In addition:

Where a high water table is anticipated or observed, or has been documented in the soil boring report, or where specifically recommended by the Geotechnical Engineer in the required geotechnical/soil boring report, provide subsurface drain tile or other drainage system in strict accordance with the Geotechnical Engineer's recommendations, to divert underground water away from the structure. Coordinate these requirements with those Green Communities Criteria 7-11a and 7-11b as modified herewith.
