1 93 DALLAS COUNTY PUBLIC WORKS January 12, 2011 MEMORANDUM TO: Commissioners Court THROUGH: Maurine Dickey, Commissioner District No. I FROM: Alberta L. Blair, P.E. Director of Public Works SUBJECT: MCIP PROJECT NORTHAVENINORTH-CENTRAL LINK BACKGROUND In partnership with the City of Dallas on the Northaven Trail portion (Preston Road to White Rock Creek Trail) of MCIP 10221, NorthavenINorth-Central Link, a route alignment study will be completed by Dallas County for the eastern extension segment from Valleydale Drive to White Rock Creek Trail tying into what will be the "Low 5" trail junction. Eventual construction of the eastern extension segment will serve as the match to the City of Dallas led segment from Preston Road to Valleydale Drive. The implementation of this Major Capital Improvement Project (MCIP) was authorized by Court Order dated January 19,2010 which approved specified projects including MCIP project that will be known as NorthavenINorth-Central Link and will be allocated an overall amount of$2,500,000. For the Northaven Trail portion of this project the City of Dallas is designing and constructing from Preston Road to Valleydale Drive, while Dallas County will be designing and constructing the connecting eastern extension segment from Valleydale Drive to White Rock Creek Trail. This City led segment has completed design and will begin eonstruction later this spring. The County led segment also involves a study to identify the most viable and preferred route that best connects to White Rock Creek Trail by traversing potential barriers which include White Rock Creek and possibly both US 75 and a DARTlight rail line. The prime consultant for this study will be Urban Engineers Group, which is an approved IDIQ consultant firm. Urban Engineers Group has assembled a team of sub-consultants that strongly complements the expertise their firm possesses from developing the engineering plans for other high-profile trail projects such as segments III, IV and VI ofkaty Trail. This expertise is critical to delivering a high-quality report considering the connection to White Rock Creek Trail will facilitate vital links with two other nearby trails (Cottonwood Trail and the future Veloway). 411 Elm Street, 4th Floor Dallas, Texas

2 94 Commissioners Conrt January 12,2011 Page Two The eventual junction of these trails, all within less than one mile of each other, has been referred to as the "Low 5" because it will provide users with five directions of non-motorized travel as an alternative to mot0l1zed traffic on the nearby "High 5" US 75/1-635 highway interchange. The overall NorthavenlNorth-Central Link project, MCIP 10221, involves two intersecting segments that will fulfill a need for improved bicycle/pedestrian connectivity in north central Dallas and begin fonning an important east-west route identified on the NCTCOG Regional Veloweb crossing a majority of northern Dallas. SCHEDULE Route alignment study Design Construction FY 2011 FY 2012 FY 2013 STRATEGIC PLAN COMPLIANCE In seeking to provide regional mobility and improved air quality by partnel1ng with Dallas County cities to develop these important infrastructure improvements, Dallas County is remaining consistent with the County's overall Strategic Plan; and in particular is directly fulfilling the following vision statements: Vision 1 Vision 4 Vision 5 Dallas County is a model interagency Partner Dallas County proactively addresses critical regional issues Dallas County is the destination of choice for residents and businesses.
