Summary The Cortland County Soil and Water Conservation District (SWCD) implements the Town of Cortlandville post-construction stormwater maintenance inspection program on behalf of the Town. This program consists of 1) annual self-reporting by the 52 facilities currently included in the program, 2) annual facility inspections by the SWCD of approximately one-third of the facilities each year, and 3) limited wet-weather inspections of particular facilities as necessary to evaluate performance. SWCD received self-reporting responses for 90% of the facilities for the 2022 year. All facilities responding reported that their stormwater systems were functioning properly with no problems identified. Most reported that they had inspected and maintained their system at least once during 2022. Several facilities reported that no inspections and/or maintenance had been performed on their property. SWCD will contact these facilities to provide additional information regarding Cortlandville stormwater management maintenance requirements for their properties as described in their Stormwater Pollution Prevention Plans (SWPPPs). The SWCD conducted 16 inspections during 2022. Most of the stormwater systems inspected appear to be functioning properly or require at most minor management actions and most are being adequately maintained and/or repaired. Several facilities may require maintenance or examination by a qualified design professional. Additional information for each facility inspected by the SWCD can be found in Appendix A. 2. Introduction Cortlandville’s post-construction stormwater maintenance inspection program began in 2013 as part of a broader stormwater management program designed to implement the Town’s stormwater management ordinance. The broader stormwater program has several components. The Cortland County Soil and Water Conservation District (SWCD) reviews the draft SWPPP and design details on behalf of the Town Planning and Zoning Board. If the project is approved for construction by the Board, the Town Code Officer ensures that installation of post- construction stormwater facilities is consistent with design plans. Finally, the SWCD implements, on behalf of the Town, a stormwater inspection program for commercial and industrial properties that have post-construction stormwater management facilities. This report summarizes the results of the Town of Cortlandville’s stormwater inspection program for 2022. Facilities included in the program are identified in Table 1 and Figures 1A (northwest), 1B (southwest) and 1C (east). The inspection program has two primary components. The first component is an annual self-reporting program in which all facility owners or managers provide information on inspections and maintenance they have performed during the past year (Section 2 3). The second component consists of inspections conducted by the SWCD of approximately one-third of the stormwater systems each year, such that each system receives an independent inspection approximately every three years (Section 4). Integrating self-reporting and SWCD inspection information, the SWCD provides facility- specific recommendations for the improvement of individual facility performance as necessary (Section 5) and a summary and recommendations regarding the effectiveness of the Cortlandville stormwater program as a whole (Section 6). 3. Self-Reporting In order to obtain information provided by the facilities themselves, a one-page self-reporting form is sent out by the SWCD annually to all owners or managers. Specifically, the self- reporting form asks for information regarding: • stormwater system functioning, • maintenance activities completed, • problems that have been identified, and • corrective actions taken to address identified problems. In spring, 2023, SWCD mailed letters to owners requesting that they complete and return self- inspection reports for 2022 facility performance. Non-respondents were pursued via multiple follow-up phone calls and emails. Ultimately, 45 responses (90% returned; Table 2) were received for 2022 reporting. Most facilities responding reported that their stormwater systems were functioning properly and no significant problems were identified (Table 2). Most reported that they inspected their stormwater facilities at least once in 2022; inspection was often associated with maintenance activities such as mowing or after significant storm events. Of the facilities reporting that they did inspect their facilities, inspection frequency varied from once per year to weekly. Regular maintenance typically included mowing of basins and swales and removal of debris from structures and basins. Several facilities reported that they hire professional stormwater inspection contractors to inspect and maintain their facilities, generally those with proprietary stormwater treatment components. Several facilities reported that no inspections and/or maintenance had occurred during 2022. SWCD will contact these facilities to improve communication, insure that they understand their maintenance responsibilities, and increase inspection oversight by the facility in future. Several facilities reported that they completed repairs to their storage or catch basins during 2022. Several properties did not self-report in 2022, several of which have been unresponsive in past years (Tables 2, 3). In spite of considerable effort to contact these facilities in 2022/2023, SWCD was unsuccessful in obtaining completed self-inspection forms from these facilities. 3 4. SWCD Inspections The SWCD conducted 16 inspections in 2022 (Table 1, highlighted; Table 4). These facilities were selected because they were due for inspection based on the established inspection rotation schedule or because they were newly constructed facilities that had not previously been inspected. Personnel for all facilities inspected in 2022 were contacted prior to the inspection and invited to be present. Many facility representatives chose to attend the inspection. Inspection protocols included examination of project design specification sheets and other SWPPP documentation and field inspection of stormwater facility components including the collection system, catch basins, swales, infiltration basins, proprietary systems and dry wells. Most of the stormwater systems inspected appeared to be functioning properly and most are being adequately maintained and/or repaired (Table 4). Detailed facility-specific inspection reports including recommendations for maintenance and/or enforcement to improve facility performance, as needed, are provided in Appendix A. Results of the individual inspections by SWCD (included in Appendix A) were provided to facility representatives by the SWCD following Cortlandville approval. In addition, the SWCD will remain available to provide technical assistance and guidance to facility owners and managers to ensure adequate maintenance and operation of these facilities. 5. Summary of Ongoing Facility Challenges Multi-year performance challenges have been identified that should be remediated through communication with property owners. The most common types of non-compliance are 1) chronic failure to submit annual facility self-inspection reports, 2) stormwater facility lacking or originally not constructed according to approved design and 3) required stormwater facility maintenance not being performed. Properties that appear to have no facilities or facilities that appear to be inconsistent with approved design plans, or that appear to require significant maintenance are listed in Table 5. 6. Conclusions and Recommendations Information provided through the self-reporting portion of the program indicates that: • the stormwater facilities are generally functioning properly, • inspections and maintenance are being routinely performed at most facilities, and • owners who do identify problems are taking steps to correct them. We recommend continued annual self-reporting by facility owners or managers. For 2023 activities, self-reporting forms will be sent by the SWCD to facility owners or managers in spring, 2024. 4 The majority of facilities inspected by the SWCD appeared to be functioning well and require no or modest maintenance as identified in the SWCD inspection. Several facilities highlighted in Table 4 require significant maintenance to improve system performance to an acceptable level. Additional information is provided in Appendix A for all facilities inspected by the SWCD. SWCD will perform the following actions in 2023 to address apparent issues: 1. Contact facilities for which no ongoing inspections by the facility were reported (Table 2), 2. Contact facilities that did not submit self-inspection reports for 2022, and 3. Conduct wet-weather inspections of the facilities indicated in Table 5. We recommend that stormwater facilities on properties identified in Table 5 that appear to have performance issues be addressed in the near future. These facilities may not be constructed consistent with project designs, may not be performing adequately, or require significant maintenance. Some facility owners/managers have limited knowledge of their stormwater facilities and maintenance requirements. In addition, in some cases the personnel responsible for the maintenance of the stormwater facilities changes frequently and establishment of a rapport with new staff is important, to provide information about the Cortlandville ordinance and the maintenance requirements for the facility. Inspections by the Cortland County SWCD provide an important and effective opportunity to convey this information to owners and facility managers. Printed information including system description and maintenance requirements were often provided by the SWCD to facility personnel present at the inspections. We believe this interaction will maintain current levels of facility maintenance and ordinance compliance. 5 Table 1. Facilities included in the Cortlandville Stormwater Management Program.

Collection System1 Stormwater Management System2 Maintenance Required Other/Notes 9 CNY Farm Supply Most of the grassed swale was well vegetated and dry. The lower portion was muddy and damaged by vehicle ruts A tanker truck was parked in the small infiltration basin behind the warehouse building. Some of the original infiltration basin no longer exists due to building construction. The remaining basin was dry and appeared to be infiltrating effectively Restore drainage grade of swale. Keep vehicles out of stormwater facilities A fifth storage building has been constructed on the property since the previous SWCD inspection. This property originally had significant pervious area but is now largely built out. Other than pervious grassed areas, the property has limited to no stormwater management and most stormwater appears to leave the property. Review by PE, Cortlandville recommended. See Table 5. 20 Fastenal Well-vegetated and maintained, appears to be functioning properly Well-vegetated and maintained, appears to be functioning properly Add additional rock to spillway between sand filter and infiltration basin. None at this time 22 McLean Road Storage All catch basins contained some sediments and some contained water. However, all appeared to be functioning properly. One dry well manhole could not be located and is likely buried under asphalt. Infiltration basins were well-vegetated and dry with no woody vegetation Remove asphalt and locate dry well. Stormwater facilities had been neglected and were in poor repair during an SWCD drive-by inspection in 2018. They have received considerable maintenance since that time. 24 Clark-Lowell DMD Generally well-vegetated and maintained, appears to be functioning properly Originally designed as a pond but does not hold water. Appears to work effectively as an infiltration basin Minor, see Appendix None at this time 25 Lowes Appears to be functioning properly. Some woodchuck damage evident. Both gates to wetland/infiltration areas damaged/standing open. Clean blocked catch basin grates and infiltration basin inlets. Control woodchucks to avoid additional damage. Remove/treat invasive purple loosestrife. Secure pond/infiltration areas. 26 College Suites at Cortland Catch basin sumps were very full of silt and grit. Some had sediments within 1-4" of pipe outlet inverts. Swales were well- vegetated. Gate valves in open position, they should be closed to function as ponds as designed. Basin embankments and spillways lacked maintenance; woody vegetation was present in these areas. Catch basins should be cleaned because sediment depth in many exceeded one-third total sump depth. Mow or otherwise manage vegetation of basins, forebays and spillways to prevent establishment of woody vegetation. See minor recommendations in Appendix A. See Table 5. Consider review by PE and by Cortlandville to determine consistency with Town ordinance. 27 Walmart Generally well-maintained, appears to be functioning properly. Several catch basins require cleaning Appears to be functioning properly Minor, see Appendix None at this time 28 Intertek All catch basins contained some sediment and water but not to an extent that performance should be affected. Outlet structure dry and relatively clean. Central catch basin constructed below grade such that treatment of some flow appears to be bypassed Well-vegetated and maintained. Appears to be functioning properly Address small rill area just below central catch basin Consult with original system designer to evaluate significance of central catch basin rim elevation on treatment adequacy 30 Family Health Network Catch basins undesirably full of sediment Dry wells contained some fine sediment and pine needles; one contained street trash. System appears to be functioning properly Reseed and revegetate bare areas in south bioretention area. Catch basins should be cleaned out. See Appendix A None at this time 1 Swales, ditches, pipes and overland flow that conveys runoff to stormwater management structures 2 Basins, outlet structures and other features that manage runoff for quantity and quality control Inspection Observations RecommendationsSWCD ID Property Name 15 Table 4 (continued). Summary of 2022 inspections performed by SWCD for the Town of Cortlandville Stormwater Maintenance Program. Collection System1 Stormwater Management System2 Maintenance Required Other 31 KFC Catch basins undesirably full of sediment and debris Infiltration basin contained wetland and woody vegetation and does not appear to empty fully between storms. Proprietary CrystalStream system contained well more sediment than recommended. CrystalStream system requires inspection and cleaning. Infiltration basin should be cleared of woody vegetation and mowed annually. Catch basins should be cleaned out. See Appendix A Infiltration basin may require rehabilitation in future to restore infiltrating properties and capacity 33 Empire Tractor Some swale areas appeared to be draining poorly or disconnected from the stormwater system. Some sections of swales lacked vegetation. Most areas well vegetated Well-vegetated and maintained, appears to be functioning properly Observe swales to evaluate drainage; revegetate bare areas SWCD will observe wet weather performance in 2023. 34 Redding Reloading Equipment Unclear whether basins containing dry wells are graded to receive all stormwater. See Table 5 One portion of the pavement appears to drain south to Starr Road rather than north to the stormwater system inconsistent with the original design. See Table 5 None at this time Consider consulting with original system designer to evaluate drainage toward Starr Road and dry wells. SWCD will continue to observe wet weather performance. 35 Squeaky Clean All catch basins were more than 33% full of fine sediments Southern two dry wells were dry indicating they empty between storms; the third contained some water. The facility was in use at the time of inspection so some water in dry wells is to be expected. All catch basins need to be cleaned as they contain sediment beyond recommended depths. See minor recommendations in Appendix A 36/36B Cortland Commerce Retail Center/ McDonald's All catch basins were reasonably clean. A small erosional area was observed on the west side of the property draining into the western infiltration basin. The eastern forebays was not draining well, was ponded and contained wetland vegetation. It is not draining between storms as desired. However, no problems were observed. The western forebay was dry but contained wetland vegetation. Infiltration basins were dry and appeared to be functioning normally. Erosional area should be revegetated or rocked to prevent future erosion. See minor recommendations in Appendix A 39 Tractor Supply Store All areas were well-vegetated and maintained Large infiltration basin has been significantly renovated since the 2019 SWCD inspection. Basin was dry with ~no woody vegetation and appeared to be working properly. Spillway had some significant bare spots. Revegetate bare areas on spillway See minor recommendations in Appendix A (Note: facility reports that recommended actions were completed 3/29/23) 56 Gutchess Sports Complex Phase 1 Most areas were well-vegetated and maintained. Bioretention areas, swales and areas around drywell inlets contained numerous small bare soil areas. Area around the new restroom building was very poorly vegetated. New parking areas were apparent that are not in design materials and do not appear to have associated stormwater facilities. Three of the nine dry wells contained water indicating slow infiltration. This may be a function of sedimentation during construction and may not affect long-term performance. Bare areas should be reseeded and mulched. Area around the new bathroom building should be revegetated as initial vegetative cover is inadequate. Dry wells containing water should be observed by property manager to ensure adequate function over time. Stormwater facility needs in new parking areas should be evaluated by a design professional.

Review of system by PE 8 Doug's Fish Fry 2021 During the SWCD 2021 dry weather inspection it was observed that two dry wells contained significant water/oil & appeared clogged. The fryer oil disposal bin may be contributing significant oil to the system. Clean and renovate dry wells #1 & #2.Waste oil containment should be considered. The 2021 SWCD dry weather inspection indicated that one dry well is either clogged or draining slowly and appeared to contain an oil water emulsion with fine sediments. During a 10-26-22 wet weather inspection, several inches of stormwater were standing on this dry well. It needs to be fully renovated to restore function and all waste oil should be separated completely from the stormwater drainage system. In the 2022 Self- Inspection Report, maintenance including dry well pumpout and sediment cleanout is reported. Clean and renovate dry wells #1 & #2.Waste oil containment should be considered. The 2021 SWCD dry weather inspection indicated that one dry well is either clogged or draining slowly and appeared to contain an oil water emulsion with fine sediments. SWCD 2022: performance adequacy of the dry wells is unknown. SWCD will observe wet weather performance in 2023. 9 CNY Farm Supply 2019 New impervious surface constructed without required stormwater facilities; some existing stormwater facilities reduced in size or removed altogether. Review by PE During a 10-26-22 SWCD wet weather inspection it was observed that another storage building had been constructed on the property since our previous inspection. This property originally had significant pervious area but is now largely built out. Other than pervious grassed areas, the property has limited to no stormwater management and most stormwater leaves the property. SWCD 2022 Inspection: Construction of an additional building and apparent inadequate stormwater facilities confirmed. Review by PE, Cortlandville compliance status review 11 Cortland Self Storage 2018 No collection system exists on the site; significance unclear Review by PE During a 10-26-22 wet weather inspection indicated standing water throughout the property. However, considerable area is available for infiltration downgradient of impervious surfaces and it was unclear whether water was leaving the property and affecting downgradient landowners. Consider review by PE 26 College Suites at Cortland 2019 Pond gate valves in open position, they should be closed Close both gate valves to hold water and function as designed During a 10-26-22 wet weather inspection, both basins contained some water, little water was present onsite generally (indicating effective infiltration) and no issues were observed. During the routine 2022 SWCD inspection (7/13/22) it was observed that the ponds are continuing to be operated as infiltration basins/forebays rather than stormwater ponds. SWCD 2022 Inspection: Gate valves remain in open position. Many catch basins require cleaning. Basins contained some woody vegetation. Consider review by PE and by Cortlandville to determine consistency with Town ordinance. Facility requires maintenance. 28 Intertek 2019 Central catch basin constructed below grade, some parking lot runoff may not be receiving treatment Review by PE Review by PE 34 Redding Reloading Equipment 2019 Appears inconsistent with original design. One portion of pavement appears to drain to Starr Road rather than to the stormwater system Review by PE During a 10-26-22 wet weather inspection, it did appear that the front of the property was draining to Starr Road but the volume appeared to be minimal and no flooding or standing water was observed in the vicinity. SWCD 2022 inspection: it was unclear whether either dry well was in an effective basin that accumulated stormwater flow. It appeared that at least some flow may be bypassing the basins containing the dry wells and draining on to private property to the west/northwest. Consider review by PE. SWCD will continue to observe wet weather performance. 43 Royal Chevrolet 2020 New asphalt pad constructed in infiltration gravel strip, may also be blocking some draining to strip Review by PE Review by PE 45 Smith Allergy & Asthma 2017, 2020 Runoff appears to drain to adjacent property rather than to property's stormwater facilities Review by PE During a 10-26-22 wet weather inspection stormwater on the Smith property in this area entered a grassed depression that was not draining to either the adjacent property or the Smith stormwater facility. Instead, it appeared to be adequately infiltrating the relatively small drainage area (volume) upgradient. Very little water was observed on either property. SWCD should continue to observe wet weather performance. 48 Splash Car Wash 2021 Spillway weir did not appear to have been installed; no division between forebay and infiltration basin was apparent. Clean both inlets since >33% full. Assess by PE Clean both inlets since >33% full. Assess by PE 56 Gutchess Sports Complex Phase 1 2022 Considerable bare soil was present especially around new bathroom building and new parking area. Small bare areas were also present around many dry wells; sediment from these areas could reduce infiltrating ability of the dry wells. New parking area was not described in SWPPP documents in SWCD files. Seed and mulch all bare areas. Update SWPPP materials to ensure compliance with regulations. 1 Facilities in gray were inspected by the SWCD in 2022; inspection reports are in Appendix A 2 2022 updates indicated in pink 17 SWCD ID Facility Name Page 9 CNY Farm Supply A-1 20 Fastenal A-7 22 McLean Road Storage A-12 24 Clark-Lowell DMD A-18 25 Lowes A-22 26 College Suites at Cortland A-30 27 WalMart A-38 28 Intertek A-44 30 Family Health Network A-49 31 KFC A-55 33 Empire Tractor A-62 34 Redding Reloading Equipment A-67 35 Squeaky Clean A-72 36/36B Cortland Commerce Retail Center/McDonalds A-78 39 Tractor Supply Store A-84 56 Gutchess Sports Complex Phase 1 A-89 Appendix A SWCD Inspection Reports A-1 Stormwater Inspection Report 9 CNY Farm Supply Owner: David W. Law Facility Address: 3865, 3871 Route 11 Date Inspected: 7/13/22 Inspected by: K. McGrath Overview The original facilities were designed by Resource Associates as described in the SWPPP dated September 11, 2002. The facility was originally called CNY Power Sports. The stormwater system was designed under less stringent design criteria before the State’s Phase 2 stormwater regulations became effective. The proposed system was to consist of two detention basins that would receive runoff by overland flow. The basins were to be located on either side of the CNY Power Sports building to the east and west. The west detention basin was constructed and receives most of the runoff from the site. The outlet to the basin is located at the south end. The main outlet is a 12-inch diameter pipe raised 6 inches above the bottom of the basin. There is also a 6-foot wide grassed overflow to allow for high flows. Because the basin is large and shallow, it may not be obvious to the casual observer. The basin discharges to the south to the ditch parallel to the railroad tracks. The east basin was never built. It was designed to have a 10-inch diameter outlet pipe raised 6 inches above the bottom of the basin, with a 3-foot wide grassed overflow to allow for high flows. The outlet pipe to the basin was to be located at the southwest end of the basin and the basin was to have discharged to the ditch parallel to the railroad tracks. In 2017, an additional SWPPP was prepared by Resource Associates to address the proposed construction of two storage buildings and a warehouse building on the southwest corner of the property and to acknowledge the previous addition of two smaller self-storage buildings within the detention basin. A new pretreatment grass swale was proposed to be added to the existing detention basin and some of the runoff was proposed to be routed to an existing onsite pond. Observations Little has changed on the site since the 2019 SWCD inspection except that a fifth storage building has been built in line with the existing four storage buildings. Most of the property has been built out with impervious surfaces of gravel, pavement and roofs. The original infiltration basin and grassed swale still exist between the new warehouse building and the first (easternmost) storage building and behind the new warehouse building. The infiltration basin and upper portion of the grassed swale were dry. The lower portion of the grassed swale was muddy and had large vehicle ruts running across it. Wetland vegetation including sedges was A-2 established in the area indicating frequent and prolonged wetness. A tanker truck was parked in the small infiltration basin area behind the warehouse building. The slope to the adjacent downgradient property to the east from the main building parking lot has been rocked for stabilization during stormwater discharge. However, the rock has failed and deep rilling is present on slope. No grassed swale as proposed in 2017 was observed along the back (south) of the storage unit buildings. All five of the storage unit buildings as well as the large storage warehouse for the CNY Power Sports business have now been built out. Stormwater from the five storage buildings drains south to the SuitKote ponds without treatment. Multiple locations of rill erosion were observed along the slope above the railroad tracks to the south indicating significant uncontrolled stormwater discharge from this area. Recommendations The lower end of the swale and associated small lower basin should be renovated to restore infiltrating ability. These facilities should be managed with care to ensure functionality. This includes keeping vehicles out of them at all times. Considering the progressive construction of additional buildings and gravel roadways without construction of proposed stormwater facilities, this property does not appear to meet the requirements of the Cortlandville ordinance for water quality and quantity treatment. We recommend that Cortlandville personnel review the proposed and as-built drawings to determine whether building and stormwater construction has occurred consistent with Town approvals.

A-7 Stormwater Inspection Report 20 Fastenal Owner: Compagni Land Development LLC Facility Address: 3737 Luker Rd Date Inspected: 7/12/22 Inspected by: K. McGrath Overview The stormwater facilities were designed by Resource Associates and as described in the May 15, 2006 SWPPP and associated drawings. The stormwater system is comprised of swales, a water quality treatment basin, an infiltration basin and a dry well. Grass swales run along the north and south sides of the building, carrying runoff eastward to the water quality basin and then on to the infiltration basin/dry well complex. The northern swale carries bypass flows upgradient of the property directly to the road ditch and the southern swale carries stormwater from the property to the treatment complex. The southern swale has a 12-inch culvert to convey runoff beneath the parking area entrance into the treatment complex. Flow enters from the southern swale into the sand filter basin and flows into the infiltration basin via rocked spillway. Flow enters the dry well subsurface from the infiltration basin. Excess stormwater leaves the infiltration basin via a rocked spillway to the adjacent road ditch. The water quality basin is a sand filter. The base of the sand filter consists of a 4-inch layer of pea gravel, overlaying filter fabric, overlaying a 24-inch thick layer of filter sand, overlaying an 8-inch layer of #2 stone, overlaying an impermeable layer. Two 6-inch diameter perforated drains are located in the bottom gravel layer of the water quality basin. The perforated drains connect to a dry well in the infiltration basin. The infiltration basin has a 3-foot wide infiltration trench with a 4-inch layer of rounded stone at the surface, overlying filter fabric, which overlies a 4-inch layer of concrete sand, which overlies a 5-foot layer of #2 and #3 stone. The sides and bottom of the trench are wrapped in filter fabric. The dry well in the infiltration basin has a 12-inch diameter discharge pipe that connects to the Town of Cortlandville’s ditch on Luker Road. Observations The site appeared to be constructed as designed. The entire site was well-vegetated and mowed with minimal debris present and no woody vegetation. Minimal erosion was evident; small patches of bare soil were seen in the southern swale near the entrance to the sand filter. The infiltration and water quality basin were free from sediment or other debris. Small amounts of gravel were seen in the sand filter, likely from a rocked slope below the A-8 parking area. A small volume of street trash was present in the dry well but is unlikely to be affecting performance. Rock riprap was missing from one area of the spillway between the sand filter and the infiltration basin. Recommendations Street trash present in the dry well appears to be coming from the road ditch, indicating that at high flows, the road ditch drains into the dry well. Contributions of trash and sediment into the dry well from the road ditch will reduce viable life of the dry well before maintenance/renovation is required. We recommend that the design professional examine the dry well outlet pipe grade to determine direction of flow during high water and to assess potential impacts on the dry well. Additional rock should be added to the spillway between the sand filter and the infiltration basin. A dense stand of grass should be maintained on all swales and basin sideslopes to minimize sedimentation and protect the sand filter, infiltration basin and dry well; bare areas should be revegetated. No additional recommendations at this time.

McGrath Overview The original facilities were designed by Resource Associates as described in the SWPPP dated October 10, 2006. The stormwater system is comprised of three settling tank/dry well units and two infiltration basins. The settling tank/dry well complexes are located at the south end of the storage units (front of property along road), at the north end (back) of the storage units and on the east side of the units. Per settling tank/ dry well unit, runoff enters the settling tank via a grate at the surface, graded so runoff flows overland to the grate. Each settling tank is connected to a dry well by a 3-inch diameter low level pipe and a 6-inch diameter high level pipe located about 3.7 feet above the floor of the tank. A baffle in the settling tank chamber controls flow to the dry well, and is intended to minimize velocity and allow for sediment to settle out before reaching the dry well. The baffle is designed to maintain a minimum water depth of 8 inches within the tank. Low flows are controlled through two 2-inch diameter orifices near the base of the structure, moderate flows pass through a 4-inch orifice located approximately 2.4 feet above the base of the tank and higher flows pass over the baffle system as weir flow. The infiltration basins are located adjacent to the new parking lot located in the northwest corner of the site behind the office building. These grass-lined basins were designed to be 2 feet deep and have 4 inches of topsoil installed before seeding. For drainage purposes, the design called for a 1- foot wide by 1.5-foot deep stone trench filled with #2 stone located below the topsoil layer. Observations Both infiltration basins were well vegetated and dry, with no debris or woody vegetation. There was no evidence of long-term water retention and both appeared to be functioning properly. The dry well manhole cover of the back settling basin/dry well complex could not be located and appeared to be buried under asphalt. The settling basin contained several inches of water and 2” of fine sediments. Of the easternmost complex, the settling basin contained 3-4” of water and 3-4” of fine sediments and the dry well was dry with 1-2” of fine sediments. Of the front (southern) pair, both the settling basin and the dry well were dry with 3-4” of fine sediments. All appeared to be functioning properly. A-13 Recommendations In order to verify condition and performance of the back dry well, the manhole should be located and unburied. No other recommendations at this time.

A-18 Stormwater Inspection Report 24 Clark-Lowell DMD Owner: Lowell Properties LLC Local Address: 3773 Luker Rd Date Inspected: 7/11/22 Inspected by: K. McGrath Description of Stormwater Facilities The stormwater facilities were designed by Timothy Buhl, P.E. as described in the April 2008 SWPPP and associated design documents. The stormwater system was designed as a forebay and stormwater pond, with a ditch swale to convey runoff to the pond. There is also a diversion ditch that carries runoff from upstream (offsite) areas around and past the site. See attached figure. The site is graded to direct runoff to the ditch that runs along the southwestern property line. The ditch conveys flow to a 15-inch diameter culvert beneath the driveway to a forebay leading to the stormwater pond, located adjacent to Luker Rd. The pond design called for an impermeable liner to maintain a permanent pool of water. The permanent pool was designed to be about 4 feet above the base of the pond. Flow from the pond is to a manhole outlet structure. Low flow is through a 4-inch diameter pipe to the outlet structure. Higher flows pass through a 6-inch diameter orifice in the side of the manhole outlet structure. Flow from the outlet structure is though a 12-inch diameter pipe to the Town’s drainage ditch on Luker Road. A diversion ditch runs along the northeast property line, leading from the sloped area in the back of the property to the Town’s drainage ditch on Luker Rd. This runoff bypasses the stormwater pond. Observations The basin was originally designed as pond, but because it does not hold water, it serves more as an infiltration basin. As an infiltration basin it appears to be effective and because a forebay is also part of the facility, water quality and quantity appear to be handled adequately. The swales on each side of the property were generally well-vegetated and mowed with no evidence of erosion or wetland vegetation that would indicate long-term standing water. The forebay and infiltration basin were also generally well-vegetated and mowed with no evidence of long-term standing water. A small patch of bare soil was observed on the west side of the forebay. Both basins were dry with no wetland vegetation. No debris was observed in either the forebay or basin. The spillway between the forebay and infiltration basin was well rocked with no woody vegetation. A-19 Maintenance appeared to be generally adequate and effective. Recommendations Bare areas should be revegetated. No additional recommendations at this time.

McGrath Overview The stormwater facilities were designed by Costich Engineering as described in the March 2008 SWPPP and associated design documents. The stormwater system consists of a collection system and detention pond. The detention pond is located at the northeast corner of the property. The west end of the pond is a forebay of sorts which receives the initial runoff from the site, and where settling of sediment can occur. From the forebay, water moves east to the main part of the pond. The pond has an impermeable liner to maintain a permanent pool and to prevent water from infiltrating to groundwater. The design called for waning tape to be placed along the top of the liner, presumably to prevent damage to the liner during maintenance. The outlet to the pond is at its east end. The outlet structure is a 2-feet square manhole-type structure with a low level orifice inlet located about 1.5 feet below the top of the structure and about 5 feet above the bottom of the pond. High flows enter the structure through a grate at the top. The outlet to the outlet structure is a 12-inch diameter culvert that leads to Otter Creek. There are two main runoff collection areas. Runoff from the impervious surfaces at the front of the building is captured in catch basins and conveyed to the forebay of the detention pond by storm drains, ranging in size from 15 to 36 inches in diameter. Runoff from the roof and from the back of the building is collected in a detention basin at the rear of the building. The detention basin also has an impermeable liner to prevent infiltration to groundwater, but does not maintain a permanent pool of water. A 30-inch diameter outlet pipe conveys runoff from the detention basin to the forebay of the detention pond. Observations Grass swales draining the western portion of the property were well mowed and maintained. The southern swale inlet had considerable organic material that was partially blocking flow. The forebay and detention pond were well vegetated with herbaceous plants and grasses and well- mowed; no woody vegetation was observed. Open water was present in both the forebay and the pond. In general the vegetation was in good condition. The pond was providing ecological value in that many frogs and other organisms were observed. The water level in the pond was high in spite of the dry weather; water was backed up into the west inlet pipe and may be slowing drainage of some A-23 asphalt areas. Purple loosestrife, an aquatic invasive species, was present around much of the pond margin. The spillway and inlets were rocked as designed. There was one woodchuck hole immediately adjacent to the spillway control structure. The access gate was unlocked and standing open, and damaged. All catch basins that could be accessed were inspected. Catch basins contained zero to 4” of water and all were clean and clear of debris and sediment. However, all catch basin grates along the back (east) of the property were partially blocked with leaves and trash. One catch basin could not be located because it was buried under a row of shopping carts. The loading dock trench drain covers were in poor repair and the drain was largely filled with organic material and grit. The detention basin along the back of the building was well vegetated and dry and contained no trash or other debris. A small quantity of sumac (woody vegetation) was observed as well as purple loosestrife. The access gate to this facility was also standing open at the time of the inspection. Recommendations Infiltration swale inlets should be cleared of all debris. Mowing annually of grassed areas and detention basin side slopes to remove woody species should be continued. All vegetative debris should be disposed of outside the retention facilities to maximize performance and reduce maintenance frequency of these facilities. Catch basin grates at the back of the building should be cleared of organic material and trash to reduce the load of organic material entering the detention basin. Accessibility of these grates should be restored. All catch basins should be cleaned when sediment deposit depth in the sump is greater than or equal to one-third the depth from the basin invert to the lowest pipe or opening into or out of the catch basin. Purple loosestrife is a noxious invasive species and should be removed. Herbicides are available that will control this species. In addition, several beetle species have been identified that will control this species if released in the area. Woodchuck damage to the pond berms should be repaired and mammal populations controlled to avoid compromising the pond dam/berm. Gates should be repaired so that detention basins are protected and to ensure the public’s safety. The trench drain should be repaired and cleaned.

A-30 Stormwater Inspection Report 26 College Suites at Cortland Owner: UC Cortland Housing LLC Facility Address: 951 Route 13 Date Inspected: 7/13/2022 Inspected by: K. McGrath Overview The stormwater facilities were designed by Timothy C. Buhl, P.E. as described in the February 2008 SWPPP and associated design documents. There are two main stormwater systems and a minor third system. The two main systems each consist of a collection system that conveys runoff to a retention pond. The minor system, a rain garden, receives runoff from a relatively small drainage area. One main system manages runoff for the building and parking lots on the west side of Otter Creek. The retention pond for this system is located northeast of the west-side building. The other main system manages runoff from the building and parking lots located east of Otter Creek, with the retention pond located directly west of the east-side building. The two main systems have similar designs. Each has a collection system of catch basins and storm drains that convey runoff to a retention pond. Each retention pond has one or more forebays that provide water quality pretreatment prior to flowing into the retention pond. These retention ponds are design to have a permanent pool, with a maximum normal water depth of about 4 feet. Each was designed to have an impermeable liner to maintain the permanent pool. The outlet to each retention pond is a 4-foot diameter manhole structure. For each, the low level outlet from the pond to the structure is a 4-inch diameter pipe with an end cap, and a 2.5-inch hole in the end cap. Under high flow, water enters the structures thought a grate at the top. The outlets from the outlet structures are 15-inch diameter pipes that flow to Otter Creek. Each retention pond also was designed to have a means of draining the ponds for maintenance. Each pond has an 8-inch diameter pipe extending from the base of the pond to the base of the manhole outlet structure. A gate valve at the end of the pipe prevents flow, until maintenance is required. Both ponds were designed to be lined and to hold water with valves in the closed position except when periodic maintenance is required. It is unclear whether the ponds were lined during construction and whether they were installed as ponds or infiltration basins. The ponds have for at least are being managed as infiltration basins rather than ponds. Neither had any water at the time of inspection and both valves appeared to be fully or partially in the “open” position. The minor system (rain garden) is located at the north corner of the property. It collects runoff from the north driveway entrance area. The rain garden is a grass-lined depression with a 2-foot wide trench drain that has a 2.5-foot thick sand filter above a 4-inch diameter perforated drain encased in A-31 gravel. The trench drain is wrapped in filter fabric. The perforated drain has an outlet to Otter Creek. Observations Catch basin drainage routing is not as indicated on design sheets provided to the SWCD. They have been updated as indicated on the diagram below. Drainage to the southern forebay of the northern pond is not via catch basins but by surface flow across the parking lot and into the forebay via curb cuts. All catch basins were observed and photographed. Distance from pipe inverts to sediment surface ranged from 2 to 6”. Fine sediments, pine needles and other organic material were observed in the catch basins. This is undesirable as this material can increase maintenance requirements of receiving stormwater management facilities. Grassed areas were generally in good condition and were well mowed. The southern pond had not been maintained and woody vegetation was observed in the basins, side slopes and spillway. The spillway to Otter Creek was covered in vegetation including woody vegetation and was not visible. Maintenance staff were actively cutting vegetation at the time of the inspection. The northern forebay/infiltration basin was better maintained and had been mowed recently. Woodchuck holes were observed on both banks of the infiltration basin in the southwest corner to the west of the outlet spillway. The raingarden was dry and was somewhat covered in weedy vegetation. It was for the most part vegetated with grass rather than typical rain garden species. It appeared that this facility would retain at least some water during rainfall events but whether performance meets Town requirements is not known. It does not hold water sufficiently to support wetland vegetation. The spillway and outlet pipe were covered in vegetation and were not visible. Recommendations The original design engineer or other design professional should be consulted to determine if current management of the rain garden and management of the ponds as forebay/infiltration basins meet the requirements of the Town ordinance. Otherwise, the pond valves should be left closed, the ponds should be allowed to fill as designed and wetland vegetation should be established within the basins. A-32 Some additional maintenance is recommended to improve long-term function of the stormwater facilities: 1. Woodchuck population control and repair of embankments 2.

A-38 Stormwater Inspection Report 27 WalMart Owner: WalMart Stores East, LP Facility Address: 819 Bennie Rd Date Inspected: 7/26/2022 Inspected by: K. McGrath Overview The stormwater facilities were designed by ADP Engineering as described in the May 20, 2008 SWPPP and associated design documents. The stormwater system consists of a collection system that conveys runoff to a retention pond. The collection system consists of catch basins that collect runoff from impervious areas, a grassed swale along the south side of the property and subsurface storm drains that convey runoff to the retention pond. The catch basins are equipped with hooded inlets that reduce the transport of floatable debris through the system. After water has settled in the retention pond for at least 24 hours, it is pumped to a gravity storm drain that feeds water to one of four subsurface infiltration beds along the northeast corner of the property. The infiltration galleries have valves that control which are in use at any given time. In 2021 SWCD staff addressed two questions at the request of a concerned citizen: 1) based on existing groundwater data, is there a need for additional monitoring, and 2) is WalMart managing their stormwater facilities consistent with SWPPP requirements? We examined groundwater data from 2009-2016 for metals, volatile organics, semi-volatile organics and conventional pollutants. No significant patterns in the data were observed over time or space and additional sampling did not appear to be justified at this time. The only parameter of concern was salt, which is not unusual and not unique to WalMart. We reviewed monthly stormwater management inspection forms provided by Wal Mart’s stormwater contractor and concluded that the property was being appropriately managed and use of the four infiltration galleries was rotated regularly as required. Additional detail regarding these assessments is available upon request. Observations A contractor inspects the site regularly on behalf of this company and performs maintenance and repairs as necessary. Use of infiltration galleries is rotated regularly. Site maintenance and inspection reports are provided to the SWCD as requested. Eighteen randomly selected catch basins were examined. Most contained 1-3” of grit and 4-14” of water and appeared to be functioning well. Most had floatables hoods. Several were found to contain excessive depths of silt or gravel (see figure below). One was clearly plugged with evidence of past standing water and silt deposition in the parking area. In two catch basins the hoods were not attached to the outlet properly and were not functional. A-39 The infiltration gallery area was well-vegetated with tall weeds but no woody vegetation was observed. The four gallery control valve areas were accessible and identified with signs. The retention pond was well-maintained. The side slopes were mowed and no erosional areas of significance were observed. Wetland vegetation primarily consisting of cattails and sedges were present on the north and south sides of the pond. Recommendations Most catch basins were well-maintained and appeared to be functioning properly. Several as indicated above (and see figure below) require maintenance. Regular inspections and maintenance of the stormwater system should be continued. No other recommendations are provided at this time.

A-44 Stormwater Inspection Report 28 Intertek Owner: Electrical Testing Labs Inc Facility Address: 3933 Route 11 Date Inspected: 8/8/2022 Inspected by: K. McGrath Overview Stormwater facilities were designed by Resource Associates as described in the August 2008 SWPPP and associated design documents. The stormwater system was designed to manage runoff from an expansion to the pre-existing Intertek site. The expansion consisted of a new pole barn, an expansion to an existing pole barn, and an expansion of a driveway parking area. The system was not intended to manage runoff from the pre-existing developed areas. The stormwater system basically consists of a stormwater collection system, two settling basins, and a water quality filter system. There are two structures that serve as catch basins to collect runoff from the paved areas and roof drains, and they also serve as flow control structures, as described below. Although the central catch basin was designed and built 0.5” below grade, it does not appear that it should have been intended to receive surface flow, as it is designed only to merge excess flows from the northern and eastern catch basins for routing to the River outlet. As such some portion of the asphalt area appears to discharge to the river without any water quality treatment. Low Flow Conditions – Roof runoff enters the northern and eastern catch basins and flows to the 2 settling basins. Surface water runoff enters the adjacent settling basins directly through sheet flow. The settling basins have outlet structures with a vertical riser pipe with holes to control outflow. Runoff then flows to the water quality treatment filter located between the settling basins. The filter is a basin with 4 inches of gravel at the surface, 12 inches of concrete sand filter media below that, and a 6-inch diameter perforated underdrain system encased in #1 and #2 stone below that. The underdrain piping is tied into the outfall to the Tioughnioga River at a central manhole located in the filter area. High Flow Conditions - The catch basins leading to the settling basins also serve as diversion structures. When the northern and eastern catch basin outflows exceed inflow, excess is diverted to the central catch basin and then to the central manhole and is discharged, untreated, to the river. Observations It appears that although installed as designed, some direct asphalt drainage is able to enter the central catch basin and discharge directly to the Tioughnioga River via the outlet structure. In addition, a small rill area immediately adjacent to the central catch basin drains some stormwater from the A-45 parking area directly to the water quality treatment basin. Although this rill area does discharge some sediment to the water quality treatment area the quantity is minor and is not likely to affect infiltration or treatment capability of this basin. Because this basin does treat stormwater before discharge, this erosional area is treated prior to discharge to the river. Settling basins and the water quality treatment basin were well maintained through mowing; no woody vegetation was present. No problems were observed and this portion of the system appeared to be operating effectively. The north and southeastern catch basins contained 30-32” of water and 1-2” of sediment deposits, and the central catch basin contained 6” of water and 1” of sediment. These sediment quantities should not be of sufficient depth to affect performance. The outlet structure was dry and relatively clean. Recommendations The original design professional or some other stormwater design professional should be consulted to evaluate the routing of stormwater to the three catch basins relative to effective water quality treatment. The erosional area adjacent to the central catch basin should be regraded and revegetated. All catch basins should be cleaned when sediment deposit depth in the sump is greater than or equal to one-third the depth from the basin invert to the lowest pipe or opening into or out of the catch basin.

A-49 Stormwater Inspection Report 30 Family Health Network Owner: McNeil Development LLC Facility Address: 4038 Route 281 Date Inspected: 7/15/2022 Inspected by: K. McGrath Overview The stormwater facilities were designed by McNeil Development LLC (Thomas Farlow, P.E.) as described in the October 2009 SWPPP and associated design documents. The stormwater system is comprised of 2 bioretention areas with associated dry wells, one in the southwest corner of the property and one along the southern property line draining to the southeast. In the southeast corner, and additional bioretention area was originally proposed but was either never constructed or has been modified since construction. A catch basin in the northeast corner of the property and roof leaders drain to two dry wells in the parking area in the northeast corner of the property. All dry wells are 6 feet 8 inches in diameter. The bioretention areas are grass-lined depressions or swales with 6 inches of topsoil, overlying 8 inches of filter sand that provides water quality treatment, overlying a 6-inch diameter perforated underdrain encased in #1 stone fill. The underdrains are connected to an associated dry well. One bioretention area is located at the western end of the property adjacent to Rt 281 (note that a part of this system is in the NSDOT right of way). Runoff reaches this by overland flow and through a catch basin located in the parking lot. There is a dry well located in the southeast corner of the bioretention area. The top of the dry well is about 3.5 feet above the base of the bioretention area, and has a 24” by 24” grate. Under low to moderate flow conditions, treated runoff either infiltrates to groundwater or flows to the dry well via the underdrain system. Under high flow conditions, water can enter the dry well through the top grate. The other bioretention area is along Crestwood Court and is separated by the eastern driveway entrance. There is a stormwater inlet at its eastern end. The underdrain system connects to this storm inlet, and then passes to the drywell in the parking lot via a 20-inch diameter drain pipe. A grate at the top of the storm inlet allows high flows to pass directly to the dry well. Runoff from the roof and from a small section of parking lot flow to 2 dry wells located in the northeast part of the site. Roof runoff is connected to these dry wells by subsurface pipes. Parking lot runoff enters a catch basin at the east property line and flows to the southernmost of the 2 dry wells through a 12-inch storm drain. The two dry wells are connected by a 12-inch pipe. A-50 Observations Catch basins contained significant grit and fines and sediment was within 4” of pipe inverts. The southeast catch basin contained fine sediments that were supporting growth of vegetation within the catch basin. The southwest bioretention area was well vegetated and the dry well was clean and dry. The southern bioretention area had some significant bare spots with no or thin vegetation. In addition this bioretention area showed some bare areas devoid of vegetation that appeared to be due to standing water, suggesting limited infiltration in that area. The dry well infiltrating this area contained significant street trash. The dry wells in the northeast corner of the property were dry. They both contained a layer of organic material and pine needles. All dry wells appeared to be draining well. Recommendations The stormwater system generally appeared to be functioning well and was well-maintained. Bare spots and thin grass in the southern bioretention basin should be reseeded and mulched to restore adequate grass cover. This will reduce erosion and sedimentation of catch basins and dry wells and protect dry well functionality. Street trash should be removed from bioretention areas on a frequent basis to keep them out of catch basins and dry wells. When sediment deposit depth in a catch basin sump is greater than or equal to one-third the depth from the basin invert to the lowest pipe or opening into or out of the catch basin, the catch basin requires cleaning. All catch basins had less than one-third of their original sump capacity and therefore should be cleaned in the near future. In order to maximize function but as importantly, protect the longevity of bioretention basins and dry wells, the property should be managed to minimize delivery of organic material such as pine needles and grass clippings as well as street trash to these facilities.

A-55 Stormwater Inspection Report 31 KFC Owner: Cleary Oil, Inc. Facility Address: 3890 Route 281 Date Inspected: 7/15/2022 Inspected by: K. McGrath Overview Designed by M.V. Weiss and Associates as described in the August 2009 SWPPP and associated design documents. There are 3 main stormwater components: 1) Parking lot runoff is captured in catch basins along the north and south sides of the building. Storm drain pipes convey the runoff to a CrystalStream water quality vault located just west of the infiltration basin. After pre-treatment, runoff flows to the infiltration basin through an 18-inch diameter pipe. The grass-lined infiltration basin has a 2-foot thick layer of filter media composed of 2/3 topsoil and 1/3 concrete sand. There is no surface/overland outlet for this basin, and it is intended to drain between storm events. 2) Roof runoff is connected to a catch basin located east of the building. Runoff from the catch basin flows to a 7.5-foot diameter dry well. This dry well is connected to a second dry well by a 12-inch pipe in order to provide additional infiltration capacity. 3) Runoff from the lawn area along Rt. 281 is captured in a small grass lined infiltration basin. A 7.5-foot diameter dry well is located in the basin to provide additional infiltration capacity. The dry well has a grate to allow flow in through the top, but the top of the grate is elevated about 6 inches above the basin so that only larger flows pass through the grate. This promotes infiltration down through the grass and topsoil, and provides better water quality treatment. Observations Catch basins draining the asphalt drives contained significant sediment, primarily fine to coarse grit. The northwest catch basin was dry and was choked with an unknown depth of gravel above the level of the outlet pipe invert. The northeast, southeast and southwest catch basins contained significant sediments and grit as well. The CrystalStream water quality unit contained significant minor amounts of larger sized grit but sediments were 6” or more deep in one area. The unit contained significant water as well. The infiltration basin has no outlet and is designed to empty fully during rainfall events. The floor of the basin had wetland and woody vegetation indicating that is not draining between storms and frequent vegetation management is not occurring. The side slopes did not have woody vegetation indicating at least annual mowing. A-56 The two grassed areas with dry wells were well-maintained by mowing and no significant erosion or debris were observed. The dry wells draining these areas were clean and dry. The manhole and drywells draining the roof areas were relatively clean. The drywells were dry and contained little sediment. Recommendations All catch basins contained significant sediments and should be cleaned. Although the infiltration basin was designed to empty during rainfall events and is apparently not fully doing so, it did appear to be effective at detaining and ultimately infiltrating flows to it. Risks of allowing it to continue to function as a wetland are that it may build up vegetative matter and eventually lose flood storage capacity or it may clog with fine sediments. Dredging and rehabilitation of the infiltration basin may be required in the future. Woody vegetation should be removed from the infiltration basin and the entire basin should be mowed at least annually to prevent establishment of woody vegetation. Proprietary unit maintenance recommendations include a visual inspection every 90 days and cleaning when 1” of sediment is present in front of the oil reservoir. Well more than 1” of material was observed; therefore, this unit should be cleaned by a qualified professional.

A-61 A-62 Stormwater Inspection Report 33 Empire Tractor Owner: Empire Tractor Facility Address: 638 Route 13 Date Inspected: 8/8/22 Inspected by: K. McGrath Overview The stormwater facilities were designed by Resource Associates (Wayne Matteson, P.E.) as described in the October 2010 SWPPP and associated design documents. The stormwater system consists of grass-lined swales that convey runoff to a forebay/settling basin that then flows to a grass-lined infiltration basin. One swale runs west to east along the south side of the building, to the forebay located southeast of the building. The other swale flows west to east along the north side of the building, and then north to south to the forebay. A stone-lined weir outlet structure allows flow to pass to the infiltration basin. The original design included a storm drain overflow outlet to the ditch on Rt. 13. It appears that this was not constructed. Observations The northern portion of the swale that runs along the east and then south sides of the property does not exist as indicated in original drawings. It begins about halfway down the building on the gravel edge and continues southeast, turning 90o southwest at the back of the building, and discharging into the forebay southwest of the building. The portion of this swale along the southeast corner appeared to lack grade and some areas contained pools or mud and lacked vegetation. The northern portion of the western swale appears to be cut off from the remainder by an access road to an equipment storage area although the owner reports that a 6” culvert pipe was installed under this road. Thus, it is unclear whether the upper section of swale effectively drains under this road. The northern portion of the remaining section of this swale contained water and appeared to lack sufficient grade to drain. The remaining southern portion of this swale was dry. Very small patches of bare soil were observed along this swale. All swale areas were mowed and well-maintained with only small areas lacking vegetation because of water pooling as described above. All areas were free of debris or woody vegetation. The forebay contained vegetation that had not recently been mowed but included little to no woody species. The infiltration basin was mowed short as lawn. Spillways were rocked and covered with vegetation that was not woody. No debris or woody vegetation was seen in the forebay/infiltration basin complex. Very small patches of bare soil were observed in the infiltration basin. A-63 Generally the entire stormwater management system appeared to be well-maintained and functioning effectively. Recommendations The eastern swale appeared to lack positive grade; it was unclear how this area was originally designed to handle stormwater. Along the western side of the building, the northernmost section of grassed swale may not drain effectively. No significant problems associated with drainage were observed. However, it is unknown whether these areas will drain adequately following larger storms. The minor areas of the swales and infiltration basin that lacked vegetation should be reseeded and mulched. SWCD will visit the facility in 2023 during wet weather to assess whether swales are draining effectively.

A-67 Stormwater Inspection Report 34 Redding Reloading Equipment Owner: Redding-Hunter Inc. Facility Address: 1089 Starr Rd Date Inspected: 7/13/2022 Inspected by: K. McGrath Overview The stormwater facilities were designed by Keplinger Freeman Associates as described in the June 2011 SWPPP and associated design documents. The stormwater system consists of 2 infiltration basins with dry well overflows. The basins are located at the northwest corner of the property. Runoff from the paved areas flows overland to the basins. The grass-lined basins have 6 inches of sandy loam topsoil, overlying 6 inches of run-of-bank gravel, overlying filter fabric. Each basin has an 8-foot diameter dry well. Grates at the tops of the dry wells allow higher flows to enter. The top of the dry wells are raised about one foot above the bottom of the infiltration basins. The dry wells for the separate basins are connected by a 24-inch diameter perforated drain pipe to promote infiltration from the dry wells. Observations Infiltration basins were clean and well-vegetated. It was unclear whether they were effective depressions concentrating flow toward the dry wells. Rather, these areas appeared to slope to drain offsite, away from the dry well, with limited to no contact with the grassed water quality treatment areas and limited potential for discharge to the dry wells. Observation during wet weather would be required to assess effectiveness of these treatment areas. Both dry wells were clear of sediment or debris and were dry during the inspection. A catch basin with connection to the southwestern dry well is indicated on site design drawings, toward the southeast corner of the property in the entrance driveway. No evidence of this structure was present during the inspection and an asphalt patch was present in the area where it might have been. It is unclear whether it was ever built. Stormwater from this area drains south to Starr Road and then along the road toward the east. The property was observed by SWCD during wet weather and only small portion of the asphalt area described above drained to Starr Road that would have drained to the catch basin if it had been installed and was operational. Other than the potential redirection of flow away from the dry wells, there was no evidence of problems with the operation of the system. A-68 Recommendations SWCD will visit the facility in 2023 during wet weather to determine whether the infiltration basins serve their intended purpose and flow is toward the dry wells.

A-72 Stormwater Inspection Report 35 Squeaky Clean Owner: MY RYAN LLC Facility Address: 1081 Route 222 Date Inspected: 7/22/2022 Inspected by: K. McGrath Overview The stormwater facilities were designed by Buck Engineering as described in the 2004 SWPPP and associated design documents. The stormwater system consists of 3 dry wells for roof runoff and 3 dry wells for pavement runoff. Catch basins capture runoff from paved areas and convey it to the dry wells through storm drain pipes. Trench drains at the entrances to the carwash areas also convey runoff to 2 of the dry wells. A sand layer associated with the dry wells receiving pavement runoff serves to provide water quality treatment. Observations The property appeared clean of debris and appeared to be well maintained. All three dry wells draining roof leaders were dry and contained relatively little fine material or trash. The catch basins and dry well draining the northern portion of the property contained some water. At the time of inspection the business was open and several customers were washing cars, so this is not unexpected or an indication of poor functioning. The catch basins draining the western/central portion of the property contained some water but the dry well was dry. However, this dry well contained a complete layer of fine sediments on the surface of the rocked infiltrating area. The catch basins draining the southern portion of the pavement contained water but the dry well was dry. This dry well also contained fine sediments on top of the original design surface. Catch basins contained 3-9” of sediments and sediments were only a few inches below the outlet invert in several cases. Although the first third to one-half of each French drain contained fine gravel, the lower ends of each were clean. They appeared to be functioning adequately. A-73 Recommendations 1. All catch basins should be cleaned because sediment deposit depth in the sump is greater than or equal to one-third the depth from the basin invert to the lowest pipe or opening into or out of the catch basin. 2. Sources of fine sediments draining to the dry wells should be identified and removed, if possible. Fine sediments in a dry well clog pore spaces within the drainage medium and shorten the well’s performance life before renovation is required.

McGrath Overview Although developed as one property with multiple tenants, the property was subdivided in approximately 2018, separating the McDonalds and the Aspen Dental Mall properties into separately owned properties (approximate property line indicated on the Layout figure below (yellow dashed line). Stormwater facilities were designed to address stormwater on the entire original parcel. All stormwater facilities are located on the Cortland Commerce Retail Center property; stormwater from the McDonalds property continues to be addressed on the Cortland Commerce property. The stormwater facilities were designed by QPK Design as described in the March 2012 SWPPP and associated design documents. The stormwater collection system for the property consists of catch basins and storm drains that convey runoff to two forebay/infiltration basin complexes. Roof runoff is piped directly to one of the forebays. Upland (off-site) runoff from the south is conveyed by a storm drain to an off-site infiltration basin at the corner of Lime Hollow Road and Route 13. Observations The two properties were inspected at the same time. All five catch basins were observed. They contained 2 to 8” of water and 1” or less of sediments. Most vegetated areas were well-maintained and well-vegetated and contained no undesirable woody vegetation. The eastern forebay contained significant water; retention of stormwater is reducing capacity available for water quality volume (WQv) treatment in future. This forebay may not have sufficient capacity to meet stormwater regulation requirements for WQv treatment and may require renovation. A-79 The western forebay contained no water but clearly retains water regularly as wetland vegetation and wet sediment were observed. Considerable storage volume continued to be available for retention and water quality treatment in this forebay. Both infiltration basins treating onsite stormwater were dry and generally well-vegetated and showed no evidence of long-term water retention. One surface drainage inlet directly into the northwestern infiltration basin was eroding and appeared to be contributing sediments to that infiltration basin (red oval indicated on the attached aerial and inspection photo). Areas around trees immediately above this infiltration basin lacked vegetation from mower wheel damage (circled in aerial and photo). The bypass infiltration basin was also dry during the inspection but showed evidence that it recently held water. It appears to be draining adequately. Recommendations Forebays should be observed to determine whether inability to drain is detrimentally affecting their performance for water quality treatment. The erosional area to the northwest infiltration basin should be stabilized with rock to reduce erosion. Mowing should be modified to avoid mower wheel damage. Bare areas should be revegetated. These maintenance activities will reduce sedimentation and prolong the life of the infiltration basin. Catch basins require no maintenance at this time but should be cleaned when sediment deposit depth in the sump is greater than or equal to one-third the depth from the basin invert to the lowest pipe or opening into or out of the catch basin.

The stormwater system as designed was to consist of vegetated swales on each side of the property draining northwest to the Rte 13 road ditch and two infiltration basins immediately along Rte 13. Bypass drainage is routed into the swale to the southwest of the property and discharges into a small infiltration basin at the road. The swale routing stormwater from the property begins at the back of the property, runs northeast to the property corner, and then runs north parallel to the property line. It drains into a large infiltration basin in front of the property along Rte 13. Both basins discharge to the Rte 13 road ditch. Neither basin has a forebay. The southwestern infiltration basin designed to receive bypass flow was not constructed according to the original design on file with the Cortland County SWCD. Rather, it is considerably smaller than the original design and appears oriented 90o from the original design. There was no evidence of problems associated with the reduction in size. Observations Both grassed swales were generally well-vegetated and mowed with no woody vegetation, erosion or debris observed. The primary swale had a few small bare spots along the asphalt edge likely from vehicular damage. The large northwestern infiltration basin has been significantly renovated since the 2019 SWCD inspection. All wetland vegetation such as cattails has been removed and the basin was well- vegetated with upland species such as grass and clover. One woody shrub was established on the basin sideslope. The basin was dry during the inspection suggesting effective infiltration. The rock spillway between the grass swale and the large infiltration basin had considerable bare soil and the embankment immediately adjacent to the outlet structure had small areas of bare soil. The rock spillway to the road ditch was free of any significant vegetation. The outlet structure contained a small quantity of water and some large pieces of trash. It is unclear how the trash got into the structure other than by backward flow from the road ditch. The inlet to the structure was partially plugged with trash that was likely impeding flow. A-85 The bypass basin and spillway were difficult to observe because they had not been cleared of vegetation recently and contained woody species such as boxelder. Recommendations Woody vegetation on the bypass spillway and the one shrub on the primary infiltration embankment should be removed and these areas should be maintained to prevent future establishment. Bare areas should be seeded and mulched to reestablish vegetation. The inlet to the infiltration basin outlet control structure should be kept free of trash. A-86 Layout Tractor Supply Co.

A-88 A-89 Stormwater Inspection Report 56 Gutchess Lumber Sports Complex Phase 1 and Amendment Owner: Town of Cortlandville Facility Address: 3111 Byrne Hollow Crossing Date Inspected: 7/22/2022 Inspected by: K. McGrath Overview Phase 1 includes construction of two baseball fields, a playground, parking areas and associated roads and other infrastructure. The project was designed by CHA Consulting, Inc. as described in the March 2018 SWPPP and associated design documents. Included in 58a, Phase 1 are modifications and additions completed and reviewed in 2020 and included in an amended SWPPP dated May 2020. The 2020 amendment consisted of construction of a bathroom building, a storage building and a pavilion. The Phase 1 stormwater system consists of drainage ditches/grassed swales along the outer edges of the baseball fields that drain to 9 dry wells and 3 bioretention areas draining the parking lot north of the fields. Five of the dry wells are distributed along the southern edge of each baseball field and the remaining four are distributed running north-south between the two fields. The eastern most edge of the project area drains south to a natural low area and infiltrates on site. The three bioretention areas are located within and immediately to the east of the parking area. The 2020 amendment (addition) included stormwater facilities consisting of two bioretention areas south of the storage building receiving drainage from this building and adjacent driveways and small parking area. Stormwater associated with the bathroom building likely infiltrates into adjacent grassed areas. The pavilion drains into the existing grassed swale/dry well system as well as infiltrating directly into adjacent grassed areas. Observations Weather had been very dry prior to the inspection. The original construction of two baseball fields, entrance road and northeast parking area, stormwater facilities associated with these amenities, and of the 2020 additions, the pavilion, playground and restroom building areas were inspected. The storage building and associated drive, parking area and stormwater facilities have not yet been constructed. The three bioretention areas associated with the northeast parking lot were mowed and contained little trash or debris. Numerous small bare soil areas were observed. Lack of vegetative cover appeared either to not have been successfully established initially or a result of damage from mower wheels. Most of the damage was at sharp slope changes at bottom or top edges of the bioretention areas. A-90 Grassed swales were generally well vegetated, maintained and free of trash or other debris. Numerous small bare soil areas were also observed in swales, in similar locations as in the bioretention areas as well as in the swale bottom surfaces. Large lawn areas draining to the swales, with the exception of around the restroom building, were generally well-vegetated, mowed and free of trash or debris. Grass around the restroom building was thin or bare and very poorly established. All nine dry wells were inspected. Wells #4, #7 and #9 as indicated on the layout diagram below contained water during the inspection indicating slow infiltration. Well #8 was dry but included a layer of fine sediments on the top of the infiltrating medium. Many of the dry wells had bricks or other large rocks in them, likely deposited during construction. These materials should not affect performance. Many of the dry wells had significant bare soil areas immediately around the drainage grates. New parking areas were apparent during the inspection that were not included in original proposals. No stormwater facilities appeared to have been constructed to manage stormwater from these impervious surfaces and it is not known whether stormwater facilities are planned. Recommendations All bare grassed areas should be reseeded and mulched to establish a complete vegetative cover as required. Stormwater management facility needs should be evaluated and installed as necessary to address new parking areas north and west of the bathroom building on both sides of the entrance road. Sources of fine sediments draining to the dry wells, particularly the dry wells containing water during the inspection, should be identified and removed if possible. Fine sediments in a dry well clog pore spaces within the drainage medium and shorten the well’s performance life before renovation is required. Renovation of these wells may be required in future if infiltration becomes unsatisfactory.
