H. Records For Public Inspection: The Village Engineer shall maintain for public inspection and furnish upon request base flood data, SFHA and designated floodway maps, copies of Federal or State permit documents, variance documentation, conditional letter of map revision, letter of map revision, letter of map amendment and as-built elevation and floodproofing and/or elevation certificates for all buildings constructed subject to this chapter.
I. State Permits: The Village Engineer shall ensure that construction authorization has been granted by IDNR/OWR for all development projects subject to sections 14-1-7 and 14-1-8 of this chapter, unless enforcement responsibility has been delegated to the Village.
