(Code 1975, § 23-66.3)

§ 78-290 Charges and deposits for connections to existing mains and laterals.

Water service.

All applicants for water service will be required to make a meter deposit (payment security deposit) for each water service connection, such deposit to remain with the city throughout the term of the service contract. The amount of the deposit shall be determined in section 78-171 and this section.

A building contractor shall place a meter deposit as established in Appendix A for each standard service requested, or may place a floating meter deposit as established in Appendix A, which shall be applicable to all services in his name at a given time. The contractor shall be liable for all charges for water used until occupant makes deposit. A service charge as established in Appendix A shall apply to each meter.

An applicant for service from a fire hydrant where water is placed in a tank truck or other container shall place a meter deposit with the city, the amount of which will be specified by Appendix A. Fire hydrant meters are designed for use in construction projects, the exact location of which will be required on the application. Each applicant shall be required to submit their meter each month for reading purposes. Procedures for use of fire hydrant meters shall be established by the Utility Services Manager. Should an applicant fail to provide a reading, he shall be billed a minimum as established in Appendix A, per month. The deposit will be refunded, or in the event a balance is due, applied against the final bill for services required upon termination of the contract. The city will not pay interest on meter deposit funds.

In locations where a complete service connection, including tap, service line, curb stop, meter, and box, were paid for or installed by a developer or other prior single customer, no charges are made other than the meter deposit (above) and the regular monthly service charges as set forth in article III of this chapter.

At locations where only a partial connection has been previously paid for or installed, including only the tap, service line or curb stop and setter, the applicant for service shall pay (in addition to the meter deposit) the cost of completing the service connection with meter and box, which costs are nonrefundable.

For all services three-quarter inch through six inches an estimate of the cost plus the amount set out in Appendix A for the connection will be provided by the city and a deposit of the estimated amount will be required before work is started on the installation of such connection. Should the final cost of the work exceed the amount of deposit, a statement showing the amount of the excess will be immediately furnished to the person having made the deposit, and this amount will be due before water service is actually begun. Should the final cost be less than the amount of the estimate or deposit, a refund of overpayment will be immediately made to the person from whom the deposit was received.

At locations where no part of the service connection is existing, or previously paid for, but a distribution main is existing adjacent to the property to be served, the nonrefundable connection charge plus a fee as established in Appendix A shall be quoted by the city at the time of installation.

This is in addition to the meter deposit. Should the service line required be longer than 50 feet, or should the customer desire larger service, an estimate of the cost for the connection will be provided by the city, and a deposit of the estimated amount will be required before work is started on the installation of such connection. Should the final cost of the work exceed the amount of the deposit, a statement showing the amount of the excess will be immediately furnished to the person having made the deposit, and this amount will be due before water service is actually begun. Should the final cost be less than the amount of the estimate or deposit, a refund of overpayment will be immediately made to the person from whom the deposit was received.

Where applicable there shall be added the cost of street repairs as follows: A minimum street cut of an amount as provided in Appendix A shall be deposited at the time water service is requested and before service is started on installation of such connection. Should the final cost of the work exceed the amount of the deposit, a statement showing the amount of the excess will be immediately furnished to the person having made the deposit, and this amount will be due before water service is actually begun. Should the final cost be less than the amount of the deposit or estimate, a refund of overpayment will be immediately made to the person from whom the deposit was received.

Where a single customer desires to increase the size of his existing service connection, the city shall determine the charges for the larger service connection, and shall apply a credit against the charges of the larger connection equal to 75 percent of the cost of the existing meter.

Extension of the service piping from the city's meter and curb stop shall be accomplished by the customer at his expense; however, such installation shall be in accordance with the applicable ordinance of the city.

Sewer service.

Applicants for sewer service who also have posted the meter deposit as established in Appendix A for water service to the same location are not required to post a separate deposit for sewer service; however, if the applicant receives sewer service only, or for any other reason has not posted the water meter deposit, then he will be required to make a sewer service payment security deposit, in the amount as established in Appendix A, for each such sewer service connection, which will remain on deposit with the city throughout the term of the service contract. The deposit will be refunded, or in the event a balance is due, applied against the final bill for services rendered, upon termination of the contract. The city will not pay interest on such deposit funds.

Where the furnishing of sewer service by the city does not require the extension of lateral sewers or other sewer mains as defined under "point of service" to serve a new single customer, the charge for the right to connect to the system shall be as established in Appendix A, except in a developed subdivision where a developer has paid for the installation of sewer facilities, then the charge shall be as provided in Appendix A.

Where applicable there will be added the cost of street repairs as follows: A minimum street cut deposit as established in Appendix A shall be deposited at the time water service is requested and before service is started on installation of such connection. Should the final cost of the work exceed the amount of the deposit, a statement showing the amount of the excess will be immediately furnished to the person having made the deposit, and this amount will be due before water service is actually begun. Should the final cost be less than the amount of the deposit or estimate, a refund of overpayment will be immediately made to the person from whom the deposit was received.

No permits for septic tanks will be issued until the person so desiring shall first have a percolation test run and deliver such tests, along with the construction plans for the septic system, to the county health department. Only after review and approval in writing will a building permit be issued.

Where applicable there shall be added the cost of street repairs as follows: A minimum street cut as established in Appendix A shall be deposited at the time water service is requested and before service is started on installation of such connection. Should the final cost of the work exceed the amount of the deposit, a statement showing the amount of the excess will be immediately furnished to the person having made the deposit, and his amount will be due before water service is actually begun. Should the final cost be less than the amount of the deposit or estimate, a refund of overpayment will be immediately made to the person from whom the deposit was received.

§ 78-291 System extensions to serve single customers or groups of independent single customers; assessment policy.

(Code 1975, § 23-67; Ordinance 3368, § 1, adopted 9/14/2015)

Generally.

Title.

This section shall be known as the "Water and Sanitary Sewer System Extension and Assessment Policy Ordinance" of the City of North Richland Hills.

Statement of purpose.

This section sets forth the requirements to be followed in extending public water and sanitary sewer lines to serve a single customer or groups of independent single customers. The requirements under this section are specifically exclusive of extensions for residential subdivisions or commercial developments which are covered in section 78-292.

Sewer system improvements

Definitions.

Benefited property

means a lot or tract to which water or sewer service is made available under this section.

City

means the City of North Richland Hills, Texas.

Cost of improvement

includes construction expense, engineering expenses, fiscal fees, and other expenses incidental to the construction of improvements to the water system, sewer system, or both systems in addition to the other costs of the improvements, including acquisition of right-of-way or easements.

Lien

means the right to take and sell or hold the property of a debtor as security or payment for a debt.

means the laying of mains, laterals, and extensions and all appliances and necessary adjuncts required for the sanitary disposal of sewage from the area in which the improvements are made but does not include off-site mains, laterals, and extensions and appliances and adjuncts necessary to connect the improvements to the existing sewer system operated by the municipality.

Water system improvements

means the laying of a water main with gates, tees, crosses, taps, meter boxes, manholes, or extensions, and any other appurtenances required to furnish water for domestic or commercial purposes to the area in which the improvements are constructed but does not include any off-site appurtenances required to connect the improvements to the existing water system operated by the municipality.

Project determination.

Improvements requested by customer.

One potential customer or a group of single potential customers may request public water or sanitary sewer lines be extended to serve their property. Their request should be made in writing and addressed to the city manager. A petition indicating 50 percent or more of the benefited properties are in favor of the project should accompany the letter of request. The percentage will be based on accumulative linear foot frontage of properties in favor versus total frontage benefited. The letter of request should also include the following items for each customer:

Name.

Address.

Telephone number.

Lot, block, and addition or, if unplatted, tract designation per local tax maps, survey name, and abstract number.

Type and size of service requested.

Preference of service location as measured from property corner along frontage.

Upon receipt of requests, the city manager will have the public works/utilities department review the request. The public works/utilities department will prepare an estimate of cost for the water and/or the sanitary sewer line extensions. The estimate shall include construction costs and an allowance of ten percent of the construction cost estimate for administrative, field survey, and contingency costs. A plan layout of the requested improvements shall accompany the estimate and a list of the benefited properties with their frontage lengths. The estimate and accompanying materials shall be returned to the city manager for presentation to the city council. Depending on availability of funds, the council will authorize or not authorize the city staff to proceed with the detailed construction plans and assessment policy requirements.

Improvements proposed by city staff.

The city staff or as otherwise designated by the city manager can initiate projects to extend public water and/or sanitary sewer lines under the provisions of this section when the improvements will provide service to benefited property and the improvements will enhance the public health and general welfare. The same requirements as stated in subsection (b)(1) of this section will be adhered to.

Assessment policy.

Percentage to be assessed benefited property.

The city council will assess nine-tenths of the estimated cost of improvements against the benefited property and the owners of that property. Any portion of the improvements which is in the "impact fee" calculations as providing for future development will not be included in the assessment against the benefited property.

Apportionment of assessments.

The city shall separately compute the cost of the water or sewer improvements and shall apportion the part of the cost of those improvements that may be assessed against the benefited property and the owners of the property, among the parcels of the benefited property and the owners, in accordance with the front foot rule.

Under the front foot rule, the city shall assess each parcel of benefited property according to the number of lineal feet of the parcel that abuts on a public street, irrespective of the location of improvements constructed under this section relating to that parcel if the improvements provide water or sewer service to the assessed parcel. The city council shall assess a corner lot based on the shorter side of the lot that abuts on a public street.

Procedure of assessment.

The procedure for legally assessing the benefited properties shall be as described in V.T.C.A., Local Government Code § 401.001 et seq., Municipal Water and Utilities, V.T.C.A., Local Government Code § 402.001 et seq. Any subsequent revision to this law will be adhered to from its effective date forward.

Liens.

Notice of improvements.

If the city levies or assesses any of the cost of improvements against the benefited property, the city will file a notice, signed on behalf of the city by the mayor, with the county clerk. The notice must substantially show that the city has determined by order, directive, or otherwise that water or sewer system improvements are necessary; identify the required improvements by location or otherwise; state that a portion of the cost of the improvements is to be or has been specifically assessed as a lien against the benefited property; and describe that property. One notice may contain any number of systems or improvements.

It is not necessary that a notice under this subsection give details or be sworn to or acknowledged. The city may file the notice at any time. The county clerk with whom the notice is filed shall record the notice in the records of mortgages or deeds of trust and shall index it in the name of the city and in the name or other designation of the water or sewer system to which the notice relates.

Amount of interest rate.

An assessment against benefited property under this subsection shall be a lien collectible with interest, cost of collection, and reasonable attorney's fees. The assessment is a first and prior lien on the assessed property, and the lien takes effect on the date that a notice of proposed improvements is made as stated in subsection (c)(4)a of this section. The lien is superior to any other lien or claim except a state, county, school district, or municipal property tax lien. The assessment is a personal liability and charge against the owners of the assessed property on the date on which the lien takes effect, whether or not the owners are named in a notice, instrument, certificate, or ordinance. The city council may prescribe an interest on the assessments not to exceed ten percent a year. The interest on the liens shall begin after the improvements are complete and functional and 30 days after invoices have been mailed to all benefited property owners.

(d)

Payment procedure.

Lump sum.

The assessed amount can be paid any time prior to 30 days after the invoices are mailed out without interest costs. After that time, a lump sum payment may be made and the payment will be applied first to any interest accumulation.

Five-payment payout plan.

Upon written request, the city will allow a benefited property owner to divide his assessment into five equal payments which include the "remaining balance" interest at the rate prescribed by the city council. The first payment to be made within 60 days of the date the invoice was mailed. The subsequent four payments shall be made annually on the anniversary date of the initial payment.

§ 78-292 System extensions to serve subdivision developments.

Nonpayment provision.

If the assessments are not paid, the city will accumulate interest at the maximum rate by law. The lien on the property may be foreclosed upon nonpayment, by action of the city council of the city directing foreclosure.

(Code 1975, § 23-68)

Basic policy and scope of charges.

The developer shall pay all costs attributable to the installation of water and sewerage facilities as are needed to fulfill the basic criteria requirements of the city for service to his subdivision. Such costs generally comprise the following:

Easement or right-of-way cost.

Direct construction cost.

Engineering design and general administration.

Review and handling of plans and contract documents.

Construction layout, cut sheets and field adjustments.

Inspection and acceptance by city.

Fees assessed on others not within the control of the city.

In all cases, the developer furnishes or pays for all easements or rights-of-way, and all fees or assessments by other parties not within the control of the city. Also, in all cases, the developer pays to the city a fee in the amount of four percent of the actual construction cost for which the city reviews the plans and contract documents and performs the inspection and acceptance of the work (subsections (a)(1)d and f of this section).

The developer shall employ his own engineer to furnish the engineering design, general administration, construction layout, cut sheets and field adjustments (subsections (a)(1)c and e of this section) at no cost to the city.

All subdivision extensions shall be covered by a city-developer agreement, which clearly defines the scope and details of the proposed extension and particularly contains the developer's agreement to abide by all regulations of the city and to deliver to the city clear and unencumbered title to all the proposed improvements at the time of acceptance by the city, which must be prior to commencing service.

The city shall participate in the cost of subdivision extensions only where and to the extent that oversized facilities in addition to the subdivision needs are required for the proper overall benefit of the system and when city funds for such oversizing are available. Such oversizing needs shall be determined by the city's engineer with concurrence of the city manager, and shall be authorized only by approval of the city council.

When the city participates in the cost of constructing the project by oversizing facilities, or other participation, the contract for construction shall be executed between the city and the contractor after compliance with all Charter and statutory requirements for advertising and receiving competitive bids. When the city does not participate in the construction costs of the project, the contract for construction may be negotiated between the developer and the contractor of his choice, or, by mutual agreement of the developer and the city manager, bids may be received. In either event, the contract shall be executed between the city and the contractor. The developer will then place in escrow, with the city, funds totaling the amount of the contract plus the appropriate percentage fees as outlined in subsection (a)(1) of this section.

Refunds to the developer shall be made only on applicable situations involving connections to off-site facilities (approach mains) or boundary facilities, and then only when provisions for such refunds are specifically provided for in the city-developer contract executed prior to construction of the extensions.

Methods of procedure.

The developer initiates preliminary action by obtaining copy of applicable portions of policies and procedures from the city. The developer then has his engineer prepare and submit to the director of utilities, who forwards to the city's engineer after a review by the fire chief and director of public works, a preliminary layout of proposed water and sewer extensions superimposed on an approved preliminary plat signed by the city, along with his tentative estimate of costs for the overall development and for the first section if incremental development is proposed.

The city's engineer reviews the proposed preliminary plat and returns to the city with comments and recommendations concerning acceptability and oversizing needed. The city advises developer of tentative approval or necessary changes with copy to city's engineer.

Action toward the filing and improving of all or a portion of development covered by preliminary action as per subsection (b)(1) of this section, is initiated by the developer as follows: The city furnishes the developer with three blank forms of the standard city-developer agreement. Developer's engineer shall prepare and submit to the city complete construction plans, specifications and other necessary contract documents along with estimates of developer's cost and city participation, two blue line prints of the final plat showing approval signatures for the City of North Richland Hills, or City of Watauga if in Watauga. Such documents shall be submitted to city's engineer for review and after they have been fully completed, and are acceptable and approved by the city council, the city shall return them to developer with notice of approval in exchange for the executed city-developer agreement and city's fee of four percent.

If contract is to be let for bid, the developer's engineer prepares and furnishes to the city a notice to bidders to be properly published with bids to be addressed to the city manager and received at the North Richland Hills City Hall.

After selection of the contractor has been accomplished by bids or negotiation as per subsection (b)(2) of this section, the actual construction shall be accomplished as follows:

If bids are received, city engineer receives and recommends award to city manager. If not, developer advises who is contractor and furnishes bid amounts. The city manager or director of utilities notifies developer to have documents executed and returned to the city.

After the work order is issued, the developer's engineer provides the construction layout, staking and prepares cut sheets for all sewers. A copy of all cut sheets shall be furnished to the city's engineer, the director, or inspector and the contractor or as otherwise designated by the city manager. Also, a carbon copy of the actual construction staking field notes shall be furnished to the city's engineer.

The director of inspections or as otherwise designated by the city manager shall inspect the work and review the partial and final pay estimates to the contractor as prepared by the developer's engineer. After pay estimates have been agreed upon by the inspector and the contractor, they shall be transmitted to the city's engineer for checking.

The city's engineer or as otherwise designated by the city manager shall check all pay estimates and after they are in order shall transmit them to the city manager with recommendation for payment or corrections as noted.

After final completion of the work to the satisfaction of the inspector and city engineer or as otherwise designated by the city manager, the city manager shall issue a statement of acceptance of the facilities for ownership and operation by the city to the developer.

Evaluated prices.

When the city participates in the cost of facilities for oversizing or for any other reason, separate bid items shall be set up to reflect the cost to the city when such separate items can be feasibly determined. In the absence of such specific bid prices, the price shall be determined by using a current bid price or city engineer's estimated price.

(d)

Developer payments.

When any extension or improvement to the water and/or sewerage system is to be installed under contract between the city and a contractor, the cost of which is to be paid wholly or partially by a developer, the contractor shall not be authorized to commence work until after the city has received the full amount due from the developer, either in cash to be placed in escrow or by irrevocable commercial letter of credit from a bank or other lending agency acceptable to the city, the conditions of such letter to be included in the city-developer agreement and of form approved by the city attorney.

(e)

Charges and/or refunds on off-site and boundary facilities.

When any customer, whether an individual, residential or commercial customer, builder, developer or any other person, desires a service connection directly to an existing water or sewer line that was previously installed as a boundary or off-site facility of an extension serving another development or other individuals, the charges for each such connection to the line shall be assessed in accordance with the terms of sections 78-290(a) and (b).

§ 78-293 Standard requirements and criteria of design for system extensions.

Where a water or sewer line has been purchased or installed at city expense across or alongside undeveloped property, the subsequent developer of such property shall be assessed for the cost of the line across or alongside his property exclusive of oversizing not needed to serve his subdivision. On water and sewer lines alongside undeveloped property, the assessment shall be apportioned between abutting property owners.

(Code 1975, § 23-69)

Contract documents.

All contract documents for extensions or improvements to the city's water or sewerage facilities shall be prepared under the supervision and bear the seal of a licensed professional engineer, licensed by the state in the field of civil or sanitary engineering, as required by V.T.C.A., Occupations Code § 1001.001 et seq., and shall consist of the following:

Notice to contractor (if applicable).

(8)

General conditions (standard adopted by city).

(9)

Special provisions (by engineer).

(10)

Detailed specifications (standard adopted by city).

(11)

Plans (usually but not always bond separately).

*Note: The city will furnish five copies of the city standard items noted thus * for inclusion in the documents and the developer's engineer will prepare other sections required for complete documents.

Water system design and construction standards.

All materials and workmanship used in extensions or improvements to the city's water system shall conform to the latest revisions of American Water Works Association or American Standards Association specifications and particularly to the most recent revisions of the detailed specifications which have been adopted by the city, a copy of which is on file at the offices of the city and will be made available for inspection upon request. All installations shall be designed and constructed to conform to the latest applicable rules and regulations as published by the state department of health.

Nonrising stem gate valves with slip or screw-type cast iron cover boxes and other control devices shall be installed throughout the system as recommended by the city's engineer for proper control, maintenance and operation of the system. These valves shall be "Mueller" or approved equal.

Standard three-way, improved-type, dry head fire hydrants constructed to provide a minimum of three feet of cover over the connecting main shall be installed at locations such that all areas of single-family development are located within a 500-foot radius from a fire hydrant or all such hydrants will be placed so that hose line routes will be no more than 800 feet by public right-of-way. In the areas other than single-family development, fire hydrants shall be on a 300-foot radius. The area of development shall be defined as the full area delineated by the limits of the approved development plat. These fire hydrants shall be "Mueller" or approved equal.

All fire hydrants shall be installed with a cutoff valve and shall be served by a six-inch or larger supply or distribution main.

All distribution mains from nominal six-inch I.D. to 12-inch I.D. inclusive shall be either ductile iron or PVC in accordance with the standard specifications.

All supply mains and distribution mains installed within a developer's platted and filed area of development must extend to the borders of his development as required for future extension of the city's system, regardless of whether or not such extensions are required for service within the area of development.

(7)

After installation of water lines and curb and gutter the contractor will be required to install all meter boxes to top of curb grade at his own expense. The city will furnish the meter boxes. In addition, the contractor will be required to adjust all valve boxes, fire hydrants, etc., to top of curb grade if the water main is located behind the curb and gutter. Afterwards, the builder or homeowner will be responsible for adjusting valve boxes, fire hydrants, meter boxes, etc., to finished lot grade upon final inspection.

(8)

A $1.00 to $200.00 fine may be levied against any unauthorized person or persons opening or closing a main city water distribution valve without the express permission and supervision of the city utility department.

(9)

Water system extension and improvements shall be designed in accordance with master water and sewer plan.

Sewerage system design and construction standards.

All materials and workmanship used in extensions or improvements to the city's sewerage system shall conform to the latest revisions of the applicable sections of the American Society of Testing Materials standards as prescribed in the latest revision of the detailed specifications which have been adopted by the city, a copy of which is on file at the offices of the city and will be made available for inspection upon request. All installations shall conform to the latest applicable design criteria for sewerage systems as published by the state department of health.

Approach sewers shall be designed with consideration for serving full drainage area subject to collection by the system, but modified as governed by the projected rate of development and the financial feasibility of the proposed extension. Lateral sewers shall be designed to serve the planned area of development with provision for extension where possible into adjacent undeveloped areas.

The population density for undeveloped areas shall be based on surrounding development, but shall not be less than 9.5 persons per acre unless approved otherwise by the city. The contributing sewage flow shall be determined on the basis of an average flow of 100 gallons per person per day without separate provision for infiltration. Outfall sewers, approach sewers and collector sewers shall be designed on the basis of the following peaking factor formula:

Peaking Factor = 1 +	14
	4 + √p;
where:
P = population expressed in thousands.

All lateral sewers or sewer mains installed within a developer's platted and filed area of development must extend to the borders of his development as required for future extensions of the collecting system regardless of whether or not such extensions are required for service within the development.

Detailed determination of the sanitary sewerage area shall be the responsibility of the city. Where there is a question as to the facilities required, it shall be resolved in favor of additional capacity. All construction will be inspected by the city's designated inspector.

The construction of sewage lift or pumping stations or separate treatment facilities will not be permitted unless the costs of constructing such lift stations or separate facilities is at least 30 percent less than the cost of constructing an adequate outfall or approach sewer to serve the area. All estimates of costs for this determination shall be by the city's engineer.
