Green Infrastructure
Engineered systems that mimic natural features & processes to manage storm impacts, known by the acronym GSI.
What is Green Stormwater Infrastructure
Impermeable surfaces increase these three phenomenon. Tell me TWO.
What is flooding, runoff or urban heat island effect
Founded in 1965 in response to pollution, CRWA (Joanna's workplace) stands for what?
What is Charles River Watershed Association
Name ONE type of GI that has strong educational benefits.
What is a rain garden, green roof, Bioretention, etc. (Not permeable pavement or infiltration).
An EJ community is a community typically defined as an area that "experiences disproportionately high burdens from environmental pollution and/or socioeconomic vulnerabilities, often impacting the health and well-being of residents." What does EJ stand for?
What is an Environmental Justice Community?
Name ONE type of GI:
What is: A rain garden, rainwater harvesting, infiltration trench, permeable pavement, infiltration chambers etc.
Rain and snowmelt that flows over land surfaces (impervious surfaces like pavement) without infiltrating into the ground, picking up pollutants along the way & can be decreased by pervious surfaces (like grass or forest).
What is stormwater runoff?
a "natural bathtub", or drainage basin for rain and snow. These are not defined by city or town boundaries.
What is a watershed?
This type of GI uses plants to treat stormwater runoff
what is bioretention, rain gardens, bioswales ect?
The idea that cities experience higher temperatures than their surrounding rural areas because of things like fewer trees or dark pavement.
What is the Urban Heat Island Effect?
Unlike GREEN infrastructure ------ infrastructure is NOT designed to mimic natural systems and often takes the form of concrete and pipes
What is GREY infrastructure?
the process where water on the surface of the land, such as rainwater or melted snow, moves downwards into the soil and groundwater. This is reduced in areas with impermeable surfaces.
What is infiltration?
The number of cities and towns OR the number of residents in the Charles River Watershed
What is 35 towns, OR 1 million+
Harvested rain water can be used for watering a garden, or washing a car, but NOT this.
What is drinking?
the combined process of evaporation and transpiration, where water is transferred from the land to the atmosphere?
What is evapotranspiration?
Bioswells, green roofs, and tree filters are all examples of this type of Green infrastructure
What is Bioretention
A CSO is discharge of wastewater, including both stormwater and untreated sewage, into nearby water bodies. What does CSO stand for?
What is a combined sewer overflow?
The most common bacterial threats to the Charles River Watershed are:
What is E.coli and/or cyanobacteria?
This type of GI needs an adequate separation distance from groundwater tables
What is permeable pavement or infiltration?
As part of our River Science program we test for what?
What is water quality, e coli, temperature, depth, cyanobacteria.
This type of GI is "A storage structure used to hold runoff for subsequent reuse; primarily for non-potable purposes."
What is rainwater harvesting?
This NUTRIENT is good for plants, but too much causes issues in our aquatic ecosystem.
What is Phosphorus?
The Charles River flows 80 miles from this town in, Mass. to the Boston Harbor.
What is Hopkinton?
This type of GI has a perforated pipe system to help distribute water evenly underground.
What is an infiltration basins or/ and an infiltration trenche?
The indiginous name for the Charles River
What is the “Quinobequin”?
