While some communities have limited market demand to redevelop property, revitalizing brownfields remains a priority. The revitalization process can improve local health and the quality of the environment, spur area-wide investment, increase the local tax base, and provide new jobs. Revitalizing waterfront brownfield areas can provide people with access to greenspace and recreation opportunities. These areas can play an important role in bolstering local resilience to increased flooding, storm surge, or temperatures from a changing climate. However, incorporating climate resilient features into redevelopment of these "climate vulnerable" properties can be resource intensive and may increase development costs. Therefore, careful consideration of long-term goals, best practices, and financing opportunities to meet both a community's revitalization plans and its resiliency requirements is necessary. PURPOSE The U.S. Environmental Protection Agency's (EPA's) Office of Land and Emergency Management (OLEM) Land Revitalization Program helps restore land and other natural resources into sustainable community assets that maximize beneficial economic, ecological and social uses, and ensure protection of human health and the environment. The Land Revitalization Program developed this tool to provide communities with practical, real-world examples of regulations, incentives, projects, and programs that local governments may consider to balance economic development goals with climate resiliency needs. The tool focuses on examples of regulations, incentives, projects, and programs that: Support revitalization of brownfields. Mitigate stormwater and flooding impacts. Could work in areas with low to moderate demand for development. Can be implemented by individual communities (as compared with approaches that require multi-community or regional collaboration). The examples provided in this tool are representative approaches that communities can review and consider for use in their own communities.1 The tool organizes the examples into three sections. Section 1: Ordinance Regulations and Development Incentives Section 2: Program and Project Approaches to Resiliency Section 3: EPA Climate Adaptation Planning Resources Provides examples of incentives and ordinance regulations that can be implemented without public or foundation money Summarizes relevant examples of projects, programs or approaches not directly applicable to land use regulations Provides several additional resources for communities to explore in climate adaptation planning that have been developed by EPA 1 This tool was originally developed for use in EPA Region 3, and included examples of land revitalization regulations, incentives, projects, and programs that are not well-known or widely-used in Pennsylvania, Delaware, and New Jersey. However, the examples compiled in this tool can be used as a reference by communities anywhere. 1 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Section 1 Ordinance Regulations and Development Incentives Increasingly, local zoning codes are written to specifically identify types of buildings and site features that are permitted without special approval, a permit, exception or variance. This tool identifies examples of incentives and ordinance regulations that use this technique to enhance climate resilience without requiring additional public or foundation money. This section of the tool summarizes examples of such regulatory and development incentives, organized as follows: Stormwater Management Incentives and Tools Example 1-1: Green Roof Tax Credits/Rebates (Philadelphia.

Businesses apply for a Green Roof Tax Credit that reduces its Business Privilege Tax by 25% of the costs of constructing the green roof, up to $100,000. Green roof costs range from $10 (extensive - i.e., shallow) to $25 (intensive - i.e., deeper) per square foot, and tend to extend lifetime of roof by 10-200%. o Extensive green roofs contain up six inches of soil, are lightweight, accommodate shallow rooted plants, and provide baseline stormwater management, insulation, and ecological benefits. o Intensive green roofs contain more than six inches of soil, accommodate a variety of plants, require greater roof loads, and provide greater stormwater management, insulation, and ecological benefits. According to Greenroofs.org, "in summer, depending on the plants and depth of growing medium, green roofs retain 70-90% of the precipitation that falls on them; in winter they retain between 25-40%. For example, a grass roof with a 4-20 cm (1.6"-7.9") layer of growing medium can hold 10-15 cm (3.9"-5.9") of water." Stormwater Management Incentives and Tools Example 1-2 Green Roof Rebate (Nashville, TN) Source: http://www.nashville.aov/Water-Services/Developers/Low-lmpact-Development/Green-Roof-Rebate.aspx Incentivizes green roof construction by offering a credit of $10 per sq. ft. of green roof construction cost against monthly sewer charges for the property for up to 60 months. Required a partnership between the city and provider Metro Water Services. 3 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Stormwater Management Incentives and Tools Example 1-3 RainScape Rewards Program (Montgomery County, MD) Sources: http://www.montaomervcountvmd.gov/DEP/water/rainscapes-rebates.html http://www.montaomervcountvmd.gov/DEP/water/wapc-rates.html www, green roofs, org County offers technical and financial assistance and "Rainscape Rewards Rebates" or up to $2,500 to residential properties and up to $10,000 for commercial, multifamily, and homeowner association projects, for work that reduces stormwater runoff volume and improves water quality on properties. Project types include the planting of canopy trees, removal of impervious pavement, or installation of conservation landscaping, dry wells, green roofs, permeable pavement, rain gardens, rain barrels, or cisterns. Rebate issued after project passes final inspection. Funding source is a county Water Quality Protection charge, which appears as part of the Montgomery County property tax bill. o Raises funds to support clean water initiatives to improve stream and water quality and prevent stormwater pollution. o Charge applies to all residential and commercial property owners and is calculated based on the potential for a property to contribute to stormwater runoff. Larger, more developed property produces more runoff. o Calculated based off of ERU (Equivalent Residential Unit) statistical median of the total horizontal impervious area of developed single family detached residences in the County serving as a base unit of assessment. o In 2014, one ERU equals 2,406 square feet, which equals a charge of $88.40. 4 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Stormwater Management Incentives and Tools Example 1-4 Green Infrastructure Tools (Nashville, TN) Sources: www.nashville.aov/Portals/O/SiteContent/WaterServices/Stormwater/docs/reports/GreenlnfrastructureRptl 01120.pdf www.nashville.aov/Water-Services/Developers/Low-lmpact-Development.aspx Although Nashville implemented the following solutions as part of its Green Infrastructure Master Planwhich coincides with its combined sewer overflow areamany of the green infrastructure tools identified could be implemented through a local landscape or site design ordinance. Green Infrastructure tools included in the plan focused on retrofits for existing developments and designs for future development. Tools to be implemented, and approximate costs for those tools, included: o Downspout Disconnection: <$ 100 per disconnection. o Filter Strip: < $1 per square foot. o Infiltration Practices: $5 per cubic foot of stormwater treated. o Pocket Wetlands: $1.50 per cubic foot stormwater treated. o Permeable Pavement: $5-$15 per square foot. o Rain Barrels/Cisterns: $1 per gallon of stormwater stored. o Rain Gardens/Bioretention: $3-$4 per square foot for simple residential designs; $10-$40 per square foot for more complex commercial designs. o Soil Amendments: < $1 per square Potential Funding Sources for Nashville, Tennessee, Green Infrastructure Tools: Loans and grants through HUD, FEMA, EPA Tennessee State Revolving Loan Fund (development and maintenance of drinking water and wastewater infrastructure) Tennessee Clean Water State Revolving Fund Loan Program (planning, design, and construction of wastewater facilities) Tennessee Department of Environmental Conservation Green Development Grant (green infrastructure and low impact development) Clean Water Infrastructure Program (improvements/upgrades to Metro's stormwater management systems) Land Trust for Tennessee (nonprofit) Metro Greenways Commission (nonprofit) Tax Increment Financing Community Development Block Grants foot. o Street Trees and Afforestation: Seedlings range from $6 to $25 depending on size, o Tree Box Filters: $12,000-$15,000 per 6'x6' unit, o Vegetated Roofs: $5-$25 per square foot, o Vegetated Swales: $0.50 per square foot. Role of Metro Water Services (which is a part of the city government): o Developed a Green Infrastructure Master Plan. o Published a Stormwater Management Manual, training videos, and training presentations. 5 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 o LID (Low Impact Development) Site Design Tool: An online tool that aids engineers in designing the water quality treatment for a project in accordance with the methodology in the LID manual and to see if the design meets Metro's water quality requirements. o Funding through stormwater fees, loans, and grants. o Maintains a list of recommended contractors for maintaining stormwater best management practices (BMPs). One key lesson learned was the that city must take responsibility for maintenance of the low impact development features after installationboth to ensure that they continue to function as designed, and to avoid property owner reluctance to install features that they will then have to maintain. Clarion's experience confirms this lesson. Example projects: Bioswale at the Hill Center Belle Meade. Pervious concrete parking at Tennessee Association of Realtors.

Discount created for customers who reduce impervious cover using green infrastructure practices including rain gardens, infiltration trenches, porous pavement, vegetated swales, and green roofs. Residential and other small-meter customers do not require detailed analysis, because of the administrative difficulty and cost required for detailed analysis of 450,000 residential properties. So all residential properties are combined and treated as a single land parcel, with total costs of the 80/20 calculation divided equally among all households. Stormwater costs spread out and shared over larger customer base; calculations show majority of customers will see a reduction or otherwise minor impact to bill. According to a HUD article, the program has successfully created greenspace. The program is "well on its way to achieving its 5-year goal of approximately 750 greened acres (1.2 square miles) within the combined sewer system (CSS) area largely due to commercial, industrial, and institutional property owners trying to reduce stormwater fees on their properties." Stormwater Management Incentives and Tools Example 1-6 Stormwater Fee Discount for Non-residential Property Owners (Toledo, OH) Source: https://louisville.edu/cepm/proiects/sustainable-communitv-capacitv-buildina/ai-strategies Program identifies several different practices that property owners can install to reduce stormwater runoff and establishes different discount percentages for each: o 10% discount for brownfield reuse; o 30% discount for installing forested buffer or swale. Maximum discount is 50% of stormwater fee, is applicable only to the impervious area controlled by the practice, and is awarded only for fully constructed/functional practices. 7 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Land Use and Building Codes and Regulations Land Use and Building Codes and Regulations Example 1-7 Compensatory Floodplain Storage Model Regulatory Text (Nashville, TN) Source: http://www.floods.org/ace-files/documentlibrarv/connmittees/l-lipher Stds Ref Guide 07-12-11.pdf Text included requiring development to compensate for the loss of floodplain storage caused by filling in the floodplain, which can result in raising flood elevations. Model text reads: (1) Add to language for the Assurance of Flood Carrying Capacity: o Compensatory Storage Required for Fill "Fill within the special flood hazard area shall result in no net loss of natural floodplain storage.

Infiltration BMPs include site design that facilitates the percolation of runoff through the soil to ground water. Ordinances should require a minimum of 15 percent greenspace, with incentives for additional greenspace and preserving existing trees. Examples include infiltration islands/trenches, green roundabouts, dry wells, and porous pavements. Vegetative BMPs include landscaping features that remove pollutants and facilitate percolation. Examples include grass swales, filter strips, artificial wetlands, and rain gardens. Other BMPs such as the use of cisterns and rain barrels store rainfall, which in turn reduce runoff, and can be used for activities such as lawn care and washing vehicles.

Elevation is preferred over flood proofing for new construction. o For slab-on-grade foundation on structural fill, the fill must be designed to minimize adverse impacts such as increasing flood elevation on adjacent properties, increasing erosive velocities, and causing local drainage problems. o For solid foundation walls, open foundations, piles, piers, columns, or posts are recommended if velocities are high or debris load is anticipated. o When practical, Design Flood Elevation (DFE) should be at or above the BFE. Dry Floodproofing measures include: o Installing watertight shields for doors and windows and using membranes and sealants to reduce seepage of floodwaters (walls must be design checked to resist the additional water loads). o Reinforcing walls to withstand floodwater pressures and impact forces generated by floating debris. o Installing drainage collection systems, sump pumps, and check valves to control water levels and prevent floodwater backflows. Requirements for use of use of flood damage resistant materials include: o Only FEMA Technical Bulletin 2, Flood Damage-Resistant Materials Requirements (FEMA 2008a) class 4 and 5 materials are acceptable for use below the DFE. Steps to protect electrical and mechanical systems from flood hazard events include: o Elevation of equipment and under-floor utilities and ductwork to a height above the DFE. o Electrical and other conduits below the DFE should be located and anchored to resist the effects of flooding. o Utilities and equipment located outside of the building must be elevated on platforms that are attached to the primary structurethese platforms should be designed to resist all flood loads. Steps to protect potable water and wastewater systems from flood hazard events include: o Onsite water supplies should be located on land elevated above the surrounding landscape to allow contaminated surface water and runoff to drain away from the site. o Sewer collection lines should be located and designed to avoid filtration and backup due to rising floodwaters. Secondary backup devices should be used as redundant measures of protection. 13 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Best Practices, Guidance, Recommendations Example 1-14 Shield panel Stronger, More Resilient New York Recommendations (New York, NY) Source: http://www.nvc.gov/html/sirr/html/report/report.shtml 98% of buildings destroyed and 94% of buildings severely structurally damaged during Superstorm Sandy were built before 1983.

The study is a resource and a guide. None of the recommendations have been implemented into ordinance, local law, or code. The study understands that regulations must seek a balance of promoting economic development, quality of life, and environmental protection and therefore seeks low-cost, effective means of reducing pollution and increasing flood resiliency. Many zoning codes are limiting in their definitions of open industrial uses. New York City currently classifies most open industrial uses as "junkyards." o "Other cities have adopted or proposed new zoning regulations that, while seeking to limit or control the operations of open uses, also acknowledge that these uses are more than junkyards and in fact represent a number of industries of growing importance as urban populations grow and public polies seek to promote and even require recycling." The study proposes a zoning text amendment that will require existing and new industrial uses, whether in currently conforming or non-conforming status, to comply with new physical design standards for effective onsite pollution prevention control and flood hazard mitigation. Examples of design standards: o Paving and grading of activity and storage area with an impervious surface, sloped to direct runoff into a drainage system. o Installation of a drainage system for the paved area, including appropriate treatment, filtration, and dentition systems designed to treat captured contaminated water before it is released back into the sewer systems or waterways. o A limitation on the height of material piles such that no pile shall be higher than the fence or wall. o Covering all open materials where feasible. The study encourages the use of green infrastructure tools as a secondary treatment approach due to its cost effectiveness. The technology must be used carefully and should be well maintained to ensure contaminants are not absorbed into the soil or ground water in concentrated volumes. The study encourages the use of emerging pollution controls such as vegetative barriers, phytoremediation (using plants to treat and mitigate pollutants), and package wastewater treatment systems for small facilities that can treat, process, and recycle stormwater on site. 17 ------- debrif, duslpi carried inti *0, Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Certain conditions are unique to NYChigh density, small sites, absence of buffering adjacent to residences, and tendency of open industrial uses to locate in flood zones.

Investments can be made to accommodate floodwater flows or storm surges in new types of facilities and areas, or to improve the defensibility of key sites or public facilities. In addition, communities have responded to the increasing need for climate resilience by beginning multi-stakeholder plans that bring together behavior change education with strategic investments. This section of the tool provides examples of community- based programs and projects to increase climate resilience, organized as follows: Integrated Water Management Example 2-1: Coastal Resiliency Measures (New York.

The publication advocates for an integrated approach to flood protection systems that includes a variety of elements that can be combined and customized in areas where critical infrastructure or vulnerable neighborhoods require a high level of flood protection. The elements of the integrated approach can include the following: o Landscaped features such as terraces, berms and waterfront parks, o Flood-proofed buildings or bridge abutments, o Drainage improvements including valves and gates. o Temporary features such as deployable floodwalls which can be affixed to permanent in-ground foundations. The publication serves as a guide to coastal resiliency measures and does not include a list of proposed regulations. However, some of its recommendations are making their way into law. o For example, the New York City Building Resiliency Task Force recommends allowing building owners to install temporary flood barriers on sidewalks. This recommendation led to the passage of Local Law 109/13, allowing removable flood barriers on public sidewalks. 23 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Integrated Flood Protection System Permanent floodwall Deployable floodwall Landscaped berm or levee Floodable zone Pipe treatment to prevent backflow Anticipated surge water level- Typical water level ¦ Integrated Flood Protection System An example of New York City industrial shoreline. 24 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Typical Coastal Resiliency Measures |snf I REACH sin ccusrum I iH-WATBt Dry noodproofing Elevation of Land and Streets Bulkheads Wet Floodproolinp Elevate on Fill or Mound Elevate on PHes Site Protection Resting Structures Otployabe Floodwjtlls Revetments Living shorelines Permanent floodwalls Btiic hes jr.a Dunes WdteHiorvt Pjrks Levees [or Dikes) Strategic Retreat Multi-purpose Levees Groins Coastal Morphology Restoration Breakwaters Polders Constructed Wetlands Artificial Reels f * Floating Islands I Breakwaters Constructed Same Islands Surge Barriers Source; DCP Typical Coastal Resiliency Measures nts Structures 25 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Integrated Water Management Example 2-2 Integrated Living Water System (New Orleans, LA) Source: http://livinawithwater.com/Dlan/ The Integrated Living Water System offers an innovative approach to water management and is inspired by techniques used by the Dutch. The system is a "model for managing stormwater, surface water, and ground water collectively, rather than as isolated phenomena" by using small scale retrofits, circulating canals, strategic parklands, integrated wetlands, integrated waterworks, regional monitoring networks, and waterfront development zones. The goal of this approach is to slow, store, and use stormwater in order to reduce the region's dependence on pumping. The systems are adaptable, site specific, and can be tailored to scale.

RETAIN " * STORE " " DRAIN *' ¦ . 28 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Slow, Store, Drain, and Circulate & Recharge are the practices and strategies that comprise the toolbox of the Urban Water Plan and are defined and discussed in more detail in the Plan's System Design report. Some are familiar and widely used, while others are specific and unique to this project. Familiar practices are listed and illustrated in this section without definition, while specific strategies are illustrated and briefly described. Slow "Slow" strategies, otherwise known as stormwater best management practices (BMPs) or green infrastructure, include rain gardens and bioswales, trees and plants, pervious paving, green roofs, and water harvesting. Relatively small in scale compared to store and drain measures, these practices can have significant impact when distributed over a large area. Increasingly popular in recent years, these strategies capture and infiltrate rain where it falls, thus delaying the water's journey to drainage systems and reducing polluted stormwater runoff. Long-term green infrastructure plans are in use in numerous cities around the country, including Philadelphia, Portland, Ore., Seattle, Milwaukee, New York, Syracuse, NY, and Washington, DC. These and other case studies [a few of which are included in Appendix D) have shown that implementation of these practices relies largely on local actions. These include establishing strong water retention standards for new development and redevelopment, providing incentives for private parties to reduce existing impervious surfaces and install green infrastructure, a commitment by local governments to incorporate best practices in public works projects, a dedicated funding source, and close collaboration among agencies. Slow GREEN ROOFS TREES & PLANTS RAIN GARDEN BIOSWALE PERVIOUS PAVING WATER HARVESTING Store & Use Generally larger in scale, "store" measures include both well-known practices like storage basins, constructed wetlands, and subsurface storage, and specific recommendations like widening existing canals and finding space for new canals to store excess water longer in the region's Sample page from the Integrated Living Water System showing Slow strategies and Store and Use measures. 29 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 EXFILTRATION BASINS are a redesign of typical catch basins and manholes found throughout the region. The basins enable water to gradually enter the groundwater system through a pervious bottom and a spread aggregate base. A system of these basins provides for a distributed method of recharging groundwater. IMPROVED CANAL is an existing canal that has been renovated to widen its banks and provide a stepped platform, where possible, that can serve as an inviting public space during dry weather and as extra water storage during heavy rains. This practice of controlled flooding is widely used in the Netherlands. landscape. According to our team's hydraulic model that tested various scenarios, water storage has the biggest impact on flood reduction in the region. These interventions also do more to address subsidence as they allow water to infiltrate the ground and balance water levels. More information on the hydraulic model and its results can be found in the Plan's Water System Analysis report. Store STORAGE BASINS In addition to the action needed for the implementation of strategies that slow down water, the establishment of a stormwater/groundwater management unit in each parish will be key to the implementation of store strategies. Beyond MS4 (municipal separate stormwater sewer systems) compliance, this unit would be dedicated to finding and funding softer and more cost-effective water storage solutions, as well as operating and maintaining them. Drain With the progressive installation of slow and store practices, loads on current drainage systems are reduced significantly, CONSTRUCTED WETLAND SUBSURFACE STORAGE Sample page from the Integrated Living Water System showing Store and Drain measures. REDIRECTED DISCHARGE is a strategy that provides a shorter drainage route by redirecting some of the discharge to the river, the Industrial Canal, and the natural wetlands. This will relieve currently overloaded canals, allow for raised water levels in proposed circulating networks, and contribute to wetland restoration.

The city embarked on a flood control system comprised of a network of landscaped buffers and detention basins. A key part of this comprehensive approach included a city acquisition program to remove structures located in flood-prone areas and convert these areas into open spaces for recreation and stormwater surge. o With financial support from FEMA from the Hazard Mitigation Grant Program and a 25% local match, the city purchases flooded properties after a storm event. o After the 1984 flood to 2004, the city had cleared more than 900 buildings from the floodplain. o Since 1990, more than $200 million has been spent on capital projects and programs with 40% of the funds coming from the federal government. Local funding for flood mitigation comes from a construction sales tax and stormwater fees. There has been no record of flooding in any structure built after 1987 and Tulsa became the first CRS community. Due to its high CRS ratings, residents receive a 40% premium reduction on their flood insurance and have access to recreational amenities.

The Bee Branch Watershed Mitigation Project is a multi-phased investment based on a holistic approach to mitigate flooding, improve water quality, stimulate investment, and enhance the quality of life. The project features daylighting 4,500 feet of buried creek and restoring it and its associated floodplain; creating a linear park along the open waterway; creating parkland along the lower Bee Branch Overlook and incorporating a bio-island, rain gardens, and bioswales; building an amphitheater adjacent to elementary schools; adding biking and hiking trails; planting over 1,000 trees; and adding over six acres of permeable paver alleys and parking lots with the end goal of preventing 2,400 pounds of sediment and 750,000 cubic feet of runoff a year from entering the Mississippi River. The Project has a 12 phase plan: Phases 1-3 are complete, 4 and 6 are under construction, and 5 and 7-12 are under design, using a patchwork of funding from federal, state, local, and public/private partnerships. o Iowa Flood Mitigation Board (IFMB): Created in 2012, charged with creating a flood mitigation program for Iowa. Program will allow certain governmental entities to submit flood mitigation projects to the board for review and possible approval for funding. Funding will come from sales tax increments or appropriations from the General Assembly. o IFMB approved $98.5m for Bee Branch Mitigation Project. The funds will come from a sales tax increment over a twenty-year period per the schedule outlined. Revenue comes from the incremental increase in the state sales tax in the community seeking flood protection funds. o Using a sales tax increment approach, the city provides an average of $5 million in funding yearly and does not exceed $7 million. 33 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Kennedy lie Creek Basin HamiltoryStreet fiasin Carter Road Detention Basin 32nd Street Detention Basin Cloie Branch Basin vStteet Basin B as Bee Branch Basin Bee Branch Creek Restoration Project dartte Ngrth Fork Catfish Creek Basin \ | Peonsylvan'3 _ Ice Harhor ^asi [o x-, MiqdleXodt-Ca@yfc-fe8k.RasjiL Maus Park Basin Middle Fork Catfish Cr^ek Basin Map showing locations for the Carter Road Detention Basin, 32nd Street Detention Basin, and the Bee Branch Creek Restoration Project.

The facility is built on an 11 acre city-owned pier in the South Brooklyn Marine Terminal, making it accessible via barge, rail, or truck. The majority of inbound material accesses the facility by barge from SMR facilities in the Bronx and Queens. The majority will leave via barge and rail, taking thousands of truck trips off of the streets of New York. The site specific plan incorporates multiple innovative elements that promote sustainability and resiliency: o Stormwater is managed on-site using landscape features, bioswales, grading, and a retention pond. o The site has a 600kW solar power installation to generate its own electricity. o The city constructed three artificial reefs to mitigate the effects of the necessary dredging on the site to promote biodiversity. o All of the buildings, high voltage electrical gear, scales, and recycling gear were raised four feet above the new FIRM maps and remained dry during Hurricane Sandy. As a public/private partnership, this facility required a $48 million investment from NYC and a $46 million investment from Sims. o The facility is retained by the city and is currently on a 20 year lease to Sims with the option for a 7-year or 10-year renewal. =,,j f^s-r _ Proposed recycling facility plan. 37 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Site-specific Plans Example 2-6 Metairie's Pontiff Park (New Orleans, LA) Source: http://livinawithwater.com/reports/ Metairie's Pontiff Park highlights successful water management into recreational public spaces. The park's high performance landscape maintains the appearance of a traditional suburban park. The park contains a three foot tall earthen berm that is constructed around the perimeter of the park. The berm creates a 40 acre stormwater retention area that is designed to retain up to 52 million gallons of water for up to a day before being siphoned into the canal system. The community received a FEMA grant of over $3 million for these retrofits. Flooded park area in New Orleans (left), and an example of a leveed basin (right).

The majority of the plant was built in the 1960s and 1970s and the equipment was operating well beyond its designed life. The Center is a secondary wastewater treatment facility that provides screening, grit removal, primary treatment, secondary treatment by the oxygen activated sludge process, final clarifications, and ultraviolet disinfection. Using structural repurposing and an innovative site design, the facility uses anaerobic digestion to break down accumulated biosolids in wastewater, uses the methane produced to produce electricity to power the plant, and safely discharges clean water into the Mississippi River. The plant uses ultraviolet disinfection instead of traditional chlorine. All of the buildings are Energy Star Rated and the landscaping uses elevation and rain gardens to mitigate stormwater runoff. While the upfront costs of the upgrades are high ($64 million), the yearly operating costs are lowered, the lifespan of the plant has been extended 35 to 40 years, and the plant has the potential to become electrically self-sufficient. The City of Dubuque funded the upgrades to the Waste Water Treatment Plant through the Iowa Clean Water State Revolving Fund loan fund, which will be repaid through sanitary sewer fee revenue.

Both of the taxes have lifespans of twenty years and were reauthorized in 2009 and 2010. The taxes generate at least $11 million annually and cost the average household $56 a year. Due to economic growth and population increase, the sales tax is expected to bring in $22 million a year by 2031, resulting in a total income of $312 million over its lifetime. The dedicated funds have funded flood mitigation efforts, buyout programs, and wastewater infrastructure updates. The city has identified $247 million worth of projects and property acquisitions. These projects are divided into five different phases through 2016, to be funded in part by the new tax revenues. A key initial project is the realignment of 2nd Street Flood North to provide additional flood protection for portions of the downtown area and integrate public greenspace and a walking path along the river. The project will replace temporary levees with permanent, reliable protection. The raised revenue from related taxes has been used to remove hundreds of flood-prone homes along the red river. The mixture of buyout programs and levee system upgrades has created more predictable flood scenarios. 3RD STREET N yiB^TREETN Map of proposed additional flood protections in Fargo. 45 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Flood-related Taxes Example 2-12 Sales Tax Abatement Program for Flood Resiliency (New York, NY) Source: http://www.nvcedc.com/proaram/open-industrial-uses-sales-tax-exemption-proaram Provides a tax exemption of up to $100,000 per company on the purchase of building materials used for projects. The sales tax abatement program provides $10 million in sales tax abatements in $100,000 increments to qualifying industrial businesses seeking resiliency retrofits. The sales tax abatement is justified because industrial businesses frequently run on thin profit margins and are clustered along the waterfront. The program will prioritize 1- to 2-story buildings whose ground elevation is more than four feet below the applicable BFE. The program targets industrial businesses with unenclosed or open industrial uses, such as: o Waste recycling facilities, o Scrap metal processors, o Automobile dismantling operations, o Concrete and asphalt manufacturing, o Construction and demolition debris transfer stations, o Unenclosed storage of construction materials. The scope of renovations can include the following: o Improvements to control environmental emissions at open facilities, o Paving, grading, containment walls, storm water management systems, and flood resilient construction. The parameters of the program include the following: o Applicants must commence improvements within one year of receipt of the sales tax letter. o The sales tax letter will expire no later than three years from the date of its issuance. 46 ------- Brownfield Revitalization in Climate-Vulnerable Areas January 2016 Section 3 EPA Climate Adaptation Planning Resources The following EPA resources may be helpful in identifying resources to aid in planning, designing, or implementing climate resiliency measures in brownfields revitalization projects.
