Tybee Island Floodplain Management and CRS Program Assistance

Services Provided

GMC assisting the City of Tybee Island with a Repetitive Loss Area Analysis.  This analysis is a requirement for CRS communities with 50 or more properties that fall into the repetitive loss category as defined by FEMA.

GMC followed a five-step process which is detailed in the CRS manual to complete this report. The processing required GMC to delineate repetitive loss areas where flooding was likely to occur. To facilitate the competition of this task, GMC developed a mobile mapping application, which was utilized to perform field inspections of each property within the delineated areas. Once the inspections were completed, GMC examined the potential causes of flooding in these areas, what the City was currently doing to mitigate the problem, and other types of mitigation activities that could be considered. Full credit was awarded to the City for the Repetitive Loss Area Analysis report.

Maximizing Points in the CRS

GMC also assisted the City of Tybee Island with an audit of the Floodplain Management Program to allow the City maximizing points in the Community Rating System (CRS). The release of the 2013 updated CRS manual, which included the realignment of points within the different sections, raised concerns for city officials and staff that these changes could result in the movement from a Class 7 to a Class 8 in the program.

Assessment of Flood Damage

As part of the audit, GMC reviewed each activity in the CRS manual to determine where the City was currently receiving credit and where additional points could be captured. GMC completed a detailed assessment of the City’s Flood Damage Prevention Ordinance, and other development regulation, to determine their level of compliance with FEMA, the needed changes, and the number of CRS points that could be awarded for requirements that exceed minimum standards.  GMC also performed a detailed open space analysis, which allowed the city to maximize points available under this activity.

 

The project resulted in the City receiving a Class 5 score in the CRS program, which is an accomplishment that few cities in the State have achieved.
