The objectives of this report are to document the on-site and off-site hydrologic and hydraulic assessment of the site and its characteristics, quantifying existing conditions peak discharges, and define the limits of 100-year on-site floodplains.
This parcel has some houses already constructed, but most of the area is left undeveloped and can be classified as desert foothills. The objective of this report is to determine all of the flows generated by a 100-year storm in excess of 100 cfs and then map the flood-prone boundaries for the associated channels.
Tucson Water's Valley View Reservoir site and Flecha Caida Ranch Estates #9 has experienced numerous drainage-related problems,including inundation, erosion, and limited access during the rainy season. A portion of the reservoir site and approximately one-half of the subdivision are both located in the 100-year flood plain.
This report is being submitted for the purpose of reducing the erosion setback limits. The information contained herein supports the claim that a safe reduction in the setback distance can occur.
