Why asphalt paving is needed in Salida
Salida's plan sets aside more industrial ground than built-up town. The Amendment Area of the 2007 Community Plan runs to about 3,383 acres, of which 1,259 are Planned Industrial and 490 Business Park, most of the industrial land in the north-east with its traffic routed to a planned expressway. Yards built for that traffic take loaded axles on the same lines every day, and Caltrans' patching guidance puts digouts, not patches, where the support below has degraded under water.
Half of Salida was built in one decade, so its pavement is ageing together. Of 4,337 homes, 2,174 date from the 1990s and the median year built is 1993, and the shops, school lots and business premises that serve them are the same vintage. Caltrans' preservation guidance describes what thirty years does: oxidation and volatile loss harden the binder until it fails cohesively and the surface ravels under traffic.
The freeway ramps put more vehicles past Salida than live anywhere near it. State Route 99 carries about 137,000 vehicles a day at the Kiernan Avenue junction and 134,000 at Hammett Road, with 27,500 on Kiernan itself east of the freeway. Highway commercial lots at those interchanges work as turnarounds for cars and trucks alike, and the entry throats and fuel aprons are where their surfaces give out first.
Rain here reaches places it is not supposed to, and a lot is one of them. Flows at the Pirrone Road sewer plant climb with rain from December through March, and the largest recent peak day, 1.88 million gallons on 25 October 2021, followed 1.34 inches at the Modesto airport on the 24th and 0.97 the next day. The same NOAA normals put April to October at an inch of rain or less a month, which is the window for seals and overlays.
School and civic lots are where the accessible stall set gets looked at hardest. Joseph Gregori High School on Stoddard Road, Vella Middle School on Toomes Road and the Salida Union School District office on Sisk Road all park visitors as well as staff, and the stall nearest each entrance carries the requirement. The ADA.gov restriping brief makes those spaces part of any restripe, and California's Chapter 11B sets the widths, marking and signs.
Salida's storm drains are paid for through County Service Areas run by Stanislaus County Public Works, and in August 2020 the Board of Supervisors authorised an application to extend CSA 4 over all of Salida's benefiting parcels, about 4,400. Who maintains the drain a lot empties into decides who fixes a blocked one.
Asphalt paving, as delivered in Salida
Salida is 7 road miles north of the Modesto base on Highway 99, in at Kiernan Avenue or Hammett Road. The plan marked on the first visit is the record the whole job is built on.
The request comes in with the service and the town already set, and a site visit follows with the paving contractor assigned to it. The lot is walked with the owner or manager, noting gates, truck routes and the hours the premises are busy. Site visit scheduled at a time that suits you. Start date set in the written estimate.
Distress is marked on the plan by type: alligator, longitudinal, transverse and block cracking, potholes, raveling and oil spots, with the low spots that hold water and the inlets they drain to. Accessible stalls and aisles are measured against Chapter 11B and the surface rated on site.
One treatment follows: crack treatment and seal, repair and seal, grind and overlay, or reconstruction. Salida is unincorporated, so a permit goes through the Stanislaus County Building Permits Division on 10th Street in Modesto.
Line items by area and length, repair separated from the surface work, with the basis of the figure written into the estimate.
A Broadway shop, a Stoddard Road school and a Ciccarelli Road yard all have different quiet hours, so the phasing is set to them: school lots between terms or at weekends, commercial lots in sections. Irrigation goes off five business days before a seal, and nothing is placed with rain forecast.
Saw cuts two inches to a true line, digouts filled with hot mix, cracks treated and cured, oil spots primed and every drain inlet covered before a seal.
Handover is the marked plan, the stall and aisle measurements, photographs of each area before and after, the product data sheets and the warranty terms from the assigned contractor.
Where asphalt paving is needed in Salida
Salida's paving divides between an old commercial core, two freeway interchanges, school and industrial campuses and a river edge.
Downtown Salida and Broadway Avenue
The County treats Broadway as Salida's commercial core, with a landscaped median west of Curtis Street, a concrete median and parallel parking to the east and an alley behind the lots. Alley approaches and small rear lots take the delivery traffic and break at their edges.
Salida Boulevard
The fire district's only staffed station stands at 4820 Salida Boulevard, shared with the Sheriff's Office. An apparatus apron carries concentrated axle loads on a short run of pavement, so its joints and turning areas are surveyed separately from the parking beside them.
Kiernan Avenue interchange
The SR 219 junction with Highway 99, rebuilt from 2015 with new ramps and a storm drain pump station. About 137,000 vehicles a day pass on the freeway and 27,500 on Kiernan, and the commercial lots here work as turnarounds for cars and trucks.
Hammett Road interchange and the north-west Amendment Area
Highway commercial west of Highway 99 and two Business Park areas beside the interchange, with the freeway carrying about 134,000 vehicles a day here. Planned roads of six and up to ten lanes mean lots built now will meet heavier frontage traffic later.
Pirrone Road and the wastewater plant
The Salida Sanitary District plant at 6200 Pirrone Road, between the Stanislaus River and an MID canal, with rapid infiltration and percolation ponds around it. Service roads through a pond field stay damp underneath, which is where a patch keeps having to be redone.
Stanislaus River Park lands
About 244 acres along the river held in habitat and flood easements controlled by the Army Corps of Engineers, planned for a regional park that the County does not expect within twenty years. Any paved access here is thin and takes seasonal, not daily, traffic.
Stoddard Road and Sisk Road
Joseph Gregori High School at 5518 Stoddard Road and the Salida Union School District office at 4801 Sisk Road, with the former Modesto Tobacco and Candy and Shell Lab sites nearby. School lots fill and empty in short bursts, hard on drive aisles and painted crossings.
Toomes Road and Murphy Road
Flory Industries at 4737 Toomes Road, Vella Middle School at 5041 Toomes Road and BMC West Lumber Company at 4237 Murphy Road. A lumber yard runs forklifts and flatbeds over its apron, which wears the surface faster than any car park in Salida.
North Gateway planned industrial lands
Planned Industrial ground east of Sisk Road inside the area bounded by Ladd Road, Dale Road, the Pelandale Expressway and Sisk Road. New industrial yards start with subgrade and base, and a lot built on that base holds its surface for years.
Ciccarelli Road and Ladd Road
The unstaffed Salida Fire Station at 5551 Ciccarelli Road, rated in excellent condition, and the station at 1330 Ladd Road, rated poor and rented out to a private business. Pavement that is barely used still ages, ravels and cracks with no traffic on it at all.
The existing plan area and the Sanitary District
About 1,485 district acres covering most of the community developed before 2007, with 4,038 residential and 238 commercial sewer connections. Driveways and small commercial lots of that age make up the bulk of the routine repair and seal work here.
South of Kiernan Avenue
Parts of the Salida Fire Protection District south of Kiernan lie inside the City of Modesto's sphere of influence, and two areas were annexed to the City without leaving the district. The permitting authority for a lot here is confirmed parcel by parcel.

Questions from Salida property owners and managers
Stanislaus County, through the Building Permits Division at 1010 10th Street in Modesto, which states that a permit is required for new construction, additions, alterations, upgrades, rebuilding and remodeling and issues it to the property owner or the contractor. The County lists Salida under its unincorporated areas, and LAFCO records that land use decisions inside the Salida district boundaries stay with the County. The contractor the request is handed to pulls the permit where one is needed.
April to October. Those months carry an inch of rain or less each at the Modesto airport normals station, against 2.57 inches in January, 2.22 in February and 2.21 in December, and surface temperatures then stay above the minimums hot mix, seals and paint need on most days. Rain during the application and curing period is what rules the wet half out, and a patch placed in the wet is a temporary one until the lot can be dug out properly.
Because winter is when the water gets in and the traffic keeps working it. Rain here reaches even the sewer pipes, with plant inflow climbing from December through March, and a lot with open cracks takes it straight into the base. Caltrans describes a pothole as the point where a small, badly distressed area is carried away by water and traffic together, and it treats a wet-weather patch as temporary. The permanent fix is a dry-season digout of the whole distressed area.
Stanislaus County Public Works, funded through County Service Areas rather than a city utility. CSA 10 covers parks, storm drain and street sweeping, CSA 4 is a storm-drain-only area within Salida, and in August 2020 the Board authorised an application to extend CSA 4 over about 4,400 benefiting parcels. That matters on a paving job because a lot draining into a public system that is full will keep standing water whatever surface is laid over it, so grading and drainage comes before paving.
Yes, in sections. The plan divides the lot so that one part is closed while the rest carries traffic, with entrances and accessible stalls kept usable and put back first. Caltrans holds traffic off a fresh parking area seal for at least 24 hours and does not allow striping over it until it is dry, so each section has its own closed period. On a school campus the phasing is usually set to a break or a weekend instead.
It leaves as grindings and goes to a plant that takes them, where the material is crushed for road base. CalRecycle describes recycled aggregate as produced by crushing concrete and sometimes asphalt, with road base as its primary market, and Caltrans allows reclaimed asphalt pavement to replace up to 25 percent of the aggregate blend in its own hot mix. Where no plant is in reach, the material goes to a permitted facility instead, and the tickets go into the job file.
