The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

The Fair Housing Act Design Manual: A Manual to Assist Designers and Builders in Meeting the Accessibility Requirements of The Fair Housing Act provides clear and helpful guidance about ways to design and construct housing which complies with the Fair Housing Act. The manual provides direct information about the accessibility requirements of the Act, which must be incorporated into the design, and construction of multifamily housing covered by the Act. It carries out two statutory responsibilities: (1) to provide clear statement of HUD's interpretation of the accessibility requirements of the Act so that readers may know what actions on their part will provide them with a "safe harbor"; and (2) to provide guidance in the form of recommendations which, although not binding meet the Department's obligation to provide technical assistance on alternative accessibility approaches which will comply with the Act, but may exceed its minimal requirements. The latter information allows housing providers to choose among alternative and also provides persons with disabilities with information on accessible design approaches. The Manual clarifies what are requirements under the Act and what are HUD's technical assistance recommendations. The portions describing the requirements are clearly differentiated from the technical assistance recommendations.
