Carroll Creek Park & Downtown FrederickCourt Street through East Patrick StreetFrederick, MD 21701
The site is located along a 1.3-mile stretch of Carroll Creek in the City of Frederick’s downtown district. The Creek is a tributary of the Monocacy River, which drains to the Potomac River. The creek flooded and caused extensive damage to the downtown district in both 1972 and 1976, which spurred studies, a Master Plan and Implementation Strategy, the Carroll Creek flood control project, modification of Carroll Creek Park to serve as the roof of the flood control conduits, channelization of the stream, and ultimately, redevelopment of the downtown Carroll Creek watershed area that was previously underutilized due to floodplain constraints to enhance the park.
Several types of industrial/hazardous substance operations including: limestone quarry; unregulated disposal facility; recycling for building materials (including limited quantities of paints and stains); gas station; auto body shops; manufactured gas plant; cannery; cabinet manufacturing; spoke manufacturing; railroad repairs; coal storage; and stockyard were conducted as early as the 1800s in the areas adjacent/proximate to the creek. Contaminants present in hazardous substances were likely used at the properties due to these historical operations and would have included: petroleum from gasoline and heating oil; volatile organic compounds (VOCs)and semi-volatile organic compounds (SVOCs) from coal tar and paints/stains; lead from gasoline; and other metals from autobody shop, railroad, and manufacturing operations.
Environmental assessments were conducted at several of the adjacent/proximate properties between the mid-1990s and early 2000s. Contaminated soil and groundwater was identified at several properties. Various types of contaminants were detected in the area. Several of the properties enrolled in the Maryland Department of the Environment’s (MDE) Voluntary Cleanup Program (VCP) during these environmental assessment and investigation activities; however, several properties withdrew from the VCP. Several other properties completed Response Action Plans for remediation, which were approved by MDE, who subsequently issued closure letters for these properties (deeming the properties safe for occupation/use), with stipulations for land use restrictions and required engineering controls based on the level and type of contamination remaining on-site after the cleanup.
The flood control project was financed through a cost sharing agreement between the City of Frederick (34%), Frederick County (21%), and the State of Maryland (45%). The United States Environmental Protection Agency (EPA) provided funding to MDE between the mid-1990s and 2008 to conduct brownfield site assessments. Several properties described above were initially assessed by MDE under this federally-funded program. The City of Frederick and Frederick County both enacted Brownfield Revitalization Incentive Program (BRIP) legislation to allow brownfield properties in their jurisdictions to be eligible for tax incentives. The City was awarded a $3 million grant from the Maryland Transportation Enhancement Program (TEP) to assist with Carroll Creek Park construction costs. In addition, funding sources for the flood control project included Community Development Block Grant funds, Army Corps of Engineers funds, Maryland Department of Natural Resources Program Open Space funds, local funding, and flood control funding.
The total flood control project cost was estimated to be about $60 million. The Carroll Creek Park project cost is estimated between $10.2 and $20 million.
The creek and creekside now serve as the connection between Carroll Street Park and the downtown district and engage the public’s use with a pedestrian and bike path, bridges, brick-paved pathways, fountains, sculptures, planters, and landscaping.
The creek flood control project, including development of Carroll Creek Park, and planning efforts removed 134 land acres and 400+ buildings from the flood plain, spurred large-scale investment and redevelopment in Frederick’s downtown to transform the once industrial and flood prone area into a service/retail/office/residential use area and tourist attraction. The area now includes office space, retail space, parking decks, multi-family residential units, new jobs, and hundreds of millions of dollars in private investment. In addition, the State of Maryland extended commuter rail service into the downtown area adjacent to Carroll Creek. Additional development is on the way to the creekside, including a mixed-use retail and residential complex.
