Engineer prior to the approval of the site development plans.

Prior to construction of the building, the public alley must be vacated. Unless the applicant intends to vacate the alley by replat, the applicant is responsible for submitting a written request to the Development Review Manager asking that a vacation petition be prepared for the entire alley within Block 6, Original Town of Shawnee.  Once prepared, the applicant is responsible for circulating the petition to the signed by all property owners within the block. The vacation petition must be heard and approved by the City Council prior to the approval of the site development plans submitted for construction permit

Engineering staff is concerned that the proposed placement of the two trash enclosures may create blind spots for motorists exiting the site.  The applicant is responsible for verifying that these locations comply with AASHTO sight distance design criteria for driveways.  It may be necessary to move the enclosures farther east along the outer walls of the buildings.

The driveway at the rear of the building is only 17 feet wide, which only complies with City standards for a one-way drive.  The applicant is responsible for determine the direction of traffic flow and sign the entrance and exit ends of the drive accordingly.

Typically, an approach must have a minimum separation of 125 feet from a street intersection, measured from back-of-curb to back-of-curb.  While the limited width of the development site precludes it complying with this City standard, City staff does not believe the intended land uses will create any traffic problems at this specific location.


Barton Street and 57th Street shall comply with the following modified geometric design standards for a local residential street:

The width of the existing rights-of-way will remain unchanged.

The roadway will be designed for a minimum safe speed of 25 mph.

The centerline grades will be a minimum of 1 percent and a maximum of 12 percent.  The maximum centerline grade for a cul-de-sac will be 10 percent.  The maximum centerline grade at all intersections will be 4 percent.

Vertical curves will be designed for a minimum stopping sight distance of 155 feet (K=12, crest; K=26, sag).  [Note changes per AASHTO.]

Horizontal curves will be designed with a minimum radius of 175 feet.

A tangent segment having a minimum centerline length of 50 feet will be provided between reverse curves.  A tangent segment will be provided at all street intersections from the beginning of the curb returns to the centerline of the intersecting street.
