FAQs about SSc3 :

Are any of the components of the SSc3 plan optional? What if no landscaping areas or planter boxes are in the LEED project boundary? What if I have a zero lot line property?

A pest control product we used is not on the San Francisco Pesticide Hazard Screening List, but I’m pretty certain that it qualifies as least toxic. What steps can I take to confirm this and document it for the LEED submittal?

Our project grounds are fully landscaped with established vegetation. What should I do for the erosion and sedimentation control plan?

There are no construction or renovation projects planned for our project building. Can I skip the erosion and sedimentation control plan for construction activities?

How do I document my project’s landscape waste diversion performance? We don’t divert 100% from landfills, but we do meet the 20% diversion threshold required by the credit.

EBOM-2009 SSc3:Integrated Pest Management, Erosion Control, and Landscape Management

Round-up

I'd like to confirm that Round-Up Pro (EPA # 524-475) is okay to use for weed control in sidewalk cracks. The only reference to weeds I can find is that the best practice is to hand-pull-is that the only option? In a hot/humid climate, fertilizer use is minimal to none because plants grow very easily, but weed control is a big concern. Are weed considered 'pests' and products must fall under SF Hazard criteria Tier 3?

The literal requirements of the credit focus mainly on animal and insect pests, but the credit intent is that non-chemical methods are used in lieu of herbicides wherever possible as well. The SF Hazard Screening List lists Roundup Pro (and it's active ingredient "glyphosate") as a Tier II product, therefore it would not be considered a least-toxic alternative. I'd suggest spending a bit of time researching non-chemical herbicides, as there are a number on the market, and use hand-pulling as your backup plan. Remember, if all else fails, you are allowed to use a non least-toxic product during your performance period, but you need to explain the least-toxic methods that were found to be ineffective before resorting to the toxic option.

Thanks Jason. I'd like to keep his open and ask if anyone out there (maybe a landscape vendor?) has a recommendation for non-chemical alternative to round-up? It's the one product I can't convince them to give-up, and I'd like to suggest an alternative.
