To provide adequate services and facilities appropriate to the scale and type of development.

(Ord. 619, 2003)

A. The design of all improvements within existing and proposed rights-of-way and easements, all improvements to be maintained by the city, and all improvements for which city approval is required, shall comply with the requirements of the most current adopted Standard Specifications for Public Works Construction in the City of Carlton.

B. The location, design, installation and maintenance of all utility lines and facilities shall be carried out with minimum feasible disturbance of soil and site.

C. Standards for Water Improvements.

1. All developments shall be required to be linked to existing water facilities adequately sized to serve their intended area by the construction of water distribution lines, reservoirs and pumping station which connect to such water service facilities. All necessary easements required for the construction of these facilities shall be obtained by the developer and granted to the city pursuant to the requirements of the city.

2. Specific location, size and capacity of such facilities will be subject to the approval of the city engineer with reference to the most current adopted city of Carlton water master plan. All water facilities shall conform with existing city pressure zones and shall be looped where necessary to provide adequate pressure and fire flows during peak demand at every point within the system in the development to which the water facilities will be connected. The city will not expect the developer to pay for the extra pipe material cost for waterlines exceeding eight inches in size. Installation costs shall remain entirely the developer’s responsibility.

3. The design of the water facilities shall take into account provisions for the future extension beyond the development to serve adjacent properties that, in the judgment of the city, cannot be feasibly served otherwise.

4. Design, construction and material standards shall be as specified by the city engineer for the construction of such public water facilities in the city.

D. Standards for Sanitary Sewer Improvements.

1. All developments shall be required to be linked to existing sanitary sewer collection facilities adequately sized to serve their intended area by the construction of sewer lines which connect to existing adequately sized sewer facilities. All necessary easements required for the construction of these facilities shall be obtained by the developer and granted to the city pursuant to the requirements of the city.

2. Specific location, size and capacity of such facilities will be subject to the approval of the city engineer with reference to the most current adopted wastewater facilities plan. All sewer facilities shall be sized to provide adequate capacity during peak flows from the entire area potentially served by such facilities. The city will not expect the developer to pay for the extra pipe material cost for sanitary sewer lines exceeding twelve (12) inches in size. Installation costs shall remain entirely the developer’s responsibility.

3. All properties shall be provided with gravity sanitary sewer service to a public sanitary sewer system except for parcels which have unique topographic or other natural features which make gravity sewer extension impractical as determined by the city engineer. Pumping stations will be allowed only when it has been demonstrated to the satisfaction of the city engineer that the development cannot be served by gravity. Maintenance of residential pumping stations are the responsibility of the property owner.

4. Temporary sewer service facilities, including pumping stations, will be permitted only if the city engineer approves the temporary facilities, including all facilities necessary for transition to permanent facilities.

5. The design of the sewer facilities shall take into account provisions for the future extension beyond the development to serve upstream properties that, in the judgment of the city, cannot be feasibly served otherwise.

6. All land divisions or other developments requiring subsurface sanitary sewer disposal systems shall be prohibited.

7. Design, construction and material standards shall be as specified by the city engineer for the construction of such sewer facilities in the city.

8. Prior to acceptance of the sanitary sewer system by the city, the sewers shall be flushed and inspected by the city as required by the Standard Specifications for Public Works Construction in the City of Carlton. All costs shall be borne by the developer.

E. Street Lights. All developments shall include underground electric service, light standards, wiring and lamps for street lights according to the specifications and standards of the city engineer. The developer shall install all such facilities and make the necessary arrangements with the serving electric utility for the street lighting system.

F. Private Utilities. All development which has a need for private utilities, including but not limited to electricity, gas, and communications services shall install them pursuant to the requirements of the district or company serving the development.

1. Except as otherwise provided herein, all utility lines, cables or wires, including but not limited to those used for electricity, communications services and street lighting which are on or adjacent to land partitioned, subdivided or developed within the city of Carlton after the effective date of the ordinance codified in this title, shall be required to be placed underground. The intent of the city is that no poles, towers, or other structures associated with utility facilities shall be permitted on any street or lot within or adjacent to such partition, subdivision or development.

2. Exceptions. Above ground facilities shall be permitted for the following in which case the above provisions shall not apply:

a. Emergency installations or electric transmission lines or to through feeders operating at distribution voltages which act as a main source of supply to primary lateral and to direct connected distribution transformers and primary loads. Should it be necessary to increase the capacity of major power transmission facilities for service to the area, such new or revised installations shall be made only on rights-of-way or easements on which existing overhead facilities exist at the time of such capacity increase;

b. Appurtenances and associated equipment such as surface-mounted transformers, pedestal-mounted terminal boxes, meter cabinets, telephone cable closures, connection boxes and the like;

c. Structures without overhead wires, used exclusively for fire alarm boxes, streetlights, or municipal equipment installed under the supervision and with the approval of the city engineer;

d. Power substations, pumping plants, and similar facilities necessary for transmission or distribution of utility services shall be permitted subject to compliance with all zoning regulations and other applicable land use regulations. The engineer for all such facilities, prior to any construction being started, shall approve plans showing landscaping and screening;

e. Certain industries requiring exceptionally large power supplies may request direct overhead power as a condition;

f. If existing overhead utilities within or adjacent to the development total less than one hundred fifty (150) linear feet, the city may allow the applicant to record an approved improvement deferral agreement, see Section 17.216.030, in lieu of relocating existing private utilities underground at the time of development.

3. Information on Development Plans. The developer or subdivider shall show on the development plan or in his or her explanatory information, easements for all underground utility facilities. Plans showing the location of all underground facilities as described herein shall be submitted to the city engineer for review and approval. Care shall be taken in all cases to ensure that aboveground equipment does not obstruct vision clearance areas for vehicular traffic.

4. Future Installations. The owner(s) or contract purchaser(s) of subdivided real property within a subdivision shall, upon conveyance or transfer of any interest including a leasehold interest in or to any lot or parcel of land, provide in the instrument conveying such interest a covenant running with and appurtenant to the land transferred under which grantee(s) or lessee(s), their heirs, successors, or assigns mutually covenant not to erect or allow to be erected upon the property conveyed any overhead utility facilities, including electric, communication, and cable television lines, poles, guys, or related facilities, except such facilities as are exempt from underground installation under this title or are owned or operated by the city. Such covenant shall require grantees to install, maintain, and use underground electric, telephone, cable television, or other utility services used or to be used to serve the premises. A copy of the covenant shall be submitted with the final plats.

K. Easements for public and private utilities shall be provided as deemed necessary by the city, special districts, and utility companies. Easements for special purpose uses shall be of a width deemed appropriate by the responsible agency. Such easements shall be recorded on easement forms approved by the city attorney and designated on the final plat of all subdivisions and partitions. Minimum required easement width and locations are as follows:

(1) Centered on utility line

(2) Centered on property line, where possible

(3) All property lines fronting existing or proposed street rights-of-way

(4) Measured from edge of right-of-way

(5) Determined on a case-by-case basis
