The Drawings, Construction and material Specifications, and
Operation and Maintenance Plans for this project have been
reviewed with me and are accepted for this installation. I also
acknowledge that any modifications prior to review by the
NRCS before implimentation may result in NRCS disapproval of
this installation. I hereby acknowledge receipt of a
copy(ies) of this plan.
This is not a boundary survey. Elevations shown are based on an assumed datum.Topographic information was gathered under direction of the engineer for the solepurpose of design and construction of this project. Property lines, easements, andright of way locations displayed are approximate based on information obtainedfrom recorded documents, for reference purposes only. Field data collected 12-2015.
