This study was developed to identify the resources and applicable methodology for the delineation of primary flood corridors.
Work maps for the Mission Wash floodplain. Highlighted photographs show the floodplain limits and watersheds.
The purpose of the Phase I study is to evaluate existing drainage conditions and to identify alternative flood control/floodplain management strategies which warrant further consideration.
This request for a Physical Map Revision is for a reach of Camino de Oeste Wash from Foret Road to Camino De Oeste Road. This PMR is to reflect improved topographical data available subsequent to the Flood Insurance Study of this area, and to establish base flood elevations for the floodplain.
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.
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.
This plan was undertaken by the Arizona Department of Transportation Multimodal Planning Division Aeronautics Group to evaluate and recommend a terminal area layout to meet anticipated terminal area demands.
Offsite drainage impacts the project site from several watersheds whose headwaters lie to the northeast of the project site. This report will address the manner in which the existing offsite and the post-development onsite drainage will be conveyed across this project.
