Combined Sewer System Issues

CHALLENGE: Areas of Hoboken lie below high tide. The combined sewer system cannot empty out by gravity during high tide, overflowing and causing flooding in the lowest elevation areas in the City.

Coastal Flooding Threat Increases with Sea Level Rise

Sandy Impact 500 million gallons of water = $500+ million in damageMajor hurricane impacts NJ every 5-6 years

FEMA estimates a 26% chance of Sandy like flood in next 30 years(That’s two coin flips over the lifetime of a mortgage)

Incorporating Delay/Store/Discharge into Development

Delay: Green Roof Incentives• Zoning Code changes incentivize green roofs• Applications for more than 10,000 sf of green roofs

approved in 3 months

Delay: Rain Barrels• Amended Code to allow rain barrels• Hosted Rain Barrel Installation Workshops and

distributed 40 rain barrels to participants

26

Incorporating Delay/Store/Discharge into Redevelopment Plans

Hoboken Yards Redevelopment PlanAdopted December 2014• Stormwater and sanitary sewer pumps to serve

this property will be installed by the redeveloper.• Sanitary sewer and storm sewer for the site will

be separated.• All elements of the project shall be in compliance

with the City’s Flood Damage Prevention Ordinance. A varied mix of stairs, seating levels, irrigated green walls may need to be incorporated to tie the street and sidewalk grade to the interface of the buildings on the project site due to this compliance requirement.

Western Edge Redevelopment PlanAdopted August 2015• Rebuild by Design recommended for the Western

Edge area to have a linear park with flood storage. This requirement has become the centerpiece of the Western Edge Redevelopment Plan.

• All new construction and substantial rehabilitation shall also comply with the Hoboken Flood Damage Prevention Ordinance.

27

Incorporating Delay/Store/Discharge into Redevelopment Plans

Neumann Leathers Redevelopment PlanAdopted December 2015• This Rehabilitation Area, covered entirely by

buildings, surface parking, roads and sidewalks, is within the City’s most vulnerable flood zone and is an old industrial site. It is unique in that the buildings with substantial historical character will be retained and improved as a part of this Plan.

• The Plan will mitigate against flooding by incorporating green infrastructure as well as vegetation to the greatest extent within and around the development, including along sidewalks, rooftop gardens, green roofs and walls, decks, and in the courtyards and open spaces to be created.

• All new construction and substantial rehabilitation shall comply with the Hoboken Flood Damage Prevention Ordinance, Chapter 104 of the Hoboken Municipal Code.

28

Incorporating Delay/Store/Discharge into Redevelopment Plans

Southwest & North End Redevelopment PlansInitiating the Planning ProcessHoboken is embarking on the planning process for redevelopment plans for both the Southwest Rehabilitation Area and the North End Rehabilitation Area. As these plans are developed, the same principles will be incorporated to address flood damage prevention, stormwater management, and flood mitigation.

29

Incorporating Delay/Store/Discharge into Redevelopment Agreements

Lorien Lofts Redevelopment Agreement

Delay/Store • Passive House construction –

self sustaining electricity production, building is fully operational in power outage and may eventually connect to future City microgrid

• On-site storm water detention• Low flow fixtures to reduce

amount of sanitary sewer in system

• Green roofs and rainwater capture and reuse

• Flood proofed building to allow for rescue accessibility during flooding

30

Bijou 7th and Jackson Redevelopment Agreement

Delay/Store

• 2 acre park negotiated to be constructed by redeveloper

• 300K gallons of underground storm water detention

• Low flow fixtures to reduce amount of sanitary sewer in system

• Green roofs to be installed on building

Incorporating Delay/Store/Discharge into Development and Redevelopment

Infrastructure Trust FundHoboken is pursuing an option with the State to create an Infrastructure Trust Fund. The concept is for contributions from redevelopers and developers to be collected into this trust to be used for designated infrastructure resiliency projects.• Protecting people that are closer to the water

that might not benefit from an in-land Resist protection measure per Rebuild by Design.– Help elevate mechanicals in those

buildings.– Install wet floodproofing/dry

floodproofing measures per the City’s newly adopted Design Guidelines.

• Contributions from developers may go toward additional Delay/Store components such as rain garden construction and underground storage measures.
