O30 Princeton Hydro Report Dated 9 3 25

3/31/25, 1:08 PM Official Series Description - BOONTON Series loam, loam, fine sandy loam or sandy loam in the fine earth fraction. Some pedons have thin unplowed A horizons up to 5 centimeters thick with color and texture the same as the Ap. The BA or BE horizon commonly has hue of 7.5YR or 10YR but the range includes 5YR, value of 4 or 5, and chroma of 3 to 6. Texture is silt loam, loam, fine sandy loam, or sandy loam in the fine earth fraction. The Bt horizon has hue of 2.5YR to 10YR, value of 3 to 5, and chroma of 4 to 6. Pedons with the redder hues have a higher proportion of red sandstone or shale. Texture is fine sandy loam, sandy loam, loam, or silt loam in the fine earth fraction. Structure is commonly moderate to weak, coarse to fine subangular blocky. Some pedons have platy structure in places. The Btx or Bx horizon has hue of 2.5YR to 10YR, value of 3 to 5, and chroma of 3 to 6. Texture is sandy loam, fine sandy loam or loam in the fine earth fraction. Structure is weak or moderate very coarse prismatic to moderate or strong, thin to very thick platy. It is very firm or firm, and brittle. Some pedons may have a BC horizon. The Cd or C horizon has hue of 2.5YR to 10YR, value of 3 to 6, and chroma of 3 to 6. It is commonly loam, sandy loam, fine sandy loam, or loamy fine sand in the fine earth fraction but the range includes loamy sand in some places. It has weak medium to thick platy layers or is massive, and consistence ranges from very firm to very friable. In some pedons the C layer is loose friable till. COMPETING SERIES: There are no other series currently in the same family. The Readington, Rockaway, Turbotville, and Wooster series are in related families. Rockaway soils have rock fragments dominated by granitic gneiss and have less than 35 percent base saturation in the lower part of the solum and C horizon. Readington, Turbotville, and Wooster soils are fine-loamy. GEOGRAPHIC SETTING: Boonton soils are on gently sloping to very steep uplands. Slope is usually smooth and regular and gradient ranges from 0 to 50 percent. The soils formed in glacial till composed mostly of red to brown shale, sandstone, basalt, and some granitic gneiss. The climate is humid temperate. Mean annual temperature ranges from 10 to 14 degrees C and precipitation ranges from 1020 to 1140 millimeters. Frost free season is 130 to 150 days. GEOGRAPHICALLY

ss. The climate is humid temperate. Mean annual temperature ranges from 10 to 14 degrees C and precipitation ranges from 1020 to 1140 millimeters. Frost free season is 130 to 150 days. GEOGRAPHICALLY ASSOCIATED SOILS: Holyoke and Haledon are the most extensive associated soils and are developed from similar materials. Holyoke soils are shallow to basalt bedrock and usually are on higher and steeper positions in the landscape. Haledon soils have low chroma depletions in the top 10 inches of the argillic horizon and are in lower positions in the landscape, in drainageways, or at the base of steeper slopes. Other associated soils are Riverhead and Dunellen which formed in stratified, water sorted material. DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well and well drained. Runoff is slow to rapid. Saturated hydraulic conductivity is moderately low to high in the mineral soil above the fragipan, low or very low in the fragipan, and low to high below the fragipan. There is a perched water table at a depth of 46 to 91 centimeters from November to May of most years. USE AND VEGETATION: Most Boonton soils are in areas that have become highly urbanized. Undeveloped sites are wooded or idle fields. Wooded areas have oaks, red maple, white ash, hickory, gray birch, and dogwood trees. DISTRIBUTION AND EXTENT: Till uplands in Northeastern New Jersey and southeastern New York. MLRA 144A and 149B. The series is of moderate extent (62,000 acres). MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts SERIES ESTABLISHED: Morris County, New Jersey 1971. REMARKS: A\fisols classification is inferred from decreasing acidity and the high proportion of ultra basic grains and fragments in the lower part of the solum and C horizon. CE activity class is inferred from similar soils. Geographic coordinates were determined from the narrative description for the type location. Diagnostic horizons and feature recognized in this pedon include: 1. Ochric epipedon - the zone from the surface of the soil to a depth of 38 centimeters (Ap and BA horizons). 2. Argillic horizon - the zone from 38 to 127 centimeters (Bt1, Bt2, and Btx horizon). 3. Fragipan - the zone from 76 to 127 centimeters (Btx horizon). https://soilseries.sc.egov.usda.gow/OSD_Docs/B/BOONTON. htm! 213
