Cleanouts are shown on the sanitary lines greater than 100’ (B1L3 and B2 L1-2) • Transportation The Eastside Villas development proposes one 28-foot (back-to-back) street extension from the existing Dogwood Street ending at the future Butternut Street extension. The street would include 2 eyebrow curves with 46-foot back of curb radii and 4 lots adjacent on each curve. A Noise Study Report was also prepared by David Braslau Associates regarding the noise pollution caused by adjacent traffic along Interstate-35E. Comments: 1. The applicant shall adjust height of the sound wall to the recommended 936 feet. 2. The applicant shall submit details for the construction of the sound wall. The sound wall shall be constructed using MnDOT specifications and approved materials. Sound wall details are shown on sheets S1 and S2. 3. The City’s Comprehensive Plan identifies a future overpass of Cedar Street over I-35E. This will likely require a retaining wall at the existing south right-of-way edge of Cedar Street. Comment noted. 4. The applicant shall provide street grades with final construction plans. Street grades are shown on the final plans. 5. The applicant shall provide signs on Butternut Street to indicate “Future Road Extension.” Future road extension sign noted on final plans. 6.

The applicant shall adjust the crest and sag curves in the roadway to meet minimum curve lengths (minimum 25 MPH road, 30 MPH preferred). K value’s have been added to the profile.
