Paver Patios, Walkways and Stone Steps in the City of Syracuse

In the City of Syracuse, 1.5 percent of the mapped soil area is classed poorly drained, somewhat poorly drained or very poorly drained, and 54.0 percent is classed well drained. About 22.0 percent of the city is mapped as urban land with no natural drainage class, and the largest natural soils are Palmyra gravelly loam on 0 to 3 percent slopes at about 9.4 percent and on 3 to 8 percent slopes at about 6.7 percent. Palmyra is well drained hydrologic group A, the fastest-infiltrating group there is, and Honeoye silt loam adds a further 11.9 percent.

The City of Syracuse issues residential construction permits for one and two family homes and names the work that needs one, including retaining wall, driveway, fence, deck, porch, gazebo and pergola, shed and garage, and a miscellaneous category covering chimney and foundation or site work. Its published list of work needing no permit includes sealing or adding an additional layer of tarvia to a driveway, but does not include building a new driveway. Neither list names a patio at grade.

Onondaga County's Green Improvement Fund does fund porous pavement, but not for homeowners. The program describes itself as supporting green infrastructure on commercial, business and not-for-profit owned properties in the Clinton, Harbor Brook and Midland combined sewersheds, which are select areas within the City of Syracuse. Eligible measures include rain gardens, bioretention, dry wells, underground infiltration systems, green roofs, porous pavement, tree plantings, planter boxes and cistern systems. The program reports over 11.6 million dollars awarded across 98 completed projects, and its page states that it is not currently accepting applications.

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.
