Utilities Engineer Repp addressed questions asked by Chairman Wagner regarding the original consultant selection process. Utilities Engineer Repp spoke about the cost of the project and noted that there is an amount of uncertainty associated with the outcome of the project, so staff built into the tasks and schedule of the contract, the ability to oversee the project's progress and to give the City the ability to exit the contract, if needed. Utilities Engineer Repp discussed the assumptions that have been included in each task of the project's scope. Repp explained that due to the uncertain and indefinable nature of the project, staff included Page 2 of 10 task number 8, Additional Analysis. Utilities Engineer Repp reviewed the project's scope of work with the Committee, pointing out that developing a basin plan includes a lot of paper work as well as field work. Member Osborne asked if staff is aware of any possible objections to the basin plan from neighboring jurisdictions, and referenced page 3 of 10 of the scope of work handout. Utilities Engineer Repp answered that staff is not aware of any objections at this time. Repp explained what task 2, Stakeholder Coordination, will entail. Repp stated that the City of Auburn will be in attendance at the meetings between the consultant and the Department of Ecology, in response to a question asked by Member Osborne.

Utilities Engineer Repp responded to questions asked by Vice-Chair Peloza regarding the contract budget and the contract task schedule. Assistant Director/City Engineer Selle explained that the funds for task number 8, Additional Analysis, are being included in the amendment to use if needed, in response to a question asked by Vice-Chair Peloza. The Committee and staff reviewed the project scope of work. Utilities Engineer Repp addressed questions asked by the Committee regarding the individual tasks included in the project's scope. Chairman Wagner asked when staff will report back to the Committee for a progress report at the end of task 5. Utilities Engineer Repp stated that the purpose of the study is to determine whether or not Mill Creek is stable enough to accept stormwater discharge from selected sub-basins within the urbanized areas of the City, without detention, in response to a question asked by Vice-Chair Peloza. Assistant Director/City Engineer Selle clarified that stormwater will go into Mill Creek, even without detention ponds, and staff is trying to show through the study that additional water from future development or redevelopment will not cause erosion problems along Mill Creek. The Committee asked for a copy of the Mill Creek sub-basin map and the Mill Creek flow control sub-basin map to be provided to them. Utilities Engineer Repp answered a question asked by Vice-Chair Page 3 of 10 Peloza regarding the project funding source, the storm utility fund. Motion Carried Unanimously. 3-0. III. RESOLUTIONS A. Resolution No. 4821 A Resolution of the City Council of the City of Auburn, Washington, Authorizing the Mayor and City Clerk to Execute an Interlocal Agreement with the City of Algona to Design and Construct the Boundary Boulevard Resurfacing Councilmember Peloza moved and Councilmember Osborne seconded to approve to recommend that the City Council adopt Resolution No. 4821. Director powdy stated that the Mayor of Algona has asked that the Resolution be presented to the Committee and Council and considered for adoption. Director powdy stated that the City of Algona is proceeding with an annual chipseal project and would like to complete to project up to O Street, which is in the city limits of the City of Auburn. The interlocal agreement being presented to Council is for reimbursement to the City of Algona for chipsealing the portion of the project within the jurisdiction of the City of Auburn. Director powdy noted that the square footage in the agreement, page 2 of 5, number 6, is incorrect and will be amended to read "3363 Square Yards," and will be amended prior to going to the City Council for approval. Also, the estimated amount of Auburn's share of the project will be amended to $18,495. Director powdy stated that chipseal treatment will benefit the portion of the roadway along the northern half of Boundary Boulevard, in response to a question asked by Chairman Wagner. Director powdy explained that a consultant will likely be managing the project for the City of Algona in response to a question asked by Vice- Chair Peloza. Motion Carried Unanimously. 3-0. IV. DISCUSSION ITEMS A. Wholesale Water Purchase (Dowdy) Utilities Engineer Repp provided a brief summary of the purpose of the discussion which is to review the current water Supply-Demand Page 4 of 10 forecast and the estimated cost and benefits of options to meet the forecasted demand. Repp reported that City staff had met with Chairman Wagner to determine how to analyze and compare the different options available to the City. Utilities Engineer Repp discussed the options available to meet the forecasted "near term" customer demand with improvements to Well 1 and by purchasing permanent and/or interim water supply from either Tacoma Public Utility (TPU) or Cascade Water Alliance (CWA). Chairman Wagner asked why the Department of Health does not allow for new connections for options 2, 4, and 5, on the Water Supply Cost- Benefit Summary spreadsheet. Utilities Engineer Repp answered that options 4 and 5 are not permanent water supplies and options 2, 4 and 5 do not meet the need for current demand until 2013 or later. Chairman Wagner asked why option 5 would not be the best solution. Utilities Engineer Repp answered that there is no practical way to take delivery of the water. Mayor Lewis, the Committee and staff discussed the current agreement between Cascade Water Alliance and the City of Auburn, which allows the City to purchase interim water supply from CWA. Director powdy spoke about the importance of securing a permanent water source. Utilities Engineer Repp responded to questions asked by Chairman Wagner regarding the Supply-Demand Forecast graph. Repp explained that the City needs a substitute for the largest source of water out of service and the way the system is being constructed one of the interties off of Pipeline 5 would be used for emergency situations. Director powdy reviewed the Supply-Demand Forecast graph with the Committee, stating the City plans on developing as much of the water rights as it can afford but at this time the City needs to look at other options to be above the demand line so that we can obtain State Department of Health approval of the Water Comprehensive Plan and the City can avoid a moratorium on new water connections. Utilities Engineer Repp responded to questions asked by Chairman Wagner regarding the cost of SDCs for option 4 on the Water Supply Cost-Benefit Summary spreadsheet. The Committee and staff discussed what would constitute an "emergency", the City's existing emergency interties and why these Page 5 of 10 are not considered permanent sources of supply for purposes of meeting projected customer demand. Assistant Director/City Engineer Selle explained that staff is recommending purchasing water from TPU in order to move the City above the demand line, thus allowing the City to develop other sources and consider more cost effective future water options. The Committee and staff discussed the costs of purchasing sufficient water from TPU. The Committee made recommendations for updates to the Cost- Benefit Summary spreadsheet. The Committee and staff discussed the cost and ability to pump water up Lea Hill. Utilities Engineer Repp responded to questions asked by Member Osborne regarding the production cost summary table on the Cost- Benefit Summary spreadsheet and the breakdown of the City's operational cost. Staff will present the Committee with the updated spread sheet, TPU water purchase agreement and Resolution for action at the next Public Works Committee Meeting. B. Speed Limit, Signage and Signal Timing to Preserve Arterial Pavement (Para) Traffic Engineer Para reported that citywide there is an existing code for trucks and weight restrictions of 15 tons for non-local traffic and the number of existing notice signs posted will be increased primarily at the gateways to the City. Staff answered questions asked by Chairman Wagner regarding enforcement of the weight restriction. Traffic Engineer Para reported that inspection of the worst pavement sections has been completed and on three roads reduced speed limits have been implemented. Assistant Director/City Engineer Selle explained that based on pavement condition and staff assessment, to make the roadway safer for the traveling public, the speed limits were reduced in some corridors, in response to a question asked by Member Osborne. Assistant Director/City Engineer Selle explained why speed itself does not cause of pavement deterioration, but rather the number of trucks and loading of trucks is the overwhelming factor for Page 6 of 10 deterioration. Director powdy reiterated that the reduction of speed will address safety issues, which is why speed reductions must apply to all traffic. Chairman Wagner asked on which roads was speed reduced. Traffic Engineer Para answered West Valley Highway between Main Street and just south of 15th Street NW, West Main Street between West Valley Highway and the Interurban Trail, and 37th Street NE/NW between West Valley Highway and Auburn. Traffic Engineer Para stated that the speed limits are being reduced from 45 mph to 35 mph on West Main Street, in response to a question asked by Vice-Chair Peloza. Assistant Director/City Engineer Selle said on 37th Street NE/NW the speed limit is reduced from 40 mph to 30 mph and confirmed that no limits are being reduced to 25 mph. Assistant Director/City Engineer Selle stated another roadway that staff may also propose to reduce is East Valley Highway from 37th Street SE to the Lake Tapps Parkway, from 40 mph to 35 mph and then south of Lake Tapps the speed will be reduced to 30 mph. Assistant Director/City Engineer Selle stated that staff is also proposing to increase the frequency of the 35 mph speed limit signs along the Lake Tapps Parkway for emphases. Traffic Engineer Para stated that signal timing on three of the signals in Lakeland Hills will be adjusted to favor local traffic. Assistant Director/City Engineer Selle explained that the signal timing at Lakeland Hills Way, Old Man Thomas Road and 16th Avenue along Lake Tapps Parkway will be adjusted to allow local drivers better access. Assistant Director/City Engineer Selle said the timing may affect commuter traffic moving through the corridor but it will greatly benefit Auburn residents. Assistant Director/City Engineer Selle stated that the changes will be monitored and if necessary adjustments will be made to accommodate Auburn's traffic needs, in response to a question asked by Chairman Wagner. Member Osborne asked if there are cameras to monitor the intersection. Traffic Engineer Para answered that there is one camera on Lake Tapps Parkway, but not at the intersections. Assistant Director/City Engineer Selle stated that staff will be monitoring the timing on site. Member Osborne suggested that staff make sure traffic flow is not Page 7 of 10 held up in both directions because the timing of a green arrow is too long. Chairman Wagner asked if there was anything else being done to preserve arterial pavement. Assistant Director/City Engineer Selle answered that these changes are just part of an ongoing process. Director powdy spoke about the new pilot program for repairing potholes that has been tested with a vendor. Director powdy reported that the new process appears to be fast, efficient, and cost effective and the patch quality is apparently very durable. The program will be further explored with City of Aberdeen to determine if Auburn can benefit from either lease or purchase the new type of Pothole paver. C. Roadway Striping Policy (Para) Traffic Engineer Para presented a map indicating the streets in the City that are currently striped on an annual basis. Traffic Engineer Para explained that the map identifies the roads which Pierce County striped and those that were striped by King County. Traffic Engineer Para reported that he completed a cost analysis of the work done by both counties and Pierce County's cost was a little higher than King County's. Para said that the Pierce County product, although higher in cost, is holding up very well. Pierce County uses a different type of paint than King County which may contribute to the better durability. Traffic Engineer Para said the strategy for the previous two years of pavement striping has been to try to maximize the amount of thermoplastic pavement marking by decreasing the amount spent on striping since the thermoplastic pavement markings are reaching the end of their useful life and need more maintenance. Traffic Engineer Para stated that there are locations that are currently striped for safety but most of the streets striped are main arterials, collectors and higher volume roads, which meet the basic federal requirements under the MUTCD. Chairman Wagner suggested the school bus routes be included in the striping program. Traffic Engineer Para pointed out that the school buses have over 100 routes and include almost every road in the City. Para explained that residential roads are usually not striped. Para stated that over the past few years he has been identifying the critical safety locations through the annual accident evaluation and monitoring, to find high accident areas that may benefit from added striping. The Committee and staff reviewed the map. Page 8 of 10 Member Osborne commented that it will benefit the City and future economic development to have well maintained striping, pavement markings, and c-curbs that look nice. Chairman Wagner asked that staff continue striping the Hidden Valley neighborhood due to bus traffic and recommended increasing the funding for the striping project for 2012 and 2013 by an additional $100K and asked that staff consult with the Mayor regarding the project budget. Traffic Engineer Para agreed that with the current funding, all of the pavement markings are not refreshed annually. Traffic Engineer Para answered questions asked by Vice-Chair Peloza regarding the use of thermoplastic. The Committee and staff discussed the possibility of contracting with Pierce County exclusively due to the durability of the paint they use. Traffic Operations Engineer Nutter discussed the differences between the paint King County uses versus the paint Pierce County uses and the differences in application and procedure. D. Capital Project Status Report (Gaub) Item 6— CP0909 — Lakeland Hills Booster Pump Station: Vice-Chair Peloza asked what the "head end" is. Assistant City Engineer Gaub answered that head end is the systems control center that is located at the Maintenance and Operations building. Item 8— CP207A — A Street NW Corridor Phase 1: Assistant City Engineer Gaub stated that the October 2012 date on the Capital Project Status Report indicated the end of the contract duration and not necessarily when the roadway will be complete enough to open to through traffic. Gaub said that the road will likely be open to traffic in the summer of 2012 but this is weather dependant. Item 23 — CP1107 — Fullmer Wellfield Improvements: Chairman Wagner asked when the investigative phase will be completed. Utilities Engineer Repp answered that it may be complete toward the beginning of 2013. Chairman Wagner asked to revisit the schedule for the project phasing at the next meeting. Item 34 — CP1121 — 2011 Local Street Pavement Preservation Phase 2: Assistant City Engineer Gaub stated utility work on H Street SE began last week in response to a question asked by Vice-Chair Peloza. E. Activities Matrix (Dowdy) Item A— Street Lighting: Director powdy stated the inventory is still Page 9 of 10 being worked on, in response to a question asked by Vice-Chair Peloza regarding the next review date for the item. V. ADJOURNMENT There being no further business to come before the Public Works Committee, the meeting was adjourned at 5:42 p.m. Approved this 4th day of June, 2012. Page 10 of 10
