  • Successful implementation of the Skunk Creek Watercourse Master Plan was largely dependent upon prudent watershed management in the Adobe Dam / Desert Hills ADMP study area.
  • The piecemeal development in the area, without the benefit of master planning, resulted in significant alternations to runoff characteristics and drainage patterns in the watershed.
  • There was a need to preserve and/or provide watercourse capacity to convey future condition flows in Skunk Creek, the axial watercourse in the study area.


  • JEF applied state-of-the-art methodologies in inventorying existing watershed conditions and in analyzing existing and future hydrologic, hydraulic, and geomorphologic conditions.
  • JEF involved residents and coordinated with agency stakeholders throughout the development of the area drainage master plan to facilitate successful implementation.


  • JEF recommended a drainage master plan comprised of structural and non-structural solutions to address identified problems and build a consensus-based solution for multiple objectives.
  • JEF developed regulatory tools for use by agencies to manage future development and prepared a prioritized, risk-based assessment of existing residential structures located in the floodplain.
  • JEF prepared a watershed-wide flood response plan to provide flood warning to residents and to identify action protocols for use by emergency responders during flood events.
