Appendix A - Sewer Study – (Study regarding the sewer capacity) Labella Associates completed a sewer study to analyze the potential impact of the proposed development would have on the existing sewer infrastructure and to confirm the available capacity. Results from the sewer study conclude that the existing sewer has sufficient capacity to handle the proposed project. The increased unit count (75 units) did not increase the impact on the sewer load. Of the three sample locations, the highest existing flows recorded during the monitoring period showed the existing 60” Sewer (Casmier Street) peaking at 34.6% of its total capacity. The proposed project would increase the load to 34.8% (dry weather weekend day peak). At the two other sample locations (Mathews Cemetery NW Corner and 8 Cable Street), the proposed project would increase peak flows to 10.3% and 33.3% of the total sewer pipe capacity respectively (dry weather weekend day peak). TEC Smith was contracted to install monitoring nodes in existing manholes as directed by Erie County Department of Health. Sanitary flows were monitored in three downstream manholes from August 13, 2024 – September 18, 2024. The data was provided and Labella Associates completed the sewer analysis report. Attached in Appendix A, with all supplemental node data provided to the town under separate cover. Refer to Appendix A for the sewer report, as prepared by LaBella Associates (Kristopher Winkler, P.E.) Appendix B - DOT – Traffic Study Correspondence Labella and Home Leasing met with the New York State Department of Transportation, Region 5 staff on 8/6/2024 to discuss if any traffic studies would be required in addition to the original traffic assessment prepared by Labella Associates (Traffic assessment dated 6/13/2024). The meeting was held with Casey Gordon, Ronald Frei and Carl Calarco of the DOT. The DOT is not requesting any additional traffic assessments at this time. The Traffic Assessment originally provided is sufficient. The original traffic study is based on 75 units – an update was not needed as part of this resubmission. Email correspondence confirming the DOT position via Casey Gordon, Transportation Analyst is provided in Appendix B. Appendix C - Electrical Capacity – Grid Capacity Evaluation (GCE) Labella Associates has prepared a Grid Capacity Evaluation (GCE) to provide insight into the available electrical capacity for the proposed project. The original report was updated to reflect 75 units and the gross square footage of the new building layout. The singular building design results in more efficient layout in regard to energy usage. Updated results from the Grid Capacity Evaluation found that the proposed project would increase the load on the 12.5kV circuit to 56.1% (in leu of 83.5% with the original layout) of its available capacity (if constructed at the time of the report). This is well below the maximum peak percentage, therefore is Labella’s opinion that the project can be serviced without additional upgrades from NYSEG. Based on previous experience, if the total peak percentage is below 90%, the proposed developments can be serviced without upgrades. The GCE evaluation looks at the current capacity of the electrical grid in the area and estimates the electrical load that the proposed project would potentially add to the existing infrastructure.
