FAQs about SSp1 :

Am I exempt from this prerequisite if I have a zero-lot-line building? What if the site work is minimal due to the scope? What about a renovation? What if the excavation and foundation work is minimal due to the construction materials I am using?

What are BMPs for steep slopes?

I have a technical question about a specific control measure and whether LEED requires it. What guidance is available?

Is there a preferred method for documentation?

What suffices as far as a date-stamped photo?

Can I still earn the prerequisite if the project started considering LEED after work began?

CS-2009 SSp1:Construction Activity Pollution Prevention

Water filtration

How much filtration is required when discharging rainwater that contains suspended solids? We have some rainwater acumulation and we would like to know if a simple screening will be enough. For example will a piece of a not woven geotextile at the end of the piping retaining solids be enough?, or do we need to do something else? Any suggestion will be appreciated.
