Q:l Minimuml Standardl 7
Answer:
Cutl andl Filll Slopes
rougheningl thel surfacel ofl thel slopel decreasesl runoff,l lowersl thel velocityl runoff,l
increasesl waterl retention,l andl leadsl tol betterl seedl germination
slopesl thatl arel foundl tol bel erodingl excessivelyl withinl onl yearl ofl permanentl
stabilizationl shalll bel providedl withl additionall slopl stabilizingl measuresl untill thel
probleml isl corrected
Q:l Minimuml Standardl 8
Answer:
Concentratedl Runoff
shalll notl flowl downl cutl orl filll slopesl unlessl containedl withinl anl adequatel temporaryl orl
permanentl channel,l flumel orl slopel drainl structure
outletsl ofl thesel drainsl needl outletl protectionl tol preventl erosionl froml thel concentratedl
flow
sizel ofl pipel dependsl onl drainagel area
temporarilyl conductl concentratedl stormwaterl runoffl safelyl downl thel facel ofl al cutl orl
filll slopel withoutl causingl erosionl onl orl belowl thel slope
Q:l Minimuml Standardl 9
,Answer:
Waterl Seeps
wheneverl waterl seepsl froml al slopel face,l adequatel drainagel orl otherl protectionl shalll bel
provided
cutl andl filll operationsl mayl exposel shallowl aquifersl orl groundwaterl tablesl froml whichl
waterl mayl seepl throughl thel sidel ofl al slope
Q:l Minimuml Standardl 10
Answer:
Inletl Protection
alll storml sewerl inletsl thatl arel madel operablel duringl constructionl shalll bel protectedl sol
thatl sediment-ladenl waterl cannotl enterl thel conveyancel systeml withoutl firstl beingl
filteredl orl otherwisel treatedl tol removel sediment
storml sewersl arel designedl tol efficientlyl transportl stormwaterl awayl froml thel site,l sol
whenl sedimentl entersl thel storml sewerl system,l twol negativel effectsl canl occur:
1.l whenl velocityl ofl flowl isl high,l muchl ofl thel sedimentl willl bel quicklyl transportedl tol
thel nearestl receivingl channel
2.l whenl velocityl ofl thel flowl isl low,l thel sedimentl mayl bel depositedl inl thel pipesl
resultingl inl cloggingl andl potentiall floodingl ofl al sitel duringl storml events
preventsl sedimentl froml enteringl storml drainagel systemsl priorl tol permanentl stabilizationl
ofl thel disturbedl area

Answer:
Blockl andl gravell dropl inletl -l willl havel tol cleanl outl regularlyl butl won'tl getl damaged.
Q:l Minimuml Standardl 11
Answer:
,Outletl Protection

adequatel outletl protectionl andl anyl requiredl temporaryl orl permanentl channell liningl shalll
bel installedl inl bothl thel conveyancel channell andl receivingl channel
preventl scourl atl stormwaterl outlets,l protectl outletl structure,l andl minimizel potentiall forl

Q:l Minimuml Standardl 12
Answer:
Watercoursel Construction
whenl workl inl al livel watercoursel isl performed,l precautionsl shalll bel takenl tol minimizel
