Rohnert Park, CA
Which restoration company covers Rohnert Park?
RestoreX does, from our main office on Lakeville Street in Petaluma, about 10 road miles south of City Hall on Avram Avenue. We trace where a leak or overflow traveled with moisture readings, dry it, pull out ruined drywall, flooring or cabinets, clean up sewage and rebuild, in houses, apartments and mobile homes.
Rohnert Park was planned before it was built. Only four adults lived in the district in 1956, when layout of the old Rohnert Seed Farm began, and the city incorporated in 1962. East of US 101 the neighborhoods are lettered sections, where most street and park names start with the section’s letter. Census Bureau estimates for 2020 to 2024 put the median home at 1982, a few years newer than in Petaluma or Santa Rosa. About half of occupied homes are rented, so water damage here often involves both a tenant and an owner.

About Rohnert Park
Where does storm water collect in Rohnert Park?
Along its channels and the low roads on the west edge. Copeland, Hinebaugh, Crane and Five creeks all run in engineered channels, alongside built runoff channels such as Wilfred and Labath, and the Laguna de Santa Rosa forms part of the border with Cotati. Rohnert Park Expressway near Stony Point Road has flooded in several recent storms.
The worst recent storms show the pattern. On December 15, 2016, Copeland Creek reached its highest peak on the USGS gauge, 672 cubic feet per second, and up to 4 feet of water stood on the road near Rohnert Park Expressway and Stony Point Road. During the October 2021 atmospheric river, the ‘Rohnert Park 0.9 SW’ gauge logged 9.19 inches in 48 hours, the highest Sonoma County total in that National Weather Service report (NWS rainfall report). The expressway was closed for flooding in January 2023 and again in November 2024, and Labath Avenue near the 6100 block has repeat flooding reports from 2017 to 2025.
Sonoma Water maintains most of the city’s ditches and built channels as its Zone 1A, and the city’s storm drains are separate from the sewer, carrying runoff untreated to the creeks (Rohnert Park flood control maps). FEMA’s current map, effective July 19, 2022, shows Zone AE with a floodway, shallow-flooding Zone AO and Zone A, but no levees, and the city is not in the Community Rating System. With a strong El Niño forecast for 2026-27, the city is handing out sand and bags at no charge at its filling station and runs a non-emergency storm line, 707-588-3307.
Sewers are the other half of the picture. Most of the city’s 100 miles of gravity sewer went in between 1956 and 1980, and the wastewater travels about 7 miles west to Santa Rosa’s subregional plant on Llano Road. Flows that average 3.5 million gallons a day in dry weather can reach 15 million in winter, and the city names storm inflow, rags, roots and grease as common causes of overflows.
Permits & rebuilding
How strict is Rohnert Park about permits for repairs?
Strict. The city requires a building permit for any alteration, repair or demolition of a building, reroofs included, and only a licensed California contractor or the legal owner can get one. A first plan review typically takes 29 days, resubmittals 20, and permits stay valid for one year. Flood hazard areas also need a development permit.
Rohnert Park: line these up before repairs
- Call the Building Division at 707-588-2240, or visit the 2nd floor of 130 Avram Avenue, to confirm which permits your repair needs.
- Expect plans to be routed to whichever departments apply, from Planning, Engineering and Fire to Santa Rosa Industrial Waste and Rohnert Park Disposal.
- Restoration costing 50% or more of the building’s pre-damage market value is substantial damage under Municipal Code 15.48.050.
- After a lateral overflow reaches public or neighboring property, the owner must have the lateral inspected, then repaired or replaced if it’s defective, with testing done by a state-licensed contractor.
- Keep any certificate of building sewer compliance on file, since the city treats it as valid for 15 years.
Services in Rohnert Park
What water problems does RestoreX fix in Rohnert Park homes and apartments?
Leaking supply lines, failed water heaters and sewage overflows from roots or grease in a lateral, along with storm water near the channels. In apartment buildings we also check the units beside and below the leak. Mobile homes get checked underneath as well as inside, and mold comes out wherever drying started too late.
FAQ
Rohnert Park Questions
Does Rohnert Park require a lateral inspection when a home sells?
Not under the city’s sewer lateral chapter, which has no point-of-sale rule. Municipal Code 13.26.045 ties inspections to events instead: an overflow that reaches public or neighboring property, a new structure on a lot with an existing lateral, connecting a structure for the first time, a change from residential to commercial or restaurant use, or a conversion to a common-interest development.
Who maintains the sewer line from a Rohnert Park home to the main?
The owner does. Municipal Code 13.26.030 puts the whole sewer service lateral, both the building sewer and the street lateral, on the owner, who must keep it clear of roots and grease and repair or replace a defective building sewer. When a lateral backs up into the house, our sewage cleanup crew can remove the mess and disinfect.
Where does Rohnert Park get its water?
From two sources. The city is its own retail water provider, and about 65% of the supply is treated Russian River water from Sonoma Water, which runs the 18-mile Petaluma Aqueduct that serves the city; another city page puts that share at 70%. The rest is pumped from 30 deep city wells, and seven storage tanks hold about 5 million gallons.
How old are the homes in Rohnert Park?
The median one dates to 1982, and 43% of units were built before 1980. Newer growth comes through specific plans such as the University District, about 300 acres and 1,665 homes adopted in 2006, and the Southeast plan of 2010, about 80 acres with up to 499 homes. Mobile homes are about 5% of housing, and a falling tree hit one on Rancho Verde Circle in January 2021.
