ITEM 1: CALL TO ORDER Chairman Barnhouse called the meeting to order at 7:05 p.m. ITEM 2: INVOCATION Mr Jim McElrath, Support Services Director, offered the invocation. ITEM 3: FLAG SALUTE Councilor Michael Helm led in the flag salute. ITEM 4: ROLL CALL PRESENT Mary Lou Barnhouse, Chair Michael Helm, Trustee Denise Bode, Trustee Mark Wilken, Trustee STAFF Rodney J Ray, City Manager Ronald D Cates, Authority Attorney Marcia Boutwell, Authority Secretary ABSENT Tracy Standridge, Vice Chair ITEM 5: CONSIDERATION AND APPROPRIATE ACTION RELATING TO A REQUEST FOR APPROVAL OF THE CONSENT AGENDA. A. Approval of the Minutes of April 7, 1998 Regular Meeting. B. Approval of Claims Dr Bode moved, seconded by Mr Wilken, to approve the consent agenda. The consent agenda included minutes of the April 7, 1998 regular meeting, by reference made a part hereto. Item B on the consent agenda included the following claims: (1) OPWA Fund $21,875.79; (2) OPWA Sales Tax Fund $48,394.40; (3) Payroll $27,083.97. AYE: Bode, Wilken, Helm, Barnhouse NAY: None Motion carried 4 -0. Owasso Public Works Authority April 21, 1998 ITEM 6: CONSIDERATION AND APPROPRIATE ACTION RELATING TO THE AWARD OF A CONTRACT FOR THE BULK PURCHASE OF LOW DENSITY POLYETHYLENE YARD /LAWN WASTE BAGS Mr Roberts said that the City of Owasso began selling plastic yardwaste bags to citizens in the Spring of 1992. The bags are made of a low density polyethylene and are used exclusively for yardwaste disposal. Projections indicate that approximately 20,000 yardwaste bags will be used during the 1998 collection season, and there are currently 10,000 bags on hand. Two vendors responded to a request for sealed bids for bags, and the apparent low bidder is XPEDX of Tulsa. Since the City has had no previous experience with XPEDX, a sample bag was requested. Although the bag is not clear, the contents can be seen and staff believes it meets specifications. Mr Helm moved, seconded by Dr Bode, to approve the purchase of 20,000 yard /lawn waste bags from XPEDX of Tulsa, OK in the amount of $1854, and authorization for payment. AYE: Helm, Bode, Wilken, Barnhouse NAY: None Motion carried 4 -0. ITEM 7: CONSIDERATION AND APPROPRIATE ACTION RELATING TO OPWA RESOLUTION 98 -04, A RESOLUTION ESTABLISHING FEES FOR THE CONNECTION OF ANY WATER OR WASTEWATER SERVICE LINE OR MAIN LINE TO THE CITY'S WATER DISTRIBUTION OR WASTEWATER COLLECTION SYSTEM. I Mr Carr presented the item. The water connection fee represents the cost of installation of a ' new water meter, with associated costs for inspection of the installation and some administrative costs. Fees currently in place have not been revised or updated since being adopted in 1986. The wastewater connection fee is an arbitrary amount established to recapture some of the costs ' of constructing excess capacity in the collection system and treatment plant to handle future users. Resolution #98 -04 establishes fees for connection to the water distribution system and the wastewater collection system. Mr Wilken moved, seconded by Mr Helm, to adopt OPWA ' Resolution #98 -04, increasing the connection fee for wastewater service lines from $375 to $400 and increasing the connection fee for water service from $350 to $400. AYE: Wilken, Helm, Bode, Barnhouse NAY: None Motion carried 4 -0. Owasso Public Works Authority April 21, 1998 ITEM 8: CONSIDERATION AND APPROPRIATE ACTION RELATING TO THE AWARD OF A CONTRACT FOR WATER SERVICE INSTALLATIONS AND PAYMENT FOR WORK PERFORMED UNDER SUCH CONTRACT. Mr Carr said that because of increasing development in the Owasso area, field crews in the Public Works Department Water Distribution Division have been spending considerable time installing new water meters, while needed preventive maintenance for the rest of the system has not been done. Bids have been solicited from private companies to privatize meter installations, including the performance of all work required and the provision of all materials except for the meter. Five vendors submitted bids, with Cunningham Plumbing Co Inc of Tulsa the apparent low bidder. They have been performing similar installations in the City of Tulsa for 15 years. Dr Bode moved, seconded by Mr Wilken, to award a contract for the installation of municipally - owned water meters to Cunningham Plumbing Co Inc, Tulsa, OK, and to authorize payments in accordance with the submitted bid schedule. AYE: Bode, Wilken, Helm, Barnhouse NAY: None Motion carried 4 -0. IITEM 9: REPORT FROM OPWA MANAGER Mr Ray reported on the success of the City's privatization programs. ITEM 10: REPORT FROM OPWA ATTORNEY No report. ITEM 11: UNFINISHED BUSINESS None. ITEM 12: NEW BUSINESS None. Owasso Public Works Authority ITEM 13: ADJOURNMENT Dr Bode moved, seconded by Mr Helm, to adjourn.

ROBERT CARR, JR., P.E. PUBLIC WORKS DIRECTOR SUBJECT: ELM CREEK INTERCEPTOR AUTHORIZATION TO BID DATE: April 29, 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. ELM CREEK INTERCEPTOR APRIL 29, 1998 PAGE 2 Flows from the east side of Highway 169 are pumped to the plant through a lift station located at 117th E. Avenue near 71st 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 Highway 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 along Elm Creek will relieve the Brentwood station and in doing so will relieve the overloadiniz. 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 s sy tem. 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 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 ELM CREEK INTERCEPTOR APRIL 29, 1998 PAGE 3 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 is 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 & Associates. 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, the interceptor has a total probable construction cost of approximately $1,587,382. 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 North 145th E. Avenue. Engineering for the project is estimated to be $75,000 and a right -of -way acquisition allowance of $50,000 has been included. Total probable project cost is estimated to be $1,712,382. 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 ELM CREEK INTERCEPTOR APRIL 29, 1998 PAGE 4 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 $1,242.66 per undeveloped acre (total project cost of $1,712,382 =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 $1,130,324 (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 $459,039 (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 $123,023 (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 4 - Phasing of Improvements). Future planning for additional capacity will need to be 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 ELM CREEK INTERCEPTOR APRIL 29, 1998 PAGE 5 the present [treatment plant] site may not be cost - effective for expansion beyond the proposed planning period [through the year 20151. Future growth will more than likely occur east of Highway 169 in which case a new second plant in that area may yrove 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. INTERCEPTOR DESIGN DOCUMENTATIONS: Crafton, Tull & Associates have developed design documents and specifications for the interceptor. Public Works Department Engineering Division staff have reviewed the documents. The final plans have been approved by Engineering. Bid documents and the advertisement are ready to be published. PROJECT SCHEDULE: The proposed schedule for the project is as follows: Advertisement Pre -bid Conference Bid Opening Award of Bid Notice to Proceed Construction Complete May 7 and 14, 1998 May 27 June 9 June 16 June 24 November 21 (150 calendar days) The developer desires to have the first phase of apartments completed around October 1st. As a result, means to expedite construction will be evaluated. ELM CREEK INTERCEPTOR APRIL 29, 1998 PAGE 6 PROJECT FUNDING: During the March 17, 1998 meeting of the OPWA, the staff reported to the Trustees that there was a "unique window of opportunity" available to partner with the private sector in constructing this interceptor (see attached memo dated March 13, 1998). The concept forwarded was one that allows the entire interceptor to be constructed (rather than utilizing costly temporary solutions) with city- backed financing supported by a private sector "pay- back" as property develops. The Trustees directed the staff to further develop the financing concept, as well as the construction plans for the project. As stated above, the plans and specifications have been completed and the project is ready for bid. Additionally, the staff has explored three options as viable approaches to financing the project using the "pay- back" concept. Those options are 1) a self - funding (revenue anticipation note to the OPWA from the City of Owasso) method; 2) use of a local financial institution (direct loan to the OPWA); and 3) a revenue bond issued by the OPWA. An analysis of those options is currently in progress, with a recommendation expected within the next week. RECOMMENDATION: Staff recommends Trustees authorization to bid construction of the Elm Creek Interceptor. ATTACHMENTS: 1. Memorandum Dated March 13, 1998 2. Resolution No. 98 -01 3.

Design Drawings MEMORANDUM TO: FROM: THE HONORABLE CHAIR & TRUSTEES OWASSO PUBLIC WORKS AUTHORITY RODNEY J RAY CITY MANAGER SUBJECT: REQUEST TO DEVELOP CONCEPT PLAN FOR CONSTRUCTION OF ELM CREEK INTERCEPTOR (WASTEWATER COLLECTION LINE) DATE: BACKGROUND: March 13, 1998 For the past several months, the staff has monitored the increasingly rapid development of the area east of 129th East Ave between 76th St N and 96th St N. 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. ATTACHMENT 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 1 6W 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. REQUEST: 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. RECONVAENDATION: 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.
