SE-08-45 TEP Cienega Substation - Colossal Cave Road
Special Exception RH
Rincon Southeast Subregional Plan, Map Detail #8
10/28/08 drcorral IPC

This special exception request is to allow a Tucson Electric Power (TEP) electrical substation to be located on a 12.7-acre, right-of-way (ROW) portion of a 308.15-acre Arizona State Land Department (ASLD) parcel. The TEP site is located north of Interstate 10, west of Colossal Road, on the north side of Dawn Road. The site is zoned RH and is surrounded by RH on all sides. Vail Vista Estates and New Dawn Estates are located to the east of Colossal Cave Road.

Land Use Plan Policy Summary

Land use plan policy guidance is provided by the Rincon Southeast Subregional Plan (RSSP) Map Detail #8 and the City's General Plan. The Design Guidelines Manual suggests design techniques that can be used to implement land use plan policy objectives.

The Houghton/Dawn map detail covers an approximately 3,500-acre or 5.5-square-mile area of undeveloped State Trust lands, generally located north and south of Interstate 10 between Houghton Road on the west and Colossal Cave Road on the east. The terrain is generally flat and braided by a network of shallow washes. The characteristic vegetation is creosote, bur sage, and cacti species, with mesquite found in and along the washes.

The area is zoned RH (Rural Homestead, very low-density residential) and RX-1 (low-density residential). Both high voltage transmission lines and an underground gas pipeline affect the area. The area is planned Development Reserve. Development Reserve is a "holding zone" for future urban development; rather, Development Reserve designates areas for future urban land uses. As such, the proposed utility substation is an allowed use, as it sets the stage for future urban land uses in the area.

The Environmental Resource Zone (ERZ) recognizes the value of Tucson's open space resources, particularly the critical and sensitive wildlife habitat of eastern Pima County associated with public preserves. The Houghton/Dawn area contains numerous significant washes that were added to the ERZ base map when original City zoning was established for this area. The proposed substation will not impact any existing ERZ watercourses.

General Plan policy supports measures that protect life and property, including those that minimize potential loss due to flooding and erosion. Policies promote protecting washes and associated habitat and wildlife corridors. Other policies encourage environmentally sensitive site design that enhances the visual quality of the community and, the Design Guidelines Manual suggests techniques for improving the visual appeal of freestanding walls, and screening less visually attractive uses, such as utility equipment.

Discussion

TEP staff and their consultants attended a rezoning presubmittal meeting on June 25, 2008 and held a neighborhood meeting on August 26, 2008. Approximately 10 neighborhood residents attended. Concerns raised during the meeting included installation of underground distribution facilities (feeders) on ASLD land adjacent to the west boundary of New Dawn Estates, the color of the poles and security around the substation.

Sufficient information has been provided to demonstrate that the proposal is in substantial compliance with the RSSP and the General Plan. A plan amendment is not required. Upon full review, staff will focus on site design aspects intended to minimize impacts of the site on the surrounding areas.

Recommendation

Staff recommends that this application be accepted for further processing.



ADOPTED PLAN POLICY


HOUGHTON/DAWN MAP DETAIL #8-RSSP

Plan Adoption Date: June 10, 1996 (Resolution No. 17293)
Annexation Date: January 2, 1996 (Ordinance No. 8616, C15-95-19)

General Description

The Houghton/Dawn map detail covers an approximately 3,500-acre or 5.5-square-mile area of undeveloped State Trust lands, generally located north and south of Interstate 10 between Houghton Road on the west and Colossal Cave Road on the east. This map detail area lies immediately east of map detail #4-RSSP and shares many of the same environmental characteristics. The terrain is generally flat and braided by a network of shallow washes. The characteristic vegetation is creosote, bur sage, and cacti species, with mesquite found in and along the washes.

The area is zoned RH (Rural Homestead, very low-density residential) and RX-1 (low-density residential). The closest residential development is a recreational vehicle park located east of Houghton Road, just north of the Rocket Road alignment. Both high voltage transmission lines and an underground gas pipeline affect the area.

The Major Streets and Routes Plan (MS&R) identifies certain streets for special designation as scenic or gateway routes. Because Houghton Road north of the Harrison-I-10 area had previously been designated a gateway route, this gateway designation was extended south at the time original City zoning was established for this area. In addition, Colossal Cave Road is designated as a scenic route in the county and is a candidate scenic route in city. This is the first segment of Colossal Cave Road to be annexed into the City.

The Environmental Resource Zone (ERZ) recognizes the value of Tucson's open space resources, particularly the critical and sensitive wildlife habitat of eastern Pima County associated with public preserves. The Houghton/Dawn area contains numerous significant washes that were added to the ERZ base map when original City zoning was established for this area.

In addition to the environmental concerns regarding wash preservation, the most significant influence on future development is Interstate 10, which diagonally bisects the area. The Southern Pacific Railroad, immediately north of the plan area, will also impact future land uses and transportation both within the plan area and in adjacent undeveloped areas to the north. Because the area is undeveloped, there is little infrastructure. The I-10 interchange for Colossal Cave Road/Wentworth Road lies directly south of the easternmost portion of the plan area. Colossal Cave Road leads to the community of Vail and the Rincon Valley. Wentworth Road leads south to New Tucson.

The Eastern Pima County Trail System Master Plan shows the Flato-Franco washes (#4) as a Second Priority Primary Trail. This trail route is comprised of natural washes and road and utility rights-of-way. In the Houghton/Dawn area, the trail follows the underground gas line easement and Colossal Cave Road and is primarily intended to serve as a long distance equestrian trail and desert belt connection to Cienega Creek.

Plan Designations

Areas identified as ERZ washes are designated Resource Conservation (RC) on the map detail. Otherwise, plan designations generally reflect current zoning. The area south of the interstate is planned Low Intensity Rural and Medium Intensity Rural, which generally correspond to RH and RX-1 zoning. The majority of the area north of the interstate, zoned RH, is planned Development Reserve. Development Reserve is a "holding zone" for future urban development. The Medium Intensity Rural designation north of the interstate reflects RX-1 zoning. The I-10 corridor is planned Medium High Intensity Urban and restricted to nonresidential uses by Special Area Policy 5-03. Design standards in this corridor are provided by Special Area Policy 2-03.

Applicable Subregional Policies

All Subregional Policies should be reviewed for applicability to land use proposals within this area. Depending on the particular site under consideration and the nature of the rezoning request, Natural and Cultural Resources policies, particularly Open Space, Wildlife Habitat, Regional Trail System, and Archaeological and Historic Preservation policies, will be particularly important to guide development in this area.
