Date: May 3, 2013 Re: Metro Transit Preliminary Plat Review WSB Project No. 2029 -55 701 Xenia Avenue South Suite 300 Minneapolis, MN 55416 Tel: 763 - 541 -4800 Fax: 763 -541 -1700 The following review is based on these submittals: 1. Preliminary Plat for Alino Addition prepared by SRF Consulting Group dated April 9, 2013. 2. Construction Plans for Metro Transit prepared by EVS received on April 17, 2013. Preliminary Plat Comments: 1. It should be noted that the design for 21st Avenue has not yet been initiated. The design of 21St Avenue will likely necessitate easements for storm water ponding, pedestrian trails, and other design features on Lot 2 Block 1. The property owner will need to agree to provide these easements once they are identified. 2. The proposed right of way dedication for the extension of 21st Avenue must be increased to 60 feet in width from the intersection with CSAH 14 north through the proposed full access intersection. This is necessary to accommodate the 21st Avenue improvements. North of the full access intersection the right of way can be reduced to 40 feet. 3. It should be noted that there will only be allowed one full access intersection with 21st Avenue for the entire site. Therefore, the proposed full access will need to serve not only the Metro Transit facility but the remainder of the site. A second right - in/right -out access maybe allowed to the south in the future when the balance of the site develops. 4. The location of the proposed full access intersection with 21st Avenue does conform with the City's access spacing guidelines. However, the proposed location will result in wetland impacts when the private roadway is extended east in the future to serve the balance of the property. The property owner will need to obtain the necessary approvals from all governmental agencies with jurisdiction over that wetland prior to any impacts. 5. The drainage and utility easements shown on Lot 1, Block 1 will need to include the proposed storm water pond. 6. The applicant will need to provide evidence of approval from the Technical Evaluation Panel for the wetland delineation that was completed per the report dated April 2012 prepared by SRF. Confirmation is needed to ensure that the proposed drainage and utility easement is sufficient.
