This design complies with ORS 92.044(7), in that no utility infrastructure is designed to be within one (1) foot of a survey monument location shown on a subdivision or partition plat. No design exceptions nor final field location change shall be permitted if that change would cause any utility infrastructure to be placed within the prohibited area.

BASIS OF BEARING:

South 66°27'36" east 819.64 feet between monument number 209 and monument number 221 per Washington County survey records.

ELEVATION DATUM

Elevation of 216.375 feet based on NGVD 29/47, Washington County Benchmark No.924.
