FEMA Floodplain Site Review
Lewis County Ports deserve exact-parcel floodplain due diligence.
A place-name search does not replace a parcel review. FEMA mapping should be used
to check the exact building pad, access route, utilities, drainage, and proposed
industrial footprint before public dollars, private capital, equipment, inventory,
or jobs are committed.
Winlock Industrial Park
Exit 63 reference area
The FEMA Flood Map Service Center result for the Winlock / Exit 63 / I-5
reference location displays the selected point outside the mapped Special
Flood Hazard Area shown on the map.
Higher-Ground Starting Point
Port of Centralia
Chehalis Basin site review
Port Centralia properties are part of the broader Centralia and Chehalis
River Basin development corridor. Businesses should not rely on a general
city search—each industrial parcel needs current FEMA mapping, site elevation,
drainage, access, and permitting review.
Exact Parcel Review Required
Port of Chehalis
Flood exposure must be checked
Port Chehalis properties should also be evaluated through an exact address
or coordinate search. Floodplain status, local drainage, road access,
insurance requirements, and building-pad elevation should be confirmed
before a business signs, builds, or invests.
Exact Parcel Review Required
Why Winlock stands apart: the FEMA reference map for the Exit 63
area does not display the selected Winlock location inside the mapped Special Flood
Hazard Area. That makes Winlock Industrial Park a stronger place to begin higher-ground
industrial planning. Final decisions must still use the exact parcel, a current FEMA
Dynamic FIRMette, survey information, engineering review, insurance review, and
Lewis County permitting requirements.
