Overview: The CSC is undertaking a
fourteen-month study to model flooding problems in the Sandy Run Watershed and prepare new floodplain maps for submission to
the Federal Emergency Management Agency (FEMA). Flooding problems have
seriously hampered economic development in the Fort Washington Office
Park and the Borough of Ambler of Montgomery County, PA. Unless these
problems are addressed and ameliorated, wise development of these areas
will continue to languish.

The study, funded by a $200,000 grant from FEMA, will include the
following outputs: hydrologic/hydraulic modeling and the preparation of
new floodplain maps for the watershed areas; two-foot digital contour
coverage for the watersheds and a Digital Elevation Map (DEM) based on
aerial photography flown in 2005; and an evaluation of existing
stormwater management facilities in the areas and field verification of
flood elevations and stream obstructions. There is a possibility to
extend the scope of this study by adding engineering evaluations of the
transportation and water and sewer systems in the watershed areas and
their impact on flooding. |
