RE: Interstate Power Company Building, 1000 Main Street, Dubuque, Dubuque County
Dear Mayor Buol:
We are pleased to inform you that the above property located within your community was accepted for nomination to the
National Register of Historic Places by the State National Register Nominations Review Committee at its February 8, 2008
meeting. The final version was received and submitted to the National Park Service for final review and listing on the
National Register. It has been brought to our attention that not all property owners received notification of the proposed
National Register listing from our office. This letter is being provided to resolve this issue and give all property owners a
chance to comment or waive comment. We also must request a waiver of the comment period from the chief elected official.
We believe all property owners and the chief elected official are in favor of the listing of this property on the National
Register of Historic Places and would like to move forward with the process by proposing that these individuals sign a waiver
of the 30 day commenting period. If you are in agreement please sign the attached waiver and return the original to my
attention at State Historical Society of Iowa, 600 E. Locust, Des Moines, 50319. If you have the technology you can send a
copy either by fax (515/262-0502) or email (beth.foster@iowa.gov) and I will forward that to NPS for temporary
acknowledgement and then forward the hard copy with original signature on when I receive it.
The National Register is the Federal Government's official list of historic properties worthy of preservation. Listing in the
National Register provides recognition and assists in preserving the heritage of our Nation.
Listing in the National Register provides the following benefits to historic properties:
• 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 rehabilitation 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. Whether these provisions are advantageous to a property
owner is dependent upon the particular circumstances of the property and the owner. Because tax aspects outlined above
are complex, individuals should consult legal counsel or the appropriate local Internal Revenue Service office for
600 EAST LOCUST STREET, DES MoiNEs, IA 50319-0290 P: (515) 281-5111
assistance in determining the tax consequences of the above provisions. For further information, please refer to 36 CFR
67 and Treasury Regulation Sections 1.48-12 (ITCs) and 1.170A-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.
• 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 for a 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.
Owners of private properties nominated to the National Register of Historic Places have an opportunity to concur in or object
to listing in accord with the National Historic Preservation Act and 36 CFR 60. Any owner or partial owner of private
property who chooses to object to listing is required to submit to the State Historic Preservation Officer a notarized statement
certifying that the party is the sole or partial owner of the private property and objects to the listing. Each owner or partial
owner of private property has one vote regardless of what part of the property that party owns. If a majority of private
property owners object a property will not be listed; however, the State Historic Preservation Officer shall submit the
nomination to the Keeper of the National Register for a determination of eligibility of the property for listing in the National
Register. If the property is then determined eligible for listing, although not formally listed, Federal agencies will be required
to allow the Advisory Council on Historic Preservation an opportunity to comment before the agency may fund, license, or
assist a project which will affect the property.
Should you have any questions about the National Register of Historic Places, Tax Incentives or about this nomination in
particular, please feel free to contact me by telephone at 515-281-4137 or by e-mail at beth.foster@iowa.gov. You may find

Sincerely,

Barbara Mitchell
