Chapter 6
STREET AND UTILITY STANDARDS

CHAPTER GUIDE: The development-related requirements for water, sewer, storm drainage and street construction are contained in chapter 4-6 RMC. Fee-related information for developers and builders (i.e., utility fees, including system charges) is found in chapter 4-1 RMC. Permit application submittal and review requirements (e.g., public works permits, etc.) are located in chapter 4-8 RMC. Non-development-related utility and street regulations (e.g., monthly stormwater service fees or garbage collection procedures, and others) are found in RMC Title 8 or 9.

This Chapter last amended by Ord. 5413, October 13, 2008.

4-6-010 GENERAL STANDARDS APPLICABLE TO DEVELOPER EXTENSIONS TO THE UTILITY SYSTEM:

A. CONDITIONS AND STANDARDS FOR CONSTRUCTING UTILITY EXTENSIONS:

The City’s Utility Division shall publish from time to time a “Conditions and Standards for Constructing Utility Developer Extensions”. All developer extensions shall abide and fully comply with said Standards. From time to time these Standards shall be updated in accordance with the “Standard Specifications for Municipal Public Works Construction of the American Public Works Association”, “Recommended Standards for Sewage Work”, the American Water Works Association (AWWA) Standards, Insurance Services Office (ISO) requirements, the American Public Works Association (APWA) Standards and with prevailing good practices relative to such extension and installations. (Ord. 3056, 8-9-1976 and Ord. 3055, 8-9-1976, eff. 7-1-1976)

B. MAINS TO EXTEND FULL WIDTH OF PROPERTY:

All extensions shall extend to and across the full width of the property served with water and sewer. No property shall be served with City water or sewer unless the main is extended to the extreme boundary limit of said property line extending full length of the front footage of said property. (Ord. 2849, 5-13-1974)

1. Special Exception for Sanitary Sewer Extensions: All installations shall extend to and across the full width of the property served with sanitary sewer except when it is shown by engineering methods, to the satisfaction of the wastewater utility, that future extension of the sewer main is not possible or necessary. If an exemption is granted, the property owner is not relieved of the responsibility to extend the main and shall execute a covenant agreeing to participate in an extension if, in the future, the wastewater utility determines that it is necessary. (Ord. 4343, 2-3-1992)

C. OVERSIZING OF UTILITIES AND REIMBURSEMENT BY CITY:

If it has been determined that it would be to the best interests of the City and the general locality to be benefited thereby to install a larger size main than one then needed or considered by the subdivider, owners or developers immediately abutting upon the street, alley or easement in which such a main is to be placed, then the City may, at its discretion, require the installation of such a larger sized main in which case the City shall pay the increased difference in cost between the installation cost of the similar main and of the larger main. (Ord. 2849, 5-13-1974)

Any party required to oversize utilities may request that utility participate in the cost of the project. (Ord. 4506, 4-10-1995 and Ord. 4415, 8-16-1993)

4-6-020 CROSS CONNECTION CONTROL STANDARDS:

A. PURPOSE:

1. National standards of safe drinking water have been established. The City, as a water purveyor, has the primary responsibility for preventing water from unapproved sources, or any other substances, from entering the public potable water system. (Ord. 4312, 5-13-1991)

2. This Section is to protect the health of the water consumer and the potability of the water in the distribution system. This is accomplished by eliminating or controlling all actual (direct) and potential (indirect) cross connections between potable and nonpotable systems through the use of approved backflow prevention assemblies.

B. APPLICABILITY:

This Chapter applies throughout the water service area of the City. It applies to all systems installed prior to or after its enactment. Therefore, anyone wanting or using water from the City is responsible for compliance with these regulations and shall be strictly liable for all damage incurred as a result of failure to comply with the express terms and provisions contained herein.

C. AUTHORITY:

The Administrator of the Department of Planning/Building/Public Works will administer the provisions of the Chapter. He/she will designate cross connection specialists and propound all needful rules and regulations to implement these provisions. The Water Utility Section of the Utility Systems Division will be responsible for monitoring and inspecting all existing cross connection assemblies and for keeping all records generated by the cross connection control program. The Plan Review Section of the Development Services Division will be responsible for reviewing all new and revised plans for cross connections.

D. INSTALLATION OF BACKFLOW PREVENTION ASSEMBLIES:

Backflow prevention assemblies required by this Chapter must be installed so as to be readily accessible for maintenance and testing. All assemblies shall be connected at the meter, the property line when meters are not used, or within any premises where, in the judgment of the City Cross Connection Control Specialist, the nature and extent of activity on the premises or the materials used or stored on the premises could present a health hazard should a cross connection occur. This includes:

1. Premises having an auxiliary water supply.

2. Premises having internal cross connections that are not correctable, or intricate plumbing arrangements which make it impractical to ascertain whether or not cross connections exist.

3. Premises where entry is restricted so that inspections for cross connections cannot be made with sufficient frequency or at sufficient short notice to assure that cross connections do not exist.

4. Premises having a repeated history of cross connections being established or re-established.

5. Premises on which any substance is handled under pressure so as to permit entry into the public water system, or where a cross connection could reasonably be expected to occur. This includes the handling of process waters and cooling waters.

6. Premises where materials of a toxic or hazardous nature are handled such that if backsiphonage should occur, a health hazard may result.

7. Hospitals, mortuaries, clinics.

8. Laboratories.

9. Piers and docks.

10. Sewage treatment plants.

11. Food or beverage processing plants.

12. Chemical plants using a water process.

13. Metal plating industries.

14. Petroleum processing or storage plants.

H. BONDS AND LIABILITY INSURANCE REQUIRED:

The Development Services Division shall require all persons constructing retention/detention facilities to post with the Administrator surety and cash bonds or certified check in the amount of one and one-half (1-1/2) times the estimated cost of con-

struction. Where such persons have previously posted, or are required to post, other such bonds with the Administrator, either on the facility itself or on other construction related to the facility, such person may, with the permission of the Director and to the extent allowable by law, combine all such bonds into a single bond; provided, that at no time shall the amount thus bonded be less than the total amount which would have been required in the form of separate bonds; and provided further, that such bond shall on its face clearly delineate those separate bonds which it is intended to replace.

1. Construction Bond: Prior to commencing construction the person constructing the facility shall post a construction bond in an amount sufficient to cover the cost of conforming said construction with the approved drainage plans. In lieu of a bond, the applicant may elect to establish a cash escrow account with his bank in an amount deemed by the Administrator to be sufficient to reimburse the City if it should become necessary for the City to enter the property for the purpose of correcting and/or eliminating hazardous conditions relating to soil stability and/or erosion. The instructions to the escrowee shall specifically provide that after prior written notice unto the owner and his failure to correct and/or eliminate existing or potential hazardous conditions and his failure to timely remedy same, the escrowee shall be authorized without any further notice to the owner or his consent to disburse the necessary funds unto the City of Renton for the purpose of correcting and/or eliminating such conditions complained of. After determination by the Department that all facilities are constructed in compliance with the approved plans, the construction bond shall be released.

2. Maintenance Bond: After satisfactory completion of the facilities and release of the construction bond by the City, the person constructing the facility shall commence a three (3) year period of satisfactory maintenance of the facility. A cash bond, surety bond or bona fide contract for maintenance with a third party for the duration of this three (3) year period, to be approved by the Administrator and to be used at the discretion of the Administrator to correct deficiencies in said maintenance affecting public health, safety and welfare, must be posted and maintained throughout the three (3) year maintenance period. The amount of the cash bond or surety bond shall be in the amount of one and one-half (1-1/2) times the estimated cost of maintenance for a three (3) year period.

3. Liability Policy: The person constructing the facility shall maintain a liability policy during such private ownership with policy limits of not less than one hundred thousand dollars ($100,000.00) per individual, three hundred thousand dollars ($300,000.00) per occurrence and fifty thousand dollars ($50,000.00) property damage, which shall name the City of Renton as an additional insured without cost to the City and which shall protect the City of Renton from any liability, cost or expenses for any accident, negligence, failure of the facility, omission or any other liability whatsoever relating to the construction or maintenance of the facility. Said liability policy shall be maintained for the duration of the facility by the owner of the facility, provided that in the case of facilities assumed by the City of Renton for maintenance pursuant to subsection I of this Section, said liability policy shall be terminated when said City maintenance responsibility commences.

I. CITY ASSUMPTION OF MAINTENANCE:

1. Maintenance of Facilities by City Authorized: The City of Renton is authorized to assume the maintenance of retention/detention facilities after the expiration of the three (3) year maintenance period in connection with the subdivision of land if:

a. All of the requirements of subsection F of this Section have been fully complied with;

b. The facilities have been inspected and approved by the Department after their first year of operation;

c. The surety bond required in subsection H of this Section has been extended for one year covering the City’s first year of maintenance;

d. All necessary easements entitling the City to properly maintain the facility have been conveyed to the City;

e. It is recommended by the Administrator and concurred in by the City Council that said assumption of maintenance would be in the best interests of the City.

2. Notification of Defect Required: The owner of said property shall throughout the maintenance period notify the City in writing if any defect or improper working of the drainage system has come to his notice. Failure to so notify the City shall give the City cause to reject assumption of the maintenance of the facility at the expiration of the three (3) year maintenance period, or within one year of the discovery of the defect or improper working, whichever period is the latest in time.

J. RETROACTIVITY RELATING TO CITY MAINTENANCE OF SUBDIVISION FACILITIES:

If any person constructing retention/detention facilities and/or receiving approval of drainage plans prior to the effective date of this Section re-assesses the facilities and/or plans so constructed and/or approved and demonstrates, to the Administrator’s satisfaction, total compliance with the requirements of this Section the City may, after inspection, approval and acknowledgment of the proper posting of the required bonds as specified in subsection H of this Section, assume maintenance of the facilities. (Ord. 3174, 11-21-1977)

K. DRAINAGE PLAN REVIEW PROCEDURES:

The drainage plan and supportive calculations shall be reviewed by the Department using the Department’s construction plan review procedures in coordination with all other applicable City permit review procedures.

1. Tests: Whenever there is insufficient evidence of compliance with any of the provisions of this Code or evidence that any material or construction does not conform to the requirements of this Code, the Administrator may require tests as proof of compliance to be made at no expense to this jurisdiction. Test methods shall be as specified by this Code or by other recognized test standards. If there are no recognized and accepted test methods for the proposed alternate, the Administrator shall determine test procedures. Suitable performance of the method or material may be evidence of compliance meeting the testing requirement. (Ord. 4269, 5-21-1990)

2. Half Street Improvements:

a. When Permitted: Half street improvements may be allowed for a residential access street by the Administrator or her/his designee when it is determined

that the adjacent parcel of property has the potential for future development and dedication of the right-of-way necessary for the completion of the street right-of-way.

b. Minimum Design Standards: The right-of-way for the half street improvement must be a minimum of thirty-five feet (35') with twenty-eight feet paved (28'). A curb and a six-foot (6') sidewalk shall be installed on the development side of the street. If the street will require a cul-de-sac, then the right-of-way for the half of the cul-de-sac shall be dedicated, with installation of a temporary hammerhead turnaround. The property shall also dedicate easements to the city for street lighting and fire hydrants. Additional easements shall be provided for the franchise utilities outside of the dedicated right-of-way.

c. Standards for Completion of the Street: When the adjacent parcel is platted or developed, an additional fifteen feet (15') of right-of-way shall be dedicated from the developing property. The pavement shall then be widened to thirty two feet (32') in total width, and a curb and six foot (6') wide sidewalk shall be installed on the developing side of the street. If the street is a dead end street requiring a cul-de-sac, then the developing parcel shall dedicate the remainder of the right-of-way for the cul-de-sac and construct the final complete cul-de-sac, including curb and sidewalk improvements.

3. Reduced Right-of-Way Dedication:

a. When Permitted: The Department may approve a reduction in the required right-of-way width for residential access streets for new streets within a short plat or subdivision to forty two feet (42') when the extra area from the reduction is used for the creation of an additional lot(s) which could not be platted without the reduction; or when the platting with the required right-of-way width results in the creation of lots with less than one hundred feet (100') in depth.

b. Additional Easements: The Department may require additional easements be provided for the franchise utilities outside of the dedicated right-of-way when such a right-of-way reduction is approved. In no case shall a reduction in the required right-of-way width be approved unless it is shown that there will be no detrimental effect on the public health, safety or welfare if the right-of-way width is reduced, and that the full right-of-way width is not needed for current or future development.

S. DEFERRAL OF IMPROVEMENT INSTALLATION:

See RMC 4-9-060.

T. APPEALS:

Any decisions made in the administrative process described in this Section may be appealed to the Hearing Examiner pursuant to RMC 4-8-110.

U. VIOLATIONS OF THIS SECTION AND PENALTIES:

Unless otherwise specified, violations of this Chapter are misdemeanors subject to RMC 1-3-1. (Ord. 4521, 6-5-1995; Ord. 5159, 10-17-2005)

4-6-070 TRANSPORTATION CONCURRENCY REQUIREMENTS:

A. AUTHORITY AND PURPOSE:

This Chapter is enacted pursuant to the Washington State Growth Management Act, chapter 36.70A, at RCW 36.70A.070. It is the purpose of this Chapter to ensure Renton transportation level of service standards are achieved concurrently with development, or within a reasonable time after development occupancy and use. (Ord. 4708, 3-2-1998)

B. DEFINITIONS OF TERMS USED IN THIS SECTION:

1. Concurrency or Concurrent with Development: Transportation improvements or strategies are in place at the time of building permit issuance, or a financial commitment is in place to complete the improvements or strategies within six (6) years of building permit issuance.

2. Department: The Planning/Building/Public Works Department.

3. Development Activity Permit Application: For the purposes of transportation concurrency regulations, any construction, building expansion, or change in use which creates additional demand upon or need for transportation facilities and which requires a development permit from the City of Renton.

4. Development Permit: Written permission from the appropriate City decision maker authorizing the division of a parcel of land, the construction, reconstruction, conversion, structural alteration, relocation or enlargement of any structure, or any use or extension of the use of the land.

5. Financial Commitment: Includes revenue designated in the most currently adopted Transportation Improvement Program for transportation facilities or strategies through the six (6) year period with reasonable assurance that such funds will be timely put to such ends, unanticipated revenue from Federal or State grants for which the City has received notice of approval, and/or revenue that is assured by an applicant in a form approved by the City in a voluntary agreement.

6. Finding of Concurrency: A written finding that is part of the applicable development permit issued by the City indicating that a development activity permit application has successfully passed the Renton transportation concurrency test. The finding of concurrency is made by the decision maker with the authority to approve the development permit.

7. Level of Service (LOS): A measure of the quality and efficiency of facilities and systems. The Renton transportation LOS is adopted in the Renton Comprehensive Plan Transportation Element. The transportation LOS standard establishes an index value which must be met or exceeded in future years. The LOS index value is determined by the weighted sum of the p.m. peak travel distances from the City, averaged in all directions, in thirty (30) minutes for SOV, HOV, and transit modes. The current index value is forty nine (49). More in depth discussion of the Citywide LOS policy may be found in the Transportation Element.

8. Transportation Concurrency Test: Technical review of a development activity permit application by the Department to determine if the transportation system has adequate or unused or uncommitted capacity, or will have adequate capacity, to accommodate trips generated by the proposed development, without causing the level of service standards to decline below the adopted standards, at the time of development or within six (6) years.

9. Vested: The right to develop or continue development in accordance with the laws, rules, and other regulations in effect at the time vesting is achieved. The time vesting is achieved is determined in accordance with brightline vesting rules included in State legislation and case law.

C. APPLICABILITY AND EXEMPTIONS:

1. Applicability: A concurrency test shall be conducted for all development activity applications, as defined in subsection B3 of this Section, excluding exemptions.

2. Exemptions: The following applications are exempt from the concurrency test:

a. Applications categorically exempt from SEPA review under RMC 4-9-070, Environmental Review Procedures.

i. The concurrency test shall not be conducted for projects that are subject to SEPA review due to their location within an environmentally sensitive area, but which would otherwise be exempt from SEPA review.

ii. The concurrency test exemption shall not apply to short plats.

b. Any project that is a component of a development which was granted a finding of concurrency that has not expired.

c. Development vested prior to April 6, 1998.

d. Projects granted a finding of concurrency where the development activity is conducted by a person or entity other than the original applicant, if the project is limited to the uses, intensities, and vehicle trip generation rates for which the finding of concurrency was originally made.

D. CONCURRENCY REVIEW PROCESS:

1. Test Required: A concurrency test shall be conducted by the Department for each nonexempt development activity. The concurrency test shall determine consistency with the adopted Citywide Level of Service Index and Concurrency Management System established in the Transportation Element of the Renton Comprehensive Plan, according to rules and procedures established by the Department. The Department shall issue an initial concurrency test result describing the outcome of the concurrency test.

2. Written Finding Required: Prior to approval of any nonexempt development activity permit application, a written finding of concurrency shall be made by the City as part of the development permit approval. The finding of concurrency shall be made by the decision maker with the authority to approve the accompanying development permits required for a development activity. A written finding of concurrency shall apply only to the specific land uses, densities, intensities, and development project described in the application and development permit.

3. Failure of Test: If no reconsideration is requested, or if upon reconsideration a project fails the concurrency test, the project application shall be denied by the decision maker with the authority to approve the accompanying development activity permit application.

E. TRANSFERABILITY OF WRITTEN FINDING OF CONCURRENCY:

1. A written finding of concurrency is not transferable to other land, but may be transferred to new owners or lessees of the original land.

2. Revisions to an approved development that may create additional impacts on transportation facilities will be required to undergo an additional concurrency test. A new finding of concurrency is required from the decision maker with the authority to approve the revised project in order to permit the revised development activity.

3. Revisions to an approved development that reduce the intensity or density or vehicle trip generation rates of the project, resulting in less impacts to transportation facilities than originally approved, will be required to undergo an additional concurrency test in order to properly account for unused capacity. Unless the revised development requires newly issued development permit approvals, the previous finding of concurrency remains in effect, and a new finding of concurrency is not required for the less intense or dense proposal.

F. EXPIRATION OF WRITTEN FINDING OF CONCURRENCY:

A finding of concurrency shall expire if the accompanying development permit expires or is revoked. A finding of concurrency may be extended according to the same terms and conditions as the accompanying development permit. If the development permit is granted an extension, the finding of concurrency shall be extended simultaneously for the same period. If the accompanying development permit does not expire, the finding of concurrency shall be valid for a period of three (3) years from the date the written finding was made.

G. RECONSIDERATION OF CONCURRENCY TEST:

1. Notification Required: Prior to a final recommendation or decision to deny a development activity permit application due to failure of the concurrency test, the Department shall notify the project applicant in writing of the initial concurrency test results.

2. Reconsideration Authorized: The Department shall allow an applicant of a development activity that has failed an initial concurrency test to request an administrative reconsideration of the concurrency test results or prepare a modified project submission.

3. Timing: Requests for reconsideration shall be made in writing within ten (10) calendar days of the Department’s written notification. Requests for reconsideration shall be directed to the Department Administrator, and be filed with the Development Services Division counter no later than 5:00 p.m. of the tenth day.

4. Options to Achieve Concurrency: The Department shall allow an applicant to submit alternative data, provide a traffic mitigation plan, or reduce the size of the project in order to achieve concurrency.

5. One Hundred Twenty (120) Day Time Limit Suspended: Upon receipt of a request for reconsideration, the one hundred twenty (120) day permit review time limit established in RMC 4-8-080E, Permit Classification Time Frames, shall be suspended temporarily until the decision date to allow an applicant to prepare any supplemental information, and to allow Department review of the request for reconsideration and data submitted.

H. APPEAL OF PROJECT APPLICATION DENIAL:

1. A project applicant may appeal the denial of a development activity based upon failure of a concurrency test. The appeal shall be based upon one or both of the following grounds:

a. Technical error; or

b. The applicant submitted alternative data or a traffic mitigation plan that was rejected by the City.

2. If the development activity requires a Type I, II, or III permit as defined in chapter 4-8 RMC, the decision to deny a finding of concurrency may be appealed to the Hearing Examiner for an open record appeal. The decision of the Hearing Examiner may be appealed to the City Council for a closed record appeal.

3. If the development activity requires a Type V or VI permit as defined in chapter 4-8 RMC, the decision to deny a finding of concurrency may be appealed to the City Council for a closed record appeal, or the Shoreline Hearings Board, as appropriate.

4. If the development activity requires a Type IV, VII, VIII, IX or X permit as defined in chapter 4-8 RMC, the decision to deny a finding of concurrency may be appealed to Superior Court.

I. CONCURRENCY INQUIRY:

1. An applicant may inquire whether or not there is sufficient capacity available to accommodate a development without submitting a development application.

2. Available capacity cannot be reserved based on a preliminary inquiry.

3. A written finding of concurrency will only be issued in conjunction with a development activity permit application. (Ord. 4708, 3-2-1998)

K. INSTALLATION OF SERVICE PRIOR TO COMPLETION OF STREET CONSTRUCTION:

Whenever it is deemed prudent, in case of a new development or subdivision, to install the three-fourths inch (3/4") service from the main to the property line, hereinafter referred to as “stub service” prior to completion of street construction, the City will provide such service for sixty percent (60%) of the then current installation cost for such service. At such time that meter installation is requested, the remaining balance of the then current rate shall be collected and paid for by such developer or subdivider. (Ord. 4287, 8-13-1990)

4-6-090 UTILITY LINES – UNDERGROUND INSTALLATION:

A. PURPOSE:

It is especially found and determined by the City that the health, safety, especially the safety of the traveling public, and general welfare of the residents of the community require that all such existing overhead facilities be relocated underground as soon as practicable in accordance with the requirements specified herein and that all new facilities specified herein be installed underground. The purpose of this Chapter, among others, is to

establish minimum requirements and procedures for the underground installation and relocation of electrical and communication facilities within the City.

B. APPLICABILITY:

It shall be and it is hereby made the policy of the City to require compliance with the following orderly program pertaining to the underground relocation of all existing overhead wires carrying any electrical energy, including, but not limited to, telephone, telegraph, cable television and electrical power, and to require the underground installation of all new electrical communication facilities, subject to certain exceptions noted hereafter. Subject to the excepted facilities listed in subsection C of this Section, this Chapter shall apply to all electric facilities and to all communication facilities, including but not limited to telephone, telegraph and cable television facilities.

C. EXEMPTIONS:

1. This Chapter shall not apply to the following facilities:

a. Electric utility substations, pad-mounted transformers and switching facilities not located on the public right-of-way where site screening is or will be provided in accordance with subsection H7b of this Section.

b. Electric transmission systems of a voltage of fifty five (55) kv or more, (including poles and wires) and equivalent communication facilities where the utility providing electrical energy is willing to provide at its expense an underground street lighting circuit including all conductor and conduit to a point on the poles at least forty feet (40') above ground level to serve utility owned street lighting fixtures to be mounted on the poles at said location.

c. Ornamental street lighting standards.

d. Telephone pedestals and other equivalent communication facilities.

e. Police and fire sirens, or any similar municipal equipment, including traffic-control equipment. (Ord. 2432, 9-23-1968)

f. When undergrounding is required due to extensions, duplications, relocations or rebuilds to existing overhead electrical and communication facilities but the poles to be removed following undergrounding would not be removed because of continuing requirements for such poles, such as services to residences of King County when those residences are not required to be undergrounded. However, if there is a reasonable likelihood that undergrounding would occur in the foreseeable future, conduit for underground crossings should be installed whenever feasible as part of any ongoing street construction, reconstruction or overlayment project.

g. When:

undergrounding is required due to extensions, duplications, relocations or rebuilds to existing overhead electrical and communication facilities and there are existing overhead electrical or co
