Minor Overwater Development Projects
Floodplain Habitat Assessment Short Form
Project Information
Applicant name:
Project Location (Address / Parcel Number):
Short Project Description:
This habitat assessment short form is for all minor overwater development projects on
existing docks within the Special Flood Hazard Area (SFHA; also known as the 100-year
floodplain) of Lake Sammamish. Minor overwater development projects on existing docks
include the following types (check the box that applies to your project):
Replacing existing wooden decking with WDFW-approved grated decking providing a
minimum of 40 percent light transmission through the new decking material (as documented by
decking manufacturer specification).
Wrapping existing piles with high density polyethylene (HDPE) material or other non-
galvanized material approved by the City and WDFW, provided such work does not entail pile
replacement.
Repairing caps and stringers (framing and structural components that are supported by piles,
and that provide the dock structure underlying the decking); and
Installing new boatlifts, provided such work does not entail placement of new piles (or pile
replacement), and does not include grading, clearing of native riparian vegetation to provide new
electrical supply, filling, or impervious surfaces.
Note: WDFW habitat biologists can provide verification that proposed activity meets WDFW
standards.
If your overwater development project does not meet one of these types, then a more
detailed habitat assessment will be required.
Each section of this habitat assessment short form must be completed, including verification
and attachment of additional project information and plans.
Instructions
As the applicant, please check boxes in Sections 1-3 and provide short responses where
necessary to verify that your project is consistent with required habitat assessment
components, and includes the specified best management practices (BMPs) in Section 3 of
this form. City Planning/Permitting staff will verify that the components in Sections 1-3 have
been documented satisfactorily and will complete the final page of this form. If a component
or specific BMP does not apply to the project, a brief explanation must be provided.

1. Project Submittal Verification Additional Required Information
Waterbody or waterbodies within and adjacent to where the project will occur are described
(water typing included)
Methods of work are described (within permit applications, and/or supplemental materials as
necessary)
Project area map is provided (may be the same as the project area map submitted with your
shoreline permit / building permit)
Site plans are provided (may be the same as the plans provided with your shoreline permit /
building permit, along with this Short Form Habitat Assessment) that include:
Footprint and pile locations for existing dock structure; and
Identification of dock elements that will be replaced or repaired; and/or
Locations of any new boatlifts.
2. Confirm that the Proposed ‘Minor’ Overwater Development Activity does not include
any of the following activities:
No clearing of shoreline vegetation will be required for the project
Staff Verified:
No new impervious surfaces will occur at the dock landing or elsewhere
Staff Verified:
No in-water work waterward of OHWM will be required for the project.
Staff Verified:
No new or expanded bulkhead or beach nourishment activities are
proposed along the shoreline.
Staff Verified:
3. Confirm that Minimum Required BMPS address Potential Direct and/or Indirect Habitat
Impacts below:
Potential Impact
Minimum Required BMPs
Staff Verified:
Overwater
Shading
No net increase in overwater coverage; and
Grated surfaces used or openings provided in the deck
surface to pass light.
Water Quality
Work to be performed in dry weather and/or during dry
season (May 15- September 30); and
Low impact development techniques used;
Exposed soil / excavated earth stabilization measures
included in proposal; and
Any other appropriate construction BMPs provided (rain
garden for driveway or downspouts, native/drought tolerant
plant landscaping, pervious pavement, or other approved
strategy).
Additional project applicant comments/information (optional):
Signature By signing below, City of Sammamish staff have determined an effects
determination of No Effect (NE) or May Affect, Not Likely to Adversely Affect (NLAA) for the
proposed project. As documented in this Floodplain Habitat Assessment Short Form, the
effects determination has been made consistent with FEMA Region X guidance for Puget
Sound implementation of the NFIP consistent with the Endangered Species Act.
Applicant signature indicates that the project proponent will limit floodplain development
activities to those described in this Short Form, and commits to implementing all BMPs as
detailed above and as conditioned by the City on this form.

Check each box once verified
City staff review notes
Project is limited to ‘minor’ overwater development activity, and
does not include any of the elements listed in Section 2.
All minimum required BMPs have been met
All potential direct and/or indirect habitat impacts have been
addressed
The project design inherently avoids adverse effects. Project design
elements that consider and improve floodplain functions which support
ESA-listed species should be directly incorporated into the project.
The project results in in no effect or not likely to adversely affect
ESA-listed species.
Additional Information / Supplemental Staff Conditions
Other project information necessary to support the effects determination:
Yes (provide notes / references to other submittal materials below) Not applicable
Staff has determined that implementation of the following supplemental conditions necessary to
support the effects determination:
Yes (detail supplemental conditions below) No supplemental conditions required
