The objective of this Technical Data Notebook is to provide 100-yr peak discharges at Concentration Points for the Unnamed Wash 12, 100-yr floodplain boundary and erosion hazard information, using the most up-to-date topographic, hydrologic, and hydraulic data.
This report was prepared to document surface water hydrology and floodplain conditions in accordance with current standards of practice. This information is intended to support issuance of building permits, re-approval of construction drawings to current standards, and issuance of floodplain use permits, if needed.
Originally, the purpose of the study was to obtain either a Letter of Map Revision or a Physical Map Revision from the Federal Emergency Management Agency. Unfortunately, during the initial stages of the investigation, it became apparent that FEMA's guidelines for these types of map revisions could not be accommodated, primarily due to flow-distribution conflicts.
Historically, Pima County has recorded several residential concerns, detailing this area as a reach of wash with severe flooding problems. The purpose of this report is to present the engineering analyses of four alternative remedial flood-control measures.
This study documents the as-built condition and provides hydraulic support for a Letter of Map Revision application for the Camino Real Wash.
