Frederick Memorial Hospital Stormwater Pump Station

Location: Frederick, Maryland

Project Description:

• As part of the $60 million project 2000 renovation the new hospital loading dock created an area which sits below the existing street grade and below the existing storm drain. This created the need to pump the stormwater runoff from the roof and loading dock area to a receiving system.

• Fox & Associates, Inc. designed a duplex submersible storm drain pump station to serve the Frederick Memorial Hospital expansion.

• The pump station was designed to safely convey the ten (10) year storm event of 2,200 GPM.

• Pump station was designed with backup power provided by the Hospital generators.

• The pump station is located within the loading dock area and had to be designed to handle HS-20 traffic loading.

Quail Run Water Distribution and Treatment System

Location: Myersville, Maryland

Project Description:

• Fox and Associates, Inc. developed improvement plans for the construction of approximately 2,500 L.F. of new 2” and 3” raw water main and over 5,300 L.F. of 8” and 12” potable water distribution mains located in Myersville, Maryland. The facilities are located in an upscale residential development known as Quail Run. The wells and treatment facility have been developed in order to supplement the existing water system operated by the Town of Myersville. The site topography is generally rolling to steep, which is typical to Frederick County.

• The raw waterlines which are primarily located in the floodplain area of Quail Run deliver ground water from three (3) different wells to the water treatment plant. The water treatment plant, which was designed by McCrone, Inc. provides green sand filtration and chemical disinfection for approximately 27,500 gpd. After the water is treated, it is directly injected into the water distribution system eliminating the need for a on-site storage tank, while providing additional domestic and fire flows to the subdivision. Fox provided extensive project coordination/management with the Owner, McCrone, Inc., and Review Agencies throughout the design process to coordinate the site planning for the Treatment Plant as well as planning the utility sizes and connection locations. Both the Water Treatment Plant and the water system will be owned by the Town of Myersville.

• Since the wells are primarily located in the 100-year floodplain of Grindstone Run, Fox & Associates also successfully obtain construction permits from the Maryland Department of the Environment and the Army Corp of Engineers for two stream crossings and floodplain construction. While we were able to avoid any wetland impacts, permitting for floodplain construction as well as two stream crossing was necessary. Fox & Associates successfully obtained construction permits from the Maryland Department of the Environment and the Army Corp of Engineers.

Saber Ridge

Location: Myersville, Maryland

Project Description:

• Fox & Associates, Inc. developed improvement plans for the construction of approximately 2,700 L.F. of 6” and 8” potable water distribution mains located in Myersville, Maryland. The facilities are located in an upscale residential development known as Saber Ridge. The development is served by a production well developed in order to supplement the existing water system operated by the Town of Myersville. The raw waterline located within the development area of Saber Ridge delivers ground water from the well to the water treatment plant. Water treatment is provided by the existing Town facility. The water booster pump station designed by McCrone, Inc. was integrated into the existing water treatment building and provides a pressure zone to serve the Saber Ridge development and surrounding residences.

• Fox provided extensive project coordination/management with the Owner, McCrone, Inc., and Review Agencies throughout the design process to coordinate the site planning for the Booster Station as well as planning the utility sizes and connection locations. Both the Water Booster Station and the water system will be owned by the Town of Myersville.

Tuscarora Sewer Interceptor

Location: Frederick, Maryland

Project Description:

• Fox & Associates, Inc., prepared an alignment study and subsequently developed improvement plans for the construction of approximately 8,000 L.F. of large diameter interceptor sewer by Frederick County, Maryland. The interceptor is located in the north side of Frederick between the Cloverhill and Willow Brook developments. The sewer main is for the purpose of eliminating two existing pump stations located near Poole Jones Road and provide new service to the Tuscarora Creek Drainage area.

Site Considerations:

• The general route follows the banks of Tuscarora Creek upstream from Opposumtown Pike to it’s confluence with an unnamed tributary No. 89. From there, the selected route generally follows the tributary to the pump station located near Poole Jones Road. Due to the proximity of floodplain and wetlands, Fox was tasked initially with preparing environmental studies in order to select the horizontal alignment in an environmentally sensitive manner.

Survey/Engineering Highlights:

• All control surveys were prepared using G.P.S. methods. Topography was prepared by photogrammetry methods and supplemented with field verification of existing utilities and drainage facilities where such facilities were evident. Engineering services included preparation of a hydraulic study to determine line sizes. A previous study performed for the County was provided.

• Data for alternate land uses was input into the previously prepared study to determine final line sizes. Complete contract documents and construction plans were prepared and approved by all permitting agencies.

• The fruition of this project will reduce maintenance costs to Frederick County by elimination of two pump stations. Also, the system provides sewer service for a large, currently undeveloped area in the Tuscarora Creek Watershed.

River Oaks Rechlorination Station/Country Meadows Water Main Extension

Project Description:

• Fox & Associates, Inc. performed all site surveying and Civil Site Engineering Services for the construction of 450 G.P.M. reclamation station and the construction of 2,500 linear feet of 24 inch water main to serve County Meadows, a new 440 bed-assisted Living Facility. The domestic demand from River Oaks and County Meadows was inadequate to provide 72 hour turnover in the nearly one mile long “dead end” water main which necessitated the need for rechlorination.

• Fox services included close coordination with McCrone Inc for site plan preparation as well as submission of the site plan to Frederick County Planning Commission and the State of Maryland Department of Health & Hygiene for review and approval. The water main design included design of a crossing of the Monocacy River. Our design included a phased design using “coffer dams” for dewatering for construction in open trenching of the River bottom. Fox also obtained the MDE / ACOE permits required for the in-stream and floodplain construction.
