What is CSS not? • Not a product; it is a process • Not just design • Not easy
What does CSS look like? • Understand & define the Context before design begins • Engage, listen & react to communities • Apply flexible designs
How is CSS different? • Involve multi-disciplinary team early • Understand valued resources before designing • Involve stakeholders with open, continuous communications • Balance transportation need with community values • Employ roadway design that is creative, flexible and safe
Design Excellence-Standard Practice Mobility Safety Enhancement of the Natural Environment Preservation of Community Values
Qualities of Excellence in Design • Satisfies purpose & need as defined by stakeholders • Safe facility for user & community • In harmony with the community and the natural & built environment • Efficient and effective use of resources • Minimal disruption to the community • Lasting added value to the community
Define the Context at beginning • Transportation Context • Community Context • Environmental Context
Transportation Context • Functional Classification • System Context: regional or local • Setting: urban, rural, suburban
Community Context • Demographics: community or social groups • Particular characteristics to be preserved or enhanced • Historic features that are valued
Environmental Context • Ecology & wetlands • Cultural resources, including historic sites • Farmland, parkland, etc. • Noise Receptors
What is Purpose & Need? • Seek input from technical team, public officials, focus groups & others. • Seek consensus on problems and needs
Consensus Consensus does not mean that everyone agrees, but that groups and individuals can live with a proposal.
M-463, Jackson, MS Project Goals • Reduce congestion • Existing 2-lane volumes = 1,900 to 19,900 vpd. • Projected = 9,600 to 33,300 vpd • Improve safety (limited sight distance)
M-463 Context • Commercial around interchange • Suburban • Rural • Historic properties • Scenic view-sheds • Major growth potential
M-463 Context Constraints • Development close to roadway • Scenic property close to roadway • Historic properties need to be avoided • Historic Church congregation objects to visual impacts of an “interstate highway”
M-463 Existing Conditions • Plan • Section Church Silo Church
Church Silo Lake Proposed with DOT Criteria • Plan • Section
M-463 CSS Objectives • Save silo and lake with narrower footprint • Reduce visual impact by hiding the new lanes
M-463 Design Considerations • Change the requirement for a 90-ft. median • Change design speed • Accept increased travel time
M-463 Design Considerations Construct the new lane at a lower elevation than the existing roadway
M-463 CSS Results • Preserved view-shed • Citizens and DOT accept increased travel time as a positive trade-off • Citizens gain respect for DOT because it listened to their concerns • Project moves forward at reduced cost
