Please make the following two corrections to the "BMP Planting/Sodding Notes"
on Sheet C4.2:
The vegetation in the bioretention cell may not be fertilized on a regular
basis. Only a one-time application of fertilizer to establish the sod is
allowed.
b. The application of herbicide in a bioretention cell should be avoided.
2. Please conduct a field test to determine the SHWT in the vicinity of the proposed
bioretention cell. If the SHWT is greater than two feet beneath the invert of the
bioretention cell, then show the correct elevation in the "Bioretention Filter Media
Cross-Section" on Sheet 4.2. If the SHWT is less than two feet beneath the invert
of the bioretention cell, then you must either redesign the cell to provide greater
separation or select a more appropriate BMP for the site.
