The 2009 Comprehensive Floodplain Management Plan and Program is intended to be used as a general guide for future decision-making in District activities. The Plan aims to present adequate background information to aid District staff in prioritizing areas for future studies and projects. The Plan identifies historic flooding events, reviews the District's efforts to solve flooding problems, and formulates five-year plans to reduce flooding through flood control project construction, floodplain identification, and planning programs throughout the county.

This memorandum describes (1) the potential applicability to Pima County of a national initiative to institute reforms in floodplain management; and (2) an assessment of the effectiveness of Pima County's Riparian Habitat Mitigation Ordinance (attachment).

To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers were prepared. In Pima County, ranching is uniquely able to preserve the integrity of vast tracts of connected and unfragmented open space and wildlife habitat. This study reviews the effect of five alternative permit strategies on the County's ability to preserve unfragmented landscapes through conserving ranch lands.
