The Salina City Commission will consider adding more than $115,000 to the engineering agreement for the East Crawford Street and Brookwood Trail project, potentially bringing total design expenses to $492,710.90.

Commissioners are scheduled to consider Amendment No. 1 to the city’s agreement with Lochner during their July 13 meeting. The amendment would add drainage, detention-basin, pedestrian-crossing and traffic-signal design work to the existing contract.

The nearly $493,000 figure represents engineering and design services. It does not include the eventual cost of road, drainage, signal or trail construction.

Original Design Agreement Totaled $377,184

The City Commission approved the original Lochner agreement in August 2025. It included:

$297,244.78 for design work along East Crawford Street
$79,939.22 for hydraulic analysis and pedestrian-bridge footing design near Brookwood Trail

Together, the original engineering authorization totaled $377,184. The city identified general obligation bonds supported by property taxes as the funding source.

The East Crawford design covers the area from Markley Road east to Holmes Road. However, the initial construction package is expected to cover only the section from Markley Road to Prairie Lane.

Plans call for a three-lane roadway with one travel lane in each direction, a center turn lane, a sidewalk on the north side and a 10-foot-wide bicycle and pedestrian path on the south side. The existing narrow drainage culvert beneath Crawford would also be widened.

City staff previously said the project became more immediate because of the construction of Fire Station No. 4 at Markley Road and East Crawford. The current roadway east of the station narrows from four lanes to two and lacks curb, gutter and sidewalks.

Amendment Would Add $115,526.90

The proposed amendment contains two additional engineering costs:

$86,531.28 for detention-basin, drainage and Brookwood Trail crossing work
$28,995.62 for updated traffic analysis and signal design

Combined, the proposed additions total $115,526.90, which would increase the engineering agreement by approximately 31%.

The detention-basin portion would include hydrologic and hydraulic modeling, evaluation of an existing pond, development of a proposed basin, drainage reports, grading plans, erosion control, landscaping and utility coordination.

Engineers would also evaluate whether reducing drainage flows could lower the cost or size of downstream structures. That work includes reviewing alternatives for the Brookwood Trail crossing and designing a possible non-bridge pedestrian crossing.

The city had previously purchased a small pedestrian bridge for the Brookwood Trail location. The original design agreement included the drainage study, no-rise certification and structural footing design needed to place the bridge. The amendment would now compare that approach with alternative crossing designs.

The $86,531.28 detention-basin component includes 461 estimated labor hours, along with overhead and a fixed fee.

Traffic-Signal Work Also Expands

The additional $28,995.62 would pay for updated traffic volume and signal-warrant analysis, along with signal layouts for the intersections of East Crawford and Markley Road and East Crawford and Prairie Hawk Drive.

The amendment includes final design updates for the Markley Road intersection. Final Prairie Hawk signal plans were already included in the original contract and would not carry an additional design charge under this amendment.

The additional traffic work is estimated to cost $28,995.62, including labor, overhead and a fixed fee.
