Determination:
Study Required
Determination #:
CRA-2010-0079 --
Applicant Rep:
Cozy Homes Corp.
Owner/Applicant:
Robert Rixmann
BACKGROUND
During review and inspection of the subject site, it was found that the site co-'ntains and/or is
adjacent to critical areas, including Geologically Hazardous Areas, pursuant to Chapters 23.40 and
23.80 of the Edmonds Community Development Code (ECDC).
The subject parcel is fairly level on the southeastern one-third of t . he parcel then slopes down
gradually toward the northwest. According to the City's LIDAR data, the steepness of the slope
varies from approximately 15% to 35% which qualifies the slope as an erosion hazard.
This study applies to the entire subject parcel. Depending on the location and type of project
proposed relative to the identified, critica I areas, certain studies and reports may be required.
ALLOWED ACTIVITIES AND EXEMPT DEVELOPMENT PROPOSALS
Certain activities are allowed in or near critical area buffers as specified in ECDC 23.40.220,
Similarly, certain development proposals may be exempt from Critical Areas Requirements (ECDC
23.40.230). If you have any questions about whether your proposed development qualifies as an
allowed or exempt activity, please contact a Planner for more information.
DEVELOPMENT PROPOSALS ASSOCIATED WITH EROSION HAZARD AREAS
Development within an Erosion Hazard Area must meet certain criteria.
For projects within erosion hazard areas with suitable slope stability, the only
critical area report needed is an erosion and sediment control plan prepared in
compliance with the requir ements set forth in Chapter 18.30 ECDC. This option is at
the director's discretion, per ECDC section 20.80.050.G.
0 In areas where.the slope stability is not suitable, projects within erosion hazard areas will
require a report by a licensed geotechnical engineer.or other qualified professional. Note
that- it is important for the report to be prepared by a qualified professional as defined in the
Edmonds Community Development Code.
0 Report requirements are specified in ECDC 23.80.050, and more generally in ECDC
23.40.090. D.
0 Development standards are identified in ECDC 23.80.060 and 23.80.070.
GENERAL CRITICAL AREAS REPORT REQUIREMENTS
Critical Areas Reports identify, classify, and delineate any areas on or adjacent to the subject
property that may qualify as critical areas. They also assess these areas and identify any potential
impacts resulting from your specific development proposal. If a specific development proposal
results in an alteration to a critical area, the critical areas report must also contain a mitigation
plan.
Please review the minimum report requirements for all types of critical areas that are listed in
ECDC 23.40.090.D. There are additional report requirements for different types of critical areas
(see below).
0 Note that it is important for the report to be prepared by a qualified professional as defined
in the ordinance. There are options on how to complete a critical areas study, and there is
an approved list of consultants that you may choose from. Please contact the Planning
Division for more information.
0 General mitigation requirements for all critical areas are discussed in ECDC 23.40.110
through 23.40.140.
If you have any questions about this determination, please contact a Planner for more information.

Site -Classification Worksheet
The project's Classification serves to identify the specific Stormwater Management requirements applicable
to your site. Complete the worksheet below to determine whether your project falls into the classification of
a Large Site Small Site (Category I or Category 2), or a Minor Site.
�j�: Determine the Exempt Impervious Surface Area for your project and enter it on line I of the
table (yellow box).
Step 2: Determine the Replaced Impervious Surface Area for your project and enter it on line 2 of the table
below dividing the total between Exempt and Non -Exempt (orange and blue boxes); either or both may be zero.
Step 3: Determine the New Impervious Surface Area for your project. If a portion of the new impervious surface
area is also Non -Exempt Replaced Impervious Surface Area subtract this from the total of the new impervious
surface area. Enter the final value on line 3 of the table below (blue box).
Step 4: Add the values in the Non-exempt column for lin�s 2 and 3 and enter it into line 4 (green box).

Kernen Lien, Associate Planner J-��
BLD20100906 and Lot Combination Issues
Robert and Leah Rixmann have applied to construct a new single family residence on the
property located at 7017 174 th Street SW. According to the site plans submitted with the
application, the proposed residence would straddle the parcel line between 00513100013805 and
00513100014320 and thus would not meet the proscribed zoning setbacks for the RS-20 zone.
The legal descriptions for the two parcels are:

As noted in the legal descriptions, the two parcels are portions of a single parcel (Parcel 1)
created under the City of Edmonds short plat number S-21-81 recorded under auditor file number
8303100246 (Attachment 1). The City of Edmonds asked the Rixmann's to dissolve the parcel
line between parcels 00513100013805 and 00513100014320 based on the fact that parcels are
0
0
intended to be a single property according the approved City of Edmonds short plat. The
Rixmann's complied with the City's request and requested the Snohomish County Assessor's
Segregation Department to dissolve the parcel line between parcels (Attachment 2).
Following the request for lot combination with Snohomish County, Jennifer Hansen of the
County's Segregation Department contacted the Rixmann's and informed them the parcels could
not be combined because the County records indicate the property is located in two separate
taxing districts. Ms. Hansen provided the City of Edmonds with the map included as
Attachment 3 showing a small area in the center not located in the Alderwood Water and Sewer
District which the map indicates extends through the rest of the property in the vicinity of the
subject property.
I contacted Alderwood Water and Sewer Districts who indicated this area is not within their
service area. The map included as Attachment 4 shows the Rixmann's property to be located
well outside of Alderwood's service area. This information has been provided to Snohomish
County who, along with the City, is continuing to pursue the taxing district boundary issues.
The proposed residence at 7017 174 th St SW would meet the proscribed zoning setbacks if the
parcel line between parcels 00513100013805 and 00513100014320 were dissolved. Given that
the two parcels are intended to be a single buildable lot according to the City of Edmonds short
plat number S-21-8 1, Planning will sign off of the proposed Rixmann residence while the City of
Edmonds continues to pursue the taxing district issue with Snohomish County.

Dear Mr. Rixmann: BUILDING DEPARt—WENT
CITY OF EDMONDS
In accordance with your request, Earth Solutions NW, LLC (ESNW), has visited the subject
property and reviewed the referenced plan sheets. Construction of a new single family
residence is proposed for the subject property. The new residence will occupy the approximate
footprint area of the existing residence. Stormwater control will be accomplished through a
series of infiltration and dispersion trench systems. A rain garden -will be constructed within a

percen
slope (or flatter) are located within the northerly portions of the site The planned dispersi , o' n
system down gradient of the rain garden will, be located in an area where slope gradients are
less than 40 percent. Vegetative flow paths will be preserved down gradient of the dispersion
systems. As part, of the rain garden construction, a small retaining wall (five feet or less) will be
constructed.
Geotechnical Evaluation
Based on our observations and review of the referenced plans, the planned development and.
stormwater control systems are feasible from a geotechnical standpoint. Based on review of
the geologic map of the Edmonds Quadrangle (Minard 1983) glacial till'-(Qvt) and advance sand
(Qva) deposits are identified throughout the site and surrounding areas. Based on observation
of a series of hand excavations at the. site, soils are generally consistent with the geologic map
designations.

Section 2: Existing Site Conditions:
The site is a rectangular -shaped, 21,780 square -foot single family lot that is occupied by an
existing 2,100 sf house (built in 1940) and adjacent shed. The southerly portion of the site is
relatively flat, and the northerly portion contains slopes which generally drain toward the
northwest. Since there is no adjacent storm drain system, the natural discharge area is by
sheetflow across vegetation to the northwest comer of the site. The site has direct access from
174 1h Street SW. The site sewer will be the existing side sewer that connects to the sewer main
in Meadowdale Beach Road to the north. Water will be provided by the existing meter that
connects to the existing 6" water main in 174 1h Street SW.
Section 3: Proposed Project:
The applicant proposes to demolish the existing house and driveway and. obtain City permits to
construct a new single-family residence, and related improvements.
Section 4: Upstream Analysis
There is no significant upstream surface runoff onto the site, since the site is in the upper portion
of the Stilthouse Creek watershed.
Section 5: Downstream Analysis
There are no known onsite or adjacent downstream storm facilities. Currently runoff sheetflows
to the northeast site comer, and appears to run northerly toward Meadowdale Beach Road. The
proposed design was intended to match this drainage pattern and method.
Section 6: Drainage Methodology and Applicable Code
The site has been classified as a Category I small site per Figure 2-1 in this report appendix,
because it does not create or add 5,000 sf or more of new/new+replace/replaced impervious
surface; or it doesn't convert 1/4-acre or more of native vegetation to lawn; or it does not cause an
increase of 0. 1 cfs in the I 00-year flow frequency (based on the enclosed WWHM3 computer
run, the developed site increases the runoff by 0.075-cfs).
The site proposes to use LID techniques as feasible per Chapter 3 of the City Stormwater Code.
In addition, Category I small sites are, subject to the applicable Minimum Requirements (MRs)
of Chapter 5 of the City Storm Code. The proposed project complies with the MRs- as follows:
MR# I -Stormwater site plan — a stormwater plan has been prepared in compliance with Code
Section 5.1
MR#2-Construction Stormwater Pollution Prevention Plan — since less than an acre will be
disturbed, a Temporary Erosion and Sediment Control Plan has been prepared. -
MRO-Source Control of Pollutants — not required for single-family projects
Drainage Report Rixmann Residence
Lovell-Sauerland and Associates BLD# 2010-0906
LSA#5290 February, 2011
MR#4-Preservation *of Natural Drainage Systems and Outfalls — the proposed design intends to
maintain the existing drainage system and location.
MR#5-Onsite Stormwater Management Plan — a plan has been prepared which incorporates LID
techniques as feasible, including a rain garden and downspout infiltration, and flow dispersion
per Table 5-2 of the Storm Code.
MR#7-flow control — by proposing onsite LID/BMPs, per the storm code Section 5.5, the
requirements for MRO have been met. (see enclosed Table 5-3). The rain garden was sized
based on the City's sizing &ctors as follows:
Type: bioretention cell
Ponding depth: 12-inch
Infiltration rate: 0.25 in/hr (see enclosed Earth Solutions NW report)
Sizing Factor: 6.2%
Bottom area required = 3909sf x 6.2% = 243 sf (required); 250 sf (provided on plan)
MR#8-wetland protection: not applicable; no wetlands on the site.
MRO-Operation & Maintenance: Storm Code Table 5-5 has been included in this report for
O&M guidance.
MR# I I -Financial Liability — if the City determines that this is required, the owner shall comply.

Bioreten.tion cells (also known as rain gardens).
Small-scale "traditional" infiltration techniques (such as trenches, dry wells, and
gravelless chambers),
e Permeable pavement (asphalt, concrete, paving blocks,- "grass-crete").
Dispersion BMPs such as wheel strip driveways or other pavement sloped to drain to
drain to onsite vegetation adequate for dispersion, or downspout or sheet flow
dispersion.
Onsite/LID BMP design requirements shall be those in the LID Manual or the Washington Statd
Department of Transportation's Highway Runoff Manual. BMP design requirements presented in other
storrnwater management manuals or standard documents approved by Ecology such as the City of Seattle
and King County stormwater manualsare also acceptable when modified for local conditions such as
precipitation and soil conditions. Table 5-2 presents a summary of Onsite/LID measures that could be
used 1to manage stormwater onsite, along with references for design guidance information. Additional LID
BMPs can be proposed as long as they are found in an Ecolog y-approved stormwater manual, appropriate
for site conditions, and do not cause flooding or erosion impacts onsite or offsite.
LID.Jechniques that rely on infiltration should be designed with caution, due to the prevalence of till or
"hardpan" soil and steep slopes in Edmonds. Section 5.5.2 discusses this matter further.

2.3.2 Runoff Parameters
All storm event hydrograph methods require input of parameters that
describe physical drainage basin characteristics. These parameters provide,
the b ' asis ftom. which the runoff hydrograph is developed. This section
describes only the key parameter of curve number that is used to estimate the
runoff from the water quality design storm. .
Curve Number The NRCS (formerly SCS) has, for many years, conducted studies of the
runoff characteristics for various land types. After gathering and
analyzing extensive data, NRCS has developed relationships between land
use, soil type, vegetation cover, interception, infiltration, surface storage,
and runoff. The relationships have been characterized by a single runoff
coelFicien.t called a "curve number." The National Engi . neering Handbook
- Section 4: Hydrology (NEH-4, SCS, August 1972) contains a detailed
description of the development and use of the curve. number method.
NRCS has developed "curve number" (CN) values based on soil type and
land use. They can be found in "Urban Hydrology for Small Watersheds",
Technical Release 55 (TR-55)5 June 1986, published by the NRCS. The
combination of these two factors is called the "soil -cover complex." The
soil -cover complexes have been assigned to one of four hydrologic soil
groups, according to their runoff characteristics. NRCS has classified over
4,000 soil types into these four soil groups. Table 2.2 shows the
hydro: logic soil group of most soils in the state of Washington and
provides a brief description of the four groups. For details on other soil
types � refer to the NRCS publication mentioned above (TR-55, 1986).

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the soils
or miscellaneous areas in the survey area. The map unit descriptions, along with the
maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. VVithin a taxonomic
class there are precisely defined limits for the properties of the soils. On the landscape,
however, the soils are natural phenomena, and they have the characteristic variability
of all natural phenomena. Thus, the range of some observed properties may extend
beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic
class rarely, if eve�., can be mapped without including areas of ot . her taxonomic
classes. Consequently, every map unit is made up of the soils or miscellaneous areas
for which it is named and some minor components that belong to taxonomic classes
other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They generally
are in small areas and could not be mapped separately because of the scale used.
Some small areas of strongly contrasting soils or miscellaneous areas are identified
by a special symbol on the maps. If included in the database for a given area, the
contrasting minor components are identified in the map unit descriptions along with
some characteristics of each. A few areas of minor components may not have been
observed, and consequently they are not mentioned in the descriptions, especially
where the pattern Was so complex that it was impractical to make enough observations
to identify all the soils and miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the usefulness
or accuracy of the data. The objective of mapping is not to delineate pure taxonomic
classes but rather to separate the landscape into landforms or landform segments that
have similar use arid management requirements. The delineation of such segments
I

Custom Soil Resource Report
on the map provides sufficient Information for the development of resource plans. If
intensive use of small areas is planned, however, onsite investigation is needed to
define and locate the soils and miscellaneous areas.
An identifying symbol precedes the map unit name in the map unit descriptions. Each
description includes general facts about. the unit and gives important soil properties
and qualities.
Soils that have profiles that are almost. alike make up a sod series. Except for
differences in texture of the surface layer, all the soils of a series have major horizons
that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,
degree of eroslonj and other characteristics that affect their use. On the basis of such
differences, a soil. series is divided into soil phases. Most of the areas shown on the
detailed soil maps are phases of soil series. The name of a soil phase commonly
indicates a feature that affects use or management. For example, Alpha silt loam, 0
to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps. The
pattern and proportion of the soils or. miscellaneous areas are somewhat similar in all
areas. Alpha -beta complex, 0 to 6 percent slopes, Is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present or
anticipated uses of the map units in the survey area, it was not considered practical
or necessary to map the soils or miscellaneous areas separately. The pattern and
relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -
Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas that
could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion of
the soils or miscellaneous areas in a mapped area are not uniform. An area can be
made up of only one of the major soils or miscellaneous areas, or it can be made up
of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil material
and support little or no vegetation. Rock outcrop Is an example.

In accordance with your reqUeSt, Earth Solutions NW (ES.NW) has priapared this report and
e.valuatlon Of infiltration characteristics of the soils along the,align . en . t of the proposed
m
infiltration trench system, As part of our evaluation, Chapter 6' of the. City of Edmonds
Stormwater Supplement. (section 5.5,2 and Appendix C) were reviewed. Four test pits were
excavated along the alighm'erif of the proposed infiltration trench system, The National
Resoun;,es Conservation Service identifies Alderwood-Everett gr6
velly sandy loam Soils (25 to
75 percent slopes) throughout-thp �Area of the planned i0filtration1rench con�struction, Although
the National Resources Conservation Services identifies 25 to 75 Percent slopes., the area of
the infiltratiort system Is rel.qtIvely flat, Based on our observations, it, is, likely the existing yard
area�wh!.ere the.system is proposed is located in a cLit that was excavat I ed., . a s-part. of the originW
development,
Infiltration Evaluation
Based on the subsurface exploration and USDA textural analysis, . soils along the alignment of
the planned infiltration system are comprised largely of sandy loam, Appendix C of the City of
Edmonds Stormwater Supplement specifies long-term infiltration rates for USDA classified
soils. Given a correction factor of 4.0, the long-term infiltration rate for sandy loam is 0.25
inches per hour. Therefore, the following long-term design infiltration rate should be used for
the infiltration system:
* Long-term infiltration rate
0.25 inches per hour

A site plan illustrating the approximate location of the test pits is attached. � Soil logs and the
USDA textural analysis data sheet are also aftached. -
Permeable Patio Pavers
With respect to the proposed Patio and pervious pavers, the specified long-term infiltration rate
for the infiltration system can be assumed. The test pits excavated for the infiltration system
are in relative close proximity to the planned patio. Therefore, a long-term infiltration rate of
0.25 inches per hour should be used for the patio pavers.
We trust this geotechnical evaluation meets your current needs. If you have any questions, or if
additional information is required, please call.
Sincerely,
