The City's own planning work says the ground here limits where streets and roads can go. The soils across the planning area are predominantly Woo, Stanislaus and Dosamigos, and the majority carry a moderate to severe shrink-swell problem that constrains the siting of dwellings, commercial buildings, streets and roads; most are rated moderate for shallow excavation because they are too clayey and wet. At the proposed basin sites groundwater can be as shallow as about 3.8 feet, and depth to groundwater falls from west to east across the city.
Flooding here comes from drainage, not from a river. The General Plan traces it to poorly developed surface drainage on flat topography, clay soils and a high water table, with free water five to twenty feet below the surface, and records no adequate municipal drainage north of North Avenue. Storm water is collected and passed to the irrigation district, and a lot in that system holds water while it waits its turn. Caltrans follows that water into the base, where it weakens the support the surface needs.
Gustine's paved yards work for food plants, and food plants run trucks. The dairy and packing operations that grew out of the Miller and Lux canal are still the city's largest employers, and the City keeps its industrial uses near the eastern border away from housing; the town sits near the crossing of three trucking routes. Route 140 carries 5,500 to 7,200 vehicles a day at Fourth Avenue. Loaded axles over weak or wet material is the case Caltrans answers with a dig-out.
Over half of what is paved here has been in service for decades. Of 2,169 occupied homes, 1,111 are more than 40 years old, with 450 built in the 1970s and 324 in the 1960s, against 480 added between 2000 and 2009. The City is working through the older surfaces where it can: in September 2024 it filed for a Railroad Avenue rehabilitation planing and repaving about 51,737 square feet of asphalt concrete. A private lot of that age needs the same decision made about it.
The season closes early here and the fog closes it further. Most of the year's rain falls from late October through early April, and the county hazard plan rates dense fog for Gustine as extensive in area, highly likely and of high overall significance, running November through March and in some years into May. Paint is kept off a lot where fog or condensation could reach it. Where a lot is marked out again in the dry months, the accessible stalls it touches come with it.
The revised storm drain master plan proposes nine detention basins sized to hold a 10-year storm and pump a 50-year storm out within 48 hours, and warns that pumped discharge cannot be assumed uninterruptible after a history of pump failures and power disruptions.
Gustine is 30 road miles from the Modesto base, at the crossing of State Routes 33 and 140 near Interstate 5. The marked plan, the photographs and the measurements build one file.
The request sets out the property and the state of its surface. The visit walks it with the owner, the manager or the plant's operations lead: where trucks enter and turn, which shifts the yard is busiest on, and what has to stay open at every stage. Site visit scheduled at a time that suits you. Start date set in the written estimate.
A lot plan is marked with each distress under its own name, alligator cracking in the wheel paths kept apart from longitudinal cracking at joints, with transverse and block cracking, potholes, raveling and oil spots drawn separately. Where water stands while the system pumps down is added with the inlets, and the accessible stalls are measured.
Permits come from the City of Gustine Building Division at City Hall on Fifth Street, which contracts its plan check; permits run two to six weeks after planning approval.
Line items by area and by length, with repair listed apart from the surface work and the findings that would change either figure.
Work goes between April and October, since most of the year's rain falls from late October through early April and the fog season runs through the winter. A plant yard is phased around its shifts, downtown frontage kept trading, irrigation shut off five business days before a seal, and nothing placed with rain forecast during application or curing.
Removals are saw cut two inches to a true line; cracks blown clean and dry before treatment; every inlet covered through the seal.
Handover is the marked lot plan, photographs of each area before and after, the stall and aisle measurements, the product data sheets and the warranty terms from the assigned contractor.
Gustine covers 1.6 square miles at the crossing of two state routes, with its plants to the east and its housing on a quartered grid.
Downtown sits in the north-east of the city, and the City is revitalising it while keeping its original character, looking at architecture and shop facades. The 2021 flood action proposes street drainage gutters in the downtown area, which is the same water that stands on frontage parking after a storm.
Bounded by the city limits north and east, West Avenue to the west and South Avenue to the south, and made up mainly of commercial and industrial zoning with the city's largest higher-density areas. Vacant sites on 5th and 6th Avenues are to be rezoned for new homes, which brings new parking with them.
North of South Avenue and west of West Avenue, mostly single-family, with newer and larger housing at its northern and western tip. The irrigation district canal borders the western edge of the city, and the General Plan treats it and the storm water ponds as hazards, with warning signs posted.
South of South Avenue and east of West Avenue, mostly single-family and public institution zoning, with a vacant 6.21-acre site at Sullivan Road and Grove Avenue inventoried for 62 units. The 33-unit Garden Apartments sit here, and apartment parking takes irrigation at its edges as well as daily traffic.
South of South Avenue and west of West Avenue, mostly single-family and public institution zoning, with a 2.20-acre site on Highway 33 to be rezoned for 44 units. Highway frontage parking takes its wear at the apron, where vehicles turn off a state route under power.
The General Plan found no adequate municipal drainage north of North Avenue. The community ditch runs parallel to the avenue, was designed for irrigation, grows smaller toward the east and is partly pipelined, carrying irrigation water in summer and drainage in the wet season. Paved edges beside it stay damp for months.
The Borrelli Ranch subdivision drains through the High School Ditch system on the north side of the city, which the storm drain master plan judged a viable route for detained runoff. A subdivision draining to a ditch depends on its own surfaces getting the water there in the first place.
Route 140 carries 5,000 to 7,200 vehicles a day between Linden Avenue and Fourth Avenue, and the City has listed a bike lane project, a median safety project and a roundabout as in design along this corridor. Frontage aprons here share their entry points with all of that traffic.
The cheese plant stands south of Route 33 between Second and Third Streets with homes to its south and east; a noise reading of 68.8 dBA was taken about 120 feet from its cooling tower in February 1999. Plant yards and the residential streets beside them are surveyed and treated as separate jobs.
A 42-inch City storm drain follows the Meredith Avenue extension and a 24-inch line runs along Carnation Road, with an irrigation district pipeline parallel to Meredith. In September 2024 the City filed for a Railroad Avenue rehabilitation planing and repaving about 51,737 square feet of asphalt concrete.
About 219.2 acres at Sullivan Road and Hunt Road were proposed for annexation with prezoning, new roads and utilities, with the district's main canal listed as the waterway. Vesting tentative maps have been approved for three developments in the master plan area. New roads there are built from subgrade up.
The City airport lies about 1.5 miles east of town on roughly 45 acres with a 3,200-foot runway and eighteen hangars, and the City's twelve-pond wastewater marsh system is out this way too. This is the part of the city where pumps were installed with federal grant funds to reduce flooding.
The City of Gustine Building Division, part of the Community Development Department at City Hall on Fifth Street, which processes permits for all construction inside city limits including plan check and inspection. The City has limited staff and contracts independent reviewers, and building permits take two to six weeks after planning approval, with a first plan review of one to 24 working days. The contractor assigned to the request pulls the permit.
Between April and October. Most of the year's rain falls from late October through early April, and the county hazard plan rates dense fog here as extensive in area, highly likely and of high overall significance, running from November through March and in some years into May. Rain in the curing period rules a seal out, and paint cannot be applied where fog or condensation could damage it, so striping in particular waits.
It may well be part of it. The City's planning work records that the majority of soils in the planning area carry a moderate to severe shrink-swell problem, enough to limit the siting of buildings, streets and roads, and that most are rated only moderate for shallow excavation because they are too clayey and wet. Groundwater can be as shallow as about 3.8 feet at some sites. Keeping water out of the material under the surface is much of the answer, and where the ground itself will not drain the grade and the drainage are dealt with first.
It goes to a permitted facility that takes it. The City requires a CalGreen waste management plan showing 65 percent diversion before it approves a permit for new construction, remodels or demolition, unless an approved mixed construction and demolition facility is used. CalRecycle notes that recycled aggregate is produced by crushing concrete and sometimes asphalt, with road base as its main market, and Caltrans allows reclaimed asphalt up to 25 percent of its own aggregate blend.
The table runs by parking facility: one accessible space for a facility of up to 25 spaces, two up to 50, three up to 75, four up to 100, five up to 150 and six up to 200, and where a property holds more than one parking facility each is counted separately. At least one in every six accessible spaces, or fraction of six, has to be a van space, so the first accessible space on a small lot is a van space.
At least 24 hours for the section that has been sealed, which is the period Caltrans holds traffic off a parking area seal, and it is not striped until it is dry. The instructions issued by the maker of the product being used govern anything beyond that, and the crew works to them. Because the lot is taken in sections, one part stays open while another cures rather than the whole surface closing at once.
