How to apply for a temporary street closure for an event

A temporary street closure can make a community event safer and easier to manage, but blocking public access requires careful coordination. In Susanville, event organizers should work with the City of Susanville Public Works Department before placing barricades, signs, booths, stages, or other equipment in the roadway.

The application process gives the city an opportunity to review traffic impacts, emergency access, pedestrian movement, parking, and the condition of streets and sidewalks. Starting early also gives organizers time to adjust the event layout if the proposed closure affects nearby residents, businesses, transit, construction, or utility work.

Requirements may vary according to the location, duration, size, and type of event. Use the city’s current forms and instructions, and contact Public Works if you are unsure whether your event needs a formal permit, an interdepartmental review, or additional approval.

Confirm that a closure is required

Begin by identifying every public area the event will use. A full road closure, partial lane restriction, parking-lane use, sidewalk obstruction, parade route, or temporary loading zone may each require a different review. A private event held entirely on private property may follow a separate process.

Check whether the affected road is maintained by the City of Susanville, Lassen County, or another agency, such as Caltrans. The responsible agency may determine where the application must be filed. If the route crosses multiple jurisdictions, allow time to coordinate with each one rather than assuming a single city approval covers the entire route.

A street closure approval does not automatically authorize amplified sound, food sales, alcohol service, temporary structures, generators, or commercial activity. Identify those activities separately and ask which departments or agencies regulate them.

Gather complete event information

A clear application helps reviewers understand the request without having to reconstruct the plan. Prepare the event name, organizer’s contact information, date, operating hours, setup and removal periods, expected attendance, and a description of the activities.

Include a map that shows the exact closure limits and all items proposed for the street. Mark stages, tents, booths, portable toilets, dumpsters, vehicles, generators, pedestrian paths, accessible routes, and emergency access lanes. Include nearby intersections and addresses so the location can be identified quickly.

The city may also need information about affected properties, notification plans, insurance, traffic control personnel, and cleanup arrangements. If the event will use water for drinking, handwashing, or cleanup, describe the source and connection method. Do not connect to a hydrant or other municipal equipment without authorization.

Design a safe traffic and pedestrian plan

The closure plan should show how vehicles, people, and emergency responders will move around the event. Consider detour routes, advance warning signs, barricade placement, parking restrictions, accessible pedestrian paths, and access to driveways and businesses. Keep intersections, fire lanes, and building entrances clear.

Use trained or qualified traffic control personnel when the layout requires active direction of vehicles or pedestrians. Signs and barricades should be visible, stable, and placed according to the approved plan. A closure that looks minor on a map can create congestion if it blocks a key intersection or leaves no practical route for deliveries.

Stormwater facilities also need protection during setup and cleanup. Keep tents, soil, trash, food waste, paint, and wash water away from drains. Reviewing how stormwater drains work can help organizers understand why materials placed near an inlet may affect streets and waterways.

Submit the request with enough lead time

Use the current City of Susanville application or instructions provided by Public Works. Submit the completed form, site map, traffic control plan, supporting documents, and any required fees or insurance information through the method specified by the city. Keep copies of everything submitted.

Allow time for review, revisions, notifications, and coordination with police, fire, utilities, parks, or other city functions when applicable. An incomplete map or missing contact information can delay review. If event details change after submission, notify the department promptly instead of relying on an informal field adjustment.

Protect utilities and surrounding property

Before installation, identify utility features and keep access available for maintenance crews. Do not cover manholes, valves, utility cabinets, hydrants, storm drains, or other infrastructure with stages, vehicles, flooring, or temporary walls. Equipment should not damage pavement, curbs, sidewalks, landscaping, or street signs.

If the event supplies temporary drinking water, use an approved connection and maintain clean dispensing equipment. Organizers should have a simple explanation ready if attendees notice air-related cloudiness after a service change or temporary connection; the city’s information on cloudy water causes provides useful background.

Plan waste collection and cleanup before the event begins. Food grease, litter, wastewater, and spilled materials should never be swept into a storm drain. Arrange for removal of all temporary equipment and leave the public right-of-way in the condition required by the approval.

Use a practical submission checklist

Before sending the request, review the package against the event plan and confirm that the onsite lead has access to the approved layout. A concise, accurate submission is easier to evaluate than a general description without a map or schedule.

• Identify the correct agency and affected streets.
• Provide setup, event, cleanup, and reopening times.
• Attach a readable site map with closures and emergency access.
• Explain detours, pedestrian routes, barricades, and traffic control.
• List temporary structures, utilities, vendors, and cleanup responsibilities.

Keep the approval and contact information available during setup and throughout the event. Conditions may require the organizer to modify a barricade, preserve access, adjust operating hours, or respond to an unexpected safety issue. The event lead should know who can make decisions and who must be contacted if conditions change.

Contact the City of Susanville Public Works Department early to obtain the current temporary closure requirements and confirm the correct submission process. Prepare the map, traffic plan, schedule, and supporting documents, then submit the complete request before advertising the closure as final.
