ITEM 7: CONSIDERATION AND APPROPRIATE ACTION RELATING TO THE PURCHASE OF A UTILITY TRACTOR. Mr Carr said that the street division budget includes funds for the purchase of a new utility tractor. Bid specifications were prepared and sent to local vendors, and a notice to bidders was advertized on January 29 and February 5. Four bids were received and publicly opened on February 18. The bid submitted by Enlow Ford for a Kubota M540005 is $9.62 higher than the lowest bid; however, the equipment provides greater operator comfort and safety than the lowest bid, and has a delivery time more consistent with department expectations. Mr Ray said that the item was erroneously placed on the OPWA agenda. After conferring with legal counsel, staff believes that it is appropriate for the OPWA to award the bid since the advertisement met all the requirements for trust authority bidding. The payment request will appear on the City Council claims list, therefore allowing that it be paid for from the correct fund. Dr Bode moved, seconded by Mr Wilken, to approve an expenditure in the amount of $15,142.06 to Enlow Ford Tractor Inc, Tulsa, OK for the purchase of one Kubota Model 54005 utility tractor, and authorization for payment.

ROBERT CARR, JR., P.E. PUBLIC WORKS DIRECTOR SUBJECT: AGREEMENT FOR ENGINEERING DESIGN SERVICES - NORTH OWASSO WASTEWATER COLLECTION SYSTEM IMPROVEMENTS DATE: BACKGROUND: March 11, 1998 The 1997 Wastewater Master Plan, adopted by Resolution No. 98 -01 on January 6, 1998, indicated the need for improvements in the wastewater collection system in the vicinity of the existing 106th Street lift station (106th Street west of Mingo Road). Over the past few years, staff has identified needed infrastructure improvements in this area as a result of residential growth and increased sewage flow in the system, deteriorated and undersized collection lines, and severe infiltration/inflow conditions during wet weather. These needs were evaluated and included in the Master Plan. During the past weeks of extensive wet weather, large volume overflows have occurred near the 106th Street Lift Station from the collection system into the adjacent drainage channel. These overflow conditions have been due largely to inadequate capacity of the lift station and the large amounts of infiltration/inflow from the Hillside, Hale Acres and Steed Additions. Although the Master Plan indicated needed improvement options, selection of the most cost - effective alternative will require site - specific engineering to determine the best corrective actions needed. MASTER PLAN OPTIONS: The 1997 Wastewater Master Plan indicates the following pertaining to the 106th Street Lift Station: The 106th Street lift station currently experiences wet weather flows which exceed the station's pumping capacity. This [situation] has resulted in overflows from the collection system upstream of the station. The additional development that is expected within 5 -years will increase these occurrences of overflow. The situation was addressed by evaluating two Page 2 Agreement for Engineering Design Services alternatives. The first alternative consists of increasing the lift station capacity to handle the increased flows. The second alternative is to relieve the lift station with a gravity line. Although the capital cost of upgrading the station is less than the cost to construct a relief line, the present worth analysis demonstrates that the construction of a gravity line to relieve the 106th Street lift station is economically preferable. The options presented in the Master Plan were developed without having the benefit of detailed field survey data and elevations. As a result, it is possible that construction of a gravity line to relieve the 106th Street lift station could be eliminated once actual ground elevations are established or other site construction- related problems are identified. Detailed design engineering is needed to verify site conditions. ENGINEERING PROPOSALS: Staff requested qualification statements on January 13, 1998 from engineering firms capable of providing engineering design services for the wastewater collection system improvements. A packet of information was advertised and sent to twenty -five (25) area engineering firms. Responses were received from seven (7) firms on January 23, 1998. Statements were ranked according to the total number of evaluation points assigned by the Review Committee (consisting of Robert Carr (Public Works Director), Dwayne Henderson (Capital Projects Manager) and Phil Lutz (Engineering Project Manager). Based upon the initial evaluation, the Review Committee identified CTE Engineers, Inc., Dewberry Design Group, Horizon Engineering and HUB +Garver as "Qualified and Highly Responsive Firms ". These four (4) firms were requested to submit a detailed Scope of Services and their proposed fee for final evaluation by the Review Committee. Each firm submitted their detailed scope of services on February 16; 1998. Each submittal was evaluated and ranked by the Review Committee. HUB +Garver was selected as the top ranked firm for fee negotiations. Fees were to be provided with a breakdown for each alternative (i.e., upgrading the lift station and gravity relief line) since definition of scope would be defined as the project proceeded. For comparison, the fee proposals submitted by each firm are summarized as follows: Engineering Firm Lift Station Gravity Relief CTE Engineers $145,467 No data submitted Dewberry Design Group $82,262 $75,482 Horizon Engineering $78,944 $94,536 HUB +Garver $65,000 $62,500 No budget had been established for the engineering work. Page 3 Agreement for Engineering Design Services ENGINEERING SERVICES AGREEMENT: Staff met with a representative from HUB +Garver on March 4, 1998 to discuss the scope of work and fee proposal. As a result of the meeting, the overall scope of work and fee proposed was not changed. An Agreement was drafted and reviewed by the City Attorney. The attached Agreement for Engineering Design Services has been prepared as a result of the review comments. The Agreement is divided into four (4) work phases as follows: Preliminary Design $26,500 Final Design 22,000 Bidding 3,500 Construction Administration 13,000 Total Lump Sum $65,000 PROJECT SCHEDULE: The project design is scheduled to complete design in July 1998. Construction should be able to start in early Fall 1998. A fast -track response time is included in order to expedite the project to correct overflow conditions. FUNDING SOURCE: In 1992, the Owasso Public Works Authority secured a low interest loan from the Oklahoma Water Resources Board (OWRB) for improvements to the water distribution system, wastewater collection system and wastewater treatment plant. Projects involving upgrading the water distribution and wastewater collection systems in the older portion of the city and expansion of the wastewater treatment plant have already been completed or are in progress. The FY97 -98 Budget includes $600,000 as part of the proposed expenditures in the OPWA Capital Improvements Fund for wastewater collection system 'rehabilitation. These funds are a portion of the OWRB loan funds and were allocated to improvements to the wastewater collection system in this north Owasso area. IRECOMMENDATION: Staff recommends the Trustees authorization of an Agreement for Engineering Design Services with ' HUB+Garver Engineers for North Owasso Wastewater Collection System Improvements in the lump sum amount of $65,000.

Recent land purchases and residential development in that area have, predictably, resulted in development plans that are even greater than originally thought (and a more rapid rate of development). A factor influencing growth in that area is the ability/capability to provide wastewater collection and treatment facilities in order to create an economically feasible development. The City has recently adopted a wastewater master plan that addresses the needs and projections for the development of the area east of 129th East Ave (specifically) as a part of the entire system. Generally, the plan notes the need for an interceptor line (a major collector line that serves to collect wastewater from a large area) to be constructed to collect wastewater from a significant area east of 129th East Ave and north of 76th St N. That interceptor is planned to "gravity flow" to the 117th St lift station where the flow would be "pumped" to the city's treatment plant. Eventually, the city's facility plan and master plan call for the construction of a second treatment plant at the 117th St lift station site. Based on the known development plans for the area, the staff believes the city has a unique window of opportunity to partner with the private sector. The concept is for the construction of the base portion of the proposed gravity flow interceptor line, thus avoiding costly temporary lift stations and "forced mains." While the temporary solutions that would be allowed under the city's development plans will allow development, they will have to eventually be removed and the interceptor constructed. The problem with the immediate construction of the interceptor by the private sector is that it is not economically feasible for one developer to undertake. Additionally, it is difficult for developers to jointly undertake such a project because those separate projects do not generally take place in the same time frame. ELM CREEK INTERCEPTOR MARCH 13, 1998 PAGE 2 There is, however, an opportunity for the city government to play a role in the project by providing financing to the project under a "payback" concept. While the base portion of the project is larger than a single developer can justify, the city could use its borrowing powers to complete that portion of the project and require developers to tie into the system and "payback" the city its proportional share of the cost of the design, construction and financing of the project. This concept is widely utilized in most growth cities as a means to develop large areas by sharing the cost of infrastructure. In 1982, the City of Owasso (OPWA) determined that the western and northern areas of the city needed a development incentive (as well as an improvement to some existing facilities) and constructed the "Ranch Creek Interceptor." The entire project cost was born by the city using borrowed funds. While the project did accomplish an immediate goal of improving the collection system (and allowing for the shutdown of several costly lift stations), its success as an incentive for development was not as hoped. Eventually, the interceptor proved beneficial ' as a relief for the rest of the system, but only now are we realizing the originally planned benefits for growth. The proposed Elm Creek Interceptor, however, differs conceptually from that previous project ' in that development plans (Owasso Golf and Athletic Club, KMO Commercial Development, Silver Creek residential and two unnamed office -type developments) are currently being ' processed by the city. Additionally, the use of a "payback" concept should result in the city having only to pick up about $132,000 of the estimated 1.8 million dollar project (due only to the fact that some of the property in the collection area may not develop in the foreseeable ' future. REOUEST: The request is for authorization for the staff to develop a plan for the design, construction and funding of a 1.8 million dollar wastewater project based on the above - described "payback" concept. If the request is approved, the staff will further develop the concept and present options to the Trustees as soon as possible. NOTE: Approval of this request does not authorize the project or expenditure of any funds without future Trustee approval. RECOMMENDATION: The staff recommends Trustee approval of a request to authorize the City Manager to develop a plan for presentation to the OPWA that relates to the use of a "payback" concept in the design, construction and funding of the Elm Creek Interceptor project.

Memorandum from Robert Carr 2. Maps showing proposed project and areas subject to payback provisions MEMORANDUM TO: RODNEY J. RAY CITY MANAGER FROM: F. ROBERT CARR, JR., P.E. PUBLIC WORKS DIRECTOR �Q� SUBJECT: ELM CREEK INTERCEPTOR DATE: March 10, 1998 BACKGROUND: The impact of growth places demands on the infrastructure of the city, specifically on the wastewater collection and treatment system. It is the policy of the Owasso Public Works Authority to be proactive, rather than reactive in matters of growth and development. On January 6, 1998, Owasso Public Works Authority Resolution No. 98 -01 adopted the 1997 Wastewater Master Plan as a policy statement for the extension, expansion and development of privately- financed and publicly- financed improvements of the City of Owasso municipal wastewater collection and treatment system (see Attachment 1). Proper planning and development of infrastructure directly impacts future growth and the 1997 Wastewater Master Plan was prepared to serve as the "road map" for present and future wastewater collection system infrastructure needs. The document incorporates a methodology that combines detailed sewer drainage basins, projected land uses and estimated population densities to calculate wastewater flow in the basin. The flow values were then evaluated to determine collection line and lift station pump sizes, which are computer - modeled to assess existing and future system needs. System needs are detailed in the report based on the present, 5 -, 10- and 20 -year growth projections. It was recognized that implementation of the Wastewater Master Plan has the potential to have significant wide - ranging impacts concerning present and future infrastructure. Costs associated with expansion and extension of the wastewater collection and treatment system can affect development feasibility. SYSTEM GROWTH REQUIREMENTS: As new development occurs in Owasso, wastewater collection system expansion is generally projected to be divided into two (2) major collection zones. These zones are east of Highway 169 and west of Highway 169. Presently, all collected flow is ultimately transported to the Wastewater Treatment Plant. Page 2 Elm Creek Interceptor ' Flows from the east side of Highway 169 are pumped to the plant through a lift station located at 1 17th E. Avenue near 71 st Street North. The Master Plan indicates that a significant portion of the future development that is projected to occur in the next 20 -years will contribute flow to the 117th E. Avenue Lift Station. The growth that is projected on the eastern side of IEghway 169 will require that some improvements are made in order to allow these higher flows to reach the main plant. In addition, the Master Plan provides detail concerning development in the Elm Creek drainage basin as follows: The Elm Creek basin is projected to have a substantial amount of development within the next 20- years. A large portion of this growth will occur in the next 5 -years in the vicinity of the Brentwood lift station [located on 86th Street North east of the Junior High School]. The station itself has adequate ability to serve all of the new development that is projected to the north of 86th Street North and east of the existing development; however, the flows will cause severe overloading in the Elm Creek interceptor downstream of the Brentwood discharge... Ultimately, the construction of a gravity line along Elm Creek will relieve the Brentwood station and in doing so will relieve the overloading. Some development is expected to occur south of the Brentwood lift station within the next 5- years. These areas cannot be served by gravity lines into the Brentwood lift station or into any _part of the existing collection system. Additional development is projected further south (downstream) of the area within 10- years. Further downstream more development is projected within 20- years. Development of this basin from upstream to downstream prevents the natural iterative construction of the East Elm Creek Interceptor. Because of this, intermediate alternatives [were] evaluated to determine the most cost - effective method of providing sewer service to these areas. Proposed development in this area has been occurring as described in the Master Plan. At present, development plans have been submitted that will require wastewater collection for essentially the entire undeveloped area south of 86th Street North between North 129th E. Avenue and North 145 E. Avenue (Albertson's and Owasso Golf and Athletic Club). Other development is likely to occur north and east of 86th Street North and North 145th E. Avenue, as well as with continued development north of 86th Street North west of North 145th E. Avenue (Silvercreek Addition). To accommodate growth as projected, the Master Plan incorporates scenarios that combine expansion of gravity interceptors, interim lift stations and force mains over a 20 -year period. The 5- year development plan (see Attachment 2 - Figure V -15 from the Master Plan) includes extension of the interceptor to the north, flow diversion from the Brentwood lift station and construction of two (2) interim lift stations and force mains. As development continues, the 10 -year development plan Page 3 Elm Creek Interceptor includes elimination of the two lift stations, extension of the interceptor south to 76th Street north and construction of another interim lift station and force main (see Attachment 2 - Figure V -16 from the Master Plan). The 20 -year development plan (see Attachment 2 - Figure V -17 from the Master Plan) shows the elimination of the lift station and continuation of the interceptor south toward the 117th E. Avenue lift station. Ultimately, the Elm Creek basin will be served by a gravity sewer interceptor system. Three (3) interim lift stations and three (3) force mains will be removed or abandoned. PROPOSED ELM CREEK INTERCEPTOR PROJECT: Recent activity involving the undeveloped area south of 86th Street North between North 129th E. Avenue and North 145 E. Avenue (Albertson's and Owasso Golf and Athletic Club) has resulted in discussion concerning a long -term method to provide wastewater collection. Provision of interim lift stations and force mains for this area and their short-term costs have been evaluated. Consulting engineers (Crafton, Tull & Associates, Inc.) for Lindsey Properties (Owasso Golf and Athletic Club) have approached engineering staff to determine feasibility of constructing the interceptor. Constructing the interceptor would eliminate costs of constructing lift stations that are intended to be rather short-lived. The majority of expense of lift station and force main construction would be lost once the interceptor is ultimately constructed. Crafton, Tull has proposed that Lindsey construct the portion of the interceptor from 76th Street North to a point on the south side of the Owasso Golf and Athletic Club property (see Attachment 3). The portion of the interceptor from the 117th E. Avenue lift station to 76th Street North would be constructed by the City of Owasso. Construction of the interceptor in this manner (i.e., from south to north) will enable wastewater collection to be accomplished without the need for interim facilities and enable the system easily to be extended north. PROJECT COSTS: The interceptor would be sized and designed to carry additional flows for the total area to be served ultimately. As a result, costs of construction should be allocated to appropriate undeveloped property in the basin in order to proportionately distribute construction expenses to present and future users of the interceptor. A detailed evaluation of construction costs has been performed by Crafton, Tull. Considerable effort was also expended to identify the extent of rock in along the route of construction in order to prepare a realistic cost estimate. As a result of this work, construction of the interceptor to the south side of the Owasso Golf and Athletic Club property has been estimated as approximately $1,526,250 (see Attachment 4 - Engineer's Cost Estimate). The line will continue through a portion of the Club property at the developer's expense and then extended to the intersection of 86th Street North and Page 4 Elm Creek Interceptor North 145th E. Avenue (approximately 1800 LF) at an estimated cost of $187,500. Engineering for ' the project is estimated to be $75,000 and a right -of -way acquisition allowance of $50,000 has been included. Total estimated project cost is $1,838,750. M Users of the interceptor are expected to contribute to the project costs based upon their contribution to the amount of wastewater generated. Staff believes that this contribution is directly attributed to development acreage. Therefore, the present undeveloped interceptor drainage area has been compiled to determine a per acre charge for the interceptor construction. A total of 1378 undeveloped acres were identified (see Attachment 3). Present and near -term development potential Reimbursement of project costs have been estimated as $1,334.36 per undeveloped acre (total project cost of $1,838,750 =1378 acres). Based on present and near -term development plans, approximately 909.6 acres (areas D, F, H, I, J, K, L, P, and Q) are identified to develop relatively quickly. Reimbursable costs of $1,213,735 (approximately 66% of the total estimated project costs) are associated with these areas. Short-term development potential Another 369.4 acres (areas E, G, M and N) can be expected to develop in the in the next few years. Reimbursable costs of $492,913 (or an additional 27% of the total estimated project costs) area associated with these areas. Long-range development The remaining 99 acres (areas A, B, C and O) are not expected to develop in the immediate future. Associated costs of $132,102 (7% of the total project) would remain uncollected until development occurs. OTHER PUMPING AND TREATMENT CONSIDERATIONS: Flow Equalization at 117th E. Avenue lift station Wastewater flows in the Elm Creek Interceptor to the 117th E. Avenue lift station. As the flows increase, the Master Plan indicates that some improvements will need to be made in order to allow these higher flows to reach the Main Plant. The most cost - effective improvement will be the construction of a flow equalization basin near the lift station to provide storage and constant pumping to the plant. Land will need to be acquired near the lift station to accommodate a total of 10- million gallons of wastewater storage. It is projected that the facility would be constructed in two 5- million gallon phases by year 2002 and 2007. Total present worth capital cost is estimated as approximately $3,600,000. Wastewater Treatment Capability The present Wastewater Treatment facility will have capacity to treat 2.15 million gallons per day (MGD) at the completion of Phase I improvements presently under construction. Phase II improvements will need to be operational in the year 2001 to increase capacity to 3.3 MGD (see Attachment 5 - Phasing of Improvements). Future planning for additional capacity will need to be Page 5 Elm Creek Interceptor initiated in the year 2012. Treated wastewater flows to Owasso Creek, then ultimately to Bird Creek. The discharge effluent quality to the creek is modeled based on Bird Creek water quality criteria. An amendment to the Facility Plan for the Wastewater Treatment Plant (prepared in September 1994) indicates that the present [treatment plant] site may not be cost - effective for expansion beyond the proposed planning period [through the year 2015]. Future growth will more than likely occur east of Highway 169 in which case a new second plant in that area may prove to be more cost - effective than to pump the flow top the present site for treatment. Further expansion of the existing site will require considerable amount of fill and flood protection. Construction of a new facility on the east side of Highway 169 would be expected to be in the vicinity of the 117th E. Avenue lift station, since the station is the terminus of the gravity collection system and the proposed location of flow equalization. Discharge of treated wastewater from the facility would likely be to another location on Bird Creek. Water quality modeling for this discharge would be performed by INCOG. Based on conversations with modeling personnel, it is anticipated that modeling will result in significantly higher treatment requirements for a new facility as well as for the existing plant. Advanced treatment to remove more organics, suspended solids and to include nutrient removal should be expected for both discharges. Construction costs of a new facility and needed retrofitting of the existing plant cannot be accurately determined until the level of treatment is defined. However, the 1.15 MGD expansion for Phase II improvements at the existing facility is projected to be approximately $6.7 million. If construction of a 2 MGD plant is needed on the east side of Highway 169 in year 2015, costs at that time can be expected to exceed $12 million. ATTACHMENTS: 1. Resolution No. 98 -01 2.
