Review File: Village Bank Major Plat Preliminary Plat Request Page 2 of 3 Topsoil: The newly created lots will need to have four (4) inches of topsoil meeting the City's topsoil specification across all disturbed areas not otherwise improved with walkways, driveway, and home. A topsoil inspection is required prior to landscaping being installed and copies of the load tickets are required as well. This is reviewed at time of Building Permit Application and request for Certificate of Occupancy for the newly created lots. Note: any wetlands within the limits of construction will need to be delineated and marked so that the wetland boundary is evident. The flood fringeffloodway boundary will also need to be identified/marked. No topsoil or other fill is permitted within any wetland or within the floodway. Floodplain: Portions of the property are within a designated floodplain, which includes both flood fringe and floodway designations. No fill can be placed within the floodway portion of the floodplain without first obtaining a Conditional Use Permit (and must be demonstrated that it will not cause any increase in the stage of the 100-year flood). Placing more than 1,000 cubic yards of fill (cumulatively) within the flood fringe would also require a Conditional Use Permit. The floodplain shall be clearly identified on the Preliminary Plat submittal and should distinguish between the floodway and flood .fringe areas. The following additional comments are offered: • The submittal information shall include scaled plans that identify the following in relation to watercourse channel: o Location, dimensions and elevations of each lot o Proposed structures *Approximate Boundaries *Blue line = Floodway *Purple area = floodplain o Areas of fill (and specific quantities) • The lowest floor elevation of all structures shall be at or above the Regulatory Flood Protection Elevation (RFPE), which is, at a minimum, one (1) foot above the Base Flood Elevation (BFE) plus any increases in flood elevation caused by encroachments on the floodplain that result from designation of a floodway (847.5 ft). • If fill will be used within the flood fringe area to elevate building pads to or above the RFPE, this will require a Letter of Map Change (LOMC) from the Federal Emergency Management Agency (FEMA). The Applicant shall provide evidence of receipt of the LOMC prior action on the Final Plat. • For the portions of property within the flood fringe area, fill shall be properly compacted and the slopes shall be properly protected by the use of rip -rap, vegetative cover or other acceptable method. FEMA has established criteria for removing the special flood hazard area designation for certain structures properly elevated on fill above the 100-year flood elevation, FEMA's requirements incorporate specific fill compaction and side slope protection standards for multi -structure or multi -lot developments. These standards should be investigated prior to the initiation of site preparation if a change of special flood hazard area designation will be requested. • All new principal structures must have vehicular access at or above an elevation not more than two (2) feet below the RFPE.
