(a)

No development shall be approved by the city without the developer having first provided, as hereafter set forth, all improvements, dedications, and maintenance guarantees required by this chapter. The city engineer shall be responsible for ensuring adequate inspection of construction of all improvements except sanitary sewer system and private utilities for compliance with the approved plans and specifications. He shall issue a certificate of completion upon the approved completion of the work subject to the maintenance period provided for.

(b)

The engineer of record shall certify in writing that the completed improvements are completed in accordance with the approved plans and specifications. No certificates of occupancy shall be issued within the development until all improvements for the development have been accepted by the city.

(Ord. No. 93-01, § 6.0, 11-16-1992)

(a)

Following acceptance by the city of the construction of improvements which are to be dedicated to the city, the developer shall be required to maintain the improvements in first class condition until the city commission accepts the improvements for city maintenance. Said developer's maintenance period shall be a minimum of one year. The city commission shall require cash in escrow or a first mortgage (or some other type of cash guarantee as recommended by the city attorney) guaranteeing all improvements against defects in design, material and workmanship, and further guaranteeing that the developer shall maintain all said improvements in first class condition for the required period of time. This guarantee shall be in the amount of ten percent of the construction cost of the improvements.

(b)

Should the developer fail to maintain any of the improvements in first class condition during the developer's maintenance period as herein specified, the city engineer shall notify the developer, in writing, giving the developer 15 days to take corrective actions. Should the developer fail to take the appropriate corrective action, the city may correct the problem, deducting the cost from the developer's guarantee.

(c)

The developer may request the city commission to accept the improvements for maintenance at the time of or after the acceptance of the construction improvements, but prior to the expiration of the developer's one-year maintenance period. When this occurs, it shall be the responsibility of the developer to sod all areas of the constructed improvements, where the potential for erosion exists because of an inadequate stand of grass. Such areas which may require sodding shall include, but not be limited to, shoulders, swales, and drainage retention areas. When such sodding is completed in a manner acceptable to the city engineer, the city commission may accept the improvements for maintenance by the city, provided that all improvements are in first class condition. However, the cash guarantee will be retained for the full one-year maintenance period to guarantee all improvements against defects in design, materials, and workmanship.

(d)

The city commission shall not accept the improvements for maintenance by the city nor release the cash guarantee until it has been determined that all improvements are in first class and acceptable condition.

(Ord. No. 93-01, § 6.1, 11-16-1992)

At least one corner of the subdivision shall be designated by course and distance (tie) from a readily discernible reference marker such as a U.S. government marker, section corner, or quarter-section corner. When such a monument or station is not available, the tie shall be made to some permanent and readily recognizable landmark or identifiable point, physical object or structure.

(2)

Monuments. At least two monuments, shall be installed as control corners within each block within the subdivision. The surveyor shall install additional monuments if required by the city engineer. All monuments shall be constructed of concrete and shall be at least four inches in diameter or square and not less than two feet in length. Each monument shall have embedded in its top or attached by a suitable means a noncorrosive metal place marked plainly with the point, the surveyor's registration number, and the month and year it was installed, and the words "Permanent Reference Monument" or the initials "PRM." Monuments shall be set securely in the ground so that the top is flush with the finished grade.

(3)

(4)

Location of driveways. There shall be a minimum distance of ten feet between any two openings on the same street for any one use. No point of access shall be allowed within ten feet of the intersection of the right-of-way lines of two public streets. Where right-of-way lines intersect in the form of an arc, the required ten feet shall be established as near as practical to the center of the arc. The location and width of driveways required by these regulations shall be established by measurements taken along the right-of-way line. Driveway entrance shall have no less than a 30-degree flare between the right-of-way line and the curb, or if no curb, the traveled street, to provide for the turning arc of vehicles entering and leaving the abutting property.

All streets shall be public unless private streets are permitted in accordance with section 24-571 or as may otherwise be approved by the city commission upon recommendation of the city planner, city engineer and city attorney. The city commission shall not approve a private street in a proposed development if it can be reasonably assumed that such street will be needed to serve the area adjoining the proposed development. All public streets shall be dedicated to the perimeter of the proposed subdivision unless they are permanently terminated by a cul-de-sac or an intersection with another street.

(Ord. No. 93-01, § 6.3.6, 11-16-1992)

A proposed street which is obviously in alignment with another existing and named street, shall bear the assigned name of such existing street. In no case, except as provided for in the preceding sentence, shall the name of a proposed street duplicate or be phonetically similar to the assigned name of an existing street in the county, irrespective of the use of a suffix (e.g., street, avenue, boulevard, drive, place, court, etc.). Such suffix shall be determined according to the guidelines set forth in the Street Naming Chart (Appendix A) which is on file in the office of the city clerk. Street names shall require approval by the city commission.

(Ord. No. 93-01, § 6.3.7, 11-16-1992)
