PURPOSE:  The purpose of the Midcounty Corridor Study (MCS) is to develop transportation improvements in Montgomery County east of I-270 between Clarksburg and Gaithersburg.  These improvements are designed to: relieve projected congestion on roadway facilities between Clarksburg and Gaithersburg, east of I-270; provide a north-south corridor which improves the safety and efficiency of short and moderate length trips in the study area; improve vehicular, pedestrian, and bicycle access to residential, commercial, and employment destinations in Clarksburg and in the eastern areas of Gaithersburg and Germantown; be implemented in an environmentally sensitive manner using measures to avoid, minimize, and mitigate impacts.



LOCATION:  The Midcounty Corridor Study area is bounded by I-270 on the west, I-370 and the Intercounty connector (MD 200) on the south, Snouffer School Road and Wightman Road on the east and Snowden Parkway on the north.  Alternatives examined within the project study area cross Great Seneca Creek and its tributaries including Cabin Branch, Walkers Run, and Whetstone Run.      


WORK:  For the Midcounty Corridor Study, MCDOT has studied six alternatives, including a no-build alternative, and three northern terminus options.  All the build alternatives include the following design elements: a design speed of 40 miles per hour; a divided highway with a minimum of four through lanes; a five-foot wide sidewalk and ten-foot wide shared use path; and on-road bicycle facilities (where recommended in the Countywide Bikeway Network Concept Plan).  The six alternatives retained for detailed study are:


Alternative 1-No-Build.  The No-Build alternative serves as a baseline condition for comparison of the other (build) alternatives.  The No-Build alternative assumes that all programmed transportation improvements within the study area are completed by the year 2030 except for the extension of the Midcounty Highway.


Alternative 2-Transportation System Management/Travel Demand Management (TSM/TDM).  TSM/TDM improvements, low cost intersection improvements that could be constructed within the existing right-of-way, are proposed for 16 intersections in the study area.


Alternative 4 Modified-Brink/Wightman/Snouffer School/Muncaster Mill.  Alternative 4 Modified would be a 7.5-mile widening of Ridge Road, Brink Road, Wightman Road, Stouffer School Road, and Muncaster Mill Road.  Ridge Road (MD 27) between Snowden Farm Parkway and Brink Road would be widened from a two-lane undivided roadway to a six-lane divided roadway.  Between Ridge Road and Shady Grove Road, the existing corridor would widen from four to six-lanes of divided highway (i.e., four lanes north of Montgomery Village and six lanes south of Montgomery Village).  Existing Midcounty Highway from Goshen Road to Montgomery Village Avenue would be widened from a four-lane divided highway to six-lane divided highway.


Alternative 5-MD 355 with Service Roads.  Alternative 5 is a 6.6 mile route that follows Ridge Road, Frederick Road, Montgomery Village Avenue, and the existing Midcounty Highway.  Ridge Road would be widened from a two-lane undivided roadway to a six-lane divided roadway.  From Ridge Road to Middlebrook Road, MD 355 would be widened from a four-lane divided highway with auxiliary turning lanes to a six-lane divided highway with auxiliary turning lanes and a service road at some locations.  From Middlebrook Road to Montgomery Village Avenue, a service road would be added to MD 355 at some locations.  Montgomery Village Avenue between MD 355 and Midcounty Highway would have the existing sidewalk replaced with a shared use path.  Existing Midcounty Highway from Montgomery Village Avenue to Goshen Road would be widened from a four-lane divided highway to a six-lane divided highway.


Alternative 8-Master Plan Alignment Truncated at Watkins Mill Road.  Alternative 8 would follow the Master Plan alignment from Snowden Farm Parkway to Watkins Mill Road as a four-lane divided highway.  Alternative 8 would include one of three Northern Terminus Options described below.  Alternative 8 would include intersection improvements along Watkins Mill Road and MD 355.  It would widen the existing Midcounty Highway to a six-lane highway between Goshen Road and Montgomery Village Avenue, and widen Middlebrook Road to a four-lane divided highway from Midcounty Highway to MD 355.


Alternative 9-Master Plan Alignment.  Alternative 9 is a 5.7 mile route that would follow the Master Plan alignment from Snowden Farm Parkway to Montgomery Village Avenue.  Alternative 9 would include one of three Northern Terminus Options described below.  From Snowden Farm Parkway to Montgomery Village Avenue, Alternative 9 would be a four-lane divided highway.  Alternative 9 would widen the existing Midcounty Highway to a six-lane divided highway between Goshen Road and Montgomery Village Avenue.  Middlebrook Road would be widened to a four-lane divided highway from the Midcounty Highway to MD 355. 


Northern Terminus Option A.  Northern Terminus Option A would be a four-lane divided highway from Ridge Road to Watkins Mill Road.  Option A would intersect Brink Road and cross through North Germantown Stream Valley Park, Seneca Crossing Local Park, Dayspring Church Silent Retreat Center, and All-Souls Cemetery.


Northern Terminus Option B.  Northern Terminus Option B would cross North Germantown Stream Valley Park.  At Brink Road, Option B would follow Brink Road to Ridge Road.  Brink Road would be widened to a four-lane divided highway.


Northern Terminus Option D.  Northern Terminus Option D would be a four-lane divided highway that shares the same alignment as Option A through North Germantown Stream Valley Park.  After crossing Brink Road, Option D would bisect the former Benson-Sibley farm property and the Woodfield Farm property.  Option D would cross Wildcat Road and All-Souls Cemetery.             


As proposed, Alternatives 8 and 9 would completely avoid wetland and stream impacts at Dayspring Creek and Brandermill tributary using a bridge crossing.  Alternatives 8 and 9 would also span both the primary and secondary channels of Seneca Creek.  Alternative 9 would cross Whetstone Run north of Watkins Mill Road on a proposed 230-foot bridge.


Impacts to nontidal wetlands and streams from the six alternatives range from 0–0.87 acres of permanent nontidal wetland, 0–1,035 linear feet of permanent perennial/intermittent stream, and 0–247 linear feet of ephemeral stream impact.  The alternatives would convert between 0–1.70 acres of forested nontidal wetland to emergent nontidal wetland.  Alternative 9 would relocate approximately 746 linear feet of perennial/intermittent stream and 243 linear feet of ephemeral stream.  Build alternatives 4 Modified, 5, 8 and 9 would impact between 0.4-4.8 acres of floodplain and 0-0.99 acres of nontidal wetland buffer.  All temporary impacts to wetlands and streams would be restored upon completion of the project.  A comparison of potential wetland and stream impacts by each alternative is attached.  Section 2 of Draft EER provides additional information on the five build alternatives and their potential impacts. 


As part of the planning process for the proposed project, steps were taken to avoid and minimize impacts to waters of the United States, including jurisdictional wetlands, to the maximum extent practicable.  Additional avoidance and minimization measures may be required as a result of future Corps/MDE actions and determinations including comments received during the Public Notice comment period.  Impacts are proposed to be avoided and minimized by bridging, alignment shifts, reducing road cross section width, and use of retaining walls, wherever practicable.  Any unavoidable permanent impacts to wetlands and streams would require compensatory mitigation.


The applicant is developing a preliminary mitigation plan based on the needs of the various build alternatives.  A stream restoration site has been identified on North Creek, in Great Seneca Park.  The site is located north of Watkins Mill Road, upstream of the confluence with Seneca Creek.  The proposed stream mitigation would re-grade a segment of channel to create a bank-full bench abutting the stream channel.  The project would increase the frequency of out-of-bank flows and reduce the erosive forces along the streambanks.  The bank-full bench would also be planted with native shrub species.  A wetland mitigation site along Seneca Creek in Great Seneca Park has also been identified.  The proposed wetland mitigation site, SC-21, is located in Great Seneca Park, north of Wightman Road.  SC-21 has the potential for the creation of approximately 1.5 acres of palustrine forested nontidal wetlands in the floodplain of Seneca Creek.  Final design of the stream and wetland mitigation sites will be developed once a Preferred Alternative is selected by MCDOT.   


The Draft EER has been prepared by MC DOT to evaluate the impacts of the project alternatives.  The Draft EER is available for viewing on the Montgomery County project website at: and at the following public locations (to maintain accessibility for all persons, this document is not available for check out):
