Liberty Hill-area land: water and sewer CCNs, service evaluation and subdivision utility checks

For a Liberty Hill-area tract, first identify who can serve the parcel and which office reviews the intended project. The City says a property must fall within its applicable water or sewer Certificate of Convenience and Necessity (CCN) area to be eligible for City service. Search the City GIS map with the water and sewer CCN layers, then compare the result with the PUC’s CCN viewer. Treat both as screening tools: a map does not promise a connection, available capacity, a price, or a completion date.

The City’s FAQ says an applicant seeking City service must submit a Utility Evaluation Application through MyGovernmentOnline with the information required from the project engineer. The City lists a 30-day review period. It also says that since May 2024 it no longer reserves utility capacity; new service requests are considered first-come, first-served based on application approvals. Ask the City and any other mapped provider to review the exact legal description, survey, intended use, demand, and proposed timing in writing before treating utility service as feasible.

A meter, nearby line, or Liberty Hill mailing address does not settle the question. The City says some area properties receive water from Liberty Hill, Georgetown, or private wells, while wastewater may be City service or an on-site sewage facility. Its mapping page says water and wastewater line maps nearest a property can be requested. Ask providers to identify the service point, extension requirements, connection and impact fees, capacity, approvals, and timing; obtain current written estimates rather than using a generic cost-per-foot assumption.

Jurisdiction matters as well. The City describes subdivision and sign regulation in its ETJ and says platting or stormwater review may apply depending on the project. Williamson County’s current subdivision regulations address utility commitments and infrastructure for subdivisions. For the actual tract, match the deed, survey and plat to the City/County boundaries and ask which authority handles each review. An existing legal lot, a new subdivision, and a project in City limits can follow different paths.

Facts to help plan the next check

• The City of Liberty Hill says a property must fall within the City’s applicable water or sewer CCN area to be eligible for the City to provide that service; the City points users to its GIS water/sewer CCN layers and the Public Utility Commission CCN viewer.
• A CCN identifies the geographic area in which a named utility provider has the exclusive right to provide retail water or sewer service; a CCN map is not a project-specific commitment of connection, capacity, cost, or schedule.
• The City says a utility service request requires a Utility Evaluation Application through MyGovernmentOnline, with information from the applicant’s engineer; the City FAQ lists a 30-day utility evaluation review period.
• The City says that, as of May 2024, it no longer allows utility capacity reservations and considers new service requests first-come, first-served based on application approvals.
• The City warns that a water meter does not always determine whether a property has utility service; its FAQ notes that water may be supplied by Liberty Hill, Georgetown, or a private well and wastewater may be City service or an on-site septic system.
• Liberty Hill’s Maps and Guides page says it can provide maps of water and wastewater lines nearest a property on request; it also says City boundary and zoning maps are informational and zoning should be verified with the Planning Department and official ordinance.
• Liberty Hill’s FAQ says its ETJ has City subdivision and sign regulations under an interlocal agreement with Williamson County; development may require platting or stormwater permits depending on the project.
• Williamson County’s 2025 subdivision regulations address water and sewer facilities, retail utility commitments, engineering review, on-site sewage facilities, and financial guarantees for subdivision infrastructure; these provisions concern subdivision review and do not establish service for an existing individual tract.
• Liberty Hill’s utility billing page identifies City water and wastewater account services, but account administration does not prove that a particular vacant parcel is inside the City’s CCN or has available capacity.
• The City’s impact-fee code covers qualifying new development in City and ETJ service areas and describes water and wastewater impact fees; the applicability and amount for a particular project must be confirmed with the City using current code, fee schedules, and project details.

Parcel-specific next checks

1. Obtain the exact legal description, current boundary survey, Williamson County appraisal account and recorded plat; do not rely on a mailing address or listing pin.
2. Check the City of Liberty Hill GIS water and sewer CCN layers and the PUC CCN viewer; note the provider name and map date for each utility.
3. Call the City and any other provider identified by the map to confirm the parcel’s service territory and the correct application contact; ask for the answer in writing.
4. Ask the City whether a Utility Evaluation Application through MyGovernmentOnline applies, what engineer-prepared information is required, and what current review timeline applies to the project.
5. Request current written information on capacity, point of connection, main extensions, easements, impact fees, connection fees, deposits, construction standards, approvals and schedule.
6. Request the City’s water and wastewater line maps nearest the surveyed parcel; a nearby line does not prove a service connection or remaining capacity.
7. If water service is not confirmed, ask a licensed well driller and the appropriate state/local offices about existing well records, groundwater suitability, permits, testing and estimated drilling conditions for the exact tract.
8. If sewer service is not confirmed, ask the responsible OSSF authority what site evaluation, soils information, system design, floodplain review and permits apply to the planned use.
9. Confirm whether the property is inside Liberty Hill city limits, in the ETJ, or in unincorporated Williamson County; ask each authority which rules apply to the exact project.
10. For a new division or subdivision, review current Williamson County/City platting requirements and obtain written utility commitments and engineering requirements before estimating total development cost.
11. Keep dated emails, utility evaluations, capacity decisions, fee schedules, maps, easements and provider estimates with the parcel due-diligence file.
