Town of Herndon Driveway Apron Contractor

The Herndon Protocol: Approval to Pour

The apron sits in the town right-of-way, so the work is governed by Public Works—and, in the overlay district, by the HDRB. Here is the sequence we run to get a Herndon apron permitted and built to the Town's standard:

• 1. HDRB & Zoning Approvals For property inside the Heritage Preservation Overlay District, the Heritage Preservation Review Board reviews the apron's appearance—material, texture, and color—against the town's design guidelines. We assemble the application and material samples (exposed aggregate, integral color, or a paver field chosen to suit the historic palette) and present them to the board. The HDRB meets on a fixed monthly schedule, so this step is paced by the calendar, not by us; we file early to keep it moving. That approval, a Certificate of Appropriateness, has to be in hand before work begins.
• 2. Public Works Permitting Every apron in town—overlay district or newer subdivision—needs a right-of-way permit from the Town of Herndon Department of Public Works, because the work disturbs the town-maintained street edge. We prepare the application, arrange any required bonding (an outside cost you pay at cost), and schedule the town inspections. The town sets the review window, and a right-of-way permit is a multi-week process; only the install itself is measured in days.
• 3. Utility Valve Adjustment Herndon's older infrastructure often puts a water shut-off valve or a sewer cleanout squarely inside the apron footprint. Utility-cover adjustments are done as the permit or inspector requires, and priced in your scope.
• 4. Protecting the Verge The verge is the grass strip between the sidewalk and the curb, and the town guards it. We keep excavation tight to the work, handle root protection as the permit, arborist or inspector requires (priced in your scope), and backfill and rough-grade the disturbed verge; topsoil and seed or sod can be added as a contract line item, and growing the grass in to close the permit is the owner's part (see The Tuck Standard, Sections 3C and 11).
• 5. 4,000 PSI Concrete Installation We remove the failing asphalt or old slab, install #21A crushed stone to the depth the Town's detail and permit require, compacted in lifts, and typically pour 4,000 PSI air-entrained concrete, the industry-standard mix for freeze-thaw climates (spalling is addressed in The Tuck Standard, Section 5). We reinforce the apron only where the Town's detail calls for it, and where the new slab meets any existing (cold) slab we isolate it with an expansion joint.

Historic Aprons vs. Standard Concrete

What changes when an apron falls inside Herndon's overlay district instead of a standard subdivision.

The Local Factor: Driveway Widening in Herndon

The parking pinch. Many of Herndon's older homes were built with single-car driveways on narrow streets. Widening the driveway—and the apron that feeds it—is often the only way to get a second car off the road.

The lot-coverage limit. Herndon counts driveways and parking toward its 50% impervious-coverage limit, so we measure your existing coverage before designing the expansion. If you are close to the limit, a permeable paver extension, built to the manufacturer's and ICPI typical section with final depths and overflow set by the project engineer, is designed to infiltrate stormwater on site; whether it earns any coverage credit is the Town's call, and we confirm it before design.

Outside Herndon's town limits? Permit authority changes by jurisdiction. See our Town of Vienna apron guide for the neighboring incorporated town, or our VDOT aprons in unincorporated Fairfax County page where the entrance permit is issued by VDOT rather than a local Public Works department.

What Drives the Cost of a Driveway Apron in the Town of Herndon

Herndon apron pricing depends on your zone and lot, not a flat rate. The biggest cost factors are the width and square footage of the apron, the finish required (standard 4,000 PSI concrete in a newer subdivision, or premium exposed aggregate, integral color, or paver borders in the Heritage District), and how much demolition and excavation the old apron needs.

From there, the total scales with the Public Works right-of-way permit and bonding, any Heritage Preservation Review Board (HDRB) approval in the historic zone, utility valve and cleanout adjustments common in Herndon's older infrastructure, verge restoration (topsoil and seed or sod, when line-itemed), plus any lot-coverage review or permeable extension if you are widening.
