Concept Plan at 1st reading
This is the site plan that City Council reviewed at 1st reading. The proposed site plan shows three one-story office buildings totaling approximately 17,360 square feet and one open
space lot on approximately 2.25 acres to the east. Each building is proposed to be on a separate lot, so the buildings may be constructed at the same time or separately. The lots will
share common driveways and parking by way of a cross access, reciprocal parking and maintenance agreement, but the lot lines have been configured so that each lot parks on its own. A
variance to the Subdivision Ordinance requirement that all side lot lines be perpendicular to the right of way is requested to allow the lot lines as shown has been requested. All of
the buildings will use one trash receptacle that is shown on the proposed Lot 4. Lot 1 is proposed as an approximately 0.716 acre open space lot with an existing retention pond that
will remain. The total open space shown for the development is approximately 1.12 acres, or 50% of the net acreage. The O-1 Office district zoning, which is the base zoning for the
S-P-2 zoning, allows up to 65% impervious coverage. All lots meet the setback requirements of the O-1 Office District zoning except for the side lot line along the east side of Lot 2,
which abuts the open space lot. The O-1 district requires a side yard setback of 15’ and a 5’ setback is requested per the S-P-2 zoning regulations.

S-P-2 Regulations
12
Example of Building Architecture
Since the request is for a Zoning Change and Concept Plan only, a Site Plan that conforms to the approved S-P-2 zoning district zoning must be approved by City Council following a recommendation
by the Planning and Zoning Commission prior to the issuance of any building permits. The Site Plan approval will include elevations, a color-coded landscape plan and any other exhibits
required for Site Plan approval. The applicant is proposing that the buildings match the architectural style and materials of the existing building that is located at 601 Zena Rucker
Rd. at the southeast corner of Byron Nelson Parkway and Zena Rucker Rd. The façade materials are brick and stone with a composition shingle roof. The elevations that are submitted with
the application for a site plan must conform to the examples approved with the S-P-2 zoning.

Proposed Aerator (or equal)
To address concerns of the Planning and Zoning Commission at their November 5, 2015 meeting, the applicant added an S-P-2 regulation stating that an aerator will be provided in the existing
retention pond on the site. A cut sheet of the proposed aerator (or similar type) was provided in the packet.
16
Variance Request
Subdivision Ordinance No. 483, as amended, Section 8.01(D) requires that all side lot lines be perpendicular to the right of way lines or radial in the case of a cul-de-sac or curvilinear
design. The applicant is requesting a variance to allow the lot lines as shown in order to provide the required number of parking on a lot by lot basis.
The request for a variance to the subdivision ordinance requirement that all side lot lines be perpendicular to the right of way to allow the lot lines as shown that was covered on an
earlier slide is detailed here.
17
Tree Preservation Plan
There is approximately .05% existing tree cover on the site. If the case was a request for a straight zoning change, 70% of the existing canopy would be required to be preserved. For
property sought to be zoned, S-P-2 Generalized Site Plan District, the City Council shall consider the application for a Tree Conservation Analysis or Plan in conjunction with the corresponding
development application. The applicant is proposing to preserve approximately 37.5% of the existing tree cover. The existing tree canopy to be removed consists of three hackberry trees
and two trees less than 6” caliper inches.
