This research study addresses the collection, preparation, and use of traffic data required for pavement design by the Arizona Department of Transportation, focusing on data required as inputs for the American Association of State Highway and Transportation Officials "Mechanistic-Empirical Pavement Design Guide" design procedures. ADOT’s current traffic data collection and preparation processes are not adequate to meet the needs of the MEPDG procedure, and improvements are needed. These improvements include enhanced volume, classification, and weight data collection for vehicles, processing data and performing quality assurance checks, and the preparation/analysis of the data for use in the MEPDG. Use of the MEPDG in Arizona will require (1) an annual flow of updated key traffic data and (2) the ability to collect on-site (MEPDG Level 1) data in a timely manner for key projects.
The Arizona Department of Transportation, in coordination with Apache County District II and the Fort Defiance Chapter of the Navajo Nation, analyzed the traffic circulation conditions of Navajo Routes 7, 12, 54, 110, and 112 within the Fort Defiance Industrial Area which is designated as a major growth area on the Navajo Nation. The study was funded by the Federal Highway Administration’s State Planning and Research Program and administered through ADOT’s Multimodal Planning Division's Planning Assistance for Rural Areas (PARA) program. The study was initiated to develop a planning strategy to improve the mobility and safety within the Fort Defiance Industrial Area.
The San Xavier District of the Tohono O’odham Nation is home to approximately 2,000 people. Numerous others come to the District to visit the San Xavier del Bac Mission Church. The San Xavier District Pedestrian Access and Safety Study is being prepared to improve the walking and bicycling environment on the San Xavier District for Community members and visitors alike. The study is being funded by the Arizona Department of Transportation Multimodal Planning Division’s Planning Assistance for Rural Areas program.
This Technical Data Notebook has been prepared in support of a Letter of Map Revision submittal to amend the 100-year floodplain, or Special Flood Hazard Area associated with Finger Rock Wash in Pima County, Arizona. The purpose of this LOMR application is to revise the effective Flood Insurance Rate Map SFHA boundaries based on updated and more detailed information. No new hydraulic structures are present within the study limits.
This report documents the existing drainage conditions related to Silverbell Trails Estates roadways and 100-year flow depths and includes qualitative and quantitative analyses of the existing hydrologic and hydraulic conditions.
The purpose of this study is to determine the hydrologic and hydraulic impacts of the Aspen Fire of the summer of 2003 on the Sabino Canyon and Carter Canyon watersheds, which are in the vicinity of the Town of Summerhaven, located on Mount Lemmon in the Santa Catalina Mountains, Arizona.
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.
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.
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.
