Washington D.C. DDOT Green Infrastructure Standards

May 1, 2014

In 2014, the District of Columbia Department of Transportation (DDOT) released design requirement standards for Green Infrastructure (GI) design, construction and maintenance in the public right-of-way. The intent is to provide stormwater retention to meet the regulatory requirements, along with the infrastructure requirements within the public right-of-way. The standards were developed for Low Impact Development techniques including bio-retention, permeable pavement, and street tree space design.

Encroaching Tides: How Sea Level Rise and Tidal Flooding Threaten U.S. East and Gulf Coast Communities over the Next 30 Years

October 2014

This report from the Union of Concerned Scientists describes the threat of tidal flooding in the East Coast and Gulf regions and offers steps that communities can take to adapt. The report makes the case that tidal flooding, currently just considered a nuisance, could become a daily or weekly occurrence, redefining how and where people along the coast “live, work, play, and move through their daily lives. " Data was collected in 52 locations to provide projections for sea level rise and tidal flooding in the region until 2045.

Washington D.C. Smart Roof - Roof Asset and Energy Management Program

Through the Smart Roof Program, the Washington D.C. Department of General Services (DGS) is successfully integrating roof asset and energy management projects to reduce its energy use by 20 percent across its entire municipal portfolio. The strategic approach to portfolio-based roof management is being applied across 435 buildings including schools, police stations, fire stations, parks and recreation centers, and office buildings that make up 321 acres of roof area in D.C.

Washington D.C. Green Roof Program

2007

In 2003, the Chesapeake Bay Foundation initiated a green roof demonstration project funded under the terms of a consent decree negotiated by the D. C. Water and Sewer Authority. The money was used to issue grants for the installation of eight different pilot green roofs that would reduce the cost of each green roof cost to the building owner by up to 20 percent. The pilot roofs served as models that building owners could use for future green roof projects, by providing data on costs, construction methods, performance, and maintenance needs.

Delivering Urban Resilience: Costs and benefits of city-wide adoption of smart surfaces

2018

This report quantifies the benefits and costs of smart surface technologies and finds that the risks from extreme heat and weather can be offset by these technologies. It draws on  Washington D. C. , Philadelphia, and El Paso as case studies and considers five smart surface technologies: cool roofs, green roofs, solar PV, reflective pavements, and urban trees. The authors find that adopting these technologies can generate millions (or even billions) of dollars in net financial benefits at the city level and can generate half a trillion dollars in net financial benefits nationwide.

Washington DC: Targeting Urban Heat Islands

August 2015

This case study discusses how Washington DC is preparing for the impacts of climate change including sea-level rise, increasing flood risks, and heat waves. The case study explores how District agencies integrated considerations of climate change when developing the city's Sustainable DC plan, which was developed through an interagency working group.  This effort spurred the development of a city-wide vulnerability assessment and adaptation plan.  The case study also explores the District’s efforts to reduce urban heat islands by making grants to pilot the use of cool roofs, implementing the Smart Roof Initiative to retrofit District-owned buildings, and adopting of a new Green Building Code.

Resilience for Free: How Solar+Storage Could Protect Multifamily Affordable Housing from Power Outages at Little or No Net Cost

October 14, 2015

This report from the Clean Energy Group uses project data for buildings in New York, Chicago, and Washington, D. C. , to examine the financial case for installing solar photovoltaics (PV) and battery storage systems (“solar+storage”) to support multifamily affordable housing. With the right market structures and incentives, solar+storage systems can provide an economic return, on par with energy efficiency or stand-alone solar. They can also help make affordable housing energy resilient by guaranteeing power for common area lighting, water, and communications.

DC Water Green Infrastructure, Clean Rivers Project (District of Columbia/Washington D.C., Virginia, Maryland)

May 2015

The District of Columbia Water and Sewer Authority (DC Water), the District of Columbia, the U. S. Department of Justice and the U. S. Environmental Protection Agency (EPA) have established an agreement which allows DC Water to pursue an integrated green/gray infrastructure approach to reduce combined sewer overflows into rivers and to capture rainwater. The agreement addresses water quality and supply issues in the Rock Creek and Potomac watersheds which traverse Maryland, Virginia, and the District.

Washington, DC Flood Levee System Improvements

December 2014

To prevent water from the Potomac and Anacostia rivers from flooding downtown Washington, D. C. , the U. S. Army Corps of Engineers (USACE) is improving the levee system along the north side of the National Mall, running from the Lincoln Memorial to the Washington Monument.   A levee system was originally erected to protect the District in 1939, following a major flood event in 1936.   This project will improve the levee system through a series of upgrades: a permanent closure at 23rd Street and Fort McNair, and the installation of a more robust removable wall, which will provide flood protection but also allow for traffic flow on 17th street between flood events.

Staying Green: Strategies to Improve Operations and Management of Green Infrastructure in the Chesapeake Bay Watershed

Staying Green discusses the barriers to and recommendations for effective operation and maintenance of green infrastructure practices for stormwater management. Green infrastructure (GI) requires proper maintenance to function effectively and continue to provide climate change adaptation benefits, such as urban heat island and flood mitigation. This report offers specific strategies, based on examples from throughout the Chesapeake Bay region and the country, to improve the operations and maintenance of GI practices.
