Stormwater Report and Plan: Consultant Stormwater Engineer review comments.
1.The plans and report for the subject property dated November 5, 2015 proposed a total of 4,114
square feet of new plus replaced impervious surface, qualifying the project as a Category 1 Small
Site Project. The plans and report for the subject property dated June 29, 2016 propose a total of
6,507 of new impervious surface, as well as a replaced impervious patio (unknown area), qualifying
the project as a Category 2 Small Site Project. Please update the report to address the minimum
requirements associated with a Category 2 Small Site Project, and quantify each new and replaced
impervious surface area.
2.The proposed infiltration facility is 28” deep. City of Edmonds Handout #E72D states that for
Category 2 small sites, borings and test pits shall extend 5 feet below the bottom of the facility. The
soils report (Drainfield Designs, 6/16/16) includes descriptions of 3 soil logs indicating that
explorations extended 48-65 inches below grade. Please submit soil data for soil at depths extending
at least 5 feet below the infiltration facility, within the proposed footprint of the infiltration facility.
Please define any acronyms included in the descriptions.
3.The soils report (Drainfield Designs, 6/16/16) includes descriptions of 3 soil logs with brief
statements of soil classification. Please follow one of the approved methods for determining design
infiltration rates listed in City of Edmonds Handout #E72D Requirements for Establishing Design
Infiltration Rates (USDA Textural Classification or Modified PIT).
Please resubmit 3 copies of the revised plans/documents to a Development Services Coordinator. Please
contact me at 425-771-0220 if you have specific questions regarding these plan corrections.
