In order to defray a part of the costs incurred by the city in inspecting the installation of the improvements required by this chapter, the subdivider shall, before he proceeds with any construction or installation, present a certified check or money order made payable to the city council in an amount equal to three percent (3%) of the engineer's estimate of the cost of the improvements.
