John Rask (M/I Homes) submitted an application requesting approval for wetland impact sequencing and replacement. The application was considered complete on March 17, 2022, and a subsequent notice of application was issued on April 4, 2022. The comment period for the application expired on April 26, 2022; no comments were received. The purpose of the project is to create a mixed housing type, residential community consisting of 218 residential units, a large borrow pond (identified as Lake 1000), and a trail which incorporates a boardwalk system (see map). A wetland boundary and type application was approved on September 25, 2020 and was issued on January 18, 2021 for the western half of the project area and separate Notice of decision was issued in 2017 approving the wetland boundary and types for the wetlands on the eastern half of the project area. Collectively, these two approvals identified eight (8) wetland basins within the project area. Vegetative communities represented by these wetlands include seasonally flooded basins, wet meadows, and scrub-shrub wetlands. They provide the following wetland functions: •Surface water detention •Nutrient Transformation •Carbon Sequestration •Sediment and Particulate Retention •Waterfowl and Waterbird Habitat •Other Wildlife Habitat Multiple alternatives were considered for this project to avoid and minimize impacts to wetlands. The total amount of impact to on site wetlands using the preferred alternative is 0.9519 acres. This amount of impact must be replaced and is proposed to be replaced using wetland bank credits. The required wetland replacement ratio is 2.5:1; however, the proposed wetland bank is G.15
