I. INTRODUCTION

Mountain Road Preserve, LLC is proposing a 49 lot residential subdivision, known as SevenPeaks at Mountain Road, in the Town of Mamakating, Sullivan County, New York. The projectsite consists of 653.71 acres located on the north side of Hamilton Road *(CR65) andMountain Road. The 49 lot subdivision will be developed on 561.77 acres of the site. Each lotwill be developed with a single family residential dwelling. Wastewater generated by thedwellings will be disposed of utilizing on lot subsurface disposal systems. This report wasprepared to evaluate the suitability of the soils on the project site for individual sanitarywastewater disposal systems.

II. DEEP SOILS TEST PITS

A series of deep soils test pits were excavated on the project site. The purpose of these testswas to determine the following information:

1. The presence or absence of underlying substructure that effect the vertical movement ofwastewater.

2. High groundwater levels3. Depth to bedrock4. Types of soils encountered

The results of the tests are provided as an attachment to this report. The results indicate thatusable soil depths varying from approximately 24" to 84" can be found across the site.

III. WASTEWATER DISPOSAL

The single family residential dwellings will utilize individual on lot sewage disposal systems.Requirements for these systems are included in the New York Department of Health'sAdministrative Rules and Regulations Design Standard (10 NYC RR Appendix 75A), which iscommonly referred to as "Appendix 75A". Guidance in uniformly implementing theserequirements is given in handbook published by the Department of Health in 1996 and entitled"Individual Residential Wastewater Treatment Systems Design Handbook".

Conventional sewage disposal systems identified in the Department of Health publicationsinclude the following:

1. Absorption field systems2. Gravellness absorption systems3. Deep absorption systems4. Shallow absorption systems5. Cut and fill systems6. Absorption bed systems7. Seepage pits

F:\2007\07-715 - Seven Peaks (Black Creek Development)\Correspondence\Reports\Soils Report 8.14.9.doc

These conventional sewage disposal systems require a minimum of four (4) feet of usable soilabove bedrock, impermeable strata or groundwater. The results indicate that usable soil depthvaries from approximately 24 inches to 84 inches above bedrock.

Of the conventional sewage disposal systems identified above, it appears that the onsite soilsare conducive to the use of absorption field, gravelless absorption and shallow absorptionsystems. On lots where the depth to bedrock exceeds 48 inches, absorption field systemsmay be constructed in accordance with NYSDOH requirements. On lots where the depth tobedrock ranges from 24 inches to 48 inches, shallow absorption field systems shall be installedin accordance with the NYSDOH requirements.

IV. CONCLUSION

Extensive soils testing was performed throughout the Seven Peaks at Mountain project site.Based upon the results of this testing, it appears that suitable soils exist to support individualon-lot sanitary disposal systems for the 49 single family homes.

Respectfully submitted,

Matthew J. Sickler, P.E.Associate
