Parking Lot Sealcoating and Line Striping for Anderson Property Managers

September 9, 2026

Anderson's zoning guide sets the floor for a commercial lot, the 2010 ADA Standards set the stripes, and the freeze-thaw calendar sets the schedule.

What Anderson's zoning guide expects of a lot

The City of Anderson's Zoning Guide, dated July 25, 2024, is short on sealcoating and clear on the basics. All areas devoted to off-street parking, including drives and access points and excepting single-family dwellings, must be paved: plant mix asphalt, penetrating asphalt or concrete. Asphalt millings are allowed only at the discretion of the Board or the Building Commissioner. A parking space is defined as not less than 10 feet wide and 18 feet long, exclusive of passageways, and the lot must drain to the standards of the city's Storm Drainage and Sediment Control Ordinance, with a drainage permit.

For a property manager that sets the floor: a gravel or millings lot on a commercial parcel is a zoning question, not a maintenance choice; a restripe should not shrink stalls below 10 by 18; and regrading that changes where water leaves the lot touches the drainage permit. Sealcoating and striping are the moment to check all three.

ADA striping: the numbers that get lots cited

Line striping is where compliance is won or lost, because the 2010 ADA Standards for Accessible Design measure stalls and aisles in inches and every restripe redraws them.

• Count: 1 accessible space for a lot of 1 to 25 total spaces, 2 for 26 to 50, 3 for 51 to 75, 4 for 76 to 100, 5 for 101 to 150 and 6 for 151 to 200 (Table 208.2).
• Van spaces: for every six accessible spaces or fraction of six, at least one must be van-accessible (208.2.4), so a lot with a single accessible space needs it to be the van space.
• Width: car accessible spaces 96 inches minimum; van spaces 132 inches minimum with a 60-inch aisle, or 96 inches with a 96-inch aisle (502.2).
• Access aisle: 60 inches wide minimum, the full length of the space, marked so as to discourage parking in it, and never overlapping the vehicular way (502.3).
• Slope and signs: surfaces not steeper than 1:48 (502.4), sign bottoms 60 inches minimum above the surface (502.6), and spaces on the shortest accessible route to the entrance (208.3).

Phasing a lot so the business stays open

A sealcoat needs about 24 dry hours before tires return, and striping goes on after the sealer has set. The way to keep a store, clinic or church open is to split the lot into sections that each keep an entrance, a drive lane and the accessible spaces available while the other section cures.

A typical sequence: crack fill and patch the whole lot first, since that work does not close it; then seal half or a third at a time on consecutive dry days; then stripe each section as it opens. Overnight or weekend work suits retail on the Scatterfield Road corridor, where the lot empties after close; a church can seal Monday through Thursday. Cones, tape and a sign at each curb cut do the rest, and tenants should get the closure map in writing a week ahead.

The Anderson calendar for commercial work

The sealing season in Anderson runs from late April to early October, and May and September are the busiest months, so a lot that wants a September date should be scoped in July. September has the fewest rain days of the year at Indianapolis, 7.9, and Anderson's normal first 32-degree freeze is October 18, which makes late-September work a race against the first frost. Crack filling runs longer: INDOT's specification only halts it when the pavement is wet or the air is below 40 degrees F, so cracks can still be sealed in November.

Inspect in April, when thawed ground shows standing water and soft spots that September hides, and put the findings into the year's scope. The Crosby clay under most of Madison County holds a perched water table 0.5 to 2.0 feet down through winter and spring, so a lot that ponds in April is telling you where the base will fail next.

A maintenance plan instead of a replacement budget

The case for an asphalt maintenance plan is arithmetic the pavement does on its own. The Indianapolis station averages 98.6 days a year at or below 32 degrees F, the region sees about 42 freeze-thaw cycles, and INDOT brine rides in on every car that turns off State Road 9 or State Road 32. Water in the base plus those crossings is what turns a crack into alligatoring and alligatoring into a base repair.

The plan that matches that climate: crack filling every year, parking lot sealcoating every two to three years, patching before winter, and line striping last, after the sealer, so the lines sit on the new surface. Written as a multi-year schedule with a spring inspection built in, it turns an unpredictable capital hit into a line item, which is how commercial sealcoating in Anderson and the surrounding towns should be scoped: as a program, not a one-time coat.

What the written scope should contain

Compare scope before comparing price. A complete commercial scope lists the square footage sealed and the linear feet of cracks filled as separate lines; the product family and name, coat count, coverage rate per coat and sand load; patch locations, sizes and depth, noting which are base failures; the phasing map, closure hours per section and who places the barricades; the striping layout with stall count, stall size, accessible spaces, aisles, arrows and fire lanes; and the year each section is next due for sealing.

Send that list with a site plan through the contact page and the quotes that come back can be compared line by line instead of by total.
