COUNCIL MEETING DATE: JANUARY 5, 2021 CITY COUNCIL AGENDA ITEM #10 STAFF PREPARER/CONTACT INFORMATION: Sylvia Carrillo, City Administrator scarrillo@sunsetvalley,org COUNCIL SPONSOR: Mayor Bruner ([email protected]) SUBJECT: LAND DEVELOPMENT CODE/VARIANCE REQUEST DESCRIPTION: Presentation and discussion of a requested variance to Section 4.301 (d) of the Land Development Code to allow for increased impervious cover for the business located at 4715 South Lamar. (Mayor Bruner/Administration) BACKGROUND: 4715 South Lamar (4715) was first developed as Wolfe Nursery in 1993, when impervious cover limits were set at 50%. The current Land Development Code places impervious cover limits at 18%. The initial development for this property required a variance for placement of the required water quality facilities within the twenty-five-foot vegetative buffer along the right of way, as well as the use of overhead utility lines. On August 3, 1993, the City Council approved the site plan for development of Wolfe Nursery. In order to build Wolfe Nursery in 1993, several development right transfers took place. The site is approximately 3.94 acres. However, the site plan indicates that the property has an area encompassing 4.55 acres. This is due to the transfer of impervious cover from 2 other locations. The first: In 1993, impervious cover was transferred from what is currently the City-Owned property where the Farmer’s Market is held. This transferred an additional 18,508 square feet of impervious cover to the property of 4715 by removing that amount of allowable impervious cover from the City owned property. The restrictive covenant for that transfer can be found here. The second: Offsite mitigation for the AISD Parking Lot is also listed as land credited for impervious cover calculations. This was an area within the AISD parking lot that had asphalt removed and trees planted between the site at 4715 South Lamar and the City- Owned property. This provided an additional 8,048 square feet of impervious cover to the site at 4715. Based on these transfers, when the property was first developed in 1993 it was estimated to have approximately 43% impervious cover. In 2013, when the property went from a single tenant to multiple tenants a full calculation of impervious cover was determined for the site. With the credit from the other properties, the impervious cover is determined to be 47.4%. If the credit from the other properties was removed, impervious cover on this site is estimated at 56.79%. The applicant has provided a conceptual plan of the project as well as a letter documenting their intentions with the project. The plan includes building a WellMed at the site that would include a medical clinic and senior activity center. The applicant is proposing a significant expansion of the building as well as additional parking. The proposed impervious cover, with the existing credits and transfers, would be 56.6%. Without the transfers, the estimated impervious cover on the site is approximately 65%. Because the project exceeds the 50% threshold, several aspects of the project will need to come to current code compliance. This includes the building code in the new portion of the building, landscaping, water quality, and buffering. The applicant is aware of such requirements. A preliminary review of the project was conducted by the City Engineer and is attached. This project is in a conceptual phase and provides an opportunity for the City of Sunset Valley to consider how it will approach redevelopment. Although there are challenges, and the project does not meet current standards, the City can work with the developer to design a project that is mutually beneficial while also protecting water quality. This can include new and innovative ways of addressing water quality controls onsite. The developer is proposing to conduct a series of design charrettes if the City is amenable to the concept. This meeting will provide the opportunity for the City Council and residents to provide feedback and ask questions regarding the project. A more refined plan will return to Council for formal action at the January 19th meeting. APPLICABLE CODE SECTIONS: LDC Chapter 4 – Watershed Development FUNDING: N/A STAFF RECOMMENDATION: Review council questions/queries and refine the project with the applicant for formal action on January 19th.

WELLMED MEDICAL GROUP DRAINAGE & WATER QUALITY PLAN PROPOSED DRAINAGE MAP C2.0 December 3, 2020 Sylvia Carrillo, City Administrator City of Sunset Valley Subject: 4715 South Lamar Blvd – Variance Request for additional Impervious Cover Ms Carrillo, The commercial development located at 4715 S. Lamar Blvd. was originally approved for Wolfe Nursery in 1993 with 43 percent impervious cover and complied with the State regulations for the Edwards Aquifer in effect at the time. The site was redevel- oped as a restaurant with a site plan approved by the City on October 6, 2005, Permit No. 05-1007, with impervious cover total- ing 47.5 percent. The purpose of this letter is to request a variance to Chapter 4 of the Land Development Code for the planned redevelopment in the attached packet. We are proposing to expand the existing building over the existing parking lot and add approx. 19,500sf of new building. This would require us to rebuild the parking which requires an increase of impervious cover to 56.6 percent, an increase of 9.1 percent from current impervious cover.
