7 <br /> <br />Tree Preservation and Landscaping <br /> <br />The Environmental Coordinator and Environmental Board reviewed the tree preservation and <br />landscape plans for the entire development during the preliminary plat approval process. The <br />2nd Addition landscape plan has been reviewed by the Environmental Coordinator and is <br />consistent with the approved preliminary landscape plan. <br /> <br />Open area landscaping around the storm water ponds were provided in the 1st Addition. <br /> <br />Buffer and screen standards apply along CSAH 54 (20th Avenue), specifically Lots 7-10, Block <br />1, 2nd Addition that have a rear frontage on 20th Avenue. Approximately 475 linear feet of <br />frontage will be screened by shrubs, new trees, and existing trees to provide a continuous <br />planting screen year-round. The 2nd Addition Landscape Plan shows trees and shrubs planted <br />on two separate berms. During preliminary plat review, it was suggested these berms be <br />combined to provide a continuous berm; however, an opening between the 2 berms is needed to <br />provide rear yard drainage. A triangulated row of coniferous trees will be planted in addition to <br />the berms that will provide appropriate screening. <br /> <br />Coniferous trees and shrubs will be planted on Outlot A along the trail corridor as required. <br /> <br />Boulevard trees are required at the rate of one (1) tree per lot frontage for single family. There <br />are 33 single family lots in the 2nd Addition that require 36 boulevard trees (interior and corner <br />lots). Thirty-six (36) trees are proposed which is compliant with the ordinance. <br /> <br />Alternative Urban Areawide Review (AUAR) <br /> <br />The site is not within the 2005 I-35E Corridor AUAR; therefore, no mitigation is required. <br /> <br />Traffic Study <br /> <br />A Traffic Study was prepared by Spack Solutions on December 6, 2019 and reviewed during <br />the preliminary plat process. It was determined that Nadeau Acres meets transportation <br />guidelines in regards to traffic volume, traffic capacity and level of service. <br /> <br />Wetlands <br /> <br />Kjolhaug Environmental Services Company, Inc. prepared a Wetland Delineation Report dated <br />October 29, 2019. A Notice of Decision was issued by RCWD on December 11, 2019. <br /> <br />Kjolhaug Environmental Services Company, Inc. prepared a Wetland Permit Application dated <br />December 23, 2019. Per the report, two (2) wetlands were delineated on site totaling 1.37 <br />acres. Wetland 1 is a Type 1 wet meadow wetland. Wetland 2 is a partially-drained, wet <br />meadow and scrub-shrub wetland. A portion of Wetland 2 southwest of the septic mound <br />discharge outlet was created in upland and is incidental. <br /> <br />The proposed project will require 30,826 square feet (sf) (0.7076 acre) of permanent <br />impact to four (4) wetland areas, one of which is incidental for WCA permitting. Replacement <br />will be accomplished via the purchase of wetland banking credits.
