BWSR NOD Form – November 12, 2019 2 project involves the creation of 59 residential sites. The application was considered complete on April 1, 2022, and a subsequent notice of application was issued on April 5, 2022. Wetland boundaries and types were approved for this 70-acre parcel on January 17, 2022. Six (6) wetland basins were identified as part of the approved wetland delineation. Many of these wetlands are type 2, with some type 1, 3, and 4 existing on the property. Wetlands are found across the property and the property has experienced ground disturbance and changes to wetland hydrology and drainage over many years. The proposed wetland impacts facilitate the development of 59 residential lots with streets and infrastructure which is mainly confined to the northern half of the property; leaving the large wetland complex in the southern portion of the parcel undisturbed. The purpose of the project is to provide residential housing in an area with a housing deficit. The total amount of proposed impact based on the preferred alternative is 0.5323 acres across four (4) individual wetlands. Wetlands B and C, within the western portion of the project will be impacted in their entirety via mass grading of the site (0.4286 acres combined). Additional impacts will occur to wetlands F1 and F (0.1 acres combined). Sequencing/Sequencing Flexibility Four (4) alternatives were considered as part of the sequencing requirement under MN Rule 8420.0520. The first was the no-build alternative. This alternative was rejected as not developing the site would not meet the project purpose, the upland area of the site is zoned for residential development and development would aid in meeting the residential housing deficit within the region, denial of the use of the 33.57 acres of upland with 0.53 acres of impact to degraded wetlands does preserve any significant wetland functions, and the development project will facilitate the restoration of the 33 acres of wetlands to the south. Alternative 1 was developed with input from the City of Hugo and included the extension of 134th Street across the parcel and increased the number of lots to 62. This alternative resulted in 1.24 acres of wetland impact and was rejected. Alternative 2 was developed with input from the TEP and involved rerouting 134th Street to the north and included 60 lots. Wetland impacts for this alternative were 0.98 acres. This alternative was also rejected. The selected alternative eliminated the alignment of 134th Street and utilized cul de sacs and existing road stubs to provide access to the site and individual lots. This resulted in a 60% reduction in wetland impacts from the first alternative described. The applicant also requested sequencing flexibility for all impacted wetlands (B,C, F, and F1). To support this, the applicant has submitted a MnRAM analysis. Wetlands B and C ranked low to moderate for most all of the functions with the exception of downstream water quality maintenance, which was high due to their isolated nature. Wetland F and F1 ranked consistently low to moderate for all functions (4 low rankings and 5 moderate). Observations made during the TEP field review confirms the degraded nature of these wetland basins. Replacement The proposed alternative will result in 0.53 acres of permanent wetland impact in the form of wetland fill. The required replacement ratio is reduced from 2.5:1 to 2:1 as the applicant will be required to replace within the same Major watershed (MS-Metro-#20) and same BSA, which is BSA #7. To meet this requirement, the
