Re: James H. cohill - Preliminary Major Subdivision Map dated 5/13/87 Dear Mr. Orlowski: The following is in reference to the drainage criteria shown on the above map. The installation of I0 - 10 ft. diam. x 16 ft. leaching pools in a 15 ft. easement at Lot No. 6 will have capacity for a 2" rainfall using the runoff coeffic- ients and tributary areas as used by the designer. The tributary land area used as shown is 459,000 S.F. (~0.54 acres) with runoff from pavement area at 21,600 S.F. Part of the runoff from the subdivision acreage (18.91 Ac.) will not go to Grand Avenue. I recommend approval of the drainage design with the following: Spacing of the leaching pools, except at the catch basin to be 9 ft. apart (side to side). Leave the existing pipe culvert to the easement area in place to act as an over- flow. Also, include on-site disposal of roof runoff for all lots as recommended by the County Soil and Water Conservation District. Respe~lly, . I Raymond L.

Very truly yours, District Manager Enclosure United States Department of Agriculture Conservation Service 127 East Main Street Riverhead, New York 11901 January , 1987 Mr. Stanley A. Pauzer, District Manager Suffolk County Soil & Water Conservation District 127 East Main Street Riverhead, New York 11901 Dear Stan: I have reviewed the preliminary plan for the JAMES COHILL SUBDIVISION at your request. My cormnents are based upon an onsite investigation of the site and review of the plan map submitted. Soil Data and Interpretations: The site, outlined in red on the enclosed soil survey sheet is comprised of three soil types. Haven loam, 0-2 percent slopes (HaA) covers the majority of the property. This soil has few limitations for homesites. A steeper sloping phase of this soil, Haven loam 2-6 percent slopes (HaB), is found in the natural drainageway located along the south property line directly west of lot 7. There is definitely an erosion hazard within this area. It should be planted to permanent grass, especially if it is to be used for agricultural purposes. The grass should extend up to contour elevation 46 as a minimum. Carver Plymouth sands~ 3-15 percent slopes is found in the northwest corner of the property within lot 1, forming the steep bank along Mill Road. The slope of this bank is between 20-25 percent and creates a real problem for access into lot 1. The driveway into lot 1 should be installed on the contour. Cuts perpendicular to the slope should be avoided. Disturbance of this slope should be kept to a minimum. Ail native vegetation currently protecting this slope should be protected as much as possible. Any exposed areas should be limed, fertilized and seeded to a grass mixture tolerant of dry sandy conditions such Creeping Red Fescue 1 LB per 1000 square feet Tall Fescue 1 LB per 1000 square feet Redtbp 0.5 LB per 1000 square feet The seeded areas should be mulched immediately after seeding. Hydroseeding would be the preferred method if available. Storm Water Management: Onsite disposal of roof runoff from the house in lot 1 should be mandatory (see attached Sketch). Any increase in runoff traveling over the steep bank may cause erosion problems and eventual sedimentation of Mattituck Creek. The majority of the runoff travels in a north to south direction, collecting in the southeast corner of the property in l~ts 5 and 6. A culvert pipe was installed at this point under Grand Avenue. It appears that this culvert was installed Mr. Stanley A. Pauzer - 2 - January 6, 1987 to help alleviate ponding and flooding problems along Grand Avenue. The culvert pipe outlets on the southeast side of the road onto private property. With the construction of six houses within this watershed, runoff will in- crease significantly. I would recormmend that the town remove the culvert pipe since its outlet is suspect. The developer should then be required to handle all runoff onsite. The installation of a properly sized recharge basin at this location would be one solution to this problem. If I may be of further assistance with this project let me know. Sincerely, Allan S.

James Coh',~ Subdivision (CPA, CpC, Cp ) These soils are deep, excessively drained and coarse-textured. Soils in these units can be made up entirely of Carver sand~ entirely of Plymouth sand, or of a combination of the two soils. The texture of the Carver soils is fine sand and coarse sand 0 - 22 inches. Coarse sand and gravelly sand is found 22 - 60 inches. The Plymouth soils have textures of fine sand and sand 0 - 27 inches. The permeability of these soils is rapid or very rapid. Available moisture holding capacities are low to very low. Natural fertility and organic matter content of Carver and Plymouth soils is low. The crop response to lime and fertilizer applications is fair. If fertilizer is applied, frequent applications of small amounts should be made to reduce nutrient loss by leaching. These soils are not well suited to crops cormnonly grown in Suffolk County. They are too droughty~ too steep~ too stony or too sandy for crops~ pasture or nursery stock. These sandy soils severely limit installation and maintenance of lawns and land- scape shrubs. A permanent cover of plants should be maintained or restored on all soils in this unit to reduce erosion. CpC Carver and Plymouth sands, 3 to 15 ~ercent slopes. These soils are mainly on rolling moraines; however, they are also found on the side slopes of many drainage channels. Some areas of these soils are as much as 25 percent gravel. In the bottom of many closed depressions, these soils have siltier accumulations' from adjoining hillsides. Silty lenses are sometimes found deep into the lower layers. The erosion hazard is moderate to slight, but a permanent cover of plants should be maintained or restored on this soil. ,TOWN OF SOUTHOLD - J~mes CohO'- Subdivision ~AVEN SOILS (HaA~ HaB~ HaC~ He). Haven soils are deep, well-drained, medium-textured soils that formed in a loamy or silty layer over stratified coarse sand and gravel. The texture from 0 - 19 inches is loam, silt loam, and very fine sandy loam. From 19 - 28 inches the range is silt loam, very fine sandy loam, and gravelly loam, while the texture from 28 - 55 inches is gravelly sand, loamy sand, sandy loam or stratified sand and gravel. The permeability is moderate in the root zone (surface layer and subsoil) and rapid or very rapid in the underlying layer. These soils have moderate to high available moisture capacities (see attached table). Haven soils have low organic~atter content and low natural supply of plant nutrients, but crops respond well to lime and fertilizer.

These soils are usually large in area and nearly level with some areas of slight undulation. The erosion hazard of these soils is slight but erosion problems are likely to occur in undulating areas. Irrigation water should be applied at a moderate rate. Management concerns in- clude crusting after rain, maintaining tilth~ and reduction of the plow pan. HaB Haven loam: 2 - 6 percent slopes. Most small deposits of this soil have short slopes~ but larger areas are undulating. Cultivated areas of this soil are 2 - 3 inches shallower to gravel than the representative Haven soil because of past erosion. 'The erosion hazard of this soil is moderate to slight. The number of consecutive years these soils can be safely cultivated depends on practices used for erosion control and water management. These soils should not be cultivated intensively unless adequate measures are used to help control erosion. In addition to erosion control, management concerns include increasing the organic matter content to help keep the soil loose and crust free~ and breaking up the plow pan. Irri- gation water can be applied at a moderate rate. Practices that help control erosion greatly increase the effectiveness of natural rainfall and irrigation water.

Areas of these soils are usually large and uniform and nearly level with some areas of undulating slopes. The erosion hazard is slight. Moderate droughtiness somewhat limits plant growth unless irrigation water is plied. Returning crop residue to the soil and growing winter cover crops help to protect the surface layer from wind and water damage. The addition of this organic matter also improves the available moisture holding capa- city of the surface layer. C HaB 405 000 FEET RdA HcA (Jolm ~heet 30) ANTHONY B. TOHILL, P. (~.

Could I please schedule a meeting with you to be attended by Howard Young and me as soon as possible. The subdivider does not wish to be unreasonable, but we think this is a matter that reasonable men can discuss. The communication from the Town to the subdivider has been, candidly, awful to the extent that your letter dated March 5 was not sent to me until after the preliminary hearing was closed, during which not a word was mentioned of your letter. It would have made more sense for my client and me not to appear at the preliminary hearing if the only matter open for intelligent discussion was going to be buried and lost in a file.

Our comments of August 31, 1989 have all been adequately address- ed, except for one questionable point. This concerns our original comment with regard to the extensive site work which would have been necessary on lot number one in order to prevent an excessive driveway grade. The revised plan indicates a 25 foot wide right-of-way across lots 2 and 3 to accomplish an acceptable grade. This solution creates a considerable encumbrance on the two lots it crosses, especially lot number two. An acceptable driveway grade could be constructed on lot one through the use of retaining walls and a house with a split-level type configuration. This would eliminate any future disputes among the potential owners of the first three lots involving conflicts over proper use of the right-of-way. We would therefore submit for your consideration that the right- of-way access might very well cause more problems in the future than it is solving. If you wish to discuss this situation further, please give us a call. Very truly yours, SIDNEY B. BOWNE & SON CONSULTING ENGINEERS A. BAKIUN CASS, P.E. ABC:cl9 xc: R. Jacobs, Supt./Hwys. R.

Additional leaching basins should be provided along the Mill Road frontage to intercept the runoff. It should be noted that the leaching basins shown adjacent to the Grand Avenue frontage should be installed with a minimum clearance of 10 feet between basins. It should also be noted that steep grades exist on proposed lot number 1. Extensive site work will be necessary to provide an acceptable driveway grade on this lot. If we may be of further assistance please give us a call. Very truly yours, SIDNEY B. BOWNE & SON CONSULTING ENGINEERS A. BARTON CASS, P.E. CSH:clg Encl. (map) xc: R. Jacobs, Supt./Hwys. R.
