Regatta View June 27,2016 Page 2 Following are our observations/comments: General: 1. All documents should reference the City's project number PB#16.018. 2. Please submit the original survey for this project, as required in the Site Plan Review Submittal Checklist. Please add a note on the plans and survey that the topography is based on the NGVD 1929 Elevation datum. 3. Please provide the design, type of construction and materials, and exterior dimensions of proposed buildings,as required in the Site Plan Review Submittal Checklist. Water Service Narrative: 4. The Narrative should clearly state what the required fire flow is for these duplex units. The two closest proposed duplexes are located within 10' of one another therefore it appears from the ISO Guidelines as if 1,500 gpm is required. The report indicates that they anticipate 1,500 gpm is available and fire flow tests will be performed. It is suggest that this testing be done prior to approval of the application. Please provide the results of the hydrant flow tests. Site Plans: 5. The Complete Streets Checklist indicates that street lighting will be provided however none is shown on any of the plans. Please clarify and/or show the locations of proposed lights. 6. The Site Plan depicts a vegetated median at the intersection of Dyer Switch Road and references the typical boulevard road section. There is no typical boulevard road section included in the plans, only a typical road cross section on Sheet 8 which does not show the median. Please provide the boulevard road section. 7. Three (3) drywells are labeled on Sheet 4. Three more are shown on the east portion of the site but are not labeled as such. These additional drywells are included in the SWPPP and should be labeled on Sheet 4 with their invert elevations. 8. Infiltration chambers are depicted on Sheet 4 with a reference to see details. There are no infiltration chamber details included with this plan set. Please revise accordingly. 9. Please complete the table of bioretention area elevations on Sheet 5. 10. Proposed easements for the sanitary sewer and water main extensions should be depicted on the plans. 11. Many of the erosion and sediment control details and notes on Sheet 6 are not legible at the scale and line weight chosen. Please revise so that these details and notes are legible. 12. The limits of clearing and grading shown on Sheet 6 (Erosion and Sediment Control Plan) are not consistent with the limits of clearing identified on Sheet 2 (Existing Conditions and Removals Plan). Please revise accordingly and ensure that the area of disturbance used as the basis for the stormwater management design in the SWPPP is accurate.Also please quantify the area of disturbance on the plans. 13. A line shown on Sheet 6 is depicted in the legend on that sheet as "denotes proposed stone check dam". Based on the way this is shown on the erosion and sediment control plan, it appears that this line is intended to denote a temporary swale, possibly with stone check dams. Please update the legend or plan to clarify this. 14. The Typical Road Cross Section on Sheet 8 contains references to the Town of Malta and Town Engineer approval and does not show the relationship of proposed utilities to one another. Please update this to be applicable to this project. It is our understanding that the proposed road is to be maintained by a home owners association and will not be dedicated to the City of Saratoga Springs. The road should be constructed to the City standards. Please revise accordingly. 15. Both water and sewer mains are shown within the pavement limits with biorention areas located along the edge of pavement. Please indicate the locations of electric, CATV, natural gas and communications lines on the plans. 16. Only garage floor elevations are indicated on the site plans. Please indicate the first floor and basement floor elevations for each unit. 17. There are insufficient spot elevations shown on the site plans-please add additional spot elevations to clearly depict how the site will drain. Tim Wales,P.E. Regatta View June 27,2016 Page 3 18. Please indicate where sump pumps and foundation drains will be discharged. 19. The proposed water main is intended to be dedicated to the City and should conform to City standards. Please address the following discrepancies between the water service details presented on Sheet 10 and City standard details: a. Per City standards all hydrants and valves should open right. The "Typical Hydrant Installation" detail (plan view) on Sheet 10 calls for a valve which opens left. b. The "Typical Hydrant Installation" detail (elevation view) on Sheet 10 references Village of Ballston Spa standards. Another detail labeled "Hydrant Installation" on the right side of this sheet is consistent with City of Saratoga Springs standards. Please revise accordingly. c. The curb box, curb stop, and corporation stop models referenced in the "Water Service" detail are not the City's standard models. Please update accordingly. Project Cost Estimate 20. The cost estimate indicates 20 bioretention areas; only 13 are shown on the plans. Please double check all quantities on the cost estimate and update accordingly. Stormwater Pollution Prevention Plan: 21. The stormwater management plan utilizes infiltration through porous pavement, infiltration chambers and drywells.Only results of deep test pit excavations were submitted.The SWPPP indicates that the required infiltration testing will be completed to confirm infiltration rates. Falling head permeability testing must be performed in accordance with the SWMDM,the designs updated as needed,and the SWPPP revised accordingly and resubmitted for review. 22. The stormwater management plan utilizes infiltration through porous pavement for proposed driveways. Please address the following comments pertaining to the requirements of the NYSDEC Stormwater Management Design Manual (SWMDM)for porous pavement practices: a. The SWMDM requires a 25-foot down-gradient setback from structures for porous pavement practices.The site plans indicate that porous pavement is to be utilized for all proposed driveways,which abut the proposed buildings. Please add sufficient spot elevations to assure water drains away from the structures. b. The SWPPP indicates that the site is to be graded such that porous pavement areas do not receive runoff from adjacent areas.The Grading Plan (Sheet 4)does not contain sufficient detail to assure this. Please add sufficient spot elevations to assure that adjacent areas do not drain onto the pavement. c. The SWMDM requires observation wells to be installed within porous pavement practices.The porous pavement detail on Sheet 10 does not include observation wells. Please revise accordingly. 23. The SWPPP indicates that the NYSDEC and NYSOPRHP have been contacted to request a determination as to whether the project will result in the taking of any species listed as endangered or threatened, and whether the project will result in any adverse effects on cultural resources, respectively. If either of these responses are affirmative then this project will not be eligible for coverage under SPDES General Permit GP-0-15-002.The responses of these two agencies should be submitted to the City when available. The SWPPP should not be approved until those documentation of no effect are provided and included as part of the SWPPP. 24. Please answer Question 5 on the Notice of Intent(NO1). 25. Six proposed drywells are modeled in the HydroCAD model for the project.The drywells are shown with inconsistent dimensions and only one detail is provided in the site plans. In addition,the inverts in the HydroCAD model for Drywell 3 do not match those shown on the plan. Please update dimensions and inverts for consistency between the model and plans. 26. The SWPPP indicates that ownership and maintenance of the SWM practices will be by Regatta View LLC. A formal inspection and maintenance agreement,acceptable to the City and in accordance with City Code Chapter 242, must be in place to assure that the practices will be properly operated and maintained in accordance with the long term operation and maintenance plans included in the SWPPP. Please submit an agreement for the City's review.A sample agreement is available in City Code Chapter 242. Tim Wales,P.E. Regatta View June 27,2016 Page 4 27. The City Engineer's office requires that yearly inspection and maintenance reports for post-construction stormwater management facilities be submitted for their files.This requirement should be added to the SWPPP. In order to expedite and simplify the review of revised materials we would appreciate if the next submission be accompanied by a response letter that describes the revised materials and how our comments were/were not integrated.

Items that have been satisfactorily addressed are not repeated. New comments are presented in bold: General: 1. All documents should reference the City's project number PB# 16.018. The City's project number has been added only to the site plans; it should be added to all site plan application documents (i.e., water report, SWPPP, cost estimate, etc.). 2. Please submit the original survey for this project, as required in the Site Plan Review Submittal Checklist. Please add a note on the plans and survey that the topography is based on the NGVD 1929 Elevation datum. An existing conditions plan has been submitted with notation indicating that the topography is based on the 1929 NGVD elevation datum. The original signed and sealed survey has not been submitted and should be provided to the City. 3. Please provide the design, type of construction and materials, and exterior dimensions of proposed buildings, as required in the Site Plan Review Submittal Checklist. In their comment response letter, EDP included a narrative of the proposed building construction type and materials and indicated that a set of "Development Parameters" would be submitted to be approved with the Site Plan. EDP is requested to provide the following to address this comment: a. Updated Architectural Plans and Elevations b. Submit proposed Development Parameters for review. Water Service Narrative: 4. The Narrative should clearly state what the required fire flow is for these duplex units. The two closest proposed duplexes are located within 10' of one another therefore it appears from the ISO Guidelines as if 1,500 gpm is required. The report indicates that they anticipate 1,500 gpm is available and fire flow tests will be performed. It is suggested that this testing be done prior to approval of the application. Please provide the results of the hydrant flow tests. EDP indicated in the comment response letter and updated application materials, that a fire flow exceeding 1,500 gpm is required but they have not conducted any test to verify that the required flows can be met. Please provide. Site Plans: 5. The Complete Streets Checklist indicates that street lighting will be provided however none is shown on any of the plans. Please clarify and/or show the locations of proposed lights. In their comment response letter, EDP indicated that street lighting will be shown on future plan sets.

Regatta View,2nd Submittal November 21,2018 Page 3 and basement floor elevations in their comment response letter and has noted the basement floor elevation differential on the site plans. EDP is requested to note the first-floor elevations for each unit on the site plans to address this comment. Stormwater Pollution Prevention Plan: 23. The SWPPP indicates that the NYSDEC and NYSOPRHP have been contacted to request a determination as to whether the project will result in the taking of any species listed as endangered or threatened, and whether the project will result in any adverse effects on cultural resources, respectively. If either of these responses are affirmative then this project will not be eligible for coverage under SPDES General Permit GP-0-15-002. The responses of these two agencies should be submitted to the City when available. The SWPPP should not be approved until those documentation of no effect are provided and included as part of the SWPPP. EDP indicated in their response letter that "no known endangered species" and "no impact" letters have been received from DEC and OPRHP respectively, but only the letter from OPRHP was included in the SWPPP. Please update the SWPPP to include documentation from DEC as well. 26. The SWPPP indicates that ownership and maintenance of the SWM practices will be by Regatta View LLC. A formal inspection and maintenance agreement, acceptable to the City and in accordance with City Code Chapter 242, must be in place to assure that the practices will be properly operated and maintained in accordance with the long-term operation and maintenance plans included in the SWPPP. Please submit an agreement for the City's review. A sample agreement is available in City Code Chapter 242. EDP indicated in their response letter that ownership and maintenance will be the responsibility of a homeowner's association (HOA) and that HOA documents will be submitted to the City for review. a. Please submit this documentation in order to address this comment. b. Also,the NOI and MS4 SWPPP acceptance Form needs to be updated to reflect the actual name of the Home Owners Associate before the SWPPP can be approved. New comments pertaining to Planning review and Technical review of the updated site plan application materials are listed below: 28.The new"edge of woods line" shown on Sheet 2 is not consistent with the limits of clearing shown on the same sheet; please revise. Also,the clearing limit needs to be updated to reflect the actual limit of construction (i.e. the Stormtech chambers along Regatta View Drive are shown within the limits of trees to remain, the existing sanitary sewer main on the west side of the site is shown to be removed and replaced, etc.) 29.The delineation of easement to the City and Saratoga County Sewer District shown on Sheet 4 are incomplete. a. Please ensure both easements are clearly delineated, bounded, and labeled. b. Please submit proposed legal descriptions for the easements. Tim Wales,P.E. Regatta View,2nd Submittal November 21,2018 Page 4 30.The silt fence shown on Sheet 9 is drawn perpendicular to contours in some locations. In accordance with the NYS Standards and Specifications for Erosion and Sediment Control (SSESC), silt fence shall be installed parallel to contours to prevent channelization of flow. Please revise. 31. Site construction will disturb in excess of five (5) acres. A detailed phasing/sequencing plan showing how disturbance will be limited to less than five (5) acres at a time needs to be included in the set of plans. This phasing/sequencing plan should clearly indicate and quantify the limits of disturbance within each phase/sequence. 32.The following details should be updated for conformance with City standards: a. Detail 1 on Sheet 10 should be revised to indicate a bicycle-friendly grate. b. Detail 3 on Sheet 10 indicates a 12' wide lane while the City standard is for 18' lanes on a collector street. c. Detail 4 on Sheet 10 is not consistent with the City standard tree planting detail. d. Detail 7 on Sheet 10 should be updated to include required dimensions and contrasting color requirements for detectable warning plates. 33.The HydroCAD model includes subcatchments 10S— 14S which drain to practices 12P and 15P. It is apparent that these subcatchments and practices are intended to model building roofs and porous pavement driveways. However, these subcatchments and practices are not shown on the post-construction watershed delineation map. a. The watershed delineation map and HydroCAD model should be revised for consistency so that the design of these practices can be reviewed. b. It's not clear from the plans how much of each roof and how the roof runoff will be directed to the porous pavement for treatment. Please clearly indicate the tributary areas to each surface and how the roof runoff will be discharged onto the surface of the porous pavement. 34.A layout detail for the Stormtech SC-740 practice (similar to Detail 16 on Sheet 11 for the Stormtech MC-3500 practice) should be added to the site plans to indicate the required dimensions for this practice, consistent with what is modeled in the HydroCAD calculations. As requested,we have also completed our review as it relates to the City Planning and public concerns raised in previous meetings,these comments are presented below. 35.The Saratoga Springs Comprehensive Plan (adopted 2015) and Future Land Use Map is supportive of development of this density and type in the project area. The Future Land Use Map indicates that the Project Area is listed as RN-1 Residential Neighborhood One. The Residential Neighborhood-1 and Residential Neighborhood -2 designations are characterized by single family residential uses with moderate density two-family. While a mix of housing types is present,these areas contain basic character of single-family neighborhoods, such as front and rear yards, driveways, and garages. Small, neighborhood-scale commercial uses may currently exist to complement the residential uses.The maximum residential density in the RN-1 district is 3.5 units per acre. The proposed development's residential density is 3.5 units per Tim Wales,P.E. Regatta View,2nd Submittal November 21,2018 Page 5 acre (calculated as 24 units/6.78 acres).The proposed duplexes are in keeping with the intent and densities of the Future Land Use Map. 36.The Complete Streets Policy (2016)The purpose of the Complete Streets Policy is to ensure that new and updated public and private projects are planned, designed, maintained and operated to enable safe, comfortable and convenient travel to the greatest extent possible for users of all abilities including pedestrians, bicyclists, motorists and transit riders. The proposed street through the development would be classified as a "Neighborhood Street." Section 2-8 of the Complete Streets Plan provides classifications of streets ranging from Bronze to Gold. As proposed the street would be classified as Bronze for its lack of pedestrian lighting and a missing sidewalk on one side of the street. To meet Silver level standards the street would need sidewalks on both sides of the street, ADA compliance at all intersections and 5'grass buffers between sidewalk and street.To reach Gold level,the street would require a full network of sidewalks and crossings, sidewalks present throughout driveways,gaps in street trees filled and pedestrian scale lighting fixtures. a. The Planning Board should decide what level is desired for this development, and b. the applicant should revise the plans accordingly. 37.The Complete Streets Policy (2016) on page 2-2 identifies portions of Dyer Switch Road as a deficient area for sidewalks. The policy recommends installing sidewalk along Dyer Switch to the north of the project, but not directly along the project parcel. The proposed project provides sidewalk west from the intersection of Dyer Switch and Dartmouth Drive to Route 9P/Union Ave but does not provide a sidewalk east from the intersection of Dyer Switch and the proposed street towards the sidewalk deficient area called out on page 2-2 of the Complete Streets Policy. a. The Planning Board may want to consider requiring the extension of the proposed sidewalk east from intersection of Dyer Switch and the proposed street to the edge of adjacent parcel at 12 Dyer Switch Road in order to close gaps in the sidewalk network, and b. the applicant should revise the plans accordingly. 38. Saratoga Greenbelt Connector (adopted 2014) is a plan connecting existing multi-use paths into a 24-mile figure-eight loop around and through the city that can be used by cyclists, runners and pedestrians for both transportation and recreation. The plan indicates that Route 9P/Union Ave (page 1-6) on the western side of the project parcel) is designated as a "Greenbelt Trail Connector" Sheet#3 of 10 from the prior development plans dated 5/19/2016 show an 8' wide pedestrian and bike trail along Route 9P/ Union Ave. The most recent drawing set dated 11/02/2018 do not show the connector trail. a. The Planning Board may want to consider requiring the installation of the greenbelt trail along Route 9P/Union Ave as previously proposed. b. The Planning Board should also consider extending the proposed sidewalk along Dyer Switch Road in order to connect to the new/future Greenbelt Trail, and c. the applicant should revise the plans accordingly. Tim Wales,P.E. Regatta View,2nd Submittal November 21,2018 Page 6 39. Urban and Community Forest Master Plan (2013) The "Urban and Community Forest Master Plan" emphasizes the maintenance of existing trees and the establishment of new street trees. a. Meeting minutes from January 18, 2018 meeting indicate questions about screening from Dyer Switch and Regatta View.The approved 1991 Concept shows a different site layout with larger buffers and relatively smaller area of disturbance. The new drawing shows smaller buffers between Flying Dutchman lots 1 & 2 and the southern portion of the proposed street.The Planning Board may want to consider requiring a clearing restriction easement along Route 9P as an assurance for the screening/visual impact buffer. 40. City of Saratoga Springs Open Space Plan (1994 and 2002) in Appendix A"Open Space and Recreation Resources Map" (page 26) indicates Route 9P/Union Ave along the western edge of the project parcel as part of the "proposed bike trail system." As noted previously Sheet#3 of 10 from the preliminary plans dated 5/19/2016 show an 8' wide pedestrian and bike trail along Route 9P/ Union Ave. The most recent drawing set dated 11/02/2018 do not show the connector trail. a. The Planning Board may want to consider requiring the installation of the greenbelt trail along Route 9P/Union Ave as previously proposed. b. The Planning Board should also consider extending the proposed sidewalk along Dyer Switch Road in order to connect to the new/future Greenbelt Trail, and c. the applicant should revise the plans accordingly.

Please submit proposed legal descriptions for the easements. The applicant has updated the easement boundaries on the plans and indicated that proposed legal descriptions will be submitted with the final plans. 33. The HydroCAD model includes subcatchments 10S— 14S which drain to practices 12P and 15P. It is apparent that these subcatchments and practices are intended to model building roofs and porous pavement driveways. However, these subcatchments and practices are not shown on the post-construction watershed delineation map. a. The watershed delineation map and HydroCAD model should be revised for consistency so that the design of these practices can be reviewed. The updated HydroCAD models were not provided with the updated application materials. Please provide. The following new comments are noted pertaining to the updated watershed delineation map: 1. The updated watershed delineation map is still inconsistent with the previously submitted HydroCAD model. Please revise. 2. The updated watershed delineation map is unclear in its delineation of Subcatchment 55, which includes a portion of the roof buildings and also appears Tim Wales, P.E. Regatta View, 3rd Submittal February 8, 2019 Page 3 of 6 to include a portion of the rear of each lot. Please clarify the bounds of 55, consistent with the grading plan. 3. A typical lot detail has been added to the watershed delineation map which depicts an unidentified feature in the rear of each lot. Please clarify. 4. The location of the two underground infiltration practices shown on the updated watershed delineation map is not consistent with the site plans. Please revise. b. It's not clear from the plans how much of each roof and how the roof runoff will be directed to the porous pavement for treatment. Please clearly indicate the tributary areas to each surface and how the roof runoff will be discharged onto the surface of the porous pavement. A typical lot layout has been added to the watershed delineation map to clarify intended drainage pattern. Please indicate the proposed means of directing runoff to the porous pavement as requested. 34. A layout detail for the Stormtech SC-740 practice (similar to Detail 16 on Sheet 11 for the Stormtech MC-3500 practice) should be added to the site plans to indicate the required dimensions for this practice, consistent with what is modeled in the HydroCAD calculations. A layout detail for the SC-740 practice has been added to the plan but its dimensions are not consistent with the previously submitted HydroCAD calculations. Please revise. As requested, we have also completed our review as it relates to the City Planning and public concerns raised in previous meetings,these comments are presented below. 35.

To reach Gold level, the street would require a full network of sidewalks and crossings, sidewalks present throughout driveways, gaps in street trees filled and pedestrian scale lighting fixtures. a. The Planning Board should decide what level is desired for this development, and b. the applicant should revise the plans accordingly. EDP noted that the project will include street lighting and the sidewalks have been designed consistent with the surrounding neighborhoods. The Planning Board should consider whether neighborhood precedence outweighs adopted community plans. 36. The Complete Streets Policy (2016) on page 2-2 identifies portions of Dyer Switch Road as a deficient area for sidewalks. The policy recommends installing sidewalk along Dyer Switch to the north of the project, but not directly along the project parcel. The proposed project Tim Wales, P.E. Regatta View, 3rd Submittal February 8, 2019 Page 4 of 6 provides sidewalk west from the intersection of Dyer Switch and Dartmouth Drive to Route 9P/Union Ave but does not provide a sidewalk east from the intersection of Dyer Switch and the proposed street towards the sidewalk deficient area called out on page 2-2 of the Complete Streets Policy. a. The Planning Board may want to consider requiring the extension of the proposed sidewalk east from intersection of Dyer Switch and the proposed street to the edge of adjacent parcel at 12 Dyer Switch Road in order to close gaps in the sidewalk network, and b. the applicant should revise the plans accordingly. EDP response is that sidewalk construction as this point is unnecessary because there is currently no sidewalk to connect to. It is recommended that that applicant either build the sidewalk along Dyer Switch Road or post a bond for the eventual construction of this sidewalk. 37. Saratoga Greenbelt Connector (adopted 2014) is a plan connecting existing multi-use paths into a 24-mile figure-eight loop around and through the city that can be used by cyclists, runners and pedestrians for both transportation and recreation. The plan indicates that Route 9P/Union Ave (page 1-6) on the western side of the project parcel) is designated as a "Greenbelt Trail Connector" Sheet#3 of 10 from the prior development plans dated 5/19/2016 show an 8' wide pedestrian and bike trail along Route 9P/ Union Ave. The most recent drawing set dated 11/02/2018 do not show the connector trail. a. The Planning Board may want to consider requiring the installation of the greenbelt trail along Route 9P/Union Ave as previously proposed. b. The Planning Board should also consider extending the proposed sidewalk along Dyer Switch Road in order to connect to the new/future Greenbelt Trail, and c. the applicant should revise the plans accordingly. EDP response is to include a seasonal 5 ft pedestrian pathway located on HOA lands from Dyer Switch Road to Regatta View Drive. The applicant will site the pedestrian pathway to avoid existing vegetation wherever possible; however,there will be some loss of vegetation in this area. The Applicant does not provide details for this path. Will the path be asphalt, gravel, or mulch and will it be maintained and lit? Please provide the required details. 38. City of Saratoga Springs Open Space Plan (1994 and 2002) in Appendix A "Open Space and Recreation Resources Map" (page 26) indicates Route 9P/Union Ave along the western edge of the project parcel as part of the "proposed bike trail system." As noted previously Sheet#3 of 10 from the preliminary plans dated 5/19/2016 show an 8' wide pedestrian and bike trail along Route 9P/ Union Ave. The most recent drawing set dated 11/02/2018 do not show the connector trail. a. The Planning Board may want to consider requiring the installation of the greenbelt trail along Route 9P/Union Ave as previously proposed. Tim Wales, P.E. Regatta View, 3rd Submittal February 8, 2019 Page 6 of 6 drawings indicate that this land has been set aside. Applicants have the option to provide Class B type useable land if the City offers to accept it. If the City does not request 10% Class A or B type useable land the applicant may be required to pay a fee per lot. The proposed subdivision shows no recreational land set asides. Is the proposed subdivision part of an existing HOA and if so, will residents have access to adequate recreational facilities? The applicant should either set aside the required amount of recreation land or clarify how whether or not the subdivision is to be part of an existing HOA that will be providing adequate recreational facilities for residents. 41. The 2nd submittal drawings revision date was November 2, 2018, as was the 3rd submittal revision date — please make sure that all subsequent submittal have a new revision date. 42. Please add a detail of the proposed 5' wide seasonal pedestrian path. 43. This phase of the Interlaken PUD has been revised in concept from a cluster development to a 24 -lot subdivision. Please identify which dimensional requirements set forth in the Interlaken PUD were used for this design. Please add and clearly label the required setbacks on the plans. In order to expedite and simplify the review of revised materials we would appreciate if the next submission be accompanied by a response letter that describes the revised materials and how our comments were/were not integrated.
