Full Breakdown
Chapter 15.32, adopted by Doc. 54/2012 effective June 26, 2012, establishes the floodplain district as "all special flood hazard areas within the City of Lawrence designated as zone A or AE" on the Essex County Flood Insurance Rate Map issued by FEMA, listing seven specific FIRM panel numbers dated July 3, 2012, and incorporating the accompanying Flood Insurance Study report by reference on file with the city engineer (§15.32.010). Section 15.32.020 requires a development permit before construction or development begins within zone A or A1-30, and directs the city to obtain and record the elevation of the lowest habitable floor of new or substantially improved structures, plus floodproofing certifications for floodproofed structures.
All development in the district, whether by right or special permit, must also comply with M.G.L. c. 131, §40, the relevant floodplain and coastal high hazard sections of the state building code (780 CMR), and three DEP regulations: the Wetlands Protection Regulations (310 CMR 10.00), Inland Wetlands Restriction (310 CMR 13.00), and Title 5 septic rules (310 CMR 15). The building commissioner keeps all floodplain records open for public inspection under §15.32.030. Within the floodway itself, §15.32.040(C) bars all encroachments, including fill and new construction, unless a registered professional engineer certifies no increase in flood levels during a 100-year flood event, and subdivision proposals must be designed to minimize flood damage and provide adequate drainage under §15.32.040(G).
Violations & Fines
The chapter itself sets no separate monetary fine; enforcement runs through the permit-denial power of the building commissioner, who administers the district and maintains the required floodplain records, with compliance tied to the underlying state building code and DEP regulations the chapter cross-references.
