  • 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.

  • Permeable Paving Report
    City of Royal Oak Department of Community Development 211 South Williams Street Royal Oak, MI 48067 Permeable Paving Report June 13, 2019 The Honorable Mayor Fournier and Members of the City Commission: Pursuant to the city commission’s request, staff has undertaken an analysis of permeable paving materials and their appropriateness for use in the City of Royal Oak. The report (Attachment 1) presents options for the expansion of acceptable driving surfaces in the city and compares the permeable infiltration system options that could be utilized to meet the requirements of the stormwater ordinance (Ch. 644) and future storm utility ordinance. Respectfully submitted, Timothy E. Thwing Director of Community Development Approved, Donald E. Johnson City Manager 1 Attachment Attachment 1 Pervious Paving Options Background On the instruction of the city commission and city manager’s office, the planning & engineering divisions have undertaken an analysis of pervious or permeable paving options and their stormwater management implications. The objective of this report is two-fold: 1) To present options for the expansion of acceptable parking surfaces in the City of Royal Oak; 2) To compare the permeable infiltration system options that could be utilized to meet the requirements of the stormwater ordinance (Ch. 644) and future storm utility ordinance. Pervious or permeable pavement is a collection of alternatives to traditional pavement that allow for the infiltration of rainwater or snowmelt on-site. These alternative materials include pervious asphalt or concrete, permeable interlocking pavers, plastic grids or reinforced turf.1 When used as part of a larger infiltration system, these materials can be used as an alternative to, or in conjunction with, other stormwater detention systems.

  • 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.

  • 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.

  • Design of Permeable Paving Subject to Traffic
    8th International Conferce on Concrete Block Paving, November 6-8, 2006 San Francisco, California USA DESIGN OF PERMEABLE PAVING SUBJECT TO TRAFFIC Dr. Brian Shackel Visiting Professor, School of Civil and Environmental Engineering, University of New South Wales, Sydney, Australia 2052, E-mail: [email protected] SUMMARY Permeable paving offers significant benefits over conventional pavements in terms of sustainability and environmental impact. Such pavements need to be designed not only to carry traffic but also to manage runoff, infiltration and pollutant transport. They, therefore, present new technical problems and challenges to pavement designers that are not covered by conventional pavement design methods. In particular the selection, specification and characterisation of the materials used in the surface, base and sub-base of permeable pavements require designers to modify existing design methodologies to facilitate water movement through the pavements whilst maintaining satisfactory serviceability under traffic in saturated conditions. The concepts of permeable pavement design are outlined and the need to integrate with Water Sensitive Urban Design principles is emphasised. Progress in the characterisation and development of permeable pavement materials is described and current design data are assessed. The use of such data in the design of permeable pavements is then discussed. 1. INTRODUCTION In urban catchments, road surfaces can account for about 20% to 25% of impermeable surfaces i.e. roads are a major generator of runoff. The control of this runoff is the prime objective in Water Sensitive Urban Design, WSUD (Argue, 2004) or its British equivalent SUDS (Pratt, 2001; Interpave, 2004). One way to achieve this is to use Permeable Interlocking Concrete Paving (PICP).

  • Permeable Paver Maintenance Guide
    PERMEABLE PAVER MAINTENANCE GUIDE 1 This guide is specific to Unilock® permeable pavers as a maintainable system for storm water runoff and does not cover cleaning concrete pavers themselves. Please see the Unilock Product Care and Maintenance Guide (available for download at www.unilock. com) for information on cleaning concrete pavers. The maintenance information in this guide is intended for Unilock permeable paver systems only and not for other types of permeable pavers or pervious systems. Maintenance is necessary for any type of permeable pavement system, much like any impervious pavement with catch basins and underground infrastructure. Over the lifetime of the permeable paver system there will be a need to clean any sediment, soil, dirt and debris from the joint aggregate material to maintain a sufficient infiltration rate. Every project will vary in performance needs, as well as to the frequency in which the joint material must be cleaned. The surface infiltration rate must be greater than the regional 100 year rainfall intensity to adequately ensure no runoff is generated, which is only one goal for using permeable pavers. Unilock® suggests establishing a maintenance plan using the techniques in this document to prevent clogging. 2 Preceding Maintenance ...................................................................................... 4 Examples of Common Maintenance Issues ....................................................... 4 Maintenance Types .............................................................................................
