PROJECT: Sidewalk Variance Request for 2421 Greenbough Ln.
EXECUTIVE
SUMMARY: Cherie Dinger with J. Bolton Design Group is requesting approval of a sidewalk
variance for 2421 Greenbough Ln., on a property described as Lot 19, S.
Freeman No. 525 Addition, City of Southlake, Texas, and located at 2479
Raintree Dr., Southlake, Texas. Current Zoning: "SF-1A" Single Family
Residential District. SPIN Neighborhood #4
DETAILS: The applicant seeks a variance from Section 5.06 of the Subdivision Ordinance
No. 483, as amended, requiring a 5-foot sidewalk along the street frontage. This
variance request is based on the absence of sidewalks along Greenbough Ln,
the bar ditch located along the street frontage, and the existing overhead
electrical lines and poles. Approval from the City Council is required for
modifications or variations to the Subdivision Ordinance. Although payment of
the construction cost of the sidewalk into escrow with the City is an option, given
the characteristics of this street, it is unlikely that sidewalks would be practical.
