H.R. 3100, San Antonio Missions National Historical Park Boundary Expansion Act

June 15, 2012
Cost Estimate


As ordered reported by the House Committee on Natural Resources on June 7, 2012

H.R. 3100 would expand the boundary of the San Antonio Missions National Historical Park in Texas to include approximately 151 additional acres. Of the proposed 151-acre expansion, 132 acres are currently owned by the National Park Service (NPS) or are being donated to the park. The remaining 19 acres would continue to be managed under a cooperative agreement with the city of San Antonio and Bexar County, which own the property.

Fourteen acres of the property owned by the city of San Antonio have environmental contamination. If those lands are included within the boundary of the park, the NPS would be responsible for the remediation of that contamination. Based on information from the NPS, CBO estimates that remediation work would cost around $9 million, subject to the availability of appropriated funds.

Based on information provided by the NPS, CBO estimates that implementing H.R. 3100 would have no other significant impacts on the federal budget. The NPS currently manages most of the land that would be added to the park, and CBO estimates that the legislation would not significantly affect operating costs. Enacting H.R. 3100 would not affect direct spending or revenues; therefore, pay-as-you-go procedures do not apply.

H.R. 3100 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act and would not affect the budgets of state, local, or tribal governments.

On December 20, 2011, CBO transmitted a cost estimate for S. 114, the San Antonio Missions National Historical Park Boundary Expansion Act of 2011, as ordered reported by the Senate Committee on Energy and Natural Resources on November 10, 2011. The estimated costs of the two bills differ for a number of reasons. H.R. 3100 would authorize lands to be acquired only by donation, whereas S. 114 would authorize the NPS to purchase additional land. Also, since the cost estimate for S. 114 was prepared, the NPS has been paying the operational costs (other than environmental remediation costs) of the proposed additional land, so the legislation would not add to those costs. Additionally, S. 114 would authorize a study of the suitability of adding other lands to the park, which H.R. 3100 would not authorize.
