26.3 Required Improvements | Oro Valley Zoning Code

Section 26.3 Required Improvements

It is the purpose of this section to establish, in outline, the minimum acceptable standards for improvement of public streets and utilities, to define the responsibility of the subdivider in the planning, constructing and financing of public improvements and to establish procedures for, and approval of, engineering plans.

All improvements required in streets, alleys or easements that are required as a condition to plat approval are the responsibility of the subdivider provided, however, that he may be allowed to meet the requirements by participation in an improvement district approved by the Town.

1. It is the responsibility of the subdivider to have prepared by a registered civil engineer, registered in the State of Arizona, a complete set of engineering plans, satisfactory to the Town Engineer, for construction of required improvements. Such plans shall be based on the approved preliminary plat and be prepared in conjunction with the final plat.

2. Engineering plans shall be approved by the Town Engineer prior to Town Council approval of the final plat.

1. All relocation, filing, and reconstruction of facilities shall be constructed to standards of the owning utility and Town Engineer.

2. All improvements in the public right-of-way shall be constructed under the inspection and approval of the Town Engineer.

3. All underground utilities to be installed in streets shall be constructed prior to the surfacing of such street. Service stubs for underground utilities to platted lots within the subdivision shall be placed in such manner that will not require road cuts or tunneling beneath existing street improvements when service connections are made.

1. The purpose of the plan review is to insure that all plans conform to sound engineering concepts as well as conforming to the general development of the Town of Oro Valley.

2. Plan review shall not remove any engineering responsibility from the developing engineer.

All streets and alleys adjacent and within subdivisions shall be graded and surfaced to cross-sections, grades and standards according to the “Standard Specifications, Standard Details and Design Standards” of the Town of Oro Valley and approved by the Town Engineer. Dead end streets serving more than 4 lots shall be provided with a graded and surfaced temporary turning circle.

Signs shall be placed at all street intersections and be in place by the time the street pavement is ready for use. Specifications for design, construction, location and installation shall be in accordance with approved Town of Oro Valley standards. If the intersection contains a public street, fabrication and installation of the completed sign unit shall be by the Town. The total cost of installation shall be on record with the Town Engineer and this cost shall be borne by the subdivider. The subdivider may elect to have the Oro Valley Streets and Roads Department install street name signs at intersections containing only private streets at the current Town cost on file with the Town Engineer. The total cost of said installation shall be borne by the subdivider.

Proper and adequate provisions shall be made for disposal of storm waters. The requirements of this Section shall apply equally to grading of private property and public streets. Existing major watercourses shall be dedicated as drainageways or easements. The type, extent, location and capacity of the drainage channels shall meet the approval of the Town Engineer and shall be constructed in accordance with plans approved by the Town Engineer.

Sewage disposal facilities shall be installed to serve each lot and be subject to Pima County Health Department and/or Pima County Wastewater Management standards.

Each lot shall be supplied with safe, pure and potable water in sufficient volume and pressure for domestic use and fire protection in accordance with Town standards. Fire hydrants shall be installed in accordance with current Town standards at locations designated by the Fire Department and approved by the Town Engineer at the expense of the subdivider.

Permanent monuments shall be installed in accordance with current Town standards at all corners, angle points and point of curves and all street intersections. After all improvements have been installed, a registered land surveyor or civil engineer shall check the location of monuments and certify their accuracy.

Iron pipe or round reinforced steel bars not less than 1/2 inch in diameter shall be set at all corners, angle points and points of curve for each lot within the subdivision prior to the recording of the plat except that the Development Committee may approve delay where topographic or construction conditions make it necessary.

Street lights shall be installed, if required, as designated by the Town Engineer, in accordance with the Town standards. All lights shall be installed on metal standards with fixtures and standards and layout approved by the Town Engineer. All of the above improvements shall be installed at the expense of the subdivider.

1. All electric lines and all telephone lines necessary to serve the subdivision shall be installed underground unless, upon recommendation of the Town Engineer, the Town Council finds it is impractical to do so.

2. The subdivider shall be responsible for the requirements of this Section and shall make the necessary arrangements with each of the public utility companies involved for the installation of underground facilities. Letters from each of the public utility companies indicating that the arrangements have been made shall be submitted to the Planning and Zoning Administrator at the time the final subdivision plat is filed.
