Orlando Driveway Widening Site Plan: Property Lines, Drainage and Impervious Coverage

Widening your driveway can make parking easier and give vehicles more room. Before adding concrete or pavers, check how the extra pavement fits within your property and affects drainage.

An Orlando driveway widening site plan shows the existing driveway, proposed addition, property boundaries and important dimensions. It helps explain the work, but Orlando may also require a survey and professional drainage documents as part of the application.

The best starting point is a clear layout supported by accurate property information.

Does Driveway Widening Require a Permit in Orlando?

Yes. Orlando’s Engineering Permit Guide states that expanding a driveway requires an engineering permit application. The same guidance covers installing or removing pavers, asphalt and concrete. Work associated with building construction follows the applicable building permit process. [1]

First, confirm that your property is within the City of Orlando’s jurisdiction. An Orlando mailing address does not necessarily mean the city handles your permit.

Describe the full project when checking requirements. Explain whether you are adding a strip beside the existing driveway, replacing pavement, changing elevations or modifying the connection to the street.

Do not assume that a small paved addition is exempt simply because the house and garage remain unchanged.

Start with Property Lines and Easements

Before choosing the new driveway edge, collect your existing survey and relevant recorded documents. Check the legal boundary, easements and the relationship between your driveway, sidewalk and street.

Orlando’s driveway guidance describes using a signed and sealed survey showing property lines and easements. If you cannot locate one, the city suggests requesting its records and contacting a surveyor if no suitable copy is available or the survey is outdated. [2]

A fence, hedge or grass edge should not be treated as proof of the legal boundary. Resolve uncertain property information before designing close to a neighboring lot.

Our guide to site plans versus surveys explains the difference between showing a proposed project and professionally verifying the property information.

Show Existing Pavement and Proposed Widening Separately

A reviewer should be able to identify the proposed work immediately. Use separate shading, line styles or labels for the existing driveway and the added pavement.

Orlando’s residential site engineering checklist calls for a clear distinction between existing features that will remain and proposed improvements. It also requests relevant dimensions, including the pavement edge’s distance from the property line. [3]

Make these measurements easy to find:

• The existing driveway width.
• The width and length of the proposed addition.
• The total driveway width after widening.
• The distance from the proposed pavement edge to the relevant property line.
• Any changes near the sidewalk or driveway apron.

Show curves and irregular sections clearly. A single width dimension may not explain a driveway that becomes wider toward the garage or street.

Orlando directs applicants to Municipal Code Section 61.302 for driveway width, semicircular driveway and material requirements. Confirm the applicable standards before finalizing the design. [2]

Calculate Impervious Coverage Before Adding Pavement

Impervious coverage describes surfaces that prevent water from soaking into the ground. Orlando’s Impervious Surface Ratio worksheet includes concrete, pavers and buildings, along with artificial grass, gravel and rock gardens. [4]

Do not calculate only the new driveway strip. Review the existing surfaces and the completed proposal together, using the city’s worksheet.

The worksheet identifies the following limits:

Confirm the zoning and applicable limits for your property. The worksheet requires submission with the site plan through ProjectDox. [4]

A Simple Coverage Example

For illustration, suppose a lot contains 6,000 square feet and its existing counted impervious surfaces total 2,700 square feet. Adding 180 square feet of driveway produces 2,880 square feet, or 48% total lot coverage.

That arithmetic does not establish approval. You must also calculate the front yard separately and confirm the correct boundaries, counted surfaces and applicable standards.

Drainage Requires More Than Arrows on a Drawing

Driveway widening can change how rainwater moves across the site. New pavement may cover an existing drainage route or change the relationship between the driveway and neighboring ground.

Orlando’s driveway guidance states that increasing impervious area or altering existing elevations or surface drainage patterns requires a professional engineer’s grading plan and stormwater calculations, together with a professional surveyor’s topographic survey. [2]

Because widening commonly adds impervious area, address these requirements before assuming a basic layout drawing completes the submission.

The city’s engineering checklist also addresses protecting neighboring properties from increased or concentrated runoff and from water being impounded by the proposed work. [3]

Useful questions for your drainage professional include:

• Where does water flow before construction?
• Will the widening interfere with a swale or low area?
• Will the new surface change runoff toward neighboring land?
• What grading or stormwater measures are needed?

Conceptual arrows can explain an idea. Measured elevations and professional calculations establish the drainage design.

Check the Driveway Apron and Public Sidewalk

The driveway inside your lot and its street connection need to work together.

Orlando describes the apron as the area between the street and sidewalk and requires it to match the driveway width. Apron work requires the city’s maintenance-of-traffic notes and driveway detail sheet. Pavers on an apron also require a notarized paver agreement. [2]

Show whether the project changes the apron, curb connection or sidewalk crossing. Do not leave those areas out of the drawing when they are part of the proposed work.

Practical Site Plan Checklist

Use this checklist to organize the layout, then coordinate it with the city’s engineering requirements and your professional documents.

Prepare the Application Before Scheduling Construction

1. Confirm jurisdiction and zoning. Establish which rules apply to the property.
2. Collect property records. Locate a suitable survey and easement information.
3. Develop the layout. Show the complete widening and street connection.
4. Calculate coverage. Check both the lot and front yard.
5. Coordinate professional documents. Resolve survey, grading and stormwater requirements.
6. Submit the permit package. Follow the city’s application and digital upload instructions.

Plan inspections with your contractor. Orlando’s Engineering Permit Guide identifies a sidewalk, curb and driveway inspection before concrete is poured, followed by a final inspection. [1]

Frequently Asked Questions

Can I use pavers to avoid impervious coverage limits?

Do not assume so. Orlando includes pavers in its impervious-surface guidance. Confirm how the proposed paving system will be treated before calculating coverage. [4]

Is staying below the total lot limit enough?

No. The city also requires a front-yard ISR check. Both calculations need to use the applicable areas and standards.

Can a basic site plan replace the required survey?

No. A basic drawing does not replace a required signed and sealed survey or professional drainage documents.

Will ordering a site plan guarantee approval?

No. Approval depends on the proposed design, applicable requirements and complete submission.
