The purpose of this dataset is to provide the City of San Marcos with an authoritative GIS layer identifying parcels constrained by floodway boundaries.
This information assists city planners, engineers, and policy analysts in determining SB9 eligibility, reviewing development proposals, and ensuring conformance with local floodplain management regulations. The dataset facilitates proactive risk management and sustainable urban development practices by integrating hydrologic hazard zones into the SB9 constraint analysis process.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset identifies parcels and geographic areas within the City of San Marcos that fall inside designated floodway zones, where development is restricted under Senate Bill 9 (SB9). Floodway constraints represent high-risk flood-prone regions delineated by FEMA and local hydrologic studies. These areas are considered unsuitable for SB9 urban lot splits or housing development due to potential flood hazards and environmental safety regulations. The dataset supports planning evaluations, hazard mitigation efforts, and compliance review for residential development under SB9 provisions.</SPAN></P></DIV></DIV></DIV>
