Projects in Seattle

Seattle Justice Center Green Roof

Justice Center Green Roof with the additional ability to look down on the City Hall Green Roof below. As some of the older roofs in the City, the Justice Center Green Roof was completed in October 2002 and the City Hall completed in July of 2003. Designed by SvR Design: The support system is from American Hydrotech and consists of a 6″ profile inclu-ding insulation, an “egg crate” style drainage/moisture retention layer and a custom soil mix over a multi-layered waterproofing membrane. The planting design by SvR was guided by an image of sunlight reflected in a shallow streambed, much like that of the water feature connecting the Justice Center with the City Hall. The pattern shows through in wavy swaths of greens, blues, and grays.

Ballard Rain GardensThe Ballard Rain Gardens were mentioned ne-gative by different authors on the internet. Thefollowing text is a reduced version of an articlefrom April 2011 by Lisa Stiffler.We will see how things have changed when weget there...

When Seattle was planning its first extreme-green makeover of a city block, residents com-peted for the honor. And in 1999, the winning street in Broadview got a facelift complete with new sidewalks and verdant roadside rain gardens with shrubs and grasses.But the rain gardens installed by the city last summer and fall haven’t worked as planned.Instead of solving problems, they have created

http://www.seattlepi.com/local/environment/article/Ballard-s-rain-gardens-A-bad-green-experi-ment-1345766.php

new ones. The gardens, which look sort of like shallow, sparsely planted ditches running between the road and sidewalk, fill with water – and stay filled. Some of the rain gardens drain over the course of hours or days, but some become miniponds until the city comes to pump them out. Now the financially pressed city will have to spend $500,000 to fix the rain gardens. And after the fixes, the gardens will do less of what they were designed to do: keep runoff from sewers to prevent overflows.Many of the residents are not pleased. They worry that the swamped gardens are a drowning hazard for young children, a breeding ground for mosquitoes and a flaw that will lower property values. “We feel badly,” said Nancy Ahern, deputy director for utility-systems management for Seattle Public Utilities, the department that installed the rain gardens. “It’s been hard on this community.”

From Wikipedia, the free encyclopediaLocation: Salmon Bay, Seattle, WashingtonBuilt: 1906Architect: MultipleGoverning body: Army Corps of Engineers

The Hiram M. Chittenden Locks is a complex of locks that sits at the west end of Salmon Bay, part of Seattle‘s Lake Washington Ship Canal. They are known locally as the Ballard Locks after the neighborhood to the north.

The locks and associated facilities serve three purposes:To maintain the water level of the fresh water Lake Washington and Lake Union 1.at 20–22 feet (6.1–6.7 m) above sea level (Puget Sound‘s mean low tide).To prevent the mixing of sea water from Puget Sound with the fresh water of the 2.lakes (saltwater intrusion).To move boats from the water level of the lakes to the water level of Puget 3.Sound, and vice versa.

The complex includes two locks, 30 ft × 150 ft (9.1 m × 46 m) (small) and 80 ft × 825 ft (24 m × 251 m) (large). The complex also includes a 235 ft (72 m) spillway with six 32 ft × 12 ft (9.8 m × 3.7 m) gates to assist in water-level control.A fish ladder is inte-grated into the locks for migration of anadromous fish, notably salmon.

The fish ladder at the Chittenden locks is unusual in being located where salt and fresh water meet. When the Corps of Engineers first built the locks and dam, they changed the natural drainage route of Lake Washington. The locks and dam blocked all salmon runs out of the Cedar River watershed. To correct this problem, the Corps built a fish ladder as the locks were constructed to allow salmon to pass around the locks and dam.The ladder was designed to use attraction water: fresh water flowing swiftly

Chittenden Locks and Salmon Passageout the bottom of the fish ladder, in the direction opposite which anadro-mous fish migrate at the end of their lives. However, the attraction water from this first ladder was not effective. Instead, most salmon used the locks. This made them an easy target for predators; also, many were injured by hitting the walls.

The Corps rebuilt the fish ladder in 1976 by increasing the flow of attraction water and adding more weirs: most weirs are now one foot higher than the previous one. The old fish ladder had only 10 „steps“; the new one has 21. A diffuser well mixes salt water gradually into the last 10 weirs. As a part of the rebuilding, the Corps also added an underground chamber with a viewing gallery.

Libraries are traditionally stark repositories of knowledge. Installing a green roof was an opportunity to generate commu-

nity interest in green design to make this facility a dynamic teach-ing tool for sustainable design and environmental awareness.

The green roof was incorporated as part of an overall strategy to reduce and conserve energy costs where possible. Solar

(photovoltaic) panels provided by the Seattle City Light Green Power Panel installed on the northern edge of the roof will monitor the amount of electricity captured and collected onsite. Energy generated from these panels is fed back in to the city’s power grid, reducing the Library’s energy bills. Additionally, various rooftop sensors measure wind speed, direction, sunlight, etc.

The gently curving roof is visible from the periscope and obser-he gently curving roof is visible from the periscope and obser-he gently curving roof is visible from the periscope and observation deck and invites visitors to engage in the green roof’s Tvation deck and invites visitors to engage in the green roof’s T

ecology above the street. The project illustrates green building is feasible within a modest budget, presenting the community with an ideal example of benefits realized when sustainable design combines with extraordinary architecture.

As the site is in an urban setting, the challenge was to develop the site in a restorative manner. Formerly home to a bank

and a parking lot, hardscape comprised 100% of the lot cover-and a parking lot, hardscape comprised 100% of the lot cover-and a parking lot, hardscape comprised 100% of the lot coverage. Today, combined with the green roof and planters at the building perimeter, the hardscape has been reduced to 20% of the lot coverage.

The seamless waterproofing membrane used for the green roof project, Monolithic Membrane 6125®EV-FR (fabric

reinforced, environmental grade, 25% recycled content), is a hot fluid-applied, rubberized asphalt that forms a long-lasting, tena-cious bond to the substrate. MM6125EV-FR’s unique formulation, which includes inert clay fillers, provides excellent resistance to acids and fertilizers.

SEA StreetsStreet Edge Alternatives (SEA Streets) ProjectSeattle, WA (2001)

Background: Seattle Public Utilities constructed a drainage project at 2nd AvenueNW known as a Street Edge Alternatives (SEA Streets) project. It involved the complete reconstruction of the street and its drainage system to reduce impervious area and install stormwater detention ponds. It was completed in the spring of 2001, and designed to provide drainage that more closely mimics the natural landscape prior to development than traditional piped systems. To accomplish this, Seattle reduced impervious surfaces to 11 percent less than a traditional street, provided surface detention in swales, and added over 100 evergreen trees and 1100 shrubs.

The method they used to achieve this goal was to maximize the stormwater time of concentration and the sites detention volume, without compromising homeowner access and parking needs on the street. They also sized the swales to detain the pre-developed two-year, 24-hr storm event, while not allowing infiltration. Finally, they hydraulically connected the swales into three groups, with each group controlled by a flow control structure. Detention volume achieved by the swales was 2,500 cubic feet; 37% more volume than would have been required by their drainage ordinance.

Monitoring: Two years of monitoring show that the SEA Streets project has prevented the discharge of all dry season flow and 98 percent of the wet season runoff. Whereas all events in the baseline monitoring period, which occurred mostly in the dry season, created a discharge.

Conclusions: One of the primary drainage goals was to use surface retention or detention to reduce 2-year, 24-hour storm event (1.68-inches) peak runoff rate and volume to pre-developed conditions. The SEA Street design resulted in reduced total volume of stormwater within its 2.3-acre capture area by 97 percent for two consecutive years. This significantly reduced the impacts of urban environments on streams inhabited by salmon. The SEA Streets design fully attenuates 2300 ft3 (65.2 m3) of runoff, which represents the volume produced by approximately 0.75 inch (19 mm) of rain on its catchment. Mean storm quantity at Seattle-Tacoma International Airport is 0.48 inch.

The project exceeds Seattle’s stated goals, but falls short of the Healthy Waters Aspirational Goal. Also the site was designed to only detain a large portion of a storm’s flow and not retain it. It captured up to 97% of runoff from all storm events within a 2 year period. That is different, and less stringent, than capturing 97% of the runoff from all storms and retaining that volume onsite. Also, water quality was not monitored. It was assumed flow reductions would reduce contaminant loads, but no data exists to quantify any reductions. Since the bulk of the storm eventually leaves the site anyway, reductions of contaminant levels would not likely be impressive.

High Point

Because of its size and its relationship to Longfellow Creek, the redevelopment of the High Point neighborhood in West Seattle offered Seattle Public Utilities (SPU) a unique opportunity to implement a large scale natural drainage system in an urban environment, where it could make a real difference. High Point features the largest natural drainage project that the City has undertaken, and the first time that a natu-ral drainage strategy of this scale has been used in such a high density urban setting.Designed in partnership with Seattle Housing Authority, this natural drainage sys-tem will treat about 10 percent of the watershed feeding Longfellow Creek – one of Seattle’s priority watersheds.

The natural drainage system at High Point mimics nature in many ways by using features such as swales to capture and naturally filter storm water and open, lands-caped ponds or small wetland ponds to hold an overflow of storm water.The end results are nothing short of remarkable. When completed, High Point will process water in a manner similar to a forest meadow.High Point serves as an exemplary model for other large-scale developments, both locally and across the country. And SPU will continue to look for even more innovati-ve ways to promote and encourage responsible stewardship of the environment – in Seattle and across the country.

The High Point NDS is part of the High Point Redevelopment, which covers 34 blocks - from 35th Ave SW to High Point Drive SW and SW Juneau St. to SW Myrtle St.

Construction of the first phase of the High Point NDS was completed in the fall of 2005. The first phase is bounded on the north and south by SW Juneau St. and SW Morgan St., and on the west and east by 35th Ave SW and High Point Drive SW. The second phase of construction was completed in 2009.

SPU began monitoring the first phase of the High Point natural drainage system in January of 2007.

Thornton Creek

Thornton Creek Water Quality ChannelSeattle, WA

By working together, an engaged City and Northgate community helped sha-pe the innovative project called the Thornton Creek Water Quality Channel. The result is a 2.7-acre public amenity and water quality facility, located just south of Northgate Mall in Seattle, adjacent to the I-5 corridor. As landscape architects and civil engineers, SvR designed the channel to treat runoff gene-rated from 680 acres during small, high-frequency storms.

The channel provides habitat and functions as a bioswale, mimicking the structure of a natural stream bed and riparian zone with a central base flow channel and densely vegetated banks. The site provides water quality treat-ment and accommodates seasonal high flows. Channel highlights include:

A series of cascading weirs, pools, boulders, and large woody debris•Large-scale natural drainage treatment in a public setting•Integration into mixed-use development by providing public open space•Targeting up to 91% average annual runoff for water quality treatment•Plant mix includes a blend of 18-inch to 36-inch tall reeds, rushes, sedges, •and shrubs to provide year-round flow resistance and contribute to urban habitat and biodiversity

The water for treatment comes from Interstate 5, Washington’s busiest free-way, as well as the North Seattle Community College campus, Seattle’s north end public transit hub, nearby arterial streets, and the Northgate Mall.

The Madison Valley drainage system was built in the early 1970s and was designed to handle only a 25-year storm. In December 2006, a 100- or 150-year storm event created a surge of water, mud and debris that clogged storm drains and claimed the life of a valley resident, trapped in her basement by fl oodwaters.fl oodwaters.fl

“There were 3 million gallons of water and only 1 million gallons of storage,” SPU project manager Brent Middleswart was quoted in 2009. “This whole project is about raising the level of protection to deal with the capacity of another extreme storm event.” Phase 1 expands the surface facility to provide 1.8 million gallons of storage; Phase 2 extends a 48-inch north to Washington Park, and constructs an additional 2.2 million gallons of surface and underground stormwater storage.

Dubbed by concerned neighbors as the “Pit”, a series of emotional meetings with the community produced a design for the Phase 1 site that improves the detention basin spaces to make them a neighborhood natural amenity while maximizing the site’s storm water storage function. The design provides a curvilinear, accessible path from the southwest through the basin, atop a rock gabion bridge that crosses a (usually) dry creek bed to an overlook and a direct route up the east bank. There is an informal route that follows the creek bed connecting the north and south access points. The southwest corner entry provides a water feature stone and sand area for small children, tables and broad playful stone steps into the rolling lawn terraces providing amphitheatre seating which wrap the basin to capture sunlight.

The landscape is a microcosm of the valley restored, with all native plantings, local stone, and an intermittent creek fl ow. The plant selections were carefully tailored to the dry/wet conditions, fl ow. The plant selections were carefully tailored to the dry/wet conditions, fland reviewed per SPU sustainable landscape maintenance practices.

Headwaters at Tryon Creek

The Headwaters at Tryon Creek serves as a demonstration in sustainable stormwater management, green development practices, wildlife habitat restoration and water conservation. The development includes LEED Silver rated senior housing, town homes and market-rate apartments along with numerous environmental site enhancements which are highlighted by the first daylighted creek in the City, running the length of the 2.8 acre (1.1 hectare) property. This newly developed community is now a part of the growing ecology of its site.

• Variety of Housing – Senior, Affordable Row Houses, and Market Rate Apartments

• Building Construction – Complete in 2006 • Wetland Enhancement – Complete in 2006

– enhancement of upstream wetland adjacent to project • Rain Garden – Complete in 2008

– manages 1.5 acre (0.6 hectare) of commercial parking lot and street runoff Special features of the site include:

The daylighted tributary stream of Tryon Creek:

• originally ran through a pipe under the site

• is approximately 450 linear feet (135 meters)

• connects an upstream, forested wetland to a downstream rain garden

• is planted with native trees, shrubs, and grasses that restore lost riparian and wetland habitat

• has a 5 foot (1.5 meter) deep gravel lens below the stream bed that helps direct flow below the surface for groundwater recharge.

The Rain Garden:

• covers 0.5-acres (0.2-hectares)

• sits on the site of a former traffic triangle and a 200 foot (61 meter) section of street

• allows the long-buried stream to connect with Tryon Creek

• treats storm water from adjacent development and right-of-way, helping to filter pollutants as well as reducing the rate and magnitude of stormwater flows.

Sights in PortlandRemaining elements of the site continue to celebrate water while endeavoring to mimic natural processes. These include:

• green street infiltration planters that artfully display the conveyance of stormwater, collecting onsite stormwater as well as stormwater from the public right of way.

• flow-through planters adjacent to the building capture roof runoff, and individual downspout gardens diffuse and infiltrate the stormwater.

• a 14,000 square foot (1,300 square meter) ecoroof and captures and detains precipitation and provides supportive habitat to the area.

• pervious pavement was used in the parking lots.

While excavating the site, soil contaminants including cleaning fluids and gasoline were discovered; over 2,200 tons (2,000 metric tons) of contaminated soil were removed from the property and replaced with clean soil and gravel.

Partnerships included: The City of Portland Bureau of Environmental Services (BES), Portland Development Commission (PDC), Housing Authority of Portland (HAP), Bureau of Parks and Recreation (Parks), and Portland Department of Transportation (PDOT), Office of Sustainable Development, METRO, Oregon Watershed Enhancement Board, and US Fish and Wildlife Services.

Grant funding was provided for stream restoration from the Oregon Watershed Enhancement Board, Community Incentive Fund, and Metro’s Greenspaces Program.

Mt Tabor Middle SchoolBES Design Report Stormwater Retrofit at Mt. Tabor Middle School

5800 SE Ash Street, Portland, Oregon

Project SummaryProject Type A school retrofit to protect nearby residents from surcharging of the combined sewer Technologies A variety of vegetated infiltration facilities and drywells Benefits The facilities capture runoff from about two acres of roof, parking lot, play area, and street.

They infiltrate most of the captured flow, helping reduce combined sewer overflows (CSOs). They are attractive additions to the school grounds, help shade and cool the south side of

the building, and provide an educational resource for students. Notable Features

The project showcases a range of applications for vegetated facilities that create a greener, healthier environment for the students and staff at the school.

The rain garden received a 2007 Design Award from the American Society of Landscape Architects (ASLA).

Cost The fully loaded cost of construction was $523,000. Construction City-hired contractors constructed the project in phases during 2005, 2006, and 2007. Ownership Portland Public Schools owns the facilities.

Introduction

The school from the west, prior to the project. The site has about 4 acres of impervious area, of which about 2 acres

drained to the sewer at SE 57th & Pine ( )

The "rain garden" after a storm event ; the reflection ofstanding water is visible.

In 2002, the Bureau of Environmental Services (BES) began planning for a project to protect residents from sewer backups on SE Pine Street adjacent to Mt. Tabor Middle School1. The combined sewer on Pine Street periodically surcharged during extreme rain events, pushing runoff mixed with sewage into some residents’ basements. As an alternative to replacing the sewer lines, which were in relatively good condition, the Bureau approached Portland Public Schools (PPS) with a plan to retrofit the school with stormwater infiltration facilities. Preliminary estimates showed the project would be cost-effective compared with replacing the sewer lines.

The plan included a number of vegetated infiltration facilities and drywells around the perimeter of the building. The concept built on the experience of the two organizations at nearby Glencoe Elementary School. Collaborating with the school district, BES constructed a related project there in 20032. The project at Tabor Middle School presented a number of new challenges including the large scale of the undertaking; a fairly comprehensive retrofitting of the site was required to protect residents from sewer backups.

1 See BES engineering predesign report for the Sullivan, Stark, and Holladay Basins, October 2002.

12 BES constructed a large infiltration basin at Glencoe to protect residents on SE 52nd from sewer backups.

BES and PPS agreed that the project presented a unique opportunity to showcase a range of facility types suitable for different retrofit settings. The partners made it a priority to seek the multiple benefits that well- designed vegetated facilities can provide: aesthetic improvements, shade and cooling for the south-facing classrooms, educational benefits for the students, and general environmental improvement.

Facilities with Catchment Areas

BES staff designed the project in collaboration with PPS. City-hired contractors constructed the main components during the summers of 2006 and 2007. The project included a “rain garden” (large planter), a vegetated swale, six smaller infiltration planters, and three drywells. BES also constructed a stormwater curb extension and sump adjacent to the school at SE 57th and Pine Street. The facilities together manage runoff from approximately two acres of roof, playground, parking lot, and street surface.

Prior to construction, looking north across the parking lot toward the site of the rain garden. The parking lot swale was constructed between the rows of parking

stalls in the forerground.

Stormwater Management Goals

1

2

3 3 3 3

34

5

The primary goal was to protect nearby residents from sewer backups by managing enough runoff to reduce and delay the peak of the BES design storm3. That goal required managing runoff from about two acres of impervious surface and creating at least enough internal capacity (volume) in the facilities to capture and infiltrate the peak of the city’s design storm for sewer backups. It was a major secondary goal to test and demonstrate how vegetated facilities can be integrated into school sites.

Geotechnical Evaluation

NRCS soil classificationThe Natural Resources Conservation Service classifies the surface soils at the school as Urban/Latourell Complex, a silty loam with a pass rate of 70-80% for the #200 sieve. Permeability is characterized as moderate, with a range of .6 - 2 inches per hour.

3 The design storm has a recurrence interval of 25 years. The intensity is highest during the first 5 minutes (equivalent to 3.32 in/hr) and tapers from that point. Facilities with enough internal volume to capture the first 15 minutes of the storm, prior to overflowing, should be large enough to help protect against sewer backups in that storm.

SE 45th and Clay – Tabor to the River Green Streets

The Tabor to the River project area extends over 2.3 square miles and integrates hundreds of green streets, tree plantings and pipe upgrades. These improvements will improve sewer system reliability, stop sewer backups in basements and street flooding, control combined sewer overflows (CSOs) to the Willamette River, and restore watershed health. More than 500 Green Streets will be constructed, saving the city an estimated $58 million in avoided pipe-only upgrades. The Tabor to the River project is a partnership between the city and the community to create sustainable solutions to urban watershed problems. The result will be a sound, dependable sewer and stormwater infrastructure, more livable neighbor-hoods, and cleaner rivers and streams.

The constructed wetland pilot project is located adjacent to the wastewater treat-ment facility in the town of Discovery Bay a community of about 13,500 people. Wetlands are of interest to this utility as designed treatment wetlands (DTWs). DTWs designed to optimize one or more of the foregoing treatment mechanisms for specific wastewater treatment purposes. As an example, a DTW may be designed to remove one or more classes of water contaminants: organics, nitrogen compounds, pathogens, metals, refractory organics, colloids, etc.

In 2007, Discovery Bay implemented a DTW demonstration project to remove metals, specifically copper, utilizing the expertise of Alex Horne Associates (DTW specialists) and the University of California, Berkeley (Prof. David Sedlak). The result was four pilot-scale DTWs designed to remove metals, and a fifth experimental POP (Phyto-chemically enhanced Oxidative Photo degradation) cell designed to remove pharmaceuticals. This research continues today under the ReNUWIt Natural Systems Thrust looking at pathogen removal and de-nitrification.

We will hear from, the City Utility Manager of Discovery Bay, Alex Horne, Professor Emeritus at UC Berkeley and luminary in natural systems and several PHDs working on various projects on the nutrient removal and other treatment properties of the wetland. We will tour the wastewater plant and the surrounding wetlands. More Bios to follow.

Jeg gennem mit virke som ingeniør og planlægger på afløbsområdet i Nordvand har behov for øget kendskab til løsninger omkring håndtering af regnvand i byerne. Gentofte og Gladsaxe Kommuner som Nordvand dækker er to fuldudbyggede kommuner, hvilket giver en række udfordringer i forhold til at håndtere fremtidens øgede regnmængder på en økonomisk og miljømæssig optimal måde. I Nordvands opland er der krav om at alt regnvand skal være separeret fra i løbet af ca. 50 år, og anlægsarbejdet er i fuld gang. Da Nordvand i større dele af området ikke har havet som umiddelbart recipient, er deltagelse i Vand i Byer oplagt for indsamling af nyeste viden om regnvandshåndteringsmetoder samt mulighed for sparring om aktuelle problemstillinger.

Jeg skal med på ViB ekskursion til USA, fordi:

Det virker til at man i USA er længere fremme med etablering af anlæg til lokal anvendelse af regnvand, og dermed måske også har flere erfaringer med snitflader mellem forsyninger, kommuner, borgere m.fl. samt erfaringer med stofkrav til rensning af regnvandet.

Hvilke forventninger har jeg til turen?

Inspiration til alternative lokale anvendelser af regnvandet samt indsamling af viden med tilladelser og krav til anlæggene. Inspiration til formidling og kommunikation at regnvandsprojekter til borgere, politikker og andre ikke nørder. Mulighed for at styrke mit netværk omkring håndtering af vand i byer.

Jeg arbejder i ViB med internationalisering og eksport og bruger min viden fra et parallelt arbejde i Danish Water Forum, hvor jeg er ansvarlig for innovation og eksport. Der kommer så mange interessante resultater fra ViB, så det ville være en skam, hvis vi ikke i fællesskab ser, om de kunne bruges i kommerciel sammenhæng og derved sprede dansk vandteknologi, ydelser og produkter til verden uden for DK.


Jeg forventer, at der sker udviklinger i USA, som vi som gruppe kan lære af, men der er også en god mulighed for, at vi måske kan lære USA noget.


Jeg ser turen som en rigtig mulighed for gode diskussioner blandt deltagerne og derfor også bedre muligheder for øget samarbejde efter turen.
