Limit Boundary -

It sounds to me like this is reasonable.However, why would you not implement an ESC plan on the whole site?

Hello Tristan,

I am particularly interested in this question since I have a similar situation myself. The problem of implementing an ESC plan in the whole site in a situation like this is cost.

So what do you think? Will the prerrequisite sill be met or not with the ESC measures implemented only in a portion of a site?

You would have to meet the ESC measures on the entire LEED Project Boundary, and the LEED boundary has to be set to take in the scope of work relative to the LEED project. There is more info on that in the Reference Guide and Minimum Program Requirements.I would question whether it's really within the spirit of LEED to only do the minimum requirement here. In the U.S.., this prerequisite is generally standard practice, anyway. Can you try to do the plan on all of the affected site area?

We do think the same way. Some of the measures can be full implemented, such as;

1. No runoff is leaving the site
2. All stormwater is being filtered
3. Due to regular weather conditions all soil is wet mostly of the time so no dust is airborne
4. All trucks are covering debris comming out of the site
5. Streets surrounding the site are always free of mud/dirt

But that's about it.

What if dust prevention and stormwater runnoff mitigation measures are fully implemented at the site (they are standard practice in Panama), however the slope protection is just covered within the LEED project boundary.

Like i mentioned before, it is a matter of cost. I need to be 100% sure the prerrequisite will be met.

Thank you for your help tristan.

I think it's a bad idea and not what LEED is about to only use slope protection within the LEED project boundary. Also, I am not clear on why you would have disturbed site area that is not within the LEED boundary.

Ok, I think I didn't explain myself properly. First of all I would like to start by defining the LEED Project Building then try to define what the LEED Project Boundary will be (I need some help in this), this is a particular situation that I think will be of interest by others.

This is the project:
-Zero lot line mixed use project with three buildings and underground parking.
-Only one of these building will apply for LEED certification.
-The project will be built by phases, being phase 1 the construction of the LEED project building and the entire uderground parking lot that will be shared with all buildings (LEED and not LEED buildings), this phase 1 is defined by a construction joint.
-The LEED building will have separate MEP from the rest of the buildings

My first question is:

1. ¿How would you draw the LEED Boundary in this case? My assumption is that, since the LEED Project Building will be delimited by the construction joint and will have independent MEP, this joint will be our LEED Project Boundary. ¿Will this be acceptable?

Yes, I would say that definition of the LEED boundary makes sense.
