The Boundary and Annexation Survey (BAS)

The Census Bureau conducts the Boundary and Annexation Survey (BAS) annually to collect boundary information about federally recognized American Indian reservations, including off-reservation trust lands and tribal subdivisions. The Census Bureau’s primary purpose for delineating tribal boundaries is to develop the best possible geographic framework for the tabulation and presentation of statistical information. For tribal governments with reservations or off-reservation trust lands, the Census Bureau developed the Tribal BAS to obtain and maintain the most current, legally established boundaries of reservations and off-reservation trust lands.

In support of the government-to-government relationship with federally recognized American Indian tribes, the Census Bureau works directly with tribal officials to maintain a current and comprehensive inventory of correct names, legal descriptions and legal boundaries for federally recognized tribes with reservations and/or off-reservation trust lands. Through the BAS, the Census Bureau updates reservation, off-reservation trust land and tribal subdivision boundaries, as well as their names and features (features such as roads or rivers), and address information at the boundaries. The information collected is used to tabulate data from various programs and surveys, such as the American Community Survey and 2010 Census. Maintaining these boundaries and boundary-to-feature relationships correctly through the BAS makes certain that the appropriate population is assigned to your area.

If there are changes to the boundary of your American Indian Area (AIA), the Census Bureau appreciates your cooperation in completing the BAS forms (offered in either paper or electronic form), marking changes on the maps, and returning the maps and forms to the Census Bureau by April 1.

If a tribal government disagrees with the Census Bureau’s depiction of their boundary and provides supporting documents that pre-date 1990 when our boundaries were last sanctioned by the BIA, we ask for clarification from the U.S. Department of the Interior, Office of the Solicitor regarding the correct current boundary. Often complicated legal land issues require an extended period of time for resolution, and in those cases, the Census Bureau retains the boundary we have in our database until a legal opinion is issued by the Solicitor’s office.

In compliance with the Office of Management and Budget Circular A-16, the BAS supports the Census Bureau’s spatial data steward responsibilities for the Federal Geographic Data Committee and the Geospatial One-Stop by updating the inventory of, and boundaries for, governmental units. In addition, the BAS is the source of up-to-date information on boundaries, codes, and names for the U.S. Geological Survey’s (USGS) National Map and the Geographic Names Information System.

2.0 Updating the BAS Materials

There are six steps involved in updating the BAS materials, including:

Reviewing and updating (if necessary) the geographic information on the form
Reviewing and annotating the map with boundary changes and corrections
Annotating feature changes, additions, or deletions on the map
Annotating the address breaks at the intersection of roads and boundaries
Signing the updated maps and forms
Returning the signed maps and forms

It is important that all questions on the form are answered completely. If there are no changes to report, please return only the “No Change” postcard provided with your materials. Please do not return all of the materials. If there are changes, sign and return only the maps with changes. Return the completed form(s) and updated map(s) within 15 days using the pre-addressed envelope or return label.

2.1 Reviewing and Updating Your Form

Begin with a review of all information printed on your form. If any information needs to be changed, cross out the incorrect data and print the correction beside it as shown in Example 2.1.1 below. Regarding misspelled names, cross out the error and print the correctly spelled name next to the misspelling. Provide an effective date for name, type or status changes. To correct the name of a federally recognized American Indian reservations, off-reservation trust land or tribal subdivision, follow the directions in Question 1 as follows:

Check “No”
Print the correct name and effective date of change
Continue with question 2

Example 2.1.1: Updating the tribal BAS-5 form and Question 1.

2.2 Making Changes and Corrections to Your Maps

This section includes general guidelines and detailed examples illustrating how to update boundary and feature information.

There are a number of general guidelines for changes and corrections to your maps:

Compare the BAS maps to a local source for your entity. Update the map(s) if the boundary shown does not correctly depict the boundary in effect as of January 1 of the survey year.

Refer to examples 2.2.2 through 2.2.5 on pages 6 through 9 for the differences between a boundary change and a boundary correction.

Address Information Update

The BAS maps show the last address stored in our geographic database for each street that crosses the boundary of your reservation. These addresses are shown because it is important that the Census Bureau assigns the correct addresses to each governmental unit. If you have reported an addition or deletion, or have corrected our depiction of your boundary, please provide us with the last address within the current boundary of your reservation.

Since the BAS only targets addresses at the boundary, the Census Bureau has other operations to collect address information. If you have a reliable source for addresses within your reservation, and would be willing to share that information with the Census Bureau, we request that you fill out the Address Source Information Worksheet that is included on the last page of this guide. The Census Bureau staff working on the BAS responses will forward the updated form to the address update staff with the information you provide about the source. The correct assignment of addresses is of primary importance to our censuses and surveys.

Although the BAS collects boundary information, the survey also accepts feature updates. Please refer to examples 2.2.7 through 2.2.15 on pages 13 through 20, and be sure to use the enclosed purple pencil for feature updates.

The Census Bureau is undertaking a nationwide program to improve the positional accuracy of all streets and other features that appear in the Census Bureau’s digital database. It is not necessary to make small positional corrections on the BAS maps; correct only those streets that are significantly mis-located, or new streets that are related to the location of a new boundary.

Do not make changes on the index map. Index maps are provided as a reference to help you quickly locate a map sheet. If you received only an index map for your reservation or trust land and you need to make boundary changes and/or feature updates, please call the phone number indicated on the BAS-5 form or e-mail geo.aiana@census.gov to request a full set of maps or the specific map sheet(s) needed.

The following examples are provided to illustrate how to update your boundary and feature information with the Census Bureau, including:

2.2.1 Explanation of map symbology

This section provides examples of the BAS map symbology. You can review this symbology and BAS map legend online at the following Web site:

http://www.census.gov/geo/www/bas/bashome.html

The following example shows the different boundary symbols used on the BAS maps:

Example 2.2.1.1: Boundary symbology

In Example 2.2.1.2 below, Reservation Cheyenne River Reservation^¹ is the subject area. Trust lands are represented by a brown dot pattern. Incorporated places are represented by color fill and delineated by their respective boundary symbols. Note that all areas outside of the subject area are considered fringe areas. Fringe areas are shaded with a gray dot pattern.

Example 2.2.12: Reservation with incorporated place, tribal subdivision and trust land

2.2.2 Boundary changes versus boundary corrections

The two types of modifications that can be made to a boundary, are: boundary changes and boundary corrections. A boundary change is an alteration to a boundary as a result of a federal court decision, treaty, act of Congress, land taken into trust, etc. Reporting boundary changes is the primary goal of the BAS. A boundary correction is the minor adjustment of a boundary to correct a drafting error in how the Census Bureau depicts an existing boundary and does not require documentation.

2.2.3 Boundary changes

These figures illustrate how to make complete boundary changes, including additions or deletions, to your maps and BAS form. Using the red pencil provided, you will cross out the portion of the boundary that is no longer current with a string of “Xs”. Draw the new boundary line(s) ensuring that you close your boundary and do not leave an incomplete boundary as shown in the figures. Add the authorization number or other identifier of the action authorizing the change, along with the effective date of each addition or deletion that you draw on the map. Document these changes on the BAS form as shown below.

Complete Boundary Incomplete Boundary

Example 2.2.3.1: The figure on the left illustrates how to make a complete boundary change. The figure on the right illustrates a common error with an incomplete boundary change.

Example 2.2.3.2: Updating boundary changes on the tribal BAS form, BAS-5

2.2.4 Boundary with coincident feature change

This figure illustrates how to make an adjustment to a boundary that is coincident with a feature, such as a street. Using the red pencil, cross out the portion of the boundary that is no longer current using a string of “Xs” inside circles. Add the authorization number or other identifier of the action authorizing the change along with the effective date of each addition or deletion. Document these changes on the tribal BAS form as shown in the following figures.

Example 2.2.4.1: Making a change to a boundary coincident with a road feature

Example 2.2.4.2: Updating the tribal BAS form for a change to a boundary coincident with a feature

2.2.5 Boundary corrections

This figure illustrates how to complete a boundary correction on the map and tribal BAS form. Boundary corrections do not require documentation, but we may need to contact you for additional information if the correction requires clarification.

Using the enclosed red pencil provided, you will cross out the incorrect boundaries with a string of “Xs”, add a line showing the correct boundary and print the letters “BC” as shown in the figure below, to identify the change as a boundary correction rather than a change. Document these changes on the tribal BAS form as shown in the following figures.

Example 2.2.5.1: Making a boundary correction

Example 2.2.5.2: Updating the tribal BAS form for a boundary correction

2.2.6 Tribal subdivision program procedures

Tribes may submit the boundaries for one type of administrative area within their reservation(s) and/or off-reservation trust lands (land base) for inclusion into the Census Bureau’s geographic database. The Census Bureau will consider any type of unit of self-government or administration as a “tribal subdivision.” Tribes that delineated tribal subdivisions during earlier BAS cycles have the opportunity to review and correct names, type and status of subdivisions in Question 5 on the BAS-5B form. Additionally, tribes should review the information shown on the maps and note any needed change or correction to their tribal subdivision’s boundaries. Tribal subdivisions should cover all, or most, of the tribe’s land base. If a tribe has more than one type of distinct administrative area that could qualify as a tribal subdivision (e.g., tribal election districts, tribal water districts, or health service areas with different boundaries), the tribe may submit only one type of subdivision. Tribal subdivisions can be considered either active (A) or inactive (I). Active subdivisions are defined as having a functioning government with elected officials that provides programs and services. Inactive subdivisions have no functioning government or elected officials and receive services solely from the tribe. Some examples of areas submitted as tribal subdivisions are:

Areas used by your tribe for the election of tribal government officials (e.g., districts or precincts used for the election of tribal council members);

Areas used by your tribal government for tax purposes;

Areas used by your tribal government for the provision of general services or specified services, such as:

water districts
health service areas
emergency service delivery areas (e.g., 911, fire, and/or police), or
grazing districts or range units

Historical or traditional areas recognized by your tribal government;

Local tribal community governments.

The Census Bureau requests that you add and/or revise your tribal subdivision boundaries on the BAS map(s) and complete the forms enclosed within this package. (If a full set of BAS maps has not been sent, please request them.) If your tribe delineated tribal subdivisions during a prior survey, tribal subdivision boundaries are symbolized on the enclosed BAS maps by a solid blue line. Before you add/or revise your tribal subdivision boundaries on the enclosed map(s), please note any changes to the boundary of your land base on the map(s) using the enclosed red pencil. Add and/or revise the boundaries of your tribal subdivisions on the enclosed BAS map(s) using the enclosed blue pencil. Additionally, the names and type (active or inactive) of your subdivisions are listed in Question 5 on the BAS-5B form. Please review and update this information.

If this is the first time you are providing tribal subdivisions, please add the boundaries on the BAS map(s) using the enclosed blue pencil. You must label each tribal subdivision on each map sheet with its name (e.g., “District 3,” “Arlee District,” “White Rock Chapter,” “Parmelee Community,” and so forth) and record the names, type, and status of each in Question 5 on the BAS-5B form. Examples of the tribal subdivisions include, but are not limited to: chapters, communities, districts, segments, and villages. Please note that tribal and tribal subdivision boundaries are not required to follow visible features (such as roads, rivers, or fence-lines). If you have any questions, please contact your Census Bureau Regional Office’s Geography staff at the telephone number shown on your enclosed BAS-5 form.

Criteria for Defining Tribal Subdivisions:

The delineation of tribal subdivisions is restricted to the area contained within your reservation(s) and/or associated off-reservation trust lands (land base).

There is no minimum population threshold for a tribal subdivision.

Tribal subdivisions should cover all, or most, of the tribe’s land base.

A tribal subdivision may be discontiguous.

Your tribe may designate only ONE type of tribal subdivision. If your tribe has more than one level of tribal subdivisions within its land base, the Census Bureau recommends delineating subdivisions corresponding to the lowest geographic level (i.e., those geographic areas containing the smallest area) of the tribe’s administrative hierarchy.

Tribal subdivisions should not be based solely on land ownership or other cadastral areas, nor should they consist of divisions based on the U.S. public land survey system of townships, ranges, and sections, if these areas have no governmental or administrative function for your tribe.

If you have any questions or need to order maps, please contact your Regional Office’s Geography staff at the telephone number shown on your enclosed BAS-5 form.

Example 2.2.6: Depicting a tribal subdivision

Example 2.2.6: Recording a tribal subdivision on the tribal BAS form

2.2.7 Feature modifications

This figure illustrates how to make feature modifications that may or may not be coincident with a boundary. Using the purple pencil, you will cross out the incorrect feature location with “Xs”. Draw the feature in the correct location, and print the name of the feature as shown in the figure below.

Example 2.2.7: Making a feature modification to a road that is partially coincident with a boundary

Note that adding features internal to the boundary of your reservation or off-reservation trust land is not required as part of the BAS. This is also true for other features such as streams, point features or areal features. If you choose to provide these, please see section 2.2.7 (above) through section 2.2.11.

2.2.8 Inserting point and area features

This figure illustrates how to insert point and/or area features, including mountains and airports. Using the purple pencil, draw the feature in the correct location, and print the name of the feature as shown in the figure below.

Example 2.2.8.1: Adding a mountain, point feature

Example 2.2.8.2: Adding an airport, area feature

2.2.9 Edits to street information

This figure illustrates how to add missing streets, new streets, alternate street names and address information.

When adding a missing street, new street, or other feature on the map, use the purple pencil to draw the feature and its name on the map, as shown in the figure below.

If you know an alternate street name, print the alternate in parentheses as shown in the following figure.

Provide the lowest or highest addresses that could be assigned to a road where the road intersects a boundary as shown in the following figure.

If the street has addresses, please provide the name of a source for those addresses on the Address Source Information Worksheet included on the last page of this guide.

Example 2.2.9: Adding a road feature with annotation, address breaks and an alternate road name

2.2.10 Adding feature names in a congested area

This figure illustrates how to add feature names to a congested area on the map. Using the purple pencil, draw the features onto the map. If the area is too congested to add all feature names on the map provided, number each feature and list this number and the corresponding feature name in the map margin or an uncongested spot close to the feature’s actual location as shown in the following figure. Please do not repeat numbers on a map sheet.

Example 2.2.10: Adding street name features in a congested area

2.2.11 Correcting feature location

This figure illustrates how to correct a feature location.

Using the purple pencil, cross out the existing feature on the map, and draw the feature in the correct location. Draw an arrow pointing to the correct feature location. Label the feature with the feature’s name.

Example 2.2.11: Correcting the location of a street feature

2.2.12 Correcting feature name

This figure illustrates how to correct a feature name. Using the purple pencil, draw a line through the incorrect feature name. Print the correct feature name next to the original name as shown in the following figure.

Example 2.2.12: Correcting a street feature name

2.2.13 Annotating address range breaks

The BAS maps show the last address stored in our geographic database for each street that crosses the boundary of your reservation. These addresses are shown because it is important that the Census Bureau assigns the correct addresses to each governmental unit. Since the BAS only targets addresses at the boundary, the Census Bureau has other operations that are designed to collect address information.^²

If any of the following circumstances exist, use the purple pencil to add the last address along a street where it intersects the current boundary:

Addition or deletion was reported
Our depiction of your boundary was corrected
A street was added that crossed a boundary
Our depiction of the address is incorrect

Example 2.2.13: Adding a street feature and annotating with the name and address breaks

2.2.14 Deleting a feature

This figure illustrates how to delete a feature. Delete only if a feature is nonexistent or if a street is impassable. Do not delete a street because your government is not responsible for maintaining it.

Mark the beginning and end of the base feature to be deleted with hatch (//) marks perpendicular to the feature as shown below. Cross out what is to be removed using a string of “Xs”.

Example 2.2.14: Deleting a street feature

2.2.15 Adding a cul-de-sac or circle

This figure shows how to correctly represent a cul-de-sac or circle with illustrations of each symbol and corresponding aerial photographs. The photographs are provided to show the difference between cul-de-sacs and circles. A cul-de-sac is paved, whereas, a circle has an area of unpaved ground within it.

To add a cul-de-sac or circle, draw the feature using the purple pencil following one of the sketches below. Print the name of the associated street leading to the cul-de-sac or circle.

Example 2.2.15: Adding cul-de-sac and circle features with annotations

2.2.16 Designating a geographic corridor to a street feature

This figure illustrates how to display a geographic corridor (a corridor that occurs on both sides of a road).

A geographic corridor is an area that only includes road surface and right-of-way and does not contain any structures addressed to either side of the road. The Census Bureau geocodes addresses based upon the centerline. There are two types of geographic corridors:

An area where only the road, or other feature, belongs to your reservation or off-reservation trust land
An area where a road, or other feature is not part of your reservation or off-reservation trust land

To indicate a geographic corridor on your map, use the red pencil to draw a line on each side of the road. Mark the beginning and end of each line with perpendicular hatch marks. Write the letters “GC” beside each line.

Example 2.2.16: Designating a geographic corridor to the north and south of the street feature

2.2.17 Designating a geographic offset to a street feature

This figure illustrates how to display a geographic offset (a corridor on one side of the road).

A geographic offset is an area claimed by an entity that is only on one side of the road and does not include any structures addressed to that side of the road. The Census Bureau geocodes addresses based on the centerline of roads. If your boundary is not coincident with the centerline but follows the parcel line, and the addresses along the road should be in your jurisdiction, you need to report a geographic offset. By coding the offset the addresses will be assigned to the correct geography.

To indicate a geographic offset on your map, use the red pencil to draw a line parallel to the road on the side where the offset exists. At the beginning and end of the offset draw double hatch marks. Write the word “Off” near to the line.

Example 2.2.17: Identifying a geographic offset to the north of the street feature

2.2.18 Unnamed roads

If you find unnamed road segments on the maps, please provide the road names, if known, using the purple pencil or label them as “PR” if these are unnamed private roads. Examples of private roads are driveways and unnamed roads in commercial or industrial parks.

Example 2.2.18: Adding unnamed road features with annotation

3.0 Signing the Updated Maps

For each map sheet that has changes, fill in the Signature Box on one copy of the map:

Print the date, your name, position and phone number
Sign your name

Example 3.0: Completing the signature box on the map sheet

Use the postage-paid envelope to return the set of signed tribal maps and the BAS form to the Census Bureau. If after reviewing the tribal BAS forms and maps it is determined that you do not have any changes to report, sign the “No Change” postcard and return it to the Census Bureau.

Appendices

Appendix 1: Paperwork Reduction Project

The Census Bureau estimates that the BAS review will take most respondents from 1 to 6 hours to complete. This includes the time needed to read the instructions, assemble materials, organize and review the information, and report any needed changes. This estimate is based on 80 percent of all areas having few or no changes. However, for areas with many changes it may take 20 hours or longer to complete the survey. Please send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to:

Source Evaluation Checklist

	YES	NO
Does the source contain the names and addresses for all street features affected by the boundary?
Does the source contain address range breaks where the streets intersect or meet with the boundary?
Does the source show which sides of the streets contain the even and odd addresses?
Are there other current map and address reference sources available for use by the Census Bureau?

1 Please note that the geography for all figures is for graphical purposes only and does not represent actual patterns on the ground.

2 If you have a reliable source for addresses within your jurisdiction and would be willing to share that information with the Census Bureau, we request that you fill out the Address Source Information Worksheet found on the last page of this guide. BAS staff will forward the updated form to the address update staff with the information you provide about the source. The correct assignment of addresses to jurisdictions is of primary importance to our censuses and surveys. If the street has addresses, please provide the name of a source for those addresses on the Address Source Information Worksheet. Provide the lowest or highest addresses that could be assigned to a road where the road intersects a boundary.
