Description

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.

DescriptionA follow-up report that includes a copy of a USGS quadrangle map, an aerial photograph of the drainage basin, and documentation addressing the 1-hour, 100-year rainfall amount.
Created1996 to 2006
Description

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.

Description

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,

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.

Description

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.

Description

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.

Description

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.

Description

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

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.

Description

Phase IIA focuses on identifying alternatives for mitigating the hazards and problems, evaluating the alternatives for flood mitigation potential and cost effectiveness, and recommending a preferred alternative and flood control policy.

Description

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.
