C524A, SCADA SYSTEM IMPROVEMENTS PROJECT Project Engineer Lee stated that this project is a technology improvement project, where the design, software, hardware and construction costs are combined, in response to a question , asked by Chairman Wagner. Chairman Wagner pointed out that there is no competitive bid for the construction as there is with other projects. Lee explained that the contract value is based on negotiation between the City and the consultant consistent with other consultant contracts.° Assistant DirectoNCity Engineer Selle stated that the project scope involves technology enhancement where the consultant assures that the SCADA equipment is integrated with the software. How the system is set up to interface is very much dependenfi on the consultant's professional judgment and services. The project does not lend itself to a typical bidding process but is more appropriate for a design/build process. Chairman Wagner verified that Council has approved a budget of $4,099,621.43 for the project. Project Engineer Lee verified that to be correct and said tfiat is the "not-to-exceedn amount for the agreement. Vice-Chair Peloza asked if there is a full test of the system included in the agreement amount. Project Engineer Lee described how the overall system and each site will be tested. The contract is organized such that testing of specific phases of the installation wilf be approved by the City prior to. beginning the next phase of the system installation. Project Engineer Lee answered questions asked by Vice-Chair Peloza, stating that the - consultant will provide maintenance to the system until the complete new system is accepted by Page 1 Public Works Committee Minutes February 7, 2011 MINUTES the City. The consultant will provide training to staff as part of the contract. After completion of the new system, the City would need to determine the extent or need for a maintenance agreement with a consultant sirnilar to our current agreement with S&6 (current SCADA support vender). Vice-Chair Peloza asked that more detail regarding the design, software, hardware and construction cost allocation of the contract be provided to the Committee. Chairman Wagner agreed that more detail is needed and suggesfed postponing Council action until the detail can be provided by staff. Vice-Chair Peloza supported postponing action by the Council.

The Committee and staff discussed the amount of detailed cost information that can be provicled. In response to Vice-Chair Peloza, Project Engineer Lee verified that the project is funded by the utility funds: The Committee and staff reviewed the communications network map. Project Engineer Lee explained that the communication mode for the new SCADA system is wireless and will no . longer be reliant on land lines. Chairman Wagner asked what affect the bond funded SCADA project has on utility rates. ' Utilities Engineer Repp answered that staff did review the affect on the rate study. Repp explained that the amount of bond money in the fiscal analysis of the Capital Facilities Program (CFP) and rate study was higher than the actual $22M coming in from the Build American Bonds. Repp said that Finanee Director Coleman assessed the overall plan and the rate model and determined that the City could continue to meet its debt coverage and financial obligations associated with selling the bonds without impacting current utility rates. Chairman Wagner requested Finance Director Coleman and Utilities Engineer Repp provide the Committee with a summarized assessment of such at a future meeting separate from a future discussion on SCADA. Vice-Chair Peloza asked what company will be installing the system. Project Engineer Lee answered that the consultant will program and install the system. Utilities Engineer Repp said that one of the reasons staff selected this particular consultant and design team is because they have the ability to provide 24/7 maintenance as well as design and installation. Project Engineer Lee explained that a long term maintenance contract is not part of this Agreement No. AG-C-401 and that a future maintenance agreement:will be considered separately at the completion of the project. Chairman Wagner stated that the Committee needs some information as to the cost of maintenance, such as the affect of operating costs that are normally included in the CFP. Project Engineer Lee spoke about the security features. Vice-Chair Peloza asked if the new SCADA system will add security for the pump houses. Assistant DirectoNCity Engineer Selle answered that there will be security elements included at some of the facilities since the new SCADA system provides more flexibility to add security elements than the current system. Assistant Director/City Engineer Selle said that the scope of the project includes some initial security. enhancement at priority sites, but the system can be expanded in the future. Vice-Chair Peloza asked if there were any grant opportunities for the security elements of the project. Assistant DirectoNCity Engineer Selle stated that there are currently none, but staff monitors grant opportunities aggressively.

WEST VALLEY HIGHWAY IMPROVEMENTS PROJECT - WEST MAIN STREET TO SR18 - DESIGN UPDATE Project Engineer Sweeting distributed an aerial map of the West Valley Highway Improvements Project overview to the Committee. Sweeting stated that the West Valley Highway Improvements Project is a roadway improvement project between West Main Street and the ' SR-18 on ramp. Sweeting provided background information on the project. It was discussed that there is_a lot of southbound traffic that backs up during the peak hour, blocking the left tum pockef, creating safety concerns. There is also an outdated signal at West Main Street and West Valley Nighway, the roadway is in poor condition, and there are potential drainage issues along the corridor, which the project will also address. Sweeting reported that there was a Transportation Improvement Board (TIB) grant awarded that wilf fund up to $3,000,000 or 60% of the total project cost to improve the roadway. Project EngineerSweeting reviewed the scope of the project with the Committee. The roadway , will be widened, exfending the left turn pocket and a center median and center turn-lane will be added. The project also includes construction of a bicycle lane and a sidewalk on the west side of the roadway. The signal at West Main Street will be updated to the new signal standards and street lighting will be insfalled. The drainage issues will also be addressed. Chairman Wagner asked if major tree removal would occur on the hillside. Project Engineer Sweeting answered that the strategy for the hillside is to not disturb if as much as possible, however there will be some tree removal on the east side of the road related to relocating the existing roadside ditched, but the, trees will be replanted as part of the mitigation. Chairman Wagner asked if wetland mitigation is required. Sweeting responded that the project is not in a wetland area but it is in a wetland buffer area: There will be some on-site mitigation for impacts to the buffer area. ~ Sweeting stated that the construction of the ditches is being permitted through the Army Corps of Engineers, which may affect~the project schedule. Staff intends to go out to construction in Summer 2011, pending a timely response from the Corps to proceed. Project Engineer Sweeting described the new Low Impact Development (LID) stormwater management techniques,that will be used as part of the project. The project will include pervious concrete sidewalks on fhe west side, a bio-retention swale (rain garden) in the center median of the roadway, and a compost amended fill slope on the east side of the roadway. . Page 5 Public Works Committee Minutes February 7. 2011 MINUTES Sweeting answered questions asked by Chairman Wagner regarding how the stormwater will . drain into the swale in the center median and how the water will be treated as it drains into the ditch located on the east side. Assistant Director/City Engineer Selle responded that there are no requirements to monitor the water quality, but the City may decided to do some monitoring to determine the effectiveness of the new LID techniques being used, following questions asked by Chairman VVagner. , Project Engineer Sweeting reviewed the project schedule. Chairman Wagner asked if the Washington State Department of Transportation (WSDOT) has plans on extending West Valley Highway south. Sweeting stated that the proposed sidewalk . ends at the City Right-of-way and that#he City is working on extending the bicycle lanes/shoulder and channelization south into WSDOTs Right-of-Way. Project Engineer Sweeting reviewed the changes that will be made in channelization on West Valley Highway and turn lane modifications at the intersection of West Valley Highway and West Main Street. Sweeting spoke about the project's cost estimate. The City match for the TIB grant is being funded through the Street and Storm Funds. Chairman Wagner spoke in favor or using storm funds for this purpose given all the drainage aspects of the project. D.

CHAPTER 35.77 There were no additional questions or comments from the Committee. F. WELL PUMP DIAGNOSES Utilities Engineer Repp distributed a discussion outline and some maps and drawings to the - Committee. Utilities Engineer Repp explained that the wells that staff has currently been dealing with are Well 2 and Well 6. Repp reviewed the site map and pointed out the location of the wells: Both wells are located in the same building and are separated by approximately 33 feet. Utilities Engineer Repp continued with the well diagnoses summary. The Well 6 pump was shut down in October 2009 and staff pulled the pump and started analysis in November 2009 to try to determine why it stopped working. Well Z was showing similardeclines in production as Well 6 and staff shut it down on June 30, 2010. Staff enlisted the help of a consulting firm to assist in the analysis. The analysis of the pump included hydraulic, mechanical, chemical, electrical and corrosion components. Utilities Engineer Repp reviewed what was examined under each component during the analysis with the Committee. Repp spoke in depth about some of the things that can cause corrosion to these types of facilities. Referencing the drawing on the pump column, Repp discussed the findings for Wells 2 and 6. Repp said that Wells 2 and 6 showed similar types of corrosion, although the metal loss in Well 2 was not as severe as Well 6. Repp explained in detail how damage to the well components occurred due to multiple factors originating w4h-from sand being drawn into the well casing from the surrounding soils. Mayor Lewis asked how long the well assembly had been operational. Utilities Engineer Repp answered approximately 5 years. Utilities Engineer Repp discussed the underlying issues that. staff believes is causing the problems in the wells, well hydraulics, sand production; and well capacity. Repp stated that as the wells are producing water sand is starting to get stirred. up in the aquifer and is getting into the pumps. Director powdy spoke about the importance of Well 2 and 6 and their relationship to Well 7. Water is needed from either Well 2 or 6 to be blended with the water from Well 7. N Repp discussed the well casing and pump design following questions asked by Chairman Vl/agner. Mayor Lewis asked ifithe well casing is damaged. Repp explained that the pump casing within the well casing was damaged but the surrounding well casing was not. Repp showed the Committee photos of the pump and the pump casing attached to the pump. Chairman Wagner asked if there were other materials that could be used in the construction of the pump and casing to prevent the corrosion. Repp answered that the issue is not with the Page 7 Public Works Committee Minutes Februarv 7, 2011 MINUTE$ type of material utilized but there is more of a problem with the sand production and the hydraulics of the pump itself. In a normally operating well, these issues would not occur. Assistant Director/City Engineer Selle explained that the problems with the wells are caused by ~ . a combination of the waythe water is being pumped, what is happening in the aquifer, and how hard the well is being used. Utilities Engineer Repp went over the next steps in correcting the problems with the wells: ' Repp stated that the wells are both high production wells and are close in proximity which may haVe an influence, over #ime, on the wells producing sand. Repp said that staff is currently examining options for the wells, taking into account that resiliency and operational flexibility needs to be incorporated. These options include a well field concept using more wells with smaller capacities and more separation between wells to prevent influence of one well on others nearby and use of variable speed drives. Utilities Engineer Repp and Water Utility Engineer Lamothe answered questions asked by Chairman Wagner regarding the size of the current well field and the water rights boundary. , Assistant Director/City Engineer Selle and Director powdy responded to questions asked by Vice-Chair Peloza about why Wells 2 and 6 were placed in such close proximity of one another.. The Committee and staff discussed possible locations for the wells. Assistant Director/City Engineer Selle-pointed out that there will need to be further study and investigation on the subject: Mayor Lewis asked if we are currently able to use Well 7 since Wells 2& 6 are out of, operation? Director powdy answered that Well 7 is operational and there is a temporary pump running Well 6 that is being utilized to blend with water from Well 7. Utilities Engineer Repp concluded that the initial analysis and design report supported the currenf configuration ofi Wells 2& 6 but over time it appears aquifer conditions may have changed contributing to more sand moving into the wells. Repp discussed using the increased capability of the new SCADA system to monitor and self diagnose key operating parameters at the well sites and using SCADA to also monitor and record useful preventive maintenance data such as, vibration, heat, and well drawdown at varying pump levels. Utilities Engineer Repp answered questions asked by Chairman Wagner regarding the use of monitoring wells. Assistant Director/City Engineer Selle reviewed the next steps staff will be taking in their investigation of the wells. G. WATER CONSERVATION • Water Utility Engineer Lamothe distributed a summary of the current water conservation program.

Between 2000 and 2007 the City saw a significant drop in their per connection demand, not the overall demand because the customer base continued to grow: T'here were increases in commercial, school, and irrigation use and decreases in single- . family, multi-family, manufacturing, and Gity accounts.: With the current program that runs from 2009-2014 the City's targeted a 16/o reduction per year per connection in water use as a goal. ~ Mayor Lewis spoke about the need for conservation and how that affects City revenue. `Water Utility Engineer Lamothe reviewed the measures the City currently implemented to meet the Water Use Efficiency Rule for both demand and supply. The measures the City uses to encourage customers to use water wisely include defined rates for cusfomer classes, tiered customer pricing, utilitybills showing consumption history, school outreach and educational programs, use of the City we6site to promote conservation, the low flow shower and faucet aerators programs; and the WaterSense toilet rebate program. The toilet rebate program was launched in November 2010 and three applications have been processed. Chairman Wagner asked what the toilet rebate amount is: Lamothe answered that the rebate is $100 per toilet with a maximum of two toilets per customer account. Water Utility Engineer Lamothe sfated that the programs implemented by the City are very much inline with what other municipalities and other agencies are doing in the area. Some of the supply side measures are mandated by the Department of Health and they include testing of source meters and replacement if needed, repair and replacement of service meters, control of water loss and annual Jeak detection. Lamothe described some of the lost water that the. City has to.account for,. such as water used for firefighting and flushing the lines. Lamothe reported that staff completes 75 miles per year of leak detection. Vice-Chair Peloza asked who is responsible for testing fire. hydrants.
