Five residential buildings and a dining hall, located as infill on existing parking lots and recreational fields within the greater Cornell North Campus residential community. The majority of the square footage for the project is in the City of Ithaca. For more detail, see pages 11-14 and 18-.23 of the July 12, 2018 Review Application Report. ARCHITECTURE The buildings remain the same in terms of height, massing and location. The footprints for the Sophomore site remain the same. On the first-year site, the footprints of the longest buildings facing Cradit Farm Drive (buildings 3 and 5) have been shifted in the center. Entrances have been created at these break points to activate the center of the building. The building facades will primarily be terra cotta panels with windows. The colors on the long facades of the buildings will be complementary shades of reds and reddish browns. The ends of the buildings will be shades of grey. Please see the images below. Elevations of all of the buildings are provided in the technical drawing set. Terra Cotta Mock-up with range of colors being considered. 5 of 19 First-Year Site, Interior Quad Perspective First-Year Site, Interior Quad Elevation 6 of 19 Sophomore Site, Looking South Across Jessup Road Perspective Sophomore Site, Looking South Across Jessup Road Elevation 7 of 19 ZONING The project is compliant with land-use regulations in each municipality. For more detail, see page 15 of the July 12, 2018 Review Application Report. SITEWORK Circulation and access remains largely the same as submitted in the SEQR documents. Pedestrians Small revisions to widths of paths and plazas have been made as the design has developed, primarily in response to accommodating emergency access. There are walkways connecting all of the buildings to the greater campus system, enhanced pedestrian crossings across Jessup Road and Cradit Farm Drive and ADA access to every building. An ADA compliant connection between the sophomore site and the first-year site is included as well. Walkways and plazas are shown in the illustrated plan, layout plans and grading plans in the technical documents. Traffic & Parking Vehicular routes and traffic volumes remain the same as submitted in the SEQR documents. Refer to pages 155-166 of the July 12, 2018 Review Application Report. Overall parking counts and strategies remain the same. The following minor changes, (which result in a total reduction of two parking spaces), have been made as the project design has progressed: Sophomore Site RPCC Lot now has 101 spaces proposed (previously 103) Donlon Hall – no change (10 spaces) Akwe:Kon now has 14 spaces proposed (previously 13) Service at the new dining center – no change (5 spaces) First-Year Site Program House Drive now has 45 spaces proposed (previously 42) Appel Commons now has 73 spaces proposed (previously 77) Service at Mews Hall – no change (5 spaces) Service at Appel Commons – no change (2 spaces) Bicycles The project will meet LEED standards for bicycle racks through a combination of exterior bicycle racks and interior bicycle storage. LEED requirements are as follows: Provide long-term bicycle storage for at least 30% of regular building occupants (residents and employees) Provide short-term bicycle storage within 100 feet walking distance from any main entrance for at least 2.5% of peak visitors Bicycle rack locations and interior storage spaces for bicycles are included in the drawing set. A bicycle repair station is proposed at both the sophomore and first-year sites as well. The bicycle route along Cradit Farm Drive, as identified in the SEQR documents, will be completed as a part of this project. 8 of 19 Transit As described in the SEQR documents, north campus is robustly served by multiple bus routes and convenient stops. The bus stops at RPCC on Jessup Road and at Appel Commons on Cradit Farm Drive have been enlarged to accommodate transit vehicles. Two bus shelters to accommodate the anticipated ridership at each location are proposed. Cornell University has been actively working with TCAT to prepare for the project, both during construction and after completion. Attached, please find a letter from TCAT verifying their knowledge of the project and ability to meet the needs of North Campus. Emergency Access The design team has been actively coordinating emergency access needs with Tom Parsons, City of Ithaca Fire Chief, Bruce Bates, Town of Ithaca Codes Officer and Cornell University Environmental Health and Safety. We believe the project meets the emergency access needs for the site. Included in the technical documents are two fire access diagrams. These illustrate the emergency access routes, demonstrate truck-turning ability for the IFD ladder truck (the largest fire-service vehicle), and locate fire hydrants, fire department connections, aerial access set-up locations and roof stairs. Site Layout As the project has developed beyond Schematic Design, the following minor changes to the site have been made since the SEQR submission: • Modest entry courts have been added at the east side of Buildings 3 and 5. • The basketball court at the corner of Jessup Road and Pleasant Grove Road has been removed. • The connector path between the two sites is now curvilinear instead of straight. • Pathways and stair layout between Building 4 and Appel Commons have been revised. • Site design of the sloping courtyard created by Building 4 has been simplified. Site Lighting Consistent with and as described in the July 12, 2018 Review Application Report, project site lighting is proposed as darky sky compliant fixtures that include cutoffs to focus lighting in needed areas and minimize light spillover into adjacent areas. Site lighting will be LED with a color temperature of 3,500K. Pole- mounted fixtures are proposed for the parking areas, along pedestrian walkways and within the residential quads. Pole-height will be scaled according to use, with taller fixtures in the parking lots and shorter fixtures in pedestrian areas. Site light locations are included on the layout plans in the technical documents. Cut sheets for specific fixture choices will be provided prior to final site plan approval. Landscaping We asked our arborist, Bryan Dening, to review the impacts to trees against the current drawing set and compare it to his initial findings which were submitted as part of the July 12, 2018 Review Application Report. Below is a chart, created by Mr. Dening, which notes the changes to tree removals since schematic design. The first number in each column is the tree quantity shown in the current proposed plans, and the second number, in parenthesis, is the quantity shown in the schematic design plans, which were the basis for Mr. Dening’s initial report for SEQR review. The final column explains any changes in the plans. Individual tree removals are shown on the site demolition plans in the technical drawing set. 9 of 19 Detailed planting plans are also included in the technical drawing set. Large species tree planting will meet or exceed the 320 noted as proposed in the SEQR documents (page 89). The landscape palette includes shade trees, ornamental trees, evergreens, shrubs, perennials, lawns and low-mow areas with an emphasis on native species and seasonal interest. Site Materials Furnishings and cut sheets will be provided prior to final site plan review. Paving materials will consist of granite curbs, asphalt and concrete. Where there are emergency access routes, heavy duty paving materials will be used. The recreational field will be artificial turf. Site materials are identified on the landscape layout sheets of the technical drawing set. Updated Visualizations Three aesthetic resource images included in the SEQR documents made note that the views would be enhanced through modified design. Changes to the design have been made to improve views 7 (Sisson Place Looking East), 13 (Jessup Road Looking South) and 14 (Pleasant Grove Road Looking Southwest). 10 of 19 View Point 07 : Sisson Place Looking East Existing View (below): The view looking northeast along Sisson Place is taken from the pedestrian sidewalk at the intersection of Triphammer Road and Sisson Place, north of the entrance to Kappa Delta. In the foreground the south side of Sisson Place pedestrian sidewalk and a mature oak tree are visible. In the midground a stand of trees, lawn and the entrance to the Delta Gamma parking lot are visible. In the background the northwestern façade of Clara Dickson Hall, the south and southwestern façade of George Jameson Hall and the eastern façade of Sigma Alpha Mu are visible. In the background center an oak is visible, behind that in the distant background the eastern façade of Mary Donlon Hall is partially visible through a stand of trees. 11 of 19 Proposed view from SEQR documents (below): The original proposed view noted: “As the project develops beyond Schematic Design (upon which this visualization is based), the site plan will be modified to provide visual screening of the loading dock using evergreen trees in addition to the fence already shown. This enhancement will be included in the Site Plan Review submission. 12 of 19 Modified/Current Proposed View (below): Additional fencing, shrub and evergreen landscape screening has been added to the plans to screen views of the loading dock to the extent practicable. 13 of 19 View Point 13 : Jessup Road Looking South Existing View (below): The view looking south at the intersection of Jessup Road and Pleasant Grove Road is taken from the pedestrian curb ramp on the north side of the crossing. The view includes the south and east facades of the Hasbrouck Apartment complex, the north south pedestrian crossing of Jessup Road and the basketball courts. In the midground an open lawn populated with white pine and sugar maple can be seen. In the background the recreation fields are visible. 14 of 19 Proposed view from SEQR documents (below): The original proposed view noted: “As the project develops beyond Schematic Design (upon which this visualization is based), the site plan will be modified to provide attractive landscape treatments at this corner. We will explore adjustments to the outdoor recreation and grading to create more greenspace for landscape screening.” 15 of 19 Modified/Current Proposed View (below): The basketball court has been removed from the plans, leaving more room for pathways, landscape and grading. Additional tree and shrub plantings are included in the background, and evergreen planting to soften foreground views of the recreation field is proposed. 16 of 19 View Point 14 : Pleasant Grove Road Looking Southwest Existing View (below): The view from Pleasant Grove Road looking southwest across the campus is taken from the shoulder on the northbound side of Pleasant Grove Road. Pleasant Grove Road is in the immediate foreground. A large oak and small pine tree stand beside the road on the southbound side. The midground is an extensive grass playing field, beside which is an asphalt path with pedestrian-scale lighting along the edge. Just beyond the midground, some Cornell buildings can be seen, including Appel Commons, Helen Newman Hall, The Olin Chemistry Research Lab, Mews Hall and Just About Music. The distant background is of Ithaca’s West Hill. 17 of 19 Proposed view from SEQR documents (below): The original proposed view noted: “As the project develops beyond Schematic Design (upon which this visualization is based), the site plan will be modified to provide additional landscape in this view.” 18 of 19 Modified/Current Proposed View (below): Groupings of trees, shrubs, evergreens and ornamental grasses have been added to the foreground and midground to enhance this view. 19 of 19 STORMWATER MANAGEMENT The strategy and approach to managing stormwater remains the same as described on pages 74-77 of the July 12, 2018 Review Application Report. As the project design has advanced, the stormwater management has been updated and revised. A copy of the Stormwater Pollution and Prevention Plan (SWPPP, Volume 1) is included at the end of this letter. One copy of the engineering calculations booklet (SWPPP, Volume 2) has been provided under separate cover for staff review. ENERGY The project is still on track to achieve an energy savings of 35% less than code, earn 20 LEED credits in the energy category and employ all of the energy saving measures described in the July 12, 2018 Review Application Report. For more detail, see pages 169-211 of the Application Report, the supplementary materials sent on September 5, 2018, September 17, 2018, October 12, 2018, November 14, 2018 as well as the Planning Board presentations made during the fall of 2018. CONSTRUCTION SEQUENCING Upon receipt of preliminary site plan approval from the City of Ithaca, the project will apply for an earthwork and foundation permit. Work within the city limits will be started as early as possible this spring. In addition, we are hoping to receive approval to utilize the contractor field offices and parking areas in the Village of Cayuga Heights as early in the spring as possible. The construction field offices are to be located on the existing tennis and basketball courts on the north side of Jessup Road across from the project. The contractor plans to install gravel over areas that are not paved, and will restore the site to its original condition at the completion of construction. Contractor parking is proposed in the open field area north of A-Lot. The contractor plans to install geotextile fabric, gravel and millings and stripe the area to provide a temporary and stable, clean and orderly parking area. The contract will restore the site to its original condition at the completion of construction. Attached please find construction logistic drawings from Welliver, who will be the GC for the project. The drawings include anticipated site sequencing, contractor parking, field office locations, delivery staging and construction routing. MOVE-IN DAY Cornell University has developed a plan for managing move-in day. Please see the attached letter. Pat Wynn Assistant Vice President Student & Campus Life 2336 South Balch Hall Ithaca, NY 14853 February 7, 2019 To: Tom Parsons, City of Ithaca Fire Chief JoAnne Cornish, City of Ithaca Director of Planning Lisa Nicholas, City of Ithaca Deputy Director of Planning From: Pat Wynn, Assistant Vice President for Student & Campus Life Subject: Cornell University’s Move-In Day Update on Future Plans I’m writing to follow up on our Move-In Day recap to you dated October 19, 2018. As you know, we committed to convene a committee to review the move-in day process, as well as other major events that are held on campus and impacted by limited access to residential buildings and by the closing of the CC Parking Lot on north campus. Since that time, we brought together a large group of knowledgeable staff from across the campus, and that group is nearly prepared to issue recommendations to vice presidents Lombardi and Burgess on our processes and policies. A major part of our discussions were directly related to the possibility of securing an outside vendor that provides move-in services. At this point, we are committed to expanding our move-in process to 1 ½ days or more, and are committed to using the services of an external vendor that specializes in move-in services. Guest vehicles will not be permitted on fire apparatus access walkways. We appreciate your willingness to partner and assist us in our planning process and will be contacting you to join our next meeting with representatives from the move-in service vendor. As we discussed, we will increase the communication and coordination capabilities within the command post to include USS supervisory staff, and enhancements to our Incident Action Plan will use the guidance and best practice logic regarding special requirements for Public Safety noted in the Fire Code. Thank you for your time and interest, and we look forward to our continued partnership. cc: Ryan Lombardi, Vice President for Student & Campus Life Rick Burgess, Vice President for Facilities & Campus Services Cornell University Planning Committee This page intentionally left blank.

Miller, P.C. 1. February 8, 2019 PROJECT INFORMATION Project Name and Description Cornell University Undergraduate Student Housing City of Ithaca, Town of Ithaca, Village of Cayuga Heights Tompkins County, New York Operator’s Name and Address Cornell University c/o Chris Davenport, CCM Project Manager Infrastructure, Properties & Planning 102 Humphreys Service Building Ithaca, New York 14852 PROJECT DESCRIPTION Purpose and Extent of Proposed Development The Undergraduate Student Housing project is located on near the far northeast corner of the City of Ithaca. Certain areas of the project are located with the City of Ithaca, the Town of Ithaca and the Village of Cayuga Heights, all within Tompkins County, New York. The project will redevelop a significant portion of North Campus including the removal one fraternity house, parking areas and pedestrian and vehicle access drives, and the construction of five new student residence buildings with associated access drives, pedestrian paths, parking areas, plazas and other site amenities. The project will disturb approximately 26.0 acres of land within a larger 70-acre watershed. The stormwater management objectives focus on controlling erosion and sedimentation during construction and treatment of runoff from the post-developed site. Given the area of disturbance is greater than one acre, a full Stormwater Pollution Prevention Plan (SWPPP) is required, including both erosion controls and permanent stormwater management practices under the regulations of the local municipalities and the New York State Department of Environmental Conservation (DEC). Stormwater management objectives for the site include: · Control erosion of soils and the discharge of sediment from the site during construction utilizing temporary practices. · Providing water quality treatment for post-development conditions primarily through the use of bioretention filter practices. · Maintain existing hydrologic conditions for the subareas of the watershed discharging to municipal storm sewer systems. Project Disturbance Area A majority of the lands to be disturbed by the project are located within the City of Ithaca (58%) and the Town of Ithaca (36%) with a relatively smaller area of the disturbance within the Village of Cayuga Heights (6%). Table 1. Disturbance by Municipality Municipality Area of Disturbance City of Ithaca 15.1 acres Town of Ithaca 9.3 acres Village of Cayuga Heights 1.6 acres Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 2. February 8, 2019 The project will result in an overall increase in impervious cover of approximately 2.5 acres as indicated in the following table: Table 2. Pre- and Post-Development Soil Cover Soil cover Existing Proposed Delta Pervious 15.2 acres 11.4 acres -3.8 acres Impervious 10.8 acres 13.3 acres 2.5 acres Artificial turf 0.00 acres 1.3 acres 1.3 acres Total Disturbance 26.0 acres 26.0 acres A breakdown by subarea of the areas of disturbance and the soil covers under existing conditions and redeveloped conditions are shown on the attached watershed maps. Description and Limitations of On-Site Soils Soils original to the site, prior to more recent development, were most likely Hudson Silty clay loam (90%) and Rhinebeck silt loam (10%) based on soil mapping from the Natural Resources Conservation Service (NRCS) for neighboring lands to the east with similar geological formations. The site is located within ‘unsurveyed’ lands on the NRCS mapping. The NCRC lists the natural drainage class for the Hudson soils as “moderately well drained” and Rhinebeck soils as “somewhat poorly drained.” Both soils are listed as belonging to Hydrologic Soils Group C/D. Recent geotechnical investigations have been completed by John P. Stopen Engineering LLP. The results of the investigation are presented in the attached reports titled “Report of Geotechnical Engineering Evaluations for Foundation Design for Site #1 – CC Lot” and “for Site #2 – Appel Fields” both dated February 7, 2018. The reports confirm the overlaying soils are generally silt or silty loam type soils intermixed with more granular imported materials generally closer to the surface. Below the surface improvements and silt layer are ‘glacial tills’ which are generally over 10’ feet below grade. Glacial till is loamy material that is highly compacted and generally impervious. The depth of the ‘till’ is such that it generally will not be disturbed and will not affect site drainage. Groundwater on the site is generally 6 feet or more below surface and will generally not impact surface drainage. Relatively limited areas at the lower levels of the buildings will likely encounter ground water, and subsurface drainage will be necessary at these locations. Given the depth of groundwater, the intermixing with imported granular materials and the existence of surface and below-grade drainage improvements on the site, the site soils are generally considered moderately well drained, and all hydrologic calculations consider the site soils as belonging to Hydrologic Soils Group C. In general, the ‘tight’ soils on the site preclude employing formal infiltration practices to manage and/or treat stormwater runoff. Bioretention filters will be employed as the predominate practice to treat runoff from the site following completion of the project. Archeological Protection and Historic Preservation Based on New York State Historic Preservation Office (SHPO) mapping the project is not located on lands that are archeologically sensitive, or are listed or eligible for listing on the State or National Register of Historic Places. An archaeology study of the project has concluded that no cultural deposits remain in the project area due to previous disturbance associated with development of North Campus. The project is currently being reviewed by SHPO in conjunction with the environmental review for the overall project. The project is located adjacent to the locally designated Cornell Heights Historic District. The district, which is also listed in the National Register, is located generally to the west of the project site. The proposed building closest to the historic district, Building 1, will be greater than 100 feet away from the closest existing structure within the district. Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 3. February 8, 2019 Wetlands There are neither federal nor state wetlands located on the site. Name of Receiving Waters All stormwater runoff from the site discharges ultimately to Fall Creek and Cayuga Lake. Runoff from Subareas 1 and 2 discharges to the north side of Jessup Road in existing Cornell storm sewers which are tributary to drainageways generally within the Village of Cayuga Heights which discharge to Fall Creek near the Ithaca High School. Runoff from Subarea 3 discharges to the City of Ithaca storm sewer system on Triphammer Road near the Sisson Place intersection. The City storm sewer system discharges to Fall Creek below the Thurston Avenue bridge. Runoff from Subareas 4 and 5 discharges directly to Fall Creek at Beebe Lake above the Thurston Avenue bridge and Beebe Lake Dam. Floodplains Based on a review of the current FEMA Flood Insurance Rate Maps for the City and Town of Ithaca, the project is located in Flood Zone C which are areas of minimal flooding above the 500-year flood boundary. SEQUENCE OF MAJOR ACTIVITIES Major activities for each phase of this site include but are not limited to: · Installing temporary control measures as shown on the plans. · Completing site demolition and clearing. · Performing building, pavement and site grading earthwork operations. · Installing drainage and utilities improvements on the site. · Installing asphalt pavements. · Restoring existing soils, seed and mulch. · Removing temporary practices. It shall be the responsibility of the Contractor to make any changes to the SWPPP necessary when the Contractor or any of the subcontractors elect to use borrow or fill or material storage sites, either contiguous to or remote from the construction site, when such sites are used solely for this construction site. Such sites are considered to be part of the construction site covered by the permit and this SWPPP. Off-site borrow, fill, or material storage sites which are used for multiple construction projects are not subject to this requirement, unless specifically required by state or local jurisdictional entity regulations. The Contractor should consider this requirement in negotiating with earthwork subcontractors, since the choice of an off-site borrow, fill, or material storage site may impact their duty to implement, make changes to, and perform inspections required by the SWPPP for the site. POST-CONSTRUCTION STORMWATER MANAGEMENT Existing Conditions The 26.0 acres of land to be disturbed by the project have been previously developed and disturbed. The greenspaces have been previously graded and the top soil levels are fill soils. The project is considered redevelopment as defined in the NYSDEC Stormwater Design Manual which states that redevelopment projects “conserve natural resources in less impacted areas by targeting development to areas with existing services and infrastructure. At the same time, redevelopment provides an opportunity to correct existing problems and reduce pollutant discharges from older developed areas that were constructed without effective stormwater pollution controls.” Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 4. February 8, 2019 As shown on the attached Watershed Maps for the existing and proposed conditions, the project is located within a larger approximate 70-acre watershed which covers a large portion of North Campus extending as far east as the Hasbrouck Apartment complex east of Pleasant Grove Road. Five separate subareas within the watershed, each with distinct outfalls have been identified. Subareas 1 and 2 are generally located along the George Jessup Road corridor with their respective outfalls discharging toward the north and west to the Village of Cayuga Heights. Significant portions of these subareas are within the Village of Cayuga Heights and City of Ithaca, with a relatively smaller area to the east within the Town of Ithaca. Stormwater runoff from these subareas discharges to University-owned storm sewers on the north side of Jessup Road before flowing generally within open channels and gorges through the Village and City before discharging to Fall Creek near the Ithaca High School. The majority of Site 1 improvements are located within Subarea 3. Stormwater runoff from the subarea is collected by the existing onsite storm drainage system which discharges to the City storm sewer collection system at the outfall on Triphammer Road. The runoff flows in the City system generally to the south and east before discharging to the Fall Creek Gorge below the Thurston Avenue Bridge. Subareas 4 and 5 cover a large area of North Campus generally to the east. The majority of the Site 2 improvements are located within these 2 subareas. Stormwater runoff from these subarea is collected by existing onsite storm drainage systems. The outfalls for these subareas are located to the south of the Site 2 where stormwater runoff discharges to Beebe Lake on Fall Creek. Similar to all the watershed outfalls, the outfalls for Subareas 4 and 5 are located within the City of Ithaca. Prior to discharging to Beebe Lake, stormwater runoff from the subareas is treated by two existing hydrodynamic treatment facilities installed upstream of each outfall. Fall Creek at this location is classified by the NYSDEC as a fifth order stream. Redeveloped Conditions The project will result in relatively minor changes to the onsite drainage patterns, and the drainage areas of the individual subareas will not change significantly. The improvements will also result in changes in soil cover within the respective subareas. The changes to Subareas 1, 2 and 3 are relatively small and will not alter the hydrology of these subareas that discharge to the Village of Cayuga Heights and City of Ithaca storm sewer system. Subarea 1 The project will disturb approximately 1.7 acres of land within the 6.4-acre Subarea 1. Slight changes in drainage patterns will reduce the drainage area within the subarea by less than 0.1 acres. Changes in soil cover will increase impervious soil cover by approximately 0.2 acres resulting in an increase in the Curve Number (CN) from 86 to 87. The treatment practices within the subarea will treat runoff from approximately 0.74 acres of impervious cover including the higher polluting parking area located at the northeast corner of Site 1.

Miller, P.C. 5. February 8, 2019 Subarea 2 The project will disturb approximately 1.3 acre of land within Subarea 2. Minor changes in drainage patterns will increase the drainage area within the subarea from approximately 2.9 acres to 3.2 acres. Most of the 0.3-acre increase will be landscaped areas. The result will be a slight reduction in curve number from CN=86 to CN=85. Treatment practices within the subarea will treat runoff from approximately 0.30 acres of impervious cover, primarily associated with the north wing of Building 2. The minor changes in drainage area and soil cover within Subareas 1 and 2 will not alter the hydrology from pre- to post-development conditions and therefore the project will not result in any effective change to the peak rates or volumes of runoff discharging to the Village of Cayuga Heights storm drainage system. The project will provide water quality treatment for over 1.0 acres of impervious soil cover within the 2 subareas where none is currently provided. Subarea 3 The majority of Site 1 is located within Subarea 3 where the project will disturb approximately 8.2 acres of land which discharges to the City storm sewer system on Triphammer Road. Minor changes in drainage patterns will reduce the drainage area within the 15-acre subarea by approximately 0.3 acres. The minor changes in soil cover will result in no change in curve number from the current CN=89. The minor reduction in drainage area will therefore result in slight reductions in the peaks rates and volumes of runoff from the subarea to the City storm system. Treatment practices within the subarea will treat runoff from approximately 1.40 acres of impervious cover within the subarea including the higher polluting paved areas associated with the parking areas and Building 1 loading dock. Subarea 4 The project will disturb approximately 2.7 acres of land within Subarea 4 generally associated with the Site 2 area of the project. Changes in drainage pattern will result in an approximate 0.6 acre increase in the 10-acre drainage area within Subarea 4 with a commensurate decrease in drainage area within Subarea 5. Impervious soil cover within Subarea 4 will also increase by approximately 0.7 acres resulting in an increase in the subarea curve number from CN=84 to 85. The increases in drainage area and impervious soil cover will increase the rates and volumes of runoff to be discharged from the subarea to Fall Creek. Given the creek at this location is classified as a fifth order stream, detention of stormwater to attenuate the peak rates of runoff are not necessary. Treatment practices within the subarea will treat approximately 0.4 acres of the approximate 1.6 acres of impervious cover within the area of disturbance. The practices will treat runoff from most if not all of the higher polluting access drive at the westerly edge of Site 2. Subarea 5 Within Subarea 5, the project will disturb approximately 12 acres of land associated with the Site 2 improvements. As noted above, changes in drainage pattern will result in an approximate 0.6 acre decrease in drainage area within the larger 35-acre subarea. The improvements will increase the impervious soil cover by approximately 1.8 acres within the subarea. The project will also add approximately 1.3 acres of artificial turf to the subarea. Given the artificial turf is expected to generate little if any sediment, this area is considered pervious relative to the determining of required amount of quality treatment required on the site. The artificial turf is herein currently assigned a curve number equal to lawn. In conjunction with the future design of the artificial turf field, the hydrological analyses of the subarea will be adjusting accordingly based on information from the turf manufacturer on how best to model the field. Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 6. February 8, 2019 Assuming the artificial turf is hydrologically equal to natural turf (lawn), the project will result in an increase in the curve number for Subarea 5 from CN=84 to 85. The 0.6-acre decrease in drainage area and 1.8-acre increase in impervious soil cover in the subarea will result in a net increase in the rates and volumes of runoff to be discharged from the subarea to Fall Creek. Similar to Subarea 4, runoff from Subarea 5 discharges to a fifth order stream, and detention of stormwater to attenuate the peak rates of runoff from the subarea are not necessary. Treatment practices within the subarea will treat approximately 5.1 acres of the approximate 5.0 acres of impervious cover within the area of disturbance. Similar to the other areas of project disturbance, treatment practices within Subarea 5 prioritize the treatment of runoff from the higher polluting access drives and parking fields but also provide treatment for most of the pedestrian paths and building roof areas within the subarea.

HYDROLOGIC DATA FOR FUTURE CONDITIONS Watershed Drainage Area (Acres) Curve Number Time of Concentration (min) SUBAREA 1 6.4 87 18.0 SUBAREA 2 3.2 85 17.5 SUBAREA 3 14.6 89 23.6 SUBAREA 4 10.8 85 23.5 SUBAREA 5 35.0 85 36.7 TOTAL 70.0 Water Quality Controls Within the 26.0 acres of disturbance the project will increase impervious soil cover by approximately 2.5 acres, from an existing impervious soil cover of approximately 10.8 acres to approximately 13.3 acres under the redeveloped site conditions. The minimum amount of water quality treatment required by the general permit and current NYSDEC redevelopment standards is equivalent to 25% of the existing impervious soil cover plus 100% of the increase in impervious soil cover, or Treatment Required = 25% * 10.8 acres + 100% * 2.5 acres = 5.2 acres (impervious soil cover) The equivalent water quality volume (WQv) required is calculated using the standard equation for WQv as follows: WQv = P * Rv * A / 12 (acre-ft or c.f.) Where: P = 90% rainfall event (inches) = 1.00 inches (Ithaca, NY) Rv = (0.05+0.009*I) I = Imperviousness (%) A = Drainage Area (acre or s.f.) Where: I = 100% A = 5.2 acre WQv = 0.42 acre-ft (required) The required treatment will be provided by installing bioretention filter practices throughout the site in addition to one pre-packed vault-enclosed filter practice (Filter S1-F) located at the Site 1 loading dock. The pre-packaged filter is necessary due to grade and space constraints at that location. Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 7. February 8, 2019 As indicated in Table 5, the filter practices will provide quality treatment for approximately 7.9 acres of the future impervious cover on the site with a total WQv of 0.65 acre-ft or approximately 20% more than required. As noted previously, the areas to be treated will prioritize the higher polluting parking fields, vehicle access drives and loading dock areas proposed. In many cases the site will allow significant oversizing of the filter practices to increase the amount of runoff reduction provided by the practices. The bioretention filter practices are designed to improve water quality by capturing and treating 90% of the average annual stormwater runoff volume from the associated catchment area draining to the individual practices. The required WQv for each practice in Table 5 are calculated from the WQv equation above using s.f. for the areas and c.f. for the WQv’s. The filters are sized using Darcy’s Law as presented in the New York State Stormwater Management Design Manual, using the following equation: A = Filter Practice Catchment Area I = Imperviousness (percent) Af = WQv (df)/[(k)(T)(df+hf)] Where: Af = Filter Area, Required and Proposed (sf) df = Filter Depth (feet) = 2.5 feet hf = Average Head Above Filter (feet) = 0.25 feet Tf = Filtering Time (days) = 2 days k = Soil Permeability (ft/day) = 0.5ft/day WQv = Water Quality Volume (cf) = P*(0.05+0.009*I)*A / 12 *Pre-packaged vault-enclosed filter practice As required by the stormwater standards, all the bioretention filter practices have sufficient volume to temporarily hold at least 75% of the WQv associated with the specific catchment areas draining to the individual practices. Pretreatment will be provided by stone diaphragms and grass filter strips where runoff from paved surfaces sheet flows into the filter practices. Pipes discharging to the practices will TABLE 5.

Miller, P.C. 8. February 8, 2019 be equipped with riprap outlet protection. Shredded hardwood mulch over the filter beds as well as architectural elements featuring quarry blocks will provide an additional level of pretreatment above the filter beds. Based on the soils reports for the project most if not all of the filter practices as designed are expected to have the minimum required 2-foot separation between groundwater and the bottoms of the filters. Groundwater levels across the site are highly variable and the soils reports do not necessarily include boring data at the exact locations of the practices. For these reasons, additional soil exploration will be conducted prior to installation to confirm minimum separation distances. Practices where less than 2 feet of separation is observed will be equipped with impermeable membrane barriers at the subgrade. Practices located above and immediately adjacent to occupied building space will also be equipped with membrane barriers to prevent water intrusion into the buildings. These include Filter S1-C adjacent to Building 2A, and Filters S2-L and S2-M adjacent to Building 5A. Runoff Reduction Volume Although redevelopment projects that meet all the NYSDEC standards for redevelopment are typically exempt from the Runoff Reduction Volume (RRv) criteria, the project will provide runoff reduction in excess of the volume required for new projects. Full runoff reduction can be achieved by infiltration, groundwater recharge, recycling, or evaporation/evapotranspiration of 100 percent of the post-development water quality volumes to replicate pre-development hydrology. Given the imperviousness of the site soils, infiltration capacity is limited, and runoff reduction of the full water quality volume is not feasible. Projects that cannot achieve runoff reductions for 100 percent of the water quality volume must typically, at a minimum, provide runoff reduction equal to a certain percentage of the water quality volume based on the specific Hydrologic Soil Groups (HSG) of the site, which in this case is HSG “C”. The minimum runoff reduction volume required is calculated using the following equation: Min RRv = [(P) (Rv) (Aic) (S)] / 12 Where: P = 90% rainfall event (inches) = 1.00 inches (Ithaca, NY) Rv = 0.05+0.009(I) Where I is 100% impervious = 0.95 Aic = Total area of new impervious cover (acres) S = HSG Specific Reduction Factor = 0.30 for HSG “C” Soils Applying the total post-development impervious soil cover of 13.3 acres results in the following required runoff reduction volume: Min RRv = [(1.00) * (0.95) * (13.3) * (0.30)] / 12 = 0.32 ac-ft (13,939 cubic feet) The proposed bioretention filters not only provide the required water quality volume but are also considered standard stormwater management practices which provide runoff reduction capacity. Such practices when installed with underdrain systems in HSG C soils are credited a minimum RRv of 40% of the water quality volume treated by the practice. When the sizes of the individual practices are greater than the minimum required for quality treatment, the amount of RRv is credited based on 40% of the storage volume of the practice up to a maximum equal to the full water quality volume of the practice. Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 9. February 8, 2019 The storage volumes and RRv volumes of the individual filter practices listed in Table 6 are calculated using the following equation up to the maximum WQv of the practices: RRv = VF * 40% credit (c.f.) < WQv (c.f.) VF = filter storage volume = VSM + VDL + (DP x ARG) VSM = ARG x DSM x nSM VDL = ARG x DDL x nDL Where: VSM = volume of the soil media (c.f.) VDL = volume of the gravel drainage layer (c.f.) ARG = filter surface area (s.f.) DSM = depth of the soil media (2.5 feet) DDL = depth of the drainage layer (1.0 feet) DP = depth of ponding above surface (0.5 feet) nSM = porosity of the soil media (20%) nDL = porosity of the drainage layer (40%) TABLE 6.

Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 10. February 8, 2019 Water Quantity Controls The minor changes in drainage area and soil cover within Subareas 1, 2 and 3 will not alter the hydrology from pre- to post-development conditions and therefore the project will result in only minor changes in the peak rates and volumes of runoff discharging to the Village of Cayuga Heights and City of Ithaca storm drainage system. The increases in rates of runoff from Subareas 4 and 5, which discharge directly to Fall Creek, are allowed under the state standards given the creek at this location is classified as a 5th order stream. The peak rates of flow in the creek are not expected to be impacted by the project given the large differences in time-to-peak between the site and the larger watershed associated with Fall Creek. For these reasons controls related to channel protection, overbank and extreme storm events are not required. Table 7 summarizes the volumes and peak rates of runoff from each of the subareas. The figures for Subarea 4 assume the proposed 1.25 acres of artificial turf is equivalent to lawn. Routing calculations for runoff through the proposed filter treatment associated with Subareas 1 and 2 are used to determine the peak rates of runoff for Subareas 1 and 2 and for the Combined to Village under Redeveloped Conditions. 1-yr 2-yr 10-yr 25-yr 100-yr 1-yr 2-yr 10-yr 25-yr 100-yr Subarea 1 0.42 0.55 1.01 1.39 2.18 6.6 8.6 15.7 21.4 32.8 Subarea 2 0.19 0.24 0.45 0.62 0.97 2.9 3.8 7.0 9.5 14.5 Combined to Village 0.61 0.79 1.46 2.01 3.15 9.5 12.4 22.7 30.9 47.3 Subarea 3 1.18 1.50 2.63 3.54 5.41 15.5 19.7 34.2 45.3 67.8 Subarea 4 0.58 0.77 1.46 2.04 3.26 7.5 10.1 19.3 26.8 42.1 Subarea 5 2.00 2.67 5.09 7.10 11.35 19.2 25.9 50.1 69.7 110.1 Subarea 1 0.39 0.52 0.98 1.35 2.14 6.3 8.9 16.4 22.0 33.4 Subarea 2 0.15 0.20 0.41 0.59 0.97 2.4 3.2 6.9 9.6 15.4 Combined to Village 0.54 0.72 1.39 1.94 3.11 8.7 12.0 23.3 31.6 48.7 Subarea 3 1.16 1.47 2.59 3.50 5.32 15.3 19.4 33.6 44.6 66.7 Subarea 4 0.65 0.86 1.62 2.24 3.54 8.5 11.3 21.3 29.3 45.6 Subarea 5 2.25 2.95 5.45 7.49 11.75 22.2 29.2 54.1 73.8 114.1 Existing Conditions Redeveloped Conditions TABLE 7. HYDROLOGIC MODELING RESULTS Runoff Volume (acre-feet) Peak Rate of Runoff (cfs) Underground Injection Control Permits Stormwater drainage wells are regulated by the Environmental Protection Agency (EPA) through the Underground Injection Control (UIC) program as Class V injection wells with requirements to protect underground sources of drinking water. By definition, a Class V injection well is any bored, drilled, or driven shaft, or dug hole that is deeper than its widest surface dimension, or an improved sinkhole, or a subsurface fluid distribution system. The proposed infiltration practices have depths that are much shallower than their largest surface dimension. The proposed subsurface piping in both practices is acting as a collection system and not as a distribution system. As a result, an UIC permit is not required. Stormwater Signage The owner of post-construction stormwater management practices shall erect or post, in the immediate vicinity of the stormwater management practice, a conspicuous and legible sign of not less than 18 inches by 24 inches (or 10 inches by 12 inches for footprints smaller than 400 square feet) bearing the Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 11. February 8, 2019 following information: Stormwater Management Practice – (name of the practice) Project Identification – (SPDES Construction Permit #) Must be maintained in accordance with O&M Plan DO NOT REMOVE OR ALTER Better Site Design In accordance with the stormwater regulations set forth by the City of Ithaca, projects disturbing more than one acre must apply at least 4 better site design techniques as described the 2008 NYSDEC Better Site Design manual. These practices incorporate non-structural and natural approaches to new and redevelopment projects to reduce effects on watersheds by conserving natural areas, reducing impervious cover and better integrating stormwater treatment. Several techniques described below have been incorporated into the project in order to satisfy runoff reduction requirements and are concurrent with the city requirements: Preservation of Undisturbed, Locating Sites in Less Sensitive Areas Given the project is located on previously developed/disturbed lands, the project inherently incorporates these two better site design practices. Building Footprint Reduction All the proposed buildings will be multi-story and therefore will reduce the footprint of the structures. Parking Reduction The project will result in a net decrease in the amount of parking on North Campus. Bioretention/Rain Gardens Stormwater treatment will be provided primarily by installing bioretention filter practices integrated into the landscape throughout the site. Tree Planting The landscape design includes an extensive amount of trees to be planted throughout the site. Soil Restoration Soil restoration is a required practice applied across areas of a development site where soils have been disturbed and will be vegetated in order to recover the original properties and porosity of the soil. Soil restoration is applied in the cleanup, restoration, and landscaping phase of construction followed by the permanent establishment of an appropriate, deep-rooted groundcover to help maintain the restored soil structure. The required measures of soil restoration are outlined in Table 8. TABLE 8. SOIL RESTORATION REQUIREMENTS Type of Soil Disturbance Soil Restoration Requirement Comments/Examples No soil disturbance Restoration not required Preservation of Natural Features Minimal soil disturbance Restoration not required Clearing and grubbing Areas where topsoil is stripped only – no change in grade Aerate1 and apply 6 inches of topsoil Protect area from any ongoing construction activities Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 12. February 8, 2019 Areas of cut or fill Apply full Soil Restoration2 Heavy traffic areas on site (especially in a zone 5-25 feet around buildings but not within a 5 foot perimeter around foundations walls) Apply full Soil Restoration2 (de- compaction and compost enhancement) Areas where Runoff Reduction and/or infiltration practices are applied Restoration not required, but may be applied to enhance the reduction specified for appropriate practices. Keep construction equipment from crossing these areas. To protect newly installed practice from any ongoing construction activities construct a single phase operation fence area Redevelopment Projects Full Soil Restoration is required on redevelopment projects in areas where existing impervious area will be converted to pervious area 1: Aeration includes the use of machines such as tractor-drawn implements with coulters making a narrow slit in the soil, a roller with many spikes making indentations in the soil, or prongs which function like a mini-subsoiler. 2: Per “Deep Ripping and De-Compaction, DEC 2008.” The underlying soils on the project site are classified as Hydrologic Soil Group “C,” requiring full soil restoration. The required measures of full soil restoration, per the NYSDEC’s 2008 publication of “Deep Ripping and De-Compaction” are as follows: During periods of relatively low to moderate subsoil moisture, the disturbed subsoils are returned to rough grade and the following Soil Restoration steps applied: 1. Apply 3 inches of compost over subsoil. 2. Till compost into subsoil to a depth of at least 12 inches using a cat-mounted ripper, tractor- mounted disc, or tiller, mixing, and circulating air and compost into subsoils. 3. Rock-pick until uplifted stone/rock materials of four inches and larger size are cleaned off the site. 4. Apply topsoil to the depth specified on the landscaping plan. 5. Vegetate per the approved landscaping plan. CONTROLS Erosion and Sediment Controls A layout of applicable erosion and sediment controls measures, together with typical installation details, are depicted on sheet C401 through C423B of the construction drawings. Stabilization Practices The applicable erosion and sediment control measures shall be constructed prior to demolition, clearing or grading of any portion of the project, where applicable. In areas where soil disturbance activity has temporarily or permanently ceased, the application of soil stabilization measures must be initiated by the end of the next business day and completed within fourteen (14) days from the date the current soil disturbance activity ceased, unless construction activities will be resumed within 14 days. On sites where the disturbance is greater than 5 acres of land at any one time, the application of soil stabilization measures must be initiated by the end of the next business day and completed within seven (7) days from the date the current soil disturbance activity ceased. In frozen ground conditions, temporary vegetative measures should be implemented as soon as practical in order to control runoff during snowmelt. Permanent vegetation should be installed within 7 days of the completion of grading activities. If the Qualified Professional determines that permanent seed cannot be applied due to climate conditions, Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 13. February 8, 2019 topsoil shall not be spread and temporary mulching shall be applied to the exposed surface to stabilize soils until the next recommended seeding period. Structural Practices Structural erosion and sediment control practices have been classified as either temporary or permanent, according to how they are used. Temporary structural practices are used during construction to prevent offsite sedimentation. Permanent structural practices are used to convey surface water runoff to a safe outlet. Permanent structural practices will remain in place and continue to function after the completion of construction. Regardless of whether the practices are temporary or permanent, runoff control measures should be the first items constructed when grading begins, and be completely functional before land disturbance takes place. Temporary structural practices used in this project include the following: · Silt Fence · Sediment Logs · Stabilized Entrances · Inlet Protection · Rock Check Dams · Sediment Traps Other Controls Waste Disposal All waste materials will be collected and stored in securely lidded metal dumpsters rented from a local waste management company which must be a solid waste management company licensed to do business in Tompkins County. The dumpsters will comply with all local and state solid waste management regulations. All trash and construction debris from the site will be deposited in the dumpsters. The dumpsters will be emptied a minimum of twice per week or more often if necessary, and the trash will be hauled to a landfill approved by New York State. No construction waste materials will be buried on site. All personnel will be instructed regarding the correct procedures for waste disposal. Notices stating these practices will be posted in the job site construction office trailer, and the job site superintendent will be responsible for seeing that these procedures are followed. Sanitary Waste All sanitary waste will be collected from portable units a minimum of two times per week by a licensed portable facility provider in complete compliance with local and state regulations. Off-Site Vehicle Tracking Stabilized construction exits (Tracking Pads) will be provided to help reduce vehicle tracking of sediments. The paved streets adjacent to the site entrances will be inspected daily and cleaned with vacuum equipment or swept as necessary to remove any excess mud, dirt, or rock tracked from the sites. Dump trucks hauling material from the construction sites will be covered with a tarpaulin. The job site superintendent will be responsible for seeing that these procedures are followed. Hazardous Substances and Hazardous Waste All hazardous waste materials will be disposed of by the Contractor in the manner specified by local, state, and/or federal regulations and by the manufacturer of such products. Site personnel will be instructed in these practices by the job site superintendent, who will also be responsible for seeing that these practices are followed. Material Safety Data Sheets (MSDS's) for each substance with hazardous properties that is used on the job site will be obtained and used for the proper management of potential Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 14. February 8, 2019 wastes that may result from these products. An MSDS will be posted in the immediate area where such product is stored and/or used and another copy of each MSDS will be maintained in the SWPPP file at the job site construction trailer office. Each employee who must handle a substance with hazardous properties will be instructed on the use of MSDS sheets and the specific information in the applicable MSDS for the product he/she is using, particularly regarding spill control techniques. Any spills of hazardous materials which are in quantities in excess of Reportable Quantities as defined by EPA regulations shall be immediately reported to the EPA National Response Center 1-800-424- 8802. In order to minimize the potential for a spill of hazardous materials to come into contact with stormwater, the following steps will be implemented: · All materials with hazardous properties (such as pesticides, petroleum products, fertilizers, detergents, construction chemicals, acids, paints, paint solvents, cleaning solvents, additives for soil stabilization, concrete curing compounds and additives, etc.) will be stored in a secure location, under cover, when not in use. · The minimum practical quantity of all such materials will be kept on the job site. · A spill control and containment kit (containing, for example, absorbent such as kitty litter or sawdust, acid neutralizing powder, brooms, dust pans, mops, rags, gloves, goggles, plastic and metal trash containers, etc.) will be provided at the storage site. · All of the products in a container will be used before the container is disposed of. All such containers will be triple-rinsed with water prior to disposal. The rinse water used in these containers will be disposed of in a manner in compliance with state and federal regulations and will not be allowed to mix with stormwater discharges. · All products will be stored in and used from the original container with the original product label. · All products will be used in strict compliance with instructions on the product label. · The disposal of excess or used products will be in strict compliance with instructions on the product label. Contaminated Soils Any contaminated soils (resulting from spills of materials with hazardous properties) which may result from construction activities will be contained and cleaned up immediately in accordance with the procedures given in the Spill Prevention Control and Countermeasures (SPCC) Plan and in accordance with applicable state and federal regulations. The job site superintendent will be responsible for seeing that these procedures are followed. MAINTENANCE/INSPECTION PROCEDURES Erosion and Sediment Control Inspection and Maintenance Practices The following inspection and maintenance practices will be used to maintain erosion and sediment controls and stabilization measures. · For construction sites where soil disturbance activities are on-going, the Operator’s Qualified Professional shall conduct a site inspection at least once every 7 calendar days. · Per the City and Town of Ithaca Stormwater Laws the Operator’s Qualified Professional shall conduct a site inspection within 24 hours of any rainfall event exceeding 1/2-inch of precipitation. · All measures will be maintained in good working order; if repairs are found to be necessary, they will be initiated within 24 hours of report. · Silt fence will be inspected for proper toe-in depth, depth of sediment, tears, etc., to see if the fabric is securely attached to the fence posts, and to see that the fence posts are securely in the ground. Undergraduate Student Housing Stormwater Pollution Prevention Plan T.G. Miller, P.C. 15. February 8, 2019 Built up sediment will be removed from silt fence when it has reached one-third the height of the fence. · Inlet protection measures will be inspected for accumulation of sediments and debris. Sediment and debris shall be removed without damaging the inlet protection fabric. · Stabilized entrances shall be maintained in a condition that will prevent tracking of sediment onto public rights-of-way or streets. This will require periodic top dressing with additional aggregate in most cases, and complete replacement of aggregate in extreme cases. · Temporary sediment traps will be inspected for depth of sediment, and built up sediment will be removed before it reaches 50 percent of the height of the riser. · Temporary and permanent seeding and all other stabilization measures will be inspected for bare spots, washouts, and healthy growth. · The job site superintendent will be responsible for selecting and training the individuals who will be responsible for these maintenance and repair activities. · Personnel selected for the maintenance responsibilities will receive training from the job site superintendent. They will be trained in all the maintenance practices necessary for keeping the erosion and sediment controls that are used onsite in good working order. They will also be trained in the completion of, initiation of actions required by, and the filing of the inspection forms. Documentation of this personnel training will be kept on site with the SWPPP. · Disturbed areas and materials storage areas will be inspected for evidence of or potential for pollutants entering stormwater systems. · Report to NYSDEC within 24 hours any noncompliance with the SWPPP that will endanger public health or the environment. Follow up with a written report within 5 days of the noncompliance event. Disturbance at Any Time Greater Than 5 acres Disturbance of more than five (5) acres of soil at any one time shall not be allowed without prior written authorization from the City and Town of Ithaca.

Has a long term Operation and Maintenance Plan for the post-construction stormwater management practice(s) been developed? Yes If Yes, Identify the entity responsible for the long term Operation and Maintenance Cornell University; Attn: Chris Davenport 39. Use this space to summarize the specific site limitations and justification for not reducing 100% of WQv required (#28). (See question #32a) This space can also be used for other pertinent project information. The site is separated into 5 sub-areas. Sub-areas 1, 2 and 3 will not alter hydrology from pre- to post-developed conditions and therefore the project will result in only minor changes in the peak rates and volumes of runoff discharging to the Village of Cayuga Heights and City of Ithaca storm drainage system. Subareas 4 and 5 directly discharge to Fall Creek, a fifth-order stream. For these reasons controls related to channel protection, overbank and extreme storm events are not required for this redevelopment project.
