Upper Ballard Pond (UBP) must be protected against all erosion and sediment impacts since it is not an ESC basin or measure. Plan notes, profiles, (text edit) revision request is based on RGA comment response to comment #4. RGA response is 3), and that Str. 148B (34.89 LF 15" DIA HDPE pipe, sheet 9) be placed prior to placing asphalt intermediate and surface asphalt courses on Belgrove St. Str -148, approved under block 28 -29B, road plan is essentially a temporary feature that changes with this plan. This is a recommendation.

Sediment basin (see WP0201500042, ). This is problematic. There is possibility future development of blocks 7, 6, 26, or 35 will require trap/basin in similar location (ref. WP0201400004, sheets 3, 9, 10). Construction of structures between inlet #223 and UBP (outfall) is contingent upon complete upslope stabilization of all areasiblocks draining to Str. #223 to ensure negligible sediment -laden runoff reaches Str. #223.

Sediment basin approved under WPO201400004/ proposed to be modified under WPO201500042), only pipe #223A may be shown as an outfall from Str. #223 (WPO201500042, sheet 3). Str. #223 is proposed to replace Ex. Str. 156A. Note: This topic was discussed in detail in email (J.
