Pool shells on shallow, rocky ground
At the point the Census Bureau uses as Jonestown's center, the USDA soil survey maps Brackett-Rock outcrop complex on 1 to 12 percent slopes. Its main soil, Brackett, makes up 68% of that unit and is shallow, with soft bedrock at a typical depth of 46 centimeters, about 18 inches, and bare rock outcrop makes up another 20%. That describes one mapped point, not every lot in town.
The City's development code ties how deep a lot may be cut, and how high it may be filled, to the slope of the ground. On slopes over 25%, no open cut or fill is allowed and a walled one may reach 6 feet; on 15 to 25% slopes the limits are 1 foot open and 8 feet walled; on 0 to 15%, 3 feet open and 10 feet walled. Property in a floodplain faces further restrictions, and every lot must be zoned and platted before a building permit is issued.
Plaster cracks and shell cracks
A crack that shows in the finish isn't always a crack in the structure. An article in the American Shotcrete Association's magazine reports the National Plasterers Council's position that plaster is not a waterproofing coating or membrane and has to go on a watertight concrete shell. The 2021 International Swimming Pool and Spa Code, which Jonestown adopts, asks for pool materials that give a watertight structure with a smooth, easily cleaned surface, and for assemblies of different materials to be chemically and mechanically compatible, a test any patch set into an old shell has to meet.
Rust stains coming through
When rust stains rise through plaster because the shell was shot with too little concrete over the steel, the American Shotcrete Association says keeping proper cover was the shotcrete contractor's responsibility, and that a section with reduced cover has much less durability than its designer intended.

(737) 212-9378Repairs under Jonestown's building rules
Jonestown requires a building permit to erect, alter or enlarge any structure, and its permit list names swimming pools, remodels and additions, and fences. The City's Residential Building Packet adds repairs to the work that needs permits and makes the property owner and the contractor jointly responsible for getting them, and the development code says repairs and alterations must meet the provisions for new buildings unless it says otherwise. The adopted codes, in effect since January 9, 2025, are the 2021 International Residential, Building and Existing Building Codes and their companions, with the 2020 National Electrical Code. From the same date, the City's development code also adopts the 2021 International Swimming Pool and Spa Code for every pool and spa in the city limits.
The City's application guide sends building a new pool, and replacing an existing one, to the Swimming Pool application, but it has no line for pool repair, crack repair or resurfacing, and it asks anyone unsure whether a project needs a permit to contact Development Services before starting. Applications carry the City's contractor registration form, master licenses and a certificate of liability insurance, a site plan showing the septic tank and drain field where a lot has no public wastewater service, and, in a subdivision with an active HOA or POA, written approval from its architectural committee. New homes in a subdivision governed by a planned unit development agreement, such as The Hollows, may have different restrictions.
Pool fences and front yards
No outdoor private pool at a home may be built without an enclosure at least 4 feet high that surrounds it completely, every gate in it needs a self-closing latch, and a house door forming part of the enclosure is exempt. Pools may not be built in a front yard, and the City's fencing rules add that pool fences must meet state standards and the City's adopted building codes.
Community and public pools
For public pools and spas, Jonestown adopts the state's public pool standards and the state's pool-yard enclosure law as City rules. Plans for building or remodeling one go to the City for review before work begins, the pool can't be used until it passes inspection and receives a certificate of occupancy, and its operating permit is renewed every year after a City inspection.

(737) 212-9378Lake water, Stage 2 and draining for a repair
Inside the city limits, water comes from Jonestown Water Supply Corporation, a non-profit owned by its members and tied to no city or taxing district; private wells aren't allowed unless the corporation has refused service. Its 2025 report says the water comes from Lake Travis and is disinfected with chloramines, averaging 2.2 mg/L, and it prints no hardness, calcium or alkalinity figure.
The corporation has been in Stage 2 of its drought plan since January 30, 2024, and Stage 2 allows watering once a week, between 7 p.m. and 7 a.m., on days set by address; check the corporation's current schedule. One of its Stage 2 triggers is combined storage in Lakes Travis and Buchanan reaching 900,000 acre-feet.
Under Stage 2, draining and refilling a pool is allowed for only three reasons: lowering rainwater to the normal level, repairing or replacing pool parts that have become hazardous, or repairing a leak, and the water has to go onto pervious ground or a surface that sends it straight there. Stage 3 bans filling or topping up any pool and allows new pools only with an automatic cover, though community pools may be exempt. The stage in force is checked before any water comes out for a crack repair.

(737) 212-9378How a pool crack is repaired
General practice from the American Shotcrete Association, the finish and resin makers, and the City's own papers. Your estimate covers your own pool.
Ask Development Services
Jonestown's code holds repairs to the rules for new work unless it says otherwise, so whether a permit applies is settled with the City first.
Read the crack
The American Shotcrete Association says small holes and shrinkage cracks can often be plugged or patched, while structural movement cracks call for a closer look at their cause and remedy.
Stop water coming through
SGM requires any water pushing through the shell, known as weepers, to be stopped with hydraulic cement before its finish goes on, and Prime Resins says choosing an injection resin starts with whether a crack weeps or gushes.
Patch holes and open cracks
For a small hole before plastering, the Association describes pressure washing at 3,000 psi or more, hand-patching with a nonshrink hydraulic cement of at least 4,000 psi at 28 days, then roughening the patch to take the plaster.
Prepare joints for new shotcrete
Where new shotcrete meets old, the joint must be clean and free of laitance, the weak surface film, with the gloss removed and the surface dampened; placed that way, layers bond without cold joints.
Drain and refill within the stage
Water comes out only as the water corporation's current stage allows, onto ground that soaks it up.

(737) 212-9378Established by the Jones brothers in the late 1930s
The Handbook of Texas says Emmet A. Jones and his brother Warren established Jonestown in the late 1930s and that the community incorporated in the 1980s, reporting 683 residents in 1988, 1,250 in 1990 and 1,681 by 2000. The 2020 Census counted 2,365, and the Census Bureau estimates 2,687 for July 1, 2025. Its homes are mixed in age: of 1,321 housing units in the 2020–2024 survey, 396 (about 30.0%) were built before 1990, including 146 from the 1980s and 136 from the 1970s, the 1990s added only 25 and the 2000s added 475, and the median home dates from 2005. About 86.7% are single-family detached houses and about 93.6% of occupied homes are owner-occupied, survey estimates with wide margins.
The water corporation's area reaches South Jonestown Hills south of FM 1431, the Deer Canyon and Turkey Bend Road areas, Panoramic View and the White Rim Subdivision, and across the lake to the North Rim Subdivision and Trails End Road; Lago Vista ISD serves South Jonestown Hills. Within the Census Bureau's 2025 boundaries, the city covers 6.835 square miles of land and 1.192 of water, and in a straight line its Census center point lies about 7.6 miles south-southwest of Leander's.

(737) 212-9378Jonestown pool questions
How tall can pool lighting stand at a Jonestown home?
No higher than 15 feet above the pool deck. The City's development code caps lighting for residential pools and sports courts at fifteen feet above the deck or court surface, and it exempts underwater pool lighting from its outdoor-lighting rules altogether.
What setbacks and cover limits apply on a Jonestown R-1 lot?
In the R-1 single-family district, the City's packet lists setbacks of 30 feet front, 25 feet side, 30 feet street side and 30 feet rear, a 1-acre minimum lot and a 28-foot height limit; existing subdivided lots under one acre use 20 feet front, 5 feet side, 10 feet street side and 20 feet rear. Impervious cover, the hard surface that stops rain soaking in, is capped at 40% in R-1. The packet's figures are for structures generally and give no separate pool setback, and lots under a planned unit development agreement such as The Hollows may differ, so Development Services confirms them for a pool project.
