How do Green streets work?
How do Green streets work?
A green street is a stormwater management approach that incorporates vegetation (perennials, shrubs, trees), soil, and engineered systems (e.g., permeable pavements) to slow, filter, and cleanse stormwater runoff from impervious surfaces (e.g., streets, sidewalks).
What is green streets case study mainly focused on?
This case study describes the community’s “Green Streets” which are designed to allow rain water to percolate into the ground and return to the aquifer. These streets feature what is believed to be the biggest residential application of porous asphalt in the country.
Are street trees green infrastructure?
Municipal street trees are trees in the public right-of-way and are a key part of public green infrastructure in many cities. Street trees provide benefits that promote sustainability and help alleviate environmental problems.
What is complete street policy?
Complete Streets are streets designed and operated to enable safe use and support mobility for all users. Those include people of all ages and abilities, regardless of whether they are travelling as drivers, pedestrians, bicyclists, or public transportation riders.
What are green streets and alleys?
Green streets and alleys are created by integrating green infrastructure elements into their design to store and filter stormwater. Permeable pavement, bioswales, planter boxes, and trees are among the elements that can be woven into street or alley design.
Why is Permeable pavement important?
Permeable pavements help reestablish a more natural hydrologic balance and reduce runoff volume by trapping and slowly releasing precipitation into the ground instead of allowing it to flow into storm drains and out to receiving waters as effluent.
What is a tree trench?
Tree trenches and tree boxes are vegetated engineered landscape practices designed to filter or infiltrate stormwater runoff. They can be incorporated into a wide variety of landscaped areas, including ultra-urban landscapes.
How does Urban Forestry relate to green infrastructure?
The urban forest as green infrastructure, a primer A robust urban forest produces myriad environmental, economic, social and cultural benefits, all while bolstering urban identity in ways no other infrastructure type can.
What is green pavement?
Green pavement, a relatively new concept in green building, is a permeable and porous pavement (try saying that three times fast) that absorbs rainwater instead of repelling it. It allows water to return to the ground, which means the water doesn’t wash into the sewer, along with oil, gas and pesticide residue.
What counts as a permeable driveway?
There are three main types of solution to creating a permeable driveway: Using gravel or a mainly green, vegetated area. Directing water from an impermeable surface to a border rain garden or soakaway. Using permeable block paving, porous asphalt or concrete.
Where can I find the technical standards for Green Streets?
Technical standards, including drawings, specifications, maintenance schedule, and plant list, can be found in the Green Street Standards document. CHAPTER 4Implementing Green Streets
What are the different types of Green Street practices?
Stormwater curb extensions, stormwater planters and bioswales use the principles of bioretention but include unique design features and are described as different green street practices in this guidebook. Site Considerations Bioretention has a significant advantage over other practices because it can vary in size, shape and placement.
When should I incorporate Green Street elements?
Incorporating green street elements should be considered when the overall design of the street is being changed or utilities are being installed or upgraded. Chapter 3 discusses how to select appropriate green infrastructure practices.
What should be used for Green Streets applications?
Low water use, drought tolerant, native plants should be used for Green Streets applications. The use of reclaimed water is recommended to reduce the amount of potable water used for irrigation. www.sandiegocounty.gov/stormwater K-49 Effective January 1, 2019 2.5 T YPES OF P
