• Road and storm drain plans for Canning House Road will need to be
approved and a Public Works Agreement will need to be executed prior to
the issuance of building permits for the site.
• Perryman Access Road is identified on the Transportation Element Plan.
In accordance with the Harford County Subdivision Regulations,
Perryman Access Road shall be designed by the developer and
constructed by the County with funds escrowed by the developer as
shown on the preliminary plan from the property line east of Fords Lane
to Canning House Road in accordance with Harford County Road Code
standards.
Required Design Standards
• Harford County Road Code
• Maryland Manual on Uniform Traffic Control Devices (MdMUTCD) 2011
or latest edition (for the pavement striping and traffic control signs.)
Rights-of-way / Easements required
• Drainage and utility easements are required along all stormdrains from
the edge of the right-of-way to the end of the outfall treatment. Easements
shall be shown on final road and storm drain plans and on the subdivision
plat.
• A 30-foot-wide right-of-way dedication is required from the center line of
the road along Ford’s Lane.
Sidewalks
• A sidewalk shall be provided along Canning House Road from Perryman
Road (MD Route 159) to Chelsea Road. The sidewalk as shown on the
site plan along the south side of Canning House Road is acceptable.
• Handicap ramps shall be provided at the time of final design on the road
and storm drain plans at the roundabout at the intersection of Canning
House Road with Perryman Access Road, at the intersections of Canning
House Road with Perryman Road MD Route 159 and Chelsea Road, and
at all entrances to Canning House Road. Handicap ramps shall be
located at the PC/PT of the curb returns.
Drainage
• Suitable outfalls must be provided for the proposed storm drain systems
along Canning House Road and shall be approved at the time of final
design.
Design Comments
• Canning House Road shall be constructed in accordance with the Harford
County Road Code design criteria for Business/Industrial local roads that
specifies a 40-foot-wide pavement on a 60-foot-wide right-of-way with 5-
foot-wide sidewalks on both sides. A modified typical section as shown on
the site plan (from Perryman Access Road to Perryman Road (MD 159))
consisting of a 44-foot-wide pavement on a 60-foot-wide right of way with
5-foot-wide sidewalks on both sides will be acceptable. A modified typical
section as shown on the site plan (from Perryman Road (MD 159) to
Chelsea Road) consisting of a 40-foot-wide open section roadway on a
60-foot-wide right of way with 5-foot-wide sidewalk on one side of the
roadway will be acceptable. Note that no Stormwater facilities, other than
grass swales, will be allowed within the right-of-way.
• Perryman Access Road shall be constructed as a 38-foot-wide open
section roadway on a 60-foot-wide right of way with a 10’ wide trail as
shown on the site plan.
• Perryman Access Road shall be realigned at the intersection of Canning
House Road to align with the proposed roundabout. It is understood that
the alignment of the Perryman Access Road needs to be contained
outside the Forest Interior Dwelling Species Habitat. If the Perryman
Access Road cannot be realigned to align with the roundabout due to the
Forest Interior Dwelling Species Habitat, the roundabout should be
eliminated at the three-way intersection of Canning House Road with the
private entrance road.
• The proposed relocation of Canning House Road and its access point to
Perryman Road (MD 136) is found to be acceptable by the Department of
Public Works.
• Provide a roundabout at the intersection of Canning House Road and
Perryman Road (MD 159).
• Sight line profile has been provided demonstrating adequate sight
distance for Canning House Road at Perryman Road (MD 159). Sight line
profile has been provided for Canning House Road at Chelsea Road.
(MD 159). Harford County comments will need to be addressed on this
sight line profile to ensure adequate site distance for a 45-mph design
speed per AASHTO standards prior to the preliminary plan approval. A
Maryland-T was shown on the sight distance profile provided to Harford
County which addresses the sight line comments and should be shown
on the site plan.
• Curve radii for horizontal alignment of Canning House Road shall be a
minimum of 380’. A design waiver is required if this condition cannot be
met.
• Pavement sections for Canning House Road shall be per Harford County
Business, Commercial and Industrial Roads (Plate R-3).
• Provide a “slip ramp” for traffic making a right turn from Chelsea Road
onto Canning House Road to provide a smoother transition especially for
truck traffic by limiting the stop condition and reducing acceleration noise.
• Private signs at entrances shall be placed so as not to interfere with sight
distance.
• A revised traffic impact analysis was submitted for review. Comments will
be forwarded to Planning and Zoning.
