He welcomed everyone to the May 14, 2015 Planning Board meeting, He asked that all cell phones be turned off, and that anyone addressing the Board do so from the podium, using the microphone. Chairman Zuckerman introduced the Board members and the Village Staff and explained the rules of procedure for the meeting. He introduced the Planning Board's newest member, Mr. Sal Morlino, and thanked Mr. Bill Laufer for his years of service. Chairman Zuckerman made note for the public that the complete set of Planning Board Rules of Procedure can be found on the Village's website, and the meeting could be viewed on streaming video and on the Village's public access channel. Chairman Zuckerman called for the first item on the agenda. Planning Board Meeting May 14,2015 Page 2 MINUTES Review of minutes from March 12, 2015 Mrs. Schoen noted an error in the summary on page 3. The summary was adopted as amended. Mr. Nowak, Superintendent of Public Works, called the roll: Domenic Accurso Voting Aye Robert Goodman Voting Aye John Grzan Voting Aye Sal Morlino Voting Aye Amy Schoen Voting Aye Daniel Tartaglia Voting Aye Chairman Gary Zuckerman Voting Aye AFFORDABLE HOUSING: 1) Review of a Site Plan Application by Buckingham Partners / Sun Homes for a Planned Unit Development with a Fair and Affordable Housing component located at 1100 King Street, Rye Brook, NY, Parcel ID 129.25-1-1. Gerry Schwalbe, representative for the applicant, addressed the Board. He gave an overview of the proposal. Since the last meeting, a site visit took place at a development in Darien, Connecticut constructed by the applicant, which is similar to the proposal currently before the Planning Board. The plans have now been updated in reference to comments received and new plans have been submitted. The design of the affordable units has been revised and the affordable units now appear similar to the market-rate units. By shifting the location of the homes slightly, the buffer between the affordable units and the Reckson Executive Park parking lot has been increased to at least 50 feet, and in some locations, more than 50 feet. He showed the Board how the buffer was altered to increase the distance from the property line. Bill McGuinness of Sun Homes addressed the Board. He reviewed the changes to architecture of the affordable units. He noted that the garages are now underneath the affordable units rather than across the street. Several parking stalls are located on the opposite side of the street instead of detached garages. He presented elevations of the proposed affordable units and market rate units to show their similarities. Dan Tartaglia asked about the square footage of the units, which will be between 1,100 and 1,500 Planning Board Meeting May 14,2015 Page 3 square feet in size. Chairman Zuckerman noted that these may be the largest affordable units in Westchester County. Additional landscaping has been added in the buffer that will be to the same specifications as the market-rate homes. Mr. McGuiness added that the driveways were lengthened to accommodate a parked car as well. In response to a question raised by Mrs. Amy Schoen, Mr. McGuinness noted that 10 to 12-foot high trees will be staggered in a row to provide screening between these units and the Reckson Office Park parking lot. Mr. Schwalbe presented three cross-sections through the property to the Board to show the elevation changes on the site. Some filling will occur, but, in general the current grade of the site will be maintained. John Grzan asked about setbacks. Mr. McGuiness confirmed the setbacks are similar throughout the property. Marilyn Timpone-Mohamed, the Village Planning Consultant, reviewed the comments set forth in her most recent memos. She commended the applicant on the appearance of affordable units. She felt the redesigned buildings will be similar in appearance to the market rate homes. She addressed the increased buffer and the longer driveways. She continued to recommend that the affordable units be dispersed throughout the development rather than clustered. She noted that the applicant's traffic study was received and was under review. John Grzan favored the reconfiguration of the affordable homes, and understood that the roadway in front of them needed to be straightened out to allow for the longer driveways. The Board and the applicant discussed planning considerations associated with signage for the project on King Street. The Reckson Office Park owns the frontage on King Street, not the applicant, so Reckson will likely need to go through site plan approval for any new signage. Dan Tartaglia asked if the applicant has given more thought to how affordable unit owners will be able to partake in the site amenities. Mr. McGuiness responded that they are leaning toward an a la carte option. The Board asked about the recreation area adjacent to the affordable units. Anthony Gioffre, Esq. responded that this project is at the conceptual phase, so while the recreation area has been identified, the exact purpose has yet to be determined. Planning Board Meeting May 14,2015 Page 4 Chairman Zuckerman asked about the school children study. Mr. Gioffre responded and reviewed the findings of the report provided by Divney Tung Schwalbe on the school aged children that would be generated by the project. The Chairman asked Mrs. Timpone-Mohamed if she had any comment. She responded that using the Rutgers multipliers is the typical method of calculating school aged children. Use of the actual Blind Brook School District statistics provides a more conservative calculation, but the difference between the two outcomes is minimal. Chairman Zuckerman noted that the number of school children likely to be generated from the project does not seem to be an overwhelming number. John Grzan asked about Bellefair and whether the number of students actually added to the district was similar to the number estimated for that project. The Chairman recalled that the actual number of students from Bellefair exceeded what had been estimated. He noted that the studies are projections and may not be 100% correct. The Board cannot do any more than ensure that acceptable methods have been implemented to make the projections. Mr. McGuiness reminded the Board that they will be back before the Board with more detailed plans that will show a lot more detail on the landscaping and the proposed trail network. Mr. Accurso questioned the number of units, and noted that he was concerned about the density. He noted that, as a P.U.D., the zoning density should mirror the Arbors. He commended the applicant on the modifications of the affordable units. He asked the applicant to consider the location of the club house. A question was also raised regarding the amount of parking around the club house. It was noted that there is a lot of parking within the development. Chairman Zuckerman noted that the Rye Brook Emergency Services Task Force was reviewing the plans. He looked forward to reviewing the next set of plans. He reiterated that the applicant has done a great job in amending the plans in response to the concerns raised. He also thanked the applicant for arranging the site visit to the development in Darien, Connecticut. The homes were beautiful and the construction was excellent. Review of the plans will continue, and the matter was adjourned to the June 11, 2015 meeting of the Planning Board. PUBLIC HEARING: 2. Review of an Application by JFM Architect, on behalf of Julia Haney, for approval of a Site Plan to legalize a two-family conversion at the existing Planning Board Meeting May 14,2015 Page 5 front residence located at 525 Ellendale Avenue, Rye Brook, NY, Parcel I.D. 141.27-1-50. On a motion and a second the public hearing was opened and the roll was called. The matter was before the Planning Board because it is a change of use affecting parking. The lot contains two independent single-family dwellings, and one was converted to a two-family home years ago. Joe Mansfield, architect, addressed the Board. The home has been owned by the family for five generations. The applicants want to legalize the two-family dwelling. The property is in the R2-F Zone, which allows two-family dwellings. The Village's maintenance yard is directly across the street from the property. The applicant's grandmother purchased the home in 1908. It was a two-family home at that time. Over the years the home has remained a two-family home. Chairman Zuckerman called for members of the public wishing to address the Board in support or opposition to the application. There being no one, the public hearing was closed. Mr. Tai-taglia noted that he grew up on the same block as this property and the house has always been a two-family home as long as he could remember. Philip Butler, Esq., Village Counsel, read the following resolution: May 14, 2015 APPROVED 7-0_ RESOLUTION GRANTING SITE PLAN APPROVAL TO LEGALIZE AN EXISTING TWO-FAMILY CONVERSION OF THE MAIN RESIDENCE LOCATED AT 525 ELLENDALE AVENUE WHEREAS, an application has been submitted by Julia Haney (the "Applicant") for site plan approval to legalize the conversion of the main residence located at 525 Ellendale Avenue, located in the R2-F District, from a one-family to a two-family residence; said property being identified as Section 141.27, Block 1, Lot 50 on the Town of Rye Tax Assessor's Map; and WHEREAS, the Planning Board reviewed the following plans and application materials in connection with the proposed application: Planning Board Meeting May 14,2015 Page 6 1. Short Environmental Assessment Form 2. Exterior Building Permit Application 3. Site Plan Application and Checklist Sheet Number Sheet Title Dated G-1 Code Notes, Zoning Tabulation & Plot Plan 12/1/2014 A-1 Existing Crawl Space Plan & Existing First Floor Plan 12/1/2014 A-2 Existing Second Floor Plan & Existing Unoccupied Attic Plan 12/1/2014 SP-1 Zoning Tabulation & Site Plan 12/1/2014 and WHEREAS, on April 9, 2015, the Planning Board adopted a resolution setting the Public Hearing on this application and declaring same to be a Type II Action pursuant to SEQRA; and WHEREAS, on May 14, 2015, the Planning Board opened a public hearing on the subject application, at which time all persons interested were given an opportunity to speak on behalf of or in opposition to said application, and WHEREAS, the Planning Board then closed the public hearing on May 14, 2015; and WHEREAS, the Village Planning Consultant, Village staff and the Planning Board have reviewed the information and submitted comments regarding the application; and WHEREAS, the Planning Board is fully familiar with the site and all aspects of this application. NOW, THEREFORE, BE IT RESOLVED, that the Village of Rye Brook Planning Board hereby approves the application referenced herein; and BE IT FURTHER RESOLVED, that no permits shall be issued until the applicant has paid to the Village all applicable fees and professional review fees incurred in connection with review of this application. On motion by Ms. Schoen, seconded by Mr. Grzan, Mr. Michel Nowak, Superintendent of Public Works, called the roll: Planning Board Meeting May 14,2015 Page 7 Domenic Accurso, Jr. Voting_Aye_ Robert Goodman Voting_Aye_ John Grzan Voting_Aye_ Sal Morlino Voting_Aye_ Amy Schoen Voting_Aye_ Daniel Tartaglia Voting_Aye_ Gary J. Zuckerman, Chairman Voting_Aye_ CONTINUED BUSINESS: 3) Review of an Application by Frank Madonna for approval of a Site Plan, Subdivision (Lot Merger) and Petition for Re-zoning, to construct a mixed use Multi-Family/Retail Building on property located at 80 Bowman Ave, Rye Brook, NY, Parcel I.D. 141.27-1-26,31,32. Mr. Zuckerman reviewed the procedural history of the project and its status. He noted that at the last meeting three actions were taken. A memorandum was received from the Building Inspector citing certain non-conformities from the State Fire Code that will require variances. The applicant has advised that it is now submitting new plans that, they believe bring the project into compliance with the State Fire Code, and answer the Building Inspector's comments. Anthony Federico, architect, addressed the Board. He informed the Board that the Village Board will hold a public hearing on May 26th regarding the zoning change. A determination of significance must be made by the Planning Board to move the application forward. The applicant will be before the Zoning Board of Appeals on June 2nd, but the applicant is awaiting the Building Inspector's decision with respect to the modified plans and whether they comply with the state fire code and answer his comments. Chairman Zuckerman noted that the meeting of the Emergency Services Task Force will not take place until after June 2nd Mrs. Marilyn Timpone-Mohamed addressed the Board. She reviewed the plans, noting that the exit driveway is located too close to Bowman Avenue. This is a safety issue for drivers and pedestrians. There must be a greater distance between Bowman Avenue and the driveway curb cut, which must be resolved. Planning Board Meeting May 14,2015 Page 8 Mr. Federico noted that the applicant has submitted revised plans that were rejected. He asked for guidance from the Planning Board to help resolve this issue. The fire truck has a turning radius of 50 feet. It would require a circle of 100 feet wide. Bowman Avenue is only 36 feet in width. There is no way to accommodate the turning radius without eliminating all of the parking in front. Mr. Zuckerman noted that there are two problems: the traffic safety problem and the fire code problem. Both problems need to be resolved. The Chair asked that the applicant work with the Village's Consultant and the Building Inspector to resolve these issues. He noted you cannot solve one problem by creating another problem. Mr. Federico noted that he might be able to solve the fire code issue by eliminating a few spaces in front of the building. Mrs. Timpone-Mohamed indicated that there may still be more parking provided than what is actually needed for the property. The County Planning Commission submitted comments regarding the application. The Chairman suggested that the applicant review the County recommendations and take them into account, particularly with regard to the County Master Plan and moving the building closer to the street. Mr. Tartaglia noted that moving the location of the building will not resolve the fire code issue. Chairman Zuckerman expressed his opinion that it would be a better project with the building closer to the street and he wasn't sure that the absence of parking would really affect the marketability of the retail space. Mrs. Timpone- Mohamed also questioned the height of the building. With the consensus of the Board, the application was adjourned to June 11, 2015. 4) Review of an Application by 8 Edgewood, LLC, (Frank Chiarello) for approval of a Site Plan and Wetlands Permit to tear down and construct a single-family dwelling on the property located at 8 Edgewood Drive, Rye Brook, NY, Parcel I.D. 135.28-1-28. Chairman Zuckerman noted that he was within the notification area and that he would be recusing himself from review and voting on this application. Robert Goodman would address the matter as the Acting Chairman. The applicant's representative, Mr. Vieira, noted that the Zoning Board of Appeals granted the setback variance. The plans were modified in response to the Zoning Board's comments. Mrs. Timpone-Mohamed noted that the applicant submitted EPA and NYSDEC data searches, cleanup reports and other documents regarding hazardous materials. There was no indication in the materials submitted that the mercury spill on the 55 Hillandale Road property had migrated onto the subject property. The applicant will indicate the limits Planning Board Meeting May 14,2015 Page 9 construction along the wetland boundaries so that heavy equipment will not be operated or parked in the wetland during demolition and construction. In terms of mitigation for loss of functional buffer, the changes that the applicant made to the site plan increased the amount of impervious surface coverage proposed and consequently the amount of mitigation that may be required by the Village Code. The applicant proposes to do mitigation plantings and will also remove invasive species and debris in the wetland and buffer. Mrs. Timpone-Mohamed explained that if there isn't enough space on the property to install wetland and buffer plantings in the 2 to 1 ratio required by the Village Code, then removal of invasive plant species and debris may be considered by the Board as additional mitigation. In their discretion, the Planning Board can deem this sufficient. She added that the applicant needed to clearly delineate where they plan on doing the planting and the clean up on a plan. Mr. Goodman asked if there were storm water issues. Mr. Nowak noted that Mr. Dolph Rotfeld, Village Consultant, will be reviewing the plans. He noted that this area has always had a storm water issue. Mr. Goodman noted that the wetlands that exist are disturbed wetlands. Mr. Accurso asked how many times you must remove the invasive species. Mrs. Timpone-Mohamed noted that the cleanup of invasive species from property takes quite a bit of work. Removing the invasive species will give the native species the ability to fill in and flourish. Mrs. Timpone-Mohamed was asked to read a resolution setting a date for a public hearing on the matter: May 14, 2015 RESOLUTION SETTING A PUBLIC HEARING CONCERNING AN APPLICATION FOR SITE PLAN APPROVAL AND A WETLANDS PERMIT FOR 8 EDGEWOOD DRIVE VILLAGE OF RYE BROOK PLANNING BOARD Planning Board Meeting May 14,2015 Page 10 WHEREAS, 8 Edgewood Drive, LLC, on behalf of Frank Chiarello, property owner, submitted an application for approval of a site plan and a Permit to Perform Regulated Activities in a Wetland to demolish the existing single-family home and construct a new single-family home, rear patio, driveway, parking court and curb cut at 8 Edgewood Drive in the R-25 District, Section 135.28, Block 1, Lot 28 as shown on the Town of Rye Tax Assessor's Map. NOW, THEREFORE, BE IT RESOLVED, that the Village of Rye Brook Planning Board shall hold a Public Hearing on June 11, 2015 at 7:30 p.m., at Village Hall, 938 King Street, Rye Brook, New York to consider the application for site plan approval and a Permit to Perform Regulated Activities in a Wetland; and BE IT FURTHER RESOLVED, that the Planning Board, pursuant to the State Environmental Quality Review Act (SEQRA) determines the Proposed Action to be a Type 2 Action requiring no further review pursuant to the requirements of SEQRA; and BE IT FURTHER RESOLVED, that the Applicant is directed to comply with Section 250-40 of the Village Code regarding notification. On a motion made by Amy Schoen, and seconded by John Grzan, the roll was called, and the resolution setting the public hearing was approved.

July 6, 2015 Village of Rye Brook Planning Board 938 King Street Rye Brook,NY 10573 ATTN: Gary Zuckerman, Chair RE: Site Plan 8 Edgewood LLC 8 Edgewood Drive Sheet: 135.38 Blk: 1 Lot: 28 Dear Members of the Board: On behalf of our client,please find enclosed the following for your review and approval: • 11 Sets—Site Plan, last revised 7-1-2015 • 11 Sets—Tree Preservation and Protection Plan,last revised 7-1-2015 • 11 Sets—Details,last revised 7-1-2015 • 2 Engineer's Report,last revised 7-6-2015 • 1 Electronic Set of Plans We offer the following responses to the memo from Dolph Rotfeld Engineering,P.C.dated July 1,2015. 1. The HydroCAD model has been revised by removing the exfiltration rate.The size of the system remains functional and peak runoff rates in post development remain the same as previously submitted.The percolation test results provided are for documentation that the area being used is viable for this stormwater practice. 2. The proposed on site stormwater treatment system captures new impervious surfaces to the greatest extent possible.The infiltration system is designed to capture and store the total volume of runoff for the 25-year storm from the proposed residence. Due to site constraints (wetlands, elevations,etc.),the remaining impervious surfaces are not able to be treated onsite but are captured and accounted for in the pre versus post development peak flow analysis. 3. The Proposed Yard Drain#2 Detail can be found on the Details sheet. 4. The Proposed Yard Drain#1 has been lowered 6 inches,but will remain above the low point to maintain the natural hydrologic conditions of the wetland. 5. The Stone Retaining Wall Detail has been revised to accurately depict the proposed conditions. Site Design .

A Timber Rail has been provided on the edge of the driveway. 7. The wall has been moved 4 feet from the edge of the driveway with some minor grading to shorten the wall to 2 feet high.This will eliminate any vehicle loading from the driveway on the wall. A wall of such minimal height does not require a building permit per NYS Building Code. We believe we have addressed the comments from the Consulting Engineer's September 15,2014 Memo and the subsequent July 1, 2015 Memo to the greatest extent possible prior to the continuation of the Public Hearing.We look forward to closing the Public Hearing on July 9,2015 and hope a Resolution,can be adopted.

The site is located on the northeast side of Edgewood Drive and is surrounded by residential development. Currently there is an existing single family residence served by an asphalt driveway, an individual septic system, and public water system. No stormwater treatment system exists at the site. The site consists of a hillside slope which transitions down to a mildly sloped area where the existing residence is located. The soils on the property consist primarily of Woodbridge and Paxton loams which belong to hydrologic group C. A soil map has been provided herewith. A wetland forms a"U" shape around the house and discharges into the roadside drainage system. The site is located within the Long Island Sound Watershed. The applicant is proposing to remove the existing house and construct a new single family residence along with relocating the access driveway. Connecting to the existing public sewer and water systems will be required. The proposed site disturbance is 0.4 acres. A stormwater infiltration system is proposed to treat stormwater from the roof drains of the residence. A yard drain with a hooded outlet and sump will serve as the pre-treatment device and will also include an overflow pipe to by-pass storms larger than the 25-year storm. The infiltration system consists of 12 Cultec Recharger 330XLHD chambers situated in a gravel bed. Details for all the drainage improvements can be found on the plan. This system is sized to capture and store the 25-year storm generated by HYDROCAD. The overflow pipe from the yard drain outlets through the proposed drain manhole which is connects to the existing catch basin on Edgewood Drive to the south. The site, as it exists, contains 3,076 sq.ft. of untreated impervious surfaces. The proposed development will create 3,792 sq.ft. of impervious surfaces of which 2,098 sq. ft. is able to be captured and treated in the stormwater treatment system.

WdA Woodbridge loam,0 to 3 C 1.1 95.6% —{ Totals for Area of Interest percent slopes I� 1.1 100.0% Description Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups(A, B, C, and D)and three dual classes(A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate(low runoff potential)when thoroughly wet. These consist mainly of deep,well drained to excessively drained sands or gravelly sands.These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep,moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture.These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet.These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture.These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate(high runoff potential)when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group(A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. Rating Options Aggregation Method.

As per the Village of Rye Brook Zoning Code, Chapter 209, "Site Plan Review", please see below for issue(s) that will need response: 1. Runoff from the proposed driveway must not flow into the street. Based on the existing grade at the property line (202.26) it is not clear why a trench drain cannot be installed to pipe runoff to the proposed infiltration system (invert 198.50). 2. Runoff from the driveway must be accounted for in the infiltration system design for "total volume storage." It appears that the system is only sized for runoff from the proposed house (catchment P-1). 3. A detail must be provided for Proposed Yard Drain #2 demonstrating all pipe invert elevations and all pipe connection locations. Only two (2) pipe connections have been provided in the detail whereas the site plan shows four (4). A plan view of Yard Drain #2 must be provided as well as this will be the control structure of the infiltration system. Plans have not been reviewed by this office for zoning compliance. C: G.

As per the Village of Rye Brook Zoning Code, Chapter 209, "Site Plan Review", please see below for issue(s) that will need response: 1. The HydroCAD model applies the "in/hr" exfiltration rate over each square foot of surface area whereas the "in/hr" rate measured in the percolation test is the result of exfiltration over the entire surface area of the percolation test hole which appears to be more than 7 square feet. The "in/hr" rate measured during the percolation test must be reduced to a unit value such as "in/hr/square foot" before being used in HydroCAD. 2. Runoff from the proposed driveway must be captured with volume accounted for in the "total volume storage" stormwater mitigation design. 3. A detail must be provided for Proposed Yard Drain #2 demonstrating pipe invert elevations, pipe connection locations and where the trap/hood is proposed. 4. The proposed grading and retaining wall along the north side of the driveway appear to have created a low spot where ponding is likely to occur. It is recommended that Proposed Yard Drain #1 be lowered to provide drainage for this area. 5. The retaining wall detail must be revised to accurately demonstrate the proposed condition of a paved driveway behind it. 6. Protection should be provided along the top of the proposed retaining wall to prevent cars from going over the top of the wall.

Izzo ATTACHMENT EAF PART 3, NEGATIVE DECLARATION REASONS SUPPORTING THIS DETERMINATION ZONING PETITION, SUBDIVISION AND SITE PLAN APPLICATIONS BOWMAN PLAZA, 80 BOWMAN AVENUE, VILLAGE OF RYE BROOK, N.Y. Description of the Property The 21,982.06 square-foot subject property, located at 80 Bowman Avenue is comprised of three existing building lots, and is located in the FAH District, Section 141.27, Block 1, Lots 26, 31, and 32 on the Town of Rye Tax Map. The property was added to the FAH District when the Rye Brook Board of Trustees received a petition from the property owner, and subdivision and site plan applications to construct a 16-unit development that was approved on November 27, 2012 by the Board of Trustees. The FAH District zoning and development site plan approval remain in effect at this time; however, the subdivision plat combining the lots that comprise the property was not filed with the Westchester County Clerk's Office, so the subdivision approval expired. Tax Lot 26, which is 14,128.19 square feet, was developed, but is currently vacant, and Tax Lots 31 and 32, 4,173.21 square feet and 3,680.07 square feet respectively, are each developed with a one and one-half-story, single-family residence that would be demolished. Each of the lots has an existing curb cut on Barber Place. The corner lot, Lot 26, currently does not have a curb cut on Bowman Avenue. The three lots slope to the west away from the elevation of Bowman Avenue and there are mature landscape plants and naturalized trees and shrubs on all three lots. Description of the Proposed Action Bowman Plaza, LLC (Frank Madonna), property owner, submitted a petition to rezone the property into the Cl District, zoning text amendments, and applications for approval of a subdivision (lot merger) and a site plan to construct a three-story mixed-use retail/residential building. As originally submitted the mixed-use building consisted of 4,100 square feet of ground-floor retail space, and 19 residential apartments, with a total of 44 parking spaces located under the building and in two street-level parking areas on the subject property located at the southeast corner of the intersection of Bowman Avenue and Barber Place. Construction also would include stormwater management I facilities, site lighting, a curb cuts on Bowman Avenue and Barber Place, pedestrian walkways and public sidewalks, landscaping and other new associated site features. The Applicant revised the Proposed Action to respond to the concerns and comments received from the Planning Board and its consultants, and the Village of Rye Brook staff. The Applicant's finally revised Proposed Action would construct a three-story mixed-use building consisting of 2,400 square feet of ground-floor retail space and a total of 16 apartments, with 38 parking spaces located under the building and in two street-level parking areas. The residential component of the development would include eight one- bedroom and eight two-bedroom apartments. Each apartment includes a 64 square-foot balcony or terrace. The revised Proposed Action also includes a subdivision application to combine the lots that comprise the property required by Section 250-6 A. (2) (a) of the Rye Brook Code, and a petition to the Board of Trustees to amend the Zoning Map of the Village to remove the property from the FAH District and include the property within the Cl District. However, the revised Proposed Action no longer includes a request for zoning text amendments of the C1 District. Instead, the Applicant requests certain variances from the C1 District regulations from the Rye Brook Zoning Board of Appeals. The revisions to the site plan also include a mountable-curb emergency entrance into the site from Barber Place, which will allow fire engine aerial access to the building. The revised site plan eliminates the vehicular exit from the parking area adjacent to Bowman Avenue onto Barber Place and one parking space to allow cars in the parking area to turn around and exit onto Bowman Avenue using the same curb cut as the entrance to the site from Bowman Avenue. Evaluation of Potential Impacts Review of the Full Environmental Assessment Form (EAF) and additional information provided by the Applicant, and completion of Part 2 of the EAF demonstrated that there are no potential adverse impacts from the Proposed Action with respect to geologic features, surface water, ground water flooding, air, plants and animals, agricultural resources, aesthetic resources, historic and archeological resources, open space and recreation, a Critical Environmental Area, and consistency with community character, primarily because the Proposed Action is located in a developed neighborhood on already developed lots. Any temporary impacts to air and water during construction will be limited by the implementation of a construction management and logistics plan and use of best practices with respect to demolition, construction and erosion and sediment control. 2 Certain small to moderate potential impacts related to rezoning the subject property and the development plan for the Proposed Action were identified in Part 2 of the EAF. These impacts include: 1. potential impacts to land regarding construction on improved and vacant land, and alteration of storm water run-off regarding the potential for increased run-off from new impervious surfaces; 2. impacts to transportation systems regarding the potential for increased traffic and parking demand; 3. increased energy demand; 4. impacts to public health and safety regarding the potential presence of hazardous subsurface materials; and 5. consistency with community plans. The assessment in Part 2 of the EAF identified that there may be potential adverse impacts from the Proposed Action with respect to land, transportation and parking, energy, and human health and safety as follows: 1. Land. The Proposed Action involves the demolition of existing buildings, the clearing and excavation of land, and the construction of new buildings and site improvements that have the potential to cause erosion. However, a stormwater management plan, and construction management and logistics plan that includes erosion and sediment control will be implemented during construction to limit any minor impacts to land that may occur. Existing vegetation that is removed will be replaced by new landscape material. The property was developed in the past and it is located in a fully developed area of Rye Brook. The new residential/retail building would be landscaped and maintained similarly to other occupied properties in the neighborhood. The site plan includes a landscape plan that would help to mitigate the visual impact of the proposed building and the proposed building height. The tree preservation plan would protect as many existing mature trees as is practical, and the landscape plan includes replacement trees for those trees to be removed. The construction management plan would include best management practices to eliminate or reduce any impacts related to removal of vegetation, grading, and excavation, including erosion and sediment control, traffic control, and creation of noise and airborne dust during construction. Increased run-off from new impervious surfaces will be mitigated by the development and implementation of a post-construction stormwater management plan for the site. 2. Transportation and Parking. Concerns regarding the impact of increased residential and commercial traffic were analyzed by a traffic impact study provided by the Applicant and reviewed by the Planning Board and its consultants. 3 Housing more people on the lot and adding retail space would increase vehicular traffic in the local area, which may impact current local traffic conditions by increasing traffic congestion. However, the increase in traffic may be reduced compared to what it would be in other areas of Rye Brook because the development would be located within walking distance to schools, shopping and public transportation, which reduces the need to use a car for many of residents' daily errands and destinations. Although it is anticipated that the development would generate additional traffic, the level of additional traffic is not expected to have a significant impact on area roads; however, there may be minor increases in the traffic congestion on Barber Place and Franklin Street. A parking demand study and shared parking analysis provided by the Applicant and reviewed by the Planning Board's consultant indicated that the number of parking spaces proposed would be sufficient to accommodate the increased parking demand generated by the Proposed Action. Any temporary impacts to transportation and parking during construction will be limited by the implementation of a construction management and logistics plan and at a minimum compliance with the requirements of the Rye Brook Code with respect to construction scheduling and working hours. 3. Energy. The construction of the mixed-use building would create an increase in the demand for electrical energy; however, the expected increase for 16 new apartments and a 2,400 square-foot retail use would be a relatively small impact to the existing resources of the local utility. 4. Human Health and Safety. All of the building lots that comprise the subject property were developed in the past, and dwellings are currently situated on the two tax lots that front on Barber Place. The buildings on the remaining building lots that comprise the tax lot situated at the corner of Barber Place and Bowman Avenue were demolished some time ago, so this portion of the property is currently vacant. The two existing homes and the home that was demolished may have caused the deposition of unknown hazardous materials on the site. In addition, the property is adjacent to a dry cleaning business and a former automotive service station, two enterprises that are known to use hazardous materials in the conduct of business that could migrate underground to the subject property from leaking storage containers or spills. A Phase 1 Investigation regarding the potential for hazardous materials was performed. The Phase 1 Report indicated there is potential for hazardous materials on the site based on the presence of older homes on the lots and the proximity of 4 the property to sites where there is known hazardous material use and documented spills of hazardous substances. Therefore, a Phase 2 Subsurface Soil Investigation that included soil and ground water sampling and testing for suspected substances was conducted. The Phase 2 Investigation Report indicates that contamination from adjacent sites has not migrated onto the subject property. The Phase 2 Investigation Report was reviewed by the Village's technical engineering consultant, HDR that provided a report dated November 21, 2012. None of the suspected compounds were found on the subject property in any sample tested with the exception of one ground water sample that indicated the presence of acetone. However, the presence of acetone may be a laboratory artifact. The reporting of levels of acetone in samples tested in laboratories is common. As the municipal water supply will provide potable water to the development, the presence of acetone in the water is not considered a significant hazard. Any temporary impacts related to the handling and disposal of hazardous materials during construction will be limited by the implementation of a construction management and logistics plan that includes dust, and air quality monitoring, a Health and Safety Plan for the construction site, and use of best practices with respect to demolition and hazardous materials handling and disposal during construction. The construction management plan will include discussion regarding potential construction impacts and proposed mitigation measures, that will include, but not be limited to, compliance with local regulations, demolition, phasing, estimated construction traffic and construction parking arrangements, noise impacts, air quality protection, materials delivery, storage and staging, hazardous materials handling, a site safety plan, public safety precautions to be implemented, etc. 5. Consistency with Community Plans. The property is located in a fully developed area of Rye Brook and on lots that were developed in the past. The new residential/retail building would be landscaped and maintained similarly to other occupied properties in the neighborhood. The Westchester County Planning Board has determined the Proposed Action to be generally consistent with the Westchester County Planning Board's long range planning policies as set forth in "Westchester 2025." Though the Proposed Action includes a set back and parking along the Bowman Avenue frontage, which are inconsistent with Westchester County policies, in this case, the Proposed Action is located on a lot situated between a residential area and a commercial area that can support a mixed-use commercial/residential building with a similar setback and parking pattern to the surrounding existing commercial and residential buildings, 5 so as to act as a transition between the existing residential properties to the east and the existing commercial properties to the north and west. Although the proposed apartments are larger than recommended, and the building is setback from the street, the Proposed Action is generally consistent with the recommendations of the Rye Brook Comprehensive Plan in that it is a mixed-use building with increased density and height. It has a limited number of parking spaces because the parking spaces are shared between two proposed uses reducing the total number of spaces required. It ties into and improves the public pedestrian circulation system by providing public sidewalks on Barber Place and Bowman Avenue. It complies with the allowable FAR of the Cl District and adds to the available housing choices in Rye Brook. The proposed building was designed to be compatible in appearance and exterior design with other buildings in the surrounding existing neighborhood. 6 Full Environmental Assessment Form Part Z-Identification of Potential Project Impacts Part 2 is to be completed by the lead agency. Part 2 is designed to help the lead agency inventory all potential resources that could be affected by a proposed project or action. We recognize that the lead agency's reviewer(s)will not necessarily be environmental professionals. So,the questions are designed to walk a reviewer through the assessment process by providing a series of questions that can be answered using the information found in Part 1. To further assist the lead agency in completing Part 2,the form identifies the most relevant questions in Part 1 that will provide the information needed to answer the Part 2 question. When Part 2 is completed,the lead agency will have identified the relevant environmental areas that may be impacted by the proposed activity. If the lead agency is a state agency and the action is in any Coastal Area,complete the Coastal Assessment Form before proceeding with this assessment. Tips for completing Part 2: • Review all of the information provided in Part 1. • Review any application,maps, supporting materials and the Full EAF Workbook. • Answer each of the 18 questions in Part 2. • If you answer"Yes"to a numbered question,please complete all the questions that follow in that section. • If you answer"No"to a numbered question,move on to the next numbered question. • Check appropriate column to indicate the anticipated size of the impact. • Proposed projects that would exceed a numeric threshold contained in a question should result in the reviewing agency checking the box"Moderate to large impact may occur." • The reviewer is not expected to be an expert in environmental analysis. • If you are not sure or undecided about the size of an impact,it may help to review the sub-questions for the general question and consult the workbook. • When answering a question consider all components of the proposed activity,that is,the"whole action". • Consider the possibility for long-term and cumulative impacts as well as direct impacts. • Answer the question in a reasonable manner considering the scale and context of the project. 1.

Description of the Property The 21,982.06 square-foot subject property, located at 80 Bowman Avenue is comprised of three existing building lots, and is located in the FAH District, Section 141.27, Block 1, Lots 26, 31, and 32 on the Town of Rye Tax Map. The property was added to the FAH District when the Rye Brook Board of Trustees received a petition from the property owner, and subdivision and site plan applications to construct a 16-unit development that was approved on November 27, 2012 by the Board of Trustees. The FAH District zoning and development site plan approval remain in effect at this time; however, the subdivision plat combining the lots that comprise the property was not filed with the Westchester County Clerk's Office, so the subdivision approval expired. Tax Lot 26, which is 14,128.19 square feet, was developed, but is currently vacant, and Tax Lots 31 and 32, 4,173.21 square feet and 3,680.07 square feet respectively, are each developed with a one and one-half-story, single-family residence that would be demolished. Each of the lots has an existing curb cut on Barber Place. The corner lot, Lot 26, currently does not have a curb cut on Bowman Avenue. The three lots slope to the west away from the elevation of Bowman Avenue and there are mature landscape plants and naturalized trees and shrubs on all three lots. Description of the Proposed Action Bowman Plaza, LLC (Frank Madonna), property owner, submitted a petition to rezone the property into the Cl District, zoning text amendments, and applications for approval of a subdivision (lot merger) and a site plan to construct a three-story mixed-use retail/residential building. As originally submitted the mixed-use building consisted of 4,100 square feet of ground-floor retail space, and 19 residential apartments, with a total of 44 parking spaces located under the building and in two street-level parking areas on the subject property located at the southeast corner of the intersection of Bowman Avenue and Barber Place. Construction also would include stormwater management I facilities, site lighting, a curb cuts on Bowman Avenue and Barber Place, pedestrian walkways and public sidewalks, landscaping and other new associated site features. The Applicant revised the Proposed Action to respond to the concerns and comments received from the Planning Board and its consultants, and the Village of Rye Brook staff. The Applicant's finally revised Proposed Action would construct a three-story mixed-use building consisting of 2,400 square feet of ground-floor retail space and a total of 16 apartments, with 38 parking spaces located under the building and in two street-level parking areas. The residential component of the development would include eight one- bedroom and eight two-bedroom apartments. Each apartment includes a 64 square-foot balcony or terrace. The revised Proposed Action also includes a subdivision application to combine the lots that comprise the property required by Section 250-6 A. (2) (a) of the Rye Brook Code, and a petition to the Board of Trustees to amend the Zoning Map of the Village to remove the property from the FAH District and include the property within the Cl District. However, the revised Proposed Action no longer includes a request for zoning text amendments of the C1 District. Instead, the Applicant requests certain variances from the C1 District regulations from the Rye Brook Zoning Board of Appeals. The revisions to the site plan also include a mountable-curb emergency entrance into the site from Barber Place, which will allow fire engine aerial access to the building. The revised site plan eliminates the vehicular exit from the parking area adjacent to Bowman Avenue onto Barber Place and one parking space to allow cars in the parking area to turn around and exit onto Bowman Avenue using the same curb cut as the entrance to the site from Bowman Avenue. Evaluation of Potential Impacts Review of the Full Environmental Assessment Form (EAF) and additional information provided by the Applicant, and completion of Part 2 of the EAF demonstrated that there are no potential adverse impacts from the Proposed Action with respect to geologic features, surface water, ground water flooding, air, plants and animals, agricultural resources, aesthetic resources, historic and archeological resources, open space and recreation, a Critical Environmental Area, and consistency with community character, primarily because the Proposed Action is located in a developed neighborhood on already developed lots. Any temporary impacts to air and water during construction will be limited by the implementation of a construction management and logistics plan and use of best practices with respect to demolition, construction and erosion and sediment control. 2 Certain small to moderate potential impacts related to rezoning the subject property and the development plan for the Proposed Action were identified in Part 2 of the EAF. These impacts include: 1. potential impacts to land regarding construction on improved and vacant land, and alteration of storm water run-off regarding the potential for increased run-off from new impervious surfaces; 2. impacts to transportation systems regarding the potential for increased traffic and parking demand; 3. increased energy demand; 4. impacts to public health and safety regarding the potential presence of hazardous subsurface materials; and 5. consistency with community plans. The assessment in Part 2 of the EAF identified that there may be potential adverse impacts from the Proposed Action with respect to land, transportation and parking, energy, and human health and safety as follows: 1. Land. The Proposed Action involves the demolition of existing buildings, the clearing and excavation of land, and the construction of new buildings and site improvements that have the potential to cause erosion. However, a stormwater management plan, and construction management and logistics plan that includes erosion and sediment control will be implemented during construction to limit any minor impacts to land that may occur. Existing vegetation that is removed will be replaced by new landscape material. The property was developed in the past and it is located in a fully developed area of Rye Brook. The new residential/retail building would be landscaped and maintained similarly to other occupied properties in the neighborhood. The site plan includes a landscape plan that would help to mitigate the visual impact of the proposed building and the proposed building height. The tree preservation plan would protect as many existing mature trees as is practical, and the landscape plan includes replacement trees for those trees to be removed. The construction management plan would include best management practices to eliminate or reduce any impacts related to removal of vegetation, grading, and excavation, including erosion and sediment control, traffic control, and creation of noise and airborne dust during construction. Increased run-off from new impervious surfaces will be mitigated by the development and implementation of a post-construction stormwater management plan for the site. 2. Transportation and Parking. Concerns regarding the impact of increased residential and commercial traffic were analyzed by a traffic impact study provided by the Applicant and reviewed by the Planning Board and its consultants. 3 Housing more people on the lot and adding retail space would increase vehicular traffic in the local area, which may impact current local traffic conditions by increasing traffic congestion. However, the increase in traffic may be reduced compared to what it would be in other areas of Rye Brook because the development would be located within walking distance to schools, shopping and public transportation, which reduces the need to use a car for many of residents' daily errands and destinations. Although it is anticipated that the development would generate additional traffic, the level of additional traffic is not expected to have a significant impact on area roads; however, there may be minor increases in the traffic congestion on Barber Place and Franklin Street. A parking demand study and shared parking analysis provided by the Applicant and reviewed by the Planning Board's consultant indicated that the number of parking spaces proposed would be sufficient to accommodate the increased parking demand generated by the Proposed Action. Any temporary impacts to transportation and parking during construction will be limited by the implementation of a construction management and logistics plan and at a minimum compliance with the requirements of the Rye Brook Code with respect to construction scheduling and working hours. 3. Energy. The construction of the mixed-use building would create an increase in the demand for electrical energy; however, the expected increase for 16 new apartments and a 2,400 square-foot retail use would be a relatively small impact to the existing resources of the local utility. 4. Human Health and Safety. All of the building lots that comprise the subject property were developed in the past, and dwellings are currently situated on the two tax lots that front on Barber Place. The buildings on the remaining building lots that comprise the tax lot situated at the corner of Barber Place and Bowman Avenue were demolished some time ago, so this portion of the property is currently vacant. The two existing homes and the home that was demolished may have caused the deposition of unknown hazardous materials on the site. In addition, the property is adjacent to a dry cleaning business and a former automotive service station, two enterprises that are known to use hazardous materials in the conduct of business that could migrate underground to the subject property from leaking storage containers or spills. A Phase 1 Investigation regarding the potential for hazardous materials was performed. The Phase 1 Report indicated there is potential for hazardous materials on the site based on the presence of older homes on the lots and the proximity of 4 the property to sites where there is known hazardous material use and documented spills of hazardous substances. Therefore, a Phase 2 Subsurface Soil Investigation that included soil and ground water sampling and testing for suspected substances was conducted. The Phase 2 Investigation Report indicates that contamination from adjacent sites has not migrated onto the subject property. The Phase 2 Investigation Report was reviewed by the Village's technical engineering consultant, HDR that provided a report dated November 21, 2012. None of the suspected compounds were found on the subject property in any sample tested with the exception of one ground water sample that indicated the presence of acetone. However, the presence of acetone may be a laboratory artifact. The reporting of levels of acetone in samples tested in laboratories is common. As the municipal water supply will provide potable water to the development, the presence of acetone in the water is not considered a significant hazard. Any temporary impacts related to the handling and disposal of hazardous materials during construction will be limited by the implementation of a construction management and logistics plan that includes dust, and air quality monitoring, a Health and Safety Plan for the construction site, and use of best practices with respect to demolition and hazardous materials handling and disposal during construction. The construction management plan will include discussion regarding potential construction impacts and proposed mitigation measures, that will include, but not be limited to, compliance with local regulations, demolition, phasing, estimated construction traffic and construction parking arrangements, noise impacts, air quality protection, materials delivery, storage and staging, hazardous materials handling, a site safety plan, public safety precautions to be implemented, etc. 5. Consistency with Community Plans. The property is located in a fully developed area of Rye Brook and on lots that were developed in the past. The new residential/retail building would be landscaped and maintained similarly to other occupied properties in the neighborhood. The Westchester County Planning Board has determined the Proposed Action to be generally consistent with the Westchester County Planning Board's long range planning policies as set forth in "Westchester 2025." Though the Proposed Action includes a set back and parking along the Bowman Avenue frontage, which are inconsistent with Westchester County policies, in this case, the Proposed Action is located on a lot situated between a residential area and a commercial area that can support a mixed-use commercial/residential building with a similar setback and parking pattern to the surrounding existing commercial and residential buildings, 5 so as to act as a transition between the existing residential properties to the east and the existing commercial properties to the north and west. Although the proposed apartments are larger than recommended, and the building is setback from the street, the Proposed Action is generally consistent with the recommendations of the Rye Brook Comprehensive Plan in that it is a mixed-use building with increased density and height. It has a limited number of parking spaces because the parking spaces are shared between two proposed uses reducing the total number of spaces required. It ties into and improves the public pedestrian circulation system by providing public sidewalks on Barber Place and Bowman Avenue. It complies with the allowable FAR of the Cl District and adds to the available housing choices in Rye Brook. The proposed building was designed to be compatible in appearance and exterior design with other buildings in the surrounding existing neighborhood. 6 y FREDERICK P. CLARK ASSOCIATES, INC.

Property Description The 22,275 square-foot property, located in the R-12 zoning district on the north side of Bonwit Road, is currently developed with a two-story single- family residence with an attached garage. In addition to the residence, the property includes a driveway, parking court and curb cut, retaining walls and walkways. Mature landscape plantings are located throughout the property, which slopes down nine feet from the north east corner of the rear yard to the south west corner of the front yard. Areas of moderately steep to extremely steep slopes are located throughout the property. Project Description The Applicant proposes to demolish the existing home and construct a new two-story home with an attached two-car garage. A new parking court and driveway would be constructed where the existing garage and driveway are located. The new driveway would utilize the existing curb cut. A deck would be constructed adjacent to the new home in the rear yard. FREDERICK P. CLARK ASSOCIATES, INC. PLANNING, TRANSPORTATION, ENVIRONMENT AND DEVELOPMENT RYE, NEW YORK FAIRFIELD, CONNECTICUT Much of the property will be graded to eliminate existing retaining walls and re-design existing steep slopes in the rear and front yards. According to the tree removal application and the plans, 13 live regulated trees would be removed from the property during construction. New retaining walls, walkways, exterior stairs, landscape plantings, and storm water management facilities also would be installed.

We offer the following comments regarding the application: 1. Site Plan. The property includes an existing, low, retaining wall on the east side of the current driveway that is partially located in the Bonwit Road right-of-way. The proposed site plan indicates that the wall will be rebuilt to accommodate the new driveway alignment and that the new wall will also be located within the right-of- way. The site plan should be revised so that new retaining wall will be located wholly on the subject property and not within the right-of-way. 2. Grading Plan. The proposed grading plan would change the existing drainage patterns on the site sending stoirawater flow onto the adjacent property to the west. The grading plan and the stoirawater management system should be coordinated and designed to eliminate storrnwater flow onto adjacent properties. 3. Tree Removals. The site plan would require the removal of 14 regulated trees from the property. The trees to be removed range in size from 8 inches DBH to 25 inches DBH. The tree removals will require the installation of a number of new hardwood shade trees pursuant to Chapter 235 of the Village Code and review by the Village Engineer. Pending final determination by the Village Engineer, it appears that 14 two to two and a half inch caliper native, hardwood-shade replacement trees would be required to replace the trees removed. The proposed landscape plan includes only seven new native trees that would qualify as replacement trees. 3 FREDERICK P. CLARK ASSOCIATES, INC. PLANNING, TRANSPORTATION, ENVIRONMENT AND DEVELOPMENT RYE, NEW YORK FAIRFIELD, CONNECTICUT The Planning Board should determine if the planting plan should be revised to include an additional seven native, hardwood-shade replacement trees. In the event compliance with the full restoration requirement is determined to be impractical, and in this case it is our opinion that it would be, the Board may, as an alternative, require the Applicant to pay a restoration fee in lieu of any of the additional trees that it determines may not be practicably planted on the property. 4. Tree Preservation Plan. The tree protection detail located on Sheet 3 of 9 of the engineer's plans should be revised to show that the tree protection measures detailed will be installed at the drip line or lines of the tree or trees to be protected. The current detail would locate the protection only six feet from the trunk of a tree. Excavation for the west set of Cultec units would be located close to one of the trees to be preserved. If the Cultec units must be located as shown, we recommend removing the tree, as the excavation will severely damage the feeding and anchor roots of the tree, which will impact its long term viability and stability. The landscape plan, the tree removal permit and the number of replacement trees should be revised accordingly, if the tree is to be removed. 5. Landscape Plan. The landscape plan should be revised to list the correct number of trees required as replacements for trees to be removed. We look forward to review of the application and discussion by the Planning Board.

DEVELOPMENT REVIEW CHECKLIST WESTCHESTER COUNTY PLANNING BOARD Notice to Applicants/Developers: At some point during the development review process your project may be referred to the Westchester County Planning Board for review and comment in accordance with state and county laws that require local planning boards, zoning boards of appeals and governing bodies to refer certain development applications to the County Planning Board. Referral to the County Planning Board may not occur until your project has progressed well along through the design process. Since the Planning Board's comments may impact project design,this checklist is provided to encourage early consideration of these areas of concern by applicants to avoid project changes later. For information on the County Planning Board review process and to access an electronic copy of this checklist, go online to www.westchestergov.com/planningreferrals or contact Lukas Herbert at lah5@westchestergov.com. I. COUNTY PLANNING BOARD POLICIES: Written policies underlie all recommendations of the County Planning Board. Westchester 2025-Contez7 for County and Municipal Planning and Policies to Guide County Planning,adopted by the County Planning Board on 516108,amended 115110,can be found at ww.westchestergov.com/2025. ❑ Westchester 2025: Policies should be reviewed to determine how they relate to the development proposal. H.IWACTS TO COUNTY FACILITIES AND SERVICES: The County Planning Board coordinates the review of development projects with Westchester County departments to identify and address potential impacts on County services and infrastructure. In some situations, permits and approvals may be required that could change project design. Site Plan Checklist Page 4 of 7 Project Address jT _Kp ❑ Map of County Facilities: Review the State & County Roads and Parks map (which also includes county channel lines)to identify proximity to County facilities at: www.westchestergov.com/planningdocs/pdfmaps/countystateroadsparks.pdf. Other useful map links for information about environmental features, septic/sewer map, county sewer districts map, etc can be found at: www.westchestergov.com/maps ❑ COUNTY ROAD: Applications for development on sites that abut a County road must be submitted for review by the County Department of Public Works. Information and forms can be found at: www.westchestergov.com/dpw/bidgperm.htm. Former County Roads do not need review by the Department of Public Works,but will still likely trigger a review by the County Planning Board. ❑ COUNTY CHANNEL LINES: Applications for development on sites within 100 feet of a designated County Channel Line require a stream control permit from the County Department of Public Works. Information and forms can be found at: ,,vww.westchestergov.com/dpw/bidgperm.htm ❑ COUNTY PARK: New construction & land alteration projects adjacent to County parks are expected to address screening & buffer of new uses from the park, as appropriate. Stormwater should not drain from a developed site onto a County park without acceptable quantity and quality controls. County parks are designated as Critical Environmental Areas. ❑ SEWAGE TREATMENT AT COUNTY TREATMENT PLANT: Local municipalities are required to reduce and eliminate inflow and infiltration(I&I)into the sanitary sewage systems tributary to County treatment plants.New development will be expected to reduce I&I in relation to generation of new flow at a ratio of three to one. This requirement must be discussed with local officials. ❑BEE-LINE BUS SERVICE: Bee-Line bus stops serving a development site should be identified on plans or noted if located off-site. If a bus stop is located along the site's frontage, the applicant should contact the County Department of Transportation to discuss impacts and the need for improvements. Safe and separate pedestrian access should be provided to link a bus stop and sidewalk with building entrances. Information on County bus service and design guidelines can be found at: westchestergov.com transportation/images/Bus°/o20Service°/`2OGuidelines.pdf ❑FAIR AND AFFORDABLE HOUSING: Many municipalities require inclusion of fair & affordable units in new developments. Financial assistance to achieve fair & affordable housing development is available through Westchester County & other sources. Applications that include new residential units to be affirmatively marketed & sold or rented subject to fair& affordable housing provisions should be tied to Westchester County guidelines on affordability including income guidelines of eligible households that can be found at: http://homes.westchestergov.com/. If County funding is sought to develop fair & affordable housing,the County Board of Legislators must be included as an involved agency under SEQR. ❑RECYCLING: New buildings must contain a designated area of sufficient size for separation and storage of recyclables and trash. Building expansions should also include sufficient space for separation and storage of recyclables. For more information about County recycling requirements go to: www.westchestergov.com/environment-Yecycling.htm ❑STORM SEWER SYSTEM: Any connections to a County storm sewer line will require a permit from the Department of Public Works in accordance with the County Illicit Discharge Detection and Elimination (IDDE) law. Information & forms can be found at:www.westchestergov.com/dpwlbldgperm.htm Non-stormwater discharges to the County storm sewer system are prohibited. III.DEVELOPMENT STANDARDS The County Planning Board's land use policies focus attention on several aspects of development that may have intermunicipal and quality of life impacts. The list below includes areas most frequently commented on by the County Planning Board. ❑WATER: All development plans should include sufficient provisions for stormwater management, water quality measures and mitigation of flooding. ❑Plans should identify the major drainage basin or watershed the site is located in (Croton River, Upper Hudson River, Lower Hudson, Upper Long Island Sound, Bronx River and Lower Long Island Sound). An interactive map with watershed boundaries can be found at www.westchestergov.com/planning/maps&lists/drainbasins]Ixl7.htm1 ❑Watershed plans have been developed for several of the County's watersheds - the Croton, Indian Brook-Croton Gorge, Bronx River & Long Island Sound watersheds - that include specific recommendations that apply to development projects. See recommendations in watershed plans at:planning.westchestergov.com/index.php?option=com_content&task view&id= 1231& Item id=2204 Site Plan Checklist Page 5 of 7 Project Address, 5 hp"Lla 1.0 ❑Development that involves filling, creation of impervious surfaces or buildings and substantive loss of natural vegetation in a floodplain or flood prone area should be avoided. ❑Above ground,vegetated retention/detention basins or devices are preferred because they perform better,are easier to inspect and maintain and provide additional environmental benefits over subsurface structural devices. Any such treatments should not be constructed within wetlands or buffer areas around wetlands. ❑The development should treat and retain as much stormwater on-site as possible,particularly when the site is located in a drainage basin with known flooding problems. A Construction Stormwater Toolbox with tools and sources of technical information related to the construction activities and stormwater management best practices is available from the New York State Department of Environmental Conservation at:www.dec.ny.gov.%chemical/8694.html ❑New development should include protection of aquatic resources. For more information about protection of aquatic resourc-es & buffer areas,go to: planning.westchestergov.com/index.php?option=com_content&task=view&id=1491&Itemid=2458 ❑Impervious cover should be minimized. Permeable paving surfaces should be used where feasible. Vegetative rain gardens should be used, particularly in areas of overland or channelized stormwater flow,to improve stormwater quality and reduce runoff volume. For more information,go to: www.westchestergov.com/stormwater ❑Buildings along coastlines and low lying area should consider the impacts of sea level rise. Specific consideration is required of potential impacts to surface and subsurface drinking water supplies. ❑ SITE LAYOUT.Aesthetic design,building orientation and community character should be considered in the site layout and building appearance. []In most locations,buildings should face the street and have pedestrian access from the street. El Commercial buildings should be located near the front street line with the majority of parking located in the rear of the building. Even gas stations and convenience stores should be upfront in a landscaped setting with parking,pumps and canopy toward the rear. El Buildings should be of pedestrian-scale when seen from the sidewalk. ❑Building facades should contribute to and enhance the character of the community. ❑Driveway and pathway connections should be provided to adjacent sites when possible and crosseasements provided. ❑ STREETS. Street design should reduce unwarranted paving and promote connectivity. ❑New streets should connect with adjacent streets wherever feasible to prevent the proliferation of dead-end streets and promote neighborhood integration. El Connections could be vehicular or pedestrianibicycle only,where appropriate. ❑Street widths should be minimized for streets with low traffic volume to reduce speeds and impervious surfaces. Lane widths of 12 feet are only appropriate for major roadways. []Driveway widths should be no more than 9 feet to reduce impervious surfaces. ❑Permeable paving surfaces should be used where feasible. ❑ GREEN TECHNOLOGY.New development should include as many green building elements as possible, such as:renewable building materials,energy efficient heating/cooling systems and fixtures,water saving devices,green roofs and permeable paving surfaces. Information can be obtained from the U.S. Green Building Council at:www.usgbc.org. ❑ LANDSCAPING AND LIGHTING.The site improvements should enhance community character. Site Plan Checklist Page 6 of 7 Project Address _11Z �t ❑ Landscaping should consist of native plant species appropriate for the location.Invasive plant species should be prohibited. Invasive plant information available at:www.westchestergov.com/planning/environmentaVReports/InvasivePlantsBrochO8.pdf ❑ Pollutant tolerant plantings should effectively shield parking,loading areas and refuse collection sites. ❑ Site lighting should be provided at the lowest safe levels and lowest heights,avoiding all spillage off site. ❑ PEDESTRIANS. Safe,convenient and ADA accessible pedestrian access is provided. ❑ A sidewalk should be provided along the site frontage along each street. ❑ Direct pedestrian connections should be made from the front of the building to the sidewalk.Pedestrian crossings of drive-ways& parking lots should be minimized or avoided. if they must be provided,painted crosswalks should be provided through parking lots. ❑ ADA accessibility must be provided. ❑ BICYCLISTS.Provisions for bicyclists should be incorporated into project design. ❑ Bicycle parking should be provided in commercial and residential developments. Guidelines can be found at: www.apbp.org/resource/resmgr/publications/bicycle_parking_guidelines.pdf ❑ If near a trailway or bicycle route,extra consideration should be given to bicycle accessibility such as bike lanes on internal roadways,bicycle parking and other amenities. ❑ Drive-thru lanes at uses such as banks and fast-food restaurants should also be accessible for bicycles. Waiver: Upon finding by the Building Inspector, Village Engineer, Planning Board or Board of Trustees that, due to the particular character or limited nature of development or change in use or to special conditions peculiar to a site,the submission of a final site plan, or certain portions of information normally required as part of the site development plan, is inappropriate or unnecessary or that strict compliance with said submission requirements will cause extraordinary and unnecessary hardship, such official or Board may waive such submission requirements wherever, in the opinion of such official or Board, such waiver will be consistent with the goal of promoting the public health, safety and general welfare of the community. The findings for granting such waiver shall become a part of the public record. Any waiver request must be made in writing, and include sufficient detailed information for the appropriate authority to make an informed decision.

Feet HEIGHT/SETBACK RATIOS FOR RESIDENTIAL DISTRICTS DEFINITION: A standard designed to regulate the height of a building in relation to the average grade of the corresponding portion of the lot line from which it is set back. The ratio modifies the maximum permitted Height of Building by forming an inclined plane beginning at the average grade along the portion of the lot line from which the setback is measured and rising toward the building at the specified ratio above which no part of any building, other than minor architectural features such as chimneys, skylights and dormer windows not covering more than 10% of the entire roof area,shall be permitted to extend. Height and Setback shall be calculated using the formula; Height/Setback =X, where X is the required side or front yard ratio for the zoning district in which a property is located as specified in Article VIII of Chapter 250. A complete elevation view for the proposed improvement must be included on the drawings.

The building foot print of the proposed home is 3,438.39 square feet including the rear deck, area way, front covered porch, and all landings and steps. The proposed residence will be serviced by public water supply and sanitary sewer. The residence and associated improvements within the property's limits have been designed to provide a zero net increase in the amount of storm water discharging from the property for a 25-year, 24-hour storm event. STEEP SLOPES: The property was evaluated using the steep slopes criteria listed in the current Village of Rye Brook zoning code and the analysis revealed the following: Total Lot Area=22,275 ft' Total Proposed Site Disturbance= 21,313.80 ft2 Description: Existin Areas ft2Proposed Disturbance ft2 Non-steep slopes < 15% 17,883.18 16,921.98 Moderate steep slopes 3,991.79 3,991.79 (15%- 25%) Very steep slopes 285.00 285.00 (25%- 35%) Extreme steep slopes (> 35%) 115.03 115.03 Totals: 22,275.00 21,313.80 1 SANITARY SERVICE CONNECTION: The residence will be connected to the existing sanitary service lateral that serviced the existing residence. The existing portion of the service lateral from the proposed point of connection to the public sanitary main in Bonwit Road will be inspected by means of CCTV to verify the condition prior to final connection. WATER SERVICE CONNECTION: The residence will be connected to the existing water service curb valve previously installed adjacent to the south property line. The service from the house will be connected to the existing curb valve. The Plumbing Contractor shall verify, at the time of construction, that the lateral from the curb box to the public water main in Bonwit Road is in good working condition. STORM WATER MANAGEMENT: Pre-Development Conditions: The site consists of several structures and features that are to be demolished and removed prior to construction of the proposed residence and associated improvements. The following is a list of existing structures and features and their respective areas of impervious surface: - House, front porch, garage,landings, and steps—3,217.95 Sq. Ft. - Front walkway—266.79 Sq. Ft. - Asphalt and concrete driveway— 1,688.77 Sq.Ft The above sum of existing impervious surfaces located entirely within the property limits is 5,173.51 square feet. To model the existing conditions of the site, as per Village of Rye Brook Code, the entire lot (22,275 Sq. Ft.) was evaluated using a runoff curve number of 61 and a time of concentration of 9.0 minutes, taking no credit for the existing impervious surfaces. A hydrological analysis of the property in this state revealed that the net runoff from the site is 1.03 ft3/sec during a 25-year,24-hour storm event. Post Development Conditions: The following is a list of the proposed improvements to be constructed on the property and their respective impervious surface areas (the runoff from these areas will be treated): - House, garage, front covered porch, steps and landing of basement access and areaway—2,833.44 square feet - Asphalt driveway— 1,808.95 square feet - Front walkway—376.00 square feet The sum of these proposed impervious surfaces is 5,018.39 square feet. To control the runoff from the proposed residence, including the garage, front covered porch, steps and landing at the basement entrance, and areaway, the water will be directed to ten (10)underground CULTEC R-280HD units that will be located in the west side yard. To control the runoff from the proposed asphalt driveway,the water will be directed to an additional eight (8) CULTEC R-280HD units that will be located in the front yard. These two systems have been designed to detain the runoff, from a 25-year,24-hour storm event, from the respective areas and infiltrate the water back into the soils. The remaining areas (grass areas,rear deck, and portion of the front walk—Total Area of 14,891.27 Sq. Ft.) of the lot will be permitted to discharge untreated runoff as per pre-construction conditions. This remaining area was evaluated using a runoff curve number of 63 and a time of concentration of 8.8 minutes. A hydrological analysis of the property in its proposed state revealed a peak net runoff from the site of 0.73 ft3/sec during a 25-year, 24-hour storm event; a decrease of 0.30 ft'/sec from the pre-development condition. 2 PROPOSED ON-SITE TREE REMOVALS: Survey Designation# Tvne Diameter as Measured 4' Above Existing Grade 1 White Pine 24" 2 Blue Spruce 11" 3 Cam erdown Elm 15" 4 Norway Maple 21" 5 Norway Maple 25" 6 Norway Maple 18" 9 Norway Maple 11" 10 Norway Maple 18" 11 Norway Maple 16" 12 Pine 10" 16 White Cedar 22" 17 Ailanthus 12" 18 Norway Maple 19" 19 Wild Cherry 8" PROPOSED FOOTING DRAIN PUMP SYSTEM: Due to the proposed residence having a finished basement slab set at elevation 218.00, conventional gravity discharge footing drains are not feasible as this proposed elevation is below finished grade. To resolve this, the discharge from the footing drains will be directed to a pump chamber containing a duplex system of 1/3 horsepower sump pumps. The water will be pumped up to a precast concrete junction box and directed to a system of two (2) underground CULTEC R-280HD units. The system has been designed to percolate the water back into the soils away from the structure. An emergency overflow has been incorporated into the design of this system by means of a level spreader. 3 • Vincent A.Ma7110703 SITE LOCATION 2l kers,ighYoukcrs,NPhouc(914) ecec .135.42 135.42 ec.1 M 43 s block 1 s tlock 1 s block 1 - tax IM 5.13 Z.,5.12 tax lot 5.11 r4 Er,lenrey lablon n/f neil stern bh 8ary low Vincent A,Macs o,P.E. 63 LOCATION MAP (N.T.S.)
