Infrastructure Development Standards

PART 2: UTILITY DESIGN CRITERIA AND CONSTRUCTION STANDARDS

I . UTILITY EXTENSIONS

A. GENERAL

The following provides a means by which the City of Bartow's utility systems may be connected to or extended. In general, developers are responsible for all cost and installation of utility systems within and adjacent to the proposed development, except for portions of individually metered service installations. Developments connecting to the City’s utility systems that are not within the incorporated limits of the City of Bartow shall be designed in accordance with the provisions of the City’s Infrastructure Development Standards.

B. PROCEDURES FOR REQUESTING UTILITY SERVICE

The extension of City of Bartow utility services to properties lying outside and either contiguous or non-contiguous to the corporate limits of the City of Bartow shall be considered by the City Manager. The following procedure shall be utilized in all applications for utility service:

1. In order to initiate the request, the petitioner should contact the Public Works Director and provide the following information in order for the City Administration to properly evaluate the request:

a. A project location map and complete legal description of the subject property.

b. Proof of ownership (e.g. a copy of deed to property site).

c. A comprehensive, itemized breakdown of the proposed land use intended for the subject site.

d. An estimate of the daily water and wastewater demands of the subject property. Unit consumption/generation rates shall be in accordance with City standards unless the developer can provide evidence that other consumption/generation rates would be more appropriate.

2. The Public Works Director will require at least ten (10) working days to consider the request for utility service for noncontiguous properties.

3. The petitioner must execute a "Petition for Utility Service" before the City Manager, will consider the request. The execution of a "Petition for Utility Service" obligates the developer to construct the utility system in compliance with certain conditions:

a. All utilities construction within the subject property shall be in conformance with all applicable City codes, specifications, and requirements.

b. All costs associated with the extension of City of Bartow utility services to the subject property are to be made at no expense to the City of Bartow, except as provided below for over-sizing.

Attachment "A" - Design Standards

4. Prior to the City’s approval of any application to provide water and/or sewer utility services to a location outside the city limits, the owner(s) of property to be served shall:

a. Properly execute at the time of application for utility service, a nonrevocable, recordable petition to annex into the city at such time as the property becomes eligible for annexation pursuant to Florida Statutes.

b. If the property is contiguous to current City limits, pay to the city at the time of such application the prevailing fees charged by the city relating to annexation which shall include, without limitation, fees to amend the future land use and zoning maps. The city clerk shall have the petition to annex duly recorded in the public records of Polk County, Florida, whereupon the petition shall constitute public notice of the matters reflected therein and bind all future owners to terms of the petition.

C. RESPONSIBILITY FOR INSTALLATION:

1. The developer shall be totally responsible for all installation costs within and/or adjacent to his property and all costs incurred except for that cost previously agreed upon by the City as the City's oversizing cost (See Section D) and except as noted below.

2. The City may elect to install any extension of the utility system required from existing facilities to the development on a joint participation agreement, requiring the developer to reimburse the City for the cost incurred by the City or may require the developer to provide the entire installation at his expense. Any portion of the facilities to be installed or materials supplied by the City must be labeled as such on the plans.

3. Where an extension will benefit other property owners and/or developments, the

City may consider the following options for line extensions:

a. The developer may prepay the entire cost of the extension. The developer will be reimbursed using line extension fees collected from other users connecting to the line within a ten-year period. Such reimbursement shall be up to 100% of the certified cost of the extension less the developer’s proportionate share of the cost of the extension. A Development Agreement shall be executed between the City of Bartow and the development to address the procedure for which the reimbursement shall occur. The City Manager shall have the authority to execute the Development Agreement on behalf of the City of Bartow provided that the terms and conditions of the agreement do not deviate from other City codes or regulations that may apply.

b. The City may pay the cost of the extension if a letter of credit or other acceptable collateral is provided by the developer guaranteeing the City reimbursement of the entire cost of the extension over the subsequent ten-year period.

4. Ninety percent of all line extension fees (excluding the developer's proportionate share of the cost of the extension) will be credited to the developer's debt for a five ten-year period. Said ten-year period commences at the time of final acceptance of the extension by the City. These extension fees are in addition to usual impact fees and connection fees as provided for in the Code of Ordinances of the City of Bartow.

5. All line extensions will be of the City's minimum size or greater if needed by the developer.

6. Where it is deemed by the City to be more feasible to serve a development with a new water or wastewater facility rather than by extending existing City utilities, developer shall be responsible for the cost of constructing the required facilities.

Water and/or wastewater treatment plants may be designed by the Developer's Engineer in accordance with City standard details and specifications and requirements of the City. Where desired, the City may require over sizing of the facility and reimburse the developer in accordance with the following procedures.

D. OVERSIZING OF UTILITIES EXTENSIONS

1. The City may, at its discretion, require the oversizing of utility lines, lift stations, and/or other utility facilities to benefit the overall utility system.

2. Where the City elects to oversize any utility line, lift station, or other utility facility, the City shall reimburse the developer for the documented cost differential directly attributable to oversizing or additional facilities of benefit only to the City. The determination of that portion of the extension cost paid by the City shall be made from a minimum of three (3) bids, submitted for evaluation by the City.

II. SANITARY SEWERAGE

A. Where the City determines that public sanitary sewers are feasible, such sewers shall be installed by the City or its agents at the expense of the developer or by the developer to City specifications and design standards and under City supervision.

B. Where the City is unable to provide public sanitary sewers, private septic tanks will be permitted only if approved by the Department of Health. Where a private sewerage plant is proposed, it must be approved by the FDEP and the City. Any such private sewerage plant shall be designed as an extended aeration facility in accordance with FDEP and Ten State standards. Plants shall be sized according to the below sewerage flows:

c. The pump station pumps and motors must be of a make, size, and specification approved by the City Utilities Department.

d. The development must generate a minimum average wastewater flow of

5,000 gallons per day.

e. Where the sizing of the pump station pumps and motors is dependent upon the pump station serving future phases of development, either on or off-site, then the developer must sufficiently document this future flow and provide a reasonable time frame for this additional capacity to be required of the station.

f. The design and construction of the pump station and the wastewater force main shall be approved by the City Water/Wastewater Director and Public Works Director.

g. If required, the lift station shall be provided with either of the following:

(1) An emergency generator, permanently installed, of sufficient size to operate all pumps and equipment.
