In Monmouth County, from the Red Bank peninsula to the farm townships around Freehold, a resin-bound surface can count as stormwater infrastructure only as the top of a full pervious paving section, and only if the municipal engineer accepts it as an alternative to the surfaces the state manual names. The section needs open-graded stone below the surface and either infiltration or an underdrain beneath that; along the bays, rivers and ocean, the seasonal water table usually decides which.

Your municipality applies the state stormwater rules through its own ordinance, and the county adds its own drainage review when a site touches a county road or drainage system. Pouring resin-bound over an existing Monmouth driveway or patio slab is a different job: rain passes through the new finish, meets the old concrete and runs off just as it did before, so nobody should claim it as stormwater control.

Municipal ordinances, the state rules and the county's drainage check

Each of the county's municipalities enforces a stormwater control ordinance built on N.J.A.C. 7:8. The state thresholds for major development are one acre of disturbance or a quarter acre of new regulated impervious or motor vehicle surface. Since January 20, 2026, the state definition also counts reconstructing a quarter acre of either surface; towns must add that to their own ordinances, so ask your municipal engineer whether yours has. Those projects have to meet the state's recharge, water quality and quantity standards that apply to them using green infrastructure, a list that includes pervious paving systems. Recharge is not required on previously developed land in an urban redevelopment area, and the quality standard depends on how much motor vehicle surface is involved.

The county layer is specific. Its Development Review Committee looks at site plans and subdivisions touching county roads, drainage facilities or county land, and it wants a sealed drainage analysis that runs the 25-year storm whenever a site has an acre or more of impervious surface, ties into county drainage, or adds 5,000 square feet or more of impervious surface along a county road that drains toward the road. New procedural regulations took effect August 1, 2026.

Sandy soils, shallow groundwater and the shore

Monmouth sits on the Coastal Plain, and many sites have sandy soils that take water readily. The limit is usually groundwater, which rises toward the Navesink and Shrewsbury rivers, Raritan and Sandy Hook bays, and the ocean-front towns. N.J.A.C. 7:8 wants 2 feet of separation from the bottom of an infiltrating pervious bed down to the seasonal high water table, reduced to 1 foot when the bed has an underdrain. Coastal flood zones, tidal backwater on outfalls and CAFRA permits can all shape the outlet.

The pervious paving chapter of the state BMP Manual keeps the paved surface at or below a 5 percent slope, asks for the stone bed to empty within 72 hours, and allows run-on from no more than three times the paved footprint. Because that chapter lists only porous asphalt, pervious concrete and permeable pavers, a resin-bound course goes to the municipal engineer as an alternative measure under N.J.A.C. 7:8-5.2(g). Beneath it, your engineer can call for open-graded stone, Rock Crete or a different permeable base.

Typical Monmouth projects

Shore-town driveways, walkways and courtyards in places like Red Bank, Long Branch and Asbury Park, where lots are small and grade is flat.
Restaurant patios and hospitality courtyards along the bays and rivers, designed with underdrains where groundwater is high.
Corporate and medical campuses in the central county replacing aging walks and parking islands.
Estate, equestrian and farm properties in the western townships that want a stable, natural-looking drive or courtyard.
Marinas and yacht clubs, keeping fueling and boat maintenance areas, which cannot be used for recharge, off the permeable section.

Approval in your town, and what Resin Rock supplies

Start with the municipal planning or zoning board and its engineer, who apply the local stormwater ordinance. If the site fronts a county road or ties into county drainage, the county Development Review Committee also reviews the drainage design. Coastal projects may need NJDEP permits. Boards typically ask for soil logs showing the seasonal high water table, an operations and maintenance plan, and on major developments a deed notice recorded with the county clerk.

For shore and inland projects alike, Resin Rock ships the binder, stone, trims and Rock Crete and provides technical data sheets for the town engineer. Installation is by an approved contractor: we pair owners with one, and New Jersey crews can join our installer training. The municipality and the county make every approval decision.

Before you specify permeable resin-bound in Monmouth County

Find seasonal high groundwater; near the shore it often controls the design.
Check whether the site fronts a county road or drains to county facilities.
Count new impervious surface, and ask whether your town counts reconstructed surface yet.
Keep fueling and boat or vehicle service areas off the permeable section.
Plan an underdrain outlet that works at high tide.
Show a snow storage area away from the permeable surface.

Common questions about permeable resin-bound in Monmouth County

Will Monmouth County review my driveway?

Usually not. The county reviews site plans and subdivisions that affect county roads or drainage, and asks for a drainage analysis when a site has an acre or more of impervious surface, ties into county drainage, or adds 5,000 square feet or more along a county road that drains toward it. A typical driveway is a municipal matter, if it needs review at all. Your engineer or the county Development Review section can tell you which applies.

Our soil is sand. Can we infiltrate everything?

Not always. Monmouth sand takes water quickly, yet the state's 2-foot separation to the seasonal high water table still applies to an infiltrating bed. In towns near the bays, rivers and ocean, that groundwater can sit close to the surface, so an underdrained section may be needed even on sandy lots.

Is a resin-bound overlay on my existing driveway permeable paving?

Not for stormwater purposes. Water gets through the new resin-bound finish, then hits the old slab and runs off the same way it always has. Counting it would take an open-graded stone base plus an infiltration or underdrain route, designed by an engineer and accepted by the reviewing board.
