§ 835. Utilities.

(a)

Underground wiring required. All electric, lighting, telephone, and cable television distribution lines shall be installed underground, except those feeder lines necessary to serve the subdivision and in locations approved by the Director. Switching enclosures, pad mounted transformers, and service pedestals may also be installed above ground in locations approved by the Director. The City Council may approve, upon recommendations from the Commission, above ground installations in whole or in part for subdivisions, only when a request is submitted by the subdivider with documentation that supports the impracticability of installing such utility lines underground.

(b)

Water facilities. The subdivider shall secure water and service to each lot within the subdivision for the purpose of providing sufficient potable water supply and fire protection. The subdivider shall arrange for installation of water mains. Fire hydrants shall be located and installed in accordance with the specifications established by the fire district serving the subdivision.

(c)

Sanitary and storm sewers.

(1)

Adequate sanitary sewer collection lines shall be provided and accessible to each lot. All sanitary sewers, sanitary sewer connections, manholes, and other sanitary installations serving the subdivision shall comply with MSD design standards and design standards established by the Director. In instances where there are differences between MSD standards and those established by the Director, the most restrictive standard shall apply. The subdivider shall be responsible for installing all required building service connections.

(2)

Every subdivision shall be designed to control stormwater runoff. All storm sewers, storm sewer connections, detention/retention facilities, and other storm drainage improvements shall comply with MSD design standards and design standards established by the Director. In instances where there are differences between MSD standards and those established by the Director, the most restrictive standard shall apply.

(3)

In residential subdivisions, drainage/retention facilities and land area required to provide access to such facilities shall be located within common ground. Drainage detention facilities or other storm drainage facilities that will not be maintained by MSD shall be conveyed to the trustees of the subdivision association for maintenance purposes, in accordance with this subdivision code.

(4)

In single lot subdivisions, drainage detention facilities or other storm drainage facilities that will not be maintained by MSD shall be maintained by the property owner.

(5)

Drainage discharge. All drainage provisions shall be of such design to carry surface waters to the nearest practical storm drain or natural watercourse as approved by the Director. The finished grade of sites, one (1) acre or greater in area, from which all or a portion will drain into a natural or improved drainage way, shall be so designed so that stormwater runoff is intercepted by diversion swales or area inlets, and lowered to a stable outlet constructed of concrete, rip-rap, pipe, or other techniques required by MSD or as specified by the Director. The rate of discharge of surface water runoff shall be in accordance with the requirements of MSD, except that the Director may require more restrictive discharge rate in areas where flash flooding, bank erosion, or other chronic stormwater drainage problems exist.

(d)

Other utilities. The design and installation of other utilities (e.g., electrical distribution, gas mains and services, telephone, and cable television) shall be provided at a service level necessary for the subdivision and in accordance with the specifications, approval, and inspection requirements of the applicable utility company.

(e)

All underground utilities. All existing trees that are to be preserved shall be protected from damage by excavation activities. Roots of such trees shall not be cut without express approval of the Director.
