The City of Chandler developed the South Arizona Avenue Entry Corridor Study in 2006, setting forth a vision for the development of the corridor between Dr. A.J. Chandler Park and the new SanTan Freeway, ¾ mile to the south. Between downtown and the freeway is the corridor that the City intends to see redeveloped, with mixed residential and commercial uses to create a dynamic new “front door” for Chandler. The purpose of these design guidelines is to guide zoning requests within the South Arizona Avenue Corridor to achieve the objectives of the Chandler General Plan. The overall goal of these objectives is to implement the vision for South Arizona Avenue. The guidelines address the major design aspects of new office, retail and residential buildings in the corridor. Design Guidelines are not building or streetscape designs; they provide design direction so that each project’s architectural design will reinforce the City’s strategic intentions as this important area of the city responds to its new role as Chandler’s “front door.” These guidelines also identify streetscape design principles for South Arizona Avenue with the objective of coordinating public and private design in the Corridor.
The Chandler Airpark area encompasses nine square miles surrounding the Chandler Municipal Airport. The area plan provides the City of Chandler with a document that will strategically guide future development in and around the existing airport. The two major goals of this plan are the protection of the Municipal Airport from residential encroachment and the aggressive economic development of the Airpark area.
This Additional Site Characterization Work Plan presents a strategy for collecting site characterization information at the closed Maricopa County Cave Creek Landfill to support ongoing remedial action planning for trichloroethene-impacted groundwater underlying the site. The Work Plan supplements previous remedial investigation work plans prepared to characterize the nature and extent of site contamination.
This document has been prepared to fulfill the requirements for a hydraulic study for the Cave Creek Landfill operated by Maricopa County.
During the period of 1965 through 1984, Maricopa County operated a landfill leased from the U.S. Bureau of Land Management. In 1982 the County leased a separate parcel from the State for the development of a new landfill. The landfill stopped accepting waste in 1998.
To evaluate whether VOCs are migrating out of the landfills into the vadose zone, a soil vapor survey of the soil beneath the landfill bases was performed. Permanent vapor monitoring probes were installed and then sampled twice for VOCs. Groundwater beneath the landfills has been impactd by VOCs, namely TCE, DCE, and toluene.
An update to the 1998 Chandler Municipal Airport master plan to make it meet current Federal Aviation Administration and Arizona Department of Transportation requirements as well as anticipated needs of Chandler residents and businesses.
This study involved the review of 417 ADEQ LUST site files and compilation of relevant data from 323 of these sites into an electronic database. It also involved the collection and analysis of over 700 supplemental groundwater samples, the assessment of aquifer flow properties from 32 wells at 11 sites, and more detailed characterization at six LUST sites representative of a range of conditions at AZ LUST facilities. In addition, over 300 groundwater level measurements were performed and 175 monitoring wells were re-surveyed in order to assess errors in standard practice and their impact on groundwater flow direction determination. An empirical analysis of groundwater impacts at AZ LUST sites was conducted using these data sets, with emphasis on identifying relationships between site conditions (e.g., geology, depth-to-groundwater, etc.) and groundwater impacts. Finally, a combined theoretical-spatial (GIS) analysis was performed to identify LUST scenarios posing the greatest threats to use of groundwater resources.
This addendum to the 2005 work plan identifies how additional assessment of groundwater features and contamination at Cave Creek Landfill will be conducted.
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.
