RE: Interstate Power Company Building, 1000 Main Street, Dubuque, Dubuque County
Dear Mayor Buol:
We are pleased to inform you that the above named property, which is located within your community,
was listed in the National Register of Historic Places effective June 26, 2008.
Listing in the National Register provides the following benefits:
Consideration in the planning for Federal, federally licensed, and federally assisted
projects. Section 106 of the National Historic Preservation Act of 1966 requires Federal
agencies allow the Advisory Council on Historic Preservation an opportunity to comment
on projects affecting historic properties listed in the National Register. For further
information please refer to 36 CFR 800.
• Eligibility for Federal tax benefits. If a property is listed in the National Register, certain
Federal tax provisions may apply. The Tax Reform Act of 1986 revises the historic
preservation tax incentives authorized by Congress in the Tax Reform Act of 1976, the
Revenue Act of 1978, the Tax Treatment Extension Act of 1980, the Economic Recovery
Tax Act of 1981, and Tax Reform Act of 1984, and as of January 1, 1987, provides for a
20 percent investment tax credit with a full adjustment to basis for rehabilitating historic
commercial, industrial, and rental residential buildings. The former 15 percent and 20
percent investment Tax Credits (ITCs) for rehabilitations of older commercial buildings
are combined into a single 10 percent ITC for commercial or industrial buildings built
before 1936. The Tax Treatment Extension Act of 1980 provides Federal tax deductions
for charitable contributions for conservation purposes of partial interests in historically
important land areas or structures. For further information please refer to 36 CFR 67 and
Treasury Regulation Sections 1.48-12 (ITCs) and L170A-14 (charitable contributions).
Consideration of historic values in the decision to issue a surface coal mining permit
where coal is located, in accord with the Surface Mining and Control Act of 1977. For
further information, please refer to 30 CFR 700 et seq.
600 EAST LOCUST STREET, DES MOINES, IA 50319-0290 P: (515) 281-5111
• Qualification for Federal and State grants for historic preservation when funds are
available.
• Eligibility for State Tax Credits for rehabilitation. Properties listed on the National Register,
eligible for listing on the National Register or Barns constructed before 1937 are eligible to apply
fora 25 percent state tax credit for rehabilitation. The cost of a 24-month qualified rehabilitation
project would exceed either $25,000 or 25 percent of the fair market value for a residential
property or barn less the land before rehabilitation. For commercial properties, the rehabilitation
project would exceed 50 percent of the assessed value of the property less the land before
rehabilitation -whichever is less. The State Historic Preservation office must approve the
rehabilitation work before an amount of tax credits will be reserved for your project. There are
limited credits available each year, so let us know if you want the application information.
