GENERAL
1) The plans provided do not clearly show the limits of the existing driveway. It is understood
that the current conditions include additional gravel area beyond what the original
conditions were. Please show the extents of the previously existing gravel surfaces on the
plans, as well as the extents of the gravel surfaces in the current condition.
• The resubmitted plans do not accurately depict the existing gravel driveway
dimensions; what is shown resembles the 2016-2017 gravel driveway visible
from aerial photos.
• Please clarify on the plans if the intention is to restore the gravel driveway to
the previous dimensions or to keep it in its current condition. Please note that
the additional gravel on the existing driveway was not approved through a
permit process, and thus will likely trigger stormwater management, in
conjunction with the proposed addition.
• In my previous comments, it was not clearly stated that meeting or exceeding
2,000 sf of new/replaced impervious surfaces triggers stormwater management.
From what is shown in the resubmitted plans, this project proposes 2,000 sf of
new/replaced impervious surfaces. As the plans are currently shown,
stormwater management shall be required. Please revise plans and resubmit
accordingly.
2) The driveway approaches are required to be paved and shall extend from the edge of the
existing street (back of sidewalk) a distance of 20 feet or to the edge of the property line,
whichever is greater (Edmonds City Code 18.80.060C). Please adjust the plans accordingly.
• Please note that the upgrade from the two gravel driveway approaches to the
two (2) 12' by 20' asphalt approaches will count as new impervious surfaces;
please include these new impervious areas in the calculations for the total new
impervious surfaces.
3) Adding gravel beyond the extents of the previously existing driveway limits, as well as
adding pavement to the driveway approaches, will count toward new and replaced
impervious surface areas. If all new and replaced impervious surface areas exceed 2000sf,
stormwater mitigation will be required. Revise the total new and replaced impervious
surfaces on the plans to include the new gravel drive surfaces and paved driveway
approaches.
• Please note that refreshing existing hard -pack drive surfaces with new gravel will not
count toward the total new and replaced impervious surface areas; adding new gravel
outside of existing hard -pack drive surfaces will count toward the total new and
replaced impervious surface areas.
• Please note that meeting or exceeding 2,000 sf of new/replaced impervious
surfaces shall require stormwater management.
