Question 1

Does my Glen Ridge driveway or walkway project need a Certificate of Appropriateness from the HPC?

Accepted Answer

Probably yes, if the work involves any surface or structure visible from the street and your property is a contributing resource in the Historic District — which covers over 90 percent of the borough. The Glen Ridge Historic Preservation Commission reviews exterior changes including paving, front walkways, boundary walls, and masonry repairs. Applications are submitted at least 20 days before the HPC's monthly meeting. Separately, driveway aprons and any work within the public right-of-way typically require a building or DPW permit from the borough. We handle both processes as part of the project so you don't have to coordinate them on your own.

Question 2

What paving materials are appropriate for a historic home in Glen Ridge?

Accepted Answer

The most common and historically compatible choices are asphalt driveways framed with Belgian block curbing, bluestone or brick walkways, and natural or tumbled-stone paver patios. The Glen Ridge HPC design guidelines favor materials that match the character of the pre-war streetscape, so bold decorative stamped concrete or brightly colored pavers are generally not the right fit. For repointing masonry, the mortar type must be softer than the existing brick — a lime-rich Type N or Type O mortar rather than modern high-strength portland-cement mixes, which can damage historic masonry. We will recommend materials that suit your home's era, meet HPC expectations, and hold up through New Jersey winters.

Question 3

My Glen Ridge home has water pooling near the foundation after rain. Can new paving fix that?

Accepted Answer

New paving alone will not fix a drainage problem, and installing it over saturated ground without correcting the drainage first accelerates failure. Glen Ridge's clay-rich soil does not drain quickly, and low spots near Toney's Brook can see groundwater pressure against foundations after extended rain. We assess the full drainage path before recommending a solution — which might involve regrading, a French drain or catch basin, corrections to downspout routing, or a retaining wall with integrated drainage. Getting the water moving correctly protects both the new paving surface and the foundation it sits next to.

Question 4

How long does a properly built asphalt driveway last in Glen Ridge?

Accepted Answer

A driveway built on a sound 4- to 6-inch compacted aggregate base with properly applied hot-mix asphalt should last 20 to 30 years in New Jersey. The variables that shorten that lifespan most are poor drainage (water under asphalt freezes, expands, and causes frost heave) and unsupported edges that crumble inward over time. Sealcoating helps: wait 6 to 12 months after installation before the first application, then reseal every 2 to 3 years to slow oxidation and water intrusion. Many driveways we replace in Glen Ridge were installed with an inadequate base and failed in 8 to 12 years — a correctly built installation is noticeably different in longevity.
