The existing collection system consists of over 100 miles of sanitary sewer line (ranging in size from 4 to 21 inches in diameter), 12 pump stations and a 3.3 million gallon per day (MGD) treatment facility. In response to rapid growth, in 2005 the City of Owasso commissioned the update of its 1997 Wastewater Master Plan. The update, now completed, provides a 20 -year guide for the prioritization and construction of upgrades to the City's conveyance and treatment infrastructure. Among the immediate needs, the plan recommends the investment of approximately $7 million for the upgrade of the Wastewater Treatment Plant and the 117th Street Pump Station. The recommended improvements will increase the average treatment plant capacity to 4.5 mgd — which is anticipated to meet treatment demand for the next 10 years. Similarly, improvement to the 117th Street Pump Station will upgrade existing facilities thereby increasing pumping capacity to accommodate present and future needs. In order to meet these needs, the City of Owasso invited Statements of Qualifications for Professional Engineering Services from three consulting firms to provide design services for these improvements. Following an evaluation and recommendation by both engineering and operations staff, the Authority awarded a contract for engineering services to Greeley & Hansen in the amount of $545,000 during it's regularly scheduled meeting of July 13, 2007. Design work under this agreement is on -going and on schedule. ADDITIONAL PROJECT SCOPE: Extensive current and proposed development in the southwestern corner of Rogers County, east of Owasso, has created an opportunity for the extension of City of Owasso sanitary sewer to this area. In September 2007, City of Owasso engineering and operations staff began discussions with Greeley & Hansen concerning the development of a design for a sanitary sewer interceptor Amendment to the Agreement for Engineering Services Sanitary Sewer Treatment and Collection Improvements Page 2 of 3 along the E. 76th Street North alignment to serve an area generally bounded by E. 76th Street North to the north, Verdigris River to the east, E. 59th Street to the south, and N. 143rd East Avenue to the west. This area consists of all or portions of Sections 25, 26, 35 and 36 of Township 21 North, Range 14 East, Sections 1 and 2 of Township 20 North, Range 14 East and Section 31 of Township 21 North, Range 15 East. In all, some 4,708 Gross Acres are drained by the service area and 3,136 Net Acres are available for development. The estimated build -out population of the service area is 8,727. The proposed 76th Street Interceptor would be a gravity sewer and would extend east from the Elm Creek Interceptor (west of the 76th Street North/145th East Avenue intersection) to approximately 177th East Avenue, a distance of 2.2 miles. The western 8,200 lineal feet of the interceptor is proposed to be constructed of 18" PVC pipe; the eastern 3,500 lineal feet of the interceptor (76th Street North Interceptor – East Extension) is proposed to be constructed of 10" PVC pipe. Planning -level construction cost for these two components is estimated to be $3,100,000. Early in November, Greeley & Hansen furnished for staff review a memorandum providing a preliminary evaluation of estimated wastewater flows and sewer infrastructure necessary to serve the proposed basin. This memorandum is provided as Attachment A AMENDMENT TO THE ENGINEERING SERVICES AGREEMENT: Based on the memoranda of additional project needs and scope for the 76th Street Interceptor Sewer, City staff requested from Greeley & Hansen an amendment to the previously approved Engineering Services Agreement. Engineering Services to be performed by the engineer under this amendment include: — Preparation of a preliminary engineering report (PER) to qualify the proposed project for ODEQ State Revolving Fund financing. — Preparation of preliminary and final design for approximately 11,700 lineal feet of gravity sewer (including design survey, mapping and geotechnical investigation). — Preparation of contract documents including drawings, specifications and permit applications for the project. — Bid related assistance. Greeley and Hansen has developed staff -hour projections for the additional scope and submitted a fee proposal in the amount of $189,000.00 (Attachment B). PROJECT SCHEDULE: The design of the 76th Street Interceptor will be performed concurrently with the design of the Wastewater Treatment Plant Expansion and Pump Station Upgrade. It is anticipated that design for the project will require approximately six months to complete. The schedule below illustrates Amendment to the Agreement for Engineering Services Sanitary Sewer Treatment and Collection Improvements Page 3 of 3 a proposed start date of January 2, 2008 and an approximate completion date of July 3, 2008 (for engineering services). — Notice to Proceed to Greeley & Hansen from the City of Owasso – December 19, 2007. — Project Start Date – January 2, 2008. — Complete Design Survey and Geotechnical Investigation – February 15, 2008. — Complete Preliminary Design/Utility Coordination – April 25, 2008. — Complete Final Design – May 23, 2008. — Complete DPW /ODEQ Review –June 27, 2008. — Advertise for Bids – July 3, 2008. — Receive Bids – August 5, 2008. — Council Approval/Notice to Proceed – September 9, 2008 — Construction Complete – July 6, 2009 FUNDING: Funding for this project will be obtained from the Oklahoma Water Resources Board (OWRB) via a loan from the Drinking Water State Revolving Fund. Resolution No. 2007 -06, passed by the Authority during its meeting of July 13, 2007 declares the Authority's intent to be reimbursed from proceeds of the OW" loan for project expenses incurred by the OPWA prior to loan closing. FY 2007 -2008 allocation for Wastewater Improvements provides sufficient temporary funding pending reimbursement from OW". RECOMMENDATION: Staff recommends OPWA Trustee approval of an amendment to the Agreement for Engineering Services for the Wastewater Treatment Plant Expansion and 117th Street Pump Station Upgrade with Greeley and Hansen, LLC (Chicago, Illinois) for the purpose of expanding the scope of services to include the design of the 76th Street Interceptor Sewer project in the amount of $189,000 and authorization of the Chairman to execute the document.

Service Area Map GREELEYAND HAIVSEM MEMO Date: November 6, 2007 To: Roger Stevens and Joe Nurre From: Joe Teusch Subject: Proposed 76th Street Interceptor General The following is a preliminary evaluation of estimated wastewater flows and sewer infrastructure needed to serve the proposed Stone Canyon development and surrounding areas. Figure 1 shows the proposed sewer service area which is generally bordered by 765` Street to the north, the Verdigris River to the east, 59t" Street to the south and 143`d Street to the west. It is anticipated that sewer flows from this area will be conveyed to the Elm Creek Interceptor located one -half mile west of the 76th Street and 143`d Street intersection. Estimated Wastewater Flows Table 1 shows the estimated average and peak flows for the service area to be 1.10 mgd and 2.75 mgd, respectively. Estimated average and peak flows, tributary to specific sewer reaches, are shown in the table below.

A lift station (by others) is proposed approximately one -half mile north of the 66'h Street and 161s1 Street intersection at the junction of the north and south branch sewers (by others). The lift station would pump flow approximately one -half mile north to the 7611h Street and 1615 Street intersection. A new interceptor (by City) is proposed to convey the flow approximately 1.5 miles west, from the 76`h Street and 1615' intersection, to the existing Elm Creek Interceptor. Extending the interceptor to the east would help to spur development north of 76'" Street and would allow future service to the residential areas currently on septic systems. The table below summarizes the preliminary bases of design for the proposed sewers and lift station.

ALEXANDER PROJECT MANAGER SUBJECT: WATER SYSTEM IMPROVEMENTS PHASE II WEST TRANSMISSION MAIN, BOOSTER PUMP STATION AND PRESSURE PLANE APPURTENANCES; CHANGE ORDER NUMBER 2 AND ACCEPTANCE OF PROJECT DATE: December 13, 2007 BACKGROUND: Included as part of the improvements recommended by the Water Master Plan, this project represents the last phase of enhancements to the City's water distribution system to address water demands for the next twenty years. Specifically, the improvements include approximately two miles of 30 -inch water transmission piping along East 106th Street North, a new booster pump station (located in the base of the recently completed 2 million gallon water tower) to maintain transmission pressure during periods of peak demand and pressure regulating appurtenances to allow the separation of pressure planes. Bids for the project were received on January 9, 2006. McGuire Bros. Construction Company was determined to be the lowest responsive and responsible bidder and the Public Works Authority awarded the construction contract in the amount of $3,848,184.63 to them during its regular meeting of January 17, 2006. On March 20, 2007 Council approved Change Order No. 1 in the amount of $170,389.73 to bring the overall contract amount to $4,018,574.36. CONTRACT CHANGES: The work was awarded as a unit price contract where the quantities presented in the Bid Form were estimated based on expected conditions and used solely for the purpose of comparing bids. It was therefore anticipated that a quantity adjustment would be made at final payment to reflect actual quantities provided, as well as any changes in the scope which may have developed during construction. Funding for final quantity adjustments, and other necessary changes, was included under the Project Allowance Line Item ($210,000) listed in the Bid Tabulation and Project Schedule of Values. Acceptance of Project Change Order No. 2 Water System Improvements Phase H Page 2 of 17 The Summary of Project Over -runs and Under -runs (Attachment A) indicates each item that varied from 100% completion. Many of these costs are associated with small amounts of an item either unused or used in addition to the estimated quantity. This report indicates $194,442.78 in quantity under -runs and $383,671.50 in quantity over -runs; of which $183,600.00 is accounted for by the single item relating to extended temporary pump station use. The net cost of contract quantity over -runs is $189,228.72. The Project Allowance Summary (Attachment B) summarizes items not anticipated in the original scope but required for the proper completion of the project. These items included an additional pressure regulating structure between the 30" transmission line and the 12" distribution line, conduit and telemetry circuits to allow for remote monitoring of the status of the new Tulsa master meter vault, valves and fittings to increase the efficiency of the temporary pumping facility, and other miscellaneous fittings, services and items. Total charges against the Project Allowance, as additions in the scope of this project, total $135,998.06. This amount is included as Item 63 on the "Summary of Project Over -runs and Under -runs (Attachment A). It also appears on the "Final Pay Request" (Attachment C) as Item 63. Change Order No. 1 (approved by Council on March 20, 2007) included all quantity adjustments and scope changes as of March 20, 2007 for a total additive sum of $170,389.73 to the contract amount. Change Order No. 2 includes re- establishing a five- strand barb wire fence removed during construction ($4,950.00) along East 106th Street North, the connection of a 12" DIP line north of East 106th Street North at Mingo Road ($5,242.00) which established a second source of water to the northwest corner of the city's water distribution system, re- installing two (2) Pressure Reducing Valves ($2,000.00) which were installed improperly due to a miscommunication between city officials and the contractor, and miscellaneous fittings, services and items ($6,646.99). The amount requested for Change Order No. 2 is $18,838.99. The following is a re -cap of the funding (to include approved Change Order No. 1 and requested Change Order No. 2) for this project: Original Contract: $3,848,184.63 Change Order No. 1 170,389.73 Change Order No. 2 18,838.99 Final Contract Amount $4,037,413.35 Acceptance of Project Change Order No. 2 Water System Improvements Phase II Page 3 of 17 FUNDING: Funding for this project is provided by the Oklahoma Water Resources Board as a loan from the Drinking Water State Revolving Fund. Additional funding for acquisition of Right -of -Way was provided by remaining Vision 2025 funds. The DWSRF loan application was approved for $4,643,250.00 to compensate construction, easement and right -of -way acquisition, engineering, bonding and financing costs and an allowance of $200,000. Additional funding to compensate for Change Order No. 1, in the amount of $170,389.73 and for Change Order No. 2, in the amount of $18,838.99, will be obtained from savings in right -of -way acquisition and engineering costs (approximately $500,000 savings). RECOMMENDATIONS: Staff recommends Trustee approval of Change Order No. 2 in the amount of $18,838.99, for a revised contract amount of $4,037,413.35, approval for staff to make final payment to McGuire Brother Construction, Incorporated in the amount of $30,992.00, and acceptance of the Phase II (West) Transmission Main, Booster Pump Station and Pressure Plane Appurtenances Project.
