Section 1: Introduction

Overview of Project

The Village of Cazenovia is seeking proposals for professional engineering services to design, permit, and provide construction management for the removal of the Mill Street Dam located on Chittenango Creek and for restoration and improvement of the creek channel and riparian corridor. The selected consultant will complete a detailed design for the dam removal, stream habitat enhancement and restoration, conduct hydrologic and hydraulic modeling of the creek as needed to supplement prior modeling, prepare, submit, receive, and ensure compliance with all required permits, prepare final construction drawings and plans and specifications, provide construction oversight, and work together with Village and local stakeholders over the course of the project.

The Mill Street Dam is located on Chittenango Creek in the Village of Cazenovia, Madison

County, New York. A map of the portion of the Village surrounding the dam site is shown in

Figure 1. The dam is owned and operated by the New York State Canal Corporation (NYSCC). It was constructed by New York State in 1857 as a part of the project to expand the original Erie

Canal. Operation of the Mill Street Dam, together with the Upper Dam, also known as the Lake

Dam (Figure 1), allowed water from upper Chittenango Creek to flow into Cazenovia Lake during high water events to be stored for later release back into the Creek. A portion of this augmented creek flow was diverted into the expanded Erie Canal to maintain navigation in the Canal. With the closing of the expanded Erie Canal in the early 20th century, the Mill Street Dam is no longer required for NYSCC operations nor does it provide other beneficial use. The Mill Street Dam was not constructed, nor has it ever been operated, to provide flood control in Chittenango

Creek. The Lake Dam is used to control the level of Cazenovia Lake. The NYSCC owns and remains responsible for operation and maintenance of both dams. Today, the Mill Street Dam continues to function as originally designed, with flow from the upper Chittenango Creek into

Cazenovia Lake during high flow events carrying high concentrations of nutrients and suspended solids into the lake, contributing to weed and algae growth and sedimentation in the lake.

The Village of Cazenovia has completed a Phase 1 Preliminary Conceptual Design study to analyze the impact of the Mill Street Dam backflow events. Please see the summary details of this report in Appendix A. This study confirmed that the Mill Street dam removal would greatly reduce the frequency and duration of backflow events and a well-designed stream habitat enhancement and restoration effort would provide significant ecological benefits. Based on these findings, the Village applied for and received a grant from New York State to prepare a detailed design for dam removal and restoration of the creek channel, obtain required permits and approvals, and proceed with dam removal and channel restoration. The Village of

Cazenovia is seeking an engineering consultant through this Request for Proposals (RFP) for final design services, permitting, and construction and project oversight for the dam removal and stream habitat enhancement and restoration.

2.1 Preliminary Engineering Design and Analysis (30% Design)

The Preliminary Conceptual Design completed in the previous phase (see Section 7:

References), should provide the majority of what is needed for the 30% design. The selected firm will review the Preliminary Design and utilize the hydrology and hydraulic models as well as the schematic design drawings of the current dam structure. These resources should be added to and amended only as needed to achieve the 30% design.

The following are the high-level minimal components which should be included in the 30% design.

Dam inspection and additional hydrology and hydraulics modeling if needed. Perform required work to meet permitting requirements.

Incorporate the base mapping completed in the preliminary study and supplement if needed. This includes elevations, utilities, right-of-way, easement, and other pertinent features.

Develop preliminary design drawings accompanied by a design memorandum that outlines proposed methodology for removal based on the preliminary design. Design should show post dam removal views and stream habitat enhancement and restoration, alternative removal and restoration methodologies considered, and initial recommendations for sediment management.

Start preparation of any permit applications, conduct initial meetings with permitting agencies (SHPO, DEC, USACE, NYSCC, etc.), and help educate the public, government funders, and permitting agencies by creating graphic interpretations of what the project will look like once completed.

Assist village officials in addressing any comments or concerns generated from any permit application reviews.

Deliverables:

- Hydrology and Hydraulics Modeling (HEC-RAS) as required and updated as needed

- Preliminary Design Drawings (30% plan submission)

- Design Memorandum in PDF describing above items

- Alternative Analysis report if required by SHPO

2.2 Engineering Design (60%, 90% and Final Design)

These interim design phases shall include (but are not limited to): proposed removal methodology and site restoration plans; wetland and forest mapping, sediment management planning, grading plan, erosion and sediment control plan; planting plan;

identification of any infrastructure and limits of disturbance; and construction sequencing.

Additionally, as described below, design options created by the U.S. Fish and Wildlife Service

(FWS) for stream habitat enhancement and restoration will be integrated with the dam removal design.

60% design review package shall include electronic copies (PDF) of the design plan set and a design report summarizing modeling results, design methodology for dam removal and site restoration, sediment management, grading, stream habitat enhancement and restoration, etc.

60% design review package shall also include an opinion of probable cost and draft specifications. The package shall also include the set of hydraulic model inputs which incorporate or include the detailed features of the restored dam site and the modified

Chittenango Creek channel. The design components shall be identified including project boundary definition; adjoining landowner information; location of known utilities; extent of any excavation; estimate of the dam’s concrete and masonry removal volume; estimate of sediment removal volume and location if needed; location of construction access points and potential access stabilization measures. In addition, the stream restoration final design, completed in coordination with FWS, will include stream habitat enhancement and restoration (i.e., rock veins/riffles) and streambank stabilization measures to ensure success of the project. The detailed features of the restored creek channel and riparian corridor should be described in documents and depicted in drawings and should be reflected in the model simulations.

90% plan review package shall include updated versions of these deliverables.

Final permitted plans and contract documents, including all drawings and specifications necessary for construction bid shall be required for final 100% design completion. These must be signed and sealed by a PE licensed in New York. If comments are received by permitting agencies, these will be addressed and a final construction drawing set will be issued addressing any comments.

Deliverables:

2.3 Stream Habitat Enhancement and Restoration

This project has two components: dam removal and stream habitat enhancement and restoration. While the design of these two components may be undertaken independent of each other, the Consultant should ensure that these two components of the final design are compatible and will perform in an integrated and complimentary manner.

The FWS has prepared a conceptual design for the in-stream restoration. The Village and local stakeholders have continued to work with FWS in order to bring their expertise to bear on the final design for this project. The Village will enter into an Agreement with FWS which describes the services that will be provided by FWS as part of this project. The Consultant will utilize these designs and work in cooperation with FWS in a manner that is consistent with this

Agreement. The Consultant shall work closely with FWS in evaluating alternative designs and in fine-tuning design features for the stream habitat enhancement and restoration component.

The Consultant should include in their proposal their costs that are associated with this cooperation with FWS. As specified in the Agreement, FWS will provide these services and will contribute to the final design on an in-kind basis, at no cost to the Village or the Consultant.

Because of FWS’s numerous stream restoration projects on Chittenango Creek it is expected that there is a cooperative collaboration with FWS to ensure the best outcome.

Appendix A

This section is a high level summary of the Phase 1. For the complete report please see the

References.

A hydrologic model (HEC-HMS) was applied to the watershed draining directly to Cazenovia

Lake, and the watershed of Upper Chittenango Creek (upstream of the confluence with the lake outlet channel). Together these two watersheds constitute the watershed at the site of the Mill

Street Dam. Data which describes the characteristics of these two watersheds was assembled.

In addition, rainfall depth/frequency/duration information for the watershed was compiled from NOAA and Northeast Regional Climate Center sources. For the analysis of backflow into

Cazenovia Lake, the hydrologic model was used to simulate five hypothetical runoff events: 5-year, 2-year, 1-year, 75% of 1-year, and 50% of 1-year. For the analysis of flooding downstream of the dam site, a 100-year runoff event was also computed. The duration of each of these simulated events was 4 days.

A hydrodynamic model (HEC-RAS) was applied to Cazenovia Lake, the Lake Outlet channel, and the portion of the channel of Chittenango Creek upstream and downstream of the Mill Street

Dam site and within the Village of Cazenovia. The hydrographs for the five events were input to the hydrodynamic model to compute water surface elevations, stream discharge and velocity for each event. All of these simulations were completed for two conditions: the current condition with the Mill Street Dam is in place, and with the dam completely removed. These simulations were completed for three different Cazenovia Lake levels, and two different gate openings at the Lake Dam. Of primary interest is the computed backflow from Chittenango

Creek into Cazenovia Lake for the various streamflow, lake elevation, and lake dam gate conditions.

The following is a summary of the findings:

Dam removal significantly reduces the frequency and volume of backflow under all conditions

For the 3 smaller runoff events, backflow is eliminated with dam removal

For the larger, more infrequently occurring 2-year and 5-year events, backflow is reduced but not eliminated with dam removal;

For the 2-year event, the average percent reduction in backflow volume was 94%; for the 5-year event, the average reduction was 63%.

With the dam removed and considering the 2 larger events, if Cazenovia Lake level at the start of the event is increased, backflow volume is reduced

Similarly, with the dam removed and considering the 2 larger events, if the gate opening at the upper Lake Dam is increased, the backflow volume is reduced

It was found that during the 5-year and 100-year events, if the dam is removed, water surface elevations in the creek downstream of the dam site will rise slightly

2.2 Volume and Character of Sediments

The Phase 1 report, provided in the references, reviewed issues related to the sediment that has accumulated in the creek channel upstream of the Mill Street Dam, the extent of potential contamination of this sediment, and the potential need for dredging or removal of sediment.

The Phase 1 study analyzed federal and state databases to identify any hazardous waste remediation sites or spill occurrences in the Mill Street Dam watershed. No current or former hazardous waste sites are identified in the watershed. The New York State Spill Incidence

Database identified the occurrence of three minor spill incidents in the watershed, occurring in

2022 (two) and 2023 (one). A single gasoline storage tank currently exists in the watershed, with no incidents reported. Based on this review, the Phase 1 report concluded that contamination associated with spills or hazardous waste remediation sites are not expected to be present in sediment at the Mill Street Dam site.

In April 2025, four sediment samples were taken by the Cazenovia Lake Association from the stream bed upstream (west) of the Mill Street Dam, between the dam and the Mill Street bridge. The samples were taken at a sediment depth (below the channel bottom) of 1.2 to 1.8 feet. Please see the figure below which shows the sampling locations.

All samples were analyzed for the following heavy metals: chromium, copper, cadmium, lead, and mercury. A duplicate digestion was performed on each of the four samples. Analyses were performed at SUNY-ESF; no interpretation of the laboratory analyses accompanied the report.

The results are shown below.

These results are the only known analyses of the chemical character of the sediment that has accumulated upstream of the Mill Street dam. There are no known analyses of the grain size distribution, nor are there estimates of the total volume of sediment that has accumulated since construction of the dam.

2.3 Natural Resources

Using the NYS Environmental Resource Mapper (ERM), a preliminary review was performed to identify rare, threatened, and endangered (RTE) species. No RTE species were identified in the

Project area. However, the search indicated that regulated wetlands are present, so that wetland delineation will be required in this project.

2.4 Cultural Resources

A review of the dam site using the State Historic Preservation Office (SHPO) online Cultural

Resource Information System (CRIS) was conducted in Phase I. The database indicated that the dam is listed on the historic registry. Therefore, any construction or demolition at the dam site will require prior consultation and approval with SHPO.

2.5 Preliminary Conceptual Design of Channel Improvements and Restoration

As a part of the Phase 1 project, the Village and local stakeholders worked with staff from F&W to discuss improvements and restoration to the channel of Chittenango Creek following removal of the dam. These discussions led to the completion of a preliminary conceptual design for improvements produced by F&W. Their stated goals for this restoration project are to restore a free flowing river to allow fish passage, enhance stream habitat, reduce concentrations of bedload and suspended sediment, attenuate floodwater by improving floodplain connectivity, and provide stable conveyance of streamflow. As part of this stream restoration, it is assumed that stream bed elevations around the dam removal site will have to be altered to allow for proper water flow and fish passage. The conceptual design includes in-stream structures, including 3 rock cross vane structures, and a single toe wood structure. The design also recommends two zones of trees and shrubs to be planted, with riparian trees and shrubs planted within 5 feet of the top of bank at a density of 350 stems per acre., and additional vegetation stabilization at higher elevations that are less frequently inundated. A link to the conceptual design documents provided by F&W is available in the references.
