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.
Sidewalks: In keeping with the nearby neighborhood conventions, no sidewalks
shall be required.
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.
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.
