Green infrastructure (GI) enhances the natural environment to manage rainwater where it falls, allowing water to soak into the ground, evaporate into the air or collect in storage units. Examples of GI include porous asphalt, rain gardens, bioswales, trees, and green roofs, among many other green technologies .
As with traditional infrastructure, GI requires regular operations and maintenance (O&M) activities to ensure proper functionality. The City’s Green Infrastructure O&M Plan serves as a reference for City field staff, other City agencies and partners, GI designers, the development community, and interested members of the public.
Monitoring for Improved Performance
By monitoring existing green infrastructure sites, the City is evaluating the performance of green infrastructure and gathering lessons learned regarding GI siting, design, construction, and maintenance so that we can continually improve our program. For more on the City’s GI Monitoring program, see the GI Monitoring Plan (2019) .
GREEN IT! LANCASTER
The City’s investments in green infrastructure are guided by Green It! Lancaster, a 25-year plan for improving water quality in the Conestoga River, reducing pollution and excessive flows from our MS4 and Combined Sewer System, achieving cost effective compliance with regulatory obligations, and reinforcing our position as a national and statewide leader.
