Page 7 of 13 square feet as a result of the additional parking. In addition, the updated plan provides for 9,234 square feet of perennials and shrubs by adding an additional 455 plants mainly within the proposed expanded parking area. The types of plantings are a variety of species consistent with the previously approved landscape plan. I. Drainage Wetlands and Flood Plain – Section 1325.05 Subd. 2 – Meets Requirements Subject to Recommended Conditions The City Code requires stormwater management be provided to meet water quantity, infiltration, and water quality requirements. The project was previously approved for construction of three (3) stormwater ponds. The first pond is located in the middle of the loading area. The other two (2) ponds were to be located adjacent to 694 and 35W. The proposed parking lot expansion would be constructed in the general area of the previously identified pond adjacent to 35W. It was noted in the October 2020 Staff Report that when the proof of parking stalls are needed that the Applicant would need to construct an underground retention area in the same area to replace the existing stormwater pond located adjacent to 35W. The Applicant as part of this Site Plan Review is proposing to construct an underground retention system. The Public Works Director/City Engineer has completed the initial review of the underground retention system design and infiltration rates with regards to potential impacts of existing wetlands, public versus private runoff, and access to nearby utilities and easements. The parking lot expansion from a zoning review may seem simplistic, but that far be the case from a Public Works/Engineering standpoint given the complexity of this design and parking lot location with the logistics of easements, wetlands, and stormwater maintenance. Planning Staff has included reference to the Public Works Director/City Engineer preliminary comments under Additional Review and as a recommended condition of approval. This comment letter was given to the Applicant and they have indicated they are working to prepare responses and/or plan revisions necessary to address these items. In addition, the Applicant has indicated that the updated site plans and underground retention systems plans have been submitted to the Rice Creek Watershed District, but they have not received a comment review letter or approval from the Watershed. Therefore, Planning Staff recommends City Council consideration of a condition of Site Plan Review would be subject to approval of the Rice Creek Watershed District. Lastly, it should be noted that upon the determination of the Public Works Director/City Engineer that the proposed plans would be compliant then the Applicant would be required to apply for a separate land disturbance permit for construction of the parking expansion area. This work may not be completed under any of the previously issued permits for this project. Prior to the issuance of a land disturbance permit for the parking lot expansion area, the Applicant shall submit an amended operation and maintenance plan for the long-term care of all onsite stormwater facilities subject to the satisfaction of the City Engineer. Staff has made multiple requests from the Applicant for submittal of an amended stormwater maintenance plan for Engineering/PW review. The Applicant has indicated at the time of writing this report that this plan is not yet complete. The stormwater maintenance plan will also require review of the City Attorney prior to approval of the City Council. This agreement needs to be fully executed prior to issuance of the land disturbance permit.
