RE. Paving Waiver Request for US West NewVector - Paving Waiver Request #PW035 -
Planning Department File #BB-43-95
Dear Mr. Miilgard:
After review of the paving waiver request applicatron, #PW035, that was provided to us by
Richard Bianchi of Bianchi Dustrud Partnership for the tower/fuel tank facility to be located
on a portion of the site at 10207 E. Buckeye Lane, SCAPCA makes the following
recommendation.
it is SCAPCA's opinion that leaving the leased srte unpaved will not adversely affect air
quality. These recommendations are based on the facts listed below.
1 The site is within the Spokane County PM10 non-attainment area. However, based
on the information provided in the application and the facts listed below, air quality
impacts are expected to be minimal.
2. Traffic to the site will be minimal. About one trip every 30 days is expected.
3. The application indicates that gravel will be used on the leased site.
4 Portions of the travelled areas wili be paved, and the unpaved area wiil be fenced.
The proponent is responsible for ensuring that all of SCAPCA's regulations are complied with.
This includes ensuring that particulate matter is not emitted from their unpaved surfaces in
sufficient amounts to cause an annoyance to any other person when deposited upon real
property of others. Also, it is unlawfui to allow dirt and/or mud to be deposited on paved
roadways open to the public without promptly removing such dirt and/or mud.
if you have questions or comments do not hesitate to call me at (509)456-4727 ext. 102.

U.S. West NewVector Building & Tower
East` 10207 Buckeye,Lane

tlie architect, it is-my recommendation that the Paving Waiver be approved as requested.

~ AGRA Earth & Environmen t In
ta ~ c, (AEE) is pleased to present the results of our Subsurface
Exptoration and Geotechnical Engineering study conducted for the above referenced project. Our
~ services have been performed in accordance with the scope of work contained on our Confimnation
of Budget and Scope of Work letter to you dated 14 February 1995. Authorization to proceed with
this study was given in your facsimile transmittai dated 8 February 1995. This report has been
~ prepared for specific application to this projeci by US West Nev#Vector Group and their agents, in
accordance with generally accepted geotechnical engineering practice.
~ SITE AND PRaJECT DESCRIPTION
The project site is located in the East 10400 Block of Montgomery Drive in ihe Spokane Valtey, in
the NW 1/4 of Secdon 8, T25N, R43E in unincorporaied Spokane County, Washington. The sfte is
~ bordered by railroad right-of-way to the north, undeveloped lots to the east and west, and asphaltic-
concrete paved Buckeye l.ane to the south. The southern majority of the sde is relativety flat, wdh
the northern margm rising moderately to the north, with total topographic relief estimated to be on
~ the order of 20 feet. No surface water was observed on the site at the time of our explorahon
program. The property lines of the subject parcel, as well as the approximate locations of the test
pits aocomplrshed for this study are shown on the Site and Exploration Plan, Figure 1. Test pit logs
~ with Interpretive descnptions of subsurface conditions encountered at the exptoration locabons are
also attached.

parking areas and aocess drives wll be inctuded in site development. Water and sewer services are
reportedly currently stubbed at the southwest comer of the property, and power and gas are
reportedly avaitable near the intersecfion of Darbmouth Lane and Montgomery Orive.
` Subsurfaoe Exploration Program
r Our field exploration program for this study conststed of digging seven backhoe-excavated test pits
r Ot1 the ptOjeCt Site. The approxtmate locagons are illustrated on the Site and ExpioraVon Ptan, Figure
1. The test pits were excavated with a rubber-tired backhoe under subcontract to our firm, and
ranged in depth from 7 to 10 feet befow the ex,sting ground surface. The test pits were continuousty
R obsen►ed and logged in the field by a geotoglcai engineer from our firm. Test pit locations wefe
obtained by string-tine taping and pa+cing wdh dje and of a hand-held compass from property comers
that had been established by others prior to our expioration program, and should be considered
accurate to the degree implied by the methods used.
. ~ .
R The test pit logs encfosed with this letter are based in interpretat~ons made in the field and lndicate
~ various types of soils and materials encountered in the test pits. The retative density of soils
indtcated on the logs are interpretire descriptions based on the excavation characterisUcs,
evaluation of ihe excavated soils and stabiiity of the trench sidewalls. The logs indicate the depth
tT of sUata or where characteristics of the straie changed, although changes indicated may be gradual.
The nature and extent of variagons in subsurface condrtions between the test pit locaflons may not
~ become evident untif construcgon. if variations then appear evident, jt may be necessary to
e~ reevaluate the recommendatlons of this report.
SUBSURFACE COND1T10NS
The subsurface exploranon program for this ptoject consisted of advancing seven backhoe-
ex,cavated test pits to depths ranging from 7 to 10 feet betow existing adjacent grades to evaluate
soii conditions. Deiaited interpretive logs of the matenals encountered in our explorabons are
attached to this report.

Soil conditions exposed m the lest pits advanced across the site were fairly consistent, and generally
disclosed loose to medium dense, tan-gray, sand, gravet, cobbles and boulders to the full depths
~r explored. A topsoil horizon was absent from all test pits locations except TP-1, where an
approximately 9 inch thick organic-rich topsoil layer was observed. The granular soii deposit was
interpreted to represent allwium deposited by ftood waters that covered the Spokane area several
~ times in the geologic pasL We obsenred bouiders greater than 3 feet in diameter at various locations
on the site, apparently generated dunng past gravel mining actnrities. Bouldets are considered
typical in Spokane Valley sediments, such as those present on this site, and boutders of varying

~ A 12-inch diameter steel pipe was encountered In test pft TP-1 with invert etevation approximatety
4 feet belvw existing site grades. This pipe may have been part of a previousiy existing inigadon
system, and is reportediy not a part of the high-pressure petroleum product plpeline that is marked
between the site's northem boundary and the railroad dght•of•way to the north.
Groundwater seepage was not encountered in our test pits at ihe time of excavation, and site so11s
appeared to possess moisture contents at or below moisture conterrtts necessary for adequate
compaction if the site soils are to be utilized as structural fill. Groundwater conditions and soil
moisture contents can be expected to vary, depending upon changes in season, precipftagon
pattems, stte utilization, both on and off-stte, and other factors.
T CONCLUSIONS AND RECOMMENDATIONS
i
We understand that the proposed project consists of construcUng of a one-story, grouted CMU block
, communications buildjng and a 125 feet tall, 3 legged, self supporbng cormmunications tower, with
associated paved parking areas and access drives. Based on the subsurface condiflons
' encountered In our iest pits, the proposed project appears feasible from a geotechnical standpoint,
provided that measures are taken to remove and recompact the existing site soils, or replace them
21 with suitably compacted structural fi11 beneath foundations, pavements and floor stabs, to provide
a suiiable bearing sirata far founding the proposed improvements.
~ Site Prepa~ation
Based on our undersianding of proposed site grades, we assume that the proposed improvemeMs
~ will be matched dosety with eaustiing site grades. Prior to site grading, any site surface water runoff
and groundwater seepage shouid be collected and routed away to a proper drainage In order to
facilftte work and subgrade constructon. Once surface and groundwaier are controlled, all btniding,
' tower foundation, pavement, srdewalk and aN other areas to be graded should be clesred of all
grass, weeds, brush, sod, topsoil and uncontro(led fiII materiats. We estimate that the thickness of
the crganic-nch upper layer will be vanable in the area to be developed, but will likety be less than
~ the 9 inches observed at the TP-1 location over the southern majority of the site. After removal of
any existmg soft soils, uncontrolled fifi and other deleterious materials In the areas to be developed,
~ ihe resulitng excavations should be backfilled with uStructural FiII" as outlined in this report. The
topsog generated during the strrpping process may be stoclpiled for re-use in landscape areas, or
wasted off-site rf exce.ssnre quantities of orgarncs are present. tt shoutd be noted that if stripping Ls
done dunng wet weather or wet site conditions, the volume of disturbed matenal may be Increased
considerabty due to softening of the siltier portions of the underlying site sojls.
Stripping of vegeiadon and unsuitable soils should reveal loose to medium dense sandy gravels,
~ cobbtes and boulders with variable silt contents, based on aur exptorations. Upon compledan of
IL stripping, the loose to medium dense sandy gravels In the areas to be filled should be scarffied to

a depth of 6 inches or more and compacted such that the upper foot of the subgrade has achieved
a minimum density of at least 90 percent of the modified Proctor maximum dry density (ASTM:D-
L 1M for the material. Further structural fill discussjons are presented in the foliowing section of this
report. The above assumas UW earthwork v+nli be performed during relatively dry summer weather.
. As is typical with sites containing silty soils, the materiais are moisture sensibve and are readiiy
subject to disturbance when over their opbmum moisture content by more than a few percent Thus,
depP.nding on tlhe judgement of the geotechnical engineer, preroiling of the subgrade may be waived
to avoid softening of the natural subgrade. Any soft, wet or organic-rich soils disclosed by preroliing
should be removed and repiaced wtth structural fill as discussed telow.
To reduce site dLsturbence, the contractor should minim¢e traffic over prepared subgrade areas, and
direct site surface and groundwater away frorn work areas. In wet site condftions, the use of a
worldng surface of quarry spalts may be required to protect the subgrade, especially from vehicular
traffic.
Structural Fiii
All fili material placed in buitding, pavement, and non-landscaped areas, and for backfiil of utility
tremhes, should be placed in accordance with the recommendations herein for structural fiil. Prior
to structural fili placement, the surfaces to receive structural fill should be prepared at a minimum
as previousty described. All structural fill should be free of organic material, debrts, and other
defeterious matenals. The lndividual parUcle size of soiis used for fiii should be less than 6 inches
in diameter. Site soils can be used as structurai fiII provided Uheir moisture condiiions permn
compacgon to recommended relative densities presented below. Moisture contents should be
expected to vary in both lateral and vertical extent across the site.
Structural flll should be placed in Ofts no greater than 8 inches in loose thickness and each lift shoutd
be compacted to a minimum of 90 per+cent of the modified Proctor maximum dry density as
detemnined by the ASTM:D-1557 test procedure. All sUuctural fill below foundations, floor siabs, and
paved areas shouid be compacted to at least 95 percent of the abave maximum. We recommend
that a representative of AEE be present during gradhng, so that a suitable number of in-place density
tests may be conducted as sUvctural fill piacement occurs. In this way, the adequacy of earthworic
may be evaluated as it proceeds.
The suitabiidy of soiis for sUuctural fill use depends pnmarity on the gradation and moisture content
~ of the soil when it is placed. As the amount of fines (that soil fraction passing the U.S. No. 200
sieve) lncreases, soil become increasingiy sensitive to small changes in moLsture content, and
adequate compaction becomes more difficult or impossible to achieve. Generatly, soils containing
more ftn about 5 pencent passfig the No. 200 sieve, by weight (based on the soil fraciion passing
the U.S. No. 4 sieve), such as some of those present on this sfte, cannot be compacted to a firm and
non-yielding condition when the moisture content is more than a few percent above optimum. The

wt optimum moisture content is that which yields the greatest soii density under a gnren compactive
j effort. It should be assumed that the site soits will be below optimum moisture content dunng much
~ of the year.
~ The use of on-sde sods for structural fiil will require strict control of rnoisture content during grading.
Setective drying of over-optimum silty soits rnay be achieved by scaurifj►jng or windrowing surticial
materiats during extended periods of dry weather. Solls which are dry of optimum may require
i- moisture to be added by the use of water trucks and thorough blending to facilitate a uniform
~ moisture distribution prior to compaction.
In the event that inctement weather or wet site condiflons preciude the use of on-site soils or non-
~ select materials as stuctural flli, we recommend that only pclean", free draining coarse sand, gravel
or a sand and gravel mixture be used. "Clean" free draining import fill should also be used for ali
backfill within three feet of any below-grade and retaining walls. If "clean° import Ml is required
~ durin9 wet site or wet weather conditions, such materiats shouid generally contain less than 5
percent passing the No. 200 sieve, based on that soil fraction passing the U.S. No. 4 sieve, with a
minimum of 50 percent retained on the No. 4 sieve, and shouid not contain discrete particles greater
, than 6 inches in diameter. It should be noted that the placement of structurai fill is in many cases
weather dependenL Delays due to inclement weather are common, even when using select granutar
flii. We recommend that site grading and subsurface ublity work be scheduled for the dner months,
if at all possible.
SHALLOW FOUNDATIONS - EQUIPMENT BUILDING
We recomrnend ubiidng an aliowable bearing pressure of 2500 pounds per square foot for shallow
footings founded in the loose to medium dense sands and gravels wjth varying cobble and boutder
contents encountered at our exploration locations. We recommend the equipment storage buiiding
footings be at least 3 feet deep for frost protecUon. Equipment building foundagon subgrade soUs
shoutd be compacted to a firm and unyielding condihon, v+nth a minimum compacted density of at
least 95 percent of the modified Proctor (ASTM D1557) maximum dry density for the material. A
minimum of 1 foot of suitable site soils or imported granular fill soils should be placed atop the
prepared subgrade end compacted to the degree referenced above Total equipment buiiding
foundation setdements shouid be less than 3I4 of an inch, with differengal setttements on the order
of one-haif of the total setttements wdh foundation subgrade preparation performed as per ihe above
recommendaUons. M AEE representative should be onsite to observe subgrade preparation and
fiII placemeat procedures, and perform a sujtable number of m-place density tests on the compacted
, subgrade and overlying structural fill tayer for the above settlement estimates to be considered vatid.

A maucimum allowable verUcal bearing capacity of 5,000 pounds per square foot (psf) may be used
~ for mat foundafions constructed wnth a mmimum embedment of 6 feet and into undisturbed, sandy
~ gravel, cobbte and boulder soils. The subgrade should be proof-rolled, moisture conditioned if
necessary, and compacted with suitabty sized equtpment such that a fimn and unyielding surface is
~ achteved. A minimum of 2 feet of suttable site soits, compacted to a minimum of 95 percent of the
J modified Proctor ma~cimum dry density, should be placed atop the prepared subgrade to provide a
I surface suitable for support of the above referenced allowable foundation bearing pressure. The
structural fill pad should extend outside the edges of the proposed equipment buiiding and tower mat
foundativns a distanoe at least equal to the depth of the fill pad, in order to provide uniform support
~ within 81 vertical to 1 horizontal prism extending downward from the lower outboard edges of the
foundators. The pnepared subgrades should be obsenred by an AEE representative, to verity that
the actual foundation subgrade conditions are consistent with these assumed during preparation of
_ these recommendadons. The recommended allowabie bearing capacity may be increased by one-
thlyd to resist short-term transient loads such as wind and seismic forces. The anUcipated uplift
loads may be resisted by a large concrete mat foundation servjng as a dead weight.
~
Laterai or shear loads appred to the footings may be resisted by a combination of passive pressure
against the side of the footings and/or shear fnction resistance along the base of the foundation.
Passive pressures may be expressed as an allowable fluid pressure of 300 pounds per square foot
per foot of embedment into undisturbed native sands and gravels, or properiy compacted structural
,
fill composed of site soils. We recommend that the upper 2 feet of structural fill, prepared as
presented below, be neglected for passive pressure resistance. For concrete cast against the
compacted sand and gravel bearing surface, we recommend that an allowable base friction
coefficient of 0.40 be used in design.
DEEP FOUNDATION - TOWER
Based on the conditions encountered in our exploraiions, it appears feasible to consiruct
convenUonal dritled pier foundation elements for tower support. Hard drilling conditions shouid be
~ expected due to the gravef, cobbles and bouiders encountered 1n our test pits. The pier consVuction
' contractor should be prepared to remove boulders from the pier excavation to the full depth of the
foundatlon. The foundahon conVactor should be prepared to case the entire length of deep
foundations, to prevent caving and maintain cantinuity of foundation concrete. Since our
, exploratons were performed with a conventional backhoe due to schedule and budgei constrants,
we cannot veriiy subsurfaoe conditions at the likely depths of deep foundation etements at the time
of preparation of this report. The allowable deep foundation end.beanng and skin frichon values
` presented below were developed for another project nearby the subject site, founded in the sam
ailuvial deposit, and appear to be appropriate for the site soiis, based on the conditions observed
in our test pits. We should be allowed to verify that subsurface condMons are in accordance with
~
the assumptions and methods uUlized in formulating the foliotinnng recommendations for the values
contained therein to be valid.

For vertical bearing capacity of dritled pters, we recommend using the foilowing values for bearing
capaclty, for assuming e minimum of 8 feet of embedement below the existing ground surface:

14 to 30 feet 3.3 D/8 13 TSF
Where 0IS embedement (in feet) into each layec, and B Is the diameter of the pier in feet.
For frictional reststance, acting both downward and in upiift, we recommend using the following
811owabte skin friction values. These recommendations are for thai portion of the pier embedded
telow 2 feeL If the c.asing used Is to be left in place, the annular space between the casing and tt►e
sides of the pter excavation should be compietely filled with concrete for the following skin friction
values to remain valid.
Embedment 8elow the Ground Surface A11owable Skin Friction (~TS)
2 to 14 feet 0.25 TSF
14 to 30 feet 0.40 TSF
For lateral pressures, we assume the pier wnll be relativety rfgid and will act as a pofe. The
interacdon between a pole and the soil Is complex, and may be modelled by elastic methods. The
passive pressure approach presented hereln Is more sUrafght-forward, and Is conservative by
neglecting redistribugon of vertlcal stress and shear force at the pler bottom which would likewise
~ serve to re.sist lateral loads. We recommend using an aDowable passive pressure of 300 pounds per
cubt foot (expressed as an equivalent fluid unii weight), acting over 2 pier diameters wide by 8 pier
diameters deep, neglectlng the upper most 2 feet of embedment below the ground surface.
According to NAVFAC Design Manual 7.2, a lateral deflection equal to about 0.005 times the pier
length would be required to mobilize the allowable passive pressure presented above. Higher
detlection woutd rttobilize higher passive pressures. The factor of sefety with respect to ultimate
passive pressure Is 1.5, which Is commonty applied to transient Hnnd or seLsmic loads.
Stab-On-Grade Ftoors
" The slab-on-grade floor subgrade should be prepared in accordance with the previous site
preparation recommendations. The slab-on-grade subgrade should be founded on pre-rolled and
compacted native soii, overiain by a minimum of 2 feet of structurat fill compacted to a minimum of
95 pencent relative density, as stated above. Any existing undocumented fiII should be removed to

on the No. 4 sieve, and a maximum particle size of 1 inch. This fill is intended to serve as a capillary
break. An Impervious moisture baRier shouid also be inciuded between the slab and the capillary
break matedal. A few fnches of sand on top of the moisture barrier can help reduce damage to the
barrier material during the slab pour and finishing operation, provide a levellmg course below the
' slab, and aid in curing of slab concrete if dampened immediatety before stab concrete placement.
• The stab should be isolated from walls and columns to reduce the effects of possibte differential
~ settlement
' Psvement Design Criteria
Pravided below are general recommendations regardjng asphali pavement design. It must be
recognized that pavement design is a compromise between high IniUal cast with low maintenance
on one side, and lower initfal cost coupled with the need for periodic repairs and higher long-temn
maintenance on the other side. As a result, the owner should take part in the development of the
appropriate paving section. features which govem the performance of the pavement inciude:
the stabtlity of the soil subgrade; the presence or absence of moisture, free water and organics in
the subgrade; the fines content of the subgrade soits; the iraffic volume; and the intended use.
8esed on the faidy consistent density and composition of the materials encountered in our
explorations in the mwgins of the buildtng area on the site, when coupled with the anficipated traffic
loading, we recommend that the access drivelparking area be founded direcily upon the existing
mat,eriais. Following stripping, we recommend that the upper foot of the subgrade material, as weil
as a minimum of 1 foot of suitable site sals vr imported granular fill be compacted to a ftrm and
` unyielding condition at a density not less than 95 percent of the modified Proctor maximum dry
densiry (AS111A D:1557). Piacement of base course can proceed direcUy upon a subgrade prepared
in such a manner. We ere available to provide supplementary recommendadons during construction
ff candibans fi pavemertt subgrade areas are encountered that are different than those encountered
in our explorations.
Based on the soil types, moisture, and density conddions encountered in our explorations, we
ne=mmend the following minimum pavement sections be considered for this project, founded in a
subgrade prepared as per the above recommendations:
Car Parking Areas:
3 inches asphaltic concrete, over
4 inches compacted crushed rock
Access Ddves. Truck Lanes:
4 inches asphalac concrete, over
6 inches compacted crushed rock

lt rtmt be realized dW the above recorturiended pavement sections are minimum sections for a 20-
year deslgn I'~fe, and wiil requlre pedodic miuntenance, as we11 as likely resurfacing wnthin that design
life. The following asphatt equivalency factors may be used to devetop altemative pavement
secgons:
1 inch of asphalt concrete=
2 inches of crushed rock=
2.7 inches of gravel base course.
Drainage Considerations
The near surface sitie soUs are somewhat silty and highly susceptible to disturbance when wet. We
reoommerd that the contractor take precautions to maintain a dry construction site and protect the
subgrade from d[sturbance. Water from precipitaUon or seepage should be controlied wtth
interceptor trenches or pumped sumps, as needed.
Final sfte grades should be set so that water does not coilect adjacent to the completed structures
or atop paved surfacas. Instead, the ground surface shouid be sloped downward away from all
butldtngs, parWng aneas and retaining walis so that surface water runoff may be carried to a sultabte
discharge point. We recommend that the bufiding be provided with a perimeter foundation drain
systern to collect any seepage water. This drain should consisi of a perforated pipe within an
envetope of pea gravel or washed rock extending at least 6 inches on all sides of the pipe, and
surrounded by fiiter fabnc. The drain should encircle the extenor of all foundaton walls at or below
the level of the footings and all subfioor utitities which could be affected by groundwater seepage.
Trie drainage systems shouid discharge by tightline to a storm sewer or other suitable discharge
point, ideally by gravity. Roof and surface runoff water shoutd not discharge into the foundation draln
system. Instead a separate tighUine drain system or direct discharge to the ground with sptash
blocks should be used.
It appears Ukely that disposal of roof and/or parking lot runoff via drywells may be considered.
Runoff from bituminous coated or asphalbc-concrete paved surfaces wjll need to be directed into
grassy swales prior to overflowing into shatiow inJection wells (drywells), in accordance with the
Spokane County "Guidelines for Stormwater Management Site so11s have been mapped as
betonging to the GaRison-Marble-Springdale associaUon (Garnson graveily loam, 0 to 20 percent
~ slopes) in the Soil Survey of Spokane County, Washington (USDA Soit Conservation Senrice, 1968).
The soils encountered in test pits TP-3 through TP-7 appear suitable for disposal of stormwater via
' subsurface infilVation by shallow lnjection welis (drywelis), in our opirnon.

CLOSURE
The conclusions and recommendabons contained in this report are based on the exploraUons
accomplished for this study and on our understanding of the project. The number, locagon, and
depth of our exptorations were completed within the site, schedule, and proposal constraints so as
to yietd the information used to formutate our recornmendations. The integrity and performance of
~ the foundations, floor slabs and pavements depend largely on the proper site preparation and
construcbion proaedures, aEE is avallable to provide geotechnical engineering servlces during the
design phases of the worK as vvell as soffs and materials testing services throughout the earthw+orlc
and construction phases of the project. If variations in the subsurface condittons are obsenred at
that time, AEE woutd be abte to provide additlonal geatechniCat recommendations to minimize delays
as the proJect develops.
We appreciate the opportuniiy to be of corgnued senirce to US West NewVecior Group, Inc. on this
project and would be pleased to discuss the contents of this report or other aspects of the project

Subject: SCAPCA COMMENTS REGARDING : 95003315
Following is a Iist of concernsfissues that, at a minimum, need to be addressed for this project.
SCAPCA encourages proponents to contact their offices at 1101 West College, Spokane, WA
99201 for additional information.
~ All air pollution regulations must be met.
* Air pollution reAulations require that dust emissions during demolmon, construction and excavation
proJects be controlled. This may require the use of water sprays, tarps, spnnklers or suspension
of activrty dunnp certain weather conditions. Haul roads should be Veated and emissions from
the uansfer of earthen matenal must be controlled as well as emissions from all other construcUon
related activities.
* SCAPCA stronely recommends that all uavelled surfaces (i.e ,,ngress, eeress, par{unA areas,
access roads) be paved and kept clean to minimize dust emissions.
Measures rnust be taken to avoid the deposiUon of dirt and mud from unpaved surfaces onto
paved surfaces. If trackinA or spills occur on paved suifaces, measures rnust be taken immediately
to clean these surfaces.
* Debns generated as a resuh of this project must be disposed of by means other than burning li.e.,
construction waste, etc...1.
Failure to meet SCAPCA regulations may result in delays, closure and crvd and/or criminal sancUons.

Itefer to the 1" = 20' Drainage Map for the actual basm locaUons and bouadanes
For the proposed dralnage ponds with 3 1 side slopes, the pond volwne can be calculated wrth two
components the volume dvectly above the pond soor plus the votume above the side slopes To
compute the volwne at any ponduig depth, only two parameters need to be lmown pond floor area
aad pand floor pemneter length (both ate specified on the Topography aad Drainage Plan rnap)
Voluma is Galculated at 6" depth for "208" treatme,nt and at 8" depth for stocage, as follows
At 6" depth
Pond Volume =(0 5 ft depth x pond floor area) +(1/2 x 0 5 x 15 x pond floor penmeter)
=05 A+0375 P
At 8" depdh.
Pond Volume =(0 67 ft depth x pond floor area) +(l!2 x 0 67 x 2 0 x pond floor penmeter)
