Ms. Katie Larsen <br />4/13/2020 <br />Page 6 <br />Nadeau Acres Engineering Review <br /> <br /> <br />lane going southbound. <br /> <br />Comments: <br />1. Anoka County is reviewing the traffic study and proposed turn lanes. It is anticipated that Anoka <br />County will require a designated southbound through lane along with a designated left turn lane <br />and right turn lane on 20th Avenue (CSAH 54). <br />Noted. This will be coordinated with the county. <br />Applicant shall show the proposed turn lane layout on both the site plan and the grading plan. <br />Anoka County will review the detailed turn lane plan for lane lengths and widths. <br />2. Update the cul-de-sac street widths to be 32-ft wide from back of curb to back of curb to meet city <br />requirements. <br />Revised. <br />3. Applicant shall realign the southern driveway entrance for 6709 20th Avenue that currently <br />provides access to 20th Avenue to Red Oak Lane. <br />Notes added to site plan. <br />Realign driveway more west ~ 100’ min from the intersection of Red Oak Lane and 20th <br />Avenue. The applicant is to coordinate with property owner. <br />4. Applicant shall show the proposed driveway for the existing house on Lot 10, Block 5. <br />Driveway added. <br />5. Red Oak Lane should have an eastbound through/left lane and a designated right turn lane at the <br />intersection of Red Oak Lane and 20th Avenue. <br />Lanes added. <br />Designated right turn lane shall be the same length as the right turn lane on Red Oak Lane east <br />of 20th Avenue. <br />6. Applicant shall identify the northern roadway limit of Heritage Avenue. <br />End of road added to plans. Grading adjusted accordingly. <br />7. City should consider the location of the pedestrian crossing at Heritage Avenue and William Lane. <br />Traffic maneuvering around the corner may not be expecting pedestrians crossing there. Options <br />to consider include extending the trail to move the crossing or moving the sidewalk to the south <br />side of William Lane and the east side of Heritage Avenue. <br />Advanced warning signs can be installed as well as a crosswalk paint markings and signage at the <br />crosswalk. Note that the turn from Heritage to William will require vehicles to slow down <br />significantly while taking the tight turn. <br />Sight lanes cannot be achieved for proper pedestrian safety. Applicant shall revise the sidewalk <br />location. <br />8. The Heritage Avenue/William Lane cul-de-sac exceeds the City’s maximum of 500-ft. This can <br />be allowed because the cul-de-sac is temporary. <br />Noted. <br /> <br />• Wetlands and Mitigation Plan <br /> <br />Kjolhaug Environmental Services Company, Inc. prepared a Wetland Delineation Report dated October 29, <br />2019. A Notice of Decision was issued by RCWD on December 11, 2019. Per the report, two wetlands <br />were delineated on site totaling 1.43 acres. Wetland 1 is a Type 1 wet meadow wetland. Wetland 2 is a <br />partially-drained, wet meadow and scrub-shrub wetland. A portion of Wetland 2 southwest of the septic <br />mound discharge outlet was created in upland and is incidental. The project area is not located within the <br />Lino Lakes Comprehensive Wetland Protection and Management Plan (CWPMP) and outside of Wetland <br />Management Corridor (WMC). <br /> <br />The applicant is proposing 0.7 acres of disturbance and will be purchasing wetland banking credits. <br /> <br />• Landscaping <br /> <br />Open area landscaping standards require 1 large tree and 3 large shrubs per 2,000 sf. Buffer and <br />screen standards apply along 20th Avenue (CSAH 54). Approximately 475 linear feet of frontage will <br />be screened by shrubs, new trees, and existing trees to provide a continuous planting screen year- <br />round. The Preliminary Landscape Plan shows trees and shrubs planted on two separate berms. <br />Boulevard trees are required at the rate of one (1) tree per lot frontage for single family. <br /> <br />Comments:
