RE: BLD20190120 — Hyundai Sales & Service CIT
Plan Revision: Added Pedestal Parking Stall
Dear Zack:
The corporate Hyundai has handed down direction to add a pedestal parking stall along the Hyundai
frontage. I assume this is a stall that will be elevated approximately 6" higher than the adjacent stals
and used to show off a featured vehicle. The plan revision is clouded on sheet C2.00-3 of the
Hyundai Building Permit set. It is attached to an architectural plan revision package.
This addition creates 751 square feet of new plus replaced impervious surface to track in the flow
control, water treatment, and various area swaps we have been tracking throughout the overall
project. The latest drainage report with the most accurate stormwater tables was dated September
20, 2019, submitted for the Mazda Service Center project. The previous Hyundai Sales & Service
drainage report is now obsolete with regards to the stormwater tables.
Therefore, rather than resubmit an entire drainage report for Hyundai, in an attempt to streamline
review, I have attached only the redlined updates required for the relevant stormwater tables and
exhibits. These pages were copied from the Mazda Service Center drainage report dated September
20, 2019. They now apply to Hyundai, as both projects are being mitigated with the same
stormwater facilities.
I hope this is clear but if not don't hesitate to request any additional information.
Thanks,
John C. Farleigh, P.E.

S. PERMANENT STORMWATER CONTROL
5.1: DESIGN OVERVIEW
This project is being constructed in conjunction with the Doug's Lynnwood Mazda project
(BLD201 71119). The project will replace the existing automotive service building with a larger
service building. Parking improvements for the project will be provided by formalizing existing
parking and car inventory storage area. The architectural site plan provides accounting for the
parking requirements. The building will be fully sprinkled.
Stormwater mitigation for the site will comply with the 2016 City of Edmonds Stormwater
Management requirements. The City has adopted the 2014 Stormwater Management Manual for
Western Washington with amendments in chapter 18.30 of the municipal code. Flow control will
be provided in an underground concrete detention vault. Water quality will be provided by an in -
line Linear Modular Wetland Filter installed under a separate permit, the Doug's Lynnwood Mazda
project, permit number BLD201 7119.
5.2: FLOW CONTROL
Flow control is provided via underground concrete detention vault installed under a separate
permit (BLD201 71 1 19), located onsite. The table below shows the new plus replaced impervious
areas required to be mitigated under this project and previously permitted areas that are
mitigated within the same vault. In addition, the table below includes 25% mitigation for existing
un-mitigated hard surfaces, required for minimum requirement #5. The original detention vault
sizing calculations made a reasonable assumption for this development. However, they did not
accurately aEEuFate capture these final conditions. Therefore, sizing verification calculations have been
attached in Appendix B based on the total developed condition.
6,338 sf 875+571 sf = 1,626 sf
Area Swap (#1):
Approximately 5,58sf of runoff from a com Ion of 76`" Avenue W and an onsite gravel
parking area is being collected in lieu o lecting Hwy. 99 sidewalk area. That's 4,712 square
feet from 76`" Avenue W and-8- 5 uare feet from the upper inventory parking area. The areas
swap is being proposed because the Hwy. 99 frontage is downhill of the detention vault and
cannot reasonably drained to the vault via gravity. The area swap provides stormwater mitigation
for a similar sized area that was not previously being mitigated and has no imminent plans for
improvements that would otherwise trigger stormwater mitigation for this area.
Area Swap (#2):
The project is proposing an onsite area swap to mitigate new plus replaced impervious areas
specifically for the concrete pedestrian walkway located on the north end of the project. The
walkway provides a connection from the parking area to the Amenity Shelter. A storm line has
been provided to the shelter to collect roof runoff; however, the walkway is difficult to collect
without excessive storm lines and cutting & patching of the driveway. The project is naturally
collecting runoff from the gravel Inventory Parking Area located on the west -end of the site. The
walkway area is approximately 1,647 sf (see table below).
Area Swap Exhibits have been attached in Section 7 for reference, see Figure 6 & 7.
Collected Area Not Required for Mitigation:
As stated above, the site slopes, generally, from the west to the east. The gravel parking area,
commonly referred to as the "upper inventory parking area," is draining downhill through the site
improvements and will be collected by the new stormwater system and routed through the water
treatment facility and flow control facility. A portion of the gravel parking area is required to get
collected because it is being re -graded (new plus replaced impervious), or it is being mitigated for
MR #5 (25% mitigation of existing hard surfaces), or to support an area swap as described above.
CECIL & ASSOCIATES, LLC Mazda Service Center
7 Edmonds, WA
The areas being collected that are not targeted for flow control mitigation will be routed through
the flow control facility. To account for this, there is a base flow of impervious area assumed in
the existing site condition calculations. To clarify, the predeveloped surface assumption for all
targeted new plus replaced impervious areas is assumed to be forested and existing impervious
surfaces that are routed through the vault not targeted for flow control mitigation are modeled as
existing impervious. This increases the allowable release rates incrementally to offset the
impervious area assumed on the developed condition to allow it to "flow through" the facility.
This is an equivalent downstream result as routing the runoff around the flow control facility, but
it is more practical than installing a dedicated stormwater bypass line through the site. The table
below summarizes how the upper inventory parking area is being counted.

5.3: WATER QUALITY
The project triggers enhanced water quality for all new and replaced pollution -generating hard
surfaces (PGHS). Additionally, the project drains to Lake Ballinger and therefore requires
phosphorus treatment per ECDC 18.30.060.B.i. The water quality treatment will be provided by
routing all runoff from the parking and driving surfaces to a Modular Wetland System (MWS) -
Linear Modular Wetland. The Linear Modular Wetland has received a General Use Level
Designation (GULD) from Ecology for Enhanced water quality and Phosphorus treatment. The
required water quality flow rate has been calculated using 2012 WWHM. The treatment units will
be located upstream of detention, requiring a water quality design flow rate equivalent to the
offline 1 5-minute peak flow rate. The Linear Modular Wetland can be provided in multiple sizes.
The Linear Modular Wetland provided under separate permit, BLD201 71 1 1 9, has an approved
filtration rate of 0.147 cubic feet per second. The table below shows the pollution generating
surfaces areas for this project.

Collected Area Not Required for Mitigation:
There is an additional 6,868 square feet (0.158 acres) of runoff routed through this water
treatment facility than are required. This area is not included in the table above but still is within
allowable size for filtration requirements (58,256 sf + 6,686 sf = 64,942 sf).
5.4: CONVEYANCE REQUIREMENTS
This section discusses the criteria that will be used to analyze and design the proposed storm
conveyance system. For basic conveyance system design, the ECDC requires the use of the latest
edition of the King County Surface Water Design Manual (SWDM), Chapter 4: Conveyance System
Analysis and Design. Chapter 4 refers to Core Requirement #4, which is found in Chapter 1.2.4
of the KCSWDM. The relevant portions of this Section prescribe the following:
