On November 9, 2017 ACHD received a revised concept plan for the Linder Village project.
The traffic impact study was not updated to reflect the changes to the layout and land uses
proposed on the concept plan. ACHD will need more time to review the concept plan and will
require an updated traffic impact study prior to taking a formal action on the preliminary plat
application. Below is a general list of concerns with the proposed concept plan.
1. The layout and proposed land uses on the concept plan don’t match the submitted traffic
impact study for this project. An updated traffic impact study should be provided to
ACHD for review and approval, prior to ACHD action on the preliminary plat application.
2. The concept plan shows the extension of stub streets into the site, however, they do not
provide a direct connection between the existing residential subdivisions and the
proposed commercial uses on the site. As currently proposed all of the residential traffic
would have to travel on the arterial roadway system via Linder Road or Chinden
Boulevard to access the WinCo Foods and commercial uses on the site.
3. A public street was not previously proposed on the site. The concept plan shows a
public street intersecting Linder Road and extending east to terminate in a roundabout.
The City of Meridian has indicated a desire for an east/west collector roadway to run
between Linder Road and Fox Run Way; this is not reflected in the concept plan. If a
public street is constructed it should be constructed as a collector roadway and extend
between Linder Road to the site’s east property line, allowing it to be extended to Fox
Run Way in the future when the adjacent parcel develops. Front-on housing is
prohibited on collector roadways.
4. An intersection analysis for the proposed roundabout should be included as part of the
updated traffic impact study.
5. The northern driveway on Linder Road doesn’t appear to be necessary to serve the site.
This driveway should be re-evaluated as part of the updated traffic impact study.

6. The concept plan shows a drive aisle just south of Chinden Boulevard extending from
the middle of the site east to intersect Fox Run Way. The location of this drive aisle
where it intersects Fox Run Way would be too close to allow for a full access driveway
onto Fox Run Way, as the Chinden/Fox Run Way intersection is signalized.
7. ACHD is not supportive of the proposed signalized intersection at Bergman Way and
Chinden Boulevard. The original traffic impact study noted that a signal is not warranted
at this intersection if access to Fox Run Way is available, and is not warranted with the
first phase of the development. ITD is planning to pursue conversations with the
adjacent property owner to obtain a public street connection between Fox Run Way and
the Linder Village development site. The signal warrant analysis should be revised to
reflect the new concept plan. If as a result of the updated analysis a signal is warranted
and is allowed by ITD, ACHD won’t allow the installation of the signal until is warranted.
8. ACHD is supportive of the revised main drive aisle, which runs through the middle of the
site instead of directly in-front of the WinCo Foods. However, the first intersection to
provide access to the WinCo Foods should be redesigned to provide a standard “T” type
intersection. The concept plan shows this driveway at an angle, which may cause driver
confusion and sight distance issues. Staff also has sight distance concerns at the
WinCo Foods parking lot, as the parking lot drive aisles are proposed to intersect the
main drive aisle at a diagonal.
9. The concept plan notes that improvements to Chinden Boulevard will be made per a
STARS agreement; however, it is unclear what improvements are actually proposed and
what happens if the improvements are never made. Please clarify and include this
information in the updated traffic impact study.
Please let me know if you have any questions.
Sincerely,
Mindy Wallace, AICP
