Maintaining On-site Stormwater Retention All properties are required to contain stormwater runoff on-site consistent with stormwater standards. Affecting this on-site drainage, either through placement of fill or regrading of a property, requires review by the City. • Any alterations in grade will require an engineered drainage plan and drainage certification letter from engineer after completion. • Restoration work to restore grades based on an existing approved drainage plan, a drainage certification letter from the engineer will be required after completion. Approved drainage plan must be included in permit application. • Addition of fill (other than to restore a property to an existing approved drainage plan) requires approval of a development permit. The placement of fill on a property that alters the existing drainage pattern, ground contours, or grade elevations of the real property or the bottom elevation of an open body or water, constitutes development (Section 78-9) and a development permit is required. • Detailed standards for Stormwater control can be found in Chapter 118, Article IV of the Land Development Code. Sanitary Sewer The City of Sanibel is the provider of wastewater (sewer) for residents. • If you are demolishing your existing house, please be aware that the sewer connection must be disconnected and capped off, and you or your contractor must request an inspection from Public Works to verify that the disconnection point was appropriately sealed off. • All nonresidential properties are required to submit a wastewater availability agreement to verify if there is any expansion or change of use. Fees will be required for additional Equivalent Residential Credits (ERC) not included in previously approved uses of the property. • Standards for Wastewater disposal can be found in Chapter 118, Article III of the Land Development Code. If you have any questions on the above, please contact the Public Works Department at sanpw@mysanibel.com or (239) 472-6397.
