The following are responses to the comments. Update plans and documents will be provided at a later date. General: Comment 1: The City's project number of 20200083 should be added to all site plan application and all supporting documents. Response 1: The plans have been updated to include the city project number on each sheet. Comment 2: A Site Plan Application Checklist, Complete Streets Checklist, Environmental Assessment Form and Water Service Connection Agreement were not submitted with this application. If the City would like us to review these documents, please forward to us. Response 2: The Complete Street Checklist, EAF, and Water Service Connection Agreement were previously submitted as part of the Special Use Permit and SEQRA approval. These items as well as the Site Plan Checklist have been included with this comment response letter. Water/Sewer Engineering Report: Comment 3: The report should include a discussion regarding the system, capacity and adequacy of the downstream collection, conveyance and treatment systems (up to and including the wastewater treatment plant) to handle the increase in flow resulting from this project. Please revise accordingly and provide an ability to serve letter form the WWTP operator. Response 3: In discussions with the Saratoga County Sewer District No. 1 they see no issues with the ability to serve this project. A letter will be obtained from the sewer district stating such. Also note that the wastewater flows stated in the Engineers Report do not account for existing flows from the site, therefore the increase in flow from this project to the sewer system is overstated in the Engineers Report. Comment 4: Section IV of the Engineer's Report provides projected wastewater flow rates for two uses only, Sleeping Units and Employees. The Engineer's Report states that there is a proposed bar/lounge included within the hotel but does not include the wastewater generated by this use. There does not appear to be any details on if there will be any food service, and as such full review of the wastewater flow rates cannot be conducted until all potential wastewater uses are fully understood. The Applicant needs to include a discussion on all proposed sewer system components (i.e. grease traps, etc.). Response 4: The proposed bar/lounge will have a total of 55 seats. An additional flow of 1,100 gallons per day(20 gpd per seat- NYSDEC) has been included in Engineering Report calculations. An internal grease trap will be provided, and a note on the plans has been added to sheet L-4.0, sanitary sewer notes, note 6. Comment 5: The hydrants tested do not appear to be the closest hydrants to the site as there appears to be an existing hydrant located immediately adjacent to the proposed hotel. Further these hydrants were tested on March 27, 2018. It is recommended that new hydrant tests be performed on the hydrant located adjacent to the site and because the tests are over 2-years old. Typically, hydrant flow testing shall be no older than six(6) months unless it has been deemed that no changes to the supply or transmission of water within that area have occurred since the test was performed. Our office does not take exception to hydrant flow tests being conducted in support of building permit application, so long at the City does not take exception. The fire code official shall be notified prior to the water supply test. Further, our office understands that a full review of the sprinkler system and NFF will occur during the building permit application. Response 5: There have been no significant changes to the supply or transmission of water in this area since the test. As noted, the previous test was completed in close proximity, +/- 400' away. Project Cost Estimate: Comment 6: It appears the unit prices used in the provided cost estimate may be below what is typically seen for site work within the NYSDOT ROW. Please review and update as necessary. Response 6: Unit prices have been updated. Site Plans: Comment 7: Please provide a signed and sealed copy of the boundary, topographic and utility survey prepared by CHA Consulting. Response 7: A signed and sealed copy of the survey will be provided with the final accepted set of plans for signature. Comment 8: Sheet L-5.1 titled "Lighting Plan" is missing from the site drawings. Please provide in subsequent submissions. A review of the lighting plan will occur once provided. Response 8: The lighting plan has been included in the site plans for review. Comment 9: Please provide additional spot elevations throughout the site and particularly at all handicap parking spaces to assure the slopes do not exceed the required minimum. Response 9: Spot grades will be added throughout the site and specifically at the handicap parking spaces to verify the slopes for ADA compliance. All handicap parking spaces will meet ADA requirements with regards to slope. Comment 10: There appears to be proposed work within the NYSDOT ROW, including an open cut trench through the road. The Applicant to provide the plans to the NYSDOT for review and comment. Response 10: Per discussion with the NYSDOT, this portion of South Broadway is within the city limits and the city is responsible for the maintenance and permitting. Therefore the NYSDOT does not have jurisdiction. Comment 11: It appears, based on the location of the construction entrance, that construction traffic will be directed to use Todd Street to enter and exit the site. It appears that only a portion of Todd Street is to be repaved following construction. The City should consider requiring the Applicant to re-pave the full width of Todd Street since it will be significantly affected by construction traffic? Response 11: No response required, comment to the city. City to advise. Comment 12: Further, the Todd Street intersection with South Broadway appears to have a small turning radius. It is assumed that concrete trucks will use Todd Street (based on the location of the construction entrance). Please submit vehicular maneuvering plans showing construction vehicles can be accommodated at this entrance. Response 12: The turning radius for Todd Street is existing and is to the standard of the city and is located entirely within their ROW. The Todd Street width is increasing but the radius of the curb cut will remain the same as the existing condition. Comment 13: It is unclear what the proposed width of Todd Street will be following construction; please revise the plans accordingly. Response 13: The Todd Street width dimensions have been added to the plans. Comment 14: The Applicant shall provide the plans and engineering report to the Fire Department for review and comment. Please submit for the record a letter from the Fire Department indicating that they can adequately service the proposed use. Response 14: It is our understanding that the planning department sends the submission drawings along to the fire department for their review and comment. They have in the past reviewed drawings and provided comments. Comment 15: Please provide a fire truck maneuvering plan, using the largest responding emergency vehicle as prescribed by the responding fire department, showing access through the site. Section D105.1 of the 2015 Fire Code states "Where the vertical distance between the grade plane and the highest roof surface exceeds 30 feet (9144 mm), approved aerial fire apparatus access roads shall be provided. For purposes of this section, the highest roof surface shall be determined by measurement to the eave of a pitched roof, the intersection of the roof to the exterior wall, or the top of parapet walls, whichever is greater." Section D105.2 of the 2015 Fire Code states "Aerial fire apparatus access roads shall have a minimum unobstructed width of 26 feet (7925 mm), exclusive of shoulders, in the immediate vicinity of the building or portion thereof." The cover sheet indicates the building will be 4-stories and 49 feet high. The side of the building on which the aerial fire apparatus access road is positioned shall be approved by the fire code official. The Applicant to provide which side of the building once determined by the fire code official. Conformance to the Fire Code will be reviewed once an answer is provided Response 15: It is our understanding that fire truck access thru the site is not required as the building can be accessed from city ROW's along two sides. This is how the other properties within this corridor accommodate aerial fire apparatus access, The front fa�ade of the building is approximately 2 feet from the curb on South Broadway. This is within the requirements for the aerial access road standards within section d of the fire code. Access to the rear of the site can be accommodated but not as a fire apparatus access road. Comment 16: The Applicant to provide the gross building area of the proposed building. Response 16: The building Gross floor area has been added to the cover sheet. Comment 17: The layout of the proposed parking within the building is not depicted. Please provide. Response 17: Architectural layout of the interior parking garage has been added to sheet L-2.1. Comment 18: Please revise the design to include gas and electric utilities that are to service the proposed structures. Drawings should reflect the location of utility lines, points of connection and the location of ineters, transformers, etc. along with landscape screening. Response 18: The gas and electric utility design locations have been added to the plans as well as the location for the gas meter and transformer within the site plan development area. Comment 19: Detail 5 Sheet L-6.4 does not conform to the City of Saratoga Springs standard details. The specified pipe zone backfill should be "well graded sand with 3/-inch maximum particle size and not more than 10% passing #200 sieve...". The plans indicate NYSDOT Size 1 &2 crushed aggregate for pipe zone backfill which has a larger gradation than the City standard. Please revise and cross reference all details to ensure conformance with City standards. Response 19: The proposed detail has been historically used for projects in the City with no issues. Proposed gradation has 90-100% passing the 1" sieve with less than 1% passing the #200 sieve and is in close conformance with the City standards. Comment 20: It appears that there will be a permanent shared access and parking with both the neighboring parcels located at the southeast corner of the Lincoln Avenue and S. Broadway intersection. Please submit a copy of the agreements with these two parcel owners for the City's records— please note that these agreements will need to be filed in the County Clerk's office for all properties involved. Also please depict the limits of the proposed easement on the plans. Further, since access to those existing two parcels is being altered the Applicant shall re-evaluate fire apparatus access and turning maneuverability for those parcels as well. Please submit appropriate maneuverability plans. Response 20: A shared access and parking agreement is proposed and will be provided to the city for their records as well as being filed with the county clerk's office. Fire apparatus access should not change for those properties as they have frontage along the city ROW on Lincoln and South Broadway which is the anticipated apparatus access point. Comment 21: The existing hydrant on South Broadway appears to be connected to an abandoned watermain according to the utility plan sheet. Further, it does not appear that the utility plan depicts any other new or existing hydrants. The Applicant to clarify or revise accordingly. Response 21: Based on discussions w/the city,the existing hydrant is connect to the 12" main on the west side of South Broadway. The utility plan has been updated accordingly. Ne new hydrants are proposed as part of this project. Comment 22: Sheet L-2.0 depicts a retaining wall that runs adjacent to the parking structure ramp. It is anticipated that sheeting will be required in order to facilitate construction of the building and the retaining walls or an easement will be required from the adjoining property owner. Please note as such on plans or show the proposed limits of the temporary construction easement and provide a copy of the agreement with the neighboring property owner for the City's record. Response 22: The plans have been revised to show the limits of construction and note added to sheet L-2.0. It is assumed sheeting will be required to facilitate construction. Comment 23: Sheet L-3.0 depicts a trench drain that is noted as being internally drained as is catch basin 7. No MEP plans or structure details were provided with this submission. Where does this system discharge? How is it treated? It is lower than the surrounding storm sewer system? Please clarify and revise design accordingly. Response 23: The trench drain will enter the drainage system within the interior parking garage where it will be pumped to the storm pipe connected to the catch basin in South Broadway. Since this project is redevelopment this portion of stormwater is not being treated. SWPPP: Comment 24: The project is a re-development with an increase in impervious area. The pre-development watershed map does not show sufficient existing conditions to verify the on- and off-site watershed delineation nor their impervious surfaces. Please updated the SWPPP accordingly. Response 24: Edge of pavement has been darkened on the Existing Conditions Watershed Map to more clearly delineate impervious surfaces. Comment 25: The existing conditions subcatchment 1 lists 39,120 sq./ft. of Paved parking as the only impervious surface, however it appears that the existing buildings, Todd Street, gazebos etc. are not accounted for. Please clarify and revise the SWPPP accordingly. Response 25: All impervious areas are accounted for and are included under the "paved parking" area calculation. All impervious areas have a CN number of 98, regardless if it is a building or parking lot. Comment 26: It appears that AP-1 is the existing catch basin at the south corner of Todd Street. The SWPPP must clearly describe the exact design point into which stormwater is directed. Please revise all design points accordingly. We believe that AP-1 should be broken up into two design points —the catch basin located at the south corner of Todd Street and the catch basin located just upstream of it, since the pipe between the two catch basins could be overwhelmed by proposed storm system. Response 26: AP-1 represents runoff entering the existing catch basin in South Broadway, north of Todd Street. The catch basin at the south end of Todd Street does not see any flow from the project site. Language in the SWPPP has been updated to specify location of AP-1. Comment 27: There is insufficient topographical information to review the pre-and post-subcatchment boundaries that flow onto the site from neighboring properties. Based on the topographic information provided, the neighboring properties to the north, east and south side of Todd Street do flow onto the site and will be collected and conveyed into the proposed stormwater management systems, thereby rendering them inadequate. Please revise the plans, and SWPPP accordingly. Response 27: The property to the east of Todd Street do not discharge stormwater runoff onto the site. Stormwater runoff from properties along Gurtler Lane travels north to Lincoln Avenue. Additionally, not shown on the survey is a large berm along the existing fence line that prohibits stormwater runoff from Gurtler Lane to discharge on the project site. All stormwater runoff from these neighboring properties travels north along the east side of Gurtler Lane as evidenced by the pavement erosion at neighboring property lines. Stormwater runoff from properties to the south of Todd Street travels southwest along Todd Street and eventually onto South Broadway. The SWPPP has been updated to remove the portion of Gurtler Lane that does not contribute stormwater runoff to the proposed stormwater management system. Comment 28: The post-development model indicates that subcatchments 1, 3, 11 and 12 (which include the majority of the roofl are tributary to AP-1. It is unclear how those subcatchments get treated prior to discharge to AP-1. Please clarify and revise both the plans and the SWPPP accordingly. Response 28: The projects entire treated WQv is provided by the underground chambers. Since this project is classified as redevelopment 100% of all new impervious area and 25% of existing disturbed area needs to be treated. Subcatchment 1, 3, 11, and 12 are not required to be treated due to the redevelopment requirements. Comment 29: It is not clear where the roof(subcatchment 11 and 12) nor the internally drained trench drain and CB noted previously are to be discharged. Please clarify and revise both the plans and the SWPPP accordingly. Response 29: A note has been added to sheet L-3.0 indicating the roof drain connection. Runoff collected in the trench drain and garage CB will discharge to this same line. Comment 30: The stormwater management report indicates that an isolator row in the underground chambers will provide the required pre-treatment. The HydroCAD model indicates however that exfiltration is utilized for all 52 of the chambers, which indicates exfiltration is utilized in the pre-treatment area. According to discussions with NYSDEC representatives, exfiltration may not be modeled in pre-treatment facilities. Please revise the SWPPP accordingly. Response 30: The exfiltration modeled in the system is consistent with the overall area of the stone subbase below the chambers. The exfiltration for all 52 chambers has been maintained. The isolator row being wrapped in fabric does not affect the ability of the stone subbase below these chambers to infiltrate at the field tested rate. Comment 31: Please provide pre-treatment calculations for the isolator row that indicates it meets the requirements of the NYS Stormwater Management Design Manual (SMDM). Response 31: The peak flow to the proposed underground infiltration chambers during the 90% rainfall event is 1.12 cfs that is to be pretreated by three SC-740 chambers. The SC-740 have a water quality treatment rate of 0.033 cfs/sf. Each chamber has a total of 30.42 sf and therefore are capable of treating 3.01 cfs. The three pretreatment chambers provide 100% pretreatment of the water quality volume per the NYS Stormwater Management Design Manual (SMDM). Comment 32: All of the structures in the stormwater treatment system need to be modeled, specifically the diversion structure and outlet control structure. Please revise the SWPPP accordingly. Response 32: The outlet control is modeled in SMP1. The diversion manhole has been added to the HydroCAD model. Comment 33: It is unclear how all portions of subcatchment 10 will discharge to catch basin 3. Please clarify and revise the SWPPP accordingly. Response 33: SWPPP has been revised to depict subcatchment 10 discharging to CB2, which subsequently discharges to catch basin 3. Subcatchment 10 and subcatchment 9 discharge to CB-2 via the roof drain located along the east side of the building. Comment 34: It is unclear how all portions of subcatchment 9 will discharge to catch basin 2. Please clarify and revise the SWPPP accordingly. Response 34: See response 33. Comment 35: The plans do not show how the trench drain and catch basin 7 are connected to the internal system noted on the plans — please indicate piping for these components. Response 35: Trench drain and CB-7 are internally connected and discharge to the existing catch basin in South Broadway. Piping inside the building footprint will be designed by the MEP engineer. MEP plans will be provided to the building department for review during the building permit review. Comment 36: In the HydroCAD model, the runoff depth shows a ">" indicating that a time span of 5-20 hours is not sufficient to realize the full effects of the storm. The applicant to revise the time span such that it is at least the length of the storm analyzed (24 hours). Response 36: The time span has been increased to 24 hours. Note that there is no change to peak flow rates due to this change. Comment 37: Compaction of the soil within the future location of the underground infiltration chambers may occur due to construction traffic. Please add a note to the plans indicating that construction traffic must avoid the area of the infiltration system to avoid over compacting and adversely affecting the natural infiltration rate of the soil. Response 37: A note has been added to Sheet L-1.0. Comment 38: Falling head permeability tests must be conducted within the limits of the proposed underground infiltration chambers in accordance with the NYS Stormwater Management Design Manual (SMDM). Please add the locations of the infiltration tests, borings, etc. along with the results of these tests on the site plans so that we can confirm this criterion is met. Response 38: Location of infiltration tests and the associated test results have been added to the plans. Infiltration tests I-2 and I-3 are located on either ends of the proposed underground chambers. Additional test pits were completed in the area of the proposed infiltration chambers, test pit locations and test results have been added to the plans. Comment 39: The infiltration tests conducted were performed 4' below existing site grades (approximately elevation of 313') at a rate of 34-36 in/hour. The SMDM requires that the infiltration testing be performed 24" below the bottom of the proposed infiltration system. The testing presented is not. It is actually 5 feet above the required testing elevation of 308'. Please conduct testing that meets this requirement, verify that the design rate is appropriate and revise the plans and SWPPP accordingly. Response 39: Additional permeability tests were conducted at the required depth. The test pits found large granular sand with infiltration rates greater than 120 in/hr. The chambers will continue to be modeled at the previous infiltration rate of 34 in/hour for a factor of safety. Comment 40: Section 4.1 of the SWPPP notes: "Seed and mulch bare soil areas within 14 days of disturbance unless construction will resume in that area within 21 days". However, the SPDES General Permit requires that stabilization be initialized in such areas by the end of the next business day and be complete within 14 days. Please revise the note accordingly. Response 40: Note has been revised accordingly. Comment 41: City Code Chapter 242 requires long-term maintenance of the stormwater management practices. The following notes need to be added to each SWPPP under Post-Construction Operation and Maintenance of Stormwater Control Devices: a. "All post-construction stormwater management facilities must be inspected annually by a qualified professional, a report prepared and submitted to the City Engineer documenting the inspections as well as the maintenance activities that were completed during the prior year." b. "The City of Saratoga Springs shall approve a formal maintenance and inspection agreement in accordance with City Code Chapter 242 for stormwater management facilities to ensure the practices will be properly operated and maintained in accordance with the long-term operation and maintenance plans. This agreement shall be binding on all subsequent landowners and recorded in the office of the County Clerk as a deed restriction on the property."A draft maintenance agreement was provided and shall be reviewed by the City and City's counsel. Response 41: Notes regarding inspections are included in the SWPPP on page 10 under"Post Construction Stormwater Maintenance." A draft maintenance agreement will be provided to the City for review and approval. Sincerely, Douglas B.

Overview This Stormwater Pollution Prevention Plan (SWPPP) is prepared to inform the landowner and construction personnel of the measures to be implemented for controlling runoff and pollutants from the site during and after construction activities. The objective of this plan is to comply with the New York Department of Environmental Conservation (NYSDEC) State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Construction Activities, Permit No. GP- 0-20-001 requirements. Any material conflicts between this plan and the site plans, specification or instructions, must be brought to the attention of the design professional. The project may have other permits and it is the responsibility of the owner and contractor to know and understand all permits. The operator will be issued a bill from New York State for a one hundred and ten dollar ($110.00) annual fee for the open GP-0-20-001 permit. The operator will also be billed by New York State for a one time one hundred and ten dollar ($110.00) per acre fee for the proposed disturbed soil area listed in the NOI, and finally a one time six hundred and seventy five ($675.00) per acre fee for the proposed increased impervious area listed in the NOI. The operator is responsible to maintain onsite in a secure location that is accessible during normal working hours to an individual performing a compliance inspection, the following information: ✓ the Notice of Intent (NOI), ✓ the NYS Department of Environmental Conservation NOI Acknowledgement Letter, ✓ the SWPPP, ✓ a copy of the General Permit (included in the SWPPP), ✓ MS4 SWPPP Acceptance Form (where applicable), and ✓ All inspection reports. All post-construction stormwater management facilities must be inspected annually by a qualified professional, a report prepared and submitted to the City Engineer documenting the inspections as well as the maintenance activities that were completed during the prior year. Technical standards are detailed in the "New York State Standards and Specifications for Sediment and Erosion and Sediment Control (November 2016)", as well as illustrated on the Construction Drawings included in Appendix C. The design of post- construction stormwater control practices follow the guidance provided by "New York State Stormwater Management Design Manual." � The �P+ �I�DUP Page 1 Stormwater Pollution Prevention Plan 176 South Broadway The LA Group Project # 2016144 2.0 SWPPP REVIEW, UPDATE 2.1 SWPPP Review Applicable Federal, State, and local regulatory agencies that have jurisdiction may elect to review this SWPPP and notify the permittee in writing that the SWPPP does not meet the requirements of their regulations. If the SWPPP needs to be revised, the permittee and the site contractor will make the required modifications within seven days of such notification and submit written certification to the notifying agency that the changes have been implemented. A copy of the SWPPP will be kept available on site for review by regulatory agencies, engineers, and subcontractors. This Project is in the City of Saratoga Springs which is a regulated MS4 Community, so a copy of this SWPPP was sent to the City for review. A copy of the signed MS4 Acceptance form is provided in Appendix A of this SWPPP. 2.2 SWPPP Update The permittee identified in this SWPPP shall amend the SWPPP under the following conditions: ✓ Whenever the current provisions prove to be ineffective in minimizing pollutants in stormwater discharge from the site ✓ Whenever there is a change in design, construction or operation that could have an effect on the discharge of pollutants ✓ To address issues or deficiencies identified during an inspection by the qualified inspector, the Department or other regulatory authority ✓ To identify a new subcontractor that will implement any part of the SWPPP. If modifications are required to the post-stormwater management practices and the Project is within a regulated, traditional land use control MS4, the owner or operator of the Project must notify the MS4 in writing of any planned amendments or modifications to the post-construction stormwater management practice component of the SWPPP. Unless otherwise notified by the MS4, the owner or operator shall have the SWPPP amendments or modifications reviewed and accepted by the MS4 prior to commencing construction of the post-construction stormwater management practice. The SWPPP PLAN CHANGES, AUTHORIZATION, AND CHANGE CERTIFICATION form (Appendix E) must be filled out and a copy retained onsite during construction. If modifications are required to the post-stormwater management practices and the Project is not within a Regulated, Traditional Land Use Control MS4, the changes shall be documented in the SWPPP kept onsite. � The �P+ �I�DUP Page 2 Stormwater Pollution Prevention Plan 176 South Broadway The LA Group Project # 2016144 3.0 SITE ASSESSMENT, EVALUATION AND PLANNING 3.1 Project Location The Project is located on South Broadway (NYS Route 29), approximately 250 feet south of the intersection South Broadway and Lincoln Avenue, City of Saratoga Springs, Saratoga County, NY 12866. Access to the site is off both South Broadway and Lincoln Avenue. See Appendix C for a general site location map. 3.2 Pre-Development Conditions Currently, the site abuts a strip mall to the south and commercial parcels to the North. The site is bound to the west by South Broadway and residential parcels to the east. The existing cover present in the proposed area of disturbance is an existing motel and wooded area. 3.3 Project Type This project is a mixture of new development and redevelopment and has been designed in accordance with Chapter 4 and Chapter 9 of the NYSDEC Stormwater Management Design Manual and NYSDEC's General Permit (GP-0-20-001) for construction activities. 3.4 Project Scope The Project includes the construction of a four (4) story hotel. The remainder of the proposed site improvements includes construction of a parking lot, site lighting, landscaping, stormwater controls, and connections to the municipal water and sewer. The Project Site represents the area that will be disturbed as a result of the Project. 3.5 Historic Preservation Determination/Endangered Species The project area is within an area that is shown on the OPRHP website that might possibly contain archeologically sensitive resources and therefore a phase 1A and 1 B archeological study was completed in August of 2016. The results of the study did not identify the presence of archeological sites and that no additional investigation was recommended. The Archeological study and OPRHP no effect letter can be found in Appendix G. The Project in within an area that may contain threatened or endangered species, or a critical habitat. A field survey was completed and it was determined that neither the Karner Blue Butterfly nor the Northern Long Eared Bat habitats were present within the project site.

When washing is required, it shall be done in an area stabilized with aggregate and wash water shall be directed away from streams or wetlands preferably to a broad grassed area or a stormwater pond. ✓ Replace top-soil, mulch and seed where seeding has been disturbed. 4.5 Erosion and Sediment Control Inspection ■ It is recommended that a rain gage be installed at the site. ■ A qualified inspector shall conduct an assessment of the site prior to the commencement of construction and certify in an inspection report that the appropriate erosion and sediment controls described in the SWPPP and required by GP-0-20-001 have been adequately installed to ensure overall preparedness of the site for commencement of construction. ■ This qualified inspector must be a Licensed Professional Engineer, Certified Professional in Erosion and Sediment Control (CPESC), Registered Landscape Architect, or someone working under the direct supervision of, and at the same company as, the licensed Professional Engineer or Registered Landscape Architect, provided they have received 4 hours of Department endorsed training in proper erosion and sediment control principles from a Soil and Water Conservation District, or other Department endorsed entity. After receiving the initial training, the qualified inspector shall receive 4 hours of training every 3 years. ■ The day-to-day erosion control activities on the site will be monitored by the construction manager. The qualified inspector (as defined by the NYS DEC SPDES regulations) and his crews will make at least one inspection every seven (7) days of erosion control devices, and non-stabilized areas during construction. A maintenance inspection report will be completed by the qualified inspector after each inspection. The report form to be completed by the inspector is attached in Appendix D. Reports should be compiled and maintained on-site in the SWPPP 3-ring binder. ■ All measures will be maintained in good working order; if repair is necessary, it will be initiated within 24 hours of report. The qualified inspector shall take photographs of any needed repairs and also � The �P+ �I�DUP Page 6 Stormwater Pollution Prevention Plan 176 South Broadway The LA Group Project # 2016144 photograph when the repairs are completed. These photographs will be time and date stamped and attached to the weekly inspection report. ■ Seeded and planted areas will be inspected for bare spots, washouts, and healthy growth. If necessary, spot reseeding or sodding will be implemented. ■ A trained contractor will be an employee from the contracting company responsible for the implementation of the SWPPP. This person will be onsite when any soil disturbing activities are being conducted. The trained contractor must have received 4 hours of Department endorsed training in proper erosion and sediment control principles from a Soil and Water Conservation District, or other Department endorsed entity. After receiving the initial training, the qualified inspector shall receive 4 hours of training every 3 years.

Post-construction maintenance for this project will consist of regular inspections of permanent stormwater management facilities and steep slopes. These maintenance procedures are essential to assure continual performance of the stormwater management practices on your site. During the inspection and any maintenance activity to the stormwater management practices, the responsible party should fill out an inspection and maintenance log (Appendix E) to record that it was done. Annual inspections of the post construction stormwater management practices shall be completed and inspection reports shall be sent to the office of the City Engineer for their records. The City of Saratoga Springs shall approve a formal maintenance and inspection agreement in accordance with City Code Chapter 242 for stormwater management facilities to ensure the practices will be properly operated and maintained in accordance with the long term operation and maintenance plans. This agreement shall be binding on all subsequent land owners and recorded in the office of the County Clerk as a deed restriction on the property. Catch Basins (All) ■ Sediment removal with a vacuum truck should be done at least once a year, preferably after spring runoff and then in early fall, or when they are at 50% capacity, whichever comes first. ■ Any mechanical valves should be operated for inspection every two months. Underground Infiltration Chambers ■ The systems should be inspected quarterly for the first year and if there are no problems, the system can be inspected annually after the first year. ■ If sediment is accumulating on the bottom of the system, pump in water via a flushing port or observation well and then pump the sediment laden water out via the flushing port or the inlet. This can be done with a vacuum truck. The system may have to be flushed multiple times until it is clean of sediment. ■ Also, the manifold feeding the pipe storage should be flushed by pumping water in the manhole access and out the flushing port. This should be done during the routine inspection. � The �P+ �I�DUP Page 10 Stormwater Pollution Prevention Plan 176 South Broadway The LA Group Project # 2016144 7.0 CONSTRUCTION WASTE Waste Materials: All waste materials generated during construction will be disposed at a suitable landfill, or transfer station. Hazardous Waste: The project will not be a generator of hazardous waste and it is not anticipated that any hazardous waste will be generated during construction. If there are any materials generated, a licensed hazardous waste carrier will be contracted to dispose the hazardous material at a suitable disposal site. If hazardous materials are discovered during construction, the work will be stopped until the issue is resolved. Waste: Portable sanitary facilities will be made available to construction personnel and will be serviced regularly. 8.0 OFFSITE VEHICLE TRACKING Excavation equipment involved with the construction will remain on the project site and will not regularly egress or ingress the site. Any trucks used to bring in materials or remove materials via municipal paved roads will do so over a stabilized construction entrance. If any off-site vehicle tracking occurs, the contractor will be directed to initiate, street sweeping program in the immediate vicinity of the site. 9.0 TEMPORARY STABILIZATION FOR FROZEN CONDITIONS The following temporary stabilization measures MUST be performed when construction is occurring during winter/frozen ground conditions. The following requirements do not supersede any other requirements of this SWPPP as they apply to non-frozen ground conditions. ■ Perimeter erosion control MUST still be installed prior to earthwork disturbance as per this SWPPP. ■ Any areas that cannot be seeded to turf by October 1 or earlier will receive a temporary seeding. The temporary seeding will consist of winter rye seeded at the rate of 120 pounds per acre (2.5 pounds per 1,000 square feet) or stabilized as per the temporary stabilization for winter construction/frozen conditions. ■ Any area of disturbance that will remain inactive for a period of 14 consecutive days MUST be mulched. This includes any previously disturbed areas that are covered with snow. ■ Mulch MUST consist of loose straw applied at the rate of 2 to 3 bales (90 to 100 pounds) per thousand square feet. ■ Mulch MUST be applied uniformly over the area of bare soil or bare soil that is covered with snow. For the latter condition, mulch MUST be applied on top of snow. � The �P+ �I�DUP Page 11 Stormwater Pollution Prevention Plan 176 South Broadway The LA Group Project # 2016144 ■ Using a tracked vehicle, mulch MUST be crimped into the bare soil/snow. The tracked vehicle MUST be driven across the mulched areas in at least two directions to maximize crimping of mulch into the soil/snow. ■ If mulch gets blown off an area to a significant degree, the site inspector WILL require that an area be re-mulched in accordance with Items 2 through 5 above, and this area WILL be included on the inspection checklist for the next inspection. ■ If a particular area repeatedly experiences loss of mulch due to wind, then the inspector WILL require that an alternative method be used to secure the mulch in place. Such alternatives may include the use of netting, tackifier or other methods deemed appropriate by the inspector. ■ During periods when snow is melting and/or surface soils are thawing during daytime hours, mulched areas MUST be re-tracked (crimped) as per Item 5 above at least once every seven days, more frequently if directed by the inspector. Additional mulch may be required to obtain complete coverage of an area. Biodegradable erosion control matting may be required on steeper slopes. ■ Additional stabilization measures for non-frozen ground conditions described in this SWPPP WILL be implemented at the time deemed appropriate by the inspector. During the winter season, if a site has been stabilized and soil disturbing activities have been suspended for the winter, weekly inspections can be suspended. However, monthly inspections must still be conducted. All normal weekly inspections must resume when soil disturbing activities resume. 10.0 SPILL PREVENTION PRACTICES Good Housekeeping and Material Management Practices The following good housekeeping and material management practices will be followed on site during the construction project to reduce the risk of spills or other accidental exposure of materials and substances to stormwater runoff. ■ Materials will be brought on site in the minimum quantities required. ■ All materials stored on site will be stored in a neat, orderly manner in their appropriate containers, and if possible, under a roof or other enclosure. ■ Products will be kept in their original containers with the original manufacturer's label. ■ Substances will not be mixed with one another unless recommended by the manufacturer. ■ Whenever possible, all of a product will be used up before disposal. ■ Manufacturer's recommendations for proper use and disposal will be followed. � The �P+ �I�DUP Page 12 Stormwater Pollution Prevention Plan 176 South Broadway The LA Group Project # 2016144 ■ The construction manager or his designee will inspect regularly to ensure proper use and disposal of materials on site. ■ The contractor shall prohibit washing of tools, equipment, and machinery in or within 100 feet of any watercourse or wetland. ■ All above grade storage tanks are to be protected from vehicle damage by temporary barriers. Inventory for Pollution Prevention Plan The materials and substances listed below are expected to be on-site during construction. ■ Petroleum for fueling vehicles will be stored in above ground storage tanks. Tanks will either be steel with an enclosure capable of holding 110% of the storage tank volume or of a Con-Store, concrete encased type typically employed by NYSDOT. Hydraulic oil and other oils will be stored in their original containers. Concrete and asphalt will be stored in the original delivery trucks. ■ Fertilizer may be stored on site in its original container for a short period of time prior to seeding. Original containers will be safely piled on pallets or similar devices to protect from moisture. ■ Paints and other similar materials will be stored in their original containers and all empty containers will be disposed of in accordance with label directions. ■ Portable sanitary facilities, which contain chemical disinfectants (deodorants) will be located on-site, with the disinfectants held in the tank of the toilet.

Any vehicle leaking fuel or hydraulic fuel will be immediately scheduled for repairs and use will be discontinued until repairs are made. Fertilizers: ■ Fertilizer will be stored in its original containers on pallets with water resistant coverings. ■ Proper delivery scheduling will minimize storage time. ■ Any damaged containers will be repaired immediately upon discovery and any released fertilizer recovered to the fullest extent practicable. Paints: ■ All containers will be tightly sealed and stored when not required for use. ■ Excess paint will not be discharged to the storm water system or wastewater system, but will be properly disposed of according to manufacturers' instructions or State and local regulations. Concrete Trucks: � The �P+ �I�DUP Page 14 Stormwater Pollution Prevention Plan 176 South Broadway The LA Group Project # 2016144 ■ Concrete trucks will be allowed to wash out or discharge surplus concrete or drum wash water only at designated locations on site. Asphalt Trucks: ■ Asphalt trucks shall not discharge surplus asphalt on the site. Spill Control Practices In addition to the good housekeeping and material management practices discussed in the previous sections of this plan, the following practices will be followed for spill prevention and cleanup. The construction manager or site superintendent responsible for the day-to-day site operations will be the spill prevention and cleanup coordinator. He will designate at least three other site personnel who will receive spill prevention and cleanup training. These individuals will each become responsible for a particular phase of prevention and cleanup. The names of responsible spill personnel will be posted in the material storage area and in the onsite construction office or trailer. ■ Manufacturers' recommended methods for spill cleanup will be clearly posted and site personnel will be made aware of the procedures and the location of the information and cleanup supplies. Any spill in excess or suspected to be in excess of two gallons will be reported to the NYSDEC Regional Spill Response Unit. Notification to the NYSDEC (1-800-457-7362) must be completed within two hours of the discovery of the spill. ■ Materials and equipment necessary for spill cleanup will be kept in the material storage area onsite. Equipment and materials will include but not be limited to absorbent pads, brooms, dust pans, mops, rags, gloves, goggles, activated clay, sand, sawdust, and plastic and metal trash containers specifically for this purpose. ■ All spills will be cleaned up immediately after discovery. ■ The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with spilled substance. ■ Spills of toxic or hazardous material will be reported to the appropriate State or local government agency, regardless of the size � The �P+ �I�DUP Page 15 Stormwater Pollution Prevention Plan 176 South Broadway The LA Group Project # 2016144 11 .0 CERTIFICATIONS Preparer Certification of Compliance with Federal, State, and Local Regulations This Stormwater Pollution Prevention Plan was prepared in accordance with the New York State Department of Environmental Conservation SPDES General Permit for Stormwater Discharges from Construction Activities (Permit No. GP-0-20-001), pursuant to Article 17, Titles 7, 8 and Article 70 of the Environmental Conservation Law.

Clearing activities can include, but are not limited to, logging equipment operation, the cutting and skidding of trees, tree removal, stump removal and/or brush removal. Construction activity does not include routine maintenance that is performed to maintain the original line and grade, hydraulic capacity, or original purpose of a facility. Construction Phasing Plan - a plan designed to construct particular portions of an individual project at different times. Phasing is often used when a project is very large to limit the disturbance at a single time to 5 acres per phase. Erosion and Sediment Control Practices —temporary measures installed prior to construction and maintained during construction to temporarily treat any stormwater runoff. Once construction is completed and post-construction stormwater management practices are installed and the site is stabilized, the erosion and sediment control practices are removed from the site. Final Stabilization - means that all soil disturbance activities have ceased and a uniform, perennial vegetative cover with a density of eighty (80) percent over the entire pervious surface has been established; or other equivalent stabilization measures, such as permanent landscape mulches, rock rip-rap or washed/crushed stone have been applied on all disturbed areas that are not covered by permanent structures, concrete pavement. Green Infrastructure — in the context of stormwater management, the term green infrastructure includes a wide array of practices at multiple scales to manage and treat stormwater, maintain and restore natural hydrology and ecological function by infiltration, evapotranspiration, capture and reuse of stormwater, and establishment of natural vegetative features. On a regional scale, green infrastructure is the preservation and restoration of natural landscape features, such as forests, floodplains and wetlands, coupled with policies such as infill and redevelopment that reduce overall imperviousness in a watershed or ecoregion. On the local scale green infrastructure consist of site and neighborhood specific practices and runoff reduction techniques. Such practices essentially result in runoff reduction and or establishment of habitat areas with significant utilization of soils, vegetation, and engineered media rather than traditional hardscape collection, conveyance and storage structures. Some examples include green roofs, trees and tree boxes, pervious pavement, rain gardens, vegetated swales, planters, reforestation and protection and enhancement of riparian buffers and floodplains. Impervious Area (Cover) - means all impermeable surfaces that cannot effectively infiltrate rainfall. This includes paved, concrete and gravel surfaces (i.e. parking lots, driveways, roads, runways, and sidewalks); building rooftops, and miscellaneous impermeable structures such as patios, pools, and sheds. � The �P+ �I�DUP Page 21 Stormwater Pollution Prevention Plan 176 South Broadway The LA Group Project # 2016144 Municipal Separate Storm Sewer (MS4) — a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains): i. Owned or operated by a state, city, town, borough, county, parish, district, association, or other public body (created by or pursuant to State law) having jurisdiction over disposal of sewage, industrial wastes, stormwater, or other wastes, including special districts under State law such as a sewer district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or a designated and approved management agency under section 208 of the CWA that discharges to surface waters of the State. ii. Designed or used for collecting or conveying stormwater iii. Which is not a combined sewer iv. Which is not part of a Publicly Owned Treatment Works (POTW) as defined at 40 CFR 122.2. Notice of Intent — a standardized format notification sent to the NYSDEC to inform them of the proposed activity to be sent after the SWPPP has been completed. Owner or Operator — means the person, persons or legal entity which owns or leases the property on which the construction activity is occurring; and/or an entity that has operational control over the construction plans and specifications, including the ability to make modifications to the plans and specifications. Post-Construction Stormwater Management Practices — permanent devices constructed or installed onsite to treat stormwater from a site when construction is completed. Qualified Inspector - means a person that is knowledgeable in the principles and practices of erosion and sediment control, such as a licensed Professional Engineer, Certified Professional in Erosion and Sediment Control (CPESC), Registered Landscape Architect, New York State Erosion and Sediment Control Certificate Program holder or other Department endorsed individual(s). It can also mean someone working under the direct supervision of, and at the same company as, the licensed Professional Engineer or Registered Landscape Architect, provided that person has training in the principles and practices of erosion and sediment control. Training in the principles and practices of erosion and sediment control means that the individual working under the direct supervision of the licensed Professional Engineer or Registered Landscape Architect has received four (4) hours of Department endorsed training in proper erosion and sediment control principles from a Soil and Water Conservation District, or other Department endorsed entity.

It is prepared in accordance with the New York State Department of Environmental Conservation (NYSDEC) Stormwater Management Design Manual, dated January 2015. The Project has been designed in accordance with Chapter 4 of the NYSDEC Stormwater Management Design Manual (SWMDM), and NYSDEC's General Permit GP-0-20-001 for construction activities. Stormwater calculations were performed utilizing widely accepted engineering methodologies, including TR-55, and the stormwater modeling computer program HydroCAD (version 10.00)produced by HydroCAD Software Solutions, LLC. 2.0 PROJECT DESCRIPTION 21 Site Location The Project is located off South Broadway in Saratoga Springs, Saratoga County, NY 12866. Access to the site is off both South Broadway and Lincoln Avenue. 2.2 Project Description The proposed proj ect involves the development of a four (4) story hotel located on the east side of South Broadway approximately 250 feet south of the intersection of South Broadway and Lincoln Avenue. The property is currently a two-story motel with a portion of undeveloped woodland. The remainder of the proposed site improvements includes construction of a parking lot, site lighting, landscaping, stormwater controls, and connections to municipal water and sewer. The project is considered a mix of new and redevelopment project per Chapters 4 and 9 of the SWMDM. The Project Site represents the area that will be disturbed as a result of the Proj ect. 2.3 Soil Conditions/Soil Testing According to the Natural Resources Conservation Service (NRCS) Web Soil Survey, the area surrounding the Project Site is comprised of Windsor loamy sand. The hydrological soil group classification for the soil is `A'. � The LA GROUP � ., �A � P� �M.� „FP���,y��� 4 Stormwater Management Report 176 South Broadway 2016144 2.4 Curve Numbers and Rainfall Data The surface cover for the project area is grass, woods and an impervious driveway. The curve numbers utilized in the modeling were assigned based on cover type and HSG soil classification. The design storms used for the pre-development versus post-development comparison were the 1, 10, and 100-year, 24-hour duration, SCS Type II events. The rainfall amounts for these storms are 2.15, 3.75, and 6.20 inches, respectively. 3.0 EXISTING CONDITIONS The Project area existing condition, for which this stormwater management plan is based, consists of grass, woods and an impervious buildings and parking lots. Under the watershed's existing condition, runoff from the site flows offsite to the west to a catch basin north of Todd Street (Analysis Point 1) and offsite to the North to Lincoln Avenue (Analysis Point 2) both of which enter the City of Saratoga Springs municipal storm sewer system. Analysis Points 1 & 2 were utilized in comparing all pre- versus post-runoff conditions. Refer to drawing "W-1 Existing Conditions Watershed Map," located in Attachment B for more information. Table 3-1 below provides a summary of the existing conditions peak discharge rates for the Project's watershed. Table 3-1 Existing Conditions Peak Discharge Rates Analysis AP-1 AP-2 Point Design Storm (cfs) (cfs) 10-Year 4.64 0.11 100-Year 7.86 0.19 Refer to Attachment B for more information on the existing conditions watershed modeling. 4.0 PROPOSED CONDITIONS Under the watershed's Proposed Condition, stormwater from the Project will continue to discharge to the same points as in the Existing Condition (Analysis Points 1 & 2). The total watershed has generally remained unchanged, as is shown on the drawing "W-2 Proposed Conditions Watershed Map" contained in Attachment C. To meet NYSDEC requirements (see Section 5.0 NYSDEC Design Criteria of this report) underground infiltration chambers have � The LA GROUP L .s .eA I e� _rc+xl � ieeiinyl'.C. 5 Stormwater Management Report 176 South Broadway 2016144 been incorporated into the stormwater management design to mitigate the quality and quantity of stormwater runoff discharged from the Project Site. Table 4-1 below provides a summary of the existing conditions versus proposed conditions peak discharge rates for the Project's watershed.

The Manual includes a five-step process that involves site planning and stormwater management practice selection. The five steps include; • Site planning to preserve natural features and reduce impervious cover, • Calculation of the Water Quality Volume (WQv) for the Site, • Incorporation of green infrastructure techniques and standard SMPs with Runoff Reduction Volume (RRv) capacity, • Use of standard SMPs where applicable, to treat the portion of WQv not addressed by green infrastructure techniques and standard SMPs with RRv capacity, and • Design of volume and peak rate control (where required) The approach of the stormwater management plan was to address the stormwater requirements separately. The five steps were reduced to Site Planning to Preserve Natural Features, Water Quality Volume, Runoff Reduction Volume, Channel Protection Volume, and Overbank Flood and Extreme Storm Attenuation, as discussed in the following sections. Attachment D of this report contains detailed calculations for determining and summarizing the required and provided volumes for Water Quality and Runoff Reduction. In general, the required � The LA GROUP L .s .eA I e� _rc+xl � ieeiinyl'.C. 6 Stormwater Management Report 176 South Broadway 2016144 design criteria (WQv and RRv) were calculated for all areas where site disturbance or green infrastructure techniques are proposed. 51 Site Planning to Preserve Natural Features Within Chapter 3 of The Manual, Table 3.1 Green Infrastructure Planning General Categories and Specific Practices includes a list of planning practices utilized in the planning and design of a project. There are two categories, Preservation of Natural Resources and Reduction of Imperious Cover. Preservation of Natural Resources includes: • Preservation of Undisturbed Areas • Preservation of Buffers • Reduction of Clearing and Grading • Locating Development in Less Sensitive Areas • Open Space Design • Soil Restoration Reduction of Impervious Cover includes: • Roadway Reduction • Sidewalk Reduction • Driveway Reduction • Cul-de-sac Reduction • Building Footprint Reduction • Parking Reduction A Natural Resource Map for Green Infrastructure Planning has been developed which indicates natural resource areas and critical environmental areas to be protected (where feasible). As required in Section 3.6 of The Manual, the map includes (where applicable): • Jurisdictional Wetlands o There are no wetlands located near the proj ect site. • Waterways o No waterways are impacted by the Project. • Wetland Adjacent Area o There are no wetlands located near the proj ect site. • Floodplains o The proj ect is not within the flood plain. • Forest, vegetative cover o Project is designed to maintain as much of the woods as feasible. • Topography/Steep slopes � The LA GROUP L .s �eA I e� _rc+xl � ieeiinyl'.C. 7 Stormwater Management Report 176 South Broadway 2016144 o There are no steep slopes located throughout the project. • Existing soils, including hydrologic soil groups and soil erodibility o See Section 2.3 of this Report. • Drainage Patterns o See Section 3.0 of this Report. • Bedrock/Significant geological features o See Section 2.3 of this Report. The Natural Resource Plan indicates the areas to be avoided and depicts the area most suitable for development. 5.2 Water Quality Volume (WQv) The Water Quality Volume (WQv) requirement is designed to improve water quality sizing to capture and treat 90% of the average annual stormwater runoff volumes. The WQv is directly related to the amount of impervious cover created at a site. The following equation is used to determine the water quality storage volume. WQv = (P)(Rv)(A) 12 Where: WQv = Water quality volume(acre/feet) P = 90% Rainfall Event(1.15" for Saratoga Springs) Rv = 0.05 + 0.009(�where I is percent impervious cover A = Site area in acres The required WQv will be provided by underground infiltration chambers designed in accordance with the SWMDM. The total required WQv for the project is 0.066 ac-ft. Refer to Table 5-1 for a summary of the provided water quality volumes for the Project. Table 5-1 Water Qualit Volume Qv Summar SMP Type Provided (ac-ft) SMP1 Underground Infiltration Chambers 0.066 TOTAL 0.066 Refer to Attachment D for detailed WQv calculations. 5.3 Runoff Reduction Volume (RRv) � The LA GROUP L .s �eA I e� _rc+xl � ieeiinyl'.C. g Stormwater Management Report 176 South Broadway 2016144 Section 4.3 of the Manual states, "Runoff reduction shall be achieved by infiltration, groundwater recharge, reuse, recycle, evaporation/evapotranspiration of 100 percent of the post- development water quality volumes to replicate pre-development hydrology by maintaining pre- construction infiltration,peak runoff flow, discharge volume, as well as minimizing concentrated flow by using runoff control techniques to provide treatment in a distributed manner before runoff reaches the collection system." The Proj ect achieves 100% runoff reduction of the on-site WQv of the proj ect. Utilizing green infrastructure and stormwater management practices with RRv capabilities throughout the project an RRv of 0.066 acre-feet is provided. See Table 5-2 for a summary of the provided runoff reduction volumes for each green infrastructure practice. Table 5-2 Runoff Reduction Volume v Summar SMP Provided (unit) 5.3.1 Conservation of Natural Areas - 5.32 Sheetflow to Riparian Buffers/Filter Strips - 5.33 Vegetated Open Swales - 5.3.4 Tree Planting/Tree Box - 5.3.5 Disconnection of Rooftop Runoff - 5.3.6 Stream Daylighting - 5.3.7 Rain Garden - 5.3.8 Green Roof - 5.3.9 Stormwater Planters - 5.3.10 Rain Tanks/Cisterns - 5.3.11 Porous Pavement - Underground Infiltration Chambers (SMP1) 0.066 TOTAL 0.066(ac-ft) Refer to Attachment D for detailed RRv calculations. 5.4 Channel Protection Volume (CPv) The channel protection volume is reduced using green infrastructure practices (underground infiltration chambers). � The LA GROUP L .s .eA I e� _rc+xl � ieeiinyl'.C. 9 Stormwater Management Report 176 South Broadway 2016144 5.5 Overbank Flood (Qp) and Extreme Flood (Qf� Attenuation The primary purpose of the Overbank Flood (Qp) control sizing criterion is to prevent an increase in the frequency and magnitude of out-of-bank flooding generated by urban development. It requires storage and attenuation of the 10-year, 24-hour storm to ensure post- development peak discharge rates do not exceed the pre-development condition. The intent of the Extreme Flood (Qf� criteria is to (a)prevent the increased risk of flood damage from large storm events, (b) maintain the boundaries of the pre-development 100-year floodplain, and (c)protect the physical integrity of stormwater management practices. It requires storage and attenuation of the 100-year, 24-hour storm to ensure post-development peak discharge rates do not exceed the pre-development condition. During the 10-year and 100-year 24-hour storm the post-development peak discharge rates do not exceed the pre-development rates. See Table 4-1 of this Report for detailed comparison of pre- and post-development peak rates. 6.0 PROPOSED STORMtiVATER FACILITIES The Project is proposing the installation underground infiltration chambers to address stormwater requirements for the project. The underground infiltration chambers (SMP-1) are located to the northeast of the proposed building and will treat the runoff from the proposed parking lots. 61 Pretreatment Pretreatment of runoff contributing to SMP-1 is pretreated by an isolator row. 6.2 Treatment Treatment for runoff entering the underground infiltration chambers is provided by capturing and treating the entire WQv though infiltration into the underlying soils. 7.0 POST-CONSTRUCTION MAINTENANCE REQUIREMENTS Larkin Hospitality will be responsible for the continuous upkeep and maintenance of all stormwater management facilities. Maintenance includes, but is not limited to, cleaning of sediment from drainage inlet sumps, removal of sediment from SMPs, cleaning conveyance piping and channels of obstructions, inspection and repair as required of any outlet control mechanisms, and repairing any other detriments in the design that is resulting in the facilities to not function as intended in the design. � The LA GROUP L .s eA I e� �M.I „Fe�i�,yl�C IO Stormwater Management Report 176 South Broadway 2016144 7.0 REFERENCES 1.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/ portal/nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 5 Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of ineasurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics forthe components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and 6 Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 8 Custom Soil Resource Report � Soil Map � a a 598680 598700 598720 598740 598760 598780 43°4'24"N A 'r'°� � � �f I � � 43°4'24"N � � � ��t; ,°ti , r.��i7 . �� am .. :" � ' -' .: a;`�, i ,<rt �. � ,I �,.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Wthin a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, 11 Custom Soil Resource Report onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Saratoga County, New York WnA—Windsor loamy sand, 0 to 3 percent slopes Map Unit Setting National map unit symbol: 2svkg Elevation: 0 to 990 feet Mean annual precipitation: 36 to 71 inches Mean annual airtemperature: 39 to 55 degrees F Frost-free period: 140 to 240 days Farmland classification: Farmland of statewide importance Map Unit Composition �ndsor, loamy sand, and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

Bdway, Saratoga Springs Karner Blue Butterfly and Northern Long Eared Bat Habitat Evaluation The USFWS and NYSDEC on-line mapping shows the site as being an area that may include critical habitat for the Karner Blue butterfly (Lycaeides melissa samuelis),Frosted Elfins (Callophrys irus) and the Northern Long Eared Bat(Myotis septentrionalis). Yesterday, I investigated the site and found that most of the site is occupied by an existing hotel, asphalt parking lot,pool and landscaped lawn and perimeter gardens with annual and perennial plants that do not provide Karner Blue or Frosted Elfin Butterfly habitat. Both species of butterflys rely on wild blue lupine(Lupinus perennis), the only host plant for Karner Blue butterflys and the primary host plant for the Frosted Elfins. Frosted Elfin also rely on the leaves and stems of Wild Indigo (Baptisia spp.),primarily the native Baptisia tinctoria in New York There was no sign of these plants during my investigation.

The building will have underground parking, a swimming pool, fimess center, bar/lounge and a total of 120 sleeping units. The property is currently a motel. Municipal water exists within South Broadway. Municipal sewer exists on the East side of South Broadway. Water will be supplied for domestic and fire protection through a new 6-inch branch lateral which will connect to the 12-inch main on South Broadway. This existing 12-inch main is owned by the City of Saratoga Springs. For sanitary sewer collection, a new connection will be made to the existing manhole on the east site of South Broadway which is currently connected to the municipal system. IL Proiect Description The proj ect proposes a four story hotel with associated access drives,parking areas, landscaping and stormwater management. The building includes 120 guest units. IIL Existin� Water and Sanitary Sewer Utilities Municipal water service is currently provided by the City of Saratoga Springs. A 12-inch diameter water main is located within South Broadway. Northeast Fire Protection Systems Inc. conducted a hydrant flow test on March 27, 2018 on the 12" water main in South Broadway between Canfield Street and Adelphi Street. The results of this flow test indicate a static pressure of 73 pounds per square inch (psi). During the flow test hydrants running at approximately 1,060 gallons per minute caused the residual pressure to drop approximately 63 psi giving a theoretical available flow of approximately 2,607 gallons per minute at 20 pounds per square inch (psi). Refer to Attachment A for the Hydrant Fire Flow Test Summary. Municipal sanitary sewer service is available from the City of Saratoga Springs at a sanitary sewer manhole located adjacent to the proposed building. Wastewater entering this manhole is conveyed by 1 Engineering Report 176 South Broadway Larkin Hospitality 2016144 gravity to the South and ultimately flows for conveyance and treatment at Saratoga County Sewer District's wastewater treatment plant in Mechanicville. IV. Proiected Water and Wastewater Flows The tables below provide information on the anticipated wastewater flow rates for the project: 120 Sleeping Units 110 gpd/unit 13,200 gpd 12 Employees 15 gal each 180 gpd 55 Seat Bar/Lounge 20 gal/seat 1,100 gpd Total 14,480 gpd For the entire proj ect, average daily flow for wastewater is estimated to be 10.1 gallons per minute(gpm)based on a 24-hour day. Estimated peak hourly flow is 41.5 gpm (4.11 x average).� The estimated population served is based on 2 people per sleeping unit and 12 employees (252 total). Average daily demand for water is estimated to be approximately equal to the wastewater flow or 9.3 gpm. Instantaneous demand is calculated at 1.4 gpm3 for each unit giving a total instantaneous demand of 168 gpm. Summary of Design Flows Water Consumption: Proj ect ADF = 14,480 gal/day (gpd) Instantaneous Water Use = 168.0 gal/min (gpm) Sanitar�v Sewer Flows: Proj ect ADF = 14,480 gal/day (gpd) Peak Hourly Flow (PHF) = 41.5 gal/min (gpm) For the purposes of input into the City of Saratoga Springs water model, we offer the following estimated water demands for the proj ect: • Average Day Demand is 10.1 gallons per minute(GPM) over the 24-hour period. • Max Day Demand is 20.2 gallons per minute(GPM)based on twice the average. • Peak Hourly Flow is 41.5 gallons per minute(GPM)based on 4.11 times the average. • Fire Flow Demand is 1,000 gallons per minute (GPM)per ISO guidelines. 2 Engineering Report 176 South Broadway Larkin Hospitality 2016144 V. Pronosed Water and Wastewater Utilities Proposed Water Utilities To service the project, the existing 12-inch ductile iron waterline on South Broadway is proposed to be wet tapped. A new 6-inch lateral will be provided off the existing 12-inch waterline in South Broadway and include a 6" gate valve, and thrust block. Needed Fire Flow (NFF) calculations using the ISO Guide for Determination of Needed Fire Flow are presented in Attachment B. The calculation shows a NFF of 2,250 gallons per minute. This calculation is for a non-sprinklered building. For a building protected by an automatic fire sprinkler system, the ISO states: "The NFF for residerztial occupancies (such as apartment buildings, lodgings and rooming houses, board arzd care facilities, hotels, motels and dormitories)protected by an automatic fire sprinkler system installed in accordance with the general criteria ofNFPA 13R, Standard for the Installation of Sprinkler Systems in Residential Occupancies up to and including Four�Stories in Height, is the demand at the base of the automatic sprinkler riser". "The minimum NFF is 1,000 gpm at 20 psi for a duration of 2 hours". Using the minimum given by ISO, the NFF for this facility is 1,000 gpm. Hydrant flow test data indicates approximately 2,600 gpm available at 20 psi. Based on this information, there is adequate fire protection water supply available at the site. Connections and appurtenances, including tapping sleeves and valves, mechanical joints, thrust blocks, trenching, bedding, as well as testing and disinfection will all be specified in accordance with City of Saratoga Springs standards. A backflow preventor will be located within the proposed building. Proposed Wastewater Utilities Sanitary wastewater will be piped from the building via six-inch PVC lateral installed at a minimum slope of 2.0%to the existing sanitary manhole located near the corner of South Broadway and Todd Street. Peak hourly flow is estimated to be 38.6 gpm for the project. The sanitary sewer lateral and manhole connections will be furnished, installed and tested according to City of Saratoga Springs standards.
