I have a project, under the current condition, say there are 20% building, 50% of pavement for road and parking, and only 25% left for open space (greenfield) and 5% for wetland (excluding from greenfield for calculation?). Under the proposed condition, a parking garage will be built at one of the existing parking lot.
Since there is only 25% greenfield on site right now, before seeking option #1 or #2, we have to preserve and protect at least 40% of the greenfield, say keeping at least 25% x 40% = 10% preserved and protected. Would you please let me know if my understanding is correct?
If we go for option #2, I understood that the financial support is calculated for $0.40/SF for the entire area within the LEED boundary. This is one-time contribution. Am I right?
If we go for option #1, then we have to restore 30% of 20%+50% (previously disturbed area), in other word, reducing the proposed impervious area to less than 49% of the site. Would you please let me know if my understanding is correct? Of course, we have to meet all the soil criteria.
