Hello All,

I am working on an urban redevelopment project that was not designated as a zero lot line. We are proposing a rainwater harvesting system for building re-use and irrigation. For the 90th percentile storm, we need to capture approximately 4,000 CF of rainwater and are cisterns have about 7,000 CF of capacity. However, we are only able to capture about 85% of our LEED boundary as we have a section of sidewalk and boulevard that will directly drain into the adjacent street. Does this mean we do not get any of the credits because we are not managing 100% of the design storms as there is some direct runoff? Has anyone ran into this before? I imagine I'm not the only one who hasnt been able to capture 100% of the site.
