Riversmart Washington
RiverSmart Washington What is RiverSmart Washington? The RiverSmart Washington project will be installing practices to reduce stormwater volume runoff in two neighborhoods in northwest Washington. These practices include permeable paving in alleys, roads, and parking lanes, and rain gardens in tree areas and curb bumpouts. The stormwater flow will be monitored and measured to calculate the stormwater runoff reduction. Why RiverSmart? Stormwater runoff carries pollutants from roofs, roads, alleys, and parking lots in the District’s storm drain system and into the streams. The pollutants impair the health of small streams and contribute to problems in Rock Creek, the Potomac River, and the Chesapeake Bay. The significant volumes of water erode stream banks and create poor conditions for aquatic life. The U.S. Environmental Protection Agency has issued a Municipal Separated Storm Sewer System (MS4) Permit (http://ddoe.dc.gov/publication/npdes-permit) to the District that requires stormwater runoff volume reduction and retrofits to existing buildings and streets to reduce stormwater runoff. The city is using green infrastructure and low impact design (LID) practices, such as such as rain gardens, bioretention, stormwater bumpouts, and permeable paving, to capture and filter the stormwater runoff. DC Water is exploring ways to use LID to reduce the stormwater flow into the Combined Sewer System (CSS) area to potentially reduce the size of tunnels required for stormwater storage under the Long Term Control Plan. Project locations Lafayette site: blocks bounded by Patterson St, 32nd St, Rittenhouse St, and Broad Branch Rd NW in the MS4 area MacFarland site: Georgia Ave, Iowa Ave, and Allison St NW in the CSS area.

The placards remind people that storm drains flow untreated, directly into local streams and creeks. Ashland’s storm drains are NOT connected to the sewage treatment plant. By placing storm drain markers, you can take an active roll in preventing pollution in your neighborhood. Volunteers may also distribute door hangers, informing citizens about the proper disposal of chemicals that could harm wildlife and pollute waterways. Storm drain marking helps build community and mobilize grass roots environmental protection. Marking also helps educate your neighbors about the importance of watershed protection. If you are interested, you can become a neighborhood leader for your own Storm Drain Stomp event.

Permeable Interlocking Concrete Pavement
Permeable Interlocking Concrete Pavement Description Permeable interlocking concrete pavement (PICP) consists of manufactured concrete units that reduce stormwater runoff volume, rate and pollutants. The impervious units are designed with small openings between permeable joints. The openings typically comprise 5% to 15% of the paver surface area and are filled with highly permeable, small-sized aggregates. The joints allow stormwater to flow enter a crushed stone aggregate bedding layer and base that supports the pavers while providing storage and runoff treatment. PICPs are highly attractive, durable, easily repaired, require low maintenance, and can withstand heavy vehicle loads. Figure 1 shows Figure 1. PICP in Seattle’s High Point neighborhood significantly reduce the total amount of impervious surface and runoff. Photo installed pavers in a Seattle, courtesy of ICPI. Washington residential neighborhood. Applicability PICP can be used for municipal stormwater management programs and private development applications. The runoff volume and rate control, plus pollutant reductions allow municipalities to meet regulatory water quality criteria. Municipal initiatives such as Chicago’s Green Alley program, use PICP to reduce combined sewer overflows and minimize localized flooding by infiltrating and treating stormwater on site. Private development projects use PICP to meet post-construction stormwater quantity and quality requirements. Public and private investments in PICP can potentially reduce additional expenditures and land consumption for conventional collection, conveyance and detention stormwater infrastructure. PICP can replace traditional impervious pavement for most pedestrian and vehicular applications except high volume/high speed roadways. PICP has performed successfully in pedestrian walkways, sidewalks, driveways, parking lots, and low-volume roadways. The environmental benefits from PICP allow it to be incorporated into municipal green infrastructure programs and low impact development guidelines.

Allen County Storm Drain Marking Guide022510
The Allen County Surveyor’s Office has established a storm drain marking program to involve and educate the community of the harms of dumping pollutants down the storm drains. The following guidelines are provided to assist individuals, groups or organizations in planning, implementing, and preparing a successful storm drain marking event and to provide information on what citizens can do to prevent or reduce pollution that enters our waterways through storm drains. What is a Storm Drain? A storm drain is a network of underground pipes designed to control flooding by transporting stormwater from urban areas to a waterbody. The storm drain marking program involves marking storm drain inlets. The following are typical examples of storm inlets. What is Storm Drain Marking? Storm drain marking is labeling a storm drain inlet with a pre-printed marker, tile, sticker, or stencil that reads “ Dump No Waste - Drains to River ”, "Drains to Stream ”, or a similar written message that specifies the waterbody to which the storm drain inlet drains. Allen County has chosen a vinyl marker that comes in circular or rectangular form that is applied to the inlet with an adhesive or tie straps depending on the type of inlet being marked. Why Should We Mark Storm Drains? • Storm drain marking informs others about the street-to-river connection. Allen County 1 Storm Drain Marking Guide Surveyor’s Office • Many people may not realize that water flowing into storm drains or any material that is dumped or washes into the storm drains is not treated before it empties into a river, stream, or pond.

Permeable Pavement
Angela D. Alsobrooks County Executive Permeable Pavement Fact Sheet What is permeable pavement? When rainwater falls on conventional pavement, such as concrete, it accumulates and then flows across and off of this impervious surface as stormwater runoff. Permeable pavement allows stormwater to slowly seep through (infiltrate), reaching the soil and replenishing the groundwater below the surface. A variety of permeable pavement materials are available, such as interlocking pavers, porous asphalt, pervious concrete, and manufactured grass pavers. Interlocking pavers consist of precast blocks (primarily brick or concrete) that are aligned in such a way that water is able to pass between the voids between successive blocks. Grass pavers are a type of open-cell paver made of concrete or plastic, in which the cells are filled with soil and planted with turf, as shown in the photo. What are the benefits to property owners and communities? • Reduces stormwater runoff, localized flooding, and erosion. • Replenishes groundwater and improves water quality through natural filtration processes. • Grass pavers can improve site appearance by providing vegetation instead of pavement. • Permeable pavement reduces the amount of land needed for stormwater management. • May satisfy requirements for green space, allowing more development on a site. How can you determine if your property is suitable for permeable pavement? Permeable paving is most appropriate for pedestrian-only areas and for very low-volume, low-speed vehicle areas such as overflow parking areas, residential driveways, alleyways, and parking stalls. To determine the suitability of areas on you property: • Identify existing impervious surfaces or areas that you intend to pave. • Exclude surfaces that accumulate sediment and debris which would reduce the effectiveness of the system.

How Do Storm Drains Work?
How do Storm Drains Work? The storm drainage system helps prevent floods by diverting rainwater into nearby waterways. During rainstorms, water runs off of buildings, roads, and other hard surfaces, picking up trash and pollutants along the way. The water and pollutants flow into storm drains and through underground pipes directly into the nearest stream, pond or water reservoir. What About the Drains in My House? The drains in your house are part of a different system, the wastewater system. Dirty water from inside your home flows into underground pipes that are connected to a wastewater treatment plant. The water from your home is cleaned before it is released back into creeks and streams. Stormwater is Not Treated? That’s right! The storm drainage system carries rainwater directly to creeks, streams, ponds and reservoirs. That is why it’s important to keep trash, motor oil, pesticides, and other chemicals from entering the storm drain – everything that goes in comes out in our waterways. Polluted water is harmful to fish, wildlife, and humans. Stormwater Provides Drinking Water to Us and Others Downstream Never pour or dump anything down a storm drain Keep streets clean Dispose of trash properly Rake leaves and debris away from storm drains Apply lawn and garden chemicals sparingly and according to directions Call Wilmington’s Wastewater Treatment Plant (below) to report pollution problems All Water is Recycled The same water that existed on earth in the beginning is still here. It continually moves around, through and above our planet as water vapor, liquid, and ice. The water that comes from our faucets may have been drinking water for the first man and woman.
