Scope of Project
The project is the construction of an attached garage to an existing single-family residence that is located
in Kala Point on Div. 1, Lot 21 at 93 Saddletree Drive. The subject site is a platted lot for the purpose of
single-family residential construction, and is sized for on-site sewage system. The site has an average
slope differential of less than ten feet from the frontage on Saddletree Drive.
Of note, the existing downspout conveyance system for stormwater includes an existing tight-line from
the west-side downspouts which outflows to an existing 95 foot stormwater swale on the West side of the
property. It is the owner's intent to relocate the existing downspout to be removed for the garage
addition, and re-install same on the exterior corner of the garage and reconnect to the tight-line
conveyance system.
It is the owner's intent and responsibility to provide this plan for stormwater management on the subject
site.
Soils Data
Source of data is the Soil Survey of Jefferson County Area, Washington, U.S. Dept. of Agriculture, Soil
Conservation Service. The principal soil type for the subject site is"Cassolary Sandy Loam" [CfC].
The soil is well drained. The seasonal water table is >5 feet. Permeability is moderately slow at 2 to 6
inches per minute, and holds 7 to 9 inches of water available for plants. Runoff is slow to medium, and
the hazard of water erosion is slight to moderate. Shrink-swell potential is low. Frost action potential
does not normally exist for this soil type.
Project Overview
1. Describe the proposed developed conditions of the site. Indicate position and relative size of
proposed improvements on the site map.
The project is a 265 square foot attached garage addition to an existing single-family residence on a
16,056 square foot residential lot with paved road frontage["Saddletree Drive'J.
The proposed "redevelopment" impervious surface total falls within the "small project" impervious
surface requirements under the Washington State Stormwater Management Manual for Western
Washington.
Existing Conditions Summary
2. Describe the existing topography. Indicate contours on the site map.
The site with essentially gentle sloped landscape leading away from Trafalgar Dx; e property slope
average is less than 10 feet of elevation change from the east to west
Stormwate
Bondurant Stormwater Mgmt Plan.doc 11/4/2009 Required 1
• •
3. Describe the existing vegetation.Indicate native vegetation areas on the site map.
The site is predominately first order growth, with a four Douglas Firs and Alder trees within and around
the subject site. Owner planted vegetative under-story is present.
4. Describe the existing soils.Indicate soil type on the site map.
The predominant soils consist of the Casollary Sandy Loam[CfC]series of nearly level to rolling soil on
terraces.
5. Describe the existing site hydrology (i.e., drainage; behavior of water on the site — above,
below, and on the ground). Indicate existing storm water drainage to and from the site on the site
map. Depict separate drainage basins on the site map,if applicable,and indicate acreage of each.
The soil is well drained. The seasonal water table is >5 feet. Permeability is moderately slow at 2 to 6
inches per minute, and holds 7 to 9 inches of water available for plants. Runoff is slow to medium, and
the hazard of water erosion is slight to moderate.
6. Describe any excess levels of noise generated by the proposed use or activity.
The proposal is for construction of an attached garage to the existing single-family residence and only
the typical accessory uses associated therewith. This property is a large parcel, which inherently
provides larger property setbacks. Excess noise is not a factor as it will be short term during
construction only.
7. Describe significant geographic features and critical areas (i.e., environmentally sensitive
areas such as wetlands,streams,steep slopes,etc.)on the site.Indicate location on the site map.
None have been determined for this site.
8. Describe the general vicinity of the site,including adjacent land uses and structures, utilities,
roads,and sensitive/critical areas(streams,wetlands,lakes,steep slopes,etc.).
Adjacent properties consist of single-family residences nestled in amongst trees and served by paved
roads, with utility services of water, sewer,power, telephone, cable underground. No sensitive or critical
areas have been determined for this immediate area.
Permanent Storm water Control Plan
This portion of the Storm water Site Plan consists of the selection and installation of the appropriate storm
water control BMP's and facilities to remain in place after construction of the project is completed.
"Medium" size projects are required to have the totals calculated of all impervious surfaces, pollution-
generating impervious surfaces, and pollution-generating pervious surfaces to verify that the thresholds
for treatment facilities and flow control facilities are not exceeded. Please see Master Permit Application
submittals for these calculations.
9. Describe the developed site hydrology, as proposed. Indicate whether storm water will be
fully dispersed (i.e.,per BMP 15.30 in the Manual)or,if not,what types of storm water flow control
will be utilized for the site or specific threshold discharge areas within the site. Locate these
facilities on the site plan and differentiate proposed facilities from existing facilities.
The placement of the garage and built-in permanent gutter and downspout will provide channeled roof
flow via the downspout to the existing underground tight-line which leads to an exists 95 foot drainage
Bondurant Stormwater Mgmt Plan 5/3/2009 2
swale along the west side of the property. The existing surface swale is for downspout dispersal of
stormwater by transpo-evaporation, and natural drainage infiltration..
If the proposed project was found to not be eligible for roof stormwater conveyance via downspout
dispersion, the proposed project is eligible for dispersion system using an infiltration drywell. [See item
14. below]. One [1] proposed drywell will serve less than a maximum of 1000 square feet of roof
surface.
From the relocated garage downspout, stormwater would then be conveyed to one [1] drywell
constructed with the performance-based design from Chapter 3 "Flow Control Design"from Vol. III,
Hydrologic Analysis, Flow Control BMP's, Figure3.4 "Typical Downspout Infiltration Drywell", copy
attached.
10. If the project requires the use of storm water treatment facilities, describe the types of storm
water treatment facilities proposed for use on the site. Locate these facilities on the site plan and
differentiate proposed facilities from existing facilities. [This is normally for large" projects or
projects that involve the potential for dispersion of contaminants.]
No storm water treatment is necessary for this project.
11. Describe the performance goals and standards applicable to the project.
All storm water is managed so as to not create erosion or on-site/off-site migration impacts. This is
evidenced by the fact that existing stormwater controls using the land swale method has functioned
properly without any erosion or off-site impacts.
12. Describe the flow control system.
The placement of the garage and relocation of the downspout connected to the existing underground
tight-line, which empties into the existing stormwater swale on the west property line will provide
channeled roof flow to the swale area for transpo-evaporation, and natural infiltration.
If the proposed project was found to not be eligible for roof stormwater conveyance via downspout
dispersion, the proposed project is eligible for dispersion system of infiltration drywell. The placement of
the garage will provide channeled roof flow via downspout to the drywell based upon the performance
based design of Vol. III, Hydrologic Analysis, Flow Control BMP's, Figure3.4 "Typical Downspout
Infiltration Drywell", copy attached.
The drywell bottom would be a minimum of one foot above the seasonal water table, since that table is
greater than five[5]feet.
The drywell is projected to be 36-inches in diameter and have a depth of five feet[four feet of gravel and
1 foot of suitable cover material].
Filter fabric [geo-textile] will be placed on top of the drain rock and on the drywell sides prior to
backfill ing
Conveyance piping from the downspout to the drywell will be the performance-based design from
"Figure 3.4. "BMP.
13. Describe the water quality system.
None is proposed or required of this proposal.
Bondurant Stormwater Mgmt Plan 5/3/2009 3
• •
14. Describe the conveyance system analysis and design.
None is proposed due to the low rainfall statistics of the area, and due also to the size of the property, and
due to the performance of the existing stormwater swale.
The soil type is medium to course sands, which allow for the use of the existing stormwater
swale, and if not allowed, a single drywell would be incorporated using the performance based
design from Vol. III, Hydrologic Analysis, Flow Control BMP's, Figure3.4 "Typical Downspout
Infiltration Drywell", copy attached.
15. Describe the source of fill material; physical characteristics of fill material,and deposition of
excess material.
Garage foundation excavation material will be primarily re-deposited, and back-graded to form a slope
away from the garage.. It is estimated that up to 16 cubic yards will be excavated for the foundation. Fill
material would consist of some of the excavated material for foundation backfill.
16. Proposed methods of placement and compaction consistent with the applicable standards in
the International Residential Code,2006 Edition.
Light machinery use will provide primary spreading and compaction, normally with the use of a bob-cat.
Foundation excavation could involve a backhoe or excavator.
17. Describe the proposed surfacing material.
Yard area around the garage may be seeded with grass and contain traditional landscaping plantings.
18. Describe methods for restoration of the site.
Reforestation is not required, as the site is fully landscaped. No vegetation is required to be removed for
this project as the garage site is currently a crushed-rock parking space. The owner may choose to
increase the number of existing trees with additional planting.
19. An Operation and Maintenance Manual is required for each flow control and treatment
facility. [This is normally required for"large" projects only and only those for which facilities are
required to control flow or treat runoff.]If included,list the Manuals here.
Not applicable for this proposal.
20. List here and include any special reports or studies conducted to prepare the Storm water
Site Plan.
None known for this parcel.
21. List other necessary permits and approvals as required by other regulatory agencies. If those
permits or approvals include conditions that affect the drainage plan or contain more restrictive
drainage-related requirements,describe those conditions or restrictions here.

CONSTRUCTION STORMWATER POLLUTION PREVENTION PLAN(SWPPP)
The Construction SWPPP addresses sediment and erosion control during construction. The BMP's
indicated by the applicant in the template that follows must be installed on the ground during all
construction phases of the project. The proponent is responsible for preventing sediment and erosion
impacts to environmentally sensitive areas and off-site areas. Consult the Construction Storm water
Pollution Prevention(SWPP)Best Management Practices (BMP's)Packet for guidance,particularly with
rural residential development.
SECTION I-CONSTRUCTION SWPPP NARRATIVE
1. Construction Storm water Pollution Plan Elements. Describe how each of the Construction
SWPPP elements has been or will be addressed. Identify the type and location of BMP's used to satisfy
the required element. If an element is not applicable to the proposal,justification is provided.
Required Elements-Construction SWPPP:
1. Mark Clearing Limits.
Minimize limit of land excavation to the garage site only, and marking [flagging] equipment
operation zones if necessary
2. Establish Construction Access.
Via the existing driveway, machinery will not require a formal construction access. Wash-down of
vehicle tires on-site will further control such occurrence during wet days.
3. Control Flow Rates.
BMP C121 "Mulching" may be implemented to filter any and all downhill water flow, and thus
stabilize the flow rate which will be directed to the existing stormwater swale on the west property
line.
4. Install Sediment Controls.
While limiting the area for construction of the garage, the applicant may install a silt fence at the
west side of the proposed garage, to protect " downstream" silt from entering the existing
stormwater swale area during construction per BMP C233.
5. Stabilize Soils.
The applicant proposes to use BMP C121 "Mulching" to stabilize exposed soils that are subject to
erosion, where applicable along the proposed garage..
6. Protect Slopes.
The applicant proposes to use "surface roughening" BMP C130 and soil stabilization with BMP
C121 " Mulching" at sloped area on the west side of the garage during construction, until new
vegetative growth is established, where and when necessary.
7. Protect Drain Inlets.
No culverts or drain inlets exist either on or off the subject site.
Bondurant Stormwater Mgmt Plan 5/3/2009 5
• •
8. Stabilize Channels and Outlets.
No temporary or permanent on-site channels or ditches exist or are to be created to control runoff.
9. Control Pollutants.
No vehicle or machinery maintenance is to be allowed on-site over impervious surfaces, and
contractor's equipment will be required to not exhibit hydraulic oil or fuel leakage prior to storage
or use on the site.
10. Control De-Watering (the act of pumping groundwater or storm water away from an
active construction site).
Since the proposal consists of a foundation on-grade, in the event of any water retention, a small
channel may be created during construction to allow drainage of the foundation excavation which
will likely require the use of BMP C209 and mulching BMP C121 until foundation backfill is
completed.
11. Maintain Best Management Practices(BMP's).
The owner or owner representative is to supervise contractors to insure that BMP's are maintained
to their respective functional design.
12. Manage the Project.
Construction is to be phased to prevent transport of water runoff or sediment, and limiting work
during wet conditions where there may be a negative impact. Coordination of any utility work—i.e.,
same trench use included, coupled with daily inspection and maintenance of system, is proposed.
2. Adjacent Areas.
a. Description of the adjacent areas that may be affected by site disturbance(e.g., streams, lakes,
wetlands,residential areas,roads).
None to be affected.
b. Description of the downstream drainage path leading from the site to the receiving body of
water(minimum distance of 400 yards).
The proposed project will not result in or create off-site/down-stream drainage paths.
3. Environmentally Sensitive Areas.
a. Description of environmentally sensitive areas that are on or adjacent to the site.
None known to applicant.
