Aldridge Creek Watershed Stormwater Management Plan Survey and Flood Elevation Certificates, Huntsville, AL

J&A was teamed up with AMEC to conduct a Stormwater Management Master Plan for the 21 square mile Aldridge Creek watershed in southeast Huntsville, Alabama. J&A surveyed stream cross sections at 100-foot intervals for 30 miles of the main channel and 17 main tributaries.  We also inventoried hundreds of storm structures within the basin, and  located, documented, sized and measured all bridges, culverts and pipes along the main channel and  tributaries. Additionally, J&A surveyed and prepared approx. 1100 flood elevation certificates of all building structures within or near the current floodplain for use by the City and homeowners for flood insurance purposes.
