Motivation for Redevelopment: The former Allied
Leather Tannery is in Penacook a village within the
City of Concord, Nil. Penacook is located along a
natural drop in the Contoocook River, which allowed
for the construction of water-powered mills in the 1800s. Until
the 1950s, Penacook was a prosperous industrial community with
a thriving neighborhood shopping center. Since then. Penacook's
economy lias declined as industrial uses moved out and the
downtown commercial district failed to adapt to a car-centered
lifestyle.
The City of Concord has embarked on a targeted redevelopment
effort for Penacook, built around enhancing the existing
downtown area to meet more of its users needs. Located near
downtown Penacook, 4 Crescent Street had significant
redevelopment potential, but was hindered by environmental
challenges associated with its former uses.
Property History: The 4 Crescent Street parcel lias an industrial
history dating back to the mid-1800s. From 1846 through 1930,
the property housed warehouses to support the Penacook textile
mill, located on an adjacent parcel. In the 1940s, following the
collapse of the textile industry, the mill and surrounding
properties were sold to the Allied Leather Tannery, which
converted the complex to a tannery operation. To support this
use, a wastewater treatment plant, pump house, and coal-fired
electrical generator were built on the 4 Crescent Street parcel.
The tannery went bankrupt in 1987. and the property was then
acquired by a local entrepreneur who was ultimately unable to
redevelop the site. In 2006, the City purchased the property to
support the redevelopment of the adjacent mill building.
The former uses on the Crescent Street property resulted in
environmental contamination. Site investigations determined that
the site had been used for disposal of leather scraps, which were
contaminated with chromium. As the buried leather decayed, it
produced methane, posing an explosion risk and potential vapor
intrusion and structural problems with new construction. Other
soil contamination included arsenic and polycyclic aromatic
hydrocarbons (PAHs), likely from the historic use of coal and
asphalt on the site.
Project Results: In 2009, EPA awarded the New Hampshire
Department of Environmental Services (NHDES) a $1.8 million
revolving loan fund (RLF) cleanup grant, funded by the
American Recovery and Reinvestment Act (ARRA). By August
2010, NHDES was able to subgrant $400,000 to the City of
Concord for the cleanup of 4 Crescent Street. Site cleanup
involved removing over 1,000 tons of leather scraps and
associated soils as well as nearly 1,000 tons of PAH-
contaminated soils. The City then sold the parcel to a private
developer, who contributed $2 million to the project. Concord
added an additional $700,000 to make the site redevelopment a
reality.
Construction of a 9,600-square foot office, leased to the Concord
Hospital's Penacook Family Practice, began in June 201 Ion the
Crescent Street parcel. The benefits of this project are
widespread. The cleanup and construction efforts provided over
50 jobs during a difficult economic climate while the new
medical office will retain 26 jobs and create 7 new jobs for the
Penacook community. The project also returns a vacant,
underutilized parcel to a productive community use, signaling a
renewed investment in downtown Penacook while creating a new
tax base for the City of Concord. Phase two of the project plans
to build on these successes, adding an additional 5,500 square
feet of office space to the complex,
