EXHIBIT 8A

EXHIBIT 8B

PURPOSE: The purpose of this contract was to perform professional land surveying services.

This contract included:

(List each required service, which will normally correspond to the contract pay items)

HISTORY OF PRIVATE SURVEYS: Briefly state the name and date of any private surveys, that are not indicated on the cadastral plat, that affect this survey. The report should detail why the private survey was or was not used in the conduct of this survey.

PROCEDURE:

CORNER SEARCH CONDUCTED: State the result of corner search efforts. It is not necessary to repeat the detailed information contained in the corner record forms, but the minimum information required is (1) which corners were located by original physical evidence, (2) which corners were located by parole evidence, (3) other surveyor's monuments were accepted, and (4) which corners were considered lost and a brief explanation of the extent of search efforts for the original physical evidence of the monument and accessories.

REMONUMENTATION ACCOMPLISHED: State which original corners were remonumented.

CONTROL SURVEY : Briefly describe the method or combination of methods that were used to

(1) obtain the position of the controlling corners,(2) layout the position of lost corners and any new corners required to be established by the contract, and (3) locate the position of points on the boundary necessary for marking and posting the line. An example follows:

"A 5" total station with specifications of plus or minus 2mm plus 2 PPM was used on the control survey. The instrument was in proper adjustment and a base line user's report for the EDM is attached. The control survey utilized traverse methods that formed closed loops, which were adjusted by least squares method. Boundary lines were located by running true line between corner monuments. Angles were taken one direct and one reverse and these two angles were averaged and used for computations. Backsights were made to nails in the top of 1-meter laths and foresights were to plumb range poles. The estimated sighting error is 0.03 feet average. Distances were measured once to the foresight leg. Reductions to the horizontal were accomplished by means of vertical angles repeated twice in the direct and reverse position to the center of the prism, which was at a constant height of 6 feet. Computed moves were accomplished by turning the angle and shooting the distance direct and reverse.

EXHIBIT 8C

Monumentation: Explain the rationale for accepting or rejecting any other survey monuments found in the vicinity of a computed corner position. Explain what proportioning method was used to reestablish lost corners from adjacent existing corners. List which corners were established and monumented.

LAND OWNER CONTACTS AND CONFLICTS: Cite the result of landowner contact for permission to enter and mark and the private side of the boundary line. Include a brief statement of any apparent conflicts of possession or title discovered.

ENCROACHMENTS: Include a narrative of encroachments discovered and reported to the Contracting Officer Representative.
