Introduction
What is Stormwater Runoff?
When urban and suburban develc�ment covers t�e land with buildings, streets and parking lots,
much of the native tiopsoil, duff, trees, shrubs and grass are replaced by asphalt and concrete. Rainfall
that would have soaked directly into the ground insfiead stays on the surface as stormwat� runoff
making its way into starm drains (including man-made pipes, dibches, or swale networks), stormwater
ponds, surface and groundwaber, and eventually to Puget Sound.
What is a Storm Drain System and how cbes it work?
The storm drain system for most developments includes measures to carry, store, cleanse, and
release the sfiormwat;er. Compon�ts work tagether to reduce the impacts of development on the
environment Impacts can include floading which results in property damage and blocked emergency
routes, erosion which can cause damage to salmon spawning habitat, and pollution which harms fish
and/or drinking water supplies.
The storm drain system provides a safe method to carry stormwater to the treatment and sto��e
area. Swales and ponds filber pollutants from the stormwater by physically settling out partides,
chemically binding pollutants to pond sediments, and biologically converting pollutants to less harmful
compounds. Ponds also st�re treated water, releasing it gradually to a nearby stream or to
groundwater.
What does Stormwater Runoff have to do with Water Quality?
Stormwater runoff must be treated because it carries litter, dl, gasoline, fertilizers, pesticides, pet
wastes, sediments, and anything else that can float, dissolve or be swept along by moving water. Left
untreated, poluted stormwater can reach nearby waterways where it can harm and even kill aquatic
life. It can also polute groundwater to the ext�t that it requires treatrnent before it is suitable for
drinking. Nationally, stormwater is recagnized as a major threat to water quality. R�nember to keep
everything out of stormwater systems except the rainwater they are designed to collect.
Your Stormwater Facility
Differ�t types of ponds are designed for different purposes. For example, wet ponds primarily
provide treatment of stormwat�. Dry pands or infiltration ponds are designed to provide storage for
stormwater and allow for its gradual release downstream or into the ground.
Who is Responsible for Maintaining Stormwater Faalities?
All stormwater facilities require mainte.nance. Regular maintenance ensures proper functioning and
preserves visual appeal. This Stormwater Facility Maintenance Guide was designed to e�cplain how
sta-mwater facilities work and provide user-friendly, straightforward guidance on facility maintenanoe.
You are responsible for regularly maintaining privately awned ponds, cabch basins, pipes and other
drainage facilities on your property. Stormwater facilities located in public rights-of-way are
maintained by local governm�ts.
How to Use the Stormwater Facility Maintenanoe Guide
This Maintenance Guide includes a Site Plan specific to your development and a Facility Key that
identifies the private stormwater facilities you are responsible for maintaining. A "Quick List" af
1
maintenance activities has also been included to help you identify the more routine needs � your
facility.
Included in This Guide
• Comprehensive Maintenance Checklists that provide specific details on required maint�ance
• Pollution Prevention Tips that list ways to protect water quality and keep storm drain systems
functioning smoothly
• Resources to provide more information and technical assistanoe
A Regionai A�roach to &tormwater Management
The Cities of Yelm, Lac�, Olympia, and Tumwater, together with Thurston County, are taking steps
to educate and involve area residents in water quality issues and stormwater management.
Stormwater runoff is a widespread cause of water quality impairment and stream degradation. The
jurisdictions are wwking together with residents, businesses, community groups and schools to
address this problem. This guide focuses on providing information ai ways that you can reduoe
stormwater impacts through polution prevention and proper facility maintenance.
YOUR STORMWATER FACILITIES
Reference the Site Plan for the locations of the stormwater componen�s requiring maintenance.
QUICK LIST
The follawing is an abbreviated checklist of the most common types of maintenance required. Please
go over this checklist after heavy rains. The list represents minimum maintenance to be performed
and should be completed in c�junctian with the other checklists for an effective maintenance
program.
• Remove any twigs, leaves, or other materials from the roadway surface.
• Inspect roof drain inlet and outlet pipes for blockages. Clear all blockages.
• Inspect areas down-gradient of all raof downspout splash blocks. Ensure that there is positive
drainage down and away from the splash blocks. Repair any eroded areas and re-establish
vegetation.
Maintaining Stormwater Facilities
All stormwater facilities need t� be maintained. Regular maintenance ensures proper functioning and
keeps the facility aesthetically appealing. This Stwmwater Faci�ity Maint�rance Guide was designed to
he)p explain ha,v stormwater facilities work and provide user-friendly guidance on how to maintain tfiem
to ke� them up to standards. As a facility owner or homeowner's association, you are responsible for
regularly maintaining your privately-owned drainage facilities such as ponds, cabch hasins and pipes.
Local governments maintain sU�rmwater facilities lacated in public roadways.
Maintenance Check�ists
The checklists in this guide are far yau to use when inspecting and maintaining the stormwater facilities in
your neighborhood. If you are missing a particular checldi�, or if you have additianal facilities not
identified or addressed in this guide, please contact your developer or local jurisdiction.
2
The checklists are in table format for ease of use and brevity. Each checklist tells you what part of the
feature to check, how dten to check,what to check for,and what to do abaut it. Log sheets are included
to help you keep track of when you last surveyed the storm drainage system.
Although it is not intended for the maintenance survey to involve anything tao difficult cx strenua.�s,there
are a few tools that will make the job easier and safer. These tools include:
• Gloves.
• A flashlight(to look into catch basins, manholes or pipes).
• A long pde or broom handle for checking sediment depths (see below).
• Some kind of pry bar or lifting toal for pulling manhde and grate covers.
A listing of resources is also induded within this packet (see next page). Here you will find the phone
numbers of tt�agencies r�erred-to in the tables.
SAFETY WARNING:
Due to OSHA regulations, you should never stick your head or any part of your baly inta a manhole or
other type of confined space. When laoldng into a manhde or catch basin, stand above it and use the
flashlight to help yau see. Use a pole a broom handle that is long enough when you are checking
sediment depths in confined spaces. Always properly replace grates and lids.
NO PART OFYOUR BODY SHOIlLD BREAKTHE PLaNE OFTHE OPEN HOLE

Glossary of Stormwater Terms
Best Management Practice5(BMPs) — Structural features or procedures that reduce the
adverse impacts of develapment on the quantity and/or quality of runoff water.
BiofilteC (SWa1e) — A wider and flatter vegetated version of a ditch over which runoff flows at a
uniform depth and velocity. Biofilters perform best when vegetation has a thick mat of
ro�s, leaves,and stems at the soil interface(such as grass).
Biofiltration—The process through which pollutant concentrations in runoff water are reduced by
filtering runoff through vegetaGon.
BufFer—The zone along a sensitive area that provides protection and stability for the area's
functioning. As an integral part of a stream or wetland ecosystem,the buff�-provides shading, slope and
bank stabilization,and input of organic d�ris and coarse sedimenfis b�streams. It allows raom for
variation in aquatic system boundaries (due to hydrdogic or climatic effects), attenuation of surface
water flows from precipitation and stormwat�runoff, habitat for wildlife, and protection from harmful
disturbance or intrusion by humans or domestic animals.
Catc� Basin —An inlet box set into the ground, usually rectangular and made of concrete,capped
with a grate that allows stormwater to enter. A sump in the bottom catiches sediment.
Chedc Darn—A dam (of rock, logs,etc.)built in a gully or drainage channel to reduce flow velocity,
minimize erosive scouring, prom�e sediment deposition,and/or enhance inFltration.
COmpost StOrmwatet' Filter — A treatment facility that removes sediment and pollutants from
stormwater by percoiating water through a layer af spetially-prepared Bigleaf maple compost. Clean water
exits the bot6am af the facility through a pipe, while stormwat�flows in excess of the facility design
overflow the compost bed and bypass the facility.
Constructed Wetland—A wet pond with dead storage at various depths and planted with wetiand
plants to enhance its treatment capabilities.
Control Structure or Flow Restrictor—A manhde and/or pipe structure with a flow-
regulating or m�ering device such as a weir or plates with small hdes known as orifices. The structure
controls the rate at which water leaves the pond.
Conveyance— A mechanism or device for transporting water, including gutters, pipes,channels
(natural or man-made), culverts, manholes, etc.
Critical At'eas— Areas such as wedands, streams, st�eep slopes, etc., as defined by ordinance or
resolution by the jurisdiction. Also known as environmentally-sensitive areas.
CulVelt—A conveyance device(e.g. concrete, metal or plastic pipe) which conveys water from a
ditch,swale, or stream under(usually xross)a roadway,driveway or embankment.
Dead Storage — TI� volume of storage in a pond below the outlet which does nat drain after a
starm event. This pool provides treatrnent of the stormwater by allowing sediments to settle out.
17
Detention Facility- A facility (e.g. a pond,vault, or pipe) in which surface wat�or stormwater
is tempaearily stored.
Detention Pottd — A detention facility in the form of an open pond.
Dispersion Trench - An open-top trench filled with rip rap or gravel that takes the discharge
from a pond,spreads it out,and spills(bubbles)the flow out along its entire length. Dispersion trenches
are used to simulate"sheet flaw"of stormwater from an area, and are oft� used to protect sensitive
areas.
Dt'ainage System — A combination of facilities for the cdlection,conveyance,containment,
treatrr�ent,discharge and/or disposal of stormwater runoff.
Drop Structure— A structure for dre�pping water to a lower elevation andjor dissipating energy. A
drop may be vertical or inclined.
Dry Pond — A det�tion facility that drains completely afGer a storm. This type of pond has a pipe
oudet at the bottom.
Easement— A lega) encumbrance placed against a property's title to reserve access. Qrainage
eas�nents typically provide access to pipes andJor ponds, and are generally 15 to 20 feet wide.
Emergency Overflow or Spitlway—An area on the b�p edge of a pond that is slightly lower in
elevation than areas around it, and is normally lined with riprap for erosion protection. The emergency
overflow is used only if the primary and s�ondary outlets of the pond fail,
in the event � extreme storms, or if the infiltration capability of the pond becomes significantly
diminished. If the emergency overflow ever comes into play, it may mean that the pond needs to be
upgraded.
Energy Dissipater— A rock pad at an outlet(of a pipe,channel,etc.)designed to slow the flow
velocity, spread aut the water leaving the ou�et, and reduce the potential for erosion.
Freeboard — The vertical distance between the design high wat� mark and tf�e top of a pond (or
other structure). Most ponds have one to two feet of freeboard to prevent them from overflowing.
Infiltration —The soaking of water through the soil surface into the ground (percolation is essentially
the same thing). Many ponds are designed to inflltrabe or retain stormwater,and thus do not have a
regularly used discharge pipe.
Infiltration Facility(or Structure}— A facility(pond or trench)which re�ains and percolates
stormwater into the ground, having no discharge(to any surface water) under normal operating
conditions.
7unCtion —Pant where two or more drainage pipes or channels converge(e.g. a manhde).
7u1'isdiCtion — City of Yelm(as applicable).
18
Lined Pond or Conveyance—A facility,the botta�n and sides of which have been made
impervious(using,for example,a plastic liner or clay/silt soil layer)to the transmission of liquids.
Live Storage— The volume of storage in a pond above the outlet,which drains aftier a storm event.
This storage capacity provides flood contrd and habitat protection for nearby streams.
Manhole— A larger version of the catch basin,often round with a solid lid. Manholes allow access tio
underground pipes(such as storm sewers)for maintenance.
Natural Chanttel— A stream,creek, river, lake, wetland,estuary,gully, swale,ravine, or any open
conduit where wat�will concentrate and flow intermittently or continuously.
Oil-Water Separator — A structure or device used to remove oil and greasy solids from water.
They operate by using gravity separation of liquids that have different densities. Many catch basins have
a down-turned plastic elbow that provides some oil-water separation.
Outfall— The point where water flows from a man-made conduit,channel,or drain into a water body
or other natural drainage feature.
Retention Facility— A f�ility that is designed to retain water and allow for infiltration.
Retention Pond — A retention facility that is an open basin or"pond."
Revetments— Materials such as rock or keystones used to sustain an embankment,such as in a
retaining wall.
Riprap— Broken rock,cobbles,or boulders placed on earth surfaces, such as on top of a berm for the
emergency overflow,along steep slopes, or at the outiet of a pipe,for protection against the erosive
action of water. Also used for entrances to construction sites,to prevent sediment tracking.
Runoff— The portion af water originating as precipitation that becomes surface flow. See
"stormwater"below.
Sand Filter— A treatment facility that removes pollutants and sediments from stormwater by
Rercolating stormwaterthrough a layer of sand. Clean water exits the bottom of the facility through a
pipe.
Stormwater—The portion of precipitation that falls on prope�-ty and that does not naturally percolate
into the ground or evaporabe,but flows via overland flow, interflow, pipes or other features into a defined
sutface water body or a constructed infiltration facility. Stormwater includes wash-down water and other
wastewater that enters the drainage system.
Swale—A shallow surface drainage conveyance with relatively gentle side slopes,generally with flow
depths less than 1 foot Essentially a broad, flat-bottomed ditch. See°biofilter."
19
Trash Rack or Bar Screen —A device(usually a scre� or bars)that fits aver a pipe opening fio
prevent large debris such as rocks or branches from entering and partially blocking the pipe.
Wet Pond —A stormwater treatment pond designed with a"dead storage"volume to maintain a
continuous or seasonal stntic water level below the pond outiet elevation.

INTRODUCTION
AB�UT THIS MANUAL
The City ofYelm's«ater resources—its streatr�s, lakes,��etlands, grotu�dwater, and Pu�et Sound
— p]ay ail important role in the quafity of l�e we enjoy. They provide us with recreation and
drillcu�e water; support tourrm and salmon and are used by industry. These ���ater$, however,
are vul�ierable to polhtion from a tivide variety ofhutnan activities.
This inarival appl�s to those resiciential properties and activities fl�at have the patential to
coritrlbute poIlutants to starm�vater nma� or drectly to receiv�g waters. Stormwater
nma�rnay seep into the ground, drain to a storm c�-ain or a drainage ditch, or flo�v over t�e
ground. Regardless of the way runoffleaves your site, it ends up in a stream river, lake,wetland,
gxound�ater or Puget Sound.
ContazYiu�ated stormwater can negatively affect every water body it enters. Therefore, this
ma27taalpravides deta�ed i�1f'ormation on«�hat you can do to rzduce the containination ofsurface
water,groundwater, and storm��ater fror�i your property.
�Iany of aur ���ater po3l,rtition probl�xxns are due gi large part to pollutants«ashed o�the land by
stom�s. The quality of "stortn«�ater" from residential properti�s is an increasing concern
nation�vide. �fany peaple believe tllat stormwater is "clean" and does not hartn�vater quality.
This perception is tm,derstandable smce the amount ofpol�.ition from any one p}ace is not usually
si��icant by �self But wlien aIl these small a�nounts are coinbuled, t�i�y can eause s�tnifieant
pollution prob�ns.
The fzderal Ckan Water Act mandates that citi�s and counties coritrol d� quality of stornzwater
nmo� One �vay to achieve t�i� is to implement polh�tion prevention measur�s on mdividual
properties. By foIlo�vu� the `Best Mar�ernent Pract�es"descr�bed in this manual you can do
your part to protect our strearns, groundwater, and Puget S outki.
BEST MAlV AGEMENT PRACT'ICES ... ��HAT ARE THEY?
Best Management Practices (B��iPs)are a set of activ$ies desi�ied to reduce stortnwater
poIlution BMPs are �eparated inta two broad categor�s:source control and treatmerit.
Souree Control BMPs
Svrrrce cvritrol B'1�IPs prevent contatxiu�ants from enteritig stortxi�vater nmo�by controlling
th�xi at the source. Some sourc� control BMPs are operatianaL such as ch�king regularly for
leaks and drips from equip�ient and vehic�s, covering Ynaterials that have potential to add
poIlutants to surface «ater if rainwater comes u1 contaet with t�� inatet��ls, cleulu� up pet
�vaste; and minitn�ing use of pesticides, fertllizers, atid nisecticides. Other source eontrol
B1�7Ps require use of a structure to prevent ran�vvater frotn contactit�g materials that w�71
1
corrt�inix�ate stormwater runoff such as provide a covered area or berm to prevent clean
storn�water from enteru�work or storage areas.
Sour�ce con��Aol BMPs prel�ent contamiyzants from entef�ing
stor��n�Jatet• b� controlling them at the so�rrce.
Treatment BVIPs
In contrast, treatments BMPs are stnzetures that h-eat stonm�ater to remove contamu�ants.
Treatrnent BMPs typieaIly require elaborate plarulii�, C�eS1gi1 � COIlSttl7ChOYL A stor�nwater
pond for your subdivision is an example of a treatntent B�1P. No treatment BMP is, capable of
removvuu�g 100 �ercent of the contatnu�its i7 stonn«ater and the ]ess contaIrrinants in the
starmwater prior to the treatment BMP,t�ie more eff�ctive the BMP is.
tllso remember that,just because there is a storm�vater eollection system where you}ive, �does
not necess�y mean �at the storrnwater is treated. Marry developments �vere created prior to
requireinents ta treat storrrnvater. 1�ie nmofffrom your property may go dgectly or indirectly to
a strearn or«retlai�without any treahnent.
Keep in n�ind that t°zrno,f,f f�°om 1Jou�°p�Aoperty rr�ay go directly of�

�e ne ral Principles of Pollution Preve ntion
Tl�e�e a��e 1 S gene��al p�inciples of pollution pr�e�lentzon that
ei}ery liomeol�inef�slioz�ld consider.
This section descn�bes sinple pollution prevei�tion princi}�les that every hotneo�vner should
consider. Most of these are corr�non sense, "housekeeping"types of sohrtions. Wfh collective
actian by it�dividuals throu�hout tl�� county in unpkrnenting these prnciples, the mpraveinent
m�vater quality can be substantiaL There are 15 general principles of pollution preventian.
1. Avoid the activity or reduce its occurrence
Avoid �otentially pollut� ac�rity or do it kss frequently, especially � it takes place
outdoors. Apply la�un care cheYYUCaIs follo«irig directions and only as needed. Do not apply
herbicides right before it rains.
2. 11JIove the activity indoois
Ilfiove a potentially polluting activity uidoors out of the weather. Tlvs prevents nuioff
contarnination and provides more control for a c�anup �a sp�7l.occurs. For example unlaad
and store chetnicals inside a �arage ar�a or shed instead of outside. Be safe and ensure any
storage area is�vellvent�7ated and required building arul fire code requgements are met.
3. Cleanup sp�lls quickly
Promptly conta�and cleanup solid and liquid pollutant leaks and spills on arry exposed soil;

and then sweep up the matcrial and dispose of it al t�ie garbage. Prorr�dy repair or replace
leal.ing earniectians,�ipes, hoses,valves, etc. on vehicles and equipinent you own.
�. Use less material
Don't buy or use more inaterial thari you really need. This not only help$ keep potential
disposal, storage and polhrtian problems to a miturnum, but will probal�ly save you money
too.
5. Use the least toxic materials available
Itrvestigate the use of materials that are less toxic. For example; replace a caustic-type
detergeiit or solvent�vith a inore eiiviromnentally fi-iendly product Even ifyou do s�u�ch to
a biodegradab� product, remetnber that only uncont�ninated «rater is allo�ed to et�ter the
storm«ater drau�age systerxi.

Remember- that only uncontaminated water is allowed to ente�°
the sto�mwater drainage system.
6. Create and maintain�egetated areas near activity locatians
Z�egetation can filter polluta,tlts out of stortnwater. Route sto�tn��ater frotn parking an,d u�ork
areas through vegetated areas. Rerriember that «astewater other than stormwater nino�
such as «ash water, must be discharged to a �vaste�vater callection systern (se�ver or septic
system), and may not be discharged to a storm drainage systern.
7. Locate activities as far as possible from surface drainage paths
Activiries Iocated as far as poss�ble from known dra2n,ag� paths such as d�ches, strean�s;
other water bodies, and storm drau�s wiIl be �ss ]�cely to pol�zte, s nce i��viIl take longer for
material to reach the drama�e features. This give more time to react to a spill, or i�'it is a
`2�ousekeepulg" �sue, may protect the local«aters long enough for you to clearru� the area
around t�ie activity. Don't for�et that ground�vater protzction is importarrt throughout �e
Gity ofYehn, no matter where the activity is bcated, so the actions you take vn a day-to-day
bas�area always important, even in dry weather.

Pollutants can eancentrate over time in storm drair�age facilities such as catch bas�s, ditches,
arid stonn drains. When a large storm event occtu�s, turbu]ent runo$can rnobill¢e these
�oIlutants and carry them to receivu� waters. By perfonnulg regular inanitenance on
stormwater ficilfies located on your properiy you can prevent this from occurrit�. Also
repair or replace cracked or otr�en�ise datna�ed pavernent m parking areas arkl any other
drairrage areas that are subjeet to�oltutant material leaks or spills.
9. Reduce, reuse,and recycle as �uch as possible

Household Hazardous Material use, Storage ana
Disposal
Once �ve reaIly start bol�irig around our houses, �e ainotult of hazardous materials we have on
site is a real eye-opener. O�l based pau7ts and sta�s, paint thinner, gasoline, charcoal starter
f�.ud, cleaners, cv�es, pesticides, f�zgernail polish remover, and ��ood preseroatives are just a
few l�zardous material�that most ofus have around the house.
When products such as these are dutnped on the grour�d ar in a storm drain, they can be �vashed
directly to receiving waters �vhere they can harm fish and wilcilife. They can also u�fi�rate into
the graund and contatninate dririkn� �vater supplies. The saine problein can occur if they are
disposed of with your regular garl�age; the containers can leak at the IandfiIl and contaminate
ground��ater. The same type of contatnnati�n can also occur if hazardous products are poured
down a sink or toilet into a septic system. Don't pour them down the draiti ifyou're on murnc�al
se�vers, either. Many compounds can `�ass t�7rough" the waste�uater treatxnent plant ��ithout
treatment and cantainuiate receivir�g waters, or they can harm the bi�log�al process used at the

Pet Waste M anage me nt
Pet waste that washes into lakes, strean�s or Puget S ound begins to decay, us� up oxygen and
releasing aintnonia. Low oxygen levels and at7unonia cotnbn7ed with ti�arm water can k�l.fish
Pet waste also conta��s nutrients that encourage �ueed and al�ae gxowth in waters we use for
s�vimrni�, boat� and fishmg. Most �nportantly, um many urban areas, pet waste is $ie largest
source of bacterial loadin� to strean�s. It can carry diseases that could inake water unsafe far
contact and lead to beach closures or affect shellfish harvest. These a�ch�de:
• Caznpylobacteriosis bacterial irr�fectxin
• SalmaneIlosi�—bacterialirifection
• Toxocariasis—round�vorm infection
• Toxop]asmosis—protozoan parasite infection
• Giardiasis—protozoan parasite infection
