It is unlawful to make any fill or deposit of rock, earth, sand, or other material, or any refuse matter of any kind or description, or build or commence the building of any wharf, pier, dolphin, boom, weir, breakwater, bulkhead, jetty, bridge, or other structure over, under, or within 40 feet of any navigable waters within the District without first submitting the plans, profiles, and specifications therefor, and any other data and information as may be required, to the District and receiving a permit therefor; and any person, corporation, company, municipality, or other agency, that does any of the things prohibited in this Section, without securing a permit, shall be guilty of a Class A misdemeanor. No permit shall be required in the case of any project for which a permit has been secured from a proper governmental agency before the creation of the District nor shall any permit be required in the case of any project to be undertaken by one or more municipalities located within the District for which a permit is required from a governmental agency other than the District before the municipality can proceed with the project. And in such event, one or more of the municipalities shall give at least 10 days' notice to the District of the application for a permit for any such project from a governmental agency other than the District so that the District may be present and represent its position relative to the application before the other governmental agency. Any structure, fill, or deposit erected or made in any of the public bodies of water within the District, in violation of the provisions of this Section, is a purpresture and may be abated as such at the expense of the person, corporation, company, municipality, or other agency responsible therefor, or if, in the discretion of the District, it is decided that the structure, fill, or deposit may remain, the District may fix such rule, regulation, requirement, restriction, or rental or require and compel any change, modification, or repair as shall be necessary to protect the interest of the District.
