Most of Tracy went up in two decades, and the oldest quarter of it is concentrated in a few blocks. Of 27,787 units, 28.2 percent were built between 2000 and 2009, 26.8 percent in the 1990s and 16.7 percent in the 1980s, with 84 percent of the stock single-family; the population more than doubled between 1990 and 2004, from 33,500 to 74,070. The oldest housing is downtown and south of the bowtie along Central Avenue, where the City records its oldest stock and most of its rental and multifamily units.
The ground here is difficult, which is why a crack gets traced instead of filled. The City's own design criteria state that most of Tracy has expansive and corrosive soils and that liquefaction has been noted to occur, and the Housing Element rates the expansive potential moderate to high. What the survey has to answer is not the shape of the crack but whether water has passed it, because the state code makes the wall a drained assembly with a weep screed 4 inches above soil and 2 inches above paving as its only way out.
About a sixth of the housing predates the rules on removing old paint, and it sits where the city started. The survey puts 3.7 percent of units at 1939 or earlier, 2.8 percent in the 1940s, 5.2 percent in the 1950s, 3.8 percent in the 1960s and 7.8 percent in the 1970s, and the blocks along Central Avenue hold the concentration. On that stock the coating is tested before preparation, or the job runs to the federal lead renovation rule, with its notices and containment.
The largest walls in Tracy are distribution walls, and they keep water out at their joints. The Cordes Ranch plan area alone covers about 1,780 acres and is planned for 27.8 million square feet of industrial space, alongside the employers already standing on North MacArthur Drive and Pescadero Avenue. Concrete and clad steel carry no drained cavity, so the panel joints, the dock surrounds, the caps and the coating do everything, and the product is chosen inside the limits the San Joaquin Valley air district sets.
A short wet season, a hot summer and a wind exposure the code already recognises. The City's water plan records an average of 9.9 inches of rain a year with more than 85 percent of it falling between November and April, January averaging 1.9 inches, and a July average maximum of 93.6 degrees with summer days often over 100. Its design criteria give a 2 percent dry-bulb high of 101.2 degrees and put the city in wind exposure C, which is felt on every unsheltered elevation.
Tracy's building design criteria rate termite damage in the city as Very Heavy, alongside expansive and corrosive soils. Opening a wall here is as likely to turn up work for another trade as it is to confirm that the finish was the whole problem.
Tracy is 30 road miles from the Modesto base, with Interstate 205 crossing the north of the city between Interstate 580 and Interstate 5. Every elevation is drawn, photographed and priced on its own.
The request names the building, its elevations and what has shown on the inside face. Site visit scheduled at a time that suits you. Start date set in the written estimate. On a distribution building it settles which faces can be worked while docks run; downtown, the working room on narrow older blocks.
Cracking is drawn face by face, the screed line is measured against soil and paving, and window, door and penetration flashing is opened where a stain shows water behind it. Downtown and along Central Avenue the coating is sampled before preparation begins.
The City's Building Safety Division at 333 Civic Center Plaza issues permits every working day, and for a parcel in the unincorporated pocket at the north end the authority is confirmed before anything is lodged.
Crack and patch areas, recoat or repaint by surface, siding by length, flashing and sealant, each tied to an elevation, with allowances for what opens up.
Occupants are notified, openings within 20 feet are closed and the ground is covered 10 feet out. Scaffold goes up under a qualified person, no one works it in high wind without that being judged safe, and high-heat procedures start at 95 degrees.
Barrier lapped over the weep screed flange, corrosion-resistant lath, three coats and their cures; siding back with its flashing; strippings to a permitted facility.
Surfaces in and below the work area, the sills and the ground are checked clean before containment comes down. Photographs by elevation, the permit final where one applies and the colour schedule go to the owner or the association.
Tracy runs from an 1878 rail crossing out to specific plan areas, and the wall changes with every step of that.
The first part of the city, just north of the rail crossing, still holding its oldest housing and the most multifamily and rental units. Painted timber, trim and older plaster dominate, and the paint is old enough to be tested first.
Blocks cut off by the tracks, with lower-income housing and what the City calls a concentration of the oldest housing stock in Tracy. Street flooding in the older parts of town puts water at the base of walls that already carry the oldest coatings.
A semi-rural county area with no storm drain infrastructure, so rain collects in low spots; a church and a neighbouring home flooded here in January 2023. Ground that ponds beside a building is ground that buries the screed at the bottom of its wall.
Land behind the Old River levees, in the mapped 100-year zone, with base flood elevations of 13 feet west of the Sugar Cut and 22 feet east of it. Cladding that has been in floodwater is opened rather than recoated, whatever the finish looks like.
About 870 acres between the freeway, Paradise Road, the rail line and the Eastside Channel, where temporary retention basins were serving as the interim storm solution in 2012. Large plain walls and loading door surrounds here take industrial maintenance coatings.
Food, logistics and manufacturing plants line these two roads. Plant elevations are repainted around shift patterns rather than trading hours, and the metal doors, rails and bollards are coated separately from the panels.
About 1,780 acres at Mountain House Parkway and the freeway, planned for 27.8 million square feet of industrial space with office and commercial alongside. New tilt-up here starts with its joints and sealants right, which is the cheapest point in a wall's life.
A run of substantially completed residential projects from Byron Road to Linne Road, among them Huntington Park, Westgate, Sterling Park, Redbridge and Larkspur Estates. Plaster of that generation is at the age where control joints and window corners open together.
About 150 acres of housing south of Eleventh Street, with a joint-use detention basin inside the park that can overflow onto two soccer fields in larger storms. Walls that face an overflow area are checked at the screed line first.
About 416 acres in south Tracy, first approved in January 2013 and amended in 2021 to take in the Avenues, with 700 units built by the end of 2022. Newer plaster means the coating rather than the barrier is usually the question here.
The southernmost growth area, planned for 7,265 homes with 1,952 built by the end of 2022, parts of it in the higher seismic zone. Elevations here stand on open ground with no mature planting in front of them, so weathering is even and early.
Rural homes and farms where the creek fans out past Chrisman Road, flooded in 1983, again in February 2019 and again in January 2023. Farm buildings out here put siding and painted metal low to irrigated and flooded ground.
The City's Building Safety Division at 333 Civic Center Plaza, which issues permits every working day, for any parcel inside the city limits. At the north end of town there is an unincorporated county pocket around Larch Road, and a parcel there is confirmed with the County before anything is lodged rather than assumed to be the City's. The route for the particular job is settled before the estimate is written.
Not if the cause is dealt with as well as the crack. The design criteria the Building Safety Division publishes state that most of Tracy exhibits expansive and corrosive soils and that liquefaction has been noted to occur, and the Housing Element rates the expansive potential moderate to high. A survey therefore records the irrigation, the drainage and the clearance below the screed alongside the crack itself, and the estimate says what was found rather than only what was filled.
It means the wall often turns out to be two jobs. The plaster, the lath, the barrier, siding boards and panels, trim paint, coatings, sealants and wall flashing are all handled here. Wood that has decayed or been eaten is dry rot repair in Tracy and is written as its own line item, so an owner sees the two apart. Once the timber is sound, the wall is closed back to a drained assembly.
The dry two-thirds of the year, with hot afternoons avoided. The City's water plan records 9.9 inches of rain in an average year with more than 85 percent of it falling between November and April, January averaging 1.9 inches, and a July average maximum of 93.6 degrees, while the design criteria give a 2 percent dry-bulb high of 101.2. Plaster is placed above 40 degrees and each coat kept moist before the next.
It decides what can be done on a given day. Tracy is classified in wind exposure C in the City's own design criteria, and the record includes gusts strong enough to snap branches across streets and drop a tree onto a house roof. Scaffold is not worked in a storm or high wind unless a qualified person has judged it safe, and spraying is not attempted when wind would carry the material off the elevation.
Over sound plaster, yes. One coating category is made to bridge holes and minor cracks in a single thick pass, and used on a wall that has not leaked it is a fair answer. What it cannot report is whether water has reached the barrier and the lath. A stain on the inside face, a soft patch or a rust line means the section comes out and is rebuilt, and the coating is the last operation.
