SummarZ:of the meeting We discussed the need to obtain the services of an architect, to help with the design of the building structurally and operationally,but also to identify the design elements of the structure itself, to be communicated throughout the balance of the project, to create the harmonious planned development expected of the PUD zoning. Any plan submittal should include scaled drawings,materials and colors. We also discussed the need to provide a layout and land use plan for the western 2/3 of the property. The level of detail will dictate the level of approval. Conceptual drawings will yield conceptual approval. Engineering/Water 1. Drainage calculations provided do not follow the requirements of the 2013 MPCA Construction Stormwater Permit. Major changes to the new permit include but are not limited to the drainage volumes leaving the site not exceeding predevelopment volumes and ATLAS 14 precipitation data is to be used for all events. Please review the new requirements on the MPCA website at: hM://a°ww pca state mn us/index php/water/water-types-and- programs/stormwater/construction-stormwater/mpca-to-re-issue-construction- stormwater-general-permit.html 2. Please show adjacent property contour information to better identify how water is projected to leave the site. The east side appears to go south across the property line. 3. Per drawings dated 08/06/2013, there appears to be a low point proposed to be graded into the TH 10 ditch near proposed station 2+75. Adjust to assure positive drainage is maintained along the TH 10 south ditch line. Please provide approval from MnDOT. 4. Contours of proposed detention pond cannot extend into the proposed sidewalk. 5. The retaining wall on the west side of Yankton St should be located off of the right of way and remain of private ownership. Please include a detail of said wall. 6. Please include a detail of the trash enclosure. 7. Provide documentation showing the wetland boundary has a current certified delineation within the last 3 years. Environmental 8. Proposed storm water systems will need to adhere to the new NPDES permit requirements for storm water 9. Yankton street, the sidewalk,and the detention pond encroach into the wetland buffer. Staff supports the encroachment, due in part to the hardship caused by the existing Yankton,however, this will be highlighted during the public review.
