Lewisville planning staff identifies 33 map discrepancies; council directs targeted boundary cleanup

Planning staff presented a multi‑month review of city boundary data and recommended targeted cleanup after finding 33 apparent discrepancies between Lewisville’s GIS mapping and neighboring jurisdictions’ records.

Planning director Richard Lundke told council staff compared Lewisville’s GIS shape files with neighboring cities and assembled ordinances and survey descriptions; the initial analysis found 33 discrepancies that largely stem from projection and mapping inconsistencies. Lundke identified three specific areas needing follow‑up with Carrollton — the King Arthur Boulevard/Old Denton Road intersection, an interchange area south of the San Braver Tollway and a collector/distributor right‑of‑way that shifted with construction — plus a set of small “donut‑hole” leave-outs from older Castle Hills plats.

Lundke said some intersections currently straddle jurisdictional lines and could complicate emergency response and signage. He recommended: coordinate with Carrollton staff for boundary adjustments where the discrepancies are small (state law allows adjustments under certain distances), work with property owners to correct donut‑hole leave‑outs via petition/annexation, and limit action on Hebron strips because the appraisal district already treats affected properties as Lewisville tax interests.

Council gave direction to proceed with coordination and owner outreach and asked staff to return with more detailed recommendations.
