PROJECT INTRODUCTION This report examines the proposed watermain and sanitary sewer improvements along Mainstreet from 5' Avenue to 11' Avenue. This work is proposed to be completed as part of the 2015 Mainstreet Improvement Project. Consistent with City policy, the pavement rehabilitation costs of the project are not proposed to be assessed to adjacent property owners. Similarly, the costs of replacing the watermain is also not proposed to be assessed to adjacent property owners. Therefore, this report is intended to focus solely on water and sanitary sewer service work that is intended to be assessed consistent with City policy and as allowed by MN Statute 429 for Special Assessments. BACKGROUND Preliminary plans for pavement rehabilitation and reconstruction along Mainstreet from 5' Avenue to 20' Avenue in the City of Hopkins were initiated in January, 2014. Following discussions with City Staff and area property/business owners, regarding the current age and size of watermain between 11' Avenue and 5' Avenue it was decided to add this six -block stretch of watermain replacement to the project scope. Along with the watermain replacement, water services and sanitary sewer service connections were also evaluated. There are multiple properties in the project area that do not have their own utility services connection from the sewer main but instead share a common service from the main. Consistent with past practice in Hopkins, water and sanitary sewer services are proposed to be funded in part by special assessments and are eligible given their ownership by each individual property. This report, and the public engagement processes utilized to produce it, will be used as the basis for final design. This report is also a required step in the State of Minnesota Chapter 429 process for special assessments. EXISTING CONDITIONS The existing watermain along Mainstreet is 12" diameter ductile iron pipe to the west of I Ith Avenue. This main was installed as part of a 1991 reconstruction of Mainstreet and provides adequate capacity for projected downtown redevelopment. The 1991 project did not address watermain between 11' Avenue and 5' Avenue. The existing watermain between I Ith and 5`h Avenues is 8" cast iron pipe and was installed in the early 1950s. Given the 60+ year age of the existing watermain, the benefits of matching size of the 1991 main west of I Ith Avenue, and opportunity for improvement and redevelopment created by the project, it was determined replacement of the watermain between I Ith and 5t' Avenues is appropriate and was included in the scope of the project. Service lines in the watermain replacement area range from 3/4 -inch to 2 -inch for domestic lines and 2'/z -inch to 8 -inch for existing fire service lines. Several properties do not have an existing fire line. Water service pipe materials may be copper, galvanized steel, lead, or ductile iron pipe. 2015 Mainstreet Improvements Prepared by: Bolton & Menl4, Inc. City of Hopldns, MN Page 1 July 30, 2014 2"N" 41"NUTH10111RIVIA" 14, MR', 1011" 41"41,11110,R2,1111" 41201, The existing sanitary sewer main varies between 8 -inches and 15 -inches. The original material was clay but a fair amount of the sewer main has been lined with a cured -in -place -pipe material that was installed in the early 1990s, at least partly with the 1991 reconstruction project. It is unclear at this time whether private agreements exist between properties to share, maintain, and ultimately replace these service lines. 4. PROPOSED IMPROVEMENTS As noted above, it is proposed to replace the 12 -inch watermain along Mainstreet from 5t' Avenue to I Ith Avenue. Due to a history of leaks at connections made to existing services within the roadway, the City of Hopkins requires connections be made at the property line, or if not feasible, as close to the property line as possible with the goal of at least extending the service outside the new roadway. Additionally, with expanding fire codes it is ideal that each property be provided a service capable of supplying water service meeting current and hopefully meeting future fire codes. Therefore, it is proposed to replace all water services between 5' Avenue and 11 `r` Avenue, and provide fire lines for each property. It is noted the bulk (26) of the water services are located between $t` Avenue and I Ith Avenue, with an additional three proposed service lines between 5t' Avenue and 6t` Avenue. Proposed water services typically include a 6 -inch ductile iron pipe (or 8 -inch if one exists). The service line extends from the 12 -inch main line to approximately 10 feet behind the back of curb where it will then be connected to the existing water service if one exists. If multiple service lines (domestic and fire) exist today at a property, connection will be made to both lines from the new service line. At addresses which share service with another address today, a water service will be stubbed out so it can serve that address when at such time it is needed either due to redevelopment, property split, or infeasibility of replacement of the shared line within the building. This improvement will make service available to serve each property without need to impact Mainstreet should those conditions present themselves in the future The need for additional sanitary sewer service stubs for potential redevelopment was also reviewed. Review was conducted for properties which share a sanitary service with another property today, similar to proposed water service stubs. Consideration was given to installation of a new sanitary sewer stub to provide service at such time it is needed either due to redevelopment, property split, or infeasibility of replacement of the shared line within the building when it becomes necessary. The results of this review noted that no properties are in need of a new sanitary sewer service. Twenty nine properties will have water services replaced or added as a part of the project. Figures 1 and 2 illustrate properties that are proposed to have water services replaced or installed as a part of the project. Preliminary plans are provided to illustrate the proposed work. 2015 Mainstreet Improvements Prepared by: Bolton & Menk, Inc.

PROPERTY OWNER MEETINGS & PUBLIC ENGAGEMENT Public input on these improvements has been taken through neighborhood questionnaires, public meetings, and ongoing routine communication such as in-person and over the phone discussions. An informational meeting was held on July 2, 2014 to discuss proposed assessments. Four property owners attended. The format of the meeting included a presentation and the project team fielded questions and comments voiced by attendees throughout the presentation. The presentation provided an overview of the project and a review of the proposed water and sewer service replacement consistent with the content of this report. A range of estimated assessments amounts between $3,200 and $7,000 per service line, with an average of $4,500 per service line. It was noted some properties may carry multiple service lines. Two attendees also returned comment cards/questionnaires with information about their property. In general, attendees did not express concern about the water service replacement with regard to their necessity or estimated cost, but seemed surprised to learn water and sewer services are owned by individual property owners from their building to the mains in the street. None of the property owners in attendance knew whether their service was shared with another property. The project team also noted the complexity of the sewer and water service layout on Mainstreet and that information presented at the meeting was subject to change based on information provided by property owners regarding their utility service needs and other ongoing research. The attendees were informed additional mailings and meetings with the City Council would be forthcoming. Contact information for questions and concerns were also provided to the attendees. 6. ESTIMATED COSTS Estimated construction costs for the water services were calculated utilizing recent bid prices for projects with a similar project scope. Final costs and assessments will be determined using construction costs of the proposed work based on bids by the lowest responsible bidder for the project as a whole. The estimated construction cost of the water service improvements is $119,775.00. The estimated cost of the each water service replacement is between $1,650 and $6,150, varying based on the estimated length size of service pipes. The average preliminary assessment amount is roughly $3,900 over the 29 proposed properties to be assessed. The preliminary assessment roll is attached as Appendix A. The estimated costs and preliminary assessments are based on public construction cost information. Since the consultant has no control over the cost of labor, materials, competitive bidding process, weather conditions and other factors affecting the cost of construction, all cost estimates are opinions for general information of the City and no warranty or guarantee as to the accuracy of construction cost estimates is made. It is recommended that costs for project financing should be based upon actual, competitive bid prices with reasonable contingencies. 2015 Mainstreet Improvements Prepared by: Bolton & Menk, Inc.

PROJECT FUNDING The watermain improvements will be paid for 100% by the City with its utility fund. Service lines are owned by the individual property owners. For commercial properties, City Policy dictates 100% of the cost of service replacement be the responsibility of the property owner. 8.
