These activities <br />include, but are not limited to, building or enlarging a structure, remodeling or <br />improving a structure, placing a manufactured home, mining, dredging, filling, <br />grading, paving, excavating, and drilling within the 100-year flood hazard areas. In <br />other words, any structural or non-structural activity that may affect flooding or flood <br />damage must have a permit. <br /> <br />A Floodplain Development Permit from the local Floodplain Administrator is required <br />before beginning any construction and development activities within a 1 OO-year flood <br />hazard area. <br /> <br />1.8.1 INITIAL FLOODPLAIN DETERMINATION <br /> <br />Prior to the submittal of a building/grading permit <br />or a development application, an initial floodplain <br />determination for the proposed project site must <br />be issued by the local Floodplain Administrator <br />(Standard Form CH4-SF101). The Floodplain <br />Administrator will determine whether the <br />proposed project site is located within the 100- <br />year flood hazard area shown on the community's <br />floodplain map and/or FEMA FIRMs. <br /> <br />A Floodplain Development Permit will be required <br />before a building or grading permit can be issued <br />for any construction and development activities <br />within the 10Q.-year flood hazard area. The initial <br />floodplain determination may also identify other <br />special provisions that may be imposed as a <br />condition of approval for a Floodplain <br />Development Permit. <br /> <br />The initial determination will identify only minimum <br />requirements. This determination is intended only <br />to guide the applicant and the community in its <br />application of the Floodplain Management <br />Regulations. Additional require-ments may be <br />imposed during the project or permitting review <br />process as additional technical information is <br />presented or project modifications are made. <br />Property owners, who wish to obtain a more <br />detailed floodplain determination than can be <br />provided from the existing data, must obtain their <br />own determination from licensed and qualified <br /> <br />AUGUST 2002 FLOODPLAIN <br />MANAGEMENT <br /> <br />Prior to the <br />submittal of a <br />building/grading <br />permit or a <br />development <br />application, an <br />initial floodplain <br />determination for <br />the proposed <br />project site must <br />be issued by the <br />local Floodplain <br />Administrator. A <br />Floodplain <br />Development <br />Permit will be <br />required before a <br />building or grading <br />permit can be <br />issued for any <br />construction and <br />development <br />activities within the <br />tOO-year flood <br />hazard area. <br /> <br />CH4-107 <br />
