PURPOSE OF THE BILL

The purpose of H.R. 5110 is to modify the boundary of the Casa 

Grande Ruins National Monument. 

BACKGROUND AND NEED FOR LEGISLATION

The Casa Grande Ruins Reservation was proclaimed as the 

United States’ first archaeological preserve on June 22, 1892; the 

site was redesignated as a national monument on August 13, 1918. 

The monument preserves one of the finest architectural examples 

of 13th and 14th century Hohokam culture in the Southwest. The 

core of the monument is a massive, four-story earthen walled 

house, one of the largest prehistoric structures ever found in North 

America. Archeologists have discovered evidence that the ancient 

Sonoran Desert people who built the ‘‘casa grande’’ also developed 

wide-scale irrigation farming and extensive trade connections 

which lasted over a thousand years, until around 1450. 

The 472 acres included within the current monument represent 

only part of that community. A 2003 National Park Service (NPS) 

report identified seven parcels for potential addition to the monuVerDate Mar 15 2010 20:35 Sep 17, 2010 Jkt 089006 PO 00000 Frm 00002 Fmt 6659 Sfmt 6602 E:\HR\OC\HR598.XXX HR598

ment, including the 200-acre, state-owned Adamsville tract, a large 

village site with ball courts located two miles upstream from Casa 

Grande that is already listed on the National Register of Historic 

Places. Two other large tracts adjacent to the current monument 

both include the remains of residential neighborhoods, cemeteries, 

large roasting pits, refuse pits, and portions of the extensive canal 

system that encircled the community. 

H.R. 5110 authorizes the acquisition of all three properties ‘‘by 

donation, exchange, or purchase with donated or appropriated 

funds from willing owners only.’’ The bill also transfers two small 

parcels—totaling 11.2 acres and currently owned by other federal 

agencies—into the monument. The bill would add 415 acres to the 

monument in total. Additionally, H.R. 5110 transfers another 3.5 

acres that are currently part of the monument to the Bureau of Indian Affairs to correct an unintentional trespass on the southern 

boundary of the monument and allow for the widening and paving 

of the San Carlos Irrigation Project’s Pima Lateral Canal, a tribal 

water project. 

Finally, the bill directs the Secretary to conduct a study to identify additional lands in the area that might be appropriate additions to the monument. The study would examine properties on the 

north side of the prehistoric canal not assessed in the 2003 NPS 

study, which according to local archaeological groups include civic 

plazas, adobe-walled compounds, ball court villages, smaller clusters of houses, irrigated fields and rock-mulch agricultural features 

indicative of dryland farming. 

COMMITTEE ACTION

H.R. 5110 was introduced by Representative Ann Kirkpatrick 

(D–AZ) on March 11, 2010. The bill was referred to the Committee 

on Natural Resources, and within the Committee to the Subcommittee on National Parks, Forests and Public Lands. At a June 

10, 2010, hearing before the Subcommittee, a representative of the 

Department of the Interior testified in favor of the bill but requested it be amended to require the standard three years after 

funding is appropriated for completion of the study. 

On July 22, 2010, the Subcommittee was discharged from further 

consideration of H.R. 5110 and the full Natural Resources Committee met to consider the bill. Subcommittee Chairman Rau ́l 

Grijalva (D–AZ) offered an amendment in the nature of a substitute to set the length of the study at three years, as requested 

by the Department of the Interior. The amendment in the nature 

of a substitute also strikes the findings section of the original bill 

and makes several technical corrections. 

Subcommittee Ranking Member Rob Bishop (R–UT) offered an 

amendment to the amendment in the nature of a substitute to require that the three properties authorized for acquisition be acquired ‘‘only by donation from willing owners.’’ The amendment 

was not agreed to by voice vote. 

The amendment in the nature of a substitute was then agreed 

to by voice vote. The bill, as amended, was then ordered favorably 

reported to the House of Representatives by voice vote.

COMMITTEE OVERSIGHT FINDINGS AND RECOMMENDATIONS

Regarding clause 2(b)(1) of rule X and clause 3(c)(1) of rule XIII 

of the Rules of the House of Representatives, the Committee on 

Natural Resources’ oversight findings and recommendations are reflected in the body of this report. 

CONSTITUTIONAL AUTHORITY STATEMENT

Article I, section 8 and Article IV, section 3 of the Constitution 

of the United States grants Congress the authority to enact this 

bill. 

COMPLIANCE WITH HOUSE RULE XIII

1. Cost of Legislation. Clause 3(d)(2) of rule XIII of the Rules of 

the House of Representatives requires an estimate and a comparison by the Committee of the costs which would be incurred in carrying out this bill. However, clause 3(d)(3)(B) of that rule provides 

that this requirement does not apply when the Committee has included in its report a timely submitted cost estimate of the bill prepared by the Director of the Congressional Budget Office under section 402 of the Congressional Budget Act of 1974. 

2. Congressional Budget Act. As required by clause 3(c)(2) of rule 

XIII of the Rules of the House of Representatives and section 

308(a) of the Congressional Budget Act of 1974, this bill does not 

contain any new budget authority, spending authority, credit authority, or an increase or decrease in revenues or tax expenditures. 

3. General Performance Goals and Objectives. As required by 

clause 3(c)(4) of rule XIII, the general performance goal or objective 

of this bill, as ordered reported, is to modify the boundary of the 

Casa Grande Ruins National Monument. 

4. Congressional Budget Office Cost Estimate. Under clause 

3(c)(3) of rule XIII of the Rules of the House of Representatives and 

section 403 of the Congressional Budget Act of 1974, the Committee has received the following cost estimate for this bill from the 

Director of the Congressional Budget Office: 

H.R. 5110—Casa Grande Ruins National Monument Boundary 

Modification Act of 2010 

H.R. 5110 would authorize the Department of the Interior (DOI) 

to expand the boundary of the Casa Grande Ruins National Monument in Arizona by 417 acres. The bill also would authorize DOI 

to conduct a study to identify other potential adjustments to the 

boundary. CBO estimates that implementing H.R. 5110 would cost 

$7 million over the 2011–2015 period, assuming appropriation of 

the necessary amounts. Enacting this legislation would not affect 

direct spending or revenues; therefore, pay-as-you-go procedures do 

not apply. 

H.R. 5110 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act and would 

impose no costs on state, local, or tribal governments. 

Under the bill, DOI would be authorized to acquire 417 acres of 

land through donation, exchange, or purchase (using donated or appropriated funds) to expand the boundary of the monument. About 

205 acres of that land is owned by private entities, of which CBO 

expects roughly two-thirds would be acquired through purchase. 


hsrobinson on DSK69SOYB1PROD with HEARING
5 

About 200 acres of land is owned by the state of Arizona and would 

most likely be jointly administered by the state and the federal 

government (as authorized by the bill) over the next few years. 

Other land that would be added to the monument is currently administered by the Bureau of Land Management and the Bureau of 

Indian Affairs. The legislation would transfer administrative jurisdiction of that land to the National Park Service. Based on information from DOI, CBO estimates that land acquisition costs would 

total $6 million; however, actual costs would vary depending on the 

amount of land acquired by exchange or donation and market conditions at the time of any purchase. 

H.R. 5110 also would direct DOI to report to the Congress within 

three years whether other pieces of land should be included within 

the monument boundary. Based on information from DOI, CBO estimates that the cost of this study, as well as the cost of administering land acquired under the bill, would total about $1 million 

over the next five years. 

The CBO staff contact for this estimate is Daniel Hoople. The estimate was approved by Theresa Gullo, Deputy Assistant Director 

for Budget Analysis. 

COMPLIANCE WITH PUBLIC LAW 104–4

This bill contains no unfunded mandates. 

EARMARK STATEMENT

H.R. 5110 does not contain any congressional earmarks, limited 

tax benefits, or limited tariff benefits as defined in clause 9 of rule 

XXI. 

PREEMPTION OF STATE, LOCAL OR TRIBAL LAW

This bill is not intended to preempt any State, local or tribal law. 

CHANGES IN EXISTING LAW

If enacted, this bill would make no changes in existing law.
