Continental Mapping performed a boundary recovery survey of a 3 mile levee in Cleveland, Oklahoma. The levee is to protect Cleveland, OK residents from Lake Keystone’s flood waters. The purpose of the survey is to establish specif-ic boundary lines of property owned by the government as well as identifying adjoining land owners along the levee and all encroachments and features along the levee boundary line. Work included resetting all destroyed or missing corner monuments and setting any new boundary corners established since the original acquisition (1962) by the Pawnee County Surveyor.

The original monuments contained no metal, making locating buried monu-ments difficult for the survey crew. In all, 78 of the 116 original monuments were found, 21 lost monuments were reset, 4 witness corners were set due to obstructions, 2 broken monuments were reset, 5 missing corners were not reset because they landed in the middle of paved roadways, and 6 because they were not corners.

Continental Mapping conducted legal description research, monument placement and mapping of the landslide boundary of the levee. Conti-nental Mapping also prepared a survey plan describing boundary lines,

monuments found, and all encroachments. This survey was performed in Oklahoma North State Plane Coordinate systems. Coordinates were recorded for each corner monument and displayed on the plat of survey. Several encroachments were located along the boundary and were depict-ed on the plat of survey.
