I. PROJECT INFORMATION/LIMITS OF SURVEY:

General Project Location: Lat. 45.165529°N., Long. 88.978616°W. (WGS84)

The project area is located along Bolen Road, the northeastern boundary beginning approximately 400 feet south of WI Rt. 64, in the Town of Polar, Langlade County, Wisconsin. The project area is comprised of four separate tax parcels (or portions thereof), 22-0236, 022-0238.006, 022-0233.002 (part of), and 022-0233.004 (part of).

The National Park Service (NPS) is in the process of acquiring a parcel of land containing approximately 72.67 acres from the Ice Age Trail Alliance for incorporation in the Ice Age

National Scenic Trail (IATR). This parcel adjoins non-federal lands on all sides, except for a portion of the south and west lines of the property, which run along the edge of Mueller Lake.

The parcel of land is the same lands described in a Plat of Survey drawn by REI Civil &

Environmental Engineering Surveying, dated February 3, 2023 as Map No. 20554 and recorded in the Langlade County Surveyors Office. The most recent title commitments, source title documents, and prior surveys are attached for reference.

This project involves locating field evidence required to establish or re-establish the boundary of

Tract 101-08 after conveyance of the subject lands from Ice Age Trail Alliance to the USA. A land survey plat will be prepared and filed in the records of Langlade County, Wisconsin that includes returns from the boundary survey. The contracted firm will also mark and post the new exterior boundary of the subject tract according to the specifications stated herein.

II. PROJECT DETAILS:

A. PERFORMANCE PERIOD AND SCHEDULE:

The selected firm can begin work after the contract award is signed by both the federal contracting officer and company representative. For purposes of this scope of work, the “Start

Work Date” shall be the first business day following receipt of a notice to proceed from the

NPS, which will be provided to the contract firm no sooner than the first business day following recordation of the deed to the USA for the subject property. All work will be completed and delivered within 10 months of the Start Work Date.

A pre-project conference call between NPS and contract staff will take place within two weeks of the award date of this contract.

Progress reports will be provided to the NPS POC on a weekly basis via email or by other electronic means as established by mutual agreement of both parties.

B. PROJECT STAFF:

Project staff must include an individual who is a Registered Professional Land Surveyor in

Wisconsin, fully qualified to perform land surveys, 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.

C. 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 within 15 days of the Start Work Date and 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 NPS POC listed in

Section III to determine appropriate level of notification.

c. Contact the local utility line location services (811) 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 (Complete within 30 days of the Start Work Date)

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 (Complete within 60 days of the Start Work

Date)

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 existing federal 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).

e. Any clearing of vegetation along traverse lines will be kept to a minimum to allow for necessary lines of sight. Only underbrush and trees with a diameter of less than 3 inches will be cut. The remaining stump of any cut tree will project no more than one foot above the ground.

4. Existing Survey Monuments

a. 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 and will monumented as required below in section II.C.5.a.

b. 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 purported (i.e. they are determined to be off line), the letters

“RM” will be added to the monument cap along with an arrow pointing towards the actual boundary line 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.

c. Any recovered monuments purporting to mark boundary corner locations which are found to be in good condition and are accepted as originally intended will be noted on the plat as “found” and not be disturbed.

These monuments will be perpetuated by at least three accessories. One accessory shall be a standard aluminum monument, set at a reasonable distance from the true point and installed to the same criteria listed below in part II.C.5.a., (a 2 3/8 inch diameter, 30-inch-long aluminum or stainless steel post, with a 3 1/4 inch diameter cap bearing the NPS custom cap), oriented north, with cap stamped “RM”, an arrow pointing towards the actual corner location, the RLS No., and YEAR. If there is enough space on the cap, the distance to the actual corner location will be included near the arrow.

These accessories can also consist of bearing trees or bearing rocks and will be identified on the Monument Reference Sheet with a full description including tree species and diameter-at-breast height (DBH), size and position of marks on boulders or bedrock, along with the exact direction and horizontal distance from the monument. In areas where trees or rocks are not available or impractical to use, ½” rebar, 30-inches long, with a 1” diameter cap stamped “RM”, the RLS

No. and YEAR, will be set at a reasonable distance from the corner monument.

Every effort will be made to keep accessories on federal land. (see Exhibit A

“Monument Placement Attachment” for more details and specifics)

5. New Survey Monuments

a. Exterior Corridor boundary monuments established, or missing monuments re-established on any angle points, lot or parcel corners coincident with the

Exterior Corridor boundary line1 of the IATR or significant federal property boundaries identified in this Scope will be, at minimum, a 2 3/8 inch diameter, 30-inch-long aluminum or stainless steel post, with a 3 1/4 inch diameter cap bearing the NPS custom cap, oriented north, stamped with “Tract Number –

State Abbreviation – Monument Number”, the RLS No. and YEAR. (see

Exhibit A “Monument Placement Attachment” for more details and specifics)

Before the monuments and other materials and supplies are procured, a

Monumentation and Marking Plan will be submitted to the COR for approval, within 90 days of the Start Work Date. The Monumentation and Marking Plan shall include an inventory of the quantity, types, supplier, and product code for all monuments, caps, paint, signs, posts, and related materials and supplies required to accomplish this Scope. The plan shall also include a map depicting the locations and numbering schema of the monumentation needs. This ensures that unique numbers are assigned to each monument and avoid number duplication. The contractor will procure all monumentation and marking materials and supplies upon the approval of the Monumentation and

Marking Plan by the COR. Please consult with project POC if site conditions warrant the use of unique survey monumentation or supplies. (1 see

Definitions in Section V)

Each monument set shall be referenced by at least 3 accessories (permanent nearby objects), preferably at locations which create a near 90-degree angle with the corner monument. Wooded areas will utilize trees larger than 4 inches-diameter-at-breast height (DBH) as accessories and will include driving a nail and washer near the center base of the tree to be measured perpendicular to the corner monument and painted for easy identification.

Painting shall consist of one blaze approximately one foot off the ground, with the nail and washer placed in the center, and two blazes at approximately breast height. These accessories can consist of bearing trees or bearing rocks and will be identified on the Monument Reference Sheet with a full description including tree species and diameter-at-breast height (DBH), size and position of marks on boulders or bedrock, along with the exact direction and horizontal distance from the monument. In areas where trees or rocks are not available or impractical to use, ½” rebar, 30-inchs long, with a 1” diameter cap stamped “RM”, the RLS No., and YEAR, will be set at a reasonable distance from the corner monument. Every effort will be made to keep references on federal land. (see Exhibit A “Monument Placement

Attachment” for more details and specifics)

b. Private property monuments established on lands interior to federal lands (a.k.a.

private inholding parcels surrounded in their entirety by federal lands), if any, 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. Additional cap markings may be requested by NPS on a case-by-case basis. Any boundary monuments re-established on controlling corners adjoining the project area or outside the federal land boundaries 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 set to the same criteria listed above in part II.C.5.a. (i.e. an aluminum 2 3/8” diameter pipe, 30 inches long, with the standard 3 ¼” diameter aluminum cap, with custom NPS logo) established as close as practicable near the actual corner and on-line going into or out of corner position, with the word “OFFSET” stamped on the cap and 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. These monuments will not be referenced by accessories.

(see Exhibit A “Monument Placement Attachment” for more details and specifics)

e. Intermediary points will be established on lines of excessive length and installed to the same criteria listed above in part II.C.5.a. (i.e. a 2 3/8 inch diameter, 30-inch-long aluminum or stainless steel post, with a 3 1/4 inch diameter cap bearing the NPS custom cap) and stamped with the number of the preceding Corner Monument then a letter suffix (e.g. 266-NY-36A, 36B, and so on down the line). These monuments will be placed at a maximum distance of 500 feet from the preceding monument. These monuments are intended to be online, but not control the line. They will be noted on the Plat of Survey and Monument Reference Sheet, with a note indicating their purpose. The statement may say “Intended to be on-line but does not control the line.” (see Exhibit A “Monument Placement Attachment” for more details and specifics)

6. Other Survey Tasks

a. All Exterior Corridor Boundary lines will be marked with blazing, paint, and signage. (see Exhibit B “Line Marking and Posting Attachment” for more details and specifics)

D. 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 in the Public Land Survey System (PLSS) states, when applicable. 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.

E. 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 or combination thereof. Both will be described and referenced on the final plat in Wisconsin State Plane Grid Coordinates, Central, NAD

83(2011), U.S. Survey Feet. 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. 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.

F. DELIVERABLES:

All deliverables and products created under this project including such items as 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. Once approved by the local jurisdiction (when applicable) and NPS, 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.

V. OTHER CONTRACT DETAILS:

DEFINITIONS:

Federal boundary line as used herein references the boundary of the park unit as established through federal land acquisition. For this project, the federal boundary lines (a.k.a. “Exterior

Corridor” boundary) are those boundary lines where the property on one side of the boundary is owned or will be owned (after the acquisition is completed) by the federal government and managed by the National Park Service, and the adjoining property is either non-federal (e.g., private, local municipality, state agency) or federal land managed by another federal agency

(e.g., US Forest Service, US Bureau of Land Management). Unlike traditional park units, the

National Trails System, by legislative design, does not include static legislated park boundaries.

Therefore, the term “park boundary” as used herein is synonymous with “federal boundary” or

“Exterior Corridor” boundary. Consult with NPS staff for clarification if needed.

CONFIDENTIALITY:

The information developed under this contract is the property of the U.S. Government and will remain in strict confidence unless otherwise indicated.

INSPECTION AND ACCEPTANCE:

NPS park staff and the contractor’s representative will coordinate options for a final walk-through of the project area prior to the end date of the contract. The purpose of this walk-through is to provide park staff with a final visual inspection of the location and physical characteristics of all boundary markers found or placed during this survey.

mailto:Alex_Faught@nps.gov

All deliverables will be provided to the technical point of contact in a draft format for review and approval prior to the end of the contract date as noted above under Performance Period and Schedule.

ARCHAEOLOGICAL AND CULTURAL FINDINGS:

NPS is responsible for all required NEPA/106 investigations and compliance prior to survey work. If the contractor or subcontractor discovers archaeological or cultural artifacts during field work, immediately stop work and contact the technical or park contact listed in Section

III.

INSURANCE:

The contractor or subcontractor agrees to maintain the following insurance for the term of this contract. Certificates of insurance will be provided at the request of the government.

1. Worker’s Compensation Insurance, in the form and amounts required by statute or other applicable law.

2. General Liability Insurance with limits of $1,000,000 per occurrence.

3. Professional Liability Insurance with a limit of $1,000,000.

4. Commercial Automobile Liability Insurance with a combined single limit of $500,000.

Exhibit A

Monument Placement Attachment

A. Monument Placement: Monuments set during the course of this survey will be, at minimum, a 2 3/8 inch diameter, 30-inch-long aluminum or stainless steel post, with a 3 1/4 inch diameter cap bearing the NPS custom cap (see Inset A).

Monuments established in rock or concrete surfaces will be, at minimum, a 2 3/8 inch diameter brass or bronze cap, with a 2 7/8-inch stem, bearing the NPS custom cap (see Inset A), drilled and set in place with concrete or epoxy, and be oriented and marked as stated below (see ii below).

Found monuments along the exterior corridor boundary of a permanent nature such as trees (See iv.3 below), large corner stones, concrete monuments, and railroad rails, shall not be replaced, but will be referenced as above.

i. Monument References: Each monument will be referenced to a minimum of three (3) permanent nearby objects such as nails and flashers in trees, chiseled crosses in boulders or bedrock, and so forth. The references will be painted for easy identification. Reference points on trees shall consist of one BLAZE approximately one foot off the ground, with the nail and flasher placed in the center, and two BLAZES at approximately breast height. References will point toward the monument. A BLAZE is made by cutting off a vertical strip of bark down to the cambium. The strip should be about 6" long, 2-4" wide and the top and bottom ends smoothed out so the blaze forms an ellipse. A square cut with the ax will not be allowed as this leads to a pocket where water is trapped and rot begins. In areas where trees or rocks are not available or impractical to use, ½” rebar, 30-inchs long, with a 1” diameter cap stamped “RM” will be set at a reasonable distance from the corner monument. Paint shall be NCP Coatings BarkMark

Boundary Marking Paint, Color TBD and shall cover the entire blazed area to prevent rot and infection. IN RESIDENTIAL AREAS, EVERY

EFFORT SHOULD BE MADE TO KEEP REFERENCES ON U.S.

PROPERTY. REFERENCES ON ADJOINING PROPERTIES MAY

ONLY BE PLACED WITH EXPLICIT WRITTEN APPROVAL BY

ADJOINING LANDOWNERS. WRITTEN APPROVAL MUST BE

INCLUDED IN THE DELIVERABLES.

ii. Monument Stamping: All monuments with NPS custom cap will be oriented NORTH and, at minimum, will bear the registration number of the professional land surveyor in responsible charge, the year set, and corner numbering. All markings will be carefully arranged, neat, distinct, and durable. The contractor will stamp each monument with a die of ¼” in type size. A complete set of dies with all letters, numbers, and symbols is required. The monument stamping convention is: Segment Number – State Abbreviation –

Monument Number, i.e., 101-08-WI-36 as shown on Inset B.

Corner Monuments are numbered with a whole number such as “36”.

Intermediate on-line Monuments are numbered with the number of the preceding Corner Monument then a letter suffix: 101-08-WI-36A, 36B, and so on down the line. As new tracts are acquired on either side of the original corridor, letter suffixes are added to the Segment Number to indicate the addition, for example 101-08A-WI-36. Before the monuments are stamped, an electronic copy of the AutoCAD working drawing will be sent to the

NPS COR, for review and assignment of monument numbers. This is to ensure that unique numbers are assigned to each monument and avoid number duplication.

iii. Offsets: When offsets are employed, they should be set on the boundary as close to the actual corner locations as possible and on-line going into or out of corner position. These offset monuments are to be stamped with the word “Offset”, and then followed by the distance of the offset (See

Inset A). Offset monuments will be located after placement and their distance identified on the Monument Reference Sheet.

iv. Roads & Trees:

1. Where boundary lines follow a road centerline, only lines entering and leaving the right-of-way should be monumented, by offset, at the intersection of the boundary line and the right-of-way.

2. Where boundary lines cross roads, monuments should be placed at the intersection of the boundary line and the right-of-way on either side of the road.

3. Where the corner monument is a tree, the tree shall be marked with three blazes where the boundary line enters the tree and three blazes where the boundary line leaves the tree (six blazes total).

Blazes shall be painted as described above. One A1NB30 or

RT35D shall be set on the boundary line either entering or leaving the tree as close to the tree as possible and labeled as an offset as described above.

v. Intermediate On-line Monuments: Additional monuments will be set on lines of excessive length. The placement of these monuments will be at a maximum of 500 feet from the preceding monument and set on-line with the same requirements as the corner monuments. On-line monuments can be shifted along the line as needed (though not to exceed 500 feet between monuments) to benefit the placement of any type of monument.

These monuments are intended to be online, but not control the line and will not be referenced by accessories. They will be noted on the Plat of

Survey and Monument Reference Sheet, with a note indicating their purpose. The statement may say “Intended to be on-line but does not control the line.”

Line Marking and Posting Attachment

1. Boundary Signs: U.S. boundary signs (see example diagrams below) shall be nailed to trees on or near the boundary line at a maximum interval of three hundred (300) feet, less if necessary for visibility between signs. Adjacent signs should be visible from each other. Metal signs are preferred, but plastic may also be used. The sign will face towards the adjoining landowner and will be placed conspicuously, specifically at the intersection of all roads, streams, trails, pipelines, fence lines, etc. Additionally, signs will be placed by all corner and intermediary monuments. Signs are to be fastened to trees approximately five feet above ground level with 12d aluminum or galvanized box nails (2 nails per sign). The head of the nail will be left approximately ½” from the tree to allow for growth. In open areas where no trees or other objects are near the boundary line to which signs can be affixed, intervisible metal fence posts with signs attached with durable wire or plastic ties shall be installed by the contractor.

These fenceposts shall be approximately six (6) feet in length and will be set 18 inches in depth and reinforced as required. Generally speaking, signs should be placed so that it is perfectly clear to anyone crossing the boundary at any point that they are entering U.S. government property.

2. Blazing and Painting: In addition to the Boundary Signs, the exterior corridor boundary lines will be well marked by blazing and painting. All trees located on the boundary line will be blazed as line trees by a painted blaze on each side facing the direction of the line. In order to make a line that can be easily followed, trees on each side of the line and within one (1) foot of the line will be blazed as a line tree with an additional painted blaze on the side facing the line.

Other trees, within three (3) feet of the line will be marked with only one (1) painted blaze on the side facing the line (See A04 SOW Line Posting Attachment Page 3 and 4). Blazes will be located approximately five feet above ground level. Paint shall be NCP Coatings BarkMark

Boundary Marking Paint, Color TBD and shall cover the entire blazed or hacked area to prevent rot and infection. IN RESIDENTIAL AREAS, BLAZING AND PAINTING ON

ADJOINING PROPERTY MUST ONLY BE DONE WITH EXPLICIT WRITTEN

APPROVAL BY THE ADJOINING OWNER. WRITTEN APPROVAL MUST BE

3. Clearing:

a. Traverse Lines: Clearing along traverse lines will be kept to an absolute minimum to allow the necessary lines of sight. Only underbrush and trees with a diameter of less than 3 inches will be cut. The remaining stump of any cut tree will project no more than one (1) foot above the ground.
