The year 2002 marked the largest outbreak to date in the world as the virus rapidly spread across the U.S. Maricopa County has been spared the burden of widespread WNV-illness thus far, however the area is home to a viable mosquito population, many species of migratory birds and a large human populace with a propensity for outdoor activities making arrival of the virus inevitable and advanced preparations invaluable.

The “Rural Planning Area” concept is a means by which traditional agricultural enterprises such as ranching can be preserved in the face of changing economic conditions. The intent of the Diablo Canyon Rural Planning Area is to identify a range of economic opportunities that would be compatible with maintaining traditional ranch operations on the Flying M and Bar T Bar. To be sure, some of the options identified in this plan are very different from traditional ranch practices, but they are intended to help support the existing ranches economically while keeping the ranches intact and operating into the next generation and beyond.

The purpose of the Valle Area Plan is to ensure that future development in the area is in the interest of public health, safety, and welfare, that it is not detrimental to the established character of the community, and that it preserves or enhances the special characteristics that define the Valle Area. More specifically, the plan serves as an amendment to the Coconino County Comprehensive Plan, and guides the decision-making processes of the Planning and Zoning Commission and Board of Supervisors in their consideration of zone changes, subdivisions, conditional use permits, and other development-related proposals.

As the principal gateway to the Grand Canyon, the community of Tusayan plays an important role in the provision of goods, services, and information to tourists and visitors. The study area extends three miles north to the Grand Canyon National Park boundary, and four miles south of the existing community and five miles on either side of Highway 64. The plan has no established time period. The last Tusayan plan, the South Grand Canyon Specific Area Study, was adopted by the Board in 1978. Ideally, this plan will be updated and amended regularly.

The Red Lake Study area consists of almost 40,000 acres of private land within an approximately 150 square mile area. State of Arizona and National Forest Service land comprise the remainder of property in the study area. The area extends north 14 miles from the Williams City Limits. Highway 64 bisects the study area with the boundaries extending 5 to 6 miles to the east and west. The study area is bounded on the east by the center line of Range 3 East, to the north is the 6th Standard Parallel, the west boundary is an extension of the west section line of Section 2, T24N, R1E, and the Williams City Limits forms the southern boundary. Land uses in the study area have evolved slowly through the years. The primary land use has historically been ranching. Most of the subdivisions were platted during the height of land speculation in Arizona in the 1960's and early 70's. The commercial development in the study area was primarily established in order to serve tourists traveling to the Grand Canyon.

The purpose of the "Parks Area Plan" is to ensure that future development in the area is in the interest of the public health, safety, and welfare, that it is not detrimental to the established character of the community as a whole, as well as individual neighborhoods, and that it preserves or enhances the special characteristics that define the study area. The plan is adopted as an amendment to the "Coconino County Comprehensive Plan", and guides the decision-making processes of the Planning and Zoning Commission and Board of Supervisors. The plan does not identify specific land uses for specific locations, but sets forth goals and policies designed to protect the special characteristics of the community, while allowing for orderly, well-planned, and appropriate development. The plan has no fixed time period, but is intended to be applicable for approximately ten years.

The main purpose of this study is to evaluate the existing land use and ownership patterns, identify the major environmental characteristics and propose policies for adoption by the Planning and Zoning Commission and the Board of Supervisors that will serve as a guide for future development within Oak Creek Canyon from Pumphouse Wash to Midgely Bridge. Formal planning for the area originated in 1976. The "Sedona Community Plan" was subsequently adopted by Coconino County in late 1979 and has since served as the guide to future land use determinations for that portion of the Sedona community located within Coconino County.
