New York Water System
New York City's water supply system has grown from a few wells on Manhattan Island to one of America's most extensive municipal systems. Today, it relies on a combination of tunnels, aqueducts and 19 reservoirs both in the city and far upstate to meet the daily needs of 8 million residents and countless visitors. Thanks to well protected wilderness watersheds, New York's water treatment is simpler than in other American cities. Downhill flow allows the system to do without pumps.
The complex system is divided into three separate systems:
- The Croton system, the oldest and smallest, sits in Westchester and Putnam Counties.
- The Catskill system, built decades later, is significantly larger then the Croton. In the early years of the 20th century, the city and state designated thousands of acres in the eastern Catskills to build two reservoirs that more than doubled the city's capacity.
- In the 1950s and 1960s, the city expanded its water system again, tapping the east and west branches of the Delaware River, as well as other tributaries of the Delaware and Hudson rivers to create the newest and largest of its three systems, the Delaware system, which provides around half of the city's water supply.
The Croton system is the source of numerous turbidity issues for the city's water. Engineering studies in 1903 also recognized that the clay of the steeply sloped Eastern Catskills turned the clear waters of the Schoharie and Esopus Creeks (which feed the Catskill system) muddy after storms. In addition, both the Cannonsville reservoir of the Delaware system, as well as many reservoirs within the Croton system have also had quality issues related to algeal blooms.
The city has sought to restrict development throughout its watershed. One of its largest watershed protection programs is the Land Acquisition Program, under which the New York City Department of Environmental Protection has purchased or protected through conservation easement over 70,000 acres (280 km²) since 1997.[1]
World's 1st mobile water purification system debuts - April.26.2005
Jean-Michel Cousteau, explorer, educator, environmentalist and film producer, joined business executives yesterday, in New York, in launching the first water purification unit that converts polluted water into drinkable water.
The 12-meter-long mobile emergency filtration system, or MEFS, which was on display at a Manhattan pier in Chelsea,(pictured), took in large quantities of the Hudson River and converted the brown liquid into clear water during a process that took about 15 minutes, as reported by Kyodo News and published by Japan Today.
The unit, which is the first of its kind, is capable of producing 60,000 gallons of high-quality water per day and was created by Ecosphere Technologies, a subsidiary of UltraStrip Systems, Inc.
The self-contained unit could be installed on an emergency or temporary basis and would be capable of providing enough water for the daily needs of 10,000 people.
New York Water System: Reservoir Management


the water test:
Many New Yorkers say they drink bottled water because it tastes better, but ABC's 20/20 did a blind taste test.
They offered people New York City tap water and five other bottled waters, Evian, the top-selling bottled water Aquafina, Poland Spring, Iceland Spring (which comes all the way from Iceland), and American Fare, a discount brand from Kmart, which sells for less than half the price of Evian.
"In our test of bottled waters, Kmart's American Fare — the cheapest brand — won. Big-seller Aquafina came in second.
Iceland Spring tied the ordinary tap water for third place. Fifth place went to Poland Spring, and in last place, by far, with almost half the testers saying it tasted bad, was the most expensive water — the fancy French stuff, Evian.
"It tasted like toilet water," one man said.
Evian had no comment about that review.
Bottom line, if you buy bottled water because you think it's healthier than tap, test after test shows no evidence of that. And if you buy fancy brands because you think they taste better, you're probably just buying the hype. " ::ABC

LANDSCAPE: Greensburg, Kansas, GreenTown

Eleonore de Lusignan
After the tragic tornado storm that swept through Greensburg, Kansas on May 5th, 2007, the town is left to rebuild itself from scratch. So why not doing it right and making it the most sustainable in America? With the support of FEMA (Federal Emergency Management Agency) Greensburg has established a Long-Term Community Recovery Plan that as stated sustainability as there number one priority. The decision made along several town meetings, energy use was put on top of the list and the Department of Energy’s National Renewable Energy Laboratory has established a field office in the town.

There’s a constant tension between rebuilding as fast as possible and making the right decisions. But because Greensburg was already on a slow, steady decline prior to the tornado,” explained Hardy, “residents know that if they were to simply jump in and rebuild exactly as before, there’s no reason that trend would change. They recognize that and want to do something different.”
Greensburg-based companies are using the disaster as an opportunity to advance their businesses by embracing environmental responsibility.
"
TH: So what led to the desire of the townspeople to rebuild green?
BD: I think several things have contributed to it. Number one is that we’ve all been called to be good stewards of what the lord has blessed us with, and that’s just naturally going green because we’ve all become aware that the fossil fuel resources are running out. So we’ve lessened our use of fossil fuels and cut utility bills; sometimes without spending a tremendous amount of money by 30, 40, even 50 percent.
In rural America we are the original recyclers and our forefathers and pioneers knew the advantages of passive solar heat with their animals and homes, and geothermal energy as well, using it through dugouts and cellars with root crops. They were aware of all that technology generations ago. So that’s where we go back to as our roots; take care of the land because it takes care of you.
And being close to nature has also really spurred us on now that we’ve had the opportunity to rebuild from scratch. " Treehugger

WATER: Greywater Guerrillas

The Greywater Guerrillas are a collaborative group of educators, designers, builders, and artists who educate and empower people to build sustainable water culture and infrastructure.
According to the New York Times, they are "a team focused on promoting and installing clandestine plumbing systems that recycle gray water — the effluent of sinks, showers and washing machines — to flush toilets or irrigate gardens." with a mission: “It’s about trying to use resources to their full potential and interact with ecosystems in a beneficial way.”
http://www.nytimes.com/2007/05/31/garden/31greywater.html?pagewanted=1&_r=2

This is not just using a hose to spray your garden with shower water, this is a sophisticated recovery system. the picture above shows "A pipe running from the house deposits shower and sink water into an elevated bathtub in the yard that is filled with gravel and reeds, and the roots of plants begin filtering and absorbing contaminants. The water then flows into a second, lower, tub, also containing a reedbed, before flowing into a still-lower tub of floating water hyacinths and small fish."
recently published "Dam Nation: Dispatches from the Water Underground"
Dam Nation is a people's history of water—and the water grid; a detailed accounting of the fallout from a century of Manifest Destiny's attacks on wild rivers. The book traces how—across five continents—beleaguered commoners block the neoliberal makeover of the world and endeavor to restore balance between humans and watersheds. These strategists and innovators blow open the scarcity myth to show how local democratic control coupled with watershed restoration can provide water for everyone.

What is graywater ?
Any water that has been used in the home, except water from toilets, is called graywater . Dish, shower, sink, and laundry water comprise 50-80% of residential "waste" water. This may be reused for other purposes, especially landscape irrigation.
Why use graywater ?
It's a waste to irrigate with great quantities of drinking water when plants thrive on used water containing small bits of compost. Unlike a lot of ecological stopgap measures, graywater reuse is a part of the fundamental solution to many ecological problems and will probably remain essentially unchanged in the distant future. The benefits of graywater recycling include:
Lower fresh water use
Less strain on failing septic tank or treatment plant
Graywater treatment in topsoil is highly effective
Ability to build in areas unsuitable for conventional treatment
Less energy and chemical use
Groundwater recharge
Plant growth
Reclamation of otherwise wasted nutrients
Is graywater legal?
In practice, greywater legality is virtually never an issue for residential retrofit systems—everyone just bootlegs them. However, graywater legality is almost always an issue for permitted new construction and remodeling, unless you're in a visionary state such as
LANDSCAPE: New Chinese Cities, Bill McDonough + Partners

Leap frogging to future sustainable cities in China.
Eleonore de Lusignan
After the success of Bill McDonough's book Craddle to Craddle, China has implemented it into there government policy and McDonough's + Partners was given the responsibility to design 7 new cities with the expectancy that 400 million new Chinese citizens will need new homes within the next 12 years. For starts, Bill has begun designing two city plans: Guantang Chuangye Sustainable Conceptual Master Plan, and Tangye New Town Concept Master Plan.
"
Guantang Chuangye Sustainable Conceptual Master Plan
This concept master plan aspires to indicate, through design strategies, a future that is positive and hopeful in all aspects.

"Each of the demonstrations feature cradle to cradle design principles that are gaining recognition in part due to the recent Chinese printing of the book “Cradle to Cradle: Exploring Design for the Circular Economy” by William A. McDonough and Michael Braungart.
The sustainable design of urban centers is of vital importance to China and the world. In the coming two decades, 300-450 million people will move from the countryside to China’s cities. This year alone, China will build 5 billion square feet of new housing and consume 40% of the world’s production of cement. Over 65% of China’s cities are in a water shortage and 90% of urban watersheds are considered contaminated by Chinese government standards.
The China-US Center for Sustainable Development’s strategic goals are to set the standards for sustainable development and build the human and organizational capacity to achieve them. The Center’s mission is to accelerate sustainable development so that commerce, communities and nature can thrive and prosper in harmony – what China is now calling a “circular economy.” "

Tangye New Town Concept Master Plan
"Overview
This concept plan outlines a sustaining vision for a new administrative and cultural center for the government of the Licheng District in rapidly growing Eastern Industrial Zone east of
The plan develops a framework for achieving the ultimate goal of safe, healthy and delightful solar-powered cities. By considering issues beyond the initial use and operations of the development, the plan supports later adoption of emerging technologies and systems not readily available at the time of construction. For instance, proper orientation and solar access will enable the town to install photovoltaics should current trends continue make solar energy equal in cost to coal-fired electricity by 2016.
The pattern and organization of development responds to site-specific environmental features, systems, and flows. Vegetated fabric defines a patchwork of developable areas that imply a network of residential neighborhoods and commercial/public precincts. A series of linear parks running from east to west convey storm water to existing gullies and provide a setting for neighborhood amenities and a structure for pedestrian and bicycle routes throughout the new district. The plan also facilitates the integration of innovative infrastructure for water, wastewater, and energy production and use.

" Under the guidance and support of the China Housing Industry Association and the China-US Center for Sustainable Development, William McDonough + Partners with the support of WSP Environmental LLC was commissioned to create a concept master plan that embodies the principles of the Cradle-to-Cradle Design Protocol and sustainable design.
The concept plan aspires to indicate, through design strategies, a future that is positive and hopeful in all aspects; one that:
- Maximizes social engagement and community
- Creates an urban structure that promotes walking and healthy activities
- Effectively leverages the scarce land available for development
- Promotes alternative and renewable technologies
- Treats water as a precious resources
- Improves the quality of storm water leaving the site
- Uses biological resources to build and restore soil quality
- Restores habitat and biodiversity
- Learns from and respects the quality of the land and people"

The Ford Rouge project in
"In 1999 McDonough entered into an agreement with Ford Motor Company to redesign its 85-year-old, 1,212-acre Rouge River facility, an ambitious and innovative industrial/environmental makeover that will require 20 years--and $2 billion--to complete."
Overview by Will McDounough and Partners:
"This landscape master plan celebrates the potential to bring natural and industrial systems together to create a productive, regenerative landscape.
Henry Ford’s vision of linear production fundamentally reshaped the American manufacturing system --and provided a compelling framework for the transformation of this historic industrial site. Embracing Ford's heritage of innovation and business strength, the plan draws its inspiration from the features of the site and gives shape to the themes of linear production, historical legacy, and environmental regeneration. The large-scale interplay between the industrial and natural systems creates a new model for the regeneration of air, water, soil, and habitat through natural processes.
Devised for implementation over two decades, the design enables an orderly flow of people and delivery of materials through the site. A rectilinear pattern of hedgerows, swales, and trees reinforces the pre-existing street grid and creates a system that filters the millions of gallons of stormwater and reestablishes wildlife habitat.
The plan also reshapes
Additionally, the complex hosts groundbreaking research in phytoremediation. Researchers identified a dozen plants that successfully absorb and neutralize polycyclic aromatic hydrocarbons from the soil and established a 1.6-acre demonstration garden and research lab near the old coke oven by-products operations.

RadioHead cancel US concert to protest airplane carbon emissions
Radiohead go green for live show
Thom Yorke
Radiohead have decided not to travel to the US for a promotional performance because of concerns over global warming.
The Oxford five-piece are due to appear on a special edition of NBC's Late Night with Conan O'Brien.
The band opted to record a live version of House Of Cards in London rather than fly over to the US for the one-off performance.
Radiohead will appear on the show on Wednesday as part of NBC's Green Week.
Frontman Thom Yorke said the band avoided leaving a carbon footprint equivalent to driving a car for a solid year by recording the track in London.
Climate Change
RADIOHEAD GREEN FACTS
Radiohead always consider the carbon footprint when on tour
Thom Yorke's fears over climate change made him back the Big Ask campaign which urges ministers to bring in laws to reduce C02 emissions
He refused to discuss climate change with Tony Blair because he felt the fromer PM had "no environmental credentials"
The band have been long time campaigners on green issues with Yorke recently guest editing The Observer Magazine to promote climate change awareness.
Yorke also recently urged politicians to introduce sweeping measures to cut carbon emissions by 2020.
"If we don't get stuck in now, in 20 years' time it will be worse and things will be more extreme," he said.
The band kick-off their In Rainbows world tour with a show in West Palm Beach, Florida, on 5 May.

Water–Bottled Water
Mary Banas
Why bottled water? (or why not bottled water...)
• Bottled water bottles are made from oil, a limited resource. Just making the containers alone consumes more than 1.5 million barrels of oil annually, enough to fuel 100,000 cars for a year, according to the Earth Policy Institute. (Maybe we should get rid of the cars, but that’s a topic for another time.)
• It takes a lot of oil to transport bottled water from supposedly pristine springs all over the world to us. That bottle of Fiji water really does come from Fiji — and it doesn’t walk here by itself.
And all those trucks eventually clog our roads and double park in front of stores and offices to deliever their unneeded goods. But that’s just the production half of the equation, there’s the disposal too:
• Thirty million bottles end up in landfills every day — and considering that New York doesn’t have its own landfill anymore, we have to pay to dump our empty water bottles elsewhere.
• New York City tap water is safer and better than bottled water anyway. The Environmental Protection Agency’s standard for tap water, for example, is stiffer than the Food and Drug Administration’s standard for bottled water. Plus, our tap water tastes better than all those fancy waters (the Aquafina that’s bottled in Queens actually is New York City tap water — which is then distilled and reconfigured with Aquafina’s proprietary mix of minerals.)
How it works?
• The world spends $100 billion a year on bottled water at a time when the United Nations says that just $15 billion could double the number of people who have access to safe drinking water.
• And, rich people consume far more bottled water than poor people — so if tap water quality declines, it will fall to the politically less powerful to fight for cleaner water because the rich have turned their backs on the entire system.
What the individual can do:
1. At home, use a cup and fill it with tap water
2. On the go bring along a reusable hard plastic bottle and refill as necessary with tap water, remember to wash it periodically.
3. At the office, leave behind some mugs and cups that you can use there, again washing them periodically - the same applies to your morning coffee
4. If you end up having no choice and bottled is all there is available, save that bottle and reuse it later when you see a tap or a water fountain.
Benefits?
• less carbon
• utilizing resources close to home instead of depleting those half way around the world (like the island of fiiji)
The Pacific Island Countries also face critical water supply and contamination problems because of the inability of governments to maintain ageing water reticulation and treatment systems set up during the colonial period. Fiji has the largest water system in the Pacific Islands based on an economy of scale, but this is a legacy from when Fiji was a British colony. The system has deteriorated steadily since Fiji became independent and is now a major impediment to future tourism development. Between 1991 and 1995, for example, the amount of water lost through broken pipes, leaks, and clandestine connections increased from 36% to 43%
Implementation in other cities
City of NY---campaign to drink tap water
The City of New York is trying to persuade its people to give up bottled drinks and consume tap water instead to help protect the environment.
According to published reports, the city is pouring $700,000 of taxpayer money into ads promoting New York City water.
New York City boasts wonderfully clean water piped in from six huge reservoirs west of the Hudson in the Catskill mountains, as far as 125 miles from Manhattan. The city is currently running a huge campaign for New Yorkers to "Get Your Fill." But is New York water really that clean? ABC news' 20/20 took 5 bottles of national brands and a sample of New York water to be tested by a microbiologist. They found no difference between the samples.

Water-Tips to Green you Water

How to Green your Water
1. No drips
A dripping faucet can waste 20 gallons of water a day. A leaking toilet can use 90,000 gallons of water in a month. Get out the wrench and change the washers on your sinks and showers, or get new washerless faucets. Keeping your existing equipment well maintained is probably the easiest and cheapest way to start saving water.
2. Install new fixtures
New, low-volume or dual flush toilets, low-flow showerheads , water-efficient dishwashers and clothes washing machines can all save a great deal of water and money. Aerators on your faucets can significantly reduce water volume; water-saving showerheads can cut the volume of water used down to 1.2 gallons per minute or less, and some even have a “pause button” to let you stop the water while soaping up or shampooing. Our interns recently pointed out that “spending about $30 on low-flow showerheads and faucets is estimated to save 45 gallons of that 260 gallons of water [used in a typical household per day], almost 18% of your usage. Splurging on a low-flow toilet could save another 50-80 gallons of water a day. Together, those changes nearly cut in half the household's daily use, saving a considerable amount of water – and passing that savings on to your water bill, as well as your water heating bill.”
3. Cultivate good water habits
All the water that goes down the drain, clean or dirty, ends up mixing with raw sewage, getting contaminated, and meeting the same fate. Try to stay aware of this precious resource disappearing and turn off the water while brushing your teeth or shaving and always wash laundry and dishes with full loads. When washing dishes by hand, fill up the sink and turn off the water. Take shorter showers or, as the old joke goes, shower with a friend: Treehugger TV shows you how. To put things in perspective, take a quick look at your next water bill when it arrives. It probably won’t be costing you too much, but the average household consumes multiple thousands of gallons each month. See if you can make this number go down. If you’re the graphing type, go nuts.
4. Stay off the bottle
By many measures, bottled water is a scam. In most first-world countries, the tap water is provided by a government utility and is tested regularly. (You can look up your water in the National Tap Water Quality Database) Taste tests have shown that in many municipalities, tap water actually tastes better. Bottled water is not as well regulated and studies have shown that it is not even particularly pure. A four-year study of bottled water in the U.S. conducted by NRDC found that one-fifth of the 103 water products tested contained synthetic organic chemicals such as the neurotoxin xylene and the possible carcinogen and neurotoxin styrene. (Grist) Much bottled water doesn’t come from a “Artesian springs” and is just tap water anyhow. (Coca-Cola adds salt to its Dasani water to make it taste better, just like fast food.) Not only is it more expensive per gallon than gasoline, bottled water incurs a huge carbon footprint from its transportation, and the discarded bottles are a blight. It’s no wonder that some people even think it’s a sin. If you want to carry your water with you, get a bottle and fill it. (Look here for some advise on durable, non-toxic container options.) If your water at home tastes funny, try an activated charcoal or ceramic filter. Here is a comparison of home-use water filters from Grist.
5. Go beyond the lawn
Naturalize it using locally appropriate plants that are hardy and don’t need a lot of water. If you have to water, do it during the coolest part of the day or at night to minimize evaporation. Here is a useful calculator to figure out landscape water use. Xeriscaping is a method of landscaping that utilizes only native and low water plants. It is an especially appropriate approach for states like California and Arizona where people often plant lawns like they live in Florida despite living in the desert.
6. Harvest your rainwater
Put a rain barrel on your downspouts and use this water for irrigation. Rain cisterns come in all shapes and sizes ranging from larger underground systems to smaller, freestanding ones. Some even glow!
7. Harvest your greywater
Water that has been used at least once but is still clean enough for other jobs is called greywater. Water from sinks, showers, dishwashers, and clothes washers are the most common household examples. (Toilet water is often called “blackwater” and needs a different level of treatment before it can be reused.) Greywater can be recycled with practical plumbing systems like the Aqus, or with simple practices such as emptying the fish tank in the garden instead of the sink. The bottom line? One way or another, avoid putting water down the drain when you can use it for something else.
8. At the car wash
Car washes are often more efficient than home washing and treat their water rather than letting it straight into the sewer system. But check to make sure that they clean and recycle the water. Better yet, try the waterless car wash. If you live in Manchester, the Levenshulme Baptist Church is recycling water from its Baptistery pool for charity car washes http://www.treehugger.com/files/2006/08/baptismal_water.php .
9. Keep your eyes open
Report broken pipes, open hydrants, and excessive waste. Don’t be shy about pointing out leaks to your friends and family members, either. They might have tuned out the dripping sound a long time ago.
10. Don’t spike the punch
Water sources have to be protected. In many closed loop systems like those in cities around the Great Lakes, waste water is returned to the Lake that fresh water comes out of. Don’t pour chemicals down drains, or flush drugs down toilets; it could come back in diluted form in your water.

Landscape- Urban Agriculture, Chicago Farm
City Farm: Chicago, Illinois
urban sprawl is eating up
farms as suburbs expand.
"Why not bring farms to the city?"




City Farm is a project of the
THERE ARE more than 80,000 vacant lots in
City farm started investigating whether intensive urban farming could provide enough income to support a house hold
"We found that by planning and planting carefully, you can create a job for an individual on about 10,000 square feet or about four lots,"
The anchor of the urban farming program is the center's static pile composting operation. The center contracts with bars, restaurants and grocery stores for food residuals; it has agreements with the Chicago Police Stables for its horse manure; and it accepts yard trimmings from landscapers - producing approximately 10,000 cubic yards/year of compost.
Another link that must be strong is the one between the farm and the community. An ideal situation, Dunn explains, has been established between a farmer and a school that has an adjacent plot of land. The farmer is allowed to use the land in exchange for teaching students about growing produce in a school gardening curriculum. "The nice thing about that situation is that one of the requirements of having an urban farm is having a relationship with the community and with the kids," says Dunn.
Four restaurants and three farmers markets currently purchase the produce. Contracts with restaurants are especially helpful because the fees are paid up front. On the other side, the chefs are paying for convenience and peace of mind. "We've discovered an attractive mix," Dunn notes. "Chefs don't have the time to purchase everything themselves or train a staff member what to look for. Our growers consistently produce the quality in appearance and taste that the chefs require and deliver it to the restaurant."

Trigger
1. Manage stormwater runoff both at the source and the surface.
2. Use plants and soil to slow, filter, cleanse, and infiltrate runoff.
3. Design facilities that aesthetically enhance the community.
Effect
* traffic calming

* reduces runoff volume
* cleans automobile drips of hydrocarbons and other pollutens (bioremediation)
* stores large volume of water
Managing stormwater runoff from the street through vegetated planters for flow and water quality benefit. A green street retrofit which manages stormwater at the source through a vegetated swale, while enhancing the neighborhood.
Stormwater Facility Science
The surface area of a typical stormwater facility allows runoff to pond and evaporate while sediments settle into a layer of mulch. The organic mulch layer prevents soil bed erosion and retains moisture for plant roots. It also provides a medium for biological growth and the decomposition or decay of organic matter. The soil stores water and nutrients to support plant life. Worms and other soil organisms are very good at degrading organic pollutants, like petroleum-based compounds. They also help mix organic material, increase aeration,
and improve water infiltration and water holding capacity. Bacteria and other beneficial soil microbes process the majority of pollutants, including most of the nitrogen. The stiff structure of plants such as rushes and sedges slows water passage and traps sediments within the surface area of the facility.

Mt Tabor Middle School
This summer, the City will build stormwater management facilities at the school and on SE 57th Avenue just south of Pine Street. The project will feature a raingarden, infiltration planters, and a stormwater curb extension. Over the last year, Environmental Services has worked closely with Portland Public Schools and the Portland Office of Transportation to design these facilities. The new systems will dramatically reduce the amount of runoff draining to the sewer, and reduce the risk of sewer backups in homes on Pine Street. These attractive facilities
are designed to improve the school grounds and the urban environment, in addition to managing runoff.
SW Hillsdale
Construction is completed on two water quality planters in downtown Hillsdale in southwest Portland. The planters will treat stormwater runoff from 20,000 square feet of SW Capitol Highway. Runoff will enter the planters through curb openings and filter through soil to remove pollutants. The filtered water will flow into a storm sewer that drains to Fanno Creek. Each planter will have shrubs to improve their appearance, provide root structure to help maintain soil infiltration, and create habitat for soil organisms that help break down pollutants. The City will evaluate these planters, along with another design installed at New Columbia in north Portland, for potential use at other locations.
SW Texas
This summer, the City will build stormwater facilities along SW Texas Street to treat, detain and dispose of drainage from 17-acres bounded by SW California Street, SW Nevada Court, SW Capitol Highway, and SW 26th Avenue. The project will consist of a combination of conventional
stormwater conveyance systems and stormwater swales to manage runoff from roofs, driveways, and streets.
This project is the City’s response to a citizen-led initiative. This flexible, innovative project meets the needs of the neighborhood,helps meet regulatory requirements, and improves quality of life. The completed green street improvements will direct runoff away from homes and backyards, alleviate basement flooding, and reduce street erosion. The project will also protect
the City’s sewer infrastructure by managing stormwater that contributed to problems downstream in the Burlingame sewer.
NE Fremont and 131st Place
This project is the first in Portland to manage street runoff and accommodate a ramp crossing for pedestrian safety. The City removed 400 square feet of asphalt on either side of the pedestrian ramp and installed a variety of plants. Stormwater enters the vegetated area on the
west side through a curb cut and flows under the ramp to the vegetated area on the east side. The soil and vegetation slow runoff flow, filter sediments and pollutants, and allow the stormwater to soak into the ground, which reduces the burden on the combined sewer system and recharges groundwater. This was a collaborative project between Environmental Services and the Portland Office of Transportation. The two bureaus will team up on future projects to manage stormwater runoff, protect pedestrians and increase neighborhood livability.
Housekeeping
Maintenance Policy Development
Because the number of Portland green streets is increasing, the City is drafting a formal green street maintenance policy to ensure facilities have long, productive lives and to let property owners and neighbors know what their responsibilities are. The main responsibility is simple maintenance. Neighbors and property owners should keep litter, brush and trees out of the green street facility, and shouldn’t stack or store anything in it. All other maintenance will be conducted by the City.
Owners would be responsible for items needed to maintain the facilities such as yard debris bags
and tools. The draft policy also recommends sending regular green street update letters or flyers to property owners and neighbors. The City wants to make sure that as new neighbors move in, they learn about their neighborhood green street and their maintenance responsibilities. We also want neighbors to know when city scheduled maintenance has occurred at a facility.
Testing
Gathering performance information on green streets and other stormwater management facilities is an important part of Portland’s Sustainable Stormwater Management Program. The City uses the information to determine which designs work best in specific locations to help plan and design new green street projects. So far, the City has tested the NE 35th and Siskiyou green street and the Glencoe Rain Garden. Tests at NE 35th and Siskiyou show the facility
cuts peak stormwater flows to the sewer system by an average 85% and that it captures and infiltrates all the stormwater during most rain events. The test shows the facility is effectively doing what it was designed to do, reduce residential basement flooding.
The City built the Glencoe Rain Garden at SE 51st and Morrison in response to a severe basement sewer backup problem on a residential street. Stormwater runoff from 35,000 square feet of asphalt flows into the rain garden. The facility captures all the runoff from small rain events and it reduces peak flows by an average 80%. Tests on green streets at SE 56th and Ankeny and SW 12th and Montgomery showed both facilities are meeting expectations. The tests also indicated the need for some simple design modifications to make the facilities more effective. This spring, the City will do more tests including the stormwater curb extension
at NE 131st and Fremont.

Landscape- Sustainable South Bronx: Green Roofs

Green Roofs:
A green roof system is an extension of the existing roof which involves a high quality water proofing and root repellent system, a drainage system, filter cloth, a lightweight growing medium and plants.
"Heat Island Effect":

Benefits:
Temperature Reduction and Energy Conservation:
Reduced cooling costs by keeping the heat off the building and increasing the amount of insulation. Improved longevity for the roof by minimizing wide temperature fluctuations and exposure to the elements.
Stormwater Management:

Green Roofs provide a way to prevent overflows by absorbing and holding onto the majority of water that falls on them during a typical rain. This water is then slowly released from the soil and into the atmosphere through the foliage – in a process called transevaporation.
Improved Air Quaility:
The amount of Oxygen produced by one tree with a 16 foot diameter canopy is equaled by the amount of Oxygen produced by a 16 square feet patch of green roof with 15 in. high foliage.
In NYC, it costs over $1000 to plant a small tree that takes years to grow that big, but it costs far less to build 16 square feet of green roofs today.
Vegetative surfaces also trap harmful airborne particulates and keep them from entering our lungs, and can dampen noise pollution too. Pollutants in the air are less harmful under lower temperatures that these roofs maintain.
Cost:
Retrofitting and existing building with a green roof costs more than a conventional roof, but this investment yields cost savings over time through energy conservation and rooftop longevity. A green roof can also increase the resale or rental value of a property, as well as provide aesthetic enjoyment for you in the meantime.
