any clearing activities will need to occur outside of April 15 to July 15 due to concerns with potential introduction of oak wilt to the area. Due to the size of the Subject Property and the limited areas of site disturbance, the Applicant had proposed limiting the tree inventory to just those designated areas of potential impact. This approach seemed reasonable and was approved with the understanding that the project must still comply with the tree preservation standards in City Code (retaining at least thirty percent [30%] of the significant tree diameter at breast height [DBH] inches on site). Based on the submitted Tree Inventory and Preservation Plan, approximately 64% of the existing significant tree Diameter at Breast Height (DBH) inches will be preserved. Again, this only includes the trees that were inventoried (only those that were in areas of proposed disturbance), there are many more trees on the Subject Property overall, meaning that an even greater percentage of tree inches are actually being preserved. Wetlands and Floodplain There are both wetlands and floodplain on the Subject Property. Approximately thirty (30) acres of the Subject Property contain either wetland and/or floodplain. The floodplain is designated as General Floodplain, meaning that there has not been detailed modeling done to determine Floodway and Flood Fringe boundaries. However, as long as there are no proposed buildings within the floodplain boundary, which there are not, additional modeling is not required. Staff is working with the MN DNR Floodplain staff to verify that the proposed driveways and public road are pennissible (they do cross the floodplain boundary). The developer will likely need to provide documentation that neither would create a rise of more than 0.5 feet. Additionally, the developer will also need to provide documentation that no driveway, nor the public road, will be more than two (2) feet below the Regulatory Flood Protection Elevation. A wetland delineation has been completed. The Preliminary Plat does include the required sixteen and a half foot (16.5') wetland setback; however, it appears that the drainage and utility easements need to be adjusted to encumber these areas. There will be some minimal impacts to wetlands on some lots (Lots 3-5), simply due to needing the driveways to access buildable locations on each of the lots, as well as the public road. Wetland mitigation will be necessary and will be reviewed and addressed by the Lower Rum River Watershed Management Organization (LRRWMO). Park Dedication and Trail Fees The recently completed 2040 Comprehensive Plan notes a 'Community Park search area' to the southeast of the proposed plat, and this, coupled with low densities of Williams Woods do not warrant the land dedication for a neighborhood park. Additionally, a trail is not being proposed with 173rd or 175th Avenue at this time —nor within the plat. (At the time of the street's reconstruction, a off -roadway trail, or a paved bike lane should be considered.) The 2021 Park Dedication rate is $3,500 per dwelling unit, and Trail Fee $1,000. Funding Source: All costs associated with this request are the Applicant's responsibility. Recommendation: Based on discussion/staff recommends cash contributions to satisfy Park Dedication and Trail Fees based upon the number of lots, in an amount calculated at the time of Final Platting.
