Natrona, WY: Flood maps and elevation records serve different purposes
Natrona County provides Flood Insurance Rate Maps and Elevation Certificate resources through its floodplain information page. These are distinct records used when evaluating development and existing elevations.
Remote plan-based takeoff support; no local office, completed local project or site investigation is represented by this page. Cost, delivery schedule and deliverables depend on the agreed project scope.
What this changes in the bid review
Estimating interpretation: An existing elevation record does not define a new grading design. Keep existing surveyed levels, flood-map information and proposed surfaces in separate inputs so they are not accidentally combined into a false cut-and-fill model.
Check the project documents
Clarification to request: Do the existing survey, elevation record and proposed grading model use a confirmed common datum?
