Re.: Subsurface Investigation Woodland Hills – Hoag Lane Subdivision Town of Manlius, NY

Dear Tom,

Pursuant to your request and authorization, Kenney Geotechnical Engineering Services, PLLC has performed additional subsurface investigation at the Woodland Hills project site. The purpose of the additional subsurface investigation was to provide data for road design and to provide a preliminary screening for karst features. The scope of the additional investigation included eight soil borings (designated as B-1 through B-8), a site reconnaissance, and a review of publically available mapping and geologic information.

No environmental services are included in this study. No conclusions have been drawn regarding environmental conditions of the site, potential contaminants, potential special treatment or disposal of site materials, or other environmental considerations.

Subsurface investigations were performed at the locations designated on mapping prepared by Keplinger Freeman Associates Landscape Architecture. The site was heavily vegetated at the time of this investigation. The investigation was performed using a track-mounted Geoprobe 7822DT drill rig. Hollow stem augering techniques were utilized to advance the test borings to a maximum depth of 10 feet or auger refusal. Standard penetration testing (ASTM D1586) was performed with an automatic hammer to obtain soil samples. Boreholes were back-filled with cuttings and sealed with a two foot lift of bentonite hole plug.

Subsurface Conditions Encountered- Road Borings Based on our review of the recovered samples, standard penetration testing, and drilling observations, the subsurface conditions encountered by the test borings generally consisted of:

0.5 to 2.0 feet of topsoil, overlying

Main 6/13/2019 Kenney Geotechnical Services

Soft to medium stiff silty clay with gravel to depths of approximately two to ten feet, overlying

Hard glacial till. Underlying the soft to medium silty clay in several borings (B-4 and B-6) was a layer of sandy silt with some gravel and possible weathered rock. “N” values in the sandy silt layer ranged from 9 bpf to greater than 100 bpf. Glacial till was encountered in half of the borings (B-1, B-2, B-5, B-8) and consisted of sandy silty clay with gravel. “N” values in the till were typically greater than 30 bpf. In general, it appears that after stripping topsoil the road subgrade will consist of silty clay ranging from stiff to hard in stiffness. The silty clay will be susceptible to strength loss due to saturation and excessive vibration if not properly managed during construction. The subgrade should be sealed with a pass of a smoothdrum roller at the end of each working day, and before rain events, to prevent unnecessary saturation during construction. The silty clay will generally have a low permeability, so proper drainage of the subgrade will be an important influence on roadway longevity. The subgrade should be sloped to drain, and perimeter under drains may be necessary. Given the conditions encountered, we would suggest a California Bearing Ratio of 5 is utilized for roadway design. However, the road subgrade should be thoroughly reviewed during construction for the presence of soft areas that may required undercutting and replacement with structural fill. Karstic Conditions Reconnaissance The Hoag Lane Subdivision lies within the Appalachian Plateau physiographic province. Major topographic and geologic features in this area were formed during the last glacial advance and retreat, which ended approximately 12,000 years ago. Regional surficial geologic mapping suggests that natural soils in the site vicinity generally consist of glacial till and kame moraine deposits. Bedrock mapping suggests that Manlius formation limestone underlies soil in the area. The term ‘karst’ has traditionally been used to refer solely to regions of exposed soluble bedrock having an abundance of surface landforms, such as sinkholes, sinking streams, and springs, that reflect the presence of subsurface voids or caves. The Town of Manlius has apparently identified areas in the vicinity of the project site as Critical Environmental Areas with “Sinkholes, sinking streams, and seasonal streams, which are indicative of karst topography” (Town of Manlius, 2009).


We asked to see the mapping associated with this declaration, but the Town would not provide us with the mapping without a formal Freedom of Information Law (FOIL) request. We have submitted the FOIL request but have not received a response as of the date of this report. Karstic conditions are often revealed through a review of topography. Steep elevations changes, circular depressions, and sinkholes would be typical indicators. We performed a walking site reconnaissance of the site, and also utilized USGS topographic mapping and publically available aerial imagery to search for possible topographic indicators of karstic conditions. In general, the site slopes gently downward to the west, with elevations ranging between 670 and 770 feet above sea level (USGS National Map, Accessed 2019). No distinct karst topographic features (i.e. sinkholes, circular depressions, steep elevation changes, etc.) are apparent in the immediate project vicinity. Thank you for the opportunity to be of service, and please contact me at your convenience with any questions you may have.

Division of GM and SM groups into subdivisions of d and u are for roads and airfields only. Subdivision is based on Atterberg Limits:suffix d used when L.L. is 23 or less and the P.I. is 6 or less; the suffix is used when L.L. is greater than 26.Borderline classifications used for soils possessing characteristics of two groups are designated by combinations of groups symbols.For example; GW-GC, well-graded gravel-sand mixture with clay binder.
