7)Per Jerry Shuster, City of Edmonds Storm Water Engineer, please provide elevations for the “Seasonal High
Ground Water” table within the infiltration gallery section details. This is to ensure that the contractor will
know the limits of the bottom of the galleries and the required separation (1’ minimum).
8)For information, this site does fall under a Small Site project Category 2, due to the total “new impervious
surface area” of 5000 sf, see Handout E72, Figure E for the definition of “new impervious surfaces” &
Figure B for Project Classification. Per Jerry Shuster, sizing factor for both Category 1 & Category 2 Site
Projects are the same, it will not impact the sizing. The submitted Drainage Report Small Site Project
Category has been redlined to reflect a Category 2 site.
9)Please call out material for the storm tightline.
10)If footing drains arerequired, please show them on the Drainage Plan, as well as where the footings will
drain.
11)Please provide elevations for the below listed.
a.Sewer invert elevations and slope.
b.Rim and invert elevations for yard drains and cleanouts.
12)Pollution generating impervious surfaces (PGIS) is those impervious surfaces considered to be a significant
source of pollutants in stormwater runoff. For a single family home this most applies to vehicular driving
surfaces, i.e. driveways. Please correct the “Impervious Area Summary Table” to limit the PGIS to just the
driveway surface area (currently listed as 2000 sf of PGIS), add the difference to the new NPGIS or you can
eliminate the table from the site plan. The city provided Impervious Surface Table is correct, displaying a
total new impervious surface area of 5,804 sf.
th
April 17–The impervious surface areas are inconsistent on the submitted sheet set 1-3 of 5, provided
by Omega Eng.New impervious areas areshown as5,804 sf and 5,363 sf.The submitted Drainage
Report reflects new impervious surfaces of 5,363 sf.
Please update and re-submit the 5 page sheet set and Drainage Report,accounting for the driveway
turn around, impervious surface numbers and the infiltration system.
13)Per Edmonds Community Development Code 18.80.060C, the driveway approach must be constructed with
asphalt up to the property line. Please show this on the site plans.
th
April 17–Comment above was specific to the driveway approachfor sheet 1& 5 of 5 submitted by
Omega Eng. Please label the paved surfaces asasphalt or concrete.
14)The driveway approach width for a two car garage shall not exceed 24’, see Standard Detail E-2.26.
Regarding the proposed walkway/driveway, it would be ok to have a concrete walkway from the property
lineto the house entrance separating the driveway and walkway in order to meet the city driveway approach
standard, as well as to minimize impervious surfaces. Another option to meeting city standards would be to
widen the driveway outside of the right of way starting at the property line.
th
April 17–Please show the driveway turn around on sheets 1& 3-5as shown on the Plot Plan. Please
make sure all impervious surface tables are consistent.
th
15)April 17–Please add a note: Existingdriveway to be removed and landscaped.
Please resubmit 3 copies of the revised plans/documents to a Development Services Coordinator.Please
