Stormwater runoff from Hurricane Irene (August 2011) and

Tropical Storm Lee (September 2011) caused significant

damage to portions of the White Creek stream corridor in both

the Town and Village of Salem, NY. C.T. Male was tasked with

preparing a Project Work Plan that would provide technical

support for a grant application that was being prepared and

submitted by Washington County. This application would aid in

securing funds to restore White Creek to Pre-Hurricane and

Tropical Storm Lee conditions.

There were three (3) principal impacts that these storms had on

the White Creek stream corridor, including flooding, gravel

deposition and streambank erosion. There were four (4) main

impacted areas, which were further broken up into specific

work areas. The current condition of each of these areas was

described in the Project Work Plan for DEC/ESD Grant

Application, along with mitigation and restoration

recommendations for each work area. C.T. Male also prepared

cost estimates for each area, which were included in the

Project Work Plan.

On July 13, 2012, correspondence from the NYS Department of

Economic Development was received, stating that the Project

had been awarded funding.

The most recent published Flood Insurance Study (FIS) for

Schoharie County has an effective date of February 16, 2012.

The associated Flood Insurance Rate Map (FIRM) for the project

area has an effective date of April 2, 2004. This map shows that

most of the proposed senior housing development is located in

a “Zone AE” (a.k.a. within the100-year floodplain) associated

with the Schoharie Creek.

The existing site is generally at elevation 610 feet or below, and

the 1%-annual-chance (a.k.a. 100-year) base flood elevation at

this location, as presented on the FIRM, is at approximately 611

feet. The site development plans called for a portion of the site

to be filled to elevation 612 feet, or higher. C.T. Male Associates

was retained to evaluate the potential effect of this fill on the

base flood elevation and flow velocities within the Schoharie

Creek floodplain.

The HEC-RAS (software package produced by the U.S. Army

Corps of Engineers) model, which was used by FEMA in the

preparation of the FIS and FIRM for the Schoharie Creek, was

obtained from the NYSDEC. The model was revised to include

obstructions, which simulated the planned placement of the fill.

As a result of this modeling, it was determined that the water

surface elevations remained relatively unchanged; therefore, it

was determined that the filling of portions of the site would not

negatively impact adjoining or surrounding property.

C.T. Male prepared a Hydrology and Hydraulics (H&H) report,

which described the results of the modeling/analysis, as well as

the conclusions that were arrived at.

Hydraulic Analysis of Schoharie Creek Village of Schoharie, New York




The Ten Mile River flows from north to south through the Hamlet

of Dover Plains, in the Town of Dover, Dutchess County, New

York. In 2008 FEMA released a preliminary version of a re-study

of the Ten Mile River for public comments. The owners of the

Powell Mobile Home Park opted to submit an appeal during the

public comment period, as they felt that the re-study did not

accurately represent the river as it passes by their property. CT

Male was retained to perform the hydraulic modeling work, and

to assess the hydraulic characteristics of the river in the vicinity

of the Park.

CT Male prepared a new HEC-RAS model based on the FEMA’s

preliminary model, but incorporating new cross-sections to

better define this segment of the river. This new model was

based upon FEMA’s existing cross-sections and additional cross-

sections prepared based on actual field survey data.

The new model was run to determine the appropriate locations

of the 1% annual chance floodplain and floodway boundaries.

CT Male prepared the documentation to accompany a Letter

of Map Revision request to FEMA.

In September 2008, CT Male Associates was retained by the

Saratoga Lake Association to conduct a hydraulic analysis of

Fish Creek, the lake’s outlet. The study was prompted by

frequent complaints to the SLA about lake levels being either

too high or too low. The purpose of the study was to develop a

better understanding of the hydraulics of Fish Creek and to

provide insight into possible improved water level management

of Saratoga Lake.

A profile of the creek bottom in the deepest part of the channel

was obtained using a calibrated fathometer attached to the

stern of a motorized boat. The unit was also connected to GPS

equipment so that the surveyors were able to simultaneously

record location and elevation of the unit and the elevation of

the creek bottom at a periodic, preset time interval. Cross-

section data was also obtained along the length of the study

area.

CT Male performed a detailed hydraulic analysis of the Fish

Creek using a combination of HEC-RAS and TR-20 software.

The model was calibrated to match observed high-flow

conditions, and was used to develop improved flow

management guidelines for the benefit of Saratoga Lake

residents.

Entity Statement

Entity Statement

a) C.T. Male Associates Engineering, Surveying, Architecture & Landscape Architecture,

D.P.C. (C.T. Male) is a single firm.

b) C.T. Male has approximately 120 employees and offers services in the fields of

Engineering, Building Systems, Energy, Environmental, Surveying and Land Information

Services. The firm's headquarters is located in Latham, New York with branch offices in

Glens Falls, Highland, Johnstown, Red Hook, and Syracuse, New York and

Mechanicsburg, Pennsylvania.

Proposed Technical Approach

C.T. Male

Technical Approach

It is CTMA’s understanding that the project will consist of two phases: Phase 1 will consist of the

Village of Tannersville study area, and Phase 2 will consist of the Village of Hunter and Town of

Hunter study area.

The Village of Tannersville study area will consists of the Gooseberry Creek from its headwaters to

a point immediately downstream of the Tannersville wastewater treatment facility, as well as the

lower portions of its two major tributaries the Sawmill Creek and Allen Brook. All three of these

streams flow from north to south through the Village and across Route 23A, before turning to the

west through the southern portion of the Village.

The Village/Town of Hunter study area primarily consists of the Schoharie Creek as it flows from

west to east through the Town and Village, as well as the lower portion of its tributaries. These

include the Gooseberry Creek below the stopping point of the Tannersville study area.

A CT Male hydraulic engineer visited both study areas on November 14, 2016, and provided the

following observations:

Tannersville Study Area Lake Rip Van Winkle outlet works. The outlet works could be modified to provide some storm-day detention in the lake, reducing flood flows in the Gooseberry Creek. Similar measures could potentially be taken at smaller wetlands located farther upstream along the Gooseberry Creek.

C.T. Male -2-

Technical Approach

Tannersville Study Area Sawmill Creek, immediately upstream of the Railroad Avenue culvert, facing upstream. Buildings located adjacent to the stream are at high risk of flooding if the nearby culvert backs up.

Tannersville Study Area Sawmill Creek culvert under Route 23A, facing downstream. A backup at this culvert could cause significant damage to downtown Tannersville properties.

Hunter Study Area Deming Road Bridge, facing downstream. There are six bridges across the Schoharie Creek within the study area. These bridges may exacerbate the flooding in upstream areas.

C.T. Male -3-

Technical Approach

Hunter Study Area Schoharie Creek, facing upstream from Deming Road Bridge. Route 23A (at left in picture) runs within the stream’s 100-year floodplain for approximately 2 miles. Side streams entering the Schoharie Creek from the north may cause localized flooding , in particular at culvert crossings under Route 23A.

Hunter Study Area Schoharie Creek, facing upstream from the Bridge Street bridge. Properties along the north bank of the stream have been built up and reinforced with rock armoring, as seen along the left side of the picture. Several low lying areas within the study areas may be prone to flooding. The project will include identifying these areas, and developing recommendations for reducing the risk of damage to private property and critical infrastructure.

Hunter Study Area Schoharie Creek, facing downstream, from Riverside Drive. Note the sediment/gravel accumulation in this section of the stream, which can impact the stream’s ability to safely convey flood flows.

C.T. Male -4-

Technical Approach

For each of the two phases described above, the following tasks are proposed:

PART I – FLOOD ENGINEERING ANALYSIS

Task 1: Project Management, Coordination, and Meetings

The objective of this task is to provide support and guidance to the Village of Tannersville, the

Village of Hunter, and the Town of Hunter (hereinafter referred to as the Hunter Corridor

Municipalities) and the Flood Advisory Committee with respect to the development of the

analyses and reports described in this proposal. This task will be on-going throughout the

duration of the project. This task will include the following work scope:

1. On an as-needed basis, prepare educational materials such as maps, posters, and

handouts. These will be customized for the intended audience (i.e. technical or non-

technical).

2. Prepare for and attend meetings. This scope includes attendance at up to two formal

public information meetings, four Town/Village Board meetings, and three Flood Advisory

Committee meetings (if applicable). For all meetings, CTMA will prepare and circulate

meeting minutes for review and acceptance by the Town/Village Board.

3. Provide bi-weekly written progress reports to the Town/Village Board. These reports will

include a summary of work performed and billing to date broken down by Task, as well

as a tentative schedule for upcoming work and deliverables.

4. Maintain and organize a library of all documents, maps, digital models, survey records,

etc, gathered and/or generated during the course of the project. This library will be

maintained in an editable digital format for all files received as such, or as PDFs for all

documents received on paper. The complete library will be turned over to the

Town/Village on CD or other digital media upon project completion.

5. Prepare and provide a record of time spent on each task as required by the LFA grant

funding agreement.

C.T. Male -5-

Technical Approach

Task 2: Data Collection and Field Verification

The purpose of this task is to gather background information on the Schoharie Creek and its

tributaries in the vicinity of the study areas as identified on the Maps in the RFP. This task involves

generating general purpose base mapping, and will include the following work scope:

1. Gather, compile, and review all available and relevant data pertaining to the subject

streams and the associated floodplains. At a minimum, this will include the items listed in

Section III.B.2.1 of the RFP.

2. Compile a list of resource material from Task 2.1.

3. Conduct a visual assessment of the stream corridors and floodplains, accompanied by

GCSWCD and/or Town and Village officials. The purpose of the drive/walkthrough will be

to identify and document all significant hydraulic features, as well as to identify areas of

historic flooding. Note that this scope does not include any survey services. Any

recommendations for survey services will be included in the Flood Engineering Analysis

Report prepared under Task 5, for consideration by the Town/Village Board and the

GCSWCD.

4. Perform watershed delineations for each of the above referenced stream reaches, and

all significant tributaries thereto, based on USGS Topographic Quadrangle Maps. CTMA

will perform a cursory field review of the watershed boundaries and site conditions in the

watershed to make the flow estimates as accurate as possible.

5. To the extent practical, enter all geographic data into base maps in AutoCAD format.

At a minimum, these base maps will include orthoimagery, USGS topography, USGS soils

data, FEMA flood mapping, and County tax maps. These maps will provide the basis for

any exhibits prepared as part of other tasks.

6. Identify possible sources of contamination in the watershed and document known

impacts to water quality as a result of flooding.

C.T. Male -6-

Technical Approach

7. Prepare a technical memorandum describing the nature, quality, and relevance of the

data gathered under this task. The memorandum will include a comprehensive list of the

data gathered, and will identify any “gaps” in the collected data.

Task 3: Hydraulic Modeling Baseline

The primary objective of this task is to develop working and properly geo-referenced HEC-RAS

models for each of the three (3) subject stream reaches. These models will be the basis for the

evaluation of mitigation alternatives to be performed in Task 4. This task will include the following

work scope:

1. Obtain the HEC-RAS files associated with the 2015 FEMA FIS for Greene County. It is

anticipated that these files will be available from the NYSDEC or Greene County. If

necessary, the files may be obtained directly from FEMA (or from the technical

consultant that performed the modeling), though this may result in delays to the

completion of this Task. The model obtained will be considered the “Effective Model”.

2. The HEC-RAS files thus obtained will be checked for completeness, and run on CTMA

computers to ensure that the published FIS results can be reproduced. The resulting

model will be considered the “Duplicate Effective Model”.

3. If significant discrepancies are noted between the Duplicate Effective Model and

observed field conditions, the model may be modified to reflect the on-the-ground

conditions. If this is the case, the revised model will be known as the “Corrected Effective

Model”, and it will replace the Duplicate Effective Model as the basis for subsequent

Tasks. Note that this scope does not include the preparation of any map revision

requests to FEMA. The gathering of additional survey or topographic information is not

included in this task.

4. Run the Duplicate Effective Model for the 2-, 10-, 25- ,50-, 100- and 500-year flow

conditions.

C.T. Male -7-

Technical Approach

5. The actual HEC-RAS cross-sections will be converted into the AutoCAD format, allowing

them to be shown on exhibits and plans. These maps will include available GIS and

FEMA data and present the existing floodplains on available LIDAR based DEM or GIS

mapping of the stream reaches on the most recent available aerial imagery.

This task includes identifying and mapping of flood prone areas and infrastructure.

6. Prepare a technical memorandum describing the processing and modifications (if any)

performed to the HEC-RAS files. The memorandum will include digital copies of all of the

HEC-RAS models developed as part of this task.

Task 4: Evaluate Mitigation Alternatives

The primary objective of this task is to evaluate possible flood hazard mitigation options which

the Town/Village, Flood Advisory Committee, and GCSWCD could explore. This task will include

the following work scope items:

1. Coordinate with the Town/Village Board to develop a list of possible mitigation

alternatives in each of seven categories, as described in Section III.B.4.1 of the RFP.

2. Evaluate the effectiveness of possible structural projects by developing a series of

proposed conditions HEC-RAS models. The list of structural actions to be evaluated will

be reviewed and approved by the Town/Village Board. At this time it is anticipated that

up to fifteen (15) scenarios will be considered (five (5) at each of the three (3) study

reaches), with each scenario incorporating one or more structural actions. For each

scenario, the appropriate HEC-RAS simulation for the 2-, 10-, 25-, 50-, 100-, and 500-year

flow conditions will be run; and prepare water surface elevation profiles and inundation

mapping for easy comparison with both existing conditions and other possible mitigation

scenarios. The evaluation will include, at a minimum, all of the high priority elements

described in Section III.B.4.2 of the RFP.

C.T. Male -8-

Technical Approach

3. Evaluate the feasibility, regulatory requirements, benefits, and potential impacts

(including sediment transport) of each of the mitigation alternatives explored under this

task. CTMA will also develop preliminary opinions of probable

implementation/construction costs for each alternative.

4. Consult with the local hazard mitigation plan as it relates to bridge replacement, retrofits

of bridges or culverts, removal/relocation of structures and buildings.

5. Assess the statistical flood events that such mitigation alternatives protect against.

6. Prepare a technical memorandum summarizing the evaluation of alternatives performed

under this task. The memorandum will include recommendations for the selection of

alternatives, and for additional analysis, if required. The memorandum will also include all

applicable inundation mapping and digital copies of all HEC-RAS models developed as

part of this task and preliminary opinions of probable construction costs for mitigation

alternatives.

Task 5: Flood Engineering Analysis Report

The objective of this task is to develop a Flood Engineering Analysis Report, which will document

the findings, results, and recommendations associated with Tasks 1 through 4. This task will

include the following work scope:

1. Prepare a draft Flood Mitigation Plan/Flood Engineering Report, which will generally

include all of the elements presented in Section III.B.5.1 of the RFP. Both paper and

electronic versions (as needed) of the draft report will be provided to the Town/Village

Board for review.

2. Assist the Town/Village Board in reviewing the draft document, and in selecting projects

for further analysis and development. This process will include preparation for and

attendance at two (2) Town/Village Board meetings.

3. Based on the Town/Village Board review, prepare a final version of the Flood Engineering

Analysis Report. This report will include the final recommendations of flood mitigation

projects to pursue. Provide up to ten (10) paper copies of the final report, as well as two

digital copies (in PDF format) on CD. The digital copies will also include all HEC-RAS and

other modeling files generated under Tasks 3 and 4.

PART II – FEASIBILITY ANALYSIS

Task 6: Local Flood Hazard Mitigation Feasibility Analysis and Plan

The objective of this task is to develop a Local Flood Hazard Mitigation Plan (LFHMP), which will

include final recommendations for the execution of mitigation measures. In general terms, the

LFHMP will take the recommendations included in the Engineering Analysis prepared under Task

5, review them for relative benefit, feasibility, and potential funding opportunities, sort them by

priority, and provide final recommendations for implementation. This task will include the

following work scope:

1. Review local laws and regulations (including zoning, subdivision of land, floodplain

management, and emergency services) for compatibility with current FEMA regulations.

2. For those flood hazard mitigation measures which were identified in the Flood

Engineering Analysis Report as having flood reduction or water quality benefits, the

following scope items will be performed:

Use the FEMA BCA software package to calculate the benefit/cost ratio of each

measure. This will include the development of budget level construction cost

estimates. If needed, we will consult with AE Knapp Associates in completing this

task.

Evaluate and quantify any potential water quality benefits.

For recommendations with a potential benefit/cost ratio of greater than 1.0,

evaluate likely funding opportunities, including but not limited to: Pre-Disaster

Mitigation (PDM), Hazard Mitigation Grant Program (HMGP), Flood Mitigation

Assistance (FMA), Repetitive Flood Claims (RFC), Severe Repetitive Loss (SRL),

Technical Approach

Stream Management Implementation Program, and CWC Flood Hazard

Mitigation Implementation Program. Note that this scope does not include the

preparation of grant or other funding applications. For benefit cost/ratios less

than 1.0 identify relevant funding sources such as those identified in Section

III.B.6.4 of the RFP.

3. Prepare a draft Local Flood Hazard Mitigation Plan, which will summarize the work

performed under this Task, and include a plan for implementation and prioritization of

mitigation options. This plan will identify the necessary permits/approvals that need to be

obtained prior to undertaking the work. Possible approvals/permits may need to be

obtained from the NYCDEP (water quality impacts to downstream Reservoir), the NYSDEC

(for any work in or adjacent to regulated water bodies), USACOE (for federally regulated

wetland impacts), Greene County (work within County rights of way) and NYSDOT (work

within NYS rights of way). Additionally, the Town/Village floodplain administrator will

need to review, and if acceptable, accept changes to the floodplain as a result of

making the proposed improvements. If required, a request may need to be made to

FEMA for a Letter of Map Amendment (LOMA) or a Letter of Map Revision (LOMR). CTMA

has a successful track record of securing these letters for similar type projects.

Provide both paper and electronic versions (as needed) of the draft report to the

Town/Village Board for review.

4. Based on the Town/Village Board review, prepare a final version of the Local Flood

Hazard Mitigation Plan. CTMA will provide up to 10 paper copies of the final plan, as well

as two digital copies (in PDF format) on CD.

Notes:

1. The range of dates for Task 2 has been extended to include warmer months. This is

because certain field operations may not be possible during the winter months due to

snow cover and ice in the streams.

2. The overlap between Tasks 2 and 3 is intended to allow the opportunity for field crews to

gather additional data, should the need for such data be revealed only during the

performance of the Task 3.
