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.
This study documents the as-built condition and provides hydraulic support for a Letter of Map Revision application for the Camino Real Wash.
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.
Acquisition of this property in northeastern Pima County will prevent development of this property, conserve an important tributary to the San Pedro River, conserve riparian habitat associated with an intermittent stream and springs, and further goals of the Sonoran Desert Conservation Plan and Multi-Species Habitat Conservation Plan. The acquisition is ideally located to expand the emerging reserve system in the San Pedro watershed, which is anchored by the County's A7 Ranch, and complemented by the existing Buehman Canyon Preserve. This report provides preliminary biological and cultural information on this acquisition. Additional biological and cultural resource information will be available after County staff and consultants complete surveys of the property.
Without action by Pima County, Rosemont Ranch would probably either be mined or become a residential subdivision over the next several decades. A ranch conservation scenario offers the best outcome for preventing fragmentation of the landscape and conserving the natural and cultural heritage of the area.
