4 4 INTRODUCTION In 2013, the Pssic Vlley Sewerge Commission (PVSC) begn new inititive to ssist the 48 municiplities within its jurisdiction to mnge flooding nd eliminte combined sewer overflows. With municiplities spred cross five counties, PVSC is dedicted to leding efforts throughout the PVSC Sewerge District by using green infrstructure to intercept stormwter runoff, reduce combined sewer overflows (CSOs), mnge existing wter infrstructure, nd minimize frequent flooding events. To help with this effort, PVSC hs entered into prtnership with the Rutgers Coopertive Extension (RCE) Wter Resources Progrm. North Bergen is community with combined sewer system which crries both wstewter nd stormwter in the sme pipes. During hevy rin or snow melt, combined sewer systems often cnnot mnge ll of the wter nd overflow, cusing combined sewer overflow (CSO) event. When overflows or CSO events occur, stormwter tht hs been mixed with untreted wstewter is dischrged into locl wterwys, crrying with it mny contminnts. By using cost-effective green infrstructure prctices, North Bergen cn begin to reduce the negtive impcts of stormwter runoff nd pressure on the locl infrstructure, while lso incresing resiliency to CSO events nd protecting the helth of our wterwys. This fesibility study is intended to be used s guide for the community of North Bergen to begin implementing green infrstructure prctices while demonstrting to residents nd locl leders the benefits of nd opportunities for better mnging stormwter runoff. Rutgers University professor, Tobih Horton, reviews rin grden design with homeowner.

5 NORTH BERGEN Locted in Hudson County, the Township of North Bergen is situted on the Hudson Plisdes between the Hudson River nd the Hckensck Medowlnds. The township covers n re totling bout 5.5 squre miles nd hs popultion of 60,773 ccording to the 2010 U.S. Census. As lndlocked town in densely populted re, North Bergen shres its border with mny other communities. North Bergen shres its northern border with the Bergen County communities of Ridgefield, Firview, Cliffside Prk, nd Edgewter. To the est is Guttenberg, West New York, nd Union City. Secucus is locted to the west, nd Jersey City is to the south. 5 The town hs combined sewer system with totl of seven combined sewer overflow (CSO) points. This mens tht in the event of hevy storm, much of the town s runoff nd wstewter trvels into nerby wter bodies untreted. By evluting the fesibility of green infrstructure, North Bergen cn identify cost-effective wys to help mitigte wter qulity nd locl flooding issues.

6 6 WHAT IS STORMWATER? When rinfll hits the ground, it cn sok into the ground or flow cross the surfce. When rinfll flows cross surfce, it is clled stormwter runoff. Pervious surfces llow stormwter to redily sok into the soil nd rechrge groundwter. An impervious surfce cn be ny mteril tht hs been plced over soil tht prevents wter from soking into the ground. Impervious surfces include pved rodwys, prking lots, sidewlks, nd rooftops. As impervious res increse, so does the mount of stormwter runoff. New Jersey hs mny problems due to stormwter runoff from impervious surfces, including: POLLUTION: According to the 2010 New Jersey Wter Qulity Assessment Report, 90% of the ssessed wters in New Jersey re impired. Urbn-relted stormwter runoff is listed s the most probble source of impirment (USEPA, 2013). As stormwter flows over the ground, it picks up pollutnts, including niml wste, excess fertilizers, pesticides nd other toxic substnces. These pollutnts re crried to wterwys. FLOODING: Over the pst decde, the stte hs seen n increse in flooding. Communities round the stte hve been ffected by these floods. The mount of dmge cused lso hs incresed gretly with this trend, costing billions of dollrs over this time spn. EROSION: Incresed stormwter runoff cuses n increse in strem velocity. The incresed velocity fter storm events erodes strem bnks nd shorelines, degrding wter qulity. This erosion cn dmge locl rods nd bridges nd cuse hrm to wildlife. Purple Coneflower A locl reservoir Pervious Pvers To protect nd repir our wterwys, reduce flooding, nd stop erosion, stormwter runoff hs to be better mnged. Impervious surfces need to be disconnected with green infrstructure to prevent stormwter runoff from flowing directly into New Jersey s wterwys. Disconnection redirects runoff from pving nd rooftops to pervious res in the lndscpe.

7 A community grden tht hrvests nd recycles rinwter Rin brrel workshop prticipnts A rin grden fter plnting WHAT IS GREEN INFRASTRUCTURE? Green infrstructure is n pproch to stormwter mngement tht is cost-effective, sustinble, nd environmentlly friendly. Green infrstructure projects cpture, filter, bsorb, nd reuse stormwter to mintin or mimic nturl systems nd to tret runoff s resource. As generl principle, green infrstructure prctices use soil nd vegettion to recycle stormwter runoff through infiltrtion nd evpotrnspirtion. When used s components of stormwter mngement system, green infrstructure prctices such s bioretention, green roofs, porous pvement, rin grdens, nd vegetted swles cn produce vriety of environmentl benefits. In ddition to effectively retining nd infiltrting rinfll, these technologies cn simultneously help filter ir pollutnts, reduce energy demnds, mitigte urbn het islnds, nd sequester crbon while lso providing communities with esthetic nd nturl resource benefits (USEPA, 2013). 7

8 GLOSSARY OF GREEN INFRASTRUCTURE TERMINOLOGY A DISCONNECTED: Disconnected refers to chnneling wter from gutters nd pipes tht collect runoff to somewhere other thn sewer drin where it cn be filtered. 8 B DEPAVING: Depving is the process of removing hrdscpe such s sphlt or concrete. C INFILTRATION: Infiltrtion occurs when wter on the ground s surfce is bsorbed into the soil below. Plnts promote infiltrtion. D IMPERVIOUS SURFACE: An impervious surfce is one tht wter cnnot penetrte. E RUNOFF: Runoff is wter from precipittion tht flows cross lnd nd pved surfces before entering locl wterwys or sewer systems.

13 GREEN INFRASTRUCTURE SYSTEMS 13

14 VEGETATED SYSTEMS Vegettive systems primrily focus on reducing wter qulity impcts nd less on reducing flooding. These systems re typiclly locted close to the sources of runoff nd cn mnge the smller storms of severl inches. The min tretment mechnisms re infiltrtion, filtrtion, nd evpotrnspirtion. These systems do n excellent job t removing totl suspended solids, nutrients, nd pthogens. Construction costs for vegetted systems re typiclly low to moderte when compred to other green infrstructure prctices. Since these systems often cn be incorported into existing lndscpes nd enhnce esthetics, the community cceptnce of vegettive systems is high. BUFFER The buffer surrounds rin grden, slows down the flow of wter into the rin grden, filters sediment, & bsorbs pollutnts from runoff. 14 PLANTING SOIL LAYER This lyer is usully ntive soil. It is best to conduct soil test of the re checking the nutrient levels nd ph to ensure dequte plnt growth. INLET The inlet is the loction where stormwter enters the rin grden. Stones re often used to slow down the wter flow nd prevent erosion. DEPRESSION The depression is the re of the rin grden tht slopes down into the ponding re. It serves s holding re nd stores runoff witing tretment & infiltrtion. ORGANIC MATTER Below the ponding re is the orgnic mtter. It cts s filter nd provides home to microorgnisms tht brekdown pollutnts. PONDING AREA The ponding re is the lowest, deepest visible re of the grden. It should drin within 24 hours. SAND BED If dringe is problem, snd bed my be necessry to improve dringe. Adding lyer of corse snd will increse ir spce nd promote infiltrtion. BERM The berm is constructed mound tht cts s brrier to control, slowdown, & contin the stormwter in the rin grden. It cn be vegetted nd/or mulched. OVERFLOW The overflow (outlet) re serves s wy for stormwter to exit the rin grden during lrger rin events. R A I N G A R D E N D I A G R A M

15 VEGETATED SYSTEM SUITABILITY Rin grdens re shllow lndscped depressions designed to cpture, tret, nd infiltrte stormwter runoff. Rin grdens cn be redily instlled throughout community to begin re-estblishing the nturl processes of the lndscpe. Rin grdens: Cpture stormwter runoff, reducing soil erosion nd sedimenttion nd the mount of wter tht flows to our strems nd wterwys during rin storms Protect wter qulity by filtering out nd breking down pollutnts Infiltrte runoff nd rechrge groundwter supplies by providing bse flow to nerby strems nd wterwys Enhnce nd increse green spce nd vegetted cover Rin grdens re simple wy communities cn begin to reduce stormwter runoff, mnge flows to sewer systems, nd protect wter resources.

18 RAINWATER HARVESTING SYSTEMS Rinwter hrvesting systems focus on the conservtion, cpture, storge, nd reuse of rinwter. These systems re locted close to residentil nd commercil buildings. Construction costs re low to moderte, depending on the size of the system, compred to other green infrstructure prctices. Since these systems cn be esily incorported into the built lndscpe, the community cceptnce of rinwter hrvesting systems is moderte to high. Rinwter hrvesting systems include rin brrels nd cisterns. 18 INLET Rinwter collected in gutters is relesed into the brrel here OVERFLOW OUTLET Releses wter when the rin brrel reches cpcity SPIGOT Vlve tht opens nd closes brrel s wter flow R A I N B A R R E L D I A G R A M

19 RAINWATER HARVESTING SYSTEMS SUITABILITY Typicl rinwter hrvesting systems cn store up to 5,000 gllons of wter. Hrvesting during the riny months of spring nd summer provides source of wter during hot nd dry periods between rin storms. Insted of using potble wter, residents cn sve money using the rinwter stored in rin brrel or cistern. This lso reduces the demnd on drinking wter supplies nd relted infrstructure Rin brrels nd cisterns re n effective rinwter hrvesting tool nd cn be n importnt element in community-wide green infrstructure progrm. For every inch of rin tht flls on n eight hundred squre foot roof (20' x 40'), nerly 500 gllons of wter cn be collected. Over n entire yer, wter drining from this rooftop will totl over 20,000 gllons. This sustinble prctice reduces the impct building hs on the environment by hrvesting stormwter runoff from rooftops nd decresing flow to sewer systems. Rin brrels nd cisterns provide n lterntive source of wter for grdens, lwns, nd lndscping by reducing the use of potble wter supplies SITE KEY School Municipl Public Spce Other 19

22 22 STORAGE, QUANTITY, & INFILTRATION SYSTEMS Storge, quntity, nd infiltrtion systems primrily focus on storge. These systems re typiclly locted close to runoff sources within residentil, commercil, nd industril lndscpes. The min tretment mechnism is reducing pek flows of stormwter by storing it before it becomes runoff. Construction costs for storge, quntity, nd infiltrtion re moderte to high when compred to other green infrstructure prctices becuse they require more spce nd infrstructure nd re more lborious to instll. Since these systems cn be semlessly incorported into the built environment nd cn mnge lrge quntity of wter, the community cceptnce of storge, quntity, nd infiltrtion systems is high.

These systems include: Permeble pvers Porous sphlt Pervious concrete The pving mteril is plced over bed of uniformly grded stone. The pving mterils llow wter to pss through nd then infiltrte into the pore spces of the underlying stone bed. The stored runoff then infiltrtes over time into the uncompcted subgrde soils. Stormwter plnters re smll, contined vegetted systems tht collect nd tret stormwter using prepred soil medi nd mulch. These systems serve s smll bioretention fcilities filtering stormwter through lyers of mulch, soil, nd plnt root systems.

28 BUILD A RAIN BARREL WORKSHOP 28 With the Build Rin Brrel Workshop, community members prticipte in short presenttion on stormwter mngement nd wter conservtion nd then lern how to build their own rin brrel. Workshop prticipnts work with trined experts to convert 55 gllon plstic food-grde drums into rin brrels. They re quickly ble to tke n ctive role in recycling rinwter by instlling rin brrel t their house! Hrvesting rinwter hs mny benefits including sving wter, sving money, nd preventing bsement flooding. By collecting rinwter, homeowners re helping to reduce flooding nd pollution in locl wterwys. When rinwter flows cross hrd surfces like rooftops, drivewys, rodwys, prking lots, nd compcted lwns, it crries pollution to our locl wterwys. Hrvesting the rinwter in rin brrel is just one of the wys homeowners cn reduce the mount of rinwter drining from their property nd help reduce neighborhood flooding problems.
