BrooJifield 4th Addition - Final Plat August 23, 2007 20f3 Other Lot Requirements: Trott Brook is a designated tributary of the Rum River, and is subject to Scenic River and Shoreland Management requirements. Lots along the Brook are subject to a 75-foot lot width at the OHW of Trott Brook, a 100-foot setback from the OHW, controlled vegetative cutting within this 100-foot setback, and a 25% impervious surface limitation for lots fronting the brook. The approved preliminary plat complies with all of these standards except the 75-foot lot width requirement as measured at the brook. Staffhas had discussions with DNR Staff, who explained that the intent of the Shoreland lot width requirement is to ensure that sufficient lot area is provided. Because of the large lot sizes on the Trott Brook, DNR Staff feels the intent of the requirement is being met. Landscaping: The follo'wing overall comments are offered regarding the landscaping plan dated July 26,2007: . Each lot is required to have two new trees planted in the front yard area (for comer lots, one tree should be located adjacent to each road frontage). An additional front yard tree, is required for Lots 2.9 Block 2 and Lots 4-6 Block 1. . Planting details should be included 'with the landscaping plan. A revised landscaping plan must be submitted. Tree Preservation: Tree save fencing must be installed and shall be at least at the dripline of all trees/vegetation intended to be preserved. No grading or other soil disturbance shall occur beyond this point. There appears' to be a conflict on Page C3.1 with the grading limits and the apparent dripline of trees slated for preservation (most notably on Lot 5 Block 2 and to a lesser extent on Lots 4 and 6 Block 2). This discrepancy between tree preservation limits and grading limits needs to be resolved such that the limits of grading activities coincide with the dripline of trees (a more detailed tree inventory should also help clarify this matter). Density Transition: Density transitioning is required between the proposed lots (Lots 1-9 Block 2) and the existing single family homes to the south and east. If landscaping is utilized to satisfy the transitioning requirements, the minimum number of plantings along this common boundary line shall be six trees for every 100 feet of adjacent property, including two each of evergreens, overstory trees, and ornamental trees. Credit for existing vegetation may be granted; however, a . more detailed inventory that identifies species, diameter, location, and condition, at a minimum, must be prepared and submitted to determine the extent of credit warranted for Lots 4-7. The proposed transition plantings on Lots 1-3 are sufficient for .those lots. Other considerations regarding the density transitioning plantings include: . Additional plantingsare necessary on Lots 8 & 9 Block 2. . An enlarged draV\IDg must be prepared that clearly indicates the quantities and species that will be installed/preserved on each lot. . Staff is recommending that density transition landscaping be installed (and accepted by City Staff) prior to the issuance of building permits for Block 2 . A 1\vo (2) year maintenance surety 'will be required to ensure the survival of the plants. -128- -
