SE-15-66 IPC TEP - Harrison Road

Plan Tucson and Pantano East Area Plan
09/01/15 MP

Background: This proposal is for a special exception use in the C-1 commercial zone to allow a Tucson Electric Power (T.E.P.) Substation on a 5.89-acre site. The proposed T.E.P. Substation power line transmission will connect to existing T.E.P. transmission power line structures located on Speedway Boulevard along the south right-of-way boundary. T.E.P. infrastructure and equipment will be within a 180 X 350 square foot area that will enclosed by a ten (10) foot tall masonry wall. Substation enclosed area will be approximately twenty (20) feet from the north property line and approximately one-hundred and forty (140) feet from the west property line. On-site T.E.P. Substation infrastructure improvements to be located outside of the wall enclosure include an 83 foot tall transmission structure and a 90 foot tall transmission drop in structure. Within the wall enclosure there will be six (6) lighting poles with a height of sixty (60) feet and one communication T.E.P. communication pole at a height of seventy (70) feet. Additional site improvements include a twenty (20) foot wide landscape buffer along the west and north property lines and a ten (10) foot wide landscape buffer along Speedway Boulevard and Harrison Road street frontage. A retention/detention basin is proposed along the west one third of the site that incorporates the Jasmine Wash and allows the wash to enter and exit the site at its natural points, which flows from south to north. Access is proposed from both Speedway Boulevard and Harrison Road. The nearest single-family residential home is located to the north approximately 30 feet from the proposed utility substation site


According to the Major Streets and Routes Plan, Speedway Boulevard and Harrison Road are both designated arterial streets.

Surrounding Zoning and Land Uses: The proposed special exception (T.E.P. Substation) site is a vacant parcel with 5.89-acres and zoned C-1 commercial. To the north and west is developed with Hidden Hills East, a residential subdivision with detached single-family homes in the R-1 low density residential zone; to the east at the northwest corner of Speedway Boulevard and Harrison Road is a retail and pharmacy in the C-1 commercial zone and further east across Harrison Road is developed with Oasis Harrison, a subdivision with detached single-family homes in the C-1 commercial zone; to the south across Speedway Boulevard is a City of Tucson Sun Tran transfer station in the C-1 commercial zone and Harrison Estates Condominiums and Casa Bonita Condominiums, both residential multi-family development in the R-2 medium density residential zone.

Rezoning Presubmittal Meeting: The applicant attended a presubmittal conference meeting on April 21, 2015. Meeting discussions included discussion of the proposed T.E.P. substation and compatibility of mass and scale of proposed infrastructure and wall enclosure with surrounding non-residential and residential development. Discussed landscape buffering and view sheds. To mitigate any noise impacts such back diesel generators and that any future graffiti visible be removed within seventy-two hours of observation.

In addition, the presubmittal included the following information related to rezoning case C9-86-45: See attached Rezoning Case C9-86-45, Preliminary Development Plan and Rezoning Conditions. We have reviewed your concept plan and determined that your proposal is a minor change to the PDP subject to approval of the Special Exception case, and compliance with the C9-86-45 Rezoning Conditions. The structures / transformers will need to be setback 60 feet from north and west property line; wall for the substation facility can be 10-foot; will need to meet all landscape requirements. Please review the Rezoning Conditions to make sure that your proposed project can meet these conditions. Also attached are the following: copy of the Rezoning Ordinance, Drainage Letter, and Letter of Understanding with neighborhood.

Neighborhood Meeting: The applicant held an on-site neighborhood meeting on July 22, 2015 from 6:00 PM to 7:30 PM. Applicant has provided the required neighborhood meeting material: mailing notification, copy of labels, notice letter, neighborhood meeting summary, and sign-in sheet. The sign-in sheet indicated17 area residents attended the neighborhood meeting and 6 T.E.P employees attended.

Land Use Policies: The Pantano East Area Plan, the Wrightstown Neighborhood Plan, and Plan Tucson provide land use guidance for this site. Generally, the Plans support the requested use when visual impacts, setbacks, and landscaping and buffering elements are addressed.

Pantano East Area Plan, Residential Policy 3, requests and states to ensure the compatibility of new development with existing land uses. Wrightstown Neighborhood Plan supports medium density residential, office and neighborhood commercial.

Plan Tucson identifies this area in the Future Growth Scenario Map as a "neighborhood center" category. The Plan supports neighborhood centers with mix of small businesses surrounded by housing and accessed internally and from nearby neighborhoods by pedestrians and bikes friendly streets and by transit. Furthermore, Plan Tucson, guidelines LT28.1.3 states that above-ground utilities and structures to be designed with improved appearances.

Assessment: The Special Exception, SE-15-66 T.E.P - Harrison Road application proposes a utility substation within a parcel zoned C-1, commercial zone. The substantial infrastructure improvements proposed for the T.E.P. Substation is located on the northern half of the L-shaped parcel. The proposed ground equipment, a T.E.P. communication tower with a height of 70 feet and six light poles with a height of 60 feet each are being proposed within a ten foot tall masonry wall enclosure of approximately 180' X 350. ' The proposed infrastructure to be within the enclosure will be setback 30' from the interior of the wall enclosure. Two proposed 20 foot wide drives are shown, one from Harrison Road and a second from Speedway Boulevard. A proposed detention/retention basin is located immediately to the west of the substation structure and is approximately 120'x 200'.

Staff acknowledges that it is difficult to disguise a 180' x 350' utility substation. The distance to the nearest housing unit is approximately thirty (30) feet to the north, and forty-three (43) feet from the Harrison Road ROW. At the rezoning presubmittal staff's concerns includes how the applicant would address potential impact on neighboring residents. The applicant includes in the special exception submittal, photo view shed simulation from around the full perimeter of the site and building elevations of existing building(s) and elevations of perimeter wall to document match in texture and color of the proposed ground equipment lease area wall enclosure. Mitigation measures staff will evaluate are, but not limited to; planted vegetated buffer, including trees, along the north, east and southern walls of the substation to help mitigate its visual impact. Mitigation of any potential noise generated by ground equipment, including stand-by generators, will be considered as potential special exception conditions of approval. Staff will evaluate the noise mitigation plan as it applies to area residential development, especially directly to the north and west of the site. The full special exception submittal to address applicable policy compliance and will be subject to being consistent with the general direction of the applicable Plans. Staff will evaluate how the Jasmine Wash is being incorporated yet sustained as a natural wash area within the retention/detention design. Staff supports maintaining a vegetated riparian zone on either side of the wash to help clean and slow down stormwater runoff generated by the proposed substation. This and other water harvesting measures may allow for a smaller detention/retention basin and help to mitigate the overall visual impact on the surrounding residential neighborhood. Staff will also address how removal of graffiti should be removed within seventy-two hours of observation.

The proposal is in general compliance with the Pantano East Area Plan and Plan Tucson, and does not require a plan amendment. Staff recommends that the rezoning application be distributed for further processing.
