During review of the subject submittal it was found that the following information, corrections, or
clarifications will need to be addressed:
1.Provide section view of storm detention system and water service and side sewer crossings.
Response comments received 2/3/06 note there are no crossings, so no section provided.
o
The drainage plan dated 11/23/05 showed both the water and sewer crossing the storm detention
o
pipe.
The drainage plan dated 2/3/06 does not show the storm detention pipe at all. The storm
o
detention system must be shown on the drainage plan and a section view is required if there are
in fact utility crossings.
2.Please submit 3 copies of the Detention System Worksheet. This worksheet can be found in the Storm
Water Management Handout #E72 (attached).
Only two copies of the detention system worksheet were submitted, however this worksheet can
o
no longer be used, see note below in item #3.
3.The drainage plan indicates the surface water runoff from the roof over the existing residence will drain to the
new detention system. The detention system has only been sized for the new impervious area. Either
separate the impervious areas or resize the detention system accordingly. If the impervious area exceeds
5000 sf the detention system must be designed and stamped by a licensed engineer.
Detention is now being sized for over 5000 square feet of impervious area and the City’s standard
o
detention system worksheet can no longer be used. The storm detention system must be designed
and stamped by a licensed engineer.
4.Provide RIM and invert elevations at all CB’s, including the CB in the right-of-way.
Response comments received 2/3/06 note RIM at street @100 assumed, invert per City Planning.
o
As part of the submittal requirements for this plan review, you are required to submit RIM and
o
invert elevations for the catch basin in the City right-of-way as well as for the catch basins
installed as part of the storm detention system.
5.Clearly indicate which portion of the driveway is new (proposed) and which portion is existing.
How will the driveway surface water runoff for the new driveway be collected and distributed to
o
the storm detention system?

9.Provide finished floor and bottom of footing elevations on the grading plan. This information will be used to
verify grading calculations. Please note that grading in excess of 500cy will require SEPA.
Using the bottom of footing elevations provided, grading for the addition has been calculated to
o
be in excess of 500cy. About 470cy of cut has been calculated for the garage alone. This
calculation was derived from using the bottom of footing elevation provided of 106 and
topography contours which indicate original grades from 130 to 114.
Grading in excess of 500cy requires SEPA. Please contact Gina Coccia, Planner for more
o
information on the SEPA process.
