Title
Consider and take action on an ordinance amending "Chapter 50 of the Code of Ordinances of the City of League City entitled, “Floods” regarding engineering standards for the minimization of flood losses (Executive Director of Development Services)
Background:
Approval of this item will amend Chapter 50 of the Code of Ordinances of the City of League City. This “Flood Ordinance” contains requirements for sub-dividers, developers, applicants, engineers, surveyors, realtors and other persons interested and involved in the subdivision and development of land within areas of the FEMA recognized special flood hazard areas (100-yr floodplain) and within the Zone X (shaded) areas (500-yr floodplain).
