C. - Bond amount estimate.

1.

The subdivider's engineer shall submit an itemized, component cost estimate of improvements planned for the subdivision, including:

a.

Subdivision improvements, including but not limited to streets, water improvements, sewer improvements, storm drainage improvements, street lighting and sidewalks;

b.

Erosion and sediment control measures (refer to Erosion and Sediment Control Ordinance and section 6.C.3.);

c.

Stormwater management facilities and best management practices infrastructure;

d.

Landscaping improvements;

e.

Other public or private infrastructure, as determined by the city engineer, to be dedicated to and maintained by a public agency;

f.

Proffered improvements and financial commitments related to conditional zoning approvals for the subdivision; and

g.

Other items as may be required for subdivision bonding by the zoning administrator.

2.

In lieu of a subdivider's engineer's bond estimate, the zoning administrator may accept a bond estimate based on an executed contract for the construction of required improvements. Acceptance of the bond estimate shall be at the sole discretion of the zoning administrator upon review and recommendation by the city attorney. The contractor shall be required to post a performance bond with like surety, in like amount and so conditioned as to comply with all other requirements in this section.

3.

The bond amount estimate shall be submitted to and reviewed by the city engineer (1) prior to the final review of the surety (bond) agreements by the city attorney and formal acceptance by the city council (or its agent), and (2) prior to approval of the public improvements plan. The component cost estimate for bonding shall be based upon industry norms within the region and/or city standard unit prices. The bond amount estimate shall include a reasonable allowance for administrative costs, inspection and fees, inflation over the expected duration of construction, potential damage to existing streets or utilities during the construction and occupancy period, provided that this allowance shall be equal to not less than twenty (20) percent of the total estimated construction costs.

4.

The erosion and sediment control bond shall be issued as a separate bond instrument from the subdivision improvements bond.
