PUBLIC HEARING Action Requested: Ordinance No. 1237, 2nd reading, abandoning a portion of a drainage easement on Lot 4, Block 1, Kirkwood Hollow Phase II, an addition to the City of Southlake, Tarrant County, Texas, being located at 512 Round Hollow Lane. PUBLIC HEARING Background Information: The Homeowners of Lot 4, Block 1 of the Kirkwood Hollow Phase II subdivision are requesting that the City abandon a portion of the existing drainage easement recorded in Cabinet A, Slide 6044. The easement is located in the rear yard of the property, 512 Round Hollow Lane, along the South Fork of the Kirkwood Branch. The easement encompasses 0.25 acres of the 0.71-acre property. The document was recorded on August 9, 2000 under Cabinet A, Slide 6044 granting the City of Southlake a drainage easement in the rear yard of the lots adjacent to the South Fork of the Kirkwood Branch. The Homeowners requested Cumulus Design, LLC, a Civil Engineering firm, to provide a drainage study to determine whether the existing drainage easement was larger than necessary. Upon further evaluation it was determined that the boundaries of the drainage easement were greater than required. The associated FEMA Flood Insurance Study and FIRM Map, as well as the onsite topography where used to determine the 100-year base flood elevation for the property. The 100-year base flood elevation plus one-foot of freeboard, to comply with Article V – Flood Hazard Reduction regulations, was used to determine the area of the drainage easement abandonment. The existing drainage easement is wider than the existing flood plain and, based on the results of the drainage study, will remain wider than the flood plain once the subject portion of the easement is abandoned. The drainage study from Cumulus Design, LLC has been included for reference. Item 6A Page 2 of 2 Financial Considerations: The applicant has provided the City with the filing fee costs.
