Attachment 7- Site Based Stormwater Management Plan

 

MAINTENANCE OF CONTROL MEASURES

All erosion, sediment and drainage control measures need to be regularly
checked and maintained in good working order. Best practice includes
anticipation of potential risks and being prepared for abnormal
circumstances and emergencies. These measures include:

* — Stockpile extra sediment fence fabric and posts on-site to facilitate
emergency repairs.

¢ — Reapply crushed rock to the entry/exit pad (rumble pad) when
sediment build-up occurs.

¢ — Repair eroded drainage channels with rock, turf or erosion control
blankets or matting.

¢ — Ensure built-up sediment is removed at regular intervals from
sediment barriers.

* — Check and replace/repair sediment barriers daily if they are ripped,
damaged or no longer anchored.

DIVERSION OF UP-SLOPE WATER

¢ Where practicable, divert up-slope water around the disturbed area.
© — Stormwater can be diverted with the use of small turf or geotextile lined catch drains, or with the use of
diversion banks,

¢  Diverted stormwater should be discharged onto stable ground (for example turfed areas) and should not
be diverted into neighbouring properties unless written permission is obtained from the land owner(s).

_ EARLY ROOF WATER CONNECTION

¢ Temporary or permanent downpipes should be installed as soon as
practicable after the roof is laid.

¢ Early connection of roof water to the stormwater system will reduce site
wetness and the generation of on-site mud. This has been shown to
reduce downtime following storm events and decrease the average
building construction time.
