EXECUTIVE SUMMARY
Details
• The City of Southlake is proposing amendments to the Zoning Ordinance No. 480,
as amended, for a Solar Energy Systems ordinance that will require a specific use
permit and regulations for the installation of solar energy systems in residential and
non - residential zones, as well as, modifications regarding On -Site Sewage Facilities.
QUESTIONS & DISCUSSION FOR 480 -YYY, On -Site Sewage Facilities (OSSF)
QUESTION: What if you have less than an acre and there is no sewer line nearby?
How can I replace my system?
RESPONSE: I believe you would be grandfathered in unless you were
rezoning /rebuilding residence.
QUESTION: What is the difference between an aerobic and anaerobic system?
RESPONSE: The anaerobic system is the traditional septic system which is not
appropriate for every soil type and has greater potential for odor,
blockage, and environmental impact. An aerobic system introduces air
into the system which grows bacteria that eat the effluent and is
typically used with spray heads; can be a costlier system.
DISCUSSION: Why is Tarrant County regulating the city's sewage systems? Why is
there so much government involvement?
QUESTION: When will Southlake offer sewer lines to all homes in the city?
RESPONSE: That would be a very costly endeavor. The sewer projects are put on
a CIP list every year. You can check with Public Works to see if your
location is on the list.
QUESTION: Once sewer becomes available, do we have to hook up?
RESPONSE: For new permits, yes.
QUESTION: Are existing systems affected by this?
RESPONSE: No
QUESTIONS & DISCUSSION FOR 480 -WWW, Solar Energy Systems
QUESTION: Does the permit allow for vacant lot use?
RESPONSE: No, each permit will be associated with a lot that contains structure(s).
DISCUSSION: Why not? It's our land... who does it hurt?
Roof mount regulations need to be more flexible.
This is too restrictive and serves no purpose.
We want the city to allow ground installations / solar farms.
RESPONSE: The Solar Energy Systems ordinance was reviewed by the Planning
and Zoning Commission and these regulations were written in
response to their concerns. This is a starting point. We will need to go
through the process to see how to regulate most efficiently. You will
have opportunities to voice your concerns during public hearings at
P &Z and City Council.
QUESTION: How much will the permit cost?
RESPONSE: A specific use permit application fee is $200.
DISCUSSION: What constitutes the free standing requirement of 10 feet from the
house?
QUESTION: How long before this gets through?
RESPONSE: It will ultimately be a City Council decision. The ordinances go to the
Planning and Zoning Commission on April 9.
DISCUSSION: What about V- shaped technology?
V- shaped roof mounting raises a fire issue... consider pole mounting.
