Calculate the rough site area that you’ll need to restore. Is 50% of your site (minus building footprint) or 20% of the total site (including building footprint) larger? Whichever is larger, you will need to restore an area of that size. Will this be feasible under the rough design? If you have a small site with a large building footprint, you may not be able to achieve the requirement.
Create a site plan with the required buffer areas (see credit language). You may decide to alter the site plan to accommodate the designated boundary of site disturbance. For example, you may find that keeping sidewalks (which have a 10-foot buffer) within the 40-foot buffer of the building when possible will make sidewalk construction easier, because construction vehicles will have more room to maneuver.
Define the conditions under which your facility will resort to using toxic pesticides—for example, an infestation that poses a threat to the safety or well-being of human occupants.
Use the 2007 San Francisco Pesticide Hazard Screening List(see Resources) as your guide to determining if the chemical pesticides you use on your site are considered least-toxic or if they will require universal notification prior to administration.
