Planning Department Services & Documents

The City of Sultan is pleased to announce we will provide floodplain information upon request.

Maps

We maintain a complete library of City of Sultan Flood Insurance Rate Maps (FIRMs). These maps are available at City Hall, and in the Sultan Sno-Isle Library.

At City Hall we also have topography mapping showing 75% of the City. We have created flood maps that have the following attributes:

  • Base Flood Elevations Mapping in Some Unnumbered a Zones: Shows interpolated flood elevations using best available information
  • LOMA Map: Shows location of all Letters Of Map Amendment, includes case Number
  • Repetitive Flood Loss Map: Showing location of flood losses that equal or exceed $1,000
  • Water Depth: Shows the base flood Elevation in relation to ground Elevation

This information is an incalculable asset helping you meet State and Federal law requirements.

Publications

We also maintain a library of Department of Homeland Security Federal Emergency Management Agency publications regarding all aspects of flood damage prevention.

Other Records

The City of Sultan also keeps on record:

  • Conditional Letters of Map Amendment
  • Elevation Certificates
  • Elevation Determinations
  • Letters of Map Amendment (LOMA)
  • Letters of Map Revision (LOMR and LOMR-F)
  • Reinstatement Letters

Site Review

We also provide on-site project review; we will meet with and/or your clients at the project site upon request.

Using the adopted Flood Insurance Rate Maps, we will determine the Base Flood Elevation and incorporate this information in section B9 of an elevation certificate to be completed by a Washington State Registered Professional Land Surveyor.

We will review all certificates and documents for completeness and accuracy.

NFIP education corner: LOMR versus LOMR-F

What's the difference between LOMR and LOMR-F?

They have similar names but different map-change processes. Both a LOMR (Letter of Map Revision) and LOMR-F (Letter of Map Revision based on Fill) are types of Letters of Map Change, or LOMC. But the outcomes of the two processes are very different. 

A LOMR is used to revise a Flood Insurance Rate Map (FIRM) and is required when there's a physical change to the floodplain boundaries, floodway, or flood elevations in a community. New and better data, such as more site-specific data, also can be used to update the FIRM using the LOMR process. Sometimes LOMRs are preceded by conditional approvals, or CLOMRs (Conditional Letter of Map Revision), which are required when a new development in the floodway increases the base flood elevation. 

A LOMR-F doesn't revise the FIRM. These are used for structures built on earthen fill in the floodplain and are issued when the lowest adjacent grade to a structure is above the base flood elevation. FEMA issues an official letter changing the flood zone designation for the property, but not the FIRM itself. If the property is reclassified to Zone X, the property owner would no longer be required by FEMA to carry flood insurance (although their lender may still require it, and it may be advisable to maintain flood insurance).
