The 2020 Environmental Best Management Practices and Design Standards Manual was written in cooperation with multiple city departments to provide clear direction on standard operational procedures; to effectively communicate Parks & Community Services Department operational practices to the public; and to respond to regional, state and federal environmental issues. Proper care and maintenance, as well as the understanding of certain practices and systems, is essential in perpetuating the longevity and usefulness of city assets.
In order to continue to improve the standard of care and our maintenance practices, this manual is reviewed and revised every four years. Any changes, modifications or comments regarding these best management practices should be directed to Rick Bailey - ribailey@bellevuewa.gov or 425-452-6031.
The city has also developed Tree Pruning Guidelines ( PDF, Flipbook ) to inform property owners about appropriate tree maintenance practices that are allowed in geological hazard critical areas.
The Parks & Community Services Department’s mission is to build a healthy community through an integrated system of exceptional parks, natural areas, recreation, arts and culture and a broad base of community services. This mission is based on the Parks and Community Services Department’s philosophy to:
- Protect and preserve environmentally sensitive natural areas;
- Provide connections for an integrated open space system;
- Enhance the City’s visual character throughout the park system by perpetuating the “City in a Park” ideal;
- Acquire and develop park facilities to meet the present and future needs of the community; and to renovate or modify parks for optimum use of resources.
The following are lists of updated and current park and street tree/arterial landscape design standards available for individual download in PDF format. Please contact Rick Bailey at ribailey@bellevuewa.gov or 425-452-6031 if you would like to obtain an associated CAD file.
