Public Building Commission of Chicago : iii iv : Public Building Commission of Chicago Letter from the Chairman As Chairman of the Public Building Commission, I welcome you to our first publication of Site Development Guidelines. The Guidelines serve as a comprehensive reference and education tool for site development of publicly funded projects, with a focus on responsible management and environmental stewardship. The site development surrounding public facilities plays a critical role in defining each building. By developing carefully designed plans for paving, landscaping, green roofs, lighting and stormwater management, we strengthen each facility and continue our commitment to making Chicago the greenest city in the nation. Our streamlined project oversight ensures high quality, low maintenance and environmentally sustainable facilities throughout Chicago. With guidance from the PBC Board of Commissioners, client agencies, consultants, and internal staff, PBC procedures continue to evolve and improve. As you read the Site Development Guidelines, please note that we will continue to update and inform you of any new and innovative strategies. Whether you are a client agency, a professional services consultant, or a citizen of Chicago, I believe you will find that the PBC’s commitment to high standards in all phases of development is central to the way we operate and to the long term beauty, durability and vitality of our public facilities. Sincerely, Richard M. Daley Chairman Public Building Commission of Chicago Public Building Commission of Chicago : v vi : Public Building Commission of Chicago Letter from the Executive Director The Public Building Commission (PBC) holds a unique role in shaping the City of Chicago, building its public facilities and infrastructure. The Site Development Guidelines are intended as a tool for professional service providers, builders and other staff working on behalf of the PBC and its clients. As an application of lessons learned and best practices, these guidelines will bring both quality and consistency to the process of site development and maintenance surrounding each of the public facilities we deliver. The PBC is responsible for a wide range of projects, from firehouses, fire houses and police stations to schools and libraries. Therefore, the importance of continuity and consistency of development and maintenance are paramount. The parameters described herein will be applied throughout Chicago on public development projects. It is for that reason that so many dedicated professionals, from both the public and private sectors, have worked hard to develop standards that will be applied in every stage of a project’s development, from zoning and site selection to the training of the people who will maintain a facility and its grounds. Responsible public development is the mission of the Public Building Commission. These guidelines exhibit our commitment to both economic sustainability and environmental sustainability in every project we take on. Noteworthy is our Landscape Design section, offering site elements key to responsible landscapes for public facilities. They encourage bio-diversity to mitigate the effects of invasive species. The plant selections are drought resistant, native to the area, require little maintenance to thrive, and provide year round aesthetic interest. Ornamental fencing protects the landscapes for future enjoyment and instructional signage is encouraged to engage and educate the community on plant species and sustainable features. Our commitment to the environment and to the exemplary stewardship of the public fund through the leadership and vision of the PBC’s Board Chairman, Mayor Richard M. Daley, whose is dedicated to making Chicago the greenest city in the nation. We are grateful for the opportunity to implement that laudable goal.
