PUBLIC HEARING: Consider a request for a Specific Use Permit (SUP) to replace the existing SUP allowing an electrical substation, for Oncor Electric Delivery Company, for the property legally described as Lot 1, Block A of Keller Wall-Price Substation Addition, being 9.12 acres, approximately 850 feet northeast of the intersection of Wall-Price Keller Road and Chisholm Trail, zoned Commercial and addressed as 851 Chisholm Trail. Oncor Electric Delivery Company, Owner/Rob Myers - Kimley Horn, Applicant. (SUP-23-0023)
Body
Background:
In 2005, City Council approved a Specific Use Permit (SUP) and site plan for an electrical substation for TXU Energy at 851 Chisholm Trail. The approval ordinance (included as a Staff Attachment in this agenda packet) tied the SUP and Site Plan together, and specified the substation would be located on a 2.67-acre portion of the 9.12-acre lot. The Applicant, now Oncor Electric Delivery Company, wishes to expand the substation to add additional equipment. The property is zoned Commercial, where an SUP is required for private or franchised utility structures.
The purpose of this item is to replace the original SUP with a new SUP that covers the entire site and is not tied to the site plan. The updated site plan will be reviewed by staff as a separate submittal.
Site Design:
The Applicant proposes a new concrete pad that will be just under 70,000 square-feet and serve as the foundation for new electrical equipment and one new approximately 865 square-foot metal structure, which will be roughly 14’ in height with no water or sewer service. There are two existing access drives off Chisholm Trail to serve the site, and all new equipment will be operated remotely so no traffic impact is anticipated. The Applicant will extend the existing 8’ masonry screening wall along the west, south and east sides of the site and construct the required 10’ trail along Chisholm Trail.
Summary:
Section 8.02 (F)(2) of the UDC states that when considering an SUP request, the Planning and Zoning Commission shall consider the following factors:
1) The use is harmonious and compatible with surrounding existing uses or proposed uses;
2) The activities requested by the applicant are normally associated with the permitted uses in the base district;
3) The nature of the use is reasonable and appropriate in the immediate area;
4) Any negative impact on the surrounding area has been mitigated; and
5) That any additional conditions specified ensure that the intent of the district purposes are being upheld.
Citizen Input:
On July 27, 2023, the City mailed out 35 Letters of Notification for this Public Hearing to all property owners within three-hundred feet (300’) of the subject site. A public hearing notice sign was posted on the site.
Alternatives:
The Planning and Zoning Commission has the following options when considering a Specific Use Permit:
§ Recommend approval as submitted.
§ Recommend approval with modified or additional condition(s).
§ Table the agenda item to a specific date with clarification of intent and purpose.
§ Recommend denial.
City Council Action:
If the Planning and Zoning Commission takes action and makes a recommendation on this agenda item, then this SUP application will be scheduled for City Council action on September 5, 2023.
