The following information should be sent to the Division of Historical Resources (DHR) with the request for historic preservation review. The effectiveness and efficiency of the DHR's response will depend on the level of information submitted, especially as the DHR determines whether the applicant needs to obtain the services of professional preservation consultants to identify and evaluate properties in the area of impact.

(1) The names, addresses, and telephone numbers of the project sponsor and the principal contact person.

(2) The federal or state agency/program for which this review is required (if different from #1), and the permit or job reference number.

(3) A narrative description of the proposed undertaking (or copy of the application to the grantor agency or any other environmental review record, if available); the undertaking's area of potential effects (including secondary areas or impacts, such as borrow pits, changes in functional relationships between historic properties, etc.); and the nature and extent of any past development or disturbance on the subject property (including the location of existing utilities, previous landscape alterations, and when these changes were made).

(4) A photocopy or computer-generated image of the relevant portion of a USGS quadrangle map with the project area clearly identified.

(5) For ground-disturbing projects, a photocopy of the relevant portion of a soils map and/or soil boring log.

(6) A large-scale map, diagram, or site plan, showing the project and site in relationship to their immediate setting. The drawing should indicate compass orientation, contours, general soil types, distances to surface water, presence of wetlands, and proximity to roads. If any existing structures, dams, canals, bridges, foundations, ruins, old wells, cellar holes, stone walls, trails, and specialized uses such as dump sites, etc., are present, their locations should be shown. The type of any known past disturbances or alterations of the site such as paving, filling, grading, excavation, mining, cultivation, demolition of structures, etc., should be indicated.

(7a) For projects involving a single building, a completed NHDHR Individual Inventory Form. For buildings that are more than fifty years old, the DHR recommends that this step be contracted out to a consulting architectural historian.

(7b) For projects involving more than one building, a target area, or projects on undeveloped land, a completed NHDHR Area Form. In addition, complete the first two pages of a NHDHR Individual Inventory Form for each building (old or new) in the project area. Instructions for completing the inventory forms and blank forms are available on our web site. However, as with step 7a, the DHR recommends that this step be contracted out to a consulting architectural historian.

(8a) If the project is for new construction, sketch plans and elevations should be submitted (if they are available).

(8b) If the project involves rehabilitation, demolition, additions, or alterations to existing structures, in addition to the sketch plans and elevations, the following items should also be submitted:

(1) A description of the work to be done.

(2) A copy of outline or preliminary specifications (if available).

(3) Photos of the portion/s of the structure/s where rehabilitation, demolition, additions, or alterations are to occur. Also provide photos of any doors, windows, trim, interiors, or other building features that are to be altered or replaced. Unlike the photos for the DHR Inventory Forms, which MUST be black/white for longevity, these review photos may be either 35mm black/white or color prints. Polaroids or other "instant prints" are NOT ACCEPTABLE.

Any rehabilitation work done on historic structures-including additions or alterations-must conform to The Secretary of the Interior's Standards for Treatment of Historic Properties (rev. 1995), generally the standard for "rehabilitation." More information on these Standards is available at http://www.nps.gov/history/hps/tps/standguide/. A booklet describing the standards, with do/don't guidelines, is available from the Division of Historical Resources. The DHR also has a variety of publications and fact sheets on technical preservation topics, which are available on request; contact the DHR for a subject list. The National Park Service has also published a good deal of online information on caring for historic buildings; links begin at http://www.nps.gov/history/hps/tps/online_ed.htm.

Treatment of building materials and components should be in accordance with National Park Service technical recommendations in the Preservation Briefs series. Ask the DHR for a list of current titles or go online at http://www.nps.gov/history/hps/tps/briefs/presbhom.htm.

All items and supporting documentation submitted with a review request, including photographs and publications, must be retained by the Division of Historical Resources as part of its review records. Items to be kept confidential should be clearly identified.
