SWM Plan Reviewer
What is the belief that Environmental Site Design is grounded in?
Environmental stability can be maintained as new groups are evolved during our watersheds if
primary principles are obeyed.
Describe the evaluation between the vintage view of stormwater and Environmental Site
Design's view of stormwater.
The vintage view of stormwater was as a waste product in want of disposal, however ESD
perspectives stormwater as a precious useful resource that have to be used cautiously
In the field of stormwater management, what does (Tv) stand for?
Treatment quantity
In the sphere of stormwater control, what does (LID) stand for?
Low Impact Development
What could (TP) stand for as regards to BMP Pollutant Removal Effeciencies?
General phosphorus
In the sphere of stormwater management, what does (EMC) stand for?
Event Mean Concentration
In the sector of stormwater control, what does (MTD) stand for?
Manufactured Treatment Devices
In the sphere of stormwater control, what does (HSG) stand for?
Hydrologic Soil Group
In the field of stormwater management, what does (CN) stand for?
Curve Number
What is a filter strip (Design Standard 2)?
,Vegetated Areas that treat sheet flow brought from adjacent impervious and managed turf
regions by means of slowing runoff velocities and allowing sediment and connected pollutants to
settle and /or be filtered by way of the plant life.
What is soil healing or soil compost amendments (Design Standard four)?
A Environmental Site Design Practice carried out after creation to deeply until compacted soils
and repair their porosity with the aid of amending them with compost.
What are vegetated roofs (Design Standard 5)?
Opportunity roof surfaces that commonly include waterproofing and drainage substances and
an engineered developing media this is designed to support plant growth.
What are the 2 sorts of vegetative roofs? What are the variations?
-Intensive vegetated roofs have a deeper developing media layer that tiers from 6" to 4' thick,
that's planted with a wider variety of plant life, including timber.-Extensive vegetated roofs have
a shallower growing media (2-6"), which is planted with carefully decided on drought tolerant
vegetation.
What is permeable pavement (Design widespread 7)?
An alternative paving surface that permits stormwater runoff to filter via voids inside the
pavement surface into an underlying stone reservoir, wherein it's miles temporarily saved and/or
infiltrated.
What four layers could you count on to peer in a permeable pavement?
-Surface pavement layer
-Underlying Stone Aggregate
-Reservoir Layer-Filter Fabric
Which stormwater layout specification has the best runoff discount functionality?
Infiltration practices
What form of websites ought to keep away from the use of Infiltration Practices?
Any website designated as a stormwater hotspot
In the field of stormwater management, what does (CPv) stand for?
Channel protection volume
, Describe the function of stormwater filters (Design Specification 12).
Stormwater filters capture, temporarily shop, and treat stormwater runoff with the aid of passing
it through an engineered clear out media, collecting the filtered water in an underdrain and then
returning it again to the storm drainage device.
What kind of web site could a stormwater clear out be best for?
A small, enormously impervious website
What is a wet pond? (Design Specification 14)
a permanent pool of standing water that promotes a better surroundings for gravitational
settling, organic uptake, and microbial pastime.
In the field of stormwater control, what does (ED) stand for?
Extended Detention
In general, what five categories are the BMPs in comparison on the subject of every different?
-Annual runoff volume reduction (RR)
-Phosphorus/Nitrogen mass load removal
-Phosphorus/Nitrogen EMC discount by BMP remedy technique
-Channel protection-Flood mitigation
In the sphere of stormwater control, what does (RR) stand for?
Runoff Reduction
What 3 design specs are usually used with soil compost amendments?
-Simple rooftop disconnection
-Filter Strips
-Grass Channel
What sort of soils are soil compost amendments generally no longer applicable for? What form
of soils can benefit by using the usage of soil compost amendments?
Hydrologic Soil Groups A and B
Soil Compost Amendments can gain Hydrologic Soil Groups C and D
