LID important Tool for DoD Planners DoD planners must comply with a myriad of watershed- based laws and regulations –Executive Orders –Clean Water Act and Safe Drinking Water Act NPDES storm water permits for construction, Phase II storm water MS4 permits EPA watershed rule for NDPES Permits (2003) –Local zoning ordinances DoD goal to be sustainable steward of its buildings, lands, and infrastructure in accordance with E.O.s and various voluntary agreements (e.g. Chesapeake Bay Agreement) LID in new construction and retrofits helps DoD managers achieve sustainable facility goals and cost- effectively minimize impacts on impaired watersheds!

Executive Orders Directing Sustainable Approaches EO 13327, Federal Real Property Asset Management, Feb 2004 –Use life-cycle costs for decisions –Incorporate environmental costs EO 13148, Greening the Government Through Leadership in Environmental Management, Apr 2000 –EMS by 2005 –Incorporate Beneficial Landscape Practices into Agency landscaping policies by Apr 01 EO 13123, Greening The Government Through Efficient Energy Management, Jun 1999 –Requires sustainable design principles be applied to the siting, design, and construction of new facilities. EO 13101, Greening The Government Through Waste Prevention, Recycling, And Federal Acquisition, Sep 1998 –Agencies should incorporate EO requirements into contracts, including real property acquisition and management.

How LID Is More Sustainable Grade to encourage sheet flow and lengthen flow paths. Maintain natural drainage divides to keep flow paths dispersed. Disconnect impervious areas such as pavement and roofs from the storm drain network. Preserve the naturally vegetated areas and soil types that slow runoff, filter out pollutants, and facilitate infiltration. Direct runoff into or across vegetated areas to help filter runoff and encourage recharge. Treat pollutant loads where they are generated, or prevent their generation.

LID Benefits ENVIRONMENTAL Reduces pollutant loads by volume reduction and filtering. Bioretention and green roof systems provide superior filtering of oil and grease, TPH, thermal pollutant reduction, atmospheric nitrogen deposition WATER CONSERVATION Reduces potable water consumption by minimizing irrigation requirements. Opportunities for cisterns for other non-potable uses. ENERGY MANAGEMENT Shading of parking areas. Vegetation orientation reduces energy consumption. Green roof provides energy benefits. MAINTENANCE Minimizes maintenance requirements through the utilization of water-efficient, native, adaptable, climate-tolerant plant material AESTHETICS Integration of natural landscape design with native plants and additional vegetation in bioretention cells. Green roof may be viewed from building.

LID Integration: Objectives Identify the LID objectives for the project. Consider these four fundamental aspects of stormwater control: Runoff Volume Peak Runoff Rate Flow Frequency and Duration Water Quality Determine the goals and feasibility for runoff volume, flow frequency and duration, water quality and on-site use of stormwater (e.g. irrigation). Define hydrologic controls required to meet objectives

LID Integration: Site Analysis Evaluate the site design for the best and most appropriate site design strategies Stormwater management controls should be located as close as possible to the sources of potential impacts. The objective is to consider the potential of every part of the landscape, building(s), and infrastructure Preference should be given to those that use natural systems, processes, and materials.

LID Integration: Benefit Analysis The cost-effectiveness of LID-based projects may affect DoD approval. LID projects that incorporate newer technology may involve higher design and construction costs and may take more time to receive approval depends on the level of experience that the project managers, engineers, and contractors have with LID techniques, and on the receptiveness of permitting authorities to LID practices. the cost of implementing LID will decrease as institutional experience increases and the benefits of using LID are realized in practice.

LID Integration: Site Design Selection A site evaluation will facilitate LID design development by providing site details that will assist in the development of an LID program. Conduct a detailed investigation of the site using available documents, such as drainage maps, utilities information, soils maps, land use plans, and aerial photographs. Perform an on-site evaluation highlighting opportunities, such as pollutant-generating areas, potential disconnects from CSOs, and potential green corridors. Evaluate site constraints, such as available space, soil infiltration characteristics, water table, slope, drainage patterns, sunlight, shade, wind, critical habitat, circulation and underground utilities.

LID Integration: Plan Development Identify protected areas, setbacks, easements, topographic features, subdrainage divides, and other site features that should be protected (i.e. floodplains, steep slopes and wetlands) Delineate the watershed and microwatershed areas. Take into account previously modified drainage patterns, roads, and stormwater conveyance systems. Locate baseline hydrologic and water quality data. In order of preference, try to locate: –Local stream gage data and site water quality sampling data –Data from a similar area within region –Local averages –Modeling results Identify applicable local regulations or codes.

LID Integration: Plan Development (continued) Use hydrology as a design element to minimize the runoff potential of the development. –open drainage systems can help to integrate the site with its natural features, creating a more aesthetically pleasing landscape. Determine design storm(s). Regulatory requirements for design storms may also be stipulated in local ordinances, and these may limit or constrain the use of LID techniques or necessitate that structural controls be employed in conjunction with LID techniques. Define modeling technique(s) to be employed. –The model selected will depend on the type of watershed, complexity of the site planning considerations, familiarity of the agency with the model, and level of detail desired. Evaluate current conditions.

LID Integration: Plan Development (continued) Implement non-structural site planning techniques: –Minimize total site impervious area –Use alternative roadway layouts that minimize imperviousness –Reduce road widths –Limit sidewalks to one side of roads –Reduce on-street parking –Use permeable paving materials, such as permeable pavers or porous asphalt. Minimize directly connected impervious areas Modify drainage flow paths to increase time of concentration (Tc) Define development envelope.

LID Integration: Plan Development (continued) Evaluate site planning benefits and compare with baseline values. The modeling analysis is used to evaluate the cumulative hydrologic benefit of the site planning process in terms of the four evaluation measures. Evaluate the need for Integrated Management Practices (IMPs). If site planning is not sufficient to meet site LID objectives, additional hydrologic control needs may be addressed through the use of IMPs. Evaluate supplemental needs. If after use of IMPs supplemental control for either volume or peak flow is still needed, selection and listing of additional management techniques should be considered.

LID Integration: Plan Development (continued) Design LID Site or Master Plan Sketch a design concept that distributes the LID practices appropriately around the project site. Develop a master plan that identifies all key control issues (water quality, water quantity, water conservation) and implementation areas. Specify specific LID technologies and any connections they have to stormwater overflow units and sub-surface detention facilities.
