ORDINANCE NO. BL2005-628
An ordinance to amend various sections of Title 17 of the Metropolitan Code of Laws, the Zoning Ordinance of the Metropolitan Government of Nashville and Davidson County, relative to undergrounding utilities in any residential subdivision where a new public or private street is to be constructed, all of which is more particularly described herein (Proposal No. 2004Z-005T).
WHEREAS, overhead utilities exist in many portions of Metropolitan Government of Nashville and Davidson County ("Metro");
WHEREAS, overhead utilities can have an undesirable aesthetic impact upon the character and quality of the neighborhoods in Metro;
WHEREAS, as a prominent part of the streetscape, overhead utility lines may detract from the visual quality of the neighborhoods;
WHEREAS, a one-time investment by a developer or property owner to underground utilities produces aesthetic returns to the Nashville community for generations;
WHEREAS, undergrounding utilities may encourage a more active and healthy life for Davidson County residents by creating more attractive streetscapes for pedestrians;
WHEREAS, use of underground utilities allows a greater variety of street trees to be planted and to grow to their natural canopy thereby reducing maintenance costs attributable to tree trimming and improving the aesthetic quality of streetscapes and neighborhoods;
WHEREAS, undergrounding utilities may contribute to increased property values in affected areas; and,
WHEREAS, the Metro Council finds for all of the foregoing reasons, and to promote the welfare of residents with respect to the aesthetic quality of subdivisions, the electric and communication distribution facilities should be located underground, where feasible, without affecting the quality of utility services.

The Board shall not act upon such a request without first receiving a recommendation from the Metro Planning Commission, as provided in Section 17.40.340.

Utilities connecting one alley to another alley may cross a public or private street above ground.
H. Property Owner Responsibility. The property owner and/or developer installing, requesting, or requiring the construction of the improvement, and not the Metropolitan Government or the utility, shall be responsible for the cost of placing utility lines underground and shall make the necessary arrangements with the serving utility companies. The utility shall have no obligation to underground facilities unless and until it receives full payment for costs to do so.
I. Non-Conforming Utility Equipment. Any utility equipment approved or installed, and operating prior to the effective date of this ordinance, may be maintained in its present condition and may be upgraded to conform to new technologies and regulatory requirements.
J. Existing City Franchises Not Affected. The provisions of this section do not and shall not be interpreted to waive any right enjoyed by Metro with respect to any franchisee, nor to waive the obligations created by any franchise. In the event that any provision of this section conflicts with any provision of a franchising agreement or ordinance, said franchise provision shall control.
