rhe City Initially did not believe that Native Seeding for Erosion Control would be needed due to the use of other erosion control methods. It is
now apparent that Native Seeding Is necessary after construction to provide permanent erosion control. During construction an 18" RCP was
ilscovered outfailing Into the channel from an adjacent pond. The channel bank is being regraded In the area of the outfall so It Is necessary to
ihorten the pipe and build a new headwall.

The Kensington Detention Improvements project is located just south of Dell Way, adjacent to
Dell's Building 1 at 401 Dell Way. The project consists of two inline detention ponds. Two
concrete walls are being constructed to form the two ponds. An existing berm is being
renovated to accommodate one of the walls and increase pond capacity.
Quantity Adjustment/Change Order No. 1 includes the cost of constructing a concrete headwall
and safety end treatment for the pipe. It also includes the cost of applying native seed for
erosion control. The headwall needs to be added to the project after we discovered a previously
unknown 18" RCP that will need to be moved. The native seeding is necessary because after
thinning out the trees in the project area we determined that permanent vegetation is needed to
fully stabilize the project site.
Change Order No. 1 is for $29,100.00. This includes the cost of labor, additional materials and
equipment for the work. The total contract amount will be adjusted to $967,645.25.
Staff recommends approval.
Cost: $29,100
Source of Funds: 2014 Drainage Revenue Bonds
