Incentives are a creative tool local governments can use to encourage the use of greeninfrastructure practices on private property. Incentive mechanisms allow municipalities to actbeyond the confines of their regulatory authorities to improve wet weather management on

properties that may not fall under updated stormwater requirements or other state and municipalpolicies, codes and ordinances. These incentives can be applied to both new developments andexisting developments. For new development projects, incentives can be incorporated into thedevelopment processes, such as building permits and stormwater permits or other developmentcodes and requirements, to creatively encourage green infrastructure. In already developed areas,incentives can be designed to encourage private property owners to retrofit their properties toinclude green infrastructure practices where they do not already exist. Examples of localincentive mechanisms can include stormwater fee discounts, expedited permitting, grants, rebateand installation financing, and awards and recognition.

This chapter includes a list of incentive mechanisms currently being used by municipalities

around the United States. The incentives have been organized categorically by type of incentive.The following are the primary types of green infrastructure incentives:

Stormwater Fee Discount: Require a stormwater fee that is based on impervious surface area. If property owners reduce need for service by reducing impervious area and the volume of runoff discharged from the property, the municipality reduces the fee.

Development Incentives: Offered to developers during the process of applying for development permits. Examples include: zoning upgrades, expedited permitting, reduced stormwater requirements and increases in floor area ratios.

Grants: Provide direct funding to property owners and/or community groups for

implementing a range of green infrastructure projects and practices. Rebates & Installation Financing: Provide funding, tax credits or reimbursements to

property owners who install specific practices. Often focused on practices needed in certainareas or neighborhoods

Awards & Recognition Programs: Provide marketing opportunities and public outreach forexemplary projects. May include monetary awards.

Incentive mechanisms can be easy to implement and afford local decision makers the flexibility

and creativity to tailor programs to specific priorities or to particular geographic areas in acommunity. For example, as seen in Figure 1, Portlands downspout disconnection program isdefined by the areas of the City with a combined sewer system. By offering an incentive of $53to disconnect a downspout, the City of Portland is encouraging private property owners in thedefined program area to reduce the runoff that enters the combined sewer system. Thisgeographically-specific approach allows a municipality to focus resources and program effortson a more manageable scale and can be an opportunity to pilot new incentives to determine thepotential for municipality-wide application. Similarly, the City of Seattles Green Factor

landscaping program is designed to increase the quantity and quality of planted areas in Seattle.The Green Factor is limited to downtown business districts because of the economicdevelopment potential of improved green space in the urban core and also because it allows theCity to pilot the program in a defined area before applying it to other areas and zoning types inthe city. Furthermore, incentive programs are voluntary, which creates less resistance from

stakeholder groups and allows policy makers to test and refine programs that may one daydevelop into mandates or requirements.

Figure 1: The map on the left shows Portlands combined sewer area and the map on the right shows the samegeographic area outlined as neighborhoods targeted to receive incentives for disconnecting downspouts.Directing incentives to specific zones with water quality issues can help achieve measurable results.

Descriptions of Incentive Types

Stormwater Fee Discount

Incentives tied to stormwater fees encourage retrofits of existing properties and implementationof green infrastructure in new developments. In cities of varying sizes across the United States,fee discounts and credits provide an opportunity for property owners to reduce the amount ofstormwater fees they pay by decreasing impervious surfaces or by using green infrastructure

techniques that reduce the amount of stormwater runoff. In turn, public infrastructure is lessburdened when private property owners manage their own stormwater runoff on-site. Discountsalso support the fee-for-service system because property owners can reduce the amount they payby reducing the service received.

Before setting the credit standard or discount, whether for the use of green infrastructure orreductions in impervious surfaces, municipalities should set appropriate management goals anddetermine how to credit private property owners for whatever action is being incentivized. Table

5/35

1 outlines common frameworks for setting goals and developing the process for implementingfee discounts.

Some cities provide a percent discount for level of performance. This discount is primarily givenfor stormwater quantity reductions and in fewer cases for pollution reduction for water quality

purposes. Discounts are also offered for impervious surface reductions, whether for total area orby the square foot. A credit system can be based on the implementation of specific practices,such as rain gardens, green roofs or even tree canopy area. In some cases, credits vary based onthe practice and the goals the municipality has for private lands.

Development IncentivesDevelopment incentives apply to private developers that take initiative by using more sustainablesite design and green building practices. These incentives are typically provided within theframework of existing land use or development regulations and often remove or decrease fees,

requirements, or steps in the permit process. Chicagos Green Permit Program reviews permitsmuch faster, even in as few as 30 days, for projects that meet certain LEED (Leadership inEnergy and Environmental Design) criteria that include better stormwater management practices.Portlands Floor Area Ratio (FAR) Bonus increases a buildings allowable area in exchange foradding an ecoroof/greenroof. Portland has seen over $225 million in additional privatedevelopment through this program, and more than 120 ecoroofs have been built in the center citydistrict. These incentives can be used to improve environmental performance and supporteconomic development. Development incentives also can be used to encourage greeninfrastructure beyond the site scale by encouraging infill development, aesthetically pleasing andwalkable neighborhoods, and compact, mixed use community designs.

Grants

Grant programs can be used to disburse money directly to individual homeowners, other propertyowners and community groups for stormwater-related projects and can help a city or county addgreen infrastructure projects to the landscape. Grants can be used to encourage both site-specificgreen infrastructure practices such as rain gardens, street retrofits, green roofs, and cisterns, aswell as neighborhood and municipal scale projects such as wetland construction or streamrestoration projects. Santa Monica provides $160,000 per year in Landscape Grants to developsites with native landscaping that reduce water consumption and absorb runoff. Chicagos GreenRoof Grant program has helped this former industrial city add over 2.5 million square feet ofgreen roofs across the City. The program grants $5000 awards to residential and small

commercial buildings that meet criteria based on location, visibility and environmental benefit.Green infrastructure grant programs provide awards and savings to developers and propertiesthat take extra steps to add greener stormwater management practices to both new and existingsites.

Rebates and Installation Financing

Communities offer rebates and installation financing to provide incentives for property owners toinstall green infrastructure practices on their property. These rebates and financing opportunitiesare often targeted to specific areas with the greatest need for green infrastructure, most oftencombined sewer areas. However, these programs may also be developed to achieve a range ofwater quality goals and implement community livability initiatives. For example, subsidies mightbe provided in neighborhoods with a high percentage of imperviousness or limited access topublic green space.

Rebates and financing tools are also commonly used to encourage the use of specific practicesbased on priority environmental and community goals such as cisterns for water conservation,rain gardens to improve groundwater recharge, and green roofs to mitigate urban heat islandeffects.

Rebates and installation financing are also an effective means of educating the public about thebenefits of green infrastructure and how it can be applied to a variety of property types andsettings.

Awards and Recognition Programs

Awards and recognition programs highlight successful examples of green infrastructure in acommunity. Award winners often include businesses and property owners as well as non-profitorganizations, community organizations, individuals, schools or government agencies. Awardsare provided to recognize innovations in green infrastructure practices and design, and mayinclude projects or plans that focus on water conservation and reuse, stormwater mitigation andmanagement, landscaping and site design, watershed restoration and other sustainable strategiesfor water quality protection.

Granting awards to local projects gives valuable recognition to innovators that help to drive thefield forward. At the same time, awards increase public awareness about local projects and the

ways that stormwater can be used as a valuable resource. Adding signage to award-winningprojects can help further educate the public and help the public recognize its impacts andconnection to the local watershed.

GA: Gwinnett County

Incentive Type: Stormwater Fee Discounts

Program Name: Stormwater Credits Program

Description: The County provides stormwater credit to landowners who install four types of

practices: watershed stewardship, water quality, peak flow and channel

protection. The total maximum credit for any property is 40%. Watershed

stewardship practices include: public participation, low impact parcels, farmlanddeep tillage, stream restoration / streambank stabilization, watershed

improvement project participation, conservation easements, conservation use

valuation, assessment (CUVA) properties, county approved training programs,

stream buffers that exceed 75 standards, fencing livestock out of streams, rain

barrels, automatic sprinkler sensors, direct discharges, septic tank maintenance,

and connection to sanitary sewers. Water quality credits of up to 10% are earned

by property owners who install facilities that capture pollutants, thereby

providing treatment of stormwater before it enters streams. There are several

practices to accomplish this available to all property owners. Porous pavement,

roof gardens and green roofs are acceptable practices to receive this credit.

Residential property owners can install rain gardens to earn this credit. Channel

protection credit (maximum 10%) is earned by property owners who provideprotection of stream channels from bank and stream bed erosion by detaining and

reducing the volume of stormwater from their properties. Peak flow credit

(maximum 10%) is earned by property owners who install basins that delay the

h ge system, thereby protecting downstream

p

ighest flows from reaching the draina

roperties.

Beneficiary: Property owner in Gwinnett County.

MN: New Brighton


Program Name: Stormwater Utility Credits

Description: City allows property owners discounts on utility fee based upon the propertys

average runoff depth and how that depth compares to the mean depth for the

propertys class type. For every percentage point the propertys runoff depth is

below 20% of the average class type flow, the property owner gets a percentagepoint discount. Additional discounts are given if the propertys peak outflow rate

is less then predevelopment for the five and 100 year storms, if a propertys wet

pond meets Nationwide Urban Runoff Program (NURP) standards, or if a

residential property owner installs and maintains a biorention/raingarden.

Beneficiary: Property owner in New Brighton, Minnesota.

MN: Saint Paul


Program Name: Rate of Discharge Credit

Description: St. Paul provides a rate of discharge credit for nonresidential properties, which is

based on parcel acreage and a standardized peak runoff rate determined for

selected land-use classifications. Where the peak stormwater runoff rate from a

parcel is limited by onsite facilities such as detention ponds owned and

maintained by the property owner, a credit of up to 25% is available. A 10%

credit is given for parcels that provide onsite storage for 5-year storms and also

limit discharge to a maximum of 0.11 m3/ha/s (1.64 ft3/ac/s). An additional 15%

credit is allowed for parcels that provide onsite storage for 100-year storms and

limit discharge to a maximum of 0.11 m3/ha/s (1.64 ft3/ac/s). Both newdevelopments and redevelopment projects may apply for the credit. Existing

nonresidential properties can retrofit their systems to provide onsite storage for 5-

year storms for a 10% credit. Most credits were provided in the first few years

after the program was established. Currently, approximately three to four credits

are approved annually. In St. Paul, the credit approach increased the political

acceptability of the storm sewer system charge.

NC: Durham


Program Name: Stormwater credit

Description: Durham provides up to a 25% pollution credit for selected structural stormwater

controls on nonresidential properties. The city first offered credits for onsite

retention basins based on the pool volume for retention. Later, the city offered

credits for onsite extended detention and extended detention-retention basins

based on drawdown time. Currently, the maximum pollution credit goes to

standard basin designs that achieve maximum pollutant removal efficiency under

North Carolinas performance standards. For other structural controls listed in the

states standards, the citys pollution credit is linearly variable, with a maximum

25% credit for a removal efficiency of 85% of total suspended solids. The city

recently approved the use of sand filters in addition to approved onsite basin

designs, but no pollution credits have been established yet for their use. Durham

receives few applications for credits.

OR: Portland


Program Name: Clean River Rewards Incentive and Discount ProgramDescription: Provides financial incentives to property owners who manage stormwater on

their site through a discount on their monthly stormwater utility charge. ThePortland City Council instituted a two-part rate35% of the charge for providingdrainage services to the property and 65% of the charge to provide drainageservices to the public right of way that served the property. Not only did thecharge breakdown reinforce that street drainage is an issue the City must dealwith, it also allowed a portion of the rate to be discounted for propertiesproviding onsite stormwater management. So with 35% of the stormwater rate upfor a potential discount, some properties could be encouraged to make retrofitchanges. The CRID has a simplified discount program for residential propertiesbased on volume control, and a more complex commercial property program that

requires water quality and flow control for the full discount.Beneficiary: Residential and Commercial

TN: Knox CountyIncentive Type: Development Incentives

Program Name: Impervious Area Disconnection

Description: This credit may be granted when impervious areas are disconnected from thestormwater control system via overland flow filtration/infiltration (i.e., pervious)zones. These pervious areas are incorporated into the site design to receive runoff

from rooftops or other small impervious areas. If impervious areas are adequatelydisconnected in accordance with the criteria listed below, they can be deductedfrom the total site area when computing the water quality volume requirements.



TN: Knox County


Program Name: Water Quality Volume Credits (General term for all specific credits)

Description: Allows for a reduction in the water quality treatment volume (WQv). The creditsystem directly translates into cost savings to the developer by reducing the sizeof structural stormwater control and conveyance facilities. If a developerincorporates one or more of the credited practices in the design of the site, therequirement for capture and treatment of the WQv will be reduced. Site designersare encouraged to utilize as many credits as they can on a site. Greater reductionsin stormwater storage volumes can be achieved when many credits are combined(e.g., disconnecting rooftops and protecting natural conservation areas).
