November 23, 2016 Mr. Joel DuBois, Program Specialist Greene County Soil & Water Conservation District 907 County Office Building Cairo, NY 12413 Re: Proposal to Complete a Local Flood Analysis for the Village of Tannersville, Village of Hunter, and Town of Hunter Dear Mr. DuBois: Gomez and Sullivan Engineers, DPC (Gomez and Sullivan) is pleased to submit our proposal to provide support for a Local Flood Hazard Mitigation Analysis (LFA) for the Village of Tannersville, Village of Hunter and Town of Hunter, NY (the Hunter Corridor communities). As requested, this proposal includes our technical proposal (including experience, organizational capability, and proposed technical approach), as well as our price proposal and acknowledgement of addenda. Gomez and Sullivan has been providing specialized engineering and environmental science services to the water resources community since 1993. Our staff of approximately 50 individuals based in New Hampshire and New York includes hydraulic, environmental, civil, structural, geotechnical, mechanical, and electrical engineers, as well as environmental scientists, ecologists, fisheries biologists, hydrogeologists, geologists, fluvial geomorphologists, regulatory specialists, planners and GIS specialists. We utilize our in-depth understanding of hydrology and hydraulics and ecology, as well as the regulatory environment, to evaluate, plan, and design flood mitigation projects and ecosystem-based restorations in riverine and wetland environments. We have extensive experience in communicating controversial and complex information to a non-technical audience, and understand the need for effective public outreach throughout a project to ensure its success. We are well versed in the use of benefit-cost analysis and the preparation of grant applications as tools to successfully identify and secure funding for restoration projects. Our project approach is founded on our experience with the regional hydrology and our first-hand observations of the devastating impacts of pronounced flooding due to recent events caused by the landfall of tropical storms in the area, and heavy localized rainfall/thunderstorms in the watersheds surrounding the Hunter Corridor communities. We completed Flood Insurance Studies (FIS) for the portions of Ulster County outside of the New York City watershed (2009) and for Albany County (March 2015), and conducted hydrologic and hydraulic modeling for the ongoing FIS revisions in Ulster and Delaware Counties. Due to our close geographic proximity and expertise, we were enlisted to assess and document the impact of Hurricane Irene and Tropical Storm Lee in various parts of Delaware County. We understand the significant flooding potential that exists in the area, which drives our desire to analyze, develop, and design options to mitigate flood impacts and help protect communities. We look forward to the opportunity to work with the GCSWCD and the Hunter Corridor communities to help mitigate flood hazards.



Upon review of our proposal, we believe that you will consider us an excellent choice for this assignment due to our practical experience, diverse capabilities, and enthusiasm towards this type of work.

C. PROPOSED TECHNICAL APPROACH Background & Understanding

The Greene County Soil and Water Conservation District (GCSWCD), on behalf of the Village of Tannersville, Village of Hunter, and Town of Hunter (the Hunter Corridor communities), is seeking to complete a Local Flood Hazard Mitigation Analysis (LFA) for these municipalities. The project will include the hydraulic analysis required to determine the feasibility of mitigation alternatives, the benefit cost analysis required for project prioritization, environmental and social impact assessment of proposed project, and public outreach to municipalities, organizations, environmental groups, and other technically

oriented interest groups. Throughout the project, close coordination will occur with the following project partners, including the GCSWCD, Flood Advisory Committees, and the Village and Town Boards.

The project is located in two separate study areas, the Village of Tannersville (to be modeled as Phase 1) and the Village of Hunter and Town of Hunter (to be modeled as Phase 2). Stream lengths within the study areas were estimated as follows:

Streams within Tannersville Study Area Distance (ft) Allen Brook 4,144

Gooseberry Creek 15,440 Sawmill Creek 6,320

Unnamed stream west of NYS RT 23A Bridge 1,443 Streams within Hunter Study Area Distance (ft)

Gooseberry Creek 3,765 Schoharie Creek 36,791

Several road-stream crossing structures have been identified as high priority areas for analysis, including but not limited to:

Stream Structures Allen Brook Route 23A

Gooseberry Creek Route 23A Clum Hill Road

Sawmill Creek Route 23A Spring Street

Schoharie Creek

Bloomer Road Route 214 Route 83

Bridge Street Deming Road

Gooseberry Creek at Clum Hill Road

Schoharie Creek at Bridge Street


Maps of the two study areas depicting streams, bridges, culverts, and dams are provided in Figures 2 and 3 at the end of this section.

In preparation for this proposal, we performed background research and conducted a site visit on November 18, 2016 to further our understanding of the study area. As part of this effort, the following information was collected and reviewed:

• Greene County Multi-Jurisdictional All-Hazard Mitigation Plan Volumes I & II (Tetra Tech, 2009)

• Draft Greene County Hazard Mitigation and Resilience Plan (AECOM, 2016) • Effective Flood Insurance Study (FIS) for Greene County, NY (FEMA, June 2, 2015) • Magnitude and Frequency of Floods in New York (US Geological Survey (USGS), 2006)

A key aspect of this project will involve hydraulic modeling of proposed mitigation strategies to evaluate impacts. The primary source for baseline models will be those developed for the preliminary FEMA FIS for Greene County, which can represent varying levels of detail. Detailed hydraulic (HEC-RAS) models are developed using in-stream survey, include bridge structures, and designate a floodway, whereas approximate models do not include these features. For the study area, detailed models are assumed to be available for all streams included in this project.

Based on information gained during the site visit, it appears that flooding issues in the Corridor communities are caused by two types of events: 1) large area, long duration storms which result in flooding along the Schoharie Creek, and 2) smaller, local storms which cause more frequent flooding along the study area tributary streams.

We will work with project partners to evaluate mitigation alternatives. This process will include collaboratively identifying flood mitigation goals and objectives and to develop potential actions associated with the following flood hazard mitigation categories:

• Property Protection – Actions that reduce potential damage to buildings, infrastructure and other kinds of physical property (including property acquisition/relocation, elevation or flood proofing of buildings)

• Flood Damage Prevention and Planning – Actions that lower flood water elevations or prevent future losses (such as channel and floodplain modifications, floodplain reclamation, and adoption or amendment of land use regulations, building codes or flood damage prevention regulations)

• Natural Resource Protection – Actions that minimize hazard loss and preserve or restore the function of natural systems (such as soil stabilization measures such as bank protection and

stabilization or landslide stabilization, attenuation of peak flows through detention and enhanced storage, debris management)

• Structural Projects – Actions that use or modify structures to mitigate a hazard (such as replacement or retrofit of bridges and culverts, removal or relocation of structures, buildings, or channel encroachments, protection of critical utilities and infrastructure)

• Emergency Services – Actions that protect people and property during and immediately following a flood

• Community Pollution Prevention – Actions at the community scale that reduce pollution during a flood event (such as securing oil and propane tanks)

• Public Education and Information – Education efforts centered on the benefits of general BMPs, to code enforcement officers, realtors, contractors, municipal officials and property owners about how to protect themselves and the community from flood disasters and associated losses

Approach

As identified in the RFP, we will address this project in two parts. Part 1 (Flood Engineering Analysis) will involve an assessment of existing conditions, hydraulic modeling, identification and evaluation of mitigation alternatives, and the development of Flood Engineering Analysis Reports to summarize the findings. Part 2 (Feasibility Analysis) will involve further assessment of the recommended mitigation alternatives, including assessment of municipal regulations, benefit cost analysis, evaluation of potential water quality benefits, and identification of likely funding sources for feasible options. The project will culminate with the development of a Local Flood Hazard Mitigation Plan for each site.

This project also includes two separate study areas—Tannersville and Hunter—referred to as Phase 1 and Phase 2, respectively in the RFP. It is our understanding that hydraulic modeling tasks (specifically Tasks 3 and 4) are to be completed first for Tannersville (Phase 1) before proceeding to Hunter (Phase 2). Our tentative proposed project timeline, shown in Figure 4 on the following page, reflects this phased approach.

The timeline depicts major project tasks along with corresponding estimated times for completion. The overall schedule for the project is dependent upon the amount of time desired for review of deliverables by and/or meetings with project partners. We would work with project partners at the onset of the project to develop a schedule with interim task completion dates that allows adequate time for reviews and meetings. Note that the timeline does not show the additional planning meetings requested in the RFP (Task 1.5). We would also coordinate with project partners to schedule these meetings at the appropriate time.

Note: Dark blue rectangles show major project tasks along with estimated time for completion. The overall schedule for the project is dependent upon the amount of time desired for review of deliverables by and/or meetings with project partners, as indicated by the light green and light blue ovals, respectively.

KEY


The following tasks present our proposed approach for completing the requested services. The scope items were prepared based on the RFP, the requested deliverables, and our resulting assessment of the work required.

Task 1 – Project Management, Coordination, & Meetings

Project Management & Communications Effective communications with project partners and stakeholders are key to ensuring a successful project. As such, coordination with project partners and stakeholders will occur on a regular basis. We will manage personnel and resources to support the satisfactory and timely completion of all tasks. We will maintain a complete set of project records, including technical data, drawings, reports, project-related correspondence, and financial records.

If scope modifications are necessary, we will prepare detailed man-hour estimates and schedule adjustments for the proposed change. We will work with project partners to expedite any necessary changes so that progress on the project continues efficiently. Similarly, as phases of the project near completion, the project manager will work with project partners to effectively close out each task.

Project Initiation Meetings In order to establish a project plan, the project director and project manager will attend project kickoff meetings with project partners in each study area. We have assumed that both of these meetings can occur on the same day. These meetings will allow the opportunity to establish contact with members of the project team, gain better understanding of the analyses to be performed, and collect feedback on the project approach. Prior to this meeting, we will prepare full-size maps of the project area such that project partners can highlight sensitive flooding areas and preliminarily identify potential mitigation alternatives. It is anticipated that previous or ongoing efforts to identify and mitigate flood hazards within or adjacent to the project area will be discussed at this meeting in order to ensure alignment with such efforts.

Educational Materials We will prepare general and technical educational materials, as well as participate in and contribute to ongoing education and outreach efforts related to the project as requested by project partners. Materials developed under this task may include posters, meeting handouts, etc. For cost estimating purposes, we have budgeted for the development of a full-size poster plot of each study area map as well as 100 printed copies of a color educational flyer for each study area. However, we envision that the specific materials to be developed will be coordinated with project partners.

Public Meetings We have found that public input is a critical component to the success of these types of projects, and, as such, believe a concerted effort should be made to engage the public. Our goal is to work with project stakeholders to identify and document areas of concern and begin building consensus for mitigation early in the project.

The project director and project manager will prepare for and attend four (4) public meetings—two (2) for each study area. The purpose of the initial meetings will be to describe the scope of the project and solicit input relative to historic flooding and property damage, as well as any potential mitigation alternatives. It is envisioned that these meetings will be held at the conclusion of Task 2 (Data Collection & Field Verification). The purpose of the final meetings will be to present the preliminary findings of the


analysis and invite stakeholders to provide feedback on the mitigation alternatives. It is envisioned that these meetings will be held at the conclusion of Task 5 (Flood Engineering Analysis Report).

To notify stakeholders of the meetings, we recommend publishing a brief public notice in a local newspaper and on the Town and Village websites. Additionally, we recommend distributing letters explaining the project background and meeting purpose to owners of properties in potential floodplain areas to encourage their participation.

We will develop a PowerPoint presentation and supporting materials for each meeting. We will circulate the draft materials for review by project partners in advance of the meetings and incorporate one round of comments prior to finalization. We will also document stakeholder comments received during and after the meetings and prepare a brief summary report for each meeting.

Planning Meetings The project manager will prepare for and attend a minimum of four (4) Village Trustee meetings—two (2) for each study area—and (at the option of the Village Boards) six (6) Flood Advisory Committee meetings—three (3) for each study area. We will prepare an agenda and meeting minutes for each meeting.

Progress Reports We will provide monthly written and verbal project updates to project partners, including technical information as appropriate. These updates will include a brief summary of technical work completed and items delivered during the previous month, as well as identify any potential issues that may affect the progress of the project. Additionally, each invoice will include a breakdown of task reports, which will identify each task and the hours spent on each task by each staff member.

Additional Educational Support We will prepare additional general and technical educational materials, as well as participate in and contribute to ongoing education and outreach efforts related to the project as requested by project partners. For cost estimating purposes, we have budgeted for the development of a full-size poster plot of each study area map as well as 100 printed copies of a color educational flyer for each study area. However, we envision that the specific materials to be developed will be coordinated with project partners.

Deliverables • Preparation for and attendance at four (4) public meetings • Preparation for and attendance at four (4) Village Trustee meetings and six (6) optional Flood

Advisory Committee meetings • Meeting minutes for all meetings • Monthly project updates to project partners • Educational support materials (as requested) • Complete set of all records following completion of the project (e.g., model files, maps, datasets,

GIS files, survey records, AutoCAD files, reports, etc.) • Record of time spent on each task (invoices)


Task 2 – Data Collection & Field Verification

Data Collection & Review We will gather and review all available data pertinent to the mitigation of flooding hazards in the Villages and Town, including, but not limited to: mapping, aerial photography, prior reports and analyses, and information on potentially flood-prone structures, infrastructure, and water quality threats within the floodplain. Although much of this information has already been collected in preparing this proposal, it is assumed that the following information will be provided by the GCSWCD:

• Available construction drawings of bridge crossings and structures • Available aerial photogrammetry, topographic mapping, LiDAR based DEMs, and/or GIS data • FEMA FIS, DFIRM, depth grids, and associated surveys and HEC-RAS models • Local flooding reports (e.g., Damage Survey Reports) • Water quality reports • Other available prior reports and analyses • The County’s All-Hazard Mitigation Plans • Stream management plans, including stream feature inventory, if available

The existing information will be reviewed in order to better understand the flood hazards within the study area, as well as the level of analysis that has been previously completed. This review will help to better define the project plan in coordination with project partners.

Resource Material Inventory We will compile and submit a table of the existing data collected, which will list the source and date of the data as well as provide a brief description of information included. This table will be periodically updated as more data is obtained.

Visual Field Assessment Following the project initiation meeting, we will conduct field assessments. We will perform a visual assessment of the stream channels and floodplains in the project areas. The assessment will include identification of low-lying structures, bank and channel conditions, hydraulic controls (such as narrowing of channel width or negative channel bed slope), bank and floodplain vegetation, and general conditions along the stream corridors. Channel reaches will be photo-documented for reference throughout the project. Significant storm drainage discharge points into the stream and locations of known or suspected inadequate road drainage conveyance will also be identified to the extent practical.

Information obtained during the field assessment will be utilized in developing and revising hydraulic models, as well as identifying areas in need of mitigation and potential mitigation alternatives.

Windshield Survey In addition to conducting a detailed visual assessment of the river channel and floodplain, we will also drive throughout the watershed to conduct a “windshield survey” to better understand the contributing drainage area and floodplains. We propose to perform this in conjunction with the visual field assessment.

Water Quality Due Diligence Assessment During the existing information review and field assessment, we will also document potential sources of water quality impairment within the study areas. This will include identifying sources from which


chemicals and contaminants may enter the stream, as well as locations where erosion of stream banks or channel bed may lead to excessive sediment loads. We will also use available GIS coverages of known National Pollutant Discharge Elimination System (NPDES) discharges to list any potential sources of pollution in the watershed. Working with project partners and other sources of local knowledge, we will document any historic cases in which water quality was compromised due to flood events.

Technical Memos We will then prepare and submit a technical memo for each study area summarizing existing conditions. These memos will include an overview of data, mapping, and information obtained during the data collection and field assessment and will identify any constraints and/or deficiencies in the existing available data, including known changes in the system that have occurred following prior data collection. The technical memos will also address the potential for rapid changes within the watershed to impact the studied streams.

Task 3 – Hydraulic Modeling of Baseline Conditions

The objective of this task is to duplicate the results of the effective FEMA FIS models for the study reaches and compare results with published FIS results to identify discrepancies and justify the assumptions used in the models. The models will be reviewed and updated as necessary. The corrected results will be used to map flood inundation areas for existing conditions. The hydraulic modeling will be conducted in accordance with FEMA’s “Guidelines and Specifications Appendix C: Guidance for Riverine Flooding Analyses and Mapping.”

Effective Model We will obtain the HEC-RAS hydraulic models that were used to develop the most recent FEMA FIS for the study reaches. It is assumed that the primary source for existing models will be those developed for the preliminary FEMA FIS for Greene County issued in June 2015. For the study areas, detailed models are available for the Schoharie Creek, Gooseberry Creek, Sawmill Creek, and Allen Brook. Together, these models will collectively represent the “effective models” for existing conditions.

Duplicate Effective Model We will run the effective models as a “duplicate effective model” in accordance with FEMA requirements to ensure that the digital results represent the data published in the FIS. We will produce profile plots to compare the results included in the FIS with those produced by the duplicate effective models. Additionally, the input flows will be compared with data in the FIS “Summary of Discharges” table and the computed water surface elevations will be compared with the “Floodway Data Table.” Any discrepancy between the published model results and those obtained from the duplicate effective model runs will be documented and corrected or justified as appropriate.

Corrected Effective Model We will review the duplicate effective model to ensure that it accurately reflects site conditions observed in the field during Task 2. The review will include the evaluation of Manning’s ‘n’ roughness coefficients, expansion and contraction coefficients, and cross section geometry. If significant discrepancies are found,


the hydraulic model will be revised to reflect current conditions in accordance with FEMA requirements, producing “corrected effective models.” We will also compare model results to the flow and stage data recorded at USGS stream gages and the high water marks collected during recent significant flooding events, where available. If the modeled water surface elevations differ from the recorded peak stages or high water marks by more than 0.5 feet, the models will be adjusted as appropriate to reflect the observed flooding conditions. We will document the justification for any modifications made to the duplicate effective models.

Baseline Model Runs The corrected effective models will be run for the 2-, 10-, 25-, 50-, 100-, and 500-year flood flow conditions utilizing published FIS flow values, where available. The 2- and 25-year flows were not modeled for the purposes of the FIS; thus, these two flows will be defined for each location at which a flow change is specified in the existing hydraulic models based on the regional regression equations provided by the USGS. For locations within the area of influence of USGS stream gages, the flow values obtained from the regional regression equations will be weighted with the values determined by a frequency analysis of the stream gage according to the weighting scheme defined in USGS Scientific Investigations Report 2006-5112 Magnitude and Frequency of Floods in New York.

Floodplain Mapping We will develop flood inundation area mapping for the study areas under the various modeled flows. Inundation maps will be developed for each modeled flow utilizing GIS layers of the cross section locations and the available LiDAR-based DEM. The resulting inundation polygons will be presented on the most recent available aerial imagery.

Flood-Prone Property Mapping The inundation mapping will be utilized to identify properties and infrastructure (e.g., roads, bridges, utilities, etc.) potentially prone to flooding under the modeled flows. It is assumed that a GIS dataset of the parcel data will be provided for this analysis. The likelihood of a property to be flooded will be initially based on the elevation of adjacent grade from available topographic data (i.e., the LiDAR-based DEM). Any available additional data for those properties initially identified as flood-prone (e.g., elevation certificates, FEMA letters of map change, etc.) will be utilized to refine the analysis. If a more accurate evaluation of the susceptibility to flooding for specific structures is desired, a first floor elevation survey can be performed for those structures. We will prepare a map identifying the location and any relevant information pertaining to potentially flood-prone properties & infrastructure.

Technical Memos We will prepare a brief technical memo for each study area summarizing the work completed under Task 3. This memo will include information regarding the hydraulic model obtained from FEMA, any modifications that were made, additional data that was collected, further modeling that was performed, and results. Additionally, this memo will contain the floodplain maps and a summary of the flood-prone properties and infrastructure identified within the study area.

Task 4 – Evaluation of Mitigation Alternatives

Identification of Mitigation Alternatives After establishing the baseline models, we will work with project partners and consult the existing all-hazard mitigation plan to identify goals and objectives for flood hazard mitigation. We will use these goals to guide the development of potential flood hazard mitigation alternatives relating to property protection, flood damage prevention and planning, natural resource protection, structural modifications, emergency services, pollution prevention, and public education and information. Potential mitigation alternatives may include actions intended to lower flood levels or frequency, reduce damage due to flooding, protect natural resources, reduce potential pollution, increase the ability of emergency services to continue operations during floods, or educate the public to be proactive in reducing the potential for flood damages and loss. We will explore all options deemed potentially feasible by project partners.

Evaluation of Structural Alternatives For the identified mitigation alternatives that would involve modification of the stream channel or floodplain, we will utilize the hydraulic models developed under Task 3 to evaluate impacts on flooding. Structural alternatives could include replacement or retrofits of bridges/culverts; removal or relocation of structures, buildings, or channel encroachments; channel/floodplain modifications; or floodplain improvements/reclamation. The evaluation will include at a minimum the high priority reaches and structures identified in the Background & Understanding section above. This analysis will involve modifying stream channel and/or structure geometry to reflect the proposed mitigation, re-running the baseline hydraulic models, and evaluating the impacts to flooding in the affected area.

Structure evaluations will focus on modeling a no-crossing condition without approaches for establishing a baseline condition, determining changes in flood water surface elevations in the impact area before and after mitigation, maximizing structure waterway openings given the limitations of existing physical features, determining required floodplain grading work to obtain optimum hydraulic capacity, evaluating the feasibility of installing any proposed new structures while maintaining traffic, identifying impacts on existing private and public infrastructure, and comparing cost benefits.

The evaluations may include, but not be limited to, the following considerations in each reach:

• Reductions in floodplain constrictions that may lead to lower flood elevations upstream • Bank stabilization measures • Flood protection measures to reduce flood levels and/or velocities at existing homes,

businesses, and other facilities • Floodplain reclamation • Solutions for reducing water surface elevations, velocities, and excessive sediment transport

along the corridors • Measures to reduce channel and bank erosion • Effectiveness and longevity of the channel banks and linings • Locations where structures could be removed or relocated or grading could be conducted to

facilitate the flow of flood waters

We will evaluate and summarize the potential for mitigation alternatives to reduce flood losses in terms of water surface elevations, inundation area, flooding depths, and flow velocities. Mitigation alternatives will be evaluated both separately and in combination as appropriate, where two alternatives can produce a combined effect. The results of the modeled mitigation alternatives will be compared to the results of


the baseline model through the use of comparative water surface plots, inundation maps, depth maps, and floodway velocity tables.

Evaluation of Non-Structural Alternatives In areas where flood hazard mitigation through structural measures may not feasible, non-structural mitigation alternatives will be evaluated. Non-structural measures are not intended to reduce flooding, but instead attempt to limit flood damage by protecting structures in flood-prone areas. We will evaluate whether non-structural measures such as flood proofing, structure relocation, flood insurance coverage, etc. could be employed in these areas to reduce the impacts of flooding on the community. Evaluation of non-structural measures will include an assessment of whether structures are likely to present a repetitive loss to inform whether they would be more appropriate to insure or relocate.

Feasibility Analysis We will evaluate mitigation alternatives to identify which alternatives may be feasible and should be further pursued. To support this analysis, we will identify potential impacts associated with each alternative, including the potential for downstream impacts caused by greater flood conveyance and the effect on sediment transport. We will also develop preliminary (budgetary level) opinions of probable construction costs (OPCCs) for each alternative, including any additional data collection, engineering, permitting, and construction. We will then weigh the potential benefits and mitigation goals achieved against the cost, regulatory requirements, and negative impacts of each mitigation alternative. We will identify any mitigation alternatives which are unlikely to provide acceptable benefit/cost ratios and therefore should no longer be pursued. We will recommend a subset of feasible alternatives for implementation. We will identify any future data collection, analysis, or design that may be needed to facilitate the further evaluation of recommended mitigation alternatives.

Technical Memos We will summarize the findings of the feasibility analysis in a technical memo for each study area describing the analysis, mitigation alternatives, and recommendations.

Deliverables • Hydraulic model input/output files (HEC-RAS & PDF) • Inundation mapping (GIS & PDF) • Technical memo for each study area (PDF)

Task 5 – Flood Engineering Analysis Report

Work completed under Tasks 1 through 4 will be summarized in a Flood Engineering Analysis Report for each phase to provide preliminary results of the feasibility analysis and recommendations for flood hazard mitigation alternatives to the communities. The report will include, but not be limited to, the information contained in the technical memos developed under Tasks 2 through 4. The report may include, but not be limited to, the following example table of contents:

• Introduction Project Background Community Involvement

• Existing Conditions Existing Information Watershed


Infrastructure Hydrology Water Quality Field Assessment

• Flood Hazards Flood History Summary of FEMA FIS Hydraulic Modeling of Baseline Conditions (incl. model output summary tables &

mapping) • Flood Mitigation Alternatives Analysis

Identification of Alternatives Evaluation of Alternatives (incl. model output summary tables & mapping) Impact Analysis Cost Opinions Feasibility Analysis

• Recommendations Recommended Mitigation Alternatives Implementation Plan Recommendations for Future Analysis

• References

Draft reports will be developed and circulated to project partners for review and comment (Word, PDF, and 8 paper copies for each study area as requested). The project director will then meet with project partners in each study area to present the draft report and solicit feedback. The presentations will provide a summary of the analyses performed, findings of the feasibility analysis, and the plan for implementation of recommended mitigation measures. Following the meetings, we will make revisions based on project partner comments and finalize the report. We will distribute 8 paper copies of each final report to project partners as requested.

Deliverables • Draft report (Word, PDF, & 8 paper copies for each study area as requested) • Preparation for and attendance at meeting with project partners • Final report (Word, PDF, & 8 paper copies for each study area as requested)

Task 6 – Local Flood Hazard Mitigation Feasibility Analysis & Plan

Under this task, we will explore in further detail the costs, benefits, and feasibility of each option from Task 5 determined by project partners to have a flood reduction or water quality benefit. This task will culminate with a plan for implementing the projects deemed by the communities to be viable.

Review of Municipal Regulations We will work with project partners to review the municipal regulations currently in place, particularly zoning and subdivision ordinances and flood damage prevention regulations. This review will focus on verifying that current regulations comply with the NFIP and will evaluate where modifications may be feasible.


Benefit Cost Analysis For each of the mitigation alternatives that were progressed from Task 5, we will utilize FEMA’s Benefit Cost Analysis (BCA) toolkit to evaluate the benefit/cost ratio (BCR) of the alternative. The BCA toolkit will be utilized in two ways, depending on the level of available data. For sites with sufficient available site-specific information (e.g., cost of response or repairs), the damage frequency assessment module will be utilized. In cases where insufficient site-specific information is available, the flood module will be utilized with default values.

Water Quality Benefit Analysis Each alternative will be evaluated to identify potential water quality benefits and provide a general enumeration scale of benefits considering the watershed, its status with respect to various pollutants, and the specific pollutants to be mitigated (e.g., number of structures mitigated, tons of eroded sediment mitigated, etc.).

Identification of Funding Sources We will identify potential funding sources for recommended mitigation alternatives with a favorable benefit cost analysis (i.e., greater than 1.0). Funding through FEMA’s various grant programs will be explored, and the most appropriate programs will be identified for each potential mitigation alternative, taking into consideration the level of available funding from each grant program at the time of the study. For mitigation alternatives that are unlikely to produce benefit cost ratios greater than 1.0 but may still be viable, we will explore alternative funding sources, including various US Army Corps of Engineers programs or FEMA’s Hazard Mitigation Grant Program (HMGP) under the “5% Initiative Project” class.

Implementation Plan Update We will incorporate the findings of the above analyses to update the recommended prioritization of mitigation alternatives and implementation plan developed in Task 5. Revisions will be based on the ability of proposed projects to be completed under existing municipal regulations, predicted benefit cost ratios, potential water quality benefits, and the availability of applicable funding sources. The project director will summarize the updates and present the findings in a meeting with project partners in each study area.

Local Flood Hazard Mitigation Plan Following review of the implementation plan updates by project partners, we will develop a Local Flood Hazard Mitigation Plan (LFHMP) to document the results of the above analyses. It is envisioned that the Flood Engineering Analysis Report developed in Task 5 will be updated and appended to as appropriate to produce the LFHMP. In addition to the example table of contents provided in Task 5, the LFHMP will address the adequacy of existing municipal regulations relative to flood prevention and protection, historic and potential sources of water quality impairment, available funding for identified mitigation alternatives, an updated plan for prioritizing and implementing recommended mitigation alternatives, and updated recommendations for future analysis (including hydrologic and/or two-dimensional hydraulic modeling). Previously included maps of inundation and flood-prone areas as well as the reference list will be updated as needed.

A draft plan will be developed and circulated to project partners for review and comment (Word, PDF, and 8 paper copies for each study area as requested). We will then incorporate one round of comments and finalize the plan. We will distribute 8 paper copies of each final report to project partners as requested.

Appendix A: Relevant Project Experience The following selected projects demonstrate the experience of our team in areas relevant to the proposed project.

Flood Studies & Hazard Mitigation Planning

Lyndon Flood Hazard Assessment & Mitigation Evaluation Jamie Caplan Consulting for the NE VT Development Assoc. (Lyndon, VT) / Status: complete Gomez and Sullivan conducted a flood hazard assessment and mitigation evaluation in support of a Multi-Jurisdictional Hazard Mitigation Plan being developed for the Town of Lyndon and Village of Lyndonville, VT. The purpose of mitigation planning is to identify policies and actions that can be implemented over the long term to reduce risk and future losses. Local governments are required to develop a hazard mitigation plan approved by the Federal Emergency Management Agency (FEMA) as a condition for receiving FEMA Hazard Mitigation Grant Program (HMGP) and Pre-Disaster Mitigation (PDM) grants. Gomez and Sullivan’s responsibilities included data collection and analysis, identification of potential flood hazards, profiling and mapping of flood hazard areas, inventory of community assets within mapped flood hazard areas, vulnerability assessment of at-risk assets, recommendation of flood mitigation projects, and documentation of findings in a report. The plan was developed in accordance with FEMA’s Local Mitigation Planning Handbook.

Passumpsic River Flood Study Town of Lyndon, VT / Status: complete Considerable flood events had occurred over recent years within the Town of Lyndon, resulting in considerable property damage, power interruptions, traffic interruptions, and disruption to residents and businesses in the area. Gomez and Sullivan was retained by the Town to assist with sorting out varying advice given by prior flood study efforts. Services included a review of past findings, an independent hydraulic analysis of the Passumpsic River, and the identification of causes and sources of flooding within the Town. Gomez and Sullivan developed a HEC-RAS hydraulic model to evaluate the potential reduction in flooding due to a) removal of bridges, b) widening bridges, c) removal of the Vail Dam, and/or d) dredging of sediments. As part of the alternatives analysis, Phase 2 geomorphic assessments were analyzed and a disconnect between the river and its floodplain was identified upstream of Lyndon. Recommendations were made to protect existing undeveloped floodplains and to consider methods to reactive available floodplains. A report including floodplain inundation maps was delivered to the Town.


Marcy Stormwater Management Plan Town of Marcy, NY / Status: complete Gomez and Sullivan developed a town-wide stormwater management plan for the town of Marcy, NY. The project included an inventory and analysis of existing stormwater culverts, collection of data for 20 new or improved culverts, an inspection and assessment of two existing storm water retention basins, and an analysis of current and potential flood areas. Seven HEC-HMS hydrologic models were developed to identify potential flooding problem areas within the town. The project resulted in an evaluation of the current town stormwater guidelines and recommendations for a revised stormwater management policy. The town later contracted with Gomez and Sullivan again to investigate management options, including regional detention, hydraulic efficiency improvements, and off-channel storage. Also conducted an alternatives analysis and provided design services and contract documents for the construction of a 48-inch diameter railroad culvert and other drainage improvements to alleviate flooding conditions. Studied several construction methods and improvements including a bored and jacked crossing of railroad, realignment of road crossings, high flow diversions, and open channel improvements.

Flood Warning and Operations System New York State Canal Corporation (Albany, NY) / Status: ongoing The New York State Canal Corporation is currently in the process of implementing a Flood Warning and Operations System (FWOS) which involves the development of hydrologic and hydraulic models for the Mohawk, Upper Hudson, and Oswego River Watersheds. Gomez and Sullivan is part of the consulting team tasked with converting existing HEC-RAS hydraulic models into the Danish Institute of Hydrology (DHI) MIKE 11 software and calibrating the models to historic events. To date, Gomez and Sullivan has modeled more than 260 miles in the target watersheds. This work has included incorporating survey data and modeling bridges, dams, and reservoirs, as well as holding site visits and meetings with operators at the modeled projects (locks, hydroelectric projects, and reservoir storage projects) to gain an understanding of standard operating procedures and to obtain structural information for hydraulic modeling. The dynamic real-time inundation mapping will be provided through a GIS-based interactive mapping system using orthoimagery to illustrate event-based flood forecasted water levels, timing of peak water levels, and projected flood inundation areas throughout the three watersheds. This will include identification of areas of interest (AOI), maximum flood flows at each AOI, and historic high-water marks, as well as development of a real-time map for each AOI. The finalized FWOS will provide more accurate and timely flood forecasts than the current system, and is intended to notify of projected flood conditions on a near real-time basis.

East Branch Delaware River Basin Flood Insurance Study Federal Emergency Management Agency (Delaware & Ulster Co., NY) / Status: complete Gomez and Sullivan was sub-contracted as part of the Risk Assessment, Mapping, and Planning Partners (RAMPP) team to perform hydrologic analyses, hydraulic modeling, and floodplain mapping in support of Digital Flood Insurance Rate Map (DFIRM) development for portions of Delaware and Ulster Counties, NY, including the communities of Fleischmanns, Middletown, Roxbury, Margaretville, and Hardenburgh. Field reconnaissance was conducted for approximately 37 miles of detailed and lake studies and 12 miles


of limited detailed streams to observe floodplain features, collect information on hydraulic and/or flood-control structures, and assist in the placement of cross-sections to be surveyed. Hydrologic analyses were conducted for 15 streams, including two impounded lakes and approximately 58 stream-miles. Stream segment flow nominations were developed for approximately 130 locations to represent the hydrology. HEC-RAS hydraulic models were developed for each of the detailed (37 miles), limited detailed (12 miles) and approximate (9 miles) study reaches, using HEC-GeoRAS and other GIS-based tools. Hydraulic cross-sections were obtained from the Light Detection and Ranging (LiDAR) based terrain model as well survey data. Floodway data tables and flood profiles were prepared for new detailed stream reaches. GIS-based map layers representing flood inundation areas, hydraulic model features (centerlines, cross sections, and structures), model results, and hydrology nominations were developed for all studies.

Albany County Flood Insurance Study NYS Dept. of Environmental Cons. (Albany Co., NY) / Status: complete Gomez and Sullivan was retained by the NYS DEC as the prime on a team to develop DFIRMs for Albany County, NY. Field reconnaissance and ground survey were conducted on approximately 25 miles of detailed and 23 miles of limited detailed stream. Over 325 cross-sections and 70 structures were selected for survey. Stream channel survey data was incorporated into a LiDAR-based digital elevation model (DEM) of the county. Hydrologic analyses were conducted for 73 streams and over 180 stream-miles. Stream segment flow nominations were developed for over 250 locations. HEC-RAS hydraulic models were developed for over 186 miles of stream, and the remaining 130 miles of stream were redelineated using effective flood elevation profiles. Floodway data tables, flood profiles, and DFIRMs were developed for flooding sources in 19 communities. A total of 128 map panels were developed for the DFIRMs along with the FIS in the new county-wide format. Gomez and Sullivan was also responsible for working with the NYS DEC in the post-preliminary phase, including attending final community coordination meetings, publishing base flood elevation (BFE) notices, and issuing BFE determination letters and Letters of Final Determination.

Ulster County Flood Insurance Study NYS Dept. of Environmental Conservation (Ulster Co., NY) / Status: complete Gomez and Sullivan was retained by the NYS DEC as the prime on a team to develop DFIRMs for portions of Ulster County outside the NYC watershed. Field reconnaissance and ground survey was conducted on approximately 29 miles of stream, including over 200 cross-sections and structures. Stream channel survey data was incorporated into a LiDAR-based DEM of the county. Hydrologic analyses were conducted for 96 streams and over 450 stream-miles. Stream segment flow nominations were developed for over 150 locations. HEC-RAS hydraulic were developed for over 280 miles of stream, and the remaining stream reaches were redelineated using effective flood elevation profiles. Floodway data tables, flood profiles, and DFIRMs were developed for flooding sources in 17 communities. Gomez and Sullivan worked with the NYS DEC in attending community coordination meetings, publishing BFE notices, issuing BFE determination letters, and other post-preliminary steps toward final map adoption. A total of 54 preliminary FIRMs and an FIS Report were issued in the new county-wide format.


Batten Kill & Roaring Branch Restoration Analysis Batten Kill Watershed Alliance (Arlington, VT) / Status: complete As a follow-up to Phase 1 and Phase 2 geomorphic assessments of the Batten Kill and its tributaries, Gomez and Sullivan evaluated restoration alternatives for the lower reach of the Roaring Branch just upstream of its confluence with the river in Arlington, VT. Historic dredging and berming along the lower Roaring Branch had disconnected the stream from its floodplain, resulting in excessive in-channel energy and erosion. To evaluate the effects of partially or completely removing one or more berms, Gomez and Sullivan developed a HEC-GeoRAS hydraulic model to estimate inundation for various flood events with and without the berms. The study results demonstrated that removal of the berms could help dissipate in-stream energy and reduce erosion. A portion of the berms was successfully removed, which has led to a reduction of bank erosion at the site.

Walloomsac River Phase 2 Geomorphic Assessment and Channel Management Plan Bennington County Conservation District (Bennington, VT) / Status: complete Gomez and Sullivan conducted a Phase 2 geomorphic assessment of the Walloomsac River and Roaring Branch in Bennington, VT. Previous flooding throughout the town has resulted in the implementation of significant flood protection measures along both rivers. To address these conditions, Phase 2 fieldwork was conducted along 11.3 miles of river, involving collecting information about channel dimensions, shoreline and riparian conditions, floodplain encroachments and modifications, and bottom substrate. The data collected during this assessment allowed for an understanding of how historic and current land and channel management activities have affected the river’s geomorphic condition. The results of the geomorphic assessment were used to develop a channel management and river corridor protection plan, which included mitigation alternatives to reduce the risks associated with flooding and fluvial erosion hazards. To further understanding of this watershed, Gomez and Sullivan was subsequently contracted to conduct Phase 2 geomorphic assessments of City Stream (4 reaches) and Bolles Brook (2 reaches) upstream in Woodford, VT, which join to form the Roaring Branch.

Design/Permitting of Stream Channel & Floodplain Improvements

Little Beaver Island Wetland Restoration New York Power Authority (Grand Island, NY) / Status: post-construction monitoring Gomez and Sullivan designed the Little Beaver Island Habitat Improvement Project as part of implementation of the Niagara Power Project license. The purpose of the project was to restore 8.5 acres of hemi-marsh that were removed several decades ago during cut and fill operations related to park improvements. While primarily a wetland restoration, other features added through the collaborative process for recreation and as a means to dispose of 74,000 CY of excavated fill included a canoe/kayak launch, osprey pole, shallow breakwaters and shoreline stabilization, sledding hill, walking trail, overlook, and green parking lot. Restoration involved removal of several feet of fill, grading to ensure connectivity with adjacent wetlands and open water and to create complex micro-topography, placement of marsh topsoil, shoreline stabilization utilizing bio-engineering techniques, invasive species control, and native plantings. The project required extensive agency consultation, collaboration, and permitting, including NYSDOS Coastal Zone Management and USACE 404 wetland permits and a stormwater pollution prevention plan (under


the SPDES permit). Gomez and Sullivan developed engineering design plans, technical specifications, and bid documents, provided construction oversight, and is conducting post-construction monitoring. The project won the National Hydropower Association's Outstanding Stewards of America's Waters Award.

Weir River Smelt Habitat Restoration Design & Permitting Massachusetts Division of Marine Fisheries (Hingham, MA) / Status: complete Gomez and Sullivan designed a small island in the Weir River downstream of the Foundry Pond Dam to restore important rainbow smelt spawning habitat. A HEC-RAS hydraulic model was developed to evaluate various island sizes/shapes with the goal of achieving target smelt spawning water depths and velocities. The model results were used to determine necessary size and placement details for stone riprap protection and other materials used to build the island, stabilize the banks, and restore the channel spawning substrate. Gomez and Sullivan prepared engineering design plans including materials specifications, a planting plan, and construction details. Gomez and Sullivan assisted with permit applications under a subsequent contract. The restoration was constructed and has been successful according to preliminary monitoring results.

Spicket River Bridge Replacement Hydrologic/Hydraulic Design Town of Salem, NH / Status: complete Gomez and Sullivan conducted a hydrologic and hydraulic analysis of the Spicket River to facilitate design of the 40-foot-wide Town Farm Road Bridge replacement in Salem, NH due to flooding issues. The detailed hydrologic analysis involved a comparison of flood frequency data computed by various means, including log-Pearson type III analyses of peak flow data at two gages, USGS reports for the 2006 and 2007 floods in NH (which used 1978 regression equations), updated 2008 USGS regression equations (StreamStats), a weighted average of the log-Pearson analysis at the gage and StreamStats, FHWA 5- and 7-parameter regression equations, NH DOT regression equations (NEHL method), as well as the 1977 FIS. A HEC-GeoRAS hydraulic model was developed using existing FIS cross-sections as well as updated topography from a survey, and was calibrated using records from a May 2006 flood.


Sediment Transport & Scour Analyses & Two-Dimensional Hydraulic Modeling

Three Rivers Confluence Two-Dimensional Sediment Analysis Riverlife (Pittsburgh, PA) / Status: complete Gomez and Sullivan developed both one and two-dimensional hydraulic models near the “Three Rivers” confluence in Pittsburgh, PA, where the Allegheny River and Monongahela River converge to create the Ohio River, using HEC-RAS and River2D, respectively. These models were developed for the purposes of evaluating sediment transport within the confluence. The two-dimensional hydraulic model was ultimately chosen to estimate the sediment competence and deposition potential for a proposed habitat-enhancement lagoon along the river’s north bank, where sediment deposition has been an issue during past high-flow events. Three potential lagoon design alternatives were analyzed using River2D, the hydraulic modeling software chosen for this study. Two-dimensional maps were created identifying areas of potential deposition, along with the expected particle size, within the three proposed lagoon designs.

McLane and Goldman Dams Sediment Transport & Scour Analysis Town of Milford, NH / Status: complete Gomez and Sullivan conducted a feasibility study to remove two dams separated by approximately 1,300 feet in downtown Milford, NH on the Souhegan River. Among many other tasks, responsibilities included obtaining survey and bathymetric data and developing a HEC-RAS hydraulic model of the project area extending well upstream of the impoundment and well below the dam, including bridges. The model was used to simulate depth and velocities within the impoundment with the dam in place and with the dam/sediment removed, as well as to predict the geomorphic response of the project area above and below the dam by conducting a sediment transport analysis and analyzing scour potential at bridges. The results were used to estimate the volume of sediment expected to mobilize under the 100-year flood and a recent flood event in both the existing conditions and dam removal scenarios.

Northfield Mountain Pumped Storage Project Fish Passage Study (2-D Model) FirstLight Power Resources (Northfield, MA) / Status: complete As part of the FERC relicensing process for the Northfield Mountain Pumped Storage Project, Gomez and Sullivan is conducting a study to evaluate the effect of project operations on fish passage in the Connecticut River. Work involved public presentation of the study plan, field collection of bathymetric and water column velocity data, development and calibration of a two-dimensional (2-D) hydraulic model, and preparation of a report. The 2-D model was developed using River2D for a 10-kilometer portion of the Project’s lower pool, which is also the impoundment for FirstLight’s Turners Falls Hydroelectric Project further downstream on the Connecticut River. A total of 40 different scenarios were run, which altered the baseflow in the river, Northfield operations, and Turners Falls operations. The results of the model were used to evaluate the potential impact of Project operations on upstream migration of adult shad and downstream migration of juvenile shad due to flow reversals, velocity barriers, undesirable attraction flows, and entrainment/impingement on the trashrack structure.
