Stormwater System
Operations & Maintenance Plan'
DESCRIPTION
;
]
The Stonnwater System contains all runoff within the site. Ail runoff will be disposed of by either infiltrating into the ground or
dispersion into the public stonn system during storm events and high flows. This runoff is collected in roof gutter doWnspouts,
catch basins, area drains, and trench drains. Runoff is then conveyed to infiltration and treatment units through conveyance
swales and an underground piped storm system. Throughout the system are located water quality catch basins. and filtration
basins to treat and infiltrate runoff into the ground. . ,
I
I.
I'
:1
II
,
INSPECTION/MAINTENANCE SCHEDULE
The whole system shall be inspected and maintained quarterly and wilhin 48 hours atter each major storm event. For this
O&M plan, a major storm event is defined as greater than 3.0 inches of rain in 24 hours. All components of the storm system
as described below must be inspected and maintained frequently orthey will cease to function effectively. The facility owner
must keep a log, recording all inspection dates, observations; and maintenance activities.' . '.
FACILITY SUMMARY
;1
li
:1 I
I
The/ollowing components form the stormwater system:
1. Piped Storm System: The piped stonn system consists of all underground pipes that connect the roof downspouts and
catch basins downstream to the manholes and filtration basins.' ,
r
2. Catch Basins: Catch basins are 24.inch square basins used to coiled stonnwater runoff from paved surfaces and
serve as inlets for the filtration basins and piped storm system. 1 .
3, . Kristar FloGuard Catch Basin Insert Filters: Product by Kristar that captures and treats stormwater. See Appendix for
further detail.' .
;'1-
I
I
"1
, I
"
4. Area Drains f Trench Drains: Similar to a catch basin, area drains are 12" square basins that collect stormwater runoff
frol(1landscaped areas. Trench drains are long collection structures that collectstormwater runoff in ramped areas such
as loading docks.
, .'
. Ii
ii'
111,1,'
ii'
Ii,
"i'
..1
(i!
5, Filtration Basins: A Filtration Basin is a small, vegetated depression or pond, Runoff from impervious surfaces enters
the basins through curb spillways (openings) and/or from conveyance swales where it is temporarily stored in a
. reservoir on lop of the soil. Pollutant reduction is achieved as stonnwater infiltrates through' a layer of .vegetation and
growing medium to an "under drain" layer of open graded gravel and a perforated pipe tn"t drains filtered stonnwater to
the stonn system. The basin also has an overflow inlet with a rim set 1" above the bottom of the basin. When'storm
runoff exceeds the swale's infiltration rate and ieservoirstorage depth, it will overflow via the inlet and be conveyed
directly to the storm system.
'INSPECTION/MAINTENANCE PROCEDURE
The following items shall be inspected and maintained as stated:
, . .
1. Piped Storm . .
. Shall be inspected for clogging or leaks at all clean outs and connections to structures.
.. Debris/sediment, oil andgreas~ found to clog the pipes should be removed, and dispo~ed of in accordance with
applicable federal and state requirements.
2. Catch Basins in Pavement
. Shall be inspected for obstructions or debris, which shall be removed upon discovery.
. If over 6" of sediment accumulation is discovered, sediment shall be removed.

4. Area Drain I Trench Drain
. If water ponds over the drain for more than 6 hours after a major storm, the drain grate may be clogged.
. Check for debris/sediment accumulation in and around the drain, rake and remove and evaluate upland causes
(erosion, suriace or roofdebrls, etc.) .
. lithe drain hassettled more than 2-inches, regrade finished ground.around drain to match.
. If the drain and/or grate is damaged, replace or repair as necessary. .
j
5, Filtration Basins'
All ponding stormwater should infiltrate through the basin within 0.5 hours after a storm. All facility components and
vegetation shall be inspected for proper operations and structural stability, at a minimum, quarterly for the first 2 years
from the date of installation, 2 times per year thereafter, and within 48 hours after each major storm event. The facility
owner must keep a log, recording all inspection dates, observations, and maintenance activities. The following items
shall be inspected and maintained as stated: .
af Embankment and Side Slopes retain water in the filtration basin.
. Structural deficiencies shall be corrected upon discovery:
. Slopes shall be stabilized using appropriate erosion control measures when soil is exposed or erosion channels'
are forming.
. Sources of erosion damage shall be identified and controlled.
b) Overflow Catch Basin shall convey flow exceeding reservoir capacity to an approved stormwater receiving system. .
. Overflow inlet and grate shall be cleared when 25% of the conveyance capacity is plugged or blocked.
. , Sources of erosion damage shall be identified and controlled when native soil is exposed ,
c) Growing Media consisting of sandy loam soil and decomposed organic mulch (per the project specifications) shall
allow storm water to percolate uniformly through the basin. If water remains .1-2 hours after storm, sources of possible "
clogging shall be identified and corrected. If necessary the basin shall be excavated and growing medium and under'
drain layer shall be replaced to correct low infiltration rates.
. Holes that are not consistent with the design and allow water to flow directly through the basin to the under drain.
layer shall be plugged.
. Basin shall be raked and, if necessary, restricted sources of sediment and debris shall be identified and prevented.
. Sources of erosion shall be identified and controlled when soil is exposed or erosion channels are present.
d) . Sediment! Debris Management shall prevent loss of reservoir volume caused by sedimentation.
. Sediment accumulation shall be hand removed with minimum damage to vegetation using proper erosion control
.measures. Sediment and debris exceeding 2" in depth shall be removed every 1-2 years or sooner if performance
is affected, or so thick as to damage or kill vegetation.
. Litter and debris shall be removed routinely (e.g., no less than quarterly) and upon discovery.
e) Vegetation shall be healthy, nursery-grown shrubs, groundcover and grasses complying with the approved planting
~~ .
. Following establishment period, vegeta\ion shall be dense enough to protect underlying'soils.
. Fallen leaves and debris shall be raked and removed in October or November each year.
. Shrubs and/or grasses shall be pruned and trimmed in fall and spring to maintain sight distances, pedestrian safety
and to prevent interference with planter operation. .
. Dead or declining vegetation shall be removed and replaced in spring and fall or immediately if required to maintain
cover density and control erosion where soils are exposed. '
. Nuisance or prohibited vegetalion, such as English ivy or blackberries, shall be removed immediately when
discovered. .

GENERALSPECIFICA nONS FOR MAINTENANCE OF.
FLO-GARD@CATCH BASIN INSERT FILTERS
]
SCOPE:
J
Federal, State and Local Clean Wate"r act regulations and those of insurance carriers ~equire that stor~water
filtration systems be maintained and serviced on a recurring basis. The intent of the'regulations is to ensure
that the systems, on a continuing basis, efficiently remove'pollutants from stormwaterruno(f thereby ,
preventing pollution of the nation's water resources. These Spec~fications apply,to the Fio-Gard@catch
basin insert filters:
J
RECOMMENDED FREQUENCY OF SERVICE:
J
Drainage Protection Systems (DPS) reco~mends that installed Flo..:Gard@ Catch Basin Insert Filters be
serviced on a recurring basis. Ultimately, the frequency depends on the amount of runoff, pollutant IO<;lding
and interference from debris (leaves, vegetation, cans, paper,' etc.); however,. as. a minimum, it is
recommended that each installation be serviced a minimum of three' times per year, with a change of filter'
medium once per year. DPS technicians are available to do an on-site evaluation, upon request. .
J
RECOMMENDED TIMING OF SERVICE:
i
I
I
I
I
I
'1
I
I
l
;.
DPS g~idelines for the timing of service are as following:
I. For areas with a definite rainy season: Prior to, during and following the rainy season.
2. For areas 'subject to year-round rainfall: On a recurring basis (at least three times per year)..
3. For areas with winter snow and summer rain: Prior to and just after the snow season and during
the summer rain season.
4. For installed devices not subject to the elements (washracks, parking garages, etc.): On a recurring
basis (no less than three times per year).
J
J
SERVICE PROCEDURES:
J
I, The catch basin shall be visually inspected for defects and possible illegal dumping." If illegal
dumping.l}as occurred, the proper authorities and property owner representative shall be notified
as soon as practicable. .
2. The catch basin grate will be removed and set to one side. Then either:
a. ~n industrial vacuum shall be used to c~efully remove all sediment and debris ~rom '
the filter porti~n of th~ unit, or
b. By grasping the filter's stainless .steel frame, the entire filter shall be carefully removed
from the catch basin. The filter medium pouches shall then be removed by unsnapping
the tether from the D-ring and set to one side. 'B.eing careful not to spill,Jhe contents
shall be removed: .
3. The filter liner, gaskets, stainless steel frame and other components shall be in~pected for
continued se:rviceability. Minor damage or defects f<;Jund shall be corrected on-the-spot and a
notation made 00 the Maintenance Record. More extensive deficiencies that affect the efficiency
of the filter (torn liner,'etc.), if approved by the customer representative. will be corrected and an
invoice supmitted to the representative along with the Maintenance Record.
4. The filter meqium pouches shall be inspected for defects and continued serviceability and replaced
as necessary. See below. -
5. If removed, the filter device shall be replaced in the catch basin and the grate replaced.

REPLACEMENT AND DISPOSAL OF EXPOSED FILTER MEDIUM AND COLLECTED
DEBRIS
]
The frequency of filter medium pouch exchange will be in accordance with the existing DPS-Customer
Maintenance Contrac~. DPS recommends that the medium be changed at least once per year. During the
appropriate 0ervice, or if so determined by the service technician during a non-scheduled service, the filter
medium pouches will be replaced with new pouches. 'Once the exposed pouches and debris have been
remQved, DPS has possession and must ~ispose of it in a~cordance with loc~l, state and federatagen~y
requirements. .
]
]
Note: As ti!e ge~erator, the limdow'ner is' ultimately re~po~sible for the proper disposal of the" exposed
filter medium alld debris. Because the filter medias "likely contain petroleum hydrocarbons, heavy
metals alld other harmful pollutants, the materials must be treated as an EPA Class 2 Hazardous. Waste
and properly disposed oj. DPS relieves the landowner of the actual disposal task, and provides
. certification of its completio"n in accordance with appropriate regulationS.
J
J
DPS also has the capability of servicing all manner of catch basin inserts and catch basins without
inserts, underground oiVwater separators, stormwate~ interceptors and other such devices. Ali DPS .
personnel are highly qualified technicians and are confined space trained and certified. Call us at
-(888) 950-8826 for further information and assisiancc.

Land Use Compatibility Statement (LUeS)
What is a LUeS? A Land Use Compatibility Statement (LUCS) is the form. ODOT uses to ensure that Highway Approach Permits are
consistent with local land use requireme.nts.
Why is a LUeS Required? ODOT Coordination Rules, OAR 731-015, identify Highway Approach Permits as permits that affect land
use. State Jaw requires ODOT activities that' affect land use to be consistent with ackno~edged local comprehensiye plans...
When is a LUeS Required? An ODOT LUCS must be submitted with every ODOT Highway Approach Permit Application.
How to Complete the LUeS: The applicant completes Section 1. Sectio~ 2 must b,e completed by the local jurisdiction. The
applicant then submits the completed LUCS to ODOT as part of the Highway Approach Permit Application.

SPRINGFIELD, OREGON'
4.2. Existing Verstis Proposed Runoff FI~ws
An anaiysis of the '25-year storm was conducted to determine fiow values (OJ" in'cubic feet per
~ ~.
second (cis). The existing :site has two points of discharge, one for the, trench drain at the
driveway and one that collects flow from the rest of the site (per the 'survey) and discharges into
the 12" storm line on Main Street. The proposed site plan has three discharge points, one for the
. Irench drain at the driveway (any change' in' area ""as considered minimal and therefore'
disregarded for these calculations), and two for the flow from the'rest of the site (one discharges'
to Ihe 12" line in Main St. and the other from 'the filtration basin to the 18" storm line' in 68th
place). The following table presents the analysis for the pre'vs. post- flows (excluding filtration)
for the two connection'-points'considered.

The pr~posed design .includes a ~Itration basin. The increase in flow is only 0.05 cfsfor, the 25-
year storm, which will be reduced through infiltration through the media and discharge will be
equal to or'less than existing fiows. Therefore, the increase in impervious area discussed in
Section 4:1 is negligent. ' . ".

'Several spreadsheets based 6n the Santa Barbara Urban Hydrograph Method are used in the'
calculation of. this 'report, These spreadsheets were used for the corlVeyance.and peak runoff
calculations. .
The spreadsheets used for the water quality calculations meet the. criteria outlined in the City of
,Portland's SWMM and have been approved by the City of Portland Bureau of Environmental Services
(BES) on similar projects KPFF has completed in the past.
Precipitation data for the-respective storms are City of Springfield design storms.

_' 6. PROPOSED STORM DRAINAGE IMPROVEMENTS
The proposed improvements for. the Springfield FS will meet or exceed all requirements of the Springfield
Development Code and the City of Springfield Public Works Engineering Design Standards and Procedures
Manual (EDSP). .
"
The proposed storm drainage system consists of surface inlets to coiled surface runoff and an underground
storm drainage pipe network to convey the collected runoff as shown jn the Storm Utility Map drawing, ST-2
found in Appendix A. Filtration basins and water quality catch basins provide water quality treatment of the site
.impervious. surfaces. The private on-site storm drainage will connect to the proposed public storm drainage
system iit the property line. ' .
6,1, Water Quality
Filtration Basins'
Approximately 35% of the non"building rooftop (NBR) stormwater. runoff from the improvement area of the
. site will be treated using filtration basins. Filtration Basins are similar in design to the Vegetated Infiltration
. Basin as described in the City of Portland's Stormwater Management Manual. The filtration basins provide.
primary treatmentby holding runoff and allowing pollutants to settle as the runoff infiltrates through eighteen
inches of engineered filtration soil. After the runoff is filtered through the filtration soil, the water is collected
in filter fabric wrapped clean drain rock and then collected and conveyed by perforated piped to the trapped
catch basin located within the filtration basin area. The filtration soil layer is specified io achieve a 6-in/hr
infiltration rate and the basins are ,sized to fully infiltrate the runoff from the water quality storm event.
During events greater than the water quality storm, the stormwater will accumulate within the basins, up to ,
. 1-inch of depth. After the accumulated depth reaches 1'inch, thestormwater in the basin will overflow into.
the catch basin that will be set 1 "inch above the bottom of the basin. The basin bottoms are gradedto'.
achieve an even dispersion across the basin. .
A detail for the filtration basin. is on sheet C6:3 of the site review plans, which is included in Appendix A.
The complete water quality calculations and worksheets for the basin is in Appendix Dof this report.
Stormwater Filters
Approximateiy 65% of the NBR for the improved area of the site will be treated with water quality catch
basins. Details for the water quality catch basins are provided on sheet C6.0 of the site review plans,which
are included in Appendix A. '.
6.2. Conveyance
The conveyance system is designed .to convey the stormwater runoff peak flows of 25,year storm event or
greater. Pipe sizes and slopes shown on plans reflect the results of the calculations. The complete
conveyance calcuiations and worksheets are in Appendix C of this report.
7. PROJECT OVERVIEW
This Storm Drainage Report as prepared by KPFF Consulting Engineers (KPFF) describes the concepts and
design intent for stormwater management at the Springfield Fire Station No. 16 in Springfield ~~ IVED.
