Introduction
This report has been prepared at the request of Brian and Nancy Duffy in support of a single family
residential building permit for a site located on the east side of 74't' Ave W. Edmonds, Washington
in the NE'/a of the SE'/a Section 32, Township 27 North, Range 04 East W.M. The site address is
755 Daley Street, Edmonds WA. (Parcel #27043200200100) (Referto Site Location and Vicinity
Map).
This report addresses the drainage report contents and organization of MR 1 to MR 9 per DOE 2014
Stormwater Management Manual as adopted by the City of Edmonds. Specifically we have designed the
drainage using a review of the LID applications as outlined in Volume 1, Chapter 2, Table 2.5.1 of the
DOE 2014 Stormwater Management Manual.
Section 1: Project Overview
The project consists of the construction of a new home on a 6,593 sf site. The existing lot contains a
house and garage which will be removed to build the new home. The existing patios, decks and driveway
will remain. The site cover is trees and lawn.
Once developed, the site will add a new home with a total of 2,220 sf of new impervious area in the form
of roof for the home, and concrete pads. The existing patios, decks and driveway will remain.
The area of disturbance is 4,300 s£

Section 2:
Existing Site Conditions
The project consists of construction of a new home on a 6,593 sf site. The existing lot contains a house
and garage which will be removed to build the new home. The site cover is landscaping and lawn. The
site has slopes around 4 to 10 percent with runoff flowing to the south onto Daley Street.

Bailey SFD Revised: September 14, 2022 Page 4
Section: 3
Offsite Analysis Report
Per Section 2.5, Stormwater site plans and SWPP Plans have been prepared for the site and are included
with this storm drainage report. BMP's are proposed for the site since the runoff from the roof
impervious area is under 5,000 sf.
OFF SITE ANALYSIS AND MITIGATION
An Off Site Analysis and Mitigation Study meeting requirements outlined in Section 2.5.1 was
performed on November 21, 2021. The weather was partly cloudy and cool at the time of the field
inspection. See Downstream Analysis Map.
TASK I. PROJECT OVERVIEW & STUDYAREA DEFINITION
Existing Site Conditions: The existing lot contains a house and garage. The site cover is trees and lawn
with slopes around 4 to 10 percent. The site itself drains towards to the south.
TASK 2: REVIEW OF AVAILABLE INFORMATION ON STUDY AREA
Resource Review:
The following is a description of the resources that were reviewed for the preparation of this Level 1
Drainage Study:
A. Basin Recognizance Summary: Enclosed within are downstream and upstream basin area
map which clearly define the flow pass and the drainage basins related to this project.
See (Downstream Analysis Map)

Bailey SFD Revised: September 14, 2022 Page 5
the stream as determined by the FEMA maps.
D. Other Off -Site Analysis Issues: None Noted
TASK 3 & 4: FIELD INSPECTION AND DESCRIPTION OF DRAINAGE SYSTEM WITH
EXISTING AND PREDICTED PROBLEMS
A Level 1 drainage analysis and "Off Site Analysis and Mitigation Study" meeting requirements
outlined in Section 3.2.0 was performed. See Downstream Analysis Map.
Level 1 Downstream Drainage Analysis:
Section 1: Upstream Drainage Analysis:
Based on the site contours there is little if any off -site runoff draining onto the site and therefore
the drainage is limited to the site itself.
A review of the upstream area indicated that there were no indications of problems observed.
Section 2: On -site Drainage Considerations:
All runoff from the site drains to the south and into the storm drainage system serving Dailey Street
Section 3: Site to Daley Street to Casper Street to Hindley Lane to Puget Sound
The runoff from the site leaves the lot along the south property line where it is intercepted by the
storm pipe and catch basin system on Daley Street. From here the storm pipe system runs east for
150-feet before turning north where it runs along the east side of Holy Rosery School for 2,200
feet crossing Casper Street and up to Hindley Lane where it turns north on 8th Ave N to Melody
Land where it then flows west. This storm system then turns north, then west where discharges
into Puget Sound. The total piping distance is 4,500 feet.
There appeared to be no issues with the downstream drainage system. However, parts of the
downstream course was on private property and not accessible to inspection.
TASK 5: LEVEL 1 MITIGATION OF EXISTING PROBLEMS
In order to mitigate the site improvements, the project proposes the following BMP.
Site is located in a in a direct discharge area. Therefore, no detention is required and the
drainage can tie directly into the street's storm system.
Water Quality Requirements:
With less than 5,000 sf of PGIS area, water quality is not proposed for the site improvements.

Stormwater Control Plan
As discussed above, once developed the site will contain a new home only. The total impervious area
including the home is under 5, 000 sf in size
Under the On -Site Stormwater Management Requirements" the "Low Impact Development
Performance Standards" specifically List 2 of the DOE 2014 Stormwater Management Manual,
Volume 1, Chapter 2, Table 2.5.1, and BMP T5.13 requires that each item must be review and analyzed
for use. The BMP's listed below were reviewed using City of Edmonds "Appendix A: On -Site
Stormwater Management BMP Infeasibility Criteria" as follows:
TABLE 2.5.1 LIST #2 BMP FEASIBILITY
Lawn and landscaped areas:
1. Post -Construction Soil Quality and Depth in accordance with BMP T5.13 in Volume V, Chapter
5 of this manual (Will be used)
Roofs:
1. Full Dispersion in accordance with BMP T5.30 is not feasible because a 65 to 10
ratio of forested or native vegetation area to impervious area cannot be achieved.
Downspout Full Infiltration Systems in accordance with BMP T5.10A is
infeasible since the site soils consist of densely compacted fill material.
2. Rain Gardens in accordance with BMP T5.14A and Bioretention in accordance with
Chapter 7 are not required under ECDC 181.30.060.D.5.iv
3. Downspout Dispersion Systems in the form of dispersion trenches in accordance
with BMP T5.1 OB are not feasible since the site cannot meet the required 50-ft flow
paths.
4. Perforated Stub -out Connections per BMP T5.10 is not feasible since the site soils
consist of densely compacted fill material.
Other Hard Surfaces:
1. Full Dispersion in accordance with BMP T5.30 in Volume V, Chapter 5 of this manual. The site
cannot meet the 100-ft flow paths for the site
2. Permeable pavement in accordance with BMP T5.15 in Chapter 5 of Volume V, is not
required under ECDC 181.30.060.D.5.iv
3. Bioretention in accordance with Chapter 7 is not required under ECDC 181.30.060.D.5.iv
4. Sheet Flow dispersion per BMP T5.12 or Concentrated Flow Dispersion per BMP
T5.11. is not feasible since the site cannot meet the 25-ft require flow path.
Water quality: Since there is no new PGHS areas water quality is not required.
BMP T5.13 "Post Construction Soil Quality and Depth"
The top soils will be stockpile on -site and reused per "Implementation Options #3 per BMP T5.13 "Post
Construction Soil Quality and Depth" which requires "Stockpile existing top soils during grading and
replace it prior to planting... " (See work sheets "List of Figures")

Section 6:
SWPP Plan Narrative
The topography of the site containing the proposed site improvements has moderate slopes. The
soils have identified as a type C . With minimal disturbance and standard erosion control measures
such as silt fence, straw mulching and hydro -seeding, the risk of erosion can be minimized.
The limits of clearing will be restricted to the building site and lot. Greater source control
measures would have to be taken during winter construction such as mulching or plastic sheeting.
Good construction practices will prevent any sediment from leaving the site.
The following are BMP measures to limit adverse impact upon the off -site drainage system:
• Filter fabric fences, as required
• Limited clearing area
• Rock construction entrance pad
• Seeding/ landscaping of any bare areas
• Limited months of construction
• On -Site Fueling (N/A No re -fueling will take place on -site)
• Concrete Wash -out (per BMP C-151)
Bailey SFD Revised: September 14, 2022 Page 13
THE 13 ELEMENTS OF A CONSTRUCTION SWPPP
1. Preserve Vegetation/Mark Clearing Limits: The clearing limits are indicated on the plan sheet. Furthermore,
clearing and grading will be limited to only areas that need to be disturbed for grading/construction of the road
surface to preserve as much natural vegetation as possible. Field marking the clearing limits shall be completed
prior to clearing and grubbing activities.
BMP's: Preserve Natural Vegetation (VEG)
Field Marking Clearing Limits (CL)
2. Establish Construction Access: Access to the construction site shall be limited to the rock construction
entrance. The construction entrance shall be extended to provide access to the construction vehicle/equipment
staging and employee parking areas.
BMP's: Stabilized Construction Entrance (CE)
3. Control of Flow Rates: Storm water detention: No detention is proposed for the site since the increase in
volume is less minimal
4. Installation of Sediment Controls: Sediment control will be provided through a combination of filtration
through the surround on -site vegetation, filter fence, straw bails,
BMP's: Silt Fence (FF) If required
5. Soils Stabilization: Temporary and permanent soil stabilization will be provided. Temporary stabilization will
be provided through the application of straw and/or plastic sheeting to exposed, worked earth. From October 1
until April 30, no exposed soil may remain exposed and unworked for more than two days; after May 1, no
exposed soil may remain exposed and unworked for more than seven days.
BMP's: Plastic Sheeting,
6. Slope Protection: Slopes shall be protected from erosion through cover and prevention of concentrated surface
runoff flows.
BMP's: Plastic Sheeting,
7. Protection of Permanent Drain Inlets: Inlet protection will pe provided for all catch basins.
BMP's: inlet protection will be provided on and downstream of site.
8. Stabilization of Channels and Outlets: All channel slopes shall be constructed and protected against erosion
in accordance with City E.D.D.S.
BMP's: None required
9. Pollutant Control: Pollutants shall be controlled as described in the Potential Pollutants section of this
SWPPP.
10. Dewatering Control: De -watering: Interception of the water table is not expected to occur, even if there is an
increase in precipitation. However, should ground water flows be encountered, the flows can be directed to on
site native vegetation for cleanup.
BMP's: Native vegetation (As Required)
11. BMP Maintenance: All BMP's and SWPPP elements shall be inspected daily and maintained as required.
12. Project Management: The project shall be managed in a cooperative effort by the project manager, contractor,
engineer, and the City inspector. During the construction process, if unforeseen issues arise that cannot be
resolved on site, construction activity (other than SWPPP maintenance) shall be halted and the City inspector
and the project engineer are to be contacted and informed of the situation.
13. Protect On -Site Stormwater Management BMPs For Runoff From Roofs And Other Hard Surface
On -site stormwater management BMPs used for runoff from roofs and other hard surfaces include: full
dispersion, roof downspout full infiltration or dispersion systems, perforated stubout connections, rain gardens,
bioretention systems, permeable pavement, sheetflow dispersion, and concentrated flow dispersion. The areas
on the site to be used for these BMPs shall be protected from siltation and compaction during construction by
sequencing the construction in a fashion to install these BMPs at the latter part of the construction grading
operations, by excluding equipment from the BMPS and the associated areas, and by using the erosion and
sedimentation control BMPs. BMP C 102: Buffer Zone

Since the project is for residential lots, the project does not fall under the "High Use Sites" covering commercial or
industrial sites.
BMP C-151: Concrete Handling (Design and Installation Specifications)
Concrete truck chutes, pumps, and internals shall be washed out only into formed areas awaiting installation of
concrete or asphalt. Unused concrete remaining in the truck and pump shall be returned to the originating batch
plant for recycling.
Hand tools including, but not limited to, screeds, shovels, rakes, floats, and trowels shall be washed off only
into formed areas awaiting installation of concrete or asphalt.
Equipment that cannot be easily moved, such as concrete pavers, shall only be washed in areas that do not
directly drain to natural or constructed stormwater conveyances.
Washdown from areas such as concrete aggregate driveways shall not drain directly to natural or constructed
stormwater conveyances.
When no formed areas are available, washwater and leftover product shall be contained in a lined container.
Contained concrete shall be disposed of in a manner that does not violate groundwater or surface water quality
standards
Maintenance Standards
Containers shall be checked for holes in the liner daily during concrete pours and repaired the same day
