members: Back in the late summer of 2012 I contacted Lynne Yost in the civil engineer's office about two major ruptures on the sidewalk in front of our home: both were caused by city trees' roots buckling the cement. I was told we'd be put on a tree removal list and that the city had "an informal practice of taking responsibility for broken sidewalks." After months of no response, I contacted Ms. Yost again. I know the city is a big, small city and our issue was not paramount but nonetheless, as time went on, one of the trees began to tilt toward our home and it wasn't until I voiced concern, that Dave Hoaglin ordered the tree to be removed. Jeanne Grace ordered the removal of the second tree soon after. What's left are two sidewalks, destroyed by these city trees. The roots have broken through and /or lifted the cement and they are very hazardous to pedestrians. (Please see photos.) We have since received a summons threatening surcharges, etc., if we don't repair the sidewalks. When I inquired I was told that the city no longer had their "informal practice of taking responsibility for broken sidewalks." How can that be? Why wouldn't the former practice, the one I was told was in place, be grandfathered in to allow for the city to fulfill their original policy? Why should we be penalized because it took many months for the city to remove their trees? Needless to say, these repairs would be a hardship for us, but I'm having a real problem with the principle of the request. If the city has taken responsibility for their trees, and has removed them before they cause more damage, then why isn't the city also responsible for the damage their trees have caused? If we, as homeowners, dropped a ton of bricks on the sidewalk, destroying the walkway, we would fix it as we should. It would be our responsibility. As a matter of fact, we were told by a city official that a line of shrubs on the border of our property was unruly and impeded access to the sidewalk - -a great exaggeration, I assure you- - but nonetheless, we addressed the situation and removed the shrubs swiftly. Most of the city officials I have discussed this with have been thoughtful and tried to help as best they could but now we are at a stalemate. 2 /Simmons - Lynch, 116 Kelvin Place The bottom line is the sidewalk is city property trafficked throughout the day and very dark night by people who are not accessing our property. They are people walking their dogs; children skateboarding; tenants from the nearby senior assisted - living facility, Bridges. I am asking the city to do what's right; to do what you said you would do; to do what we pay property taxes for; and that is for the City of Ithaca to take responsibility for what is yours. I look forward to hearing from you. With very best wishes, Julie 9igirall"ignedby Julie Simmom- ira�h SifTlfTlon$- Jmkslmman:�m�b,a, ma ikjes257@comell.edu.

In this round of funding, proposed projects must cost at least $200,000 and based on guidance from our regional NYSDOT office, the largest project is likely around $600,000 of federal -aid, which would make for a total project cost of $750,000. The local match needs to be approved with the application (contingent on award is ok), so if the City is going to pursue a project, we need Common Council to commit the local share. Staff is looking for guidance on which project to pursue and will need a recommendation to Common Council for funding. Workloads in the office are extremely high right now, so if we do not pursue this opportunity, we can live with that. Applications must be submitted by August 16th and project awards will likely be in late 2013. We would want to make it on to the August Common Council agenda for approval. If the BPW can provide us some direction on June 24th, that will give us a little time to better scope out the project and to prepare cost estimates to present to Council. Our top five project ideas (in order of what we think is most promising) are: Pedestrian and bicycle improvements on West State /MLK Jr. Street, between Floral Avenue and Fulton Street. The scope of work could include a new mid -block pedestrian crossing signal across West State /MLK Jr. Street between the bridge and Brindley Street, Page 1 of 3 'An Equal Opportunity Employer with a commitment to workforce diversification." �� as well as a "road diet" along Rt. 79 between Floral Ave. and Taughannock Blvd, by reducing the 4 lane section to 2 lanes, plus turn lanes, and adding bike lanes. a. Pros: i. This project would address the difficulty that pedestrians have in crossing this busy (approx.15,000 ADT), 4- lane -wide street. ii. Improve bicycling conditions iii. Reorganizing and reducing the driven lanes could improve safety and operations as well, by reducing unnecessary weaving and passing. b. Cons: i. New pedestrian/ traffic signal will have long -term energy and maintenance costs. ii. This project would not contribute funds to any existing maintenance needs 2. Creekway enhancements along Cascadilla Creek, between Cayuga Street and Aurora Street. The scope of work would include replacing all of the pipe railings ( -1,600 If) with attractive railings that meet current safety standards and repair top edge of creek walls. Redesign of the driveways/ intersections at Aurora St, Tioga St, and Cayuga Street may allow for some enhancement, too. Different paving materials might be possible, depending on budget. Interpretive signs could be included, too. a. Pros: i. The existing pipe railings are woefully substandard and the large openings afford little protection, particularly to children. This is an existing deficiency that the City should plan to correct, yet funding such improvements in a comprehensive manner with City funding alone is unlikely. ii. A new railing could include interpretive elements to recall the history of this area including the original railing design. iii. The new railing would enhance the beauty of this area. iv. Improve conditions for pedestrians and bicyclists v. Implement a portion of the City's Bicycle Boulevard Plan. b. Cons: i. Though clearly substandard, it is unclear whether there is any history of injuries related to this railing; therefore, this may not be a priority at this time. 3. A new sidewalk project. Viable options for the scale and complexity of the program could include: • Hector St from Vinegar Hill to Fallview Terrace, or possibly Oakwood Ave. We would need a significant "over" match from the City to get to the City line. • One side of Coddington Road and the 700 block of Hudson St • South Meadow Street Extension from Old Elmira Rd to Spencer Road (and maybe the segment of Spencer Rd to Stone Quarry Rd) a. Pros: Page 2 of 3 i. TEP funding would allow progress on a large new sidewalk project where City funding alone is unlikely. ii. The City's required 20% match could be partially reimbursed by sidewalk assessments to adjacent property owners. iii. TEP funds could go to reconstructing an existing sidewalk segment. This could be particularly useful where costly retaining wall work is needed. b. Cons: i. The City's required 20% match could be partially reimbursed by sidewalk assessments to adjacent property owners. 4. Advance a portion of the Stewart Ave. reconstruction project. Partnering with Cornell, we might do a segment from Campus Road down to approx. Williams Street. Or we could go after the first two blocks coming up from State /MLK Jr. street (might get to Buffalo Street, but might need a larger match from the City). a. Pros: i. This project is in dire need of non -City funding due to its high estimated costs. TEP funding would allow the City to make needed repairs and would allow the City to construct the desired functional and aesthetic enhancements. ii. The fact that plans have already been drafted for this project will likely increase its competitiveness. b. Cons: i. As the Stewart Ave. project is estimated to cost —$6.5 million, the TEP funding would only be able to address a short portion ... perhaps too short of a portion to be worthwhile. Pr jects that we considered, but which do not seem to be good candidates include: - Reconstruct the walkway along Cascadilla Park Rd. between University Ave. and Stewart Avenue. The TEP requirement to meet federal walkway design standards may be at odds with resident preferences. - Construct the final leg of the Six-Mile Creek walkway from the recent stone dust trail behind the Gateway Commons building, across Six -Mile Creek, to the base of the stairs under the Columbia St. Pedestrian Bridge; at least one bridge would be needed. This project leans more toward recreation than transportation ... the Recreational Trails Program (RTP) (administered in NY by OPRHP) seems like a more suitable funding option. In any case, this trail project is probably a low City priority. Page 3 of 3 Item 9.4 Proposal for Sixty Foot Dam- Dam Stability Analysis Discussion Item for June 24 BPW Meeting From: Erik Whitney, PE, Assistant Superintendent DPW, Water & Sewer Division Contract #1 of our City of Ithaca Water Supply Project — "Sixty Foot Dam & Reservoir Improvements" will entail work on the existing dam and permitting of this work through the New York State Department of Environmental Conservations Dam Safety Division. This work will entail a replacement of the existing gatehouse and intake structure as well as replacement of the low level outlet valve. The Dam Safety Division will also be concurrently reviewing and making their recommendations on our Dam Engineering Assessment. The Engineering Assessment (EA) of the Potter's Falls (60ft) dam was completed by CT Male and submitted to DEC Dam Safety on 8/22/12. We have not formally heard back from NYSDEC Dam Safety as to what they will finally require of us with regard to the 60 -foot dam. CT Male's recommendations were reviewed by O'Brien & Gere's dam engineers. Some of those improvements, especially to the low level outlet and gatehouse are being incorporated into the Water Supply Project. CT Male has also recommended in their report that a dam stability analysis be performed. In talking with NYSDEC Dam Safety Unit personnel we understand that this will be required of us. The final outcome of a dam stability analysis could certainly result in us having to pin the dam to the adjoining bed rock with grout anchors, or other structural reinforcement. At any rate it would be very prudent of us to have the dam stability analysis performed and know what the requirements for reinforcement of the 60 -foot dam will be before we start the Water Supply Project work at that location. This is true for at least two important reasons: First, NYSDEC Dam Safety will likely be adverse to entertaining our permit application for work on the Dam if it only includes the gatehouse and low level outlet replacements without also addressing the potential need for structural reinforcement to meet the present day loading and stability requirements. Second, we will be staging the area and dewatering the dam face to construct the improvements necessary for our Water Supply Project, while we have the contractor in there it would be far less expensive to do whatever pinning or structural reinforcements which maybe finally prescribed by Dam Safety. Please reference attached proposal from O'Brien & Gere for Sixty Foot Dam - Outstanding EA Tasks, dated March 5, 2013. I would recommend that we engage these services from O'Brien & Gere and incorporate their findings and subsequent designs into our Contract #1 before bidding. Funding for this would be derived from the contingency funds allocated for the Water Supply capital project. I would like to put together a resolution to accept OB &G's proposal at our next meeting. Rick Gell can be present at the July 1, BPW meeting to answer any questions in greater detail. a CYBRIEN 6 GERE March 5, 2013 Mr. Erik Whitney City of Ithaca - Water & Sewer Office 510 First Street Ithaca, NY 14850 RE: Proposal for Sixty Foot Dam - Outstanding EA Tasks FILE: 1598/42988 Dear Mr. Whitney: As anticipated and discussed in our meeting at the WWTP office on October 22, 2012, the New York State Department of Conservation has raised a number of comments on the CT Male Engineering Assessment (EA) Report dated 12/14/12 (attached) that need to be resolved before the NYSDEC will accept the findings. As requested by the City, O'Brien & Gere is pleased to submit this proposal for addressing all of NYSDEC's comments in the 12/14/12 letter. Coordination of potential dam safety related dam upgrades with the water supply project will be efficient and result in less disruption to the operation of the reservoir. SCOPE OF SERVICES TASK 1- HAZARD CLASSIFICATION & INCREMENTAL ANALYSIS NYSDEC indicates that the CT Male EA is absent a conclusion regarding the dam's hazard classification. Examination of Six Mile Creek through the City strongly suggests that Sixty Foot Dam should remain classified as High Hazard. The EA report states that a HEC RAS hydraulic model of Six Mile Creek was developed to prepare inundation mapping for the dam's Emergency Action Plan. We propose reviewing the inundation mapping and HEC RAS model, if available, to support the High Hazard recommendation. Once the review is complete, O'Brien & Gere will prepare a description of the hazard area, the downstream impacts from dam failure and a recommendation for the hazard classification. There may be a potential benefit from an incremental analysis of dam breach versus flood elevations downstream of Sixty Foot Dam to reduce the loading on the dam for the Spillway Design Flood (SDF) loading condition. Normally, in a dam of this height, the difference between tailwater elevations for the pre- and post - breach scenarios obviates this analysis. However, CT Male has reported a very high tailwater elevation and discharge for the SDF such that the addition of a dam break discharge to the SDF hydraulic grade line may not have a significant downstream impact. Therefore, O'Brien & Gere will use either the CT Male HECRAS model, or develop its own model, to assess the potential of an SDF reduction. The results of this analysis will be presented in our report. TASK 2 — EMERGENCY ACTION PLAN REVIEW NYSDEC indicates that the CT Male EA is absent discussion regarding review of the adequacy of the existing EAR Therefore, O'Brien & Gere will undertake this review and report on same. 333 West Washington Street, PO 4873, Syracuse, NY 13221 -4873 1 p 315 - 956 -6100 1 f 315- 463 -7554 1 www.obg.com 360° Engineering and Project Delivery Solutions Mr. Erik Whitney June 19, 2013 Page 2 TASK 3 — STABILITY ANALYSES © 2013 O'Brien & Gere. All Rights Reserved. The CT Male EA recommends execution of dam stability analyses and NYSDEC has indicated that same is necessary for Sixty Foot Dam. O'Brien & Gere will review the background and assumptions for the previous stability analyses that were performed by Thomsen Associates and Stearns & Wheeler to establish the appropriate site geometry and material properties to be used for the proposed gravity dam stability analysis. The specific parameters to be developed include: Spillway and non - overtopping cross - sections Headwater and tailwater elevations Concrete unit weight Silt density and depth Foundation rock density n Friction factors at concrete lift joints, dam /bedrock interface, and bedrock bedding planes Shear - friction (cohesion) factors at above surfaces The analysis will be performed to obtain safety factors and resultant locations for sliding and overturning failure mechanisms, respectively. The applied load cases will include normal pool, normal pool with ice, maximum pool (SDF), and earthquake loading conditions as per NYSDEC dam safety regulations. Several additional iterations of the stability program will be run with variations of the key material and /or loading parameters (in addition to the base assumptions) to evaluate the sensitivity of the safety factors to these parameters. The previous SDF analysis will also be reviewed to assess whether an incremental dam breach analysis might result in a substantially reduced SDF (maximum loading condition) as described in Task 1. Additional geotechnical investigations and /or analyses may be recommended on the basis of these results, if it appears that refinement of certain parameters could make a significant difference in the outcome of the stability analyses. A finite element stability analysis may also be recommended as a more representative model of site conditions, although a pre - proposal evaluation indicated that the dam's radius of curvature is too large to transfer significant downstream thrust to the abutments. TASK 4 - REPORT O'Brien & Gere will prepare a summary report that responds to NYSDEC and presents the following: Findings of our review of the previous EAP inundation analyses and mapping Assessment of SDF reduction by incremental breach analyses Findings from our review of previous stability analyses Base assumptions for site conditions and material properties Results of the gravity dam stability analyses Results of the sensitivity analyses and conclusions regarding the merit of additional investigations and /or analyses Recommendations for future course of actions (response to NYSDEC review comments ?) 333 West Washington Street, PO 4873, Syracuse, NY 13221 -4873 I p 315 - 956 -6100 1 f 315 - 463 -7554 1 www.obg.com 360° Engineering and Project Delivery Solutions Mr. Erik Whitney June 19, 2013 ® 2013 O'Brien & Gere.
