At cross street intersections, two signposts shall be located diagonally across the intersection from each other. Only one street signpost shall be required at T-street intersections.

The administrative procedures for installing the subdivision improvements required herein shall be as follows:

158.1. When construction may begin. Construction and installation of any required public improvements as described herein shall not begin until the planning commission has given preliminary approval of the new subdivision. The subdivider shall then confer with the roads superintendent to determine the method and estimated cost of the construction and installation of the required improvements.

158.2. Inspections and approval. During the construction and installation of the required public improvements, the roads superintendent shall from time to time make field inspections and supervise said work as predetermined and agreed upon by the roads superintendent and the subdivider. After completion of all the construction and installation of the required public improvements and if the said work has met the specifications as described herein, as determined by the roads superintendent, the zoning enforcement official shall notify the subdivider in writing of the approval of said work.

158.3. Official acceptance by the board of commissioners. The board of commissioners shall officially accept the completed work on the construction and installation of required public improvements not less than one year from the date of the written acceptance by the zoning enforcement official, but not before approval by the planning commission of the final plat.

158.4. Performance bond. If the subdivider does not wish to construct and install any or all of the required public improvements as described herein prior to submitting the subdivision plat to the planning commission for final approval, a performance bond shall be required, such bond being equal to the estimated cost of construction. When the work has been completed satisfactorily, the board of commissioners shall release 90 percent of the funds with a letter of approval to the subdivider. The remaining ten percent shall be placed in escrow for maintenance purposes.

158.5. Maintenance of completed work. The subdivider shall maintain his completed work until the official acceptance by the board of commissioners as described above. The subdivider shall be required to sign a maintenance agreement with the board of commissioners. If a maintenance bond is posted by the subdivider, a bond equaling ten percent of the construction cost shall be required. During the maintenance period, the roads superintendent shall make final inspection and notify the subdivider and the bonding company of the cost of making necessary corrections and the cost of maintenance. These costs shall be deducted from the maintenance funds, and the subdivider charged with any costs above the amount of maintenance funds. If the work is acceptable at this time, the remainder of the maintenance funds shall he released to the subdivider.

158.6. Subdivider's responsibility. The subdivider shall incur the cost of construction and installation of all required public improvements based on the following:

a.

Streets. Incur the cost for the construction of streets up to 27 feet in surface width from back of curb to back of curb, or 22 feet in surface width from edge of surface to edge of surface if no curbs and gutters are installed.

b.

Water and sewer systems. Incur the cost for the installation of all water and sewer systems which are required to serve the new subdivision and tie in with existing water and sewer systems based on the specifications set forth herein.

c.

Sidewalks. Entire cost if provided.

Streets. Incur cost for any additional required pavement which is in excess of 27 feet for streets with curbs and gutters and in excess of 22 feet for streets without curbs and gutters, and any additional grading and paving related thereto.

b.

Water and sewer systems. Incur not more than one-half the cost for any difference in the cost of the laying of oversized pipe and outfall systems which are needed in excess of the required water and sewer facilities needed to exclusively serve the new subdivision as determined by the planning commission.

158.8. Property owner's responsibility. Whenever the county commission is petitioned by the property owners to upgrade a street to higher construction standards, the property owners shall then incur the entire cost for said improvements, based on the footage along the property line of each lot abutting the street which is being improved.

158.9. Estimated costs for construction and installation. The current unit prices in effect at the time of submission of plans plus ten percent shall be used in determining the total estimated cost for construction and installation of required public improvements in new subdivisions.
