Ms. Rachel Juba May 7, 2020 Page 2 7. Sanitary sewer service is available to the site from the existing 18" sanitary sewer located in the intersection of 146th Street and Finale Avenue. Sanitary sewer will be extended down the proposed alignment of Finale Avenue and into the site at multiple locations. Access to Keystone Place will be required to be maintained/coordinated while this connection at the intersection is being made. 8. Water infrastructure exists within the southern portion of Finale Avenue. Watermain will be extended north along the proposed Finale Avenue alignment and connect to the existing 12" watermain stub located at the north end of the proposed Finale Avenue alignment near the well house. 9. The Hugo Fire Department has reviewed the site for hydrant placement and emergency vehicle access. Staff has provided detailed redline comments on the plans requesting some minor modifications and requests for information. 10. An existing stormwater outlet from the stormwater pond located in Keystone Place extends through the proposed site. The plans show relocation of this outlet pipe that will require vacation of the existing drainage and utility easement. A drainage and utility easements will be required to be placed where the relocated Keystone Place stormwater outlet is placed. 11. Drainage and Utility Easements already exist west of the proposed site improvements where wetlands and stormwater management features are proposed. 12. Drainage and utility easements will be required for the sanitary sewer, watermain, and storm sewer (only public portion that extends from Finale through the site). The City will be responsible for maintenance associated with the sanitary sewer and water mains, not individual services. 13. Easement widths should be a minimum of 20-ft wide, or a width of twice the depth of the pipe, whichever is greater. 14. Detailed redline comments have been provided on the plans and sent to the applicants engineer so they can be addressed in future submittals. Stormwater Management 15. The applicant has submitted a draft of their Stormwater Management Plan for the site. The applicant is proposing to use a stormwater pond to meet stormwater requirements for this site. Based on the information provided it is unclear if rate control and volume control requirements are being met at this time. The design of the outlet of the pond is required to confirm rate control requirements are being met. It does appear that the applicant will be able to meet these requirements. Additionally, it will need to be confirmed that infiltration below the outlet of the pond is being proposed to meet volume control requirements as indicated in the model. Soil borings for this pond location will be required. 16. Staff has been developing a document called the Comprehensive Stormwater Management Plan that contains a credit and tracking system for water reuse projects within the City. These credits that have been generated can then be used for City projects where infiltration is not feasible. These credits can also be sold to development projects in instances where infiltration is not feasible. 17. As part of the City's Comprehensive Water Resource's Management Plan, there are a number of additional water reuse projects that the City is interested in pursuing. The City is currently planning for the construction of a water reuse system that would take stormwater from the pond located in the northwest quadrant of Oneka Parkway and CSAH 8. This project is proposed to irrigate the CSAH 8 median and boulevard areas, Lions Park, City Hall, Finale Boulevards (new segment) and 1471" Boulevards (new segment). To fulfill infiltration requirements, Hugo Gardens is proposing to participate in the costs associated with the water reuse project. Since this water reuse system will not be in place at the time of project approvals, use of the credits generated from previous water reuse projects could be used for this project. The Comprehensive Stormwater Management Plan is currently being finalized
