Slide 1

Water is Good: Showcasing Low Impact Development in Our County A presentation by Your Name County Water Quality Coordinating Committee Date

Slide 2

EPA Watershed Initiative: Susquehanna River Headwaters, NY and PA

Slide 3

Basic Premise: Rainwater is Good!

Slide 4

More Basic Premises Creative, keen individuals plan our groups… .urban communities don't simply develop there! We modify our groups. Water can be composed into a place as a positive component. Re-directed/captured water can lessen urban overflow.

Slide 5

Low Impact Development Can Help!

Slide 6

coordinate stormwater administration right on time in site arranging exercises utilize normal hydrologic works as the incorporating system concentrate on counteractive action as opposed to moderation underline basic, nonstructural, low-tech, and ease techniques oversee as near the source as could be allowed circulate little scale rehearses all through the scene depend on regular components and procedures make a multifunctional scene

Slide 7

Common LID Practices Site related: Rain Gardens and Bioretention Vegetated Swales, Buffers, and Strips Tree Preservation Permeable Pavers Soil Amendments Impervious Surface Reduction Pollution Prevention and Good Housekeeping Building related: Rooftop Gardens Roof Leader Disconnection Rain Barrels and Cisterns

Slide 8

Rain Gardens Dish-formed dejection Gathers spillover Plants sift through poisons Advantages: Good for little parts Can be minimal effort, simple Beautifies arrive Significantly decreases overflow ("Rain Garden History" 2)

Slide 9

Bioretention Widely utilized idea Shallow bowl loaded with soil/sand Soil gives invasion Native plants channel contaminations Reduces impenetrable surface zone Esthetically satisfying (Davis)

Slide 10

Bioretention cont'd (Davis 1)

Slide 11

Two sorts of bioretention: End-of-pipe on location Ideal uses for bioretention: Parking parcel island (check cuts) Highway middle Rain cultivate Small parcels Bioretention cont'd

Slide 12

Vegetated Swales Long plunge, generally along street, goes about as a channel for stormwater Prevents dilute from streaming impenetrable surfaces Vegetation backs water off and sift through poisons (Rhodes 1-3)

Slide 13

Swales cont'd Wet swales support untamed life Slope and outline critical – excessively soak a slant can bring about disintegration Wide, shallow swales are simpler to keep up Dry swales can be cut Inexpensive and easy to construct (Rhodes 4)

Slide 14

Vegetated Buffers & Strips Natural vegetation lining streams or streets Catch and channel spillover and toxins Cut down on surges Prevent stream bank disintegration Habitat for sea-going life Provide shade; cool water temperatures Restore characteristic conditions ("Designing," Buffer Handbook)

Slide 15

Permeable Pavers Granular and permeable or made of interlocking squares Traps water as opposed to going about as conductor Reduces overflow (James 2)

Slide 16

Permeable Pavers cont'd Porous Asphalt Pervious Concrete Grid/Grass Pavers (plastic) Block Pavers PermaPave ™ ("Reducing Runoff," NEMO; PermaPave)

Slide 17

Soil Amendments Mix into soil Improve soil quality Increase soil's air circulation, penetration, and ability to hold water and supplements ("What is Soil?" NRCS Soils)

Slide 18

Use a dirt alteration to change physical properties of soil. (Davis & Wilson 4)

Slide 19

Construction destinations: Stabilize seepage ways Protect conduits Minimize clearing and reviewing Separate development into stages to abatement measure of uncovered soil Protect soak inclines Perimeter controls channel residue Advanced silt settling controls Certify temporary workers on ESC arrange execution Citizen watch Assess ESC hones after tempests Pollution Prevention & Good Housekeeping (Brown & Caraco 1997; EPA Construction 1-2)

Slide 20

Rooftop Gardens Reduce impenetrable zone Eliminate most/the majority of rooftop's spillover Shield and ensure rooftop Lower vitality costs Reduce "warm island" impact, enhance air quality ("Green Roofs," NEMO)

Slide 21

Three noteworthy plan variables: weight, waste, slant Layers: waterproof film assurance board protection water maintenance substrate deplete channel texture soil vegetation Rooftop Gardens cont'd Vegetation Soil Filter Fabric Drainage Water Retention Protection Course/Root Barrier Membrane (D'Annunzio; "Green Roofs" 1; Greenroofs 101)

Slide 22

Roof Leader Disconnection Roof pioneers associated with tempest sewer Cut off end of downspout, top sewer standpipe, join elbow and expansion to downspout; splashblock ("Downspout Disconnection Program")

Slide 23

Rain Barrels & Cisterns Collect water Use to water cultivate Install channel (more $) for family unit utilize Cut down on water charges Connect to downspout Mosquito-verification top Angled overflow pipe Spigot 1 " rain on 1,000 ft 2 rooftop = 600 lady water Downspout Sealed Lid Angled Runoff Pipe Spigot (Rain Barrel Guide)

Slide 26

Local Initiatives to Tackle Stormwater August 31, 2003 – August 31. 2006 The Upper Susquehanna Coalition: sorted out an oversight council of driving water asset staff from region organizations, zone universities, building/engineering firms and others to work with groups and establishments to recognize great post-development BMP's and empower their utilization in new development ventures. accumulated a brief reference book reference of post development BMP plans from promptly accessible sources pertinent to the Susquehanna River Basin with help from the oversight advisory group.

Slide 27

Prepared this PowerPoint presentation of post development BMP's to each USC part. Given a duplicate of the clarified LID list of sources Each Water Quality Coordinating Committee will: hold an enlightening meeting and distinguish existing practices . make two page outlines of each of the area cases of creative BMP's given by each USC province.

Slide 28

request each USC region for an improvement venture which could join an imaginative post-development BMP. The oversight advisory group will choose four (4) ventures for Demonstration Funding to outline the BMP as a component of the improvement extend (about $4000 each).   make synopses of the four Demonstration Site plans. give every province a duplicate of the rundowns of the area BMP's for joining into watershed and district methodologies to address urban spillover post development issues.

Slide 29

The principal Demonstration Project: The Tioughnioga River Trail – utilizing pervious surfaces along the course to test them and to instruct people in general.
