This series consists of project files spanning almost the entire length of Simonds' career. A majority of the projects were undertaken in Pennsylvania, and a large percentage of these were completed in and around Pittsburgh where all of the Simonds partnerships were based. Some of Simonds' more significant projects are represented, including the Chicago Botanic Garden, Equitable Plaza and Mellon Square in Pittsburgh, the Virginia Outdoor Recreation Study, the Pittsburgh Aviary, Interstate 66 in Virginia, and the Army Outdoor Recreation Facilities Manual. Note that the Florida project files have been separated from this series and placed in the "Professional Projects - Florida" series.

The project files typically contain correspondence, meeting minutes, research and background material, notes, invoices, and other documents generated during the design and execution of the projects. Files are arranged alphabetically. For a number of the files within this group the original project numbers, as assigned by the Simonds partnerships, are included in the folder titles. For a list of these project numbers, refer to the "Biographical Information and Miscellaneous Material" series. Note that photographs, drawings and renderings originally found in these files have been transferred to "Drawings and Renderings" series for purposes of preservation and access.

This series consists of project files primarily dating from the mid-1980s when Simonds retired from the EPD firm and continued to work as a consultant. Simonds served as consultant on several other projects throughout his career, many of which are included in the Professional Projects series, but this group of files were identified by him as consultation work completed after retirement and are separated for this reason. The most notable consultation project in this series, comprising the bulk of the files in the series, is the Paris Pike Bluegrass project in Lexington, Kentucky.

The consultation project files typically contain correspondence, meeting minutes, research and background material, notes, invoices, and other documents generated during the design and execution of the projects. Files are arranged alphabetically. Note that photographs, drawings, and renderings originally found in these files have been transferred to other series in the collection for purposes of preservation and access.

This series consists of project files for the planning projects undertaken by Simonds in Florida. Over a period of 25-30 years, beginning in the late 1950s, Simonds and/or the EPD firm were planners of record for approximately twenty major Florida communities, including Miami Lakes, Fisher Island, Weston, Gateway, West Lake, and Pelican Bay. Simonds considered South Florida with its booming development to be the perfect region for he and the firm to implement their ideas of broad-scale comprehensive land use planning. The partnership established a second office in Miami Lakes, the first of many Florida new towns planned by Simonds and his partners.

The project files typically contain correspondence, meeting minutes, research and background material, notes, invoices, and other documents generated during the design and execution of the Florida projects. Files are arranged alphabetically, primarily listing the county first, followed by the project and/or city name. For several files within this group the original project numbers, as assigned by the Simonds partnerships, are included in the folder titles. For a list of these project numbers, refer to the "Biographical Information and Miscellaneous Material" series. Note that photographs, drawings, and renderings originally found in these files have been transferred to other series in the collection for purposes of preservation and access.

This series consists of Simonds' personal and professional correspondence spanning over 60 years of his life. Of particular interest are files containing correspondence with colleagues such as Harold Wagner and Garrett Eckbo, as well as Florida Governor and Senator Bob Graham, with whom Simonds discussed managed growth and environmentally-sound planning in Florida. The majority of the files are arranged alphabetically according to the name of the correspondent or the subject. Within this alphabetical arrangement, the personal and miscellaneous correspondence files are arranged chronologically. Note that correspondence exists throughout the collection in other series, particularly in the Professional Projects files, but the files in this series were identified by Simonds as correspondence and filed separately from other materials.

This series consists of speeches presented by Simonds over a period of almost 50 years. Several of the speeches were given at conferences or meetings, including ASLA and IFLA, and at universities and colleges. In addition, several addresses were related to the projects undertaken by Simonds and his partnerships, including the Chicago Botanic Garden, Miami Lakes and Saga Bay in Florida, and I-66 in Virginia. Of particular interest is a 1995 speech entitled, "A 50-Year Retrospective: Scope of the Profession - Typical Projects of Simonds and Simonds; Collins, Simonds and Simonds; EPD; and J.O. Simonds."

Files are arranged chronologically. Note that Simonds maintained two groups of speech files during his life: the chronological speeches in this series and the educational lectures found in the "Lectures and Speeches Used in Teaching" series.

This series consists of material pertaining to Simonds' service in ASLA, the national organization for landscape architects in America. In addition to correspondence and meeting papers, the files include bulletins and newsletters, and information pertaining to the ASLA Foundation. Of particular interest are a "Report on the Profession of Landscape Architecture" produced by a committee chaired by Simonds, the association's 1999 Centennial Celebration, and Simonds' publication, Lessons. Files are arranged alphabetically.

This small series is comprised of materials pertaining to Simonds' service on various committees and task forces throughout his career. Included are the Interprofessional Council on Environmental Design (ICED), the Florida Governor's Resource Management Task Force, and the White House Conference on Natural Beauty during the Johnson administration. Files are arranged alphabetically. For Simonds' service in ASLA, refer to the "American Society of Landscape Architects" series in this collection.

This series consists of manuscripts, galley proofs, correspondence, drawings, notes, and other materials pertaining to the first three editions of Landscape Architecture. First published in 1961, with revised editions in 1983 and 1998, it has been one of the primary texts used in landscape architecture education for several decades. Simonds was working on a fourth edition at the time of his death in 2005. Taken as a whole, the files give insight into Simonds' creative process, providing evidence of his selection of photographs, his use of quotations and "nuggets", the original illustrations and drawings he created for the publications, and his revisions to the text itself.

Files are arranged alphabetically for each edition of the publication. Note that the published monographs for this title, including foreign translations, can be found in the "Writings - Reports and Publications" series, and oversize materials can be found in the "Drawings, Renderings, and Miscellaneous Flat Storage" series.
