Montgomery County Model Floodplain Ordinance

FEMA categorizes municipalities into four levels, depending on the data depicted on the Flood Insurance Rate Maps (FIRMs). There are four versions of the county’s model floodplain ordinance, which correspond to the municipal levels determined by FEMA. Click here to find your municipality's floodplain ordinance (you'll find a list of municipalities with links to their version of the model ordinance). Please note that the model ordinance has been revised recently to address changes in the DCED suggested provisions. These changes appear in red in the model ordinance.

Municipalities participating in the National Flood Insurance Program (NFIP) must maintain a floodplain ordinance. The PA Department of Community and Economic Development (DCED) published suggested provisions that need to be included in an ordinance to comply with FEMA’s requirements. According to the DCED, the suggested provisions are not a model floodplain ordinance but were prepared to meet only the minimum requirements of the NFIP and the Pennsylvania Flood Plain Management Act. The DCED indicates that considerably more could be done concerning the regulation of development in flood-prone areas for interested municipalities.

Montgomery County recognizes that many existing municipal floodplain ordinances currently offer a high level of protection, above that of the DCED suggested provisions. For municipalities that may want to continue with this level of protection, and for those which want to bring their floodplain regulations up to this higher level, the county has developed a model floodplain ordinance.

FEMA Supported Municipal Meetings

The Montgomery County Planning Commission, with the support of FEMA Region III, held a municipal meeting on the new Flood Insurance Rate Maps and municipal floodplain ordinance requirements. The meeting focused on actions the municipalities need to take to stay in good standing in the National Flood Insurance Program. Information on the new flood maps, the ordinance adoption process, the NFIP, FEMA’s Community Rating System, and the Schuylkill Watershed Project was discussed. The meeting agenda, presentations, and handouts are below:
