DIFFLEY MARKET PLACE — ACCESS ISSUES
BACKGROUND
On October 6, 2005 the City Council considered an application for a Preliminary and
Final Planned Development for a commercial development referred to as the Diffley
Market Place, generally located south of Diffley Rd (Co. Rd. 30) and east of Lexington
Ave. (Co. Rd 43). The Preliminary Planned Development was approved with many
conditions, one of which required that "the driveway connection to Daniel Drive shall be
eliminated and the plans resubmitted to Dakota County for review". Because the property
is adjacent to a county road and will have to be platted to accommodate the proposed
development, the Dakota Contiguous Plat Ordinance requires that the plat be approved by
Dakota County.
COUNTY PLAT COMMISSION REVIEW
In accordance with the Council's directive, City staff submitted the developer's site plan
as reviewed by the Council to the County Plat Commission (CPG), which met on Oct.. 31,
2005. After the CPC's consideration of this site plan, they subsequently denied the plan
as submitted with the Council's conditions (Le. full signalized access from Diffley Rd.
and no driveway connection to Daniel Dr). The CPC stated that they may give favorable
consideration to a revised site plan/preliminary plat that reduces the proposed full
signalized access down to a 114 access (prohibits exiting Ieft turns) and maintains the
driveway connection to Daniel Dr. The City would still have to request a variance to the
County's spacing guidelines for this option to be approved by the CPC.
COUNTY STAFF COMMENTS
Follow up conversations with the County Traffic Engineer revealed that the County
would like to see the site plan's internal circulation revised to maximize a more direct
and convenient access to Lexington Ave, thereby minimizing the development traffic's
need to use a Daniel Dr. connection. However, since they also want to minimize the
number of left turns off a county road into the site, they will continue to require that an
internal connection to Daniel Dr. remain to accommodate the local traffic (frorn the
neighborhoods to the south/east).
ATTACHMENTS
• Copies of the referenced 3/4 access configuration and a full access intersection
configuration. Reducing the exiting left turns reduces the vehicle conflict points
by 69% (from 32 down to 10);
• The site plan as submitted to the County Plat Commission (and subsequently
denied)
• County Plat Commission decision from Oct. 31.

PUBLIC WORKS COMMITTEE RECOMMENDATIONS:
1. Appeal the CPC 10/31 denial of the submitted preliminary plattsite plan
modified by the Oct G Council conditions (i.e. full signal access and no Daniel
Dr. connection) to the County's Physical Development Committee.
2. Request the developer to submit a similar site plan layout with a full signal
access and a Daniel Dr. connection with a variance request to the CDC.
3. Request the developer to submit a similar site plan layout, but with a % Diffley
access and a Daniel Dr. connection with a variance request to the CDC for
probable approval.
4. Request the developer to revise the site plan's internal circulation maximizing
access to Lexington Ave., provide a 3/ Diffley access and no Daniel Dr.
connection for reconsideration by the CDC with a request that, if denied, it be
forwarded under appeal to the County's Physical Development Committee
(PDC) for consideration.

952 891 7067 The Dakota County Plat Commission met on October 31, 2005, to consider the preliminary
Fax 952 8917097
dako
vrww co dakota mn us plat of the above referenced plat. The plat is adjacent to CSAH 30, and is therefore subject
to the Dakota County Contiguous Plat Ordinance.
This preliminary plat indicates one full access at CSAH 30 (Diffley Road) to serve the
proposed commercial development, which is located between two other full access points
at CSAH 43 (Lexington Avenue) and Daniel Drive. The Access Spacing Guidelines for
full access off CSAH 30 is one-quarter mule (1320 feet). The current spacing between the
proposed commercial access and Daniel Drive is approximately 050 feet; therefore, does
not meet spacing guidelines and would require a large deviation from the spacing
guidelines from the allowable guideline of right turns only access. While the plat remains
unchanged from the August 8, 2005, submittal, the City indicated that their approval was
based on severing the existing driveway to Daniel Drive, which is located south of Diffley.
Since the first preliminary plat, Plat Commission members have met with school
representatives to understand the school's traffic patterns and concerns with respect to their
access points. The school is located to the north of this proposed plat. The developer has
provided some traffic data to show the amount of traffic the proposal will generate_
Residents along Daniel Drive have shared their thoughts/concems regarding increased
traffic on Daniel through phone discussions and emails to Plat Commission members. The
Plat Commission concurs that doncentrating traffic at Daniel Drive for the commercial
access is not a reasonable alternative_ Further significant Ieft turns at either Daniel or the
development access is problematic.. The development needs to disperse traffic in a manner
to minimize major conflicting moves, primarily exiting left turn trips onto Diffley by better
utilizing shared access driveways and the roadway system to Lexington Avenue.
Based on the assessment of the operation and issues here, the Plat Commission believes it
would be advantageous to allow a large variance to the current spacing guidelines by
permitting the developer to build a three-quarter access at their commercial
entrance/westerly school access and to keep the existing driveway to Daniel Drive for local
residential access, allowing for safe movements into the commercial site while avoiding

trips onto the County road system. The Plat Commission's recommendation to allow a
three-quarter access permits all movements in and right turns out of the development with
restriction to left turns out. Since the traffic study indicated a minimal amount of trips
exiting this site on the west to Lexington, the development's plan will need to be
reevaluated to determine the best configuration to minimize trips on Daniel and best utilize
Lexington for these trips. A variance from the City to the current spacing guidelines will
be required for the three-quarter access.. A permit for this development will be granted for
a three-quarter access to restrict exiting left turns — this permit does not remove the
County's rights and authority with regards to divided highways and median closures in the
future.
The Plat Commission did not approve the preliminary plat as submitted. The Plat
Ordinance includes a variance/appeal procedure. The Plat Commission must first review
the variance request.. Variances must be in writing, received from the municipality and
describe the need for the variance and the unique hardship, The applicant, designated
representative, or a representative from the municipality mutt attend the Plat Commission
meeting and present the facts or conditions upon which the application for a variance is
based. In the event that the Plat Commission denies the variance or imposes conditions for
plat approval, the requesting local unit of government and/or sub -divider can appeal the
recommended action to the County Board Physical Development Committee of the Whole
(PDC).
No work shall commence in the County right of way until a permit is obtained from the
County Transportation Department and no permit will be issued until the plat has been
filed with the County Recorder's Office. The Plat Commission does not review or approve
the actual engineering design of proposed accesses or other improvements to be made in
the right of way. The Plat Commission highly recommends early contact with the
Transportation Department to discuss the permitting process which reviews the design and
may require construction of highway improvements, including, but not limited to, turn
lanes, drainage features, limitations on intersecting street widths, allowance and size of
medians, etc. Please contact Gordon McConnell regarding permitting questions at (952)
891-7115 or Todd Tollefson regarding Plat Commission or Plat Ordinance questions at

Re: Public Works Cmte Mtg Notice - Diffley Market Place Access review
Dear Ms. Westenberg,
As you know, on November 15, the City Council again reviewed and discussed
the access issues regarding the above referenced development in light of the
County's denial of the proposed plat (due to lack of a driveway connection to
Daniel Drive). As a result, the Council directed the matter to the Public Works
Committee for further consideration and requested that a recommendation be
brought back to the full Council on Dec. 20.
The Public Works Committee consists of Council members Mike Maguire (chair)
and Cyndee Fields. They have scheduled this Committee meeting for 4:30 pm
on Monday December 5 in the Engineering Conference Rooms 1 AB at City
Hall. Councilmenber Maguire requested that a notice of this meeting be sent to
you as the representative for the neighborhood. It should be noted that this is not a
public hearing and there is a very limited capacity in the conference room for this
meeting. The County's Traffic Engineer and Developer have also been invited to
help in the discussion of this item.
Enclosed is a coy of the agenda packet that will be reviewed during this meeting.
Please feel free to contact me if you have any questions regarding this information
or the meeting itself,
Sincerely,
Thomas A. Colbert
Director of Public Works

City of Eagan Memo
To: PUBLIC WORKS COMMITTEE MAGUIRE & FIELDS
From: THOMAS A. COLBERT, PUBLIC WORKS DIRECTOR
Date: DECEMBER 2, 2005
Subject: DECEMBER 5th PW CMTE MTG — Additional Information
Upon being notified of the Public Works Committee meeting scheduled for Monday Dec.
5 @ 4:30 pm, I was contacted by Janet Westenberg, 4241 Daniel Dr. and the developer,
John Trautz requesting that some additional information be provided in advance of the
meeting.
Ms. Westenberg called and requested the following information (within Eagan):
1. Are there any other schools that have direct access to a County Road?
2. Are there other schools with large commercial developments across the street?
3. Are there other neighborhoods with large commercial developments that take
access to a local street?
In response to this inquiry, I have identified several locations that appear to meet these
criteria. Aerial photos of these locations are attached for visual aid.
1. Schools on Co. Rd.
• Northview Elementary (Diffley Rd & Daniel Dr.)
• Faithful Shepherd Elementary (Yankee Doodle Rd.. & Westcott Woodlands)
• Pilot Knob Elementary (Lone Oak & Woodlark Lane)
• Cedar Elementary (Diffley Rd. & Nicols Rd)
2. Schools with large Comm. Dev.
• Same as #1 above
3. Residential and Comm Dev. With access onto local streets
• Town Center & Crestridge Dr./Denmark Ave.
• Cliff Lake Center & Rahn Rd (Cliff Lake Townhomes)
• Diffley Plaza & Blackhawk Rd
• Sodderholm Add & Lexington Way
• Bicentennial Add (Yankee Square) & Federal Dr.
• Nicols Rd and Slater Rd south of Cliff Rd.
• Country Home Heights and Avalon Ave. (Eagandale Center Ind Park)
• Thomas Lake Center & Thomas Lake Rd
The Mr. Trautz submitted an email stating:
"Of the options being discussed, two will work for us:
1. Full access at the "Walgreen's Access" point with a traffic light; close
the development's access to Daniel.
2. Access as described by the County Plat Commission - 3/4 access at the
Walgreen's Access point; Diffley/Daniel stays as it is; the Daniel access to
the development stays open.
The proposal to make the Walgreen's Access a 3/4 access point and to
close the developments access to Daniel does not work. The ability for
vehicles to enter and exit the site becomes too restrictive and prevents the
site from being operated as a retail development."
This information will also be made available at the meeting as well.
Respectfully,
Thomas A. Colbert
Director of Public Works
