Water in Kendall County comes from a combination of sources depending on location. Homes within Boerne city limits and Fair Oaks Ranch connect to municipal water. Properties in unincorporated areas may be served by private water supply corporations, MUD-operated systems, or private wells drawing from the Edwards Aquifer. The Edwards Aquifer Authority regulates groundwater pumping in the region, which can affect well permitting and long-term water availability. New development near the I-10 corridor has generally been served by utilities, but Hill Country subdivisions further from Boerne may rely on well systems requiring pressure tanks and periodic maintenance. Before purchasing, confirm your specific community's water source, who operates the system, and whether it is a private well or a utility connection — and get that information in writing from your builder.

Most new construction in Kendall County falls within Boerne ISD, which serves Boerne and surrounding unincorporated areas. However, communities near the eastern edge of the county — particularly in the Fair Oaks Ranch area — straddle county lines, and some portions fall within Northside ISD (NISD), one of the largest school districts in Texas serving the northwest San Antonio area. The distinction matters: Boerne ISD is a mid-size Hill Country district known for strong community identity, while NISD is a large suburban San Antonio district with different attendance zones and campus options. Verify your specific community's school district assignment before assuming — fair Oaks Ranch in particular spans Kendall, Bexar, and Comal counties with different tax and school district implications per parcel.

Kendall County's Hill Country terrain features thin limestone soils that shed rainfall quickly into the Guadalupe River and Cibolo Creek — both of which can rise rapidly during intense storms common in the Edwards Plateau region. Subdivision along these drainage corridors can include lots in or adjacent to FEMA-designated flood zones. Zone AE (100-year floodplain) properties require flood insurance with federally backed loans; new construction in these zones must meet finished floor elevation requirements above Base Flood Elevation. Even Zone X properties near creek systems can experience occasional localized flooding from tributaries. For any new construction lot within two miles of the Guadalupe River or Cibolo Creek, ask your builder for the specific FEMA flood zone designation for that parcel and whether any elevation certificate work has been completed.
