An Intermunicipal

Floodplain Overlay

District was defined as a

high-priority action item.

http://www.gflrpc.org/floodsmartactionplan.html

The Flood Smart Approach

• Watershed approach

to floodplain

management

• Systematic decision-

making

• Community-specific

assessments

• Follow-up evaluation

of success

Why develop anintermunicipal floodplain local law?

✓New York’s Great Lakes Basin Interim

Action Plan (July 2014)

✓NYS 2100 Commission report

✓New York State Community Risk and

Resiliency Act (CRRA)

No Adverse Impact

Consolidated Laws

✓Recognized under New York General Municipal Law §119-u,

“Intermunicipal cooperation in comprehensive planning and

land use regulation”

✓Under §119-u 4., intermunicipal agreements can be used to

(e) “create an intermunicipal overlay district for the purpose

of protecting, enhancing, or developing community

resources that encompass two or more municipalities”

The Process

1. Established the Steering Committee

2. Developed a survey to determine minimum

standards and discussed how to define the

local floodplain

3. Site Plan Review Checklist

4. County Review Authority

5. Explore opportunities for simplified Floodplain

Development Permit Application

6. Finalization of the Model Intermunicipal

Floodplain Overlay District Local Law with

permit application and site plan checklist

development

7. Webinar presentation

The Products: Model Local Law

Article I: Purpose and Intent

Article II: Definitions

Article III: Applicability/District

Standards

Article IV: Actions for Referral

Article V: Referral Process

http://www.gflrpc.org/uploads/5/0/4/0/50406319/ifodlocallaw_final071818.pdf

Article III: Applicability/District Standards

1.High resolution mapping – representation of flood

inundation

– generally include a relationship between precipitation and discharge (cfs),

and between discharge and the flow of water over land and down the

channel.

– Data intensive and often expensive

2.Less rigorous mapping – represent lands that are likely

elevationally connected to the channel.

– Elevation, cost distances as a proxy for where water might flow if it

exceeds the channel

– Can be processing intensive but comparatively inexpensive

3.Setbacks – represent a measured distance from the

stream channel

– Example – some distance from top of bank or stream center line

Article III: Applicability/District Standards

• Flood Insurance Rate Maps (FIRMS)

• Drainage studies

• Proprietary models (ex. FATHOM)

• Publicly available model outputs or

In order to protect the stream corridor and prevent contaminants from entering the stream, consider the following:

• Maintain a healthy, vegetated streamside buffer by preserving trees and shrubs along the stream edge.

• Limit logging to removing large branches that fall into the stream and divert streamflow and cause erosion.

• Mitigate potential flood impacts on downstream properties.

• Control water flow through the streamside buffer to filter contaminants and reduce erosion.

• Reduce erosion by managing stormwater runoff to prevent channelized flow.

• Minimize impervious areas near the streamside by using stone or brick insteadof pavement for driveways and walkways.

• Exclude vehicles, livestock, or excessive pedestrian traffic.

• Reduce or eliminate buffer area exposure to fertilizer, herbicides, pesticide, animal waste, household and automotive chemicals, trash, debris, and piles of leaf litter.

• Maintain septic systems.

Lessons Learned?1. Internal support for adoption of an intermunicipal overlay district?

– Upstream/Downstream connections

– Consistent application = better for development across the County and solves watershed-level floodplain management.

– Having an existing work group, like a stormwater coalition.

2. Underutilized tool = Floodplain development permit application.Regardless of whether your municipality has zoning, you need to be issuing floodplain development permits if you want to be in good-standing with the NFIP and provide flood insurance to your residents.

3. Site Plan Review Checklist = Opportunity to better utilize the planning board in floodplain management, regardless of local lawadoption. Can start using this tool now!
