Local Government Infrastructure Financing Improvement Act of 1987

Local Government Infrastructure Financing Improvement Act of 1987 - Amends the Public Works and Economic Development Act of 1965 to direct the Secretary of Commerce to provide local governments technical assistance with respect to financing construction, repair, and expansion of public works facilities, including provision of information necessary to familiarize local governments about the use and availability of tax-exempt public works facility bonds for such financing.

Requires the Secretary to report biennially to specified congressional committees on local government public works financing practices.

Amends the Internal Revenue Code to: (1) raise from $5,000,000 to $25,000,000 the threshold amount of tax-exempt bonds that a small governmental unit may issue and still remain within the exception from arbitrage rebate requirements; and (2) increase from ten percent to 25 percent the amount of tax-exempt government bond proceeds that may be used by a nongovernmental entity for private purposes without triggering treatment of the bond issue as a taxable private activity bond. Limits the latter provision to governmental issuers whose reasonably anticipated amount of tax-exempt obligations to be issued during the calendar year is $25,000,000 or less. Caps at $25,000,000 the amount of bonds to which the issuer may apply the 25 percent private use test in any year.
