An application for wetland replacement, sequencing flexibility, and a no -loss was received from Kelly Kunst, Westwood Professional Services, on February 23, 2017. The LGU requested additional information to make the application complete, which was provided by the applicant on March 8, 2017. subsequent Notice of Application was issued on March 25, 2017. I_1 A pre -application TEP meeting was held on October 26, 2016 to discuss the site design, potential impacts, and impact mitigation. A wetland replacement plan application was submitted in December 2016, but was later rescinded due to changes in street layouts that altered impact quantities. The Adelaide Landing project is a 220 acre residential development which will result in the construction of 230 single family lots and 83 detached villas over the course of five (5) phases, which is proposed to begin this year. Previous wetland delineations show that five (5) wetlands occupy almost 57 acres or 25% of the site. The construction of residential roads, an ADA compliant trail, two (2) water crossings, and housing sites result in seven (7) separate impacts totaling 1.32 acres. Avoidance The applicant provided one alternative that would avoid all wetland impacts on the site. This alternative was the no build alternative. This alternative was rejected as it would not fulfill the basic purpose of the project nor fulfill the need defined in the City of Hugo's Comprehensive Plan to provide suitable housing options for an increasing City of Hugo population. Minimization The applicant has worked to minimize impacts to on-site wetlands through adjusting lot configuration, road locations, and increasing slopes. Through this process the applicant has minimized wetland impacts to 2% of the nearly 57 acres of wetland that occupies the site. Impact 1 was minimized by increasing side slopes from 3:1 to 2.5:1, and decreasing road and shoulder widths. Impact 2 is necessary to accommodate an ADA compliant trail, the road, sidewalk, and road shoulder. Earlier designs did not have the road in this location, but City Ordinance required the roadway be shifted south. This pushed the roadway south and west, resulting in impact 2. Impact 3 occurs across a thin, linear portion of wetland 2 that forms an east -west connection from wetland 2 to an adjacent parcel. 137th Street South crosses hereto provide access to the southern portion of the development. Without the crossing, a long cul de sac would exist north of this crossing, which may increase travel times for emergency personnel to access the southern portion of the site. Adjacent housing sites would be elevated 8-10 feet above the wetland on three sides, posing a potential safety issue and reducing the functionality of the wetland in this site. To maintain hydrology, a 15" culvert will be installed in this location. Impacts 4, 5, and 6 result from the extension of 137th Street South to provide safe egress and north to south through the development. The applicant minimized impacts by taking advantage of a existing field road crossing, minimizing road width, maximizing road slopes, and shifting the road alignment. This was done in response to TEP comments at the pre -application meeting. The changes resulted in a 8,000 sq. ft. reduction in wetland impacts. Additional minimization includes the elimination of 425 sq. ft. of impact to wetland 2 in the eastern portion of the site due to the installation of a stormsewer pipe. The pipe inlet was shifted to completely avoid wetland impacts. In addition, wetland buffers will be maintained throughout the site to protect remaining wetland acreage.
