cover with ½” hexbolts is not required.
5)Show a cleanout at the edge of easement.
6)Please note thatcleanouts must belocated within 2’ of the house, at any 90° bend, when there is less
than 3’ between two 45° bends, and when there is more than 100’ between cleanouts. Please show
cleanouts where needed.
7)Please show the invert elevations at the stub/mainand the house so that slope and coverage can be
verified. If the slope of the pipe exceeds 20% the pipe will need to be anchored.
STORM
The proposed stormwater management system could only bepartially reviewed because the infiltration
rates could not be verified due to a lack of information. Please see comments from Jerry Shuster below.
Additional comments will be provided once the infiltration rates have been verified.
1)Showthe overflow pathsfor the infiltration systems.
2)It appears that the surface water runoff from the driveway will be collected and discharged to two
separate systems.
a.Is the infiltration trench in the driveway and south of the property intended to be connected?
b.If the systems are not intended to be connected, please clearly show what portions of the
driveway will discharge to which system.
3)Please show the directional flow areas of the entire driveway, such that it is clear that the surface water
runoff will be collected and discharged to the onsite stormwater management system.
