A majority of the work performed by ADEQ's Nonpoint Source Program is funded by Clean Water Act grants, awarded by the U.S. Environmental Protection Agency which requires States to report annually on progress in meeting the schedule of milestones contained in their nonpoint source management plans, and report reductions in nonpoint source pollutant loadings and improvement in water quality resulting from program implementation.

This circulation study has developed transportation improvements for all transportation modes including automobile, transit, bicycle, pedestrian, and equestrian transportation. Although bicycle and equestrian travel is not common on the East Reservation, projects were developed to encourage future use of these modes of travel. The plan recommends transportation improvements for 5, 10, and 20 year planning horizons

This study identifies a plan of improvements for vehicular, transit, and nonmotorized transportation and outlines the specific actions necessary to implement and sustain the plan. The recommendations for these elements are based on technical analyses of existing and future conditions as well as stakeholder and public input. The Study identifies projects that establish and improve multimodal options for Nation members. The development of these suggested projects includes consideration of evaluation criteria addressing such issues as safety and connection of multimodal transportation modes throughout the Nation and to the greater region. The Study projects will be included in the Nation’s Long-Range Transportation Plan, which provides the vision for meeting the community’s transportation needs over a 20-year planning horizon.

The purpose of this report is to present the data gathered to date in the Santa Cruz AMA in support of the management goal and groundwater modeling effort. This report presents groundwater and surface water monitoring data, USGS stream gaging data, effluent data, gravity studies, historical water use and water quality data for three distinctive stream reaches of the Santa Cruz River.

The purpose of the Verde Valley Multimodal Transportation Study is to develop a long-range regional transportation plan to guide the implementation of transportation improvements on the roads of regional significance in the Verde Valley, including I-17, State Routes, and roads on the County Regional Road System. This Study is an update of the 1999 Verde Valley Transportation Study Update.

The purpose of this project was to compile information on groundwater withdrawals and surface water diversions near perennial streams, intermittent streams, and shallow groundwater areas previously identified by PAG for the SDCP. The information could be used to prioritize future investigations of potential impacts of these withdrawals and diversions on riparian and aquatic habitats for the SDCP.

Pima Association of Governments updated a portion of the Water Usage Along Selected Streams in Pima County, Arizona, which PAG created in 2000. The updated report and datasets show current potential water usage in these critical areas. Deliverables include the shapefiles, spreadsheets and maps that accompany this memorandum. The purpose of this report is to provide updated information about the location and pumping history of wells located in Pima County near shallow groundwater areas, generally located near drainages.
