As part of this credit, LEED Canada 2009 requires the owner to implement a management plan to minimize pollution and eutrophication of waterways from excess nutrient pollutants such as nitrogen and phosphorus. My civil engineer who had agreed to provide this initially is no longer answering my emails. As such I am attempting to write this myself. My site is a commercial office building on a sea of parking with a cistern, inimal landscaping and permeable pavers at the low end. My plan addresses the cleaning agent for the building exterior meeting Greenseal or Ecologo annual testing of soil (for nutrient levels) followed by aeration and minimal fertilizers on sod. Is this adequate?

The requirements for LEED credit SSc6.2: Stormwater Management, Treatment, are to construct a stormwater treatment system designed to remove 80% of the average annual post-development total suspended solids (TSS) and 40% of the average annual post-development total phosphorous (TP).
To demonstrate compliance you are definitely on the right track. Be sure to indicate the phosphorous content of all fertilizer to be < 1%. Also indicate the products, equipment and services for all sodding work needed on the project over its life, including sched, maintenance, materials and how the work will be carried out. Be sure to have signed documentation from your landscaping contractor exemplifying that they understood how work is to be carried out in order to achieve the credit.
I would also suggest product sheets for you permeable paver, cistern and a list of the greenseal/ecologo products to be used.
See CIR#265 for a useful Canadian specific question/answer. The submission date is May 2, 2008, but it is still relevant.
Hope this helps!
