Ms. Rachel Juba March 17, 2017 Page 2 6. 130th Street is identified as a potential project in a future year, and some level of City financial participation is reasonable. The specific timing for the improvements, along with the cost share, will be included in the Development Agreement. 7. Streets 1 & 2 will cross a private ditch. The specific design of the crossing is dependent upon the hydraulic needs related to the ditch itself. We are currently collaborating with the applicant to develop a preliminary design for the crossing/culvert, and ultimately develop a final design and secure a permit from the RCWD. 8. A detailed traffic analysis was completed as part of the EAW. The results of the EAW indicate the development can be accommodated, provided a number of improvements to 130th Street are completed. The existing signal timing at TH 61 and 130th Street will also require monitoring, with potential changes made by MnDOT. Grading, Drainage, and Wetlands 9. The property includes 57.7 acres of wetlands, which have been delineated and approved by the City as LGU. The proposed development does result in 1.34 acres of wetland impact that is proposed to be impacted through wetland bank replacement. A wetland replacement application has been submitted for review. A TEP meeting will be scheduled in the near future and the notice of decision will ultimately require City Council approval. 10. Within the development there is a network of trails that do include four wetland crossings. The crossings are proposed to be boardwalks designed to qualify for no wetland loss. Staff will continue to work with the applicant on the boardwalk design. The elevated boardwalk will maintain the 8-foot width to be consistent with the trail widths throughout the development. 11. The City will review and issue a stormwater management permit for the development. The plans include managing stormwater through a combination of ponds and a stormwater reuse system. The design is consistent with stormwater rules as proposed, and we will work with the applicant to finalize the plans and issue a stormwater permit as the project moves forward. 12. Any fill placed in the floodplain requires compensatory storage to mitigate filling within the 100-year floodplain. The applicants provided detailed documentation depicting the existing and proposed floodplain, and we will continue to work directly with the applicant to finalize the details. A Letter of Map Revision will need to be prepared and submitted for FEMA approval so that the existing floodplain boundaries and elevations can be revised. 13. There are a number of Outlots included as part of the plat. Outlots that contain stormwater ponds and/or park should be deeded to the City; the remainder of the Outlots should include drainage and utility easements. 14. The plans include the installation of a stormwater reuse system to be utilized to irrigate common areas, park areas and individual lots within the development. The system is feasible from a water availability and equipment standpoint. We will finalize the technical details as the project moves forward. Of note regarding the system are the following: • The system will be installed by the applicant and pumps and mainlines owned, operated, and maintained by the homeowner's association. • The system will be a part of the overall stormwater management improvements to be included as part of the stormwater permit. The HOA documents will include provisions that will allow the City to operate the system in the event that it is necessary to maintain compliance with the stormwater permit. The provisions will include an ability to assess any City costs associated with operation and maintenance of the system.
