3¥~.ri~old Pond l;'inal l~lal Review ..&!y 22, 2005 num b~r o1' young spruce and pines will be transplanted from this site to other areas within the site as well as to Ehncrest Park. During construction of individual homes, all effo~s should be made to preserve individual trees wherever feasible. Tree save fen.cing is required around all trees or groups of trees to be preserved. The fencing shall include, at a minimum, the entire area beneath the tree canopy, which is known as the critical root zone. No construction activity whatsoever may occur within these areas. Moreover, no construction shall begin until this fencing has been installed and approved by the City. Filmily, due to the number of oak trees on and adjacent to the development area, a plan must be submitted outlining the actions that will be taken to protect those trees from oak wilt. Any clearing involving oak trees cannot occur between April 15 and July 15 to help protect against oak wi lt. l)ue to some revisions that are necessary to the grading plan near the Highway 47 underpass, a revised tree preservation/landscaping plan should be submitted for this area. Density Transition: Through a combination of existing vegetation, new plantings, and the ex/sting wetland area on the eastern portion of the site, density transition requirements are satisfied R>r the site. Wetlands: A substantial portion of the property is wetland. These wetland areas have been delineated by Kjolhaug Environmental Services which has been verified by the LLRWMO. Sheet I'A of thc submittals propose a 10-foot wetland buffer along all the wetlands in the plat. The plat will fill 4,221 square feet of wetland (0.1 acres) to construct Iodine Street which has been approved as a deminimus exemption under the LRRWMO permitting process ~l'he City is in the process of creating a wetland buffer ordinance that will require vegetative buffer strips around all wetlands within a development. A ten (10) foot wide wetland buffer strip has been voluntarily proposed around all wetlands within this site. It is unclear whether the buffer strips will be planted or if there is existing vegetation that is sufficient. Either way, the City is requesting that wetland buffer monumentation be installed along the edge of the buffer strips at a spacing not to exceed 200 feet and that at least one such monument is installed per lot. Location and specifications for the monuments should be reviewed with City Staff. Silt fencing should be installed along the edge of the wetland buffer. (;radi,g and Drainage Plans: A final grading and drainage plan dated 5/12/05, has been prepared for this subdivision by Mark Kretctuner PE. Staff offers the following comments on this I. Elevations and cross sections need to be provided to insure that the trail can be constructed as proposed on the grading plan. ~l'he maximum slope permitted is 4 feet horizontal to 1 foot vertical. Some of the steep slopes, particularly the berms, exceed this standard.
