I. PROJECT INFORMATION/LIMITS OF SURVEY:

General Project Location: Lat. 13° 27’ 41” N., Long. 144° 41’ 40” E. (WGS84)

This project area is generally located in Piti, Guam, in the Piti Guns Unit of WAPA. East of Guam Highway-1, North of Guam Highway 6, and West of Nimitz Hill. See the attached Plan of Survey diagram.

The National Park Service (NPS) owns two contiguous tracts of land, identified as Tracts 104-01 and 104-02 on the Plan of Survey Diagram.

SOW, Boundary Survey Services Page 2 of 9

Tract 104-01 is the WAPA legislative boundary, this tract is made up of all of tax Lot 260 and a portion of another tax parcel, Lot 259. Tract 104-02 is the remaining portion of Lot 259 that is not located within the WAPA legislative boundary but is National Park Service land. This project is to survey tract 104-01, the legislative boundary and determine what portion of Lot 259 is in the WAPA boundary and will be retained by the National Park Service. The remaining portion of Lot 259 will be given back to Guam.

This project will involve specific survey research to determine the origin of the legislative boundary between tracts 104-01 and 104-02. There are reports from former park personnel of Navy survey moments in the vicinity of some of the turning points on the line between the two tracts but there is no record of survey available to NPS currently. Research must be conducted, and these unrecorded monuments need to be properly evaluated for age, use, and position. The diagram provided is a draft to show what lines must be delineated. Deed research and survey records not available to NPS must be obtained and evaluated to ensure the boundary is properly identified and any junior/senior rights that would affect the boundary location are considered.

As well as research, the project will include, evaluating field evidence for boundary control, setting monuments, recovering monuments, marking boundary line, producing land descriptions and collecting any evidence of trespass or encroachments originating from the adjoining private parcels across the NPS boundary line.

A land survey plat will be prepared and recorded in the records of Guam Department of Land Management per Guam requirements and land descriptions will be prepared for use in the transfer of property.

II. PROJECT DETAILS:

A pre-project conference call between NPS and licensed contract staff will take place within two weeks of the award date of this contract, the licensed surveyor must attend this meeting.

Progress reports will be provided on a monthly schedule.

Draft deliverables will be submitted electronically to the technical POC listed in Section III for review no later than two months before the end date of the contract. The reviewer will provide approval or request for changes within 14 days of receipt of the draft documents. The contractor will deliver all final products except the recorded plat to no later than October 30, 2026. A copy of the recorded plat will be delivered no later than December 30, 2026.

PROJECT STAFF:

Project staff must include an individual who is a Registered Professional Land Surveyor in Guam, in good standing in the territory of Guam, fully qualified to perform land surveys, SOW, Boundary Survey Services Page 3 of 9 prepare legal descriptions, and comply with all applicable federal, state and local laws. This person will be the responsible charge of the land survey work and all land survey decisions.

STANDARD SURVEY TASKS:

The contractor will provide labor, equipment and supplies to complete a boundary survey as identified herein unless otherwise noted. Specific tasks noted below will be completed as part of this project:

1. Landowner Contacts (complete prior to field work)

a. Contact the NPS park contact to provide times and dates of entry and coordinate any logistics regarding physical access to the project area (reference Section III for contact information).

b. Contact all adjoining private property owner(s), if applicable, to provide times and dates of entry and obtain permission if needed or required by local jurisdictions (reference Section III for contact information). For larger projects, a general window of anticipated field work can be provided in lieu of specific times and dates. Please coordinate with the Technical POC listed in Section III to determine appropriate level of notification.

c. Contact the Office of the Mayor, Municipality of Piti, to notify the current Mayor of Piti, Guam.

d. Contact the local utility line location services if there are any indications of utility infrastructure in the project area. Contractor is responsible for any damaged utility lines from survey activities. Please request that markings on hard surfaces be minimized to the greatest extent possible.

2. Records Research Contractor is responsible for conducting the necessary research required to complete the tasks listed herein. To the extent available, NPS will provide land title, survey records, maps or other documents in the possession of NPS related to the project area.

3. Investigate Boundary Line Evidence

a. The character and location of evidence of possession or occupation along the perimeter of the surveyed property, both by the occupants of the surveyed property and by adjoiners, observed in the process of conducting the fieldwork.

b. Without expressing a legal opinion as to the ownership or nature of the potential encroachment, the evidence, location and extent of any conflicting boundary evidence related to record title documents.

c. The location, size, character, and type of any monuments found during the fieldwork, including legislated park boundary monuments and private property boundary monuments.

d. The location, description, and character of any lines or natural features that appear to delineate or control the boundaries of the surveyed property (i.e. fences, walls, rivers).

4. Existing Survey Monuments

a. Any existing local monuments recovered and accepted as demarking property boundary extents will be left in place or remonumented to meet the local standards or requirements.

SOW, Boundary Survey Services Page 4 of 9

b. Any recovered monuments purporting to mark boundary corner locations which are found to be deficient or are not accepted as originally intended will be noted on the plat, including a brief summary of the evidence used to make this determination.

These corners will be considered lost, requiring a new survey monument be established at the most defensible location of the boundary corner.

c. In the event any existing survey monument(s) established by prior National Park Service surveys (either contract or in-house) are not accepted as boundary monuments as noted above in 4.b, the letters “RM” will be added to the monument cap along with an arrow pointing towards the actual boundary line or angle point and the year of the current survey. If there is enough space on the cap, the distance to the actual corner location will be included near the arrow.

5. New Survey Monuments

a. Legislated park boundary monuments established or missing monuments re-established on any angle points, lot or parcel corners coincident with the legislated boundary line1 of the National Historical Park or significant federal property boundaries identified in this Scope will be at a minimum a ⅝ inch diameter iron rod or rebar, 30 inches long with 2 inch diameter metal cap in a poured concrete base.

The cap will be set flush in the concrete. The concrete base will be 4-6 inches in diameter and will extend 12-18 inches below the surface surrounding the rebar and base of cap, and cap stamped, “NPS/PARK/ Project Point No./YEAR/RPLS No.”

Corners located in bedrock will be a minimum of a 2½ inch diameter brass or bronze cap with 3 inch stem (preferred), drilled and set in place with concrete or epoxy. Please consult with NPS staff if site conditions warrant the use of unique survey monumentation. (1 see Definitions in Section V)

b. Private property monuments established on lands interior to the legislated park boundary (a.k.a. private inholding parcels), will be at a minimum a ⅝ inch diameter iron rod or rebar, 30 inches long with 1 inch diameter metal cap stamped with the surveyor’s or firm’s license number and year of the project. Any boundary monuments re-established on controlling corners adjoining the project area or outside the legislated boundary will comply with current federal, state or local requirements and will be noted on the plat.

c. Temporary project control point(s)/traverse station(s) established will comply with current federal, state, or local requirements. All project control monuments will be clearly marked to differentiate these from property boundary monuments. Where practicable or in areas where project control may be confused with boundary location, control monuments will be removed after field work is completed and draft deliverables have been approved. All project control monuments which remain in place will be noted on the final plat.

d. Corner locations that are inaccessible will have a reference monument installed to the same criteria listed above, established as close as practicable near the actual corner.

e. Any reference monuments established will clearly note “RM” with an arrow pointing towards the actual corner location. If there is enough space on the cap, the distance to the actual corner location will be included near the arrow.

6. Other Survey Tasks

SOW, Boundary Survey Services Page 5 of 9

a. All areas and features of encroachment onto USA lands (examples include cleared land, mowed areas, gardens, fences, buildings, roads, trails, riprap, etc.) Note the area of the encroachment(s) as surveyed in acres to the nearest hundredth (0.01). Parcels less than 0.01 acres will be reported in square feet. The length of linear encroachment features will be noted to the nearest tenth of a foot (0.1). Photos (with information on what the photo depicts) of all encroachments will be taken and provided as a deliverable.

b. Boundary line marking will be a combination of metal t-posts (more permeant marking) along certain lines and temporary line marking on other lines, consisting of a wood stake or hub and a 60d nail alongside the stake. Line markers will be placed at 200-300 ft. intervals (or line of sight between each) during the course of the survey project.

There will be a discussion about boundary line marking in the pre-project meeting to get the surveyor’s input on materials and permanent verse temporary line marking materials for certain lines. Given conditions it may be more ideal for wooded areas to have more permanent boundary line markers while areas near residential property may benefit from temporary stakes along the line.

SURVEY STANDARDS OF CARE:

1. Other Requirements and Standards of Practice - Many states and some local jurisdictions have adopted statutes, administrative rules, and/or ordinances that set out standards regulating the practice of surveying within their jurisdictions. In addition to the standards set forth herein, surveyors must also conduct their surveys in accordance with applicable jurisdictional survey requirements and standards of practice. Where conflicts between the standards set forth herein and any such jurisdictional requirements and standards of practice occur, the more stringent must apply.

2. Prior Federal Surveys - The procedures used to recover or reestablish any previous federal survey monuments or lines that control the location of any project boundary will comply with the federal “Manual of Survey Instructions” in affect at the time of the survey. New monuments or controlling corners not previously established will comply with the most current “Manual” version prepared by the Bureau of Land Management, unless otherwise indicated by this document. Federal surveys include all approved Public Land Surveys or official federal boundary surveys completed for the National Park Service or other agency.

3. Boundary Resolution - The boundary lines and corners of any property or interest in real property being surveyed as part of this contract must be laid out in an original survey or by retracement of existing boundary lines in accordance with appropriate boundary law principles and location doctrines governed by the set of facts and evidence found in the course of performing the research and fieldwork.

4. Measurement Standards - The acceptable relative positional accuracy of the survey is the same as identified in the current version of Section C, NSPS Classifications and Accuracy Standards for Property Surveys.

SOW, Boundary Survey Services Page 6 of 9

SURVEY & MAPPING CONTROL:

All reported horizontal distances will be based on ground measurements in either U.S. or International Feet at the discretion of the surveyor or as required by law. The basis of bearings for the project is at the discretion of the surveyor. Both the units and basis of bearings will be noted on the plat.

At least two survey monuments (existing or new) within the project extents will serve as mapping control points. These can be existing property corner monuments, project control points, NGS monuments, Guam Geodetic Network monuments or combination thereof. Both will be described and referenced on the final plat in the Guam Geodetic Network (1993 GGN) Datum grid coordinates, U.S. Survey Feet (or other datum and units that may be required by Guam law to file a plat). The grid coordinate pairs for each point and combined scale factor from ground to grid will also be noted. If either control point is not a boundary monument, sufficient information will be included to tie it to a boundary monument. These points should be located on opposite sides of the project area if possible.

At least one of the control points will be occupied by a dual-frequency GPS unit for a minimum of four hours. A current Online Positional User Service (OPUS) solution data sheet for this monument will be provided as a deliverable (or similar if OPUS is not available for Guam – an adjustment based on continuously operating reference stations for the local area). If site conditions prevent the use of GPS equipment, sufficient information will be included on the plat as to the procedure and control utilized to determine coordinate information.

DELIVERABLES:

All deliverables and products created under this project including such items certified plats of survey, field notes and research documents used to produce this survey and descriptions are considered property of the National Park Service, U.S. Department of the Interior.

At a minimum, one land survey plat will be prepared on an 18”x24” (Architectural C) or 24”x36” (Architectural D) map sheet. The size will be based on any state or local requirements or the surveyor’s professional opinion as to the appropriate degree of precision to convey the required information in an easy to understand manner. A copy of this plat will be deposited or recorded in the designated public land records office in which the project is located. In jurisdictions where no recording procedures exist for plat recordation, two signed and sealed original plats will be provided to NPS.

Detailed information or decisions related to corner evidence, acceptance or rejection of conflicting monuments, land records research, or any other unique situations that are not required to be documented on the face of the plat but are deemed important to the survey results will be provided as a separate Land Surveyors Report to accompany the plat. The report will be signed, sealed and dated by the surveyor in responsible charge of the project.
