The Water Infrastructure Finance Authority of Arizona is an independent entity authorized to finance the construction, rehabilitation and/or improvement of drinking water, waste water, waste water reclamation, and other water quality facilities/projects. As a “Bond Bank”, WIFA is authorized to issue water quality bonds on behalf of communities for basic water infrastructure. Generally, WIFA offers borrowers below market interest rates on loans for 100% of eligible project costs.

The Water Infrastructure Finance Authority of Arizona implements three types of technical assistance:
1. Project Technical Assistance – Planning and Design Assistance Grants assist an individual drinking water or wastewater system to conceive, plan, design, or develop an infrastructure project.
2. Policy Technical Assistance – Policy TA includes studies, surveys and other types of reports that provide benefit to a range of drinking water and wastewater systems statewide.
3. Operational Technical Assistance – The Arizona Department of Environmental Quality manages this program to provide assistance to individual drinking water and wastewater systems to improve facility operations.

The Drinking Water State Revolving Fund IUP describes WIFA’s plan to utilize various sources of funds to finance drinking water infrastructure and support related program activities during the State FY funding cycle from July 1 through June 30. This plan is a required element of the grant application documentation to obtain the grant award. Arizona herewith submits its IUP for the funds available to Arizona for the purposes of continuing the development, implementation and administration of the DWSRF program in Arizona.

The Intended Use Plan describes WIFA’s plan to utilize various sources of funds to finance clean water infrastructure and support related activities during the State FY funding cycle from July 1 through June 30. This plan is a required element of the grant application documentation to obtain the grant award for the purposes of continuing the development, implementation and administration of the Clean Water State Revolving Fund program in Arizona.

This open-file report describes the carbon-sequestration potential at the site of the 1 Alpine-Federal geothermal test drill hole, which is located south of Springerville in central eastern Arizona near the New Mexico border. A previous report, Arizona Geological Survey (AZGS) Open-File Report OFR 94-1, version 2.0, describes the subsurface geology encountered in the 1 Alpine-Federal well in much more detail than this new report.

The purpose of this research project is to determine the origin of the materials used to construct the Black Hills Dam in order to restore the landscape to pre-dam conditions. The Black Hills Dam site is located in northern Scottsdale, Maricopa County, at 33.75° North, 111.80° West. The goals of this project are to characterize the surficial deposits and local geology of the dam site. This report presents our findings, interpretations and conclusions based on background research, a site visit to the dam site, and technical discussions with the City of Scottsdale engineer and planners.

The goal of this study is to develop a method for identifying potential post-fire debris flow hazard areas prior to the occurrence of wildfires, providing more time for local governments and emergency planners to develop and execute hazard mitigation strategies. This pilot study focuses on the communities of Pine and Strawberry, which are located in forested canyons at the base of the Mogollon Rim in north-central Arizona. Results from this project will provide local agencies, emergency planners and land managers more effective tools for prioritizing watershed treatment areas and implementing mitigation measures to alleviate potential impacts and threats from post-fire debris flows to infrastructure, human life, and property in a timely and cost-effective manner.

In order to begin to assess debris‐flow hazards along the Santa Catalina Mountains in Pima County, we mapped the extent and character of relatively young prehistoric debris‐flow deposits in detail at fifteen
canyon mouths. Mapping was conducted on a scale of 1:6,000 using aerial photographs, detailed
topography, and field relationships. Deposits were classified into relative age categories based on
topographic relationships, soil development and surface characteristics of the deposits. Ages of selected
debris‐flow deposits in four canyons – Soldier, Sabino, Finger Rock and Pima – were estimated using
radiocarbon (14C) and cosmogenic (10Be) isotope methods.

Evidence of past debris flows were found in all fifteen canyons. Relative age dating, corroborated by
10Be, indicates the largest and most extensive deposits in all canyons are late Pleistocene to early
Holocene in age. Events from 2006 show that some potential exists for debris flows to exit the mountain front into developed areas near canyon mouths.

This field trip guide was created for a Project WET conference held in Tucson, Arizona, June, 2007. This guide discusses the general geology of the Santa Catalina Mountains in Sabino Canyon, and points out evidence of the July 2006 floods and debris flows. There are stops in the first few miles of canyon, and towards the end of the tram road, where the most spectacular debris flows are located.
