developer to restore the 8” line to current City Standards. Please note as such on the plans.
4)Please show the sewer connection (wye) to the existing 8” sewer line forthe subject parcel a minimum
of 3’ from the cleanout (north).
5)Please note the pipe material and size.
6)Please add a note that the 6” cleanout at the property linewill have a12” cast iron lamphole cover with
½” hexbolts.

a.Please add a note that a 1” meter is to be installed.
b.Please note that the water service lineis to1 ½”.
c.Please note that tracer wire will be added to the water service line.
STORM
1)Please show the impervious surface calculations as shown below:
LineTypeArea (square feet)
1.Non-Regulated
ExemptRegulated
2.Replaced
3.New (Post 1977)+
Total Regulated Impervious Area
4.=
Mitigation required if in excess of 2000sf
5.Total Area Mitigated by Existing Stormwater Management System(s)-
=
6.Regulated Area Not Yet Mitigated
=
7.Area Proposed to be Mitigated by Low Impact Development Techniques
=
8.Area Proposed to be Mitigated through Conventional SWM Techniques
2)Per a phone conversation with you, you stated that a portion of the impervious surface water runoff
going to the stormwater management system was from offsite. However, when scaling your plans it
appears that the total impervious surface number you provided (5456) is only what is onsite.
a.Please check to make sure your numbers/plans are accurate.
b.If runoff from the driveway adjacent to the property to the east will be collected and discharged
to the proposed stormwater management system please include the square footage in your
impervious surface calculations.
