FROM: Sharon Eckard, PG
TO: BF Assessment File
RE: Harrington St
413, 437 & 441 N. Harrington Street
Raleigh, Wake County
Brownfields Project # 20031-16-092
Based on the following information, it has been determined that the above referenced
site, whose intended use is for no uses other than as a multi -unit residential, commercial,
and retail development with associated parking, and with potential office or hotel use.
Introduction
The Property is comprised of three tax parcels at 413, 437, and 441 N. Harrington Street
(the `Brownfields Property") in Raleigh, Wake County (parcel IDs: 1704-51-2008, 1704-
51-3220, 1704-51-3430), totaling 2.18 acres. The Property is bordered to the north by
commercial property with a number of tenants including Wood Products, Inc., a custom
cabinet maker, ThemeWorks, a furniture rental service, Southland Ballroom, a music
venue, and N. Harrington Street beyond; to the east by N. Harrington Street with the
Wake County General Services complex and Archer Investment Management, a financial
planner, beyond; to the south by the residential development, West Condominiums with
W. North Street beyond; and to the west by N. West Street with commercial office and
retail stores beyond including L Star Management, a financial planner, and House of
Landor, a vintage clothing store, Cannon Architects, Alan Scott Mae Salon, and Still Life
Raleigh, a night club, and a paved parking area.
Redevelopment Plans:
The Prospective Developers (co-PDs) are Harrington Street Partners, LLC and
Harrington Street Acquisition Partners, LLC, which are owned and managed by Gregg
Sandreuter, a known real estate developer in the Triangle. PD wishes to redevelop the
property into multi -unit residential apartments. All three parcels (413, 437 and 441 N.
Harrington Street) were developed with office buildings, originally constructed in the
mid- to late 1960s, with asphalt -paved surface parking, concrete walkways and
landscaped areas. These structures will be demolished to make way for the
redevelopment.
Site History:
The Brownfields Property was initially developed as single family residences from at
least 1914 to 1959. Around 1965, as part of a downtown Raleigh redevelopment
initiative, the residences were razed. Incorporated into historic deeds circa 1966 for these
parcels were a number of restrictive covenants that prohibited specific uses including

manufacturing, disposal, or residential uses; however, language in the deeds conveying
these parcels from the Raleigh Redevelopment Commission provided for the automatic
termination of these restrictive covenants at midnight, November 6, 1990. Hence, these
restrictive covenants no longer apply. Since that time the primary use has been office
space and associated parking.
Summary of Environmental Conditions:
Chemical use at the Brownfields Property was minimal given its use as residential or
office property; a printer service was located on one of the parcels for a time, but no
environmental concerns have been detected at the Property stemming from that use. Bulk
oil storage facilities and underground storage tank incidents are known within the area,
including hydraulically upgradient of the BF property.
Environmental investigations at the Property consisted of soil and groundwater
assessments in 2004, 2013, 2015 & 2016. Soil was not found to be contaminated at the
Property. An EMP required by the BFA will address handling impacted soil or
unexpected conditions upon their discovery. Only one sample point located near the
upgradient side of the Property had benzene and C5-C8 aliphatic petroleum hydrocarbon
compounds in excess of groundwater 2L standards in 2015. This is suspected of being
the downgradient impact of the releases from the former bulk oil facilities south of the
site.
Potential Receptors:
Potential receptors are construction workers, workers, residents, visitors, and trespassers.
Contaminated Media Summary:
DEQ has evaluated data collected from the following media at the subject property:
groundwater and soil. DEQ relies on the following data to base its conclusions regarding
the subject property and its suitability for its intended reuse.
Soil
Soil was not found to be contaminated at the Property.
Groundwater
Available groundwater results indicated one well location with benzene (4.9 ug/L) and
C5-C8 aliphatic petroleum hydrocarbons (2,400 ug/L) at temporary well TMW-2, in
excess of 2L standards of 1 ug/L and 400 ug/L, respectively.
Surface Water
There is no surface water at the Property.
Soil Vapor
Soil gas sampling was not conducted at the Property due to the limited VOCs in
groundwater, and that for those contaminants detected, the concentrations did not exceed
the applicable residential vapor intrusion screening level (VISL).
2

Sub -Slab Vapor
Sub -slab vapor data were not collected because VOCs were not detected in site
groundwater above residential VISLs.
Indoor Air
Indoor air data were not collected due to the low concentrations of VOCs in site
groundwater.
Risk Calculations
The groundwater data were evaluated using a groundwater risk calculator (Jan. 2016)
provided by Sandy Mort, BF Toxicologist. The resulting calculated risk ranges for cancer
effects and non -cancer effects in a non-residential setting indicate a lifetime incremental
cancer risk of 3.1E-06 and a hazard index of 0.0355, which are within an acceptable
cumulative risk range and under a hazard index of 1.
Required Land Use Restrictions —
Land use restrictions will include the standard Environmental Management Plan,
groundwater, soil disturbance, and known contaminants LURs. Due to the low
concentrations of VOCs in onsite groundwater, and resulting risk calculator results, the
vapor mitigation system LUR is not included.
Based on the site -specific data provided to the Brownfield program, the site reuse is
suitable for the site as long as the agreed upon land use restrictions in the BFA are abided
by.
