considered premature, is consistent with the original PUD and meets the performance standards of the subdivision and zoning ordinance. Blocks and Lots The preliminary plat amendment creates 5 blocks with 32 lots and 3 Outlots and will be final platted as Century Farm North 61h Addition. Outlot A and B protect wetlands and ACD 10-22 drainage ditch corridors. Outlot C is proposed for future townhome development and shall require final plat. Typical lots are shown as 62 feet wide and 130 feet deep. Streets and Alleys Robinson Drive is classified as a minor collector roadway and shall be constructed in its entirety the full length from CR 53 (Sunset Avenue) to Century Trail (approximately 1,600 feet) with this next phase of development. CR 53 (Sunset Avenue) is currently classified as a major collector and 60 feet right of way from centerline is being dedicated as required. Trail and/or sidewalk shall be constructed along Robinson Drive. Easements Standard drainage and utility easements are shown around the interior perimeter of lots and around wetlands and storm water ponding areas. Per Rule C.IO(d), projects within CWPMP areas, the wetland management corridor (WMC) boundary delineation, buffer and easement requirements found at Rule F.6 apply. This may require more than the 10 foot buffer shown around the wetlands. Storm Water Management and Erosion and Sediment Control A Stormwater Drainage Report was prepared by Plowe Engineering, Inc. on March 10, 2014. The existing site was partially graded as part of a previous phase. Robinson Drive was graded along an assumed alignment to avoid the Morell parcel and connect to Sunset Road. A pond was also excavated adjacent to the public ditch. The eastern half of the site drains to an existing pond constructed in a prior phase. The remainder of the site generally slopes to an existing ditch (ACD 10-22-32 Branch 1) that runs north/south through the approximate mid -point of the parcel, and an existing pond adjacent to the ditch. Drainage patterns will remain generally unchanged from what previously proposed with the 5th Addition rough grading. However, due to changes in RCWD, rear yards will be collected and routed to ponding areas. Infiltration has been deemed infeasible due to: (a) Presence of seasonally high water tables in several of the on -site borings. The 3-foot separation to water table cannot be achieved. 7
