Floodplain <br />The 2015 FEMA floodplain map indicates Zone A floodplain along the west edge of the site. <br />However, a Letter of Map Revision (LOMR) was obtained on December 21, 2016 for the entire <br />NorthPointe development. The floodplain boundary was revised and is no longer on the site. <br />Noise Study <br />A Traffic Noise Assessment for NorthPointe Garden Estates was completed on January 5, 2022 <br />by David Braslau Associates, Inc. The report evaluated 1-35E noise compared to daytime and <br />nighttime noise standards. Noise standards are met under the following conditions: <br />1. The building shall be constructed in such a way that the exterior to interior sound level <br />attenuation is at least 30 dB(A). <br />2. All housing units shall provide year-round climate control. <br />3. STC 30 windows shall be used for all windows. <br />4. Per page 8 of the Traffic Noise Assessment, exterior wall construction shall consist of: <br />a. APA rated sheathing located on the exterior side of the exterior wall. <br />i. This material will be 7/16" thick and a wood fiber material. <br />b. Exterior wall shall be 2x6 studs with R-21 batt insulation. <br />c. The inside finish shall be 5/8" gypsum board. <br />d. Lap siding shall have a thickness of .354" and be of a wood fibrous material. <br />e. Trim around the windows shall have a thickness of .970" and be of a wood <br />fibrous material. <br />Additional City and Government Agency Review Comments <br />MNDOT <br />MNDOT provided comments on January 26, 2022. They noted the need for possible noise <br />mitigation and a drainage permit. Noise mitigation has been addressed with building <br />construction materials as previously noted. The applicant shall apply for a drainage permit. <br />Public Safety Comments <br />The Fire Division reviewed the plans and notes the following: <br />1. An emergency vehicle access shall be provided to the north side of the building. <br />a. The developer could potentially upgrade the existing trail to provide emergency <br />vehicle access. <br />2. An addition fire hydrant along the emergency vehicle access shall be added. <br />3. The elevator cars shall be large enough to accommodate ambulance stretchers. <br />The Police Division reviewed the plans and did not identify any public safety concerns that <br />should be addressed. <br />14 <br />
