The Low Density Residential category is for detached single-family residential development at a net density of one or fewer dwelling units per acre. Net density is the number of dwelling
units per net acre, which excludes acreage in all public rights-of-way. The purpose of the Low Density Residential land use category is to provide for and to protect low intensity detached
single-family residential development that promotes the openness and rural character of Southlake.

Proposed Concept Plan
Proposed “SF-2” Lot – ± 2.5 Acres
Proposed “SF-2” – ± 4 Acres
Proposed “RE” Lot – ± 7.240 Acres
Fire Marshal comments
The concept plan proposes two SF-2 single family residential lots adjacent to S. White Chapel and on RE Residential Estate lot to the east. The SF-2 lots are approximately 2.5 acres
for the northern lot and approximately 4 acres for the southern lot. The SF-2 district requires a minimum lot area of 2 acres. The proposed RE lot is approximately 7.24 acres. The RE
district requires a minimum lot area of 5 acres. The RE lot shows the front building line moved back so that the 300’ minimum lot width that is required in the district is met. A variance
is required to allow the panhandle lot as shown. I have a separate slide that covers the variance requests.
City sewer is available at the northeast corner of the site, so all three
lots will be required to connect to City sewer.
There are a couple of Fire Marshal comments that will have to be addressed prior to issuance of building permits. There must be approved
turnarounds to allow fire trucks to get within 150’ of all unsprinklered buildings and all buildings must be within 1000’ of a fire hydrant on a hose lay basis.
