LID Stormwater Practices Source: EPA (2007) Reducing Stormwater Costs Through Low Impact Development (LID) Strategies and Practices (EPA-841-F-07-006)

Conventional Subdivision Open Space Subdivision Not so good. Open Space Subdivision Good.

LID: Status of NH Adoption LID is an effective and efficient approach to stormwater LID may help mitigate extreme climate events and be more aesthetic (design) Introduction of bio-retention technology in Prince George's County, Maryland, in the mid-1980s Ask for hands on LID regs adoption. Who has adopted LID regulations?

Science-based, training and LID Performance Data

What’s the Hold Up? (canvass from some partners)… 1. Lack of education on what LID is. 2.  LID is not viewed as a viable option due to cost, maintenance. 3.  There isn’t enough specific language or guidance on the adoption of LID regulations. 4. Lack of support or regulatory insistence from state or federal governments. 5.  Engineers are not adopting it quickly. 6. Disinterest in new regulations. Hypothesis

Making LID Happen

Explore Non-Regulatory Opportunities to Work with Landowners And, there are opportunities to work with landowners to improve water quality. In these examples, Youth Conservation Corps have installed simple BMPs that reduce erosion and sedimentation within Balch Pond in Sanbonville, NH (Action-Wakefield)

York LID Ordinance: Simple Low Impact Design. “Each applicant is required to submit a statement  to the Planning Board documenting proposed Low Impact Design (LID) for the site, which will help to reduce stormwater volumes and help to enhance stormwater quality.” “LID includes, but is not limited to green roofs, rain gardens, tree wells, infiltration basins, and permeable pavement.  The applicant shall submit technical documentation about the suitability of such designs with the request for LID features.”  Simple…but doesn’t by itself control design

Rooftop Runoff 77 Not so good. Good. Good. Another alternative to managing rooftop runoff is to drain the runoff directly into rain barrels, which can store the water for later use in gardens, yards, or for house plants. Good. Source: Center for Watershed Protection 77

Street Width Many municipalities continue to have local codes or regulations in place that discourage or even prohibit impervious cover reductions Not so good. Residential streets should be designed to be as narrow as possible based on future traffic volumes without compromising safety. Typical streets are often excessively wide, increasing traffic speeds and making streets unfriendly to pedestrians. Good. Source: Center for Watershed Protection 73

Parking: Grading and drainage for LID parking lots directs runoff to bioretention and pervious pavement areas. Parking: When designing large parking lots, it is best to break up and direct flows to multiple LID features. During the grading process, care should be taken to avoid compaction of areas identified for bioretention areas. A patterned steel grate inlet conveys flow under a pedestrian walkway. A curb cut inlet directs stormwater runoff into a biofiltration planter. An overflow outlet conveys runoff that exceeds the bioretention area capacity. Continuous cross slope conveys the full aisle to an adjacent swale. Crowned slope conveys half of each aisle to the adjacent swale. Inlets and outlets direct runoff into, and out of, bioretention areas. Proper placement of inlets helps to spread runoff over the bioretention planting areas, which slows the flow and reduces erosion. Outlet, including overflow, structures direct excess runoff to the storm drain system or street. During construction, avoid placing overflow structures flush with the soil, which prevents the desired retention of stormwater in the bioretention area.

Parking & LID Minimize impervious surfaces and uses site grading to direct runoff to landscaped areas where LID strategies can be utilized Break up and direct flows to multiple LID features.

Permeable Paving Runoff Reduction Grass pavers Paving stones Porous asphalt Pervious concrete Reinforced turf

Infiltration: Not! Somersworth, NH Site Plan Regs

LID Residential Design Element: Shared Driveways Reduce Impervious Area

Somersworth Site Plan Regulation: Getting Support Over Time The City of Somersworth encouraged LID for many years with several successful projects. Before even drafting regulations, the City staff visited UNH/SC Discussed voluntary adoption of LID with developers Now that we know what they do, how did we adopt them. We took a capacity building approach in Somersworth. LID regulations proposed in 2011 passed City Council unanimously 20

From a stormwater perspective, visualize only the buildings being impervious and some of them will collect roof runoff and reuse as irrigation.

Acton,ME Stormwater Mgt Ordinance (proposed) “Impervious cover should be disconnected from the stormwater drainage network, through such techniques as infiltration, sheet flow over a pervious area, or other approved LID techniques.”
