August 15, 2020

During the August 11 Board meeting,  the Trustees received comments and questions about the Amlin Area Improvement Plan from residents in attendance. The Board of Trustees discussed these topics during their Saturday, August 15th annual strategic planning and goal-setting meeting, and adopted the following prioritization for improvements to the Amlin area:

Phase I – Stormwater management.  Prioritize engineering, cost estimates, design and construction for stormwater improvements with our community partners (Franklin County Engineer and City of Dublin).

Phase II – Sidewalks, streetscape and beautification along Rings Road.  The Board elected to move forward with design of sidewalks north and south of Rings Road, east of the railroad tracks to the Churchman Road roundabout.  Sidewalks will be the narrowest allowed in compliance with the Americans with Disabilities Act (ADA).  The Board also asked the consultants to study the feasibility of adding a sidewalk, or shared use path, on the north side of Rings Road west of the railroad tracks to Cosgray Road.

Phase III – Amlin Alleys.  After evaluating comments and feedback from residents, the Board has elected to leave all alley access points that currently exist.  Grading, asphalt, and stormwater runoff will be improved to the existing township right-of-way alleys.

Meeting Minutes


July 14, 2020

Rings Road Storm Water between Cosgray Road and CSX Railroad: A portion of the storm sewers on Rings Road were cleaned and televised by EMH&T last Spring. Dublin has recently cleaned additional sewers along Cosgray Road south of Rings Road to remove roots and debris. The Township is coordinating with City of Dublin and Franklin County Engineer’s Office to evaluate additional maintenance activities and to identify potential long term improvements including replacement of storm sewers in the area.

Improvements to Rings Road from CSX Railroad to Churchman Road: The Township’s consultant team of EMH&T and MKSK are studying the feasibility of reconstructing Rings Road. The current concept includes adding sidewalks, lowering the road to improve roadside grading, and replacing storm sewers. The limits and widths of sidewalks along Rings Road are currently being studied.

Representatives from EHM&T will provide a project progress report at the June 9 Trustee meeting. The following documentation supports this presentation:

1)      Memo summarizing the CCTV process and findings (this includes the map)

2)      Gateway signage concepts

3)      Concept for improving aesthetics of the stormwater feature at 6923 Rings Road


January 2020

Notification to Amlin residents of township’s plans to conduct preliminary engineering services during the months of February and March 2020. Supporting documentation which will be discussed at this meeting include 1) Memo summarizing the CCTV process and findings (this includes the map which we reviewed on Tuesday; 2) Gateway signage concepts; 3) Concept for improving aesthetics of the stormwater feature at 6923 Rings Road


December 2019

During the first two weeks of December, engineering firm, EMH&T, will begin (1) assessing the physical condition of Amlin’s stormwater drain tile system and the connectivity of septic system connections and (2) identifying the extension of the drain tile system between Cosgray and the railroad tracks.


November 2019

Letters sent to Rings Road residents notifying them of engineering work that is scheduled for December (see below).


October 2019

MKSK began their work on August 2, 2019 and completed it on October 22, when MKSK representatives delivered a presentation to Township Trustees. The delivery of this report concludes Phase 1 of the Amlin area improvement plan. Trustees are in the process of reviewing the report in preparation for further discussion about the study’s findings and recommendations.

In July 2019, The township contracted with MKSK to conduct an initial assessment of the area to collect data about the area’s existing infrastructure, stormwater management, property maintenance, zoning, and resident safety, and propose planning-level recommendations for the Trustees’ consideration.
