Paver Patios, Walkways and Stone Steps in Clay

In the Town of Clay, 44.4 percent of the mapped soil area is classed poorly drained, somewhat poorly drained or very poorly drained, and 9.6 percent is classed well drained. The largest map units are Collamer silt loam on 2 to 6 percent slopes at about 19.7 percent of the town, Niagara silt loam on 0 to 4 percent slopes at about 17.1 percent, and Rhinebeck silt loam at about 8.6 percent, with Carlisle muck at about 4.1 percent.

Niagara silt loam, the second most extensive soil in Onondaga County and the dominant soil across the northern towns, carries a seasonal high water table with its top at about 31 centimeters, roughly 12 inches, below the surface, and the county soil data records that condition for December, January, February, March, April and May. Rhinebeck silt loam has the same 31 centimeter figure. Kendaia silt loam is shallower at about 20 centimeters, roughly 8 inches. For comparison, Collamer silt loam is about 54 centimeters, roughly 21 inches, and Honeoye silt loam about 76 centimeters, roughly 30 inches.

Both of the fast-growing northern towns name fireplaces on their list of work requiring a building permit and neither names a patio. The Town of Clay lists new buildings, all additions and alterations, mobile homes, garages and barns, pools, sheds and storage buildings, decks and porches, fences, signs, fireplaces, stoves and inserts, and demolition. The Town of Cicero lists decks, porches and garages, fireplaces, pellet stoves and wood stoves, storage sheds no matter the size, fences, swimming pools, and structural, plumbing or electrical alterations, and requires a permit before excavation or filling of more than 10 cubic yards. Cicero also requires a Floodplain Development Permit for any work in a 100 year flood zone, including work that would not otherwise need a permit.

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 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.

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.
