1. Dispersal trench (detention outfall) should be moved east as much as possible away from the property line to
minimize any impact on WSDOT right-of-way and sispers as far as possible on the Jenna Lane parcels.
2. Acceptable material for detention pipe are as follows:
Metal:
ACSP — Aluminized Corrugated Steel Pipe (Type 2 meets AASTO designations M274 and M36)
ASRP - Aluminum Spiral Ribbed Pipe (16 gauge or better)
CAP —Corrugated Aluminum Pipe (16 gauge or better)
DIP — Ductile Iron Pipe (Class 50 or better)
Concrete:
PCP — Plain Concrete pipe
RCP — Reinforced Concrete Pipe
Plastic:
PVCP — Polyvinyl Chloride Pipe (SDR 35 or better)
CPEP — Corrugated Polyethylene Pipe (smooth interior wall, or N-12® pipe)
RPP- Ribbed Polyvinylchloride Pipe
Also, no geotechnical report was submitted. Does the detention system need buoyancy calculations or is the
groundwater well below the bottom of the proposed detention pipe?
3. The areas for BMP T5.13 Post -Construction Quality & Depth, should be called out on the plans .
