The purpose of the request is to amend the “S-P-2” Generalized Site Plan District zoning for Lot 4R, Cornerstone Business Park to revise the previously approved elevations for the TDDC
Ambulatory Surgery
Center. The applicant is proposing a stucco façade on portions of the northwest and northeast sides of the building where a glass façade was previously approved. Changes
to the parapet heights and the length of the blade wall were originally
requested, but those changes were removed from the request after the Planning and Zoning Commission denied the
changes at their June 8, 2017 meeting.

The future land use designation is Industrial.

Here is a rendering of the entrance to the surgery center. The primary building materials are stucco, stone and brick.
Lot 4R, Block 5, Cornerstone Business Park is in the Non-Residential
Development Overlay Zone, but since the lot is more than 200’ from Nolen Dr., the development is not subject to the General Development Standards in Zoning Ordinance No. 480, as amended,
Section 43.19(d), which includes regulations regarding building articulation, masonry requirements, mechanical screening, screening of trash receptacles, etc. The materials shown do
meet the masonry requirements in the Overlay Districts.

Landscape Plan at 1st reading

The applicant added five crape myrtles at the direction of the Planning and Zoning Commission at the August 4th meeting. The plan presented to City Council at 1st reading is on the right.
The
existing trees to be preserved on the property are shown to the east of the building. The existing S-P-2 zoning does not require bufferyards along interior lot boundaries. The required
plantings for the east bufferyard are shown on the plan with existing tree credits being taken for the required canopy and accent trees. The required interior landscape plantings are
provided toward the main entrance of the building.

as an option. Two parking spaces along the drive to the north have been removed and replaced by a landscape area with a live oak and 65 Mexican Feathergrass Plants. The applicant would
still like to have the 50 parking spaces as shown on the left, but the plan on the right with 48 spaces is an option.

Lot 4R S-P-2 Zoning
A comparison of the proposed S-P-2 zoning district to the base O-1 Office District uses and regulations is shown here. As stated previously, the ambulatory surgery center has been added
as a permitted use in the S-P-2 district. The required parking for a medical office building per the off street parking requirements in the Zoning Ordinance is one space per 150 square
feet of floor area, which would result in 74 required spaces. An S-P-2 regulation has been added to allow the required parking to be based on 10 spaces per procedure room with 5 rooms
proposed for a total of 50 required spaces. A regulation has also been added to allow for a reduction in the size of the required loading space from 10’ x 50’ to 10’ x 35’.
39
Parking Analysis
A total of 10 spaces are required per Operating Room/Procedure Room:
a) 5 patient vehicles based upon the following distribution
1 patient in lobby
1 patient in pre-op area
1
patient in procedure room/OR
2 patients in the PACU
b) 5 staff vehicles based upon the following distribution
1 staff member to remain in the procedural/OR room
2 nurses/medical
staff assisting physician
1 administrative staff member
1 physician
The applicant has provided this parking analysis as justification for the 50 parking spaces that are proposed.
