Surrey Driveway Widening Site Plan for Permit

Widening a driveway can provide more convenient parking, easier vehicle access, and additional room for entering or leaving a residential property. However, the work may involve more than simply adding concrete, asphalt, or paving stones beside the existing driveway.

In Surrey, a driveway-widening project may affect the driveway crossing, curb, sidewalk, boulevard, drainage, trees, utilities, and access to the property. A clear Surrey driveway widening site plan for permit helps the City understand exactly what exists now, what will change, and how the completed driveway will connect safely to the street.

Do You Need a Permit to Widen a Driveway in Surrey?

Generally, yes. The City of Surrey states that a driveway permit is required when constructing a driveway or adding to an existing driveway. A permit may also be required when part or all of an existing driveway is being demolished or replaced.^[1]

The permit process allows City staff to review how the proposed driveway connects to the public street and whether the work may affect:

• the curb or driveway letdown
• the public sidewalk
• the boulevard between the property and street
• roadside drainage or an open ditch
• street trees and trees on private property
• utility infrastructure
• vehicle and pedestrian visibility
• the slope between the road and private property

Requirements can differ depending on the property, road type, existing frontage, zoning, nearby trees, and whether the lot is served by a curb-and-gutter system or an open drainage ditch. Before finalizing the drawing, homeowners should confirm the latest requirements with the City for their particular address.

What Is a Driveway Crossover?

The terms driveway crossover and driveway crossing generally describe the portion of the vehicle access located between the private property and the road.

Depending on the street, this area may cross:

• a sidewalk
• a landscaped boulevard
• a curb and gutter
• a roadside drainage ditch
• a culvert beneath the driveway

The driveway inside the property and the crossing within the public frontage are related, but they are not always treated as the same element. Widening the paved area on private property does not automatically mean that the street crossing can be widened to the same dimension.

The site plan should therefore label and dimension both areas separately:

• Existing driveway width within the property
• Proposed total driveway width after widening
• Existing driveway-crossing width at the street
• Proposed driveway-crossing width, where it will change

This distinction helps reviewers understand whether the proposal affects only private paving or also requires changes to the curb, sidewalk, boulevard, ditch, or culvert.

What Should a Surrey Driveway Widening Site Plan Show?

A good driveway-widening plan should give the reviewer a complete top-down view of the property and street frontage. It should clearly distinguish existing conditions from proposed work.

1. Property Lines and Lot Dimensions

The site plan should show the available property boundaries, lot width, lot depth, street frontage, and any irregular property-line dimensions.

These boundaries help establish whether the proposed widening remains on the owner’s property and whether any paving, retaining work, or landscaping extends into a public right-of-way or neighbouring parcel.

When the legal boundary is uncertain, the project is close to a lot line, or precise boundary verification is required, the City may request a legal survey. A drafted site plan does not replace a survey when legal boundary confirmation is necessary. Our site plan versus survey guide explains when each type of document may be needed.

2. Existing House, Garage, and Other Structures

The drawing should show the footprint of the existing house, attached or detached garage, carport, stairs, porch, retaining walls, fences, and other structures near the driveway.

These details help the reviewer see how vehicles currently enter the property and whether widening the driveway will affect access to the garage, front entrance, side yard, or other improvements.

Properties where the driveway serves a detached garage may also benefit from reviewing our Surrey garage site plan guide, which discusses driveway and lane access in more detail.

3. Existing and Proposed Driveway

The existing driveway and proposed widened area should be visually different and clearly labelled. The plan should normally include:

• existing driveway length and width
• dimensions of the proposed widening
• total driveway width after construction
• driveway surface material, when relevant
• distance from the driveway to property lines
• distance from nearby buildings and structures
• location of the garage, carport, or parking area served by the driveway

The proposed work should not appear as an unlabeled patch of pavement. A reviewer should be able to identify the limits of construction immediately.

4. Driveway Crossing, Curb, and Sidewalk

The plan should identify the point where vehicles cross from the street onto the property. Depending on existing conditions, it may need to show:

• edge of pavement or curb
• curb-and-gutter location
• existing curb letdown
• proposed curb or crossing changes
• sidewalk location and width
• boulevard width
• existing and proposed crossing widths
• distance to the side property lines
• distance to nearby intersections or other driveways, where relevant

Changes within the public road allowance may require City approval and may need to be completed according to municipal construction standards. The property owner should not assume that private paving work automatically authorizes alterations to a curb, sidewalk, boulevard, or drainage system.

5. Vehicle Access and Manoeuvring Space

A wider driveway must still provide practical access. The plan should make it clear how vehicles will move between the road, driveway, parking area, garage, or carport.

Reviewers may need to understand whether the proposal:

• maintains clear access to the garage
• provides sufficient room to enter the property
• avoids trapping vehicles behind one another
• keeps walkways and entrances accessible
• maintains appropriate visibility near the street
• avoids conflicts with fences, gates, trees, and utility equipment

Showing the complete access route is particularly important when the property has an unusual lot shape, a steep approach, a corner location, a narrow frontage, or more than one parking area.

Our guide explaining what to include on a building-permit site plan provides a wider checklist for driveways, access points, structures, and setbacks.

Driveway Grade and Slope

The difference in elevation between the road and the property can affect whether a vehicle can enter without scraping or becoming caught at a change in slope.

Current City of Surrey driveway guidance states that, for a minimum distance of 6 metres within private property, the driveway grade should generally be no more than 5% to reduce the risk of vehicles “hanging up” or bottoming out.^[1]

The exact information needed on the plan will depend on the site. A relatively flat property may only need basic slope or grade information, while a steep or complex property may require:

• existing and proposed elevations
• grade percentages
• slope arrows
• curb and road elevations
• garage-floor elevation
• retaining-wall information
• a grading plan prepared by a qualified professional

A site plan should not invent elevations that have not been measured. Where accurate grades are important to the design, a topographical survey or professional grading information may be required.

Drainage Considerations for a Widened Driveway

Driveways are usually made from relatively impermeable materials. When the paved area becomes larger, the amount and direction of surface runoff may change.

That is why the site plan may need to show how water will move across the proposed driveway. Depending on the project, drainage information may include:

• existing and proposed slope directions
• drainage-flow arrows
• roadside gutter or ditch
• existing catch basin or lawn basin
• trench drain or channel drain
• drainage swale
• permeable or porous paving area
• culvert beneath the driveway crossing
• areas where runoff enters the municipal system

The City identifies porous driveways, drainage swales, perforated pipes, rock pits, and other features as possible components of sustainable residential drainage.^[2] However, the appropriate solution depends on the property and should be confirmed before construction.

The plan should avoid suggesting that runoff will simply be directed toward a neighbouring property, building foundation, sidewalk, or another area where it could create a drainage problem.

Properties With an Open Ditch or Driveway Culvert

Some Surrey properties have an open drainage ditch along the street rather than a standard curb-and-gutter frontage. In these locations, widening the driveway crossing may affect the culvert beneath it.

The City explains that ditches form an important part of Surrey’s drainage system and allow stormwater to infiltrate into the ground. Its driveway-culvert process begins with a permit application and a site plan showing the proposed crossing location.^[3]

A pre-construction survey may also be required to document features such as:

• ditch invert elevations
• existing culvert size, material, depth, and length
• culvert inlet and outlet locations
• nearby trees
• utility poles
• catch basins and manholes
• other service connections near the crossing

City staff may inspect the location and determine the required culvert and construction details. Additional inspections can be required during installation, including before the culvert is backfilled.^[3]

Because of these extra requirements, homeowners with a roadside ditch should confirm the culvert process before ordering materials or beginning excavation.

Trees, Landscaping, and Utilities

A proposed driveway should not be designed without considering existing trees and infrastructure.

The City’s driveway guidance states that driveways must be located outside the drip line of trees and notes that consultation with an arborist may be required.^[1]

A permit site plan may therefore need to identify:

• tree trunks and approximate canopy or drip lines
• street trees and trees on private property
• utility poles and guy wires
• fire hydrants
• catch basins
• electrical or communications boxes
• water, storm, and sanitary service locations when known
• retaining walls, fences, and gates

Showing these features early can help identify conflicts before the driveway design is submitted or construction begins.

Surrey Driveway Permit Drawing Format

The City’s driveway-permit instructions call for a good-quality, scaled drawing prepared in metric units, using a scale of 1:500 for the application described on its driveway-permit page.^[1]

The drawing should be clean, legible, and organized. It should normally include:

• property address
• applicant or owner information where required
• north arrow
• drawing scale
• property boundaries
• street name
• existing conditions
• proposed driveway widening
• measurements in metric units
• clear notes and labels

Applicants should always check whether the City has requested a different scale, additional engineering information, or supplementary documents for the specific property.

Common Driveway Site Plan Mistakes

Permit review can be delayed when the drawing leaves important questions unanswered. Common problems include:

• showing only the proposed driveway without existing conditions
• failing to distinguish the driveway from the driveway crossing
• missing existing and proposed widths
• not showing the curb, sidewalk, boulevard, ditch, or culvert
• omitting property lines or lot dimensions
• not showing nearby trees or utilities
• leaving out drainage direction
• using unclear aerial imagery without dimensions
• providing an unreadable or unscaled sketch
• showing paving that appears to extend onto neighbouring or public land
• not matching the site plan to the actual work proposed

A clear plan does not guarantee permit approval, but it can reduce avoidable questions by giving the reviewer the measurements and site context needed to assess the proposal.

When Might You Need a Survey or Engineer?

A standard permit site plan may be suitable for many residential driveway projects, but additional professional information may be required when:

• the property boundary cannot be confirmed
• the driveway is very close to a lot line
• the site has a steep or complicated slope
• retaining walls are proposed
• the driveway affects a ditch or culvert
• significant grading or fill is required
• stormwater controls must be designed
• utilities may be affected
• the City requests certified elevations or engineering

SitePlans.ca can prepare a clear permit-focused drawing, but a drafted site plan is not a replacement for a British Columbia land surveyor, civil engineer, geotechnical engineer, arborist, or other professional when the City requires their services.

What Information Should You Provide?

To prepare a driveway-widening site plan, it is helpful to provide:

• the Surrey property address
• an existing survey or previous site plan, if available
• the existing driveway width and length
• the proposed widening dimensions
• the desired total driveway width
• photos of the driveway and street frontage
• photos showing the curb, sidewalk, boulevard, or ditch
• a rough sketch showing which side will be widened
• garage or parking-space dimensions
• known tree, utility, drainage, or easement information
• City permit comments, if the application has already been reviewed

The more clearly the proposed work is explained, the easier it is to prepare a drawing that reflects the actual project.
