Proposal from Princeton Hydro Engineering, dated June 12, 2026, for a pond evaluation and dam inspection at Kaplan's Pond at a total fixed fee of $8,500, with a $1,000 retainer to initiate services. The pond evaluation, set for a single summer 2026 site visit, would sample water quality including phosphorus, nitrogen, and chlorophyll, analyze phytoplankton and zooplankton including cyanobacteria that can form harmful algal blooms, and assess invasive aquatic plants. The dam inspection would be a visual inspection generally following 6NYCRR Part 673.12(d), noting the structure does not meet criteria for DEC regulation and was reworked in 2004.

Mr. Frank Balbi, PE Superintendent of Public Works Village of Croton-On-Hudson 435 Yorktown Road Croton-On-Hudson, NY 10520 RE: Kaplans Pond – Pond Evaluation and Dam Inspection Croton-On-Hudson, New York June 12, 2026 Dear Mr. Balbi, Princeton Hydro Engineering, PC (Princeton Hydro) is pleased to provide this proposal for services in support of Kaplan’s Pond. It is our understanding that concerns have been raised about the pond. As such, the Village of Croton-on-Hudson (Village) is interested in an overall assessment of the pond to identify any maintenance or upgrades needed to improve the pond. A combined dam and pond assessment is a crucial first step in understanding the current conditions and potential issues. A detailed scope of services is presented within the following pages. If you concur with the scope of services and fees, please sign and return one (1) copy of the attached Professional Services Agreement and Standard Terms and Conditions. We will also require a retainer of $1,000 to initiate services. We look forward to working with the Village of Croton-On-Hudson on this pond assessment. If you have any questions or require additional information to facilitate your review of our proposed scope of services and costs, please do not hesitate to contact me directly at mhartshorne@princetonhydro.com or 484-566-9548.

Senior Project Manager/Senior Geotechnical Engineer, Princeton Hydro Marissa Ciocco, Project Manager/Geotechnical Engineer, Princeton Hydro Princeton Hydro, LLC Page | 2 TASK 1A: POND EVALUATION Princeton Hydro will conduct an evaluation of the ecology of the pond during a single site visit to be conducted during the summer of 2026. This monitoring will evaluate water quality, aquatic plant growth, and plankton including those that can form harmful algal blooms (HABs). Princeton Hydro will monitor the water quality of the pond at a single location which represents the deepest point of the pond. During this monitoring, we will sample in profile in-situ temperature, specific conductance, pH, and dissolved oxygen in profile at 0.5 to 1 m intervals throughout the water column. Transparency will be measured with a Secchi disk. In addition, we will monitor critical parameters related to nutrient enrichment and algal growth. Specifically, samples will be analyzed for total phosphorus, soluble reactive phosphorus, ammonia, nitrate, total suspended solids, and chlorophyll a. These samples will be collected from the surface (0.5 m below the water surface) and deep (1 m above the sediments) depths with the exception of chlorophyll a which will be collected from the surface only. Discrete laboratory samples will be analyzed by Environmental Compliance Monitoring of Hillsborough, New Jersey. In addition, a single sample will be collected for both phytoplankton and zooplankton. Each plankton sample will be taxonomically analyzed to lowest practical taxon, typically genus, and enumerated. Cyanobacteria, which may form HABs, will also be identified and enumerated. In addition, during the survey, we will assess the pond for the growth of aquatic plants and describe any non- native, invasive species of concern or growth which may otherwise hamper the ecological condition and usage of the pond. At the completion of the survey, and upon receipt of all data, we will prepare a letter report which summarizes all findings and implications for pond management. TASK 1B: DAM INSPECTION Princeton Hydro will inspect the dam during a single site visit. The Village indicated that the structure does not meet criteria for DEC regulation. As such, a visual inspection will be performed in general accordance with 6NYCRR Part 673.12(d). This will include the completion of all pertinent forms, collection and organization of pictures, discussion of previously reported conditions, and the incorporation of the findings into a complete inspection report. It is understood that the structure was reworked in 2004. If available, it would be helpful to review any documentation related to the construction and the conditions of the dam pre and post construction. A representative from the Village does not need to be present during the inspection; however, we will contact you in advance of the inspection so that you are aware when we will be on-site. If during the inspection any structure appears to need critical attention, the Village will be contacted immediately. TASK 2: ADDITIONAL SERVICES The purpose of this task is to provide any additional services that you may request. These services may include meetings, additional work products, additional site visits, etc. No work effort will be completed under this task Princeton Hydro, LLC Page | 3 without your prior approval. This task will be completed on a Time and Materials basis in accordance with our 2026 Rate Schedule, which is attached to this proposal.
