COST ANALYSIS

  • Cleaned and scoped storm system.
  • Possible re-grading to improve drainage fmow
  • Low-height street trees are added where there

is room.

  • Solutions will be less expensive, but lack

signifjcant impact in addressing community concerns. Additional Street Trees: 20-30 Trees $10,000 - $15,000 CCTV of existing stormwater system: $8,000 - $15,000 Grading work cost would require further study in specifjc areas where new grading is needed and is achievable.

  • Complete road reconstruction includes

lowering road height to help with drainage.

  • Curb and gutter added
  • Catch basins, new stormwater pipe
  • Tree lawn, new street lights, and sidewalk

added to both sides.

  • Utilities moved below grade.

Lowering the road is only feasible if a suitable drainage outlet exists at a low enough elevation. Further investigation is needed to ensure feasibility.

a multi-purpose path for bicyclists and pedestrians. Lowering the road is only feasible if a suitable drainage outlet exists at a low enough elevation. Further investigation is needed to ensure feasibility.

  • Reconstructed alley to ensure consistent width

and alignment.

  • Allows for emergency safety access to

structures in rear of property

  • Drainage system installed in center of alley to

aid in draining the rear of properties.

ALLEY RUNOFF CONVEYANCE

  • Alley drainage system will aide in the drainage

issues in the rear of the properties on north side of Rings Road.

  • Plan for drainage system includes connecting

into the Ballantrae inlet and detention pond.

  • This would require approval from the

City of Dublin.

TRAIL MOBILITY

  • Alley path would serve as the primary bike and

pedestrian connection for Amlin.

  • The path would connect with the trail from

Ballantrae that ends in Amlin behind the former Pizza shop.

  • The alley path has potential to make additional

connections to the east via the sidewalk network at Churchman Road or the planned bike connections south of Rings Road as a part

  • f the future trail planning done by the City of

Dublin.

RINGS AND COSGRAY ROADS CURRENT ISSUES

  • Intersection at Rings and Cosgray has been a

concern of residents in the area recently due to increased traffjc resulting from the nearby development.

  • Concerns included higher traffjc volumes,

higher speeds, and perception of a lack of safety.

CONCEPTUAL RENDERING OF RINGS AND COSGRAY ROADS ROUNDABOUT SOLUTION

COST ANALYSIS Approximate Project Cost: $2 Million Not including engineering/design, permit, easement/land acquisition and construction phase services.

  • Roundabout is a more compact solution than a

signalized 4-way intersection.

  • Roundabout would increase the effjciency and

safety of this intersection while providing traffjc calming.

  • The alignment of the roundabout was careful

to minimize the impact on private properties, however, two residential properties east of Cosgray would be impacted.

  • The diagram at right is a depiction of a possible

roundabout design for the intersection. This design has not been approved and should be studied more in the future.

STREET TREES

  • Need to be low in height when mature due to overhead utilities.
  • Possible Tree Species:
  • Trident Maple
  • River Birch
  • Zelkova
  • Approximate Cost: $10,000 - $15,000

20-30 Trees

COMMUNITY SIGNS

  • New signage to better create an identity
  • Gateway neighborhood/community signs
  • Allowance: Approx. $5,000

TREE REMOVAL AND LANDSCAPING CLEAN-UP
