Case # ZA20-0049
Sage Group, Inc.
This Residential Planned Unit Development shall abide by the all conditions of the City
of Southlake Comprehensive Zoning Ordinance No. 480, as amended, as it pertains to
the “SF-1A” Single-Family Residential zoning district; and the City of Southlake
Subdivision Ordinance No. 483, as amended:
The following regulations shall apply to all lots, except as noted:
Minimum House Size: All new houses constructed shall be a minimum of 4,000 s.f. in
floor area.
Street: A 25’ B-B pavement section with standard 6” curb, in a 40’ Access Easement
shall be provided along the frontage of the residential lots. The cul-de-sac shall have a
100’ B-B outside diameter of paving, in a one hundred ten (110’) foot diameter
easement. Residential Lots shall not be required to front on a public street. (Subdivision
Ordinance No. 483, as amended, Article VIII Miscellaneous Requirements, Section 8.01
Lotting Requirements, A.).
Street Lights & Sidewalks: In keeping with the nearby neighborhood conventions, no
street lights nor sidewalks shall be required along the Access Easement.
Side and rear lot lines shall be configured as shown on the Development Plan.
All newly constructed homes shall be required to be protected by a fire-suppression
sprinkler system.
No separate common open space lot shall be required, consistent with the normal
requirements of SF-1A zoning, which this development is patterned after.
In the Open Space, Pedestrian Access and Wildlife Easement, no construction or living
tree removal shall be allowed.
City sewer is and will not be available at this site, so this development requests a
waiver to the normal requirement, listed in Chapter 19, Article III, Division 2, Section
19-88 of the Southlake Code or Ordinances, to install a sewage collection system that
extends to the development’s borders and throughout the development.
If, in the construction of the road, grading or drainage associated with the Access
Easement, any damage occurs to trees on the adjacent Lot 9, Block 2 of Harbor Oaks
leading to the death of those trees, such trees with be replaced, inch for inch, with
quality Red, Bur or Live Oak trees.
Open Space Management Plan:
The “Access Easement,” and the “Open Space, Pedestrian Access and Wildlife
Easement” areas in the project, and common facilities such as the access road, shall be
maintained by a Homeowners Association (HOA), to be established for the
development. All other areas shall be the responsibility of the individual property
owners, including the front yards and required streetscape trees of the residential lots.
All property owners shall be required to be a member of the HOA. Dues assessments,
required for the maintenance of the landscape easement areas and other HOA
activities, shall be mandatory.
The HOA, through a resident Board of Directors, shall be responsible for the
maintenance and operation of the protected open space within the development, either
directly or through a third-party management company. No full-time employees are
contemplated to be necessary. The expenses required to maintain the roadway and
easement areas at a quality level shall be estimated annually by the HOA Board, and
dues shall be determined and assessed on each property owner in an equitable fashion
at such a rate as necessary to maintain such a level of quality. The annual expenses for
such open space maintenance are initially estimated to be $8,000, or approximately
$1,000 for each of the HOA homeowners. Authority to enforce these requirements, and
to place a lien on the property if such dues are not paid, shall be in the form of written
Deed Restrictions and Covenants, agreed to by all property owners in the HOA at
purchase, and shall run with the land.
Provisions shall be made, in the HOA Bylaws and Deed Restrictions, that in the unlikely
event the HOA fails to maintain all or a portion of the protected open space in
reasonable order and condition, the City of Southlake may, but is not required to,
assume responsibility for its maintenance and take corrective action, including the
provision of extended maintenance. The costs of such maintenance may be charged to
the HOA or individual property owners that make up the HOA, and may include
administrative costs and penalties which shall become a lien on all property in the
development.
