Serving Napa, CA and surrounding areas. (707) 254-6177
Napa Concrete is a licensed concrete contractor serving Rohnert Park, CA. We build and repair concrete driveways, patios, decorative flatwork, sidewalks, and slabs for homes across the city - from the original 1960s ranch tracts to the newer two-story homes in Vast Oak. We handle permits and reply within 1 business day.
Rohnert Park homeowners who have upgraded kitchens and bathrooms in their 1960s and 1970s ranch homes often want outdoor flatwork that matches. Decorative concrete - including stamped patterns, exposed aggregate, and color-stained surfaces - updates driveways and patios that were poured to basic builder standards decades ago. It also holds up well against Sonoma County clay soil movement when properly reinforced and sealed. See our decorative concrete service for design options and details.
Most of Rohnert Park's ranch homes have driveways that were poured in the 1960s or 1970s with minimal reinforcement. After 50-plus years of clay soil movement and seasonal wet-dry cycles, those slabs are often cracked, settled, or heaved to the point where repair does not make sense. A new driveway poured to current thickness and reinforcement standards will handle Sonoma County conditions for decades.
Ranch homes in Rohnert Park typically have a rear yard with access from a slider or back door - a standard layout that suits a concrete patio well. The key in this climate is building in a proper drainage slope so that winter rain moves away from the house rather than pooling against the foundation. We also see a lot of older patios in this city that were poured without adequate thickness and have since cracked from clay soil movement beneath.
Most homes in Rohnert Park were built on concrete slab foundations rather than raised foundations with crawl spaces. Slab-on-grade construction is durable, but the expansive clay soils in the Sonoma Valley cause slabs to shift, crack, or develop low spots over decades. Cracks in interior slabs that show up through flooring, or exterior flatwork that has dropped noticeably, are signs that the soil beneath has moved.
Rohnert Park's planned grid neighborhoods have sidewalks that run through most residential blocks, and panels that are heaved, cracked, or out of level are a trip hazard the city takes seriously. Homeowners are typically responsible for sidewalk panels adjacent to their property. We handle removal, proper base prep, and poured-to-grade replacement that meets current ADA and city standards.
Rohnert Park was developed almost entirely between the late 1950s and the mid-1980s as a planned community. The bulk of the city's single-family homes are ranch-style tract houses built on slab foundations, and nearly all of them still have their original concrete driveways, walkways, and patios. That original flatwork is now 40 to 65 years old. It was poured to the standards of its time - which means thinner slabs, less reinforcement, and minimal base preparation compared to what is required today. Add Sonoma Valley clay soil that expands every wet season and shrinks every dry season, and you have the conditions that cause cracked driveways and settled patios in neighborhoods all across Rohnert Park.
Rohnert Park receives around 30 inches of rain annually, mostly between November and March. Five months of saturated soil puts constant pressure on older concrete flatwork and slab foundations. The dry season then pulls that moisture back out, and the soil shrinks. After decades of this cycle, cracks appear in concrete surfaces, slab sections drop and rise unevenly, and driveways develop the characteristic edge separation and corner cracking that shows up all over the city's older neighborhoods. Newer homes in the Vast Oak and Willowglen areas were built more recently and are generally in better shape, but their foundations and flatwork will eventually face the same soil conditions.
We pull permits through the City of Rohnert Park Development Services Department and are familiar with the permit and inspection process for residential concrete work here. Rohnert Park has a consistent grid street layout across most of its neighborhoods, which makes equipment access predictable - most ranch-home lots have standard driveway widths and rear yard access from the side of the house. The newer two-story homes in the Vast Oak area on the southeast side of the city have slightly different site conditions than the original ranch tracts, including larger lots and different drainage patterns.
Highway 101 runs along Rohnert Park's western edge and is the main corridor connecting the city to Santa Rosa to the north and Petaluma to the south. Sonoma State University sits inside the city limits and is the most recognizable landmark in Rohnert Park - neighborhoods near campus tend to have a mix of owner-occupied homes and rental properties. The Green Music Center on the SSU campus is another local reference point most residents know. We have worked on homes across all of Rohnert Park's residential areas.
We also serve homeowners in neighboring Santa Rosa to the north and Petaluma to the south. If your project is in Rohnert Park or a nearby Sonoma County community, call us and we will walk you through the process.
We respond within 1 business day. Tell us what you need - a description of the work and your address is enough to get started. No drawings or measurements needed before you reach out.
We walk the property, note soil conditions, drainage, and any existing concrete being removed. The written estimate breaks out each cost item so you know exactly what you are paying for. We flag any additional drainage or base work the site requires - common on older Rohnert Park lots where original grading has settled.
We submit the permit application to the City of Rohnert Park for all work requiring one. Residential permits typically take one to two weeks to process. We confirm your start date once the permit is approved and schedule to avoid the wet season where possible.
Most Rohnert Park residential projects take two to four on-site working days. Before we leave, we walk you through the curing requirements - seven days minimum before vehicle traffic, 28 days for full strength. A city inspector verifies all permitted work.
We serve all of Rohnert Park - from the original ranch home neighborhoods to Vast Oak and Willowglen. Free written estimates, no pressure.
(707) 254-6177Rohnert Park is a planned community in Sonoma County, developed starting in the late 1950s and incorporated as a city in 1962. It sits along Highway 101, roughly halfway between Santa Rosa and Petaluma. With about 43,000 residents, it is one of the larger cities in Sonoma County. Unlike older Northern California cities that grew organically, Rohnert Park was designed from the start as a residential suburb - which is why the street grid is so regular and the housing stock is so consistent in age and style. Most homes are single-story or split-level ranch houses on standard lots, built between the 1960s and the mid-1980s. The newer Vast Oak and Willowglen neighborhoods in the southeast, developed in the 2000s and 2010s, bring a second generation of housing to the city with larger two-story homes on smaller lots.
Sonoma State University, located inside Rohnert Park's city limits, is the most prominent institution in the city and a landmark that most residents use as a geographic reference. The Green Music Center on the SSU campus hosts concerts and events throughout the year. About half of the city's housing units are owner-occupied, with the other half rented - a split that reflects the university's influence on the local rental market. Rohnert Park neighbors Santa Rosa to the north, where the region's largest city offers a wider range of commercial and medical services, and Petaluma to the south, known for its historic downtown and strong community identity.
