Scaled Site Plans for City Festival Permits
A scaled site plan is a to-scale, top-down drawing of the entire festival footprint that shows every structure, route, and safety feature in accurate proportion to the real-world space. Every object, including stages, tents, vendor stalls, portable toilets, first-aid stations, crowd areas, fencing, and emergency access lanes, appears at a consistent scale so that distances and dimensions on the page match actual ground measurements.
Municipal reviewers use the plan to verify that emergency vehicles can reach every part of the site, that crowd areas stay within capacity limits, and that sanitation and medical resources sit in the correct locations before they issue a permit.
7-Step Checklist to Draw a Permit-Ready Site Plan
You can draw your own site plan without a CAD license or an engineering degree. Follow these seven steps to create a plan that satisfies most municipal reviewers on the first submission.
-
Establish your boundary. Confirm the exact perimeter of the permitted area with your parks or public works contact. Note any fixed obstacles such as trees, hydrants, utility boxes, and existing structures.
-
Choose a scale and set up your title block. Standard plan-sheet scales can include 1″=40′, 1″=100′, and 1″=200′ depending on site size. Your title block must include the event name, site address, date, scale, north arrow, and the name of the person responsible for the plan.
-
Place emergency access lanes first. Mark every fire lane before placing any other infrastructure. Keep emergency routes clear throughout the layout process.
-
Position primary structures. Drop in stages, main tents, and grandstands. Record their footprint dimensions in feet.
-
Add vendor, sanitation, and first-aid zones. Space portable toilets and first-aid stations according to your expected attendance. Mark staffing positions on the plan as well.
-
Calculate crowd capacity for each zone. Outline every standing crowd area and calculate safe capacity based on a people-per-square-foot density. Document the figures on the plan.
-
Add your legend, north arrow, and scale bar, then export. Every element on the plan must appear in a legend. Export a high-resolution PDF at print size, with minimum A1 and A0 for large sites.
Emergency Access Lane Requirements
Emergency access lanes are non-negotiable, and fire marshals will reject a plan or shut down an event if lanes are blocked or undersized.
-
Minimum clear width. For example, California Fire Code Section 503.2.1 sets 20 ft as the baseline clear width, free of parking, vendor equipment, and landscaping. Requirements vary by jurisdiction, so confirm the minimum with your local fire marshal.
-
Vertical clearance. Ensure sufficient clearance from ground level to any overhead obstructions such as banners, cable runs, and tree canopies so emergency vehicles can pass. Because aerial ladder trucks vary in height by department and manufacturer, confirm the exact clearance requirement with your local fire marshal before finalizing overhead elements.
-
Turns and turning radius. For example, in California, turns must accommodate an 80-ft aerial ladder truck with a 55- to 65-ft turning radius. Lane width at corners must therefore increase beyond the 20 ft straight-run minimum. Turning radius requirements vary by jurisdiction and apparatus type.
-
Dead-end turnarounds. This layout should allow trucks to reverse without multi-point maneuvers, plus have local fire marshal approval.
-
Surface loading. Lanes must support the weight of emergency vehicles. Temporary grass or gravel surfaces often need a ground-protection mat specification on the plan.
-
Placement rules. As an example, some jurisdictions require that every structure sit within 150 ft of a lane access point. Run at least one emergency lane the full length of the site, and keep lanes free of temporary fencing, guy wires, and signage. Confirm exact placement rules with your local fire marshal, as requirements vary by region.
Always confirm lane specifications with your local fire marshal before finalizing the plan, because requirements vary by jurisdiction and by the apparatus your local department operates.
Exporting a Permit-Ready PDF from OnePlan
Exporting a finished plan from OnePlan takes three straightforward steps.
-
Open the export panel. Select your plan, choose PNG export, and set the output size, up to A0 for large festival sites.
-
Add your legend. OnePlan’s legend generator compiles every object on the map into a formatted key. Review it, confirm all symbols match the plan, and include it in the export.
-
Download your Bill of Quantities. Every object placed on the map saves automatically to a structured inventory. Export it to Excel or CSV and you have a complete procurement list, including the number of crowd barriers, meters of fencing, portable toilet count, and generator positions, without re-keying a single figure.
Bearfoot Productions used OnePlan’s Bill of Quantities to accurately calculate and order over 1,000 panels of Heras fencing and 1,500 pedestrian barriers, roughly 8 km of fencing total, without a separate spreadsheet. The Cheese & Chilli Festival puts it plainly: “Using OnePlan, I create accurate, detailed and professional-looking event site plans without the need for a complex CAD package.”
The finished PDF is print-ready and formatted for permit submission, contractor briefings, and event-day operations teams.
Real-World Time Savings from Eagle Mountain City
Eagle Mountain City, Utah, runs multiple community events each year. Before OnePlan, Events Manager Dawn Hancock built site plans by taking a Google Maps screenshot and importing it into Publisher, which produced non-scaled layouts and required separate maps for fire, police, facilities, and other departments.
With OnePlan, that fragmented workflow collapsed into a single, to-scale map that serves every department and stakeholder. Dawn now completes plans in a few hours instead of the previous 8–10, delivering the city a 5x return on investment. As she puts it, “Gone are the days of creating separate layouts for fire, police, facilities, and other departments. Now I can create a single, all-encompassing layout.”
The North Texas Tribute Jam had a similar experience with city approvals: “Working with the City of Lewisville’s Health and Safety Department was much simpler thanks to OnePlan. Being able to share detailed plans for roadblocks, crowd control, and traffic management meant we got the necessary approvals quickly and without headaches.”

Frequently Asked Questions
What elements must a city festival site plan include to get a permit approved?
Most municipal permitting offices require a title block with event name, address, date, scale, north arrow, and responsible party, plus a legend, clearly marked emergency access lanes (for example, California requires a minimum 20 ft clear width, though requirements vary by jurisdiction), all temporary structures with their footprint dimensions, vendor stall locations, portable toilet quantities and positions, first-aid station locations, crowd area boundaries with standing capacity figures, generator placements (for example, some jurisdictions require at least 20 ft from assembly areas, though this varies by region), and all entry and exit points with aisle widths. Requirements vary by city and state, so always confirm the exact checklist with your local permitting office or fire marshal before submitting.
Can I draw my own site plan for a festival permit, or do I need to hire a professional?
You can draw your own site plan. Most municipal permit reviewers do not require a licensed engineer or architect to produce a festival site plan, and instead require that the plan be to scale, legible, and complete. Tools like PowerPoint, Canva, or Google Maps screenshots are not to scale, so dimensions on the page do not reflect real-world measurements. OnePlan places every object on a live satellite map at true scale, so a 60 ft × 40 ft stage occupies exactly the right footprint, and the crowd capacity calculator gives you defensible figures to include on the plan. The result is a professional, permit-ready PDF that you produce yourself, without specialist software or design skills.
How does OnePlan generate a Bill of Quantities for a festival permit application?
Every object you place on the map in OnePlan, including tents, crowd barriers, portable toilets, generators, fencing, and first-aid stations, saves automatically to a structured inventory in the background. When your plan is complete, you export that inventory as an Excel or CSV file. OnePlan does the counting for you. Draw a run of crowd barriers, and it tells you exactly how many segments you need. Outline a fenced perimeter, and it returns the total length. That export doubles as a procurement list for contractors and a supporting document for your permit application, showing reviewers exactly what infrastructure is on site and where.
How long does it take to build a permit-ready site plan in OnePlan?
Most festival teams complete a working site plan in a few hours, not days. Eagle Mountain City reduced planning from 8–10 hours to a few hours per event after switching to OnePlan. SoulFest built almost its entire festival map within two days, cutting planning from two weeks at 3–4 hours a day down to one hour a day for a week. The time saving comes from working directly on a live satellite map, with no manual measuring, no re-scaling, and no separate maps for different departments, and from the drag-and-drop object library, which means you are placing accurate, labeled infrastructure from the first minute rather than drawing shapes from scratch.
