Planning area 01Downtown Main and Market streets
The City’s Downtown Economic Development Plan treats Main and Market streets as the historic commercial core and describes a pedestrian-oriented mixed-use setting near state highways and the Sacramento River. The grid includes 300-foot blocks and narrow alleys, so access must be checked at the parcel rather than inferred from a map. A mobile commercial kitchen trailer may not fit a rear alley or downtown loading court; measure the tow combination, turns, overhead clearance and setup footprint. Confirm whether the building is within a designated historic district and whether a temporary structure, generator, service connection or sign needs City review. Keep loading clear of storefront entrances, accessible routes, fire access and other tenants. Identify a private pad, power, water, wastewater, grease disposal and food deliveries before selecting a unit. The City’s plan supports corridor and land-use context; it does not report a current downtown kitchen remodel or restaurant outage. Colusa County Environmental Health reviews food permits and inspections, and its outage guidance describes when a facility should stop food service. Ask the County how a temporary unit at a fixed business address is classified.
City of Colusa Downtown Economic Development Plan ↗Planning area 02State Routes 20 and 45 through Colusa
Colusa sits at the junction of State Routes 20 and 45, and City planning records state that highway approaches funnel through downtown. The same routes are named in the City’s emergency-planning discussion, including as possible evacuation corridors during selected incidents. That does not authorize a supplier to use an evacuation route or imply it is open during an emergency. Before planning a trailer delivery, check current Caltrans traffic controls, bridge load limits, construction notices, fire restrictions and road conditions for the specific date. Get a written receiving address and private pad from the business owner. Measure the trailer and tow vehicle as one combination, including turning space, grade, overhead wires, street parking and ability to enter and exit without backing through traffic. A truck route does not guarantee a commercial parcel can accommodate the unit. Confirm power, potable water, wastewater, grease, fire clearance and County Health review. The circulation plan offers network context rather than a delivery route, current outage notice or guarantee that Mobile Kitchen Manufacture operates in Colusa.
City of Colusa General Plan circulation element ↗Planning area 03Sacramento Riverfront and levee-adjacent parcels
The City hazard-plan annex notes that Colusa lies beside the Sacramento River and maps flood zones across parts of the city. Its 2024 FEMA map analysis reports 2,857 acres in the one-percent annual-chance flood zone and another 2,935 acres in the 0.2-percent zone; those citywide totals do not identify whether a particular business parcel is exposed. The annex also describes levee overtopping or failure as a possible evacuation trigger. For a commercial site near the river, check current parcel-level flood mapping, grading, levee and utility easements before placing equipment. Never use the levee crown, river access road, channel, floodway or parkland as a trailer pad without explicit authorization. If an actual flood occurred, have the owner confirm building, electrical, water and sewer safety before planning temporary food service. Use a firm, elevated private surface with a verified tow approach, fire access and utility connections. County Environmental Health guidance applies to food operations. This source establishes regional flood planning context, not a current warning, riverbank restaurant impact, equipment need or delivery authorization.
City of Colusa hazard-plan annex ↗Planning area 04Old Chinatown historic district near the levee
The City’s 2024 hazard-plan annex identifies the historic Chinatown district as unreinforced masonry roughly 100 feet from the Sacramento River levee and notes seasonal high-groundwater effects in underground tunnels. These are structural and subsurface conditions that should be considered before any contractor or trailer access plan is finalized. The source does not document damage to a food business. If a tenant has a confirmed renovation, the owner and engineer should determine whether the building is safe and whether ground bearing, excavation, sewer connections or equipment vibration need additional review. A mobile kitchen requires a legal private pad, stable surface, accessible staff route, fire clearance, power, potable water, wastewater and grease handling. Narrow historic streets and rear alleys can restrict towing, turning and setup; measure on site and do not block pedestrian access or emergency approaches. Colusa County Health must approve the applicable temporary food arrangement. The City’s register and mitigation annex support heritage and risk context, but they do not confirm delivery access, a current closure, local rental inventory or a Colusa rental price.
City of Colusa hazard-plan annex and historic-sites register ↗Planning area 05Colusa Weir gage and west-side drainage context
The City’s hazard annex reports that the nearby Colusa Weir gage reached flood stage during the December 1996–January 1997 event, recording 68.67 feet on January 3, 1997. During the 1995 flood, the weir and local drainages including Powell Slough and the 2047 Canal reached flood stage, inundating ground south and west of the city and contributing to disaster declarations. NOAA’s Colusa Bridge gauge provides observed river readings, but the City and County remain the source for official warnings and evacuation instructions. A gauge reading is not a site-specific flood determination. For a food facility in the west or south drainage area, check road status, levee conditions, site elevation, utility service and floodwater contamination before planning a temporary kitchen. Do not move equipment onto a levee, access road or low agricultural parcel without property and agency approval. Confirm that the receiving lot is firm, elevated and outside emergency access. These records document historical hydrology, not a current emergency or a restaurant closure. No supplier route or service availability is confirmed.
City of Colusa hazard-plan annex and NOAA river gauge ↗Planning area 06Harris Street and Sixth Street storm-drain area
In its August 2024 annex, Colusa describes an underground storm-drain project at Harris Street and Sixth Street as bid and beginning construction at that time. The City said the drainage repairs had produced visible improvements, but the dated passage does not show whether work remains active today. Check the current Public Works notices before planning access near this intersection. If a food business is undergoing a separate documented kitchen remodel, identify the property’s receiving pad outside trench limits, catch basins, utility boxes and traffic-control areas. Confirm stormwater separation so cooking, wash and wastewater never flow to a street drain. Measure the full tow path and trailer footprint and verify safe turns, overhead clearance, hardstand, fire access and utility connections. The City hazard plan links this drain project to mitigation, not to a restaurant outage or a temporary-food contract. County Environmental Health permits food facilities and can advise how a temporary mobile kitchen at a fixed address is reviewed. The planning reference is specific to drainage infrastructure; it does not prove a kitchen shutdown, current road closure, rental need or local equipment availability.
City of Colusa hazard-plan annex ↗Planning area 07Bridge Street between Main Street and Wescott Road
The City’s August 2024 hazard annex describes a partnership with Caltrans to install two 48-inch storm-drain pipes across Bridge Street between Main Street and Wescott Road. The record reflects an infrastructure mitigation effort and does not provide today’s traffic-control status or prove a particular business was affected. Before arranging a mobile kitchen trailer nearby, confirm whether the receiving property is inside current work limits and ask Public Works for the latest access information. Do not treat a state-highway shoulder, drainage structure or construction staging area as a delivery pad. On private property, check grade, pavement strength, turning radius, gate width, overhead clearance, fire access and room for staff, steps, food delivery and connections. Plan sanitary wastewater and grease disposal separately from storm drainage. If the permanent kitchen is down, document the closure reason, dates, menu and County Health approvals. A drainage project may inform route planning, but it does not establish a kitchen renovation, outage, service contract, price or authorized supplier route.
City of Colusa hazard-plan annex ↗Planning area 08Wescott Road realignment and southbound approach
The City’s Public Notices page lists a permanent traffic-change notice for the Wescott Road Realignment Project, posted in 2026. The notice is a reason to verify the current intersection layout and approach before sending an oversized trailer; a general map or prior driving route may no longer be reliable. The notice itself does not establish that a local food facility is closed or that all surrounding streets are under construction. Ask the business owner and City Public Works for the authorized driveway, turning path, traffic-control information and delivery window. Confirm the tow combination’s length, width, height, braking and swept turn, plus pavement, overhead lines, utility clearances and fire access. Keep setup inside the permitted private parcel and away from drainage infrastructure. For food use, verify power, potable water, wastewater, grease, handwashing and County inspection requirements. Public notices change; recheck them close to the date of transport. This location-specific planning point supports safe arrival coordination, not an approved commercial dispatch route or a promise of Colusa service coverage.
City of Colusa Public Notices ↗Planning area 09Southern Colusa multi-year road-repair area
In June 2024, the City announced that it had awarded a bid for Phase 1 of its multi-year road-repair and repaving program. The release says the phase covered selected roads on the southern end of the city using rubberized asphalt and that schedules and closures would be communicated separately. It does not identify a current closure or establish the status of later phases, so check the public notice page before choosing a delivery date. A nearby food operator should verify whether its driveway, loading space, sidewalk, storm drain or business access is affected by active road work. Keep a trailer on an owner-approved private surface, not on newly paved pavement without permission or inside a work zone. Confirm tow clearance, pavement capacity, turning room, overhead wires, fire access, utilities and sanitary hookups. County food plan review is separate from public road work. The 2024 press release documents the bid award and general area; it does not show a restaurant outage, active kitchen remodel, delivery promise or local rental price.
City of Colusa Phase 1 road-repair press release ↗Planning area 10Wastewater treatment plant and sewer collection system
Colusa’s hazard-plan annex records that flood events in 1998, 2006 and 2017 inundated the wastewater treatment plant and sewer collection facilities, resulting in sanitary sewer overflows onto public streets. Those are historical system impacts; the annex says post-2019 flooding has been localized without significant property damage. The City’s current bid page publishes documents for a Sewer and Recycled Water Project, but does not state that a customer sewer interruption is underway. For a restaurant or institutional facility, verify sewer availability and the exact utility schedule with the City before planning a temporary kitchen. A rental trailer does not resolve unsafe wastewater service; wastewater storage, removal and approved disposal must be settled before operation. Keep equipment outside plant property, flood areas, easements and maintenance roads. Confirm site drainage, electrical supply, potable water, handwashing, grease, ventilation, fire clearance and food inspection dates. The County Health Department’s food-safety guidance applies during utility and power interruptions. This entry is operational context, not a claim of a present sewage event, food closure or equipment dispatch to a City facility.
City of Colusa hazard-plan annex and utility records ↗Planning area 11Sixth Street trunk sewer from Parkhill to Ninth and Harris
The City’s sewer master plan identifies a shallow 6th Street trunk sewer from around Third and Parkhill streets to Ninth and Harris streets. Its 2009 engineering analysis says modeled wet-weather flows and downstream pump-station limitations can cause surcharge concerns and recommends condition assessment and cleaning before finalizing capital work. This older master plan is infrastructure context, not a current sewer-service notice or a claim that the trunk is failing today. If a commercial kitchen near this corridor is being remodeled, ask the City utility team to confirm the parcel’s current service, interceptor requirements and any construction schedule. A trailer needs a lawful wastewater strategy sized to menu, meal volume and cleaning. Do not connect to a manhole or alley sewer without utility authorization, and never discharge to storm drains. Secure a stable private pad with room for the trailer, tow rig, fire access and service connections. San Bernardino/Colusa food permitting is handled by Colusa County Environmental Health. Recheck current sewer and road notices before booking; historical modeling cannot substitute for a current inspection or local approval.
City of Colusa Wastewater Collection System Master Plan ↗Planning area 12Will S. Green Pump Station bid area
The City’s Open RFPs and Bids page currently lists a Will S. Green Pump Station bid package, with contract documents, technical specifications, drawings, geotechnical material and electrical sheets. The posting establishes that bid documents are available; the page does not establish a construction start, work limits or water/sewer impact on a nearby business. Confirm procurement and construction status with the City before assuming a project is active. No food service should be staged at the pump station or on utility property without written agency authorization. For a commercial kitchen renovation nearby, ask the owner for the actual pad and the City for any planned service interruption. Check truck access, turning geometry, overhead clearance, pavement, fire lanes, sanitary sewer capacity, water pressure, electrical load and site drainage. A mobile kitchen needs separate food-safety and utility approval. County Environmental Health distinguishes retail food facility review from mobile food facility applications; ask how a fixed-location trailer is classified. The bid package is infrastructure planning context, not a current customer outage or a promise that Mobile Kitchen Manufacture can deliver to this location.
City of Colusa Open RFPs and Bids ↗Planning area 13City Wells Project and water-system reliability
The City’s open-bids page currently publishes the 25-105 Colusa Wells Project bid package and addenda. The Utilities page describes City operation of water pumping, treatment and distribution, and sewer collection and treatment; its public notice archive also contains a 2025 update about a lightning-related surge affecting water-system radio communications. In that notice, staff manually operated the system while repairs proceeded and the City said temporary lower pressure could occur as tanks refilled. It did not describe a restaurant closure or complete water outage. For a food operator who reports a current service problem, call the utility to confirm pressure, quality, shutoff and boil-water status at the exact address. Temporary cooking equipment requires safe potable water, handwashing and an approved wastewater route. A trailer cannot replace utility confirmation. If the parcel is close to a well or pumping facility, verify its private access and keep equipment out of operational yards and easements. County Health guidance covers food handling during temporary power outages. The bid page and past notice are not evidence of current work, local kitchen need or available rental service.
City of Colusa Open Bids and Utilities ↗Planning area 14City Hall and County civic core around Webster and Market
The City identifies its former Colusa Grammar School, now City Hall, at 425 Webster Street as a historic landmark, and the County courthouse at 547 Market Street as a state landmark. Civic offices are not default receiving points for commercial kitchen equipment. If an authorized public event or municipal project requires food service, obtain a written site assignment, designated event manager, property permission, utility instructions and current fire and Health permits. Do not deliver equipment to government parking or block public access, accessible spaces, emergency exits or responder routes. For private businesses in the civic core, confirm whether the structure has preservation review requirements before attaching temporary utilities or placing a generator. Measure the path through narrow urban streets and alleys, including turning radius, overhead lines, pavement, loading hours and room to set up. Colusa County Environmental Health oversees food permits and inspections, while City Planning and Building reviews land use and construction matters. Landmark status helps explain why site changes need coordination; it does not indicate an active food renovation, outage, delivery approval, equipment stock or Colusa-specific price.
City of Colusa historic-sites register ↗Planning area 15Colusa State Recreation Area and Roberts Road edge
The City’s hazard-plan annex records that the 2021 Jungle Fire burned about 30 acres, primarily in the riparian area of Colusa State Recreation Area, with limited spread toward private property near Roberts Road. It does not record damage to a restaurant or the need for temporary cooking equipment. The City Fire Department describes fire response operations within city limits, but state park access and incident control may involve other agencies. Do not route or stage a trailer in a park, fire perimeter, evacuation area, levee or riparian access road without written authorization from the managing agency and incident command. For an approved private event or nearby food-business remodel, confirm property access, current fire restrictions, gate clearance, vehicle turning, surface bearing, overhead obstructions, water and wastewater. Protect storm drains and habitat from food waste, grease and washwater. Ask County Environmental Health which event or food-facility permit is required. The documented fire is dated context; it is not a current hazard warning, commercial closure, delivery route, local service confirmation or guarantee of equipment availability in Colusa.
