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.
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.
This report is intended to revise the previous watershed hydrologic and hydraulic calculations for the proposed extension of Camino Del Sol Road. This study is necessary because of significant land use changes within the watershed.
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.
The purpose of this study is to define the scope of the problem and to recommend alternative approaches which would reduce the flood damage potential associated with future private driveway access across the watercourses and to provide more hydrologic and hydraulic information.
This plan has focused on two program areas: 1) floodplain management through revised floodplain delineations and assessment of subsequent FEMA mapping revisions; and 2) basin-wide planning issues involving both short- and long-term drainage infrastructure and regulatory needs.
The purpose of this study is to (1) develop a fundamental understanding of the problems that exist, and (2) perform a cursory examination of possible management approaches identifying those that appear most plausible for further consideration.
This report describes the hydrologic and hydraulic analysis. Development in the lower end of the watershed has occurred without knowledge of the floodplain's characteristics.
