Benson, City Engineer ~ DATE: March 6, 2000 SUBJ: Authorize Preparation of Feasibility Study for BC-7 Trunk Sanitary Sewer and BC-8 Trunk Sanitary Sewer and Lateral Watermain Improvement Project No. 00-01 The City of Chanhassen has received petitions trom Mills Properties, Inc., Paul and Paula Savaryn, and Westwood Community Church to conduct a feasibility study for the extension of trunk sanitary sewer improvements for the BC-7 sewer sub district and the BC-8 sewer sub district which will include lateral watermain improvements in the BC-8 area. The Mills and Savaryn properties are currently proposed for development by Pulte Homes. The Westwood Community Church property is located west of Highway 41 in the BC-8 sewer sub district. Additionally, property owners west of Trunk Highway 41 have expressed an interest in obtaining city sewer and water service; however, they have not formally submitted a petition. The BC-7 and BC-8 sewer sub districts were brought into the MUSA area for the year 2000 with the City's recent comprehensive plan update. The BC-7 trunk sanitary sewer improvements are included in the city's five-year capital improvement plan for the years 2000 and 2001. The BC-8 trunk sanitary sewer improvements are included in the city's five-year capital improvement plan for 2002. The TH 5/West 78th Street improvement project will extend trunk sanitary sewer to the west side of Galpin Boulevard and watermain to the west side ofTH 41. Developmenfõf property owned by the petitioners and the proposed Project 00-01 will need to be coordinated with the TH 5/West 78th Street project. MnDOT is responsible for administering this project which currently has a contract letting date of May 26, 2000. Recognizing the potential cost-saving benefits of combining the BC-7 and BC-8 sewer sub districts and lateral watermain improvements in the BC-8 area in one feasibility study, I requested proposals trom engineering firms to prepare a feasibility study which allows these projects to proceed as one stand-alone project or as two separate projects. The following table represents the proposals received trom the four engineering firms responding to the request for proposals. SEH, Inc. declined to submit a proposal for preparation of the feasibility study. , City o(Cbanha"",.

Bonestroo, Rosene, Anderlik & Associates has submitted a proposed cost which is significantly less than the other firms. This is primarily due to the familiarity Bonestroo has with the city gained through updating the comprehensive sewer and water policy plans, and past experience on previous similar projects with the city. A request for proposals to provide design and construction administrative services has been sent to consulting firms as indicated in the attached proposed project schedule. I recommend the City Council authorize Bonestroo, Rosene, Anderlik & Associates to prepare the feasibility study for the BC-7 Trunk Sanitary Sewer and BC-8 Trunk Sanitary Sewer and Lateral Watermain Improvement Project No. 00-01 as outlined in their proposal dated March 1,2000. This authorization is contingent upon the petitioning owners executing the attached feasibility study agreement to fund preparation of the feasibility study. Attachments: 1.

City Engineer City of Chanhassen 690 Coulter Drive Chanhassen, tvfN. 55317 Dear Ms. Benson, I am writing on behalf of Westwood Community Church to initiate the petition process for the extension of sewer and water to the west side of State Highway 41 at or about the 78th Street (service road) intersection. In a recent meeting with Kate Aanenson, she suggested that we confirm our current intent to obtain sewer and water connections to our future building site. As I believe you are aware, the church owns roughly 57 acres which lies north of the University of Minnesota Landscape Arboretum property and south of Camp Tonadoona. At present, our plan is to proceed with building construction in 2000/2001. While the architectural selection process is nearing completion, a firm will be engaged by August I, 1999. I am sure the architects will pursue this matter with you once they are on board. Please advise me of any formal documentation or other process which needs to be initiated to achieve our objective of obtaining City sewer and water within the time frame set forth above. If you have any questions, please contact me. Once again, thank you for your assistance in this matter. Sincerely, ~c44~é James C.

As part of this expansion, the City was petitioned to extend utilities to its Upper 81uff Creek Sanitary Distrid. 80nestroo prepared a preliminary report to serve the Upper 81uff Creek Distrid. The report evaluated various alternatives. The recommended alternative consists on combination of lift stations, forcemains, and gravity sewer. The total estimated average daily flow from the distrid is 2.49 MGD. In 1992 the City retained 80nestroo to design a major portion of the proposed facilities. The design was particularly challenging due to the existence of many wetland areas and the existence of unsuitable subsoils. The final design consisted of: · 11,700 feet of 1 2 inch diameter pipe · 2,300 feet of 18 inch diameter pipe · 3,500 feet of 21 inch diameter pipe · 5,400 feet of 24 inch diameter pipe · 4,900 feet of pipe piling · 2,000 feet of 18 inch diameter force main, and · a 4,500 gallon per minute lift station. The low construction bid for the project was 52,352,000. The low bid was within 0.5 percent of the engineer's estimate. Construction on the project began in Odober 1992 and was completed in June 1993. J J Upper Bluff Creek Dlstria Trunk Sewer - Chanhassen ;; BOfIe!mvv. Roselle. AmJer/ik and A.5soäates, ¡fie Orono: Three Collection System Projects o North Long Lake/Long Lake Country Club Sanitary Sewer The purpose of this project was to provide sewer to two existing neighborhoods located within the shoreland area of Long lake. All properties within the project area were served by individual on-site septic systems. Many of these septic systems were identified as either non-conforming or failing. The non-conforming systems failed to meet a three-foot separation between the system drainfield and the seasonal high water table. These failing systems were not functional and showed evidence of surface discharge. Average lot sizes within the project were less than one acre, and the existing topography was wooded with steep slopes. The small lot sizes and steep terrain made it difficult or impossible for most properties to find an alternate septic site. Approximately 50 properties were served by this project. The final design included a combination of gravity and low pressure systems. Gravity sewer was utilized wherever practical. Approximately 10 properties located near the lakeshore were served by individual residential grinder stations. These individual low pressure systems pumped into a trunk gravity line. Two City owned lift stations were constructed to convey flows to an existing gravity sewer. Long cul-de-sacs and narrow roads presented construction challenges. Local and emergency vehicle access was maintained throughout the project despite an extremely wet July. Construction methods included open cut and directional boring. PVC pipe was used for the open cut gravity sewer installations; HDPE pipe was used for all directional bores. Directional boring was used to install 4" forcemain, 1 'h" low pressure services, 4" gravity services and 8" gravity trunk and lateral lines. The overall project was successful in several ways. It was completed on time, eliminating failing septic systems in a timely manner. The final project costs were under budget, minimizing City costs and property assessments. The sewer installation alleviated environmental concerns, provided new streets, and freed up valuable land for home additions and site improvements to the individual properties.

AnJer/ikif!idAssociales, IIIC o Brackett's Point/Bay Ridge Sanitary Sewer The two project areas lie along the shores of Lake Minnetonka. Brackett's Point is located on a peninsula between Brown's and Smith Bays. Bay Ridge is approximately one mile south of Brackett's Point along the shoreline of Smith Bay. Both neighborhoods were fully developed and all properties were served by on-site septic systems. Residents from both neighborhoods petitioned the City to provide sanitary sewer. Non- conforming or failing septic systems along with the proximity to the lakeshore were the primary factors the City considered when ordering the project. Each neighborhood offered a unique set of design obstacles: Brackett's Point with its long cul-de-sac, poor soils and little topographic relief; Bay Ridge with its proximity to the lake and heavily traveled county roads. Easement acquisition was necessary and difficult for both sites. Members of both neighborhoods were included in the design process. Both neighborhoods wanted a gravity sewer system despite the substantial additional cost as compared to a low pressure system. Twenty-two properties were served by municipal gravity sewer and property on the lakeshore had to be served by a low pressure system. The Bay Ridge project served eight properties. An 8" PVC gravity trunk sewer was installed through the backyards. The sewer location was determined by the property owners, based on locations of the septic systems and ease of hook-ups. The backyard alignment required the contractor to use extreme care during construction to protect elaborate landscaping. A City-owned lift station was constructed as part of the project. A 3" HOPE forcemain was then directionally bored from the lift station to an existing gravity manhole. Construction of the sewer on Brackett's Point required considerable coordination to maintain residential access throughout the project. Construction methods were dictated by the need for access, a high water table, and poor soils (peat and marl). Extensive directional boring was used on this project. Approximately 2000 feet of 8" HOPE gravity sewer was directionally bored. Because of the topography, much of the sewer was installed at minimum grade. The gravity system routed flows to a lift station constructed as part of the project. Lift station design needed to be coordinated with the MCES as flows needed to be pumped into an existing 20" MCES forcemain. Negotiations with project and non-project residents were successful in the acquisition of some difficult easements necessary to construct the projects. Both projects were completed on time and within budget.
