Paver Patios, Walkways and Stone Steps in DeWitt

In the Town of DeWitt, 28.9 percent of the mapped soil area is classed poorly drained, somewhat poorly drained or very poorly drained, and 26.8 percent is classed well drained. Niagara silt loam is the largest single map unit at about 11.8 percent, and a further quarter of the town carries no natural drainage class at all because it is mapped as urban land at about 8.9 percent, quarries at about 6.5 percent and cut and fill land at about 6.1 percent.

There is no state-wide or county-wide frost depth figure in the New York code. Section R301.2 states that additional criteria shall be established by the local jurisdiction and set forth in Table R301.2(1), and the table's own footnote for the frost line depth column reads: the jurisdiction shall fill in the frost line depth column with the minimum depth of footing below finish grade. The column is published blank.

New York's own code agency confirms it. Technical Bulletin TB-1009-RCNYS from the Department of State Division of Building Standards and Codes states, under Subject to damage from Frost Line Depth, that the local jurisdiction shall provide the minimum depth of footing below finish grade, and that the considerations a local jurisdiction can use when developing its frost line depth include, but are not limited to, air freezing index, soil type, water table depth, local historical data and field experience. The bulletin also notes that where an authority having jurisdiction spans multiple municipalities the data should be filled out for each municipality individually.

The Census Building Permits Survey counts new single-family housing units authorized by each permit-issuing place, which is the closest published proxy for where new masonry is actually being built. Across 2022, 2023 and 2024 combined, Onondaga County municipalities authorized new single-family units as follows: Town of Lysander 178, Town of Clay 89, Town of Camillus 86, Town of Onondaga 83, City of Syracuse 56, Town of Cicero 37, Town of Manlius 34, Town of Skaneateles 23, Town of DeWitt 17, Town of Van Buren 15, Town of Marcellus 14, Marcellus village 13, Town of Geddes 11, Skaneateles village 9, Manlius village 8, Town of Salina 8, Solvay village 4, Baldwinsville village 2, Fayetteville village 2, Liverpool village 1, and Camillus village, East Syracuse village and North Syracuse village 0 each. In 2024 alone the county authorized 323 new single-family units with a combined reported construction value of about 101.3 million dollars.

Ranked by the share of housing units built in 2000 or later, the era in which adhered stone veneer and segmental paver hardscape became the dominant new masonry products, the places of this metro spread very widely. Radisson, the census place inside the Town of Clay, leads at 32.4 percent, followed by the Town of Lysander at 25.8 percent, the Town of Van Buren at 21.9 percent, Baldwinsville village at 20.1 percent, the Town of Cicero at 19.1 percent, the Town of Clay at 15.4 percent, the Town of Camillus at 15.2 percent, the Town of Manlius at 11.6 percent, the Town of Marcellus at 11.3 percent, the Town of Skaneateles at 11.2 percent, Marcellus village at 9.9 percent, the Town of DeWitt at 8.7 percent, Skaneateles village at 8.4 percent, Fayetteville village at 8.1 percent, the Town of Salina at 7.0 percent, the City of Syracuse at 6.4 percent, Camillus village at 6.4 percent, Liverpool village at 6.1 percent, North Syracuse village at 4.7 percent, Manlius village at 4.5 percent, and both East Syracuse village and Solvay village at 0.0 percent. The county figure is 11.6 percent.

The hardscape industry's own base specification is short and checkable. It states that the thickness of the base is determined by traffic, soil type, subgrade soil drainage and moisture, and climate; that sidewalks, patios and pedestrian areas should have a minimum base thickness after compaction of 4 inches over well-drained soils; that residential driveways on well-drained soils should be at least 6 inches thick; and that in colder climates, continually wet or weak soils will require that bases be thicker.

Compaction is a measurable number, not a matter of judgment. The specification states that compaction of the soil subgrade is critical to the performance of interlocking concrete pavements, that adequate compaction will minimize settlement, and that compaction should be at least 98 percent of standard Proctor density as specified in ASTM D698. It adds that this compaction standard may not be achievable in extremely saturated or very fine soils and that stabilization of the soil subgrade may be necessary in those situations.

Two further numbers from the same document. Base material is to be spread and compacted in 4 to 6 inch lifts using a 7,000 pound-force reversible plate compactor, with thinner lifts required for compactors in the 5,000 pound-force range. And the finished surface must drain: slopes should be a minimum of 1.5 percent.

Unit paving is a flexible pavement and it is designed to move. The specification notes that the top of installed pavers may be set 1/8 to 1/4 inch above the final elevations to compensate for possible minor settling, and states directly that a small amount of settling is typical of all flexible pavements.

The hardscape specification carries its own cold weather rule, and it is absolute: frozen base material should not be installed, nor should material be placed over a frozen soil subgrade.
