Stormwater Site Plan Report
A. PROßCT OVERVIEW:
This report provides engineering information for the proposed construction of a 10-lot single family
residence plat on a 1.99 ac parcel; the project is located on the west side of 98th Ave SW (north of 2L6th St
SW) in the City of Edmonds. The applicant, Select Homes proposes to remove the existing residences (three)
and all existing hard surface to construct the 10-lot plat on the project site. This report provides the
evaluation for the new ten single family residential development.
Summøry ol Minímum Reguírements lor Category 7 Project:
Minimum Requirement#7- Prepøration of StormwaterSite Plan. 'lhe proposed site development consists
of disturbing about 2.0 acres of land and creating/replacing about 49,400 sf of hard surface area. Thus, the
project is classified as a Cotegory 2 project per the City's classification system. Per ECDC 18.30, Cotegory 2
projects must comply with Minimum Requirements No. 1 through No. 9. The civil site development plans
and this report have been prepared to address the projects impacts.
MinÍmum RequÍrement #2 - Construct¡on Stormwøter Pollutîon Prevention (SWPPP). A construction
Stormwater Pollution Prevention Plan (SWPPP) has be incorporated into the site development plans. A
summary of the site's erosion control measures that evaluates the typical 13 elements of a SWPPP are
included in section E. The total site disturbance area of the project is greater than one acre, thus a formal
Notice of lntent application for NPDES coverage will be made to the Department of Ecology.
MînÍmum Requirement #3 - Source Control of Pollution. Specific source controls are not required for single
family residential sites. General requirements for these sites include preventing the discharge of pollutants
to the City's storm drainage system per Edmonds City Code Chapter 7.200 (lllicit Discharges). This includes
common household items such as pesticides, herbicides, fertilizers, detergents and fluids from vehicle
maintenance.
Single family residences shall incorporate DOE's S411 BMPs for landscape and lawn vegetation
management. Lawn and vegetation management can include control of objectionable weeds, insects, mold,
bacteria, and other pests with pesticides. Examples include weed control on golf course lawns, access roads,
and utility corridors and during landscaping; sap stain and insect control on lumber and logs; rooftop moss
removal; killing nuisance rodents; fungicide application to patio decks, and residential lawn/plant care. lt is
possible to release toxic pesticides such as pentachlorophenol, carbamates, and organometallics to the
environment by leaching and dripping from treated parts, container leaks, product misuse, and outside
storage of pesticide contaminated materials and equipment. Poor management of the vegetation and poor
application of pesticides or fertilizers can cause appreciable stormwater contamination.
MÍnÍmum Requirement #4 - Preseruotion of Noturol Drainage Systems ond Outfolls. The site generally
slopes in a northerly direction towards private properties; there are no concentrated flows or existing
defined conveyance systems located onsite; any site runoff leaves the site as sheet-flow. Stormwater runoff

leaving the site would eventually collect in the existing stormwater systems (pipe/catch basins) along the
south side of 2!4th Pl SW north of the site. The 214th stormwater system routes runoff westerly under 98th
Ave W and then southwesterly to the north side of 215th St SW (near the project site's northwest corner).
The proposed development will reroute the stormwater discharge to the existing stormwater system within
98th Ave W that routes the water to the system along the north side of 215th St SW merging with the system
fram 2L4¡h Pl SW. The merg of the stormwater systems is about 550 ft from the site and thus are considered
to be within the same threshold discharge basin (within % mile, thus no diversion). The project will maintain
the existing downstream basin with only a minor sub-basin re-rout of stormwater flows. The site is located
within the upper reach of the Shell Creek watershed basin per the City of Edmonds maps (see section C).
Minimum Requirement #5 - Onsíte Stormwoter Management. An updated site specific geotechnical
evaluation of the site's soils demonstrates that infiltration is a not a viable option for stormwater
management onsite due to relatively shallow depth to unweathered glacial till soils. Additionally, adequate
flow length paths will most likely not be available for the individual building lots for any dispersion type
BMP. Thus, only perforated stub-out connections and post construction soil amendment are proposed for
onsite stormwater BMP. See civil site development plans and Section C for additional stormwater BMP
evaluation and construction details.
5,6 Minímum RequÍrement #6 - Runoff Treatment. The project proposes to create/replace more than
5,000 sf of pollution-generation hard surface onsite. The project will create about L6,300 sf (L0,000 sf onsite
driveways + 6,300 sf of ROW road redevelopment) pollution generation hard surfaces. Thus, placement of
general use approved basic water quality treatment stormwater filters are included the proposed site
development. Design of the stormwater treatment filters are described in Section C below.
5.7 Minimum Requirement #7 - Flow Control. An onsite stormwater detention vault system will provide
flow control of the site's stormwater runoff. The detention vault system has been designed to meet the
flow control standards of a Category 2 project in a creek or lake basin (restrict the stormwater discharge
duration for half the 2-year to 50-year storm events using a continuous storm event model). The detention
vault has been sized using WWHM software; a full overview of the project's stormwater flow control
measures are provided in section C below.
5.8 Minimum Requirement #8 - Wetland Protection. No wetlands are known to exist on or adjacent to the
site.
5.9 MinÍmum Requírement #9 - Operatíon dnd Moîntenance. An operation and maintenance summary is
provided in section F.

B. EXISTíNG CONDIT'ONS SUMMARY
Exîsting Conditions. The total site consists of about 86,657 sf (1.99 acres) and is currently occupied by
three existing single-family residences with access driveways off 98th Ave SW. The existing houses are
surrounded by grass lawn and landscape areas with several large mature trees throughout the site. The
site is surrounded by single family residences to the north, east and south; 98th Ave SW to the west; and a
stub public road of 215th St SW to the east boundary of the site (see aerial photo below).
The site is generally slopes in the northerly direction in a range between 2% and 10%. No define drainage
courses are found on-site and stormwater runoff would sheet flow northerly direction. No stream or
wetlands were discovered on or immediately adjacent to the site. Additional discussion of the local
drainage basin and downstream path is discussed in Section C of this report.
Soils: ln accordance with the project's site specific geotechnical engineering study by Earth Solutions NW,
LLC the on-site soils consist of silty sand with gravel (USCS: SM) glacial till deposits. The subject site is
underlain by glacial till deposits (Qvt, Vashon till soils). Full soils description is included in the project's site
specific geotechnical engineering study by Earth Solutions NW, LLC.

C. DEVELOPED SITE HYDROLOTY:
Developed Conditions. The proposed project includes the construction of ten single-family residences
and associated frontage improvements, driveways and utilities. All existing structures and hard surface
onsite will be removed/replaced with the site development; landscaping and grass lawn around the new
residence will stabilize the site upon building construction.
The project proposes to create and/or replace 57,20O sf of hard surface with the complete site
development, all existing onsite hard surface will be removed with the project site development. The
following is a summary of the proposed new/replaced hard surface areas:
Total Hard Surface New/Replaced Propo,¡ed = 51,200 sf (L.1.75 ac)
Building Rooftop = 30,000 sf fi löts @ 3,000 sf ea.)
Uncovered Patio and Walk = 2,000 sf (10 lots @ 200 sf ea.)
lndividual Driveways = 8,000 sf (L0 lots @ 800 sf ea.)
Additional Panhandle Driveways = 2,000 sf
Vault Access Road = 1,800 sf
ROW Frontage and Cul-de-sac = 6,300 sf
ROW Sidewalk = 1,L00 sf
Upstream 98th Ave SW ROW Net Run-on Area = 2,220 sf (0.051 ac)
Total lmpervious Surface (Site + Upstream) = 53,42O sf (7.226 ac)
Total Pervious Surface (Lawn) = 37,757 sf (0.867 ac)
An underground detention vault will be installed along the back (easterly) portion of lots 3 and 4 near the
center of the site. The detention vault system will provide flow control of the project's stormwater runoff
(Minimum Requirement #7). The hydrologic analysis uses WWHM2012 software to model historical storm
events in the existing and proposed developed conditions. Per the City of Edmonds (DOE 2014) drainage
manual, the project shall meet the site discharge duration for half the 2-year to 50-year storm events
using a continuous storm event model (WWHM).
The detention vault system will discharge to an Oldcastle Perk Filter'" located downstream of the control
structure; the stormwater filter system will provide basic water quality treatment. The stormwater flows
from the filter system will flow to a receivíng catch basin on-site; the receiving catch basin will gravity
discharge to the public stormwater system along the east side of 98th Ave SW.
Due to the relatively shallow depth of the adjacent stormwater system in 98th Ave SW the stormwater
vault will utilize pumps to discharge the collected stormwater flows. All of the stormwater pumps and
pressurized line system shall be located on private property and covered by drainage easements (no
portion of the pump facilities will be located within public right-of-way). Additionally, a gravity overflow
system will be provided between the detention vault and the gravity basin to accommodate the full
undetained 100-year peak flows (0.7595 cfs) to prevent flooding of the system in the event of pump
system failure.

Net Upstream Collection Area Summary:
Due to placement of existing and proposed stormwater catch basins along 98th Ave SW additional existing
roadway (hard surface) from 98th Ave SW will flow into the project's stormwater system and some minor
areas of by-pass will be created. The below evaluation summarizes the net upstream area tributary to the
project's stormwater collection and detention system. The net upstream area has been included and
accounied for in the beiow stormwater rnodeling calcuiations.

Offsite Analysis. The site is located within the City of Edmonds Shell Creek watershed basin. The Shell Creek
basin is a centralized urban basin that collects stormwater runoff from primarily residential areas in the City
Edmonds and ultimately discharges flows northwesterly to Puget Sound (see attached watershed map).
Site runoff leaves the site as sheet-flow runoff that flows in a northerly direction. Runoff leaving the site
sheet-flows across the neighboring properties and entei'the i'oadside ditch and ci¡lvert system along the
south side of 2!4th Pl SW. The storm system along 214th Pl SW directs stormwater west towards 98th Ave W
(10th Ave S); at the intersection of 2!4rh Pl SW and 98th Ave W flows enter a pipe system (L2") that directs
the stormwater north under 2L4th Pl SW and then west under 98th Ave W. The stormwater system continues
in a southwesterly direction to 2LSth St SW and flows westerly along private properties eventually reaching
Pine St (north side). The system continues westerly along the north side of Pine St to 9th Ave S; the
stormwater system is then directed northerly along 9th Ave S. Stormwater continues northerly along gth Ave
S and eventually discharges into Shell Creek about 0.85 miles downstream of the site. Shell Creek continues
north/northwesterly and eventually discharges to the Puget Sound about 1.6 miles from the site.
ln the immediate vicinity of the project site some of the existing catch basin along 98th Ave SW have jumps
between the intake and outlet elevations in which the outlet pipe are 0.1 to 0.2 ft above the inlet pipes.
These are very minor jumps and the overall elevation drop between the connecting catch basins range from
1 ft to 2 ft and thus the minor jumps through the catch basins are insignificant to the overall capacity of the
downstream system.
Minor areas of run-on from the residential properties south of the site may occur; however, these flows are
primarily from lawn areas and are considered insignificant.
The downstream system consists of a man-made pipe and catch basin system within 0.85 miles of the site;
0.85 miles from the site the stormwater system discharge to Shell Creek. No apparent flooding or system
inadequacies within downstream of the site were discovered during site visits or research of the
downstream system.
See attached watershed and downstream drainage facility map for the local downstream path.

The detention vault system will discharge via a quadplex pump system (4 pumps) due to the lack
of gravity outfall system available to the site. The proposed control pump system configuration
includes four pump act¡vation switches that activates pumps at design stages as the detention
vault system fills. Each pump shall alternate to work each pump equally and extend the life of
the system; see Stormwater Pump Design section below for a full detail summary of the pumps
design.
Below is a stage summary of each pump on condition:

Stormwater Pump Design.
A quadplex pump system has been designed to controlthe stormwater detention system
discharge. The quadplex system is designed to initiate four different pumps and different stages
to comply with the flow control stormwater control requirements of the project as demonstrated
in tho Stnrmr¡vatcr l\/lndplino Scrtinn ahnvp Thc nrrmn çr;çtem consists of four t4l ZOellef 37!rrr !¡r! rLvr rrrvYurç rb sve!.vr
Series with 1.5" discharge with individual pump operating flow rate of 8.57 gpm (0.0191 cfs).
Each pump is design to pump at the same rate so the system can alternate between pumps and
extend the life of the pumps. Each pump will operate at 8.57 gpm (0.0191 cfs) against 17.5 ft of
total head. Total head calculations and manufacturer documentation for the Zoeller 371Series
(including pump performance curves and specification) are provided below.
Total Head:
Total Head = Static Head + Dynamic Head
Static Head = 97.4ft. - 86.0 ft. = 11.4 ft.
Dynamic Head, use the following equation to determine friction loss:
f :o'20 ^( lool'"l n''"' I"l. c J [t3-.1
where: f = friction loss per 100 ft. of pipe
C = flow coefficient à 150 for PVC
3' =i;1Ltril.meter or pipe, in. ) 1.5 in.
f = .0z0rz(1#)"' (#) = o.73rt. per 1oo rt. or pipe
Restricting Valve = 777 ft. (equiv. length of 1.5 in.)- adiust to restrict flows
Swing Check Valve = 15.0 ft. (equiv. length of 1.5 in.)
ControlGate Valve (open) = L.2ft. (equiv. length of 1.5 in.)
90' Bend (2)=2*1.+ ft. = 14.8 ft. (equiv. length of i-.5 in.)
Tee- Branch Flow = 9.9 ft. (equiv. length of 1.5 in.)
Total Equivalent Pipe for Fitting Losses = 817.9 ft.
Length of pipe between pump and outfall = 16 ft
Dynamic Head = \817.9 ft. + L6 ft.) * 0.73 ft. / ßO ft. = 6.1 ft.
Total Head = t'J..4 ft. (static) + 6.1 ft. (dynamic) = 17.5 ft.
Pump Required Design Performance: 8.57 gpm atI/.S ft. of Total Head

WATER qUAIITY ANALYSIS.
An Oldcastle Stormwater Solutions Perk Filter'" located online and downstream of the detention
vault will provide basic water quality treatment for the project. The sizing (number of treatment
cartridges) of the filter system is based on the on-line water quality flow rates per the WWHM12
modeling (0.0314 cfs) or an annual mass loading capacity of the. The below calculations from the
manufacture indicates that a three (3)- 12" cartridge system within in a 60" manhole Perk Filter
has a treatment capacity of 0.05 cfs and will adequately treat the 2-year mitigated release rate of
online design rate of 0.0314 cfs (on-line 15-minute water quality flow rate, see page C-20) and
mass loading of the 2.093-acre collection basin.

E, CONSTRUCTIONSWPPP REQUIREMENTS:
The project will require grading to construct the proposed building and utilities (including the stormwater
control facilities). Standard erosion control measures are proposed to be used during construction. The
primary erosion and sediment control BMP during construction will be proper soíl stabilization methods.
Exposed soils shall be stabilized by application of effective BMPs that protect the soil from the erosive forces
of raindrops, flowing water, and winei. Applicable practices include, but not limited to, temporarrT and
permanent seeding, sodding, mulching, plastic covering, erosion control fabrics, matting, the early
application of gravel base on areas to be paved, and dust control. The contractor shall select a soil
stabilization method best suited for the particular situation. Stock piles must be stabilized and protected
with sediment trapping measures. ln addition, site containment of exposed soils shall be sustained by using
silt fence barriers along the down-slope boundaries of the site's disturbance areas. See the site
development plan for details.
Construction Stormwater Pollution PreventÍon Plan (SWPPPI: The following is a summary of the site's
erosion control measures that evaluates the typical DOE 13 elements of a SWPPP:
Element 7: Mark Clearing Limits: Clearing limits have been delineated on the engineering site development
plans.
Element 2: Establish Construction Access: A construction access has been delineated on the engineering
site development plans.
Element 3: Control Flow Rates: During construction silt fencing will provide attenuation of site runoff and
upon project completion and stabilization (established lawns and landscape of exposed soils).
Element 4: lnstall Sediment Controls: Filter fabric fence has been delineated and detailed on the
engineering site development plans. At a minimum, silt fence will be installed along the down
gradient perimeter of the disturbed area that will receive sediment-laden runoff.
Element 5: Stobilize Soils: Soils will be stabilized per the TESC notes listed on the engineering site
development plans.
Element 6: Protect Slopes: Exposed slopes shall be stabilized per the TESC notes listed on the engineering
site development plans.
Element 7: Protect Drain lnlets: Drain inlet protection will be installed on all catch basins that will receive
sediment-laden runoff. See the engineering site development plans for locations and detail.
Element 8: Stobilize Chonnels ond Outlets: This element is not applicable since there are no temporary
channels or outlets proposed.
Element 9: ConÛol Pollutonts: Pollutants shall be managed as described in the TESC notes listed on the
engineering site development plans.

Stormwater Site Plan Report
Page E-1
Element 10: Control De-Watering: Highly turbid or contaminated de-watering water shall be handled
separately from stormwater. The water from all de-watering systems for trenches and
foundations shall be treated or disposed prior to discharging from the site.
Element 77: Maintain BMP's: BMPs shall be maintained and removed at the end of the project as follows:
i. All temporary and permanent erosion and sediment control BMPs shall be inspected,
mairrtained and repaired in accordance with the Drainage Manual or as approved or
required by the City to assure continued performance of their intended function in
accordance with BMP specifications.
ii. The applicant may remove temporary BMPs when they are no longer needed.
iii. All temporary erosion and sediment control BMPs shall be removed within 30 days after
construction is completed and the City has determined that the site is stabil¡zed.
Element L2: Manage the Project: The owner of the site is responsible for managing the installation and
maintenance of the site BMPs.
Element L3. Protect Low tmpact Development BMPs: No LID stormwater BMPs are proposed
ConclusÍon: The total site disturbance area of the project is greater than one acre, thus a formal Notice of
lntent appl¡cation for NPDES coverage will be made to the Department of Ecology prior to the start of
construction. The final site development construction plans include specific grading and drainage
improvement notes and details. With proper installation, maintenance and inspections of the proposed
construction the project should have minimal impact to the surrounding environment.

These guidelines are intended to provide operation and maintenance instructions for the project's storm
drainage control facilities. The owner is responsible for maintenance of storm drainage facilities within
the property (private property owner system); the owner is not responsible for maintenance within the
public right-of-way (City system).
Private property owners are responsible for properly maintaining the stormwater infrastructure on their

private property owners are properly maintaining their stormwater systems.
This manual is not comprehensive; although it explains the intended operation of the various
components of the drainage system, and suggests a routine of inspection and maintenance, it cannot
anticipate every problem. Once a historical record of maintenance is established, it may be prudent to
alter the routine. lt is recommended that maintenance records be kept, and that the records be
reviewed periodícally.
The onsite detention vault system, control structure, storm filter, storm pumps, junction catch basins,
and conveyance pipes are to be privately maintained by the project residences (all 10 lots). Maintenance
shall include the removal of sediment from the detention vault system, using a vactor truck or equally
effective method. Regular inspections of the control structure within the catch basin shall be conducted
to detect if non-routine maintenance is required due to sediment or debris blocking or clogging the fixed
orifice or standpipe inlet. Regular sediment removal from the catch basins with a vactor truck or equally
effective method shall be conducted as determined by regular inspections. Regular inspection and
maintenance of the storm filter should occur according to the attached maintenance tables from the
Washington State Department of Ecology Stormwater Manual (Volume V) and the attached
maintenance guide from Oldcastle Stormwater Solutions Perk Filter'" system and storm control pump
system are also attached on the following pages.
Semi-annual inspections shall be conducted to ensure proper operations of the drainage system. The
inspections should occur prior to the winter rain season (Oct/Nov), leaving sufficient time to correct any
detected maintenance problems, and at the end of the season (April/May) to determine the effect of
the season's runoff. Once a historical basis is developed the frequency of inspection may be modified as
necessary. Sedíment can build up inside control structures and catch basins, blocking or restricting flow
to the inlet. To prevent this problem, these structures should be routinely cleaned. Regular inspections
of control structures should be conducted to detect the need for non-routine cleanout.
MAINTENANCE REQUIREMENTS
ECDC Section I 8.30.090 requires privately-owned
stormwater rìunagement facilities, such as LID
BMPs be properly maintained. The owner of the
property is the responsible party for such
maintenance. The system must be kept in good
working order. The entire system should be
inspected once per year. An improperly maintained
BMP may cause private ploperty or stltet flrxlding.
Contact the City Engineering Division for
naintenance infonnation.
The City nray make periodic inspections of BMPs to
en$ure tlìey are operating properly. ECDC Section
I 8.30. 100 contains the enforcement provisions the
City can nse to ensure tlrc systent is properly
nraintained.

PerkFllter I lnrpection and Maintenance Guide
PerkFilter* Media Filtration System
Descrlption
The PerkFilter is a stormwater tteatment device used to Íemove pollutants from urban runoff. lmpervious
surfaces and other urban and suburban landscapes generate a var¡ety of contðm¡nänts that can enter
stormwäter and pollute downstrêam receiving waters. The Pe¡kFilter is a media-filled cartridge filtration
device designed to capture and retain sediment, gross solids, metals, nutrients, hydrocarbons, and trash and
debris. As with any stormwater treãtment system, the PerkFilter requires regular periodic maintenance to
sustain optimum system performance.
Functlon
The PerkFilter is a water quality treatment system consisting of three chambers: an inlet chamber, a filter
cartridge treatment chamber, and an outlet chamber (Figure I ). Stormwater runoff enters the inlet chamber
through an inlet pipe, curb opening, or grated inlet. Gross solids are settled out and floating trash and
debris are trapped in the inlet chamber. Pretreated flow is then directed to the treatment chamber through
an opening in the baffle wall between the inlet chamber and treatment chamber. The treatment chamber
contains media-filled filter cartridges (Figure 2) that use physical and chemical processes to remove
poltutants. During a storm event, runoff pools in the treatment chamber before passing radially through
the cylindrical cartridges from the outside surface, through the media for treatment and into the center of
the cartridge. At the center of the cartridge is a center tube assembly designed to distribute the hydraulic
load evenly across the surface of the filter cartridge and controlthe treatment flow rate.The center tube
assembly discharges treated flow through the false floor and into the outlet chamber. A draindown feature
bu¡lt into each cartridge allows the treatment chamber to dewater between storm events.

All PerkFilter systèms include ¿ high flow bypass assembly to divert flow exceeding the treatment capacity
of the filter cartridges around the treatment chamber.The bypass assembly routes peak flow from the inlet
chamber directly to the outlet chamber, bypassing the treatment chamber to prevent sediment and othe¡
captured pollutånts from being scoured and re-entrained by high flow. Treated flow and bypass flow merge
in the outlet chamber for discharge by a single outlet p¡Pe.

Confrguration
The PerkFilter ¡tructure may consist of a vault, manhole, or catch basin conñguration. Catch basin units
may be fabricated from concrete or steel. lnternal components including the PerkFilter cartridges are
manufactured from durable plastic and stainless steel components and hardware. Allcartridges are l8
inches in diameter and are available in two heights: 1 2-inch and 18-inch. Cartridges may be used alone or
may be stacked (Figure 3) to provide 2¡l-inch and 30-inch combinations. The capaciry of each cartr¡dge or
cartridge combination is dictated bythe allowable operating rate of the media and the outer surface area
of the iartridge.Thus, taller cartridges have greater treâtment capacity than shorter cartridges but they also
require more hydraulic drop across the system. Cartridges may be filled with a wide var¡ety of med¡a but the
standard mix is composed of zeolite, perlite and carbon (ZPCI.
Access to an installed PerkFilter system is typically provided by ductile iron castings or hatch covers. The
location and number of access appurtenances is dependent on the size and conñguration of the systêm.

basis and maintained as necessary to ensure performance and protect downstream receiving waters.
Maintenance prevents excessive pollutant buildup that can limit system performance by reducing the
operat¡ng capacity and increasing the potential for scouring of pollutants during periods of high llow.
lnspection ond Malntenonce Frequency
The PerkFilter should be inspected on a regular bas¡t typicâlly tï\,ice per yeâr, and ma¡ntâined as required.
lnitially, inspections of a new system should be conducted more fiequently to help establish an appropdate
site-specific inspection ftequency.The maintenance ftequencywillbe driven bythe amountof runoff and
pollutant loadíng encountered by a given system. ln most caset the optimum maintenance intervalwill be
one to three years. lnspection and maintenance activities should be performed only during dry weather
periods.
lnspectlon Equipment
The following equipment is helpfulwhen conducting PetkFilter inspections:
. Recording device (pen and paperform, voice recorder. iPad. etc.). Suitable clothing (appropriate footwear, gloves, hardhat, safety glasses, etc.). Trafñc controlequipment (cones, barricades, signage flagging, etc'). Socket and wrench for bolt-down access covers. Manhole hookor pry bar. Flashlight. Tape measure. Measuring stickor sludge sampler. Long-handled net {optional)
lnspectlon Procedures
PerkFilter inspections are visual and may be conducted from the ground surface without entering the unit.
To complete an inspection, safety measures including trafñc control should be deployed before the access
covers are removed. Once the covers have been removed, the following items should be checked and
recorded (see form provided at the end of this document) to determine whether maintenance is required:
. lnspect the internal components and note whether there are any broken or missing parts. ln the
unlikely event that internal parts are broken or missing, contact Oldcastle Stormwater Solutions at
{800} 579-8S'19 to determine appropriate corrective action.. Note whether the inlet pipe is blocked or obstructed.The outlet pipe is covered by a removable
outlet hood and cannot be observed without entering the unit.

ãccumulated floating oils is a matter of judgment. However, if there is evidence of an oil or fuel spilf
immediate rnäíntenance by appropriate certiñed personnel is warranted.. Observe, quantiry, and record the average accumulat¡on of sediment in the inlet chamber ãnd
trêatment chamber, A calibrated dipstick, tape measure, or sludge sampler môy be used to determ¡ne
the amount of accumulated sediment in each chamber. The depth of sediment may be determined
by calculating the differe nce between the measurement from the rim of the Perktilter to the top of
the accumulated sediment and the measurement from the rim of the PerkFilter to the bottom of the
PerkFilter structure. Finding the top of the accumulated sediment below standing water takes some
pract¡ce and a light touch, but increased resistance as the measuring device is lowered toward the
bottom of the unit indicates the top of the accumulated sediment.. Finally, observq quantify, and record the amount of standing water in the treatment chamber around
the cartridges. lf standing water is present, do not include the depth of sediment that may have
settled out belowthe standing water in the measurement.
MalntenanceTr¡ggers
Maintenance should be scheduled if any of the following conditions are identifred during the ¡nspect¡on:
. lnternal components are broken or missing.. lnlet pipíng is obstructed.. The accumulation of floating trash and debris that cannot be retrieved with a net and/oroil in the
inlet chamber is significant.. There is more than 6"of accumulated sediment in the inlet chamber.. There is more than 4'of accumulated sediment in the treatment chamber.. There is more than 4"of standing water in the treatment chamber more than 24 hours after end of
rain event.. A hazardous material release (e.9. automotive fluids) is observed or reported.. The system has not been maintained for 3 years (wet cl¡mates) to 5 years (dry climates).

Contact Oldcåstle Stormwater Solutiont at {800} 579-8819 for rep¡ôcement filter cårtr¡dges. A lead time of
four weeks is recommended.
Maíntenance Procedures
Maintenance should be conducted during dry weather when no flow is entering the system. Confined space
entry is necessðry to maintain vault and manhole PerkFilter configurations. Only personnel that are OSHA
Confined Space Entry trained and certified may enter underground structures. Confined space entry ¡s not
required for catch basin PerkFilter configurations. Once safety measures such as traffic control are deployed,
the access covers may be removed and the following activities may be conducted to complete maintenance:
. Remove floating trash, debris, and oils from the water surface in the inlet chamber using the
extension nozzle on the end ofthe boom hose ofthe vacuum truck. Continue using the vacuum
truck to completely dewater the inlet chamber and evacuate all accumulated sediment from the inlet
chamber. Some jetting may be required to fully remove sediment. The inlet chamber does not need
to be refilled with water after maintenance is complete.The system will fillwith waterwhen the next
storm event occufs.. Remove the hold-down strut from each row of ñlter cartridges and then remove the top of each
cartridge (the top is held on by four 9/16" bolts) and use the vacuum truck to evacuate the spent
media. When empty, the spent cartridges may be easily lifted off their slip couplers and removed
from the vault. The coupler$ may be left inserted into couplings cast into the false floor to prevent
sediment and debris from being washed into the outlet chamber during washdown.. Once allthe spent cartridges have been removed from the structure, the vacuum truck may be used
to evacuate all accumulated sediment from the treatment chamber.Some jetting may be required
to fully remove sediment. Take care not to wash sediment and deblis through the openings in the
false floor and into the outlet chamber. All material removed from the PerkFilter during maintenance
including the spent media must be disposed of in accordance with local, state, andlor federal
regulations. ln most caset the material may be handled in the same manner as disposalof material
removed from sumped catch basins or manholes.
' Place a fresh cartridge in each cartridge position using the existing slip couplers and urethane
bottom caps. lf the vault is equipped w¡th stacked cartridges, the existing outer and inner
interconnector couplers must be used betwean the stacked cartr¡dges to provide hydraulic
connect¡on.Transfer the existing vent tubes from the tpent cartr¡dges to the fresh cartridges. Finally,
refit the struts to hold the fiesh cartridges in place.. Securely replace access covefs, as appropriate.. Make arrangements to return the empty rpent cartr¡dges to Oldcastle Stormwater Solutions.
