-5- 4.2 BUILDING SITE IMPROVEMENTS 4.21 No subdivision or part thereof shall be approved i£ proposed sub- division development in a floodway will, individually or collectively, significantly increase flood flows, heights, or damages. 4.22 No subdivision or part thereo£ shall be approved for floodway or floodway fringe areas which will substantially af£ect the storage capacity of the flood plain. 4.23 Building sites, residences, motels, resorts and similar uses for human occupation shall not be permitted in £loodway areas. Sites for these uses may be permitted outside the floodway if the sites are elevated to a height. at least one (1) foot above the elevation of the regional flood or provisions otherwise made for elevating or adapting structures to achieve the same result. Required fill areas must extend fifteen feet beyond the limits of intended structures and, if the subdivision is not to be sewered, must include areas £or waste disposal. 4.24 Building si:tes £or structures other than residences outside of flood- way areas shall ordinarily be £illed as provided in 4.23. However, the Board of Appeals may allow subdivisions of areas for commercial and industrial use at a lower elevation if the subdivider agrees to protect the uses through structural flood-proofing as specified (Section 5.4.) 4.25 Wlhen the planning agency determines thatonly part of.a proposed plat can be safely developed, it shall limit development to that part and shall require that the method of development is consistent with its determination. 4.26 l-]hen the subdivider does not intend to develop the plat himself, and the planning agency determines that limitations are required to insure sa£e development, it may require the subdivider to impose appropriate deed restrictions on the land. Such deed restrictions shall be inserted in every deed and noted on the face of the final recorded plat. 4.3 DRAINAGE FACILITIES Storm drainage facilities shall be designed to convey the flow of sur£ace waters without damage to persons or property. The system shall insure drainage at all points along streets, and provide positive drainage away £rom buildings and onsite waste disposal sites. Plans shall be subject to the approval of the Board of Appeals. The agency may require a primarily underground system to accommodate frequent floods and a secondary surface system to accommodate larger, less frequent £loods. Drainage plans shall be consistent'with local and regional drainage plans. The £acilities shall be designed to prevent the discharge o£ excess runoff onto the adjacent properties. 4.4 ROADS The finished elevation o£ proposed streets shall be no more than (1) faot below the regional £lood. The Board of Appeals may require, where necessary, profiles and elevations of streets to determine compliance with this requirement. Drainage openings sha11 be sufficient to discharge flood flows without unduly increasing flood heights.
