Applicant will coordinate with and get agreements for all encroachments and work within the large Xcel Energy easement through the site. Stormwater Management 9. The site is meeting water quality requirements primarily through water reuse for onsite irrigation. The remaining water quality required will be provided by the stormwater ponds onsite. a. Applicant should provide documentation noting that the water quality treatment needed for Phase 1 is being provided by either the irrigation system that will be constructed as part of Phase 1 and/or the ponding onsite that is being constructed as part of Phase 1 to confirm water quality requirements are being met in the interim condition. 10. The site is meeting rate control requirements through the stormwater ponds onsite. 11. Additional permitting with both RCWD and DNR Floodplain/FEMA is required for the culvert crossing in the ditch. The applicant has noted coordination for both permits is underway. a. While it is not a public ditch, the private ditch is considered a Regional Conveyance System under RCWD’s definitions and will requires a Rule G permit administered by RCWD. The Rule G permit must be obtained prior to the start of construction on the culvert crossing. b. The Minnesota DNR staff has noted a LOMR for the crossing will be required within 6 months of the crossing construction. 12. While the information previously reviewed confirms the viability of the stormwater reuse system, additional detail on the irrigation system is needed for review. Details on where the intake pipe will be laid and at what elevation, in addition to the location of the main line for irrigation should all be provided as the project moves forward. An irrigation plan has not been received for the development as a whole or for Phase 1. 13. Additional detailed redline drainage comments have been provided to the applicant and will need to be addressed prior to the issuance of the stormwater permit. Wetlands 14. While not part of the plat plans, the applicant is encouraged to submit a drawing and narrative describing the installation of hydrology monitoring equipment for wetlands 2,3, and 6 prior to the 2023 growing season as required under condition 1 of the wetland replacement approval issued on June 24, 2022. 15. Condition 4 of the replacement plan approval states that the approval itself is contingent on a take permit being issued by MN DNR or other agencies. The last correspondence from the applicant’s representative stated that there has been no response from the MN DNR since 8/2/22. A take permit will be required prior to any ground disturbance activities. The purchase of replacement credits has been held up due to this as well. Replacement credits need to be debited from the approved wetland bank (#1762) prior to impacting wetlands. 16. Prior to constructing the trail crossing wetland 6 east of the intersection of 158th Blvd and Street G, details on the boardwalk will need to be provided for approval by the Hugo Technical Evaluation Panel (Condition #5 of the Replacement Plan approval).
