Foster & Associates, Inc. for conducting an assessment of its water systems. It asked for identification of corrective actions and presentation of recommendations in an organized development plan, divided into phases to allow it to plan its workload and arrange for funding. • This Study Report documents results from the third of three tasks under this Water Compliance Study. Task 3 presents recommended actions for capital and operation improvements and other corrective actions. The tasks were executed in this order: • Task 1 —Background Investigation • Task 2—Develop Options • Task 3 —Study Report Anytime a utility as important as a water system is studied and changes proposed, City staff, its Council and management, and members of the public rightfully need to be engaged in the process. We encourage this involvement and participated in two review sessions with the City Council during the conduct of the Water Compliance Study. 1.2 Project Team The project manager of our team is Loren Leman, P.E., a vice president with Michael L. Foster & Associates, Inc. MLFA was supported in Task 3 by subconsultants CH2M HILL for cost estimates for instrumentation and control improvements for wells, tanks and booster station and conversion from chlorine gas to sodium hypochlorite disinfection; and Tauriainen Engineering and Testing for water line cost estimating. The City of Seward's Contracting Officer is W.C. Casey, its Director of Public Works. Seward Water Compliance Study 1 December 30,2008 Task 3 Study Report SEWD-SEWD-001-0001 1.3 Schedule Work on Task 3 started after draft Technical Memorandum No. 2 was submitted to the City on May 12, 2008 and continued after our final report for Task 2 was completed on August 15. The City agreed to additional time to produce the draft Task 3 report to accommodate staff commitments and a review meeting with the City Council originally scheduled for September 8, but rescheduled for September 22 at the City's request. Subsequently the City further extended the time to complete this final report. This final document incorporates comments from the September 22 Council meeting and additional discussions and correspondence with City staff. 1.4 Acknowledgments The City of Seward has a well-deserved reputation for delivering a quality water product, and being responsive to its customers and regulating authorities. Its water utility is fiscally sound. We join others in congratulating the Public Works staff for Seward's recognition on May 7, 2008 by the Alaska Water Wastewater Management Association for operation of its water systems. 1.5 Setting Seward is located at the northern end of Resurrection Bay on the southeast coast of the Kenai Peninsula, 126 highway miles south of Anchorage. It is one of the most spectacular settings in Alaska with historic ties to Alaska's territorial days. Seward lies in the maritime climatic zone, with cooler summers and warmer winters caused by the moderating influence of the nearby Gulf of Alaska. Although major rain and snowmelt events sometimes create localized flooding, they also provide the mechanisms for supplying the City's water resources. The City's water supplies are plentiful, of good quality, and reasonably well protected. However, with its continued development, particularly as a tourist and recreational destination and an industrial and commercial location, Seward faces challenges with protection and delivery of its water. Winter water consumption of 1 million gallons per day (mgd) triples to 3 mgd in peak summer days, driven largely by seafood processing, cruise ships, fishermen and recreationalists, and other visitors. Seward Water Compliance Study 2 December 30,2008 Task 3 Study Report SEWD-SEWD-001-0001 As a protected ice-free harbor, port-of-call for the Alaska Marine Highway System, and southern terminus for the Alaska Railroad and Seward Highway, Seward has long been important in transportation. It is a service port for southcentral Alaska and other parts of our state. Seward's economy has diversified with tourism, recreational and retail opportunities; commercial and z;r3 sport fishing; seafood processing; a shellfish hatchery; University of Alaska Institute of Marine 0,.!.4•4 Science and Alaska SeaLife Center 'marine vesselfisery s e airs and storage a State p so'gi n, ,• „ Z,., rK .Rf is �r r r td+ �': n rYI`"'a e� � ) +!,�'k`^ "w.h a � LY 7 L '- � •� � y,�r; . + � ~��`"➢7$ � i �4 �.:F� v+#w � '-�w�r'� `,it ocational,'t a hitigi center, arc .government e o.e7: -s ,_ 'ces tae l ' p o.' 1 . 9, tc zr, tCt `..6FY r7 •pr"' i tiva�4' ^' a }�twy a n' &.;.;G+ ., •s p a } .r ,N3,%i f�3, 3c�.: 4;1. +:, rf �r r f 5th' _,.Y✓.� �" y y"�r.'�"��„ !t)w,",,L� °n T . i�" �q .•Y-'' i'�-�'� r�w :s r� j�.}�, a ¢aF�l�ro +_u ex eedu�g,3, 00_,isjrelativel-y=stable;f:}fit,cont�riue d{© g _o a ou xde' o �oe s '4 V �~ ", '- s �� ,..�„x„�.�:ia >r=�;..7. �'..c•.r.,. �' Xw''.r'a: •'�'d'. �..�..�''w"..a a..,r.A:f impacts the City and its services. The City's 2020 Comprehensive Plan, its guiding document for development adopted by the City and Kenai Peninsula Borough in 2005, acknowledges Seward's continuing challenge to retain its unique historic, small town character, while pursuing economic development opportunities and accommodating changes. in business services, public facilities, and affordable housing. Continuing to provide good drinking water is part of meeting that challenge. 1.6 Previous Results Our first report, Technical Memorandum No. 1, documents the configuration, operation,.and permit compliance reporting for the two water systems operated by the City: 1) the City system, which serves nearly all of the developed area on the west side of Resurrection Bay; and 2) the Seward Marine Industrial Center (SMIC) system, which serves the Spring Creek Correctional Center, the marine industrial center, and seafood processors in the Fourth of July Creek area on the east side of Resurrection Bay. That report demonstrated that the City operates its water systems in compliance with regulations and produces high quality water under sometimes challenging conditions. We also flagged areas that could be improved, including recordkeeping, investigation of apparent corrosivity, and leakage. In Technical Memorandum No. 2, our second report, we identified specific ways to address these and other water system needs for the City water system. This included water storage, a new booster station, and water distribution replacement and improvements. Recommended electrical and control improvements were presented for seven facilities. Seward Water Compliance Study 3 December 30,2008 Task 3 Study Report SEWD-SEWD-001-0001 2.0 RECOMMENDED PROJECTS This section briefly summarizes recommended projects to improve Seward's water system. These have been discussed in more detail in Technical Memorandum No. 1 and Technical Memorandum No. 2. Table 1 identifies costs associated with these projects and establishes an order of priority. We have assumed that projects costing less than$50,000 will be covered under the City's normal operation and maintenance budget for the water utility. 2.1 Water Source The Fort Raymond aquifer capacity is substantial—much greater than what is currently being produced from it. If needed in the future, the City could install other wells and use Variable Frequency Drive (VFD) technology to match pumping capacity with need. Although improvements are needed at individual wellhouses, we believe well capacity and quality are sufficient for the near future and improvements can be part of routine maintenance. We previously suggested that Seward consider implementing additional protections in its Fort Raymond aquifer recharge area, particularly in what is identified in Technical Memorandum No. 1 as Zone A, the area closest to the wellfield. This will require door-to-door and field surveys; public involvement programs, including workshops and hearings; and other assistance with adopting a watershed protection ordinance (see Technical Memorandum No. 2 for a suggested draft ordinance). Additionally, seven wells no longer in use nor needed should be properly abandoned to reduce the risk of contaminating the City water supply. 2.2 Water Treatment Although the City is not anxious to change its disinfection method, it wants to be prepared in case this is ever required. If chlorine gas ceases to be a viable option because of public concern, regulatory agency mandate, security, or rising costs, the best option for the City is on-site chlorine generation from salt, water and electricity. This would relieve the City of safety concerns associated with gaseous chlorine handling and use, and might result in a cost savings over a 20-year investment period. 4 December 30,2008 Seward Water Compliance Study SEWD-S December 2008 Task 3 Study Report Although the handling of liquid sodium hypochlorite generated onsite will be safe, certainly as compared to chlorine gas, it will also be less convenient. Unless wells in the Fort Raymond area are interconnected by piping to distribute the disinfectant, the liquid sodium hypochlorite will need to be trucked weekly from a central generation site (presumably Wellhouse No. 6) to storage tanks in each of the other wellhouses, including the distant facility that serves the Seward Marine Industrial Center (SMIC) system. Operator and vehicle time for this activity will need to be planned and budgeted. 2.3 Water Distribution By adding Well No. 6 to the City's inventory in 2000, water distribution to the northern end of Seward has improved considerably. However, because this well is now operated as the City's primary water source, restrictions in the lines (likely both size and condition) between Well No. 6 and peak water draw-off locations (for example, the Port area) cause substantial headloss and limit water distribution. This shortcoming was again demonstrated during summer 2008. Distribution would be improved if a new 12-inch diameter line were constructed from Hemlock Avenue near Well No. 6 to connect with the rest of the wellfield and water distribution system immediately to the south. In addition, the age and condition of pipe materials suggest that an ongoing, systematic waterline replacement program would be prudent. The highest priority segments should be the oldest asbestos cement and cast iron lines that might have hydraulic limitations and be sources of leakage. Continuation of improvement of the distribution "spine" from Phoenix Road to Sea Lion Avenue should become a priority. Additionally, extensions of water mains may be necessary to provide service to areas within the City not yet developed—but scheduled for development according to the 2020 Comprehensive Plan. A previous report for the City, now eight years old, suggested options for increasing pressures in the.Port area during simultaneous fire and cruise ship demands. The existing 6-inch and 8-inch diameter water mains leading into the Port area could be increased to at least 10-inch diameter. Alternatively, a new 10-inch diameter pipe loop from the Port area through the airport area and back west across the highway to the existing 10-inch water main could be constructed. In our opinion, a more practical, less expensive, and safer option would be to interrupt the cruise ship Seward Water Compliance Study 5 December 30,2008 Task 3 Study Report SEWD-SEWD-001-0001 filling while fighting a Port area fire. Subsequently, we have listed this project as a lower priority on Table 1. The booster station near the intersection of Benson Drive with Swetmann Avenue lifts the water from the Town Zone to higher elevations in the Gateway Zone. Although it has served the City well, this station is nearly 30 years old and is approaching the end of its useful life. It is space- limited and has Code issues. The City has made temporary structural repairs that allow this station to continue to operate, but operation and maintenance conditions are not ideal. We recommend its replacement become a City priority. 2.4 Water Storage Seward's City system has three water storage tanks with a combined volume of 1.1 million gallons, about the same as the community's daily use during the off-peak season. However, during peak summer use, it has only eight hours of available storage. A fourth tank, supported as a proposal in the 2000 study, would be a big help. An additional benefit to this improvement would be the ability to use the new storage tank to increase chlorine contact time before the water is distributed to customers. The City and CRW, another engineering firm, have been working on design of a new 500,000- gallon water storage tank originally proposed to be located near the high school, and operated at the same water surface elevation as the Lowell Canyon tanks. Although its final location has not been decided, we continue to believe a site near the high school is best. Resolution of site control with the Kenai Peninsula Borough is needed. This is a high priority project. 2.5 Instrumentation & Control Our review of instrumentation and control for the wells, booster station and water storage tanks included field observations and operating staff interviews. Although much of the City's electrical and control systems is "old technology," some is reliable and proven. However, it is getting harder and harder to find replacement parts. Newer controls will reduce labor costs and make the system operate more efficiently. We recommend this project as one of the City's highest priorities. Seward Water Compliance Study 6 December 30,2008 Task 3 Study Report SEWD-SEWD-001-0001 3.0 COST ESTIMATING Estimates of costs are based on City experience, comparable municipal projects, recent bid tabs, quotations from material and equipment suppliers, and our own engineering and construction experience. All costs are presented in 2008 dollars and will need to be adjusted to account for construction cost increases, labor contracts, inflation, fuel and other factors that affect prices in this dynamic marketplace. 3.1 Capital Cost Methodology For water lines, we used $200/ft in low conflict areas and $250/ft in areas of greater conflict, and areas with the potential for more traffic interruptions, for example, along the Seward Highway. These unit costs include ancillary facilities like hydrants, valves, special borings and encasements. The recent Third Avenue water main upgrade project was completed in 2006 for $330 per foot. However, it had substantial costs associated with traffic and utility conflicts—as well as traversing an area with substantial water. We used$300 per square foot for buildings. In addition, we provided for a total allowance of 60 percent to cover engineering design and services during construction (20 percent); administration, legal and finance charges (15 percent); and contingencies (25 percent). These are commonly used allowances at this stage of project planning. Engineering design and services during construction will depend on the scope of services, complexity and size of the projects, and how the City may decide to administer them. Depending on how it structures its financing, the City will incur expenses related to acquiring and servicing debt. The allowance for this includes costs for accounting, legal services, interest, and debt. An allowance for contingencies covers unknowns such as bidding timing and climate, geotechnical and groundwater conditions, contamination and other environmental challenges, utility and transportation conflicts, delays, and other incidental costs. The costs presented in this Study Report need to be adjusted during design, as more of the detail about routing, connections, conflicts, needs for right-of-way, methods of construction,roadway disruption and replacement, and marketplace dynamics become known. Seward Water Compliance Study 7 December 30,2008 Task 3 Study Report SEWD-SEWD-001-0001 • 3.2 Operation and Maintenance The utility fund for operating and maintaining the City's water systems is healthy. Because of foresight and good management Seward is in an enviable position of having cash reserves in this fund to enable it to provide for its ongoing needs and plan for its future, without it being totally dependent on others. Typically new construction comes with two price tags—the initial capital outlay and ongoing costs to operate and maintain the facilities. This is no different for Seward. However, several of the recommended projects will actually reduce operating costs (for example, improvements to instrumentation & control) and some may increase utility revenues (for example, improvements to improve water delivery to cruise ships and other customers that reside outside City limits). An ongoing and systematic replacement of aging pipes will reduce leakage and maintenance needs. On the other hand, a new 500,000-gallon water storage tank will require increased maintenance attention. We have evaluated the priority projects presented in Table 1 and conclude that the need for increased operator attention for some projects will be offset by savings for others. These capital improvement projects should not result in net operational cost increases. However, the City of Seward should continue to monitor its staff workload and associated costs, reserve requirements of lenders, and its ability to meet customer and regulatory needs as it develops its budgets and sets the rates it charges its customers. Seward Water Compliance Study 8 December 30,2008 Task 3 Study Report SEWD-SEWD-001-0001 4.0 POTENTIAL FUNDING SOURCES The City of Seward is well managed—and because of foresight has not only been able to pay its bills, debt obligations and taxes, but has also established a reserve for utility emergencies and capital improvements. These funds are not, however, unlimited and the City will need to supplement its own funds with grants and loans if it is to implement the recommended projects in the near term. Funding for individual water improvement projects will likely be varied, and probably will be from a combination of sources. Many of the granting and loaning agencies like to see broad and substantial participation in projects. Potential funding sources include: 4.1 Seward Water Utility Funds The City's cash reserves are the easiest funds to access. Authorization and appropriation will need to be by the City Council. The City currently has more than$1 million in reserve for capital improvements to its water system. We have assumed these funds will be used for smaller projects that become priorities and need to be done quickly, and for matching funds to support financing for the larger projects. 4.2 Alaska Municipal Matching Grants This program administered by the Department of Environmental Conservation (DEC)provides partial funding for drinking water and other projects,primarily for boroughs and the larger communities in Alaska. State grants come from General Fund appropriations often supported by , federal funds from the Environmental Protection Agency(EPA) and the U.S. Department of Agriculture(USDA). If projects cost more than $3 million, the program usually requires phasing. Although the application period for FY10 closed on August 4, Seward maybe able to submit a supplemental request, or be prepared for applying for FY11 funding.

Getting on the priority list for these loan funds is not difficult—however, getting on the fundable portion of the list is. Seward has tried in the past, and has not received funds, so will need to make changes to its loan applications to improve its chances. We expect that if qualified communities continue to have difficulty getting loan funds, the Legislature will increase the capital in this fund so the State can loan more money. This is especially important in today's fiscal climate.

However, in recent years, even though the Legislature has increased funding for capital projects, it has relied heavily on priority lists, such as those developed by the DEC, to fund needs around the State. Governor Sarah Palin also considers demonstrated need when she reviews and acts on the annual capital budget. Seward is host to a major State institution, the Spring Creek Correctional Center. The State of Alaska is considering expansion of this facility and likely will support its project by investing in needed utility improvements and expansion. It may also recognize that its workforce impacts other parts of the Seward community through making additional investment in water and other local projects. We suggest that the City of Seward present its needs to its Representative and Senator and request assistance for getting funds either through a DEC-administered grant or loan, or by a separate direct appropriation.

It was created to address disadvantages Alaska's communities often experience in financial markets. By grouping needs of Alaska's communities into common bond sales by the State of Alaska, the Bond Bank is able to attract funds at competitive rates, which it uses to loan to Alaska communities. The AMBBA has an A rating from both Moody's and Standard and Poor, which enables it to borrow at low rates. This bank is self-supporting, has never defaulted on its bond payments, and even returns funds to the State's General Fund annually. The City of Seward is familiar with AMBBA as it has used this mechanism for funding its electric utility improvements. For planning purposes, the City can assume that loan funds are available at 4.5 percent for 20 years from this source. However, the bond market is very dynamic and the City should update this information with AMBBA if it decides to pursue funding through this vehicle.

Grants may be made for up to 75 percent of eligible project costs in some cases. Some of these funds might be available to the City of Seward, even if the City's projects are not funded through the DEC priority list. It may not hurt to ask.
