A.    The purpose of this chapter is to promote sound development guidelines and construction procedures which respect and observe the city’s watercourses; to minimize water quality degradation and control the sedimentation of creeks, streams, ponds and other water bodies; to protect property owners adjacent to developing and developed land from increased runoff rates which could cause erosion of abutting property; to protect downstream owners; to preserve and enhance the suitability of waters for recreation; to preserve and enhance the aesthetic quality of the waters; to maintain and protect ground water resources; to minimize adverse effects of alterations in ground water quantities, locations and flow patterns; to ensure the safety of public roads and rights-of-way; and to decrease drainage-related damage to public and private property.

B.    This chapter is enacted pursuant to the police power of the city to protect and preserve the public health, safety and general welfare and in compliance with the Federal Clean Water Act (Title 33 United States Code Section 1251 et seq.) and the requirements of the city’s National Pollution Discharge Elimination System (NPDES) Phase II permit issued by the Washington State Department of Ecology. Its provisions shall be liberally construed to accomplish the purposes of the program and the protection and preservation of the public health, safety and general welfare.

C.    It is the intent of this chapter to provide for and to promote the public health, safety and general welfare of the citizens and not to create or otherwise establish or designate any particular class or group of persons who will or should be specially protected or benefited. This chapter shall not be construed to create any specific rights in any individual nor to create any duty owed by the city toward any individual or class of persons.

D.    It is the intent of this chapter to place the obligation of compliance with the requirements of this chapter upon the owner and/or operator of a stormwater facility, whether public or private. Nothing contained in this chapter is intended to be nor shall it be construed to create or form the basis for liability on the part of the city, or its officers, employees or agents, for any injury to persons or damage to property resulting or arising from the act, omission or failure of the owner or operator of any stormwater facility to comply with the provisions of the program, or by reason or in consequence of any act or omission in connection with the implementation or enforcement of this chapter by the city, or their officers, employees or agents.

No latecomer’s agreement shall be legally effective until the city council adopts an ordinance approving the latecomer’s agreement at a public meeting of the city council. All applications for latecomer’s agreements shall be made on the basis that the applicant releases and waives any claims for any liability of the city in the establishment and enforcement of any latecomer’s agreements. The city shall not be responsible for locating any beneficiary or survivor entitled to benefits by or through latecomer’s agreements.

D.    Application Requirements. All applications, procedures and policies for latecomer’s agreements shall be approved and established by the mayor or his/her designee, and shall be accompanied by all nonrefundable application fees set forth in the city’s land use fee schedule or in any fee schedule subsequently adopted by the city. The latecomer’s agreement application must be submitted for city review prior to city acceptance of the improvements for which reimbursement is sought.

E.    Eligibility of Applicants. In order to be eligible to apply for a latecomer’s agreement, the applicant shall be in compliance with all city ordinances, rules and regulations relating to any development application or project associated with the proposed latecomer’s agreement.

F.    Procedures for Latecomer’s Agreements.

1.    The applicant (developer) proposing to establish a latecomer’s agreement shall submit a preliminary estimate and proposed reimbursement/benefit area (“benefited area”) boundaries as part of the engineering drawings submitted as part of the initial project application. Following utility/street installation/construction and city acceptance of same, the applicant (developer) requesting a latecomer’s agreement shall submit detailed construction plans and drawings for the project together with a site plan, map or diagram of the proposed benefited area which documents shall be prepared and stamped by a licensed professional civil engineer and which shall identify the proposed boundaries of the benefited area and each separately owned parcel of real property located within the benefited area and the location of the project in relation to all parcels of real property located within the benefited area, and an itemized cost estimate for the entire project based upon the plans of the civil engineer from which reimbursable costs shall be estimated, together with assessor’s reports (including names and mailing addresses) of all real properties within the benefited area, and such other information and documents as the city may require.

2.    The applicant (developer) requesting a latecomer’s agreement shall submit, along with the application, the nonrefundable application fee set forth in the city’s land use fee schedule, which application fee shall be applied to the city’s legal, engineering and administrative costs in processing the application for the latecomer’s agreement, which costs shall be included as reimbursable costs in the latecomer’s agreement; provided, that whenever the city’s actual engineering, legal, administrative or other costs exceed the amount of the initial nonrefundable application fee, the applicant shall be required to pay to the city the estimated cost of said excess costs and the city shall not be obligated to continue to process the application until such costs have been paid to the city in full. In addition, the city will charge an eight percent administrative fee for handling each transaction, said fee to be deducted from all latecomer’s fees collected.

3.    The mayor or his/her designee will determine the boundaries of the benefited area based upon a determination of which parcels of real property are within the benefited area and which of such parcels will not contribute to the original cost of street and utility system improvements and who may subsequently connect to, drain to or use the same including uses connected to laterals or branches connecting thereto.

4.    The mayor or his/her designee, based on information submitted by the applicant with the application for the latecomer’s agreement, will establish an estimate of the pro rata share of costs. The director or his designee may require the applicant to supply the city with engineering costs and/or competitive construction bids prior to the establishment of the estimate.

5.    The director or his/her designee, at his/her discretion, shall have the right to require the applicant to pay, in advance, the costs of an appraiser retained by the city to assist the director or his designee in formulating the assessment reimbursement area and the estimate of the proration of costs.

6.    Prior to the execution of a contract with the applicant for a latecomer’s agreement, the mayor or his designee shall deliver by certified mail a notice required by the applicable state law to all property owners within the benefited area stating the preliminary boundaries of the benefited area and pro rata share of assessments for costs of the project, and stating that each property owner has the right to request a public hearing to be held before the city council to consider the application for the latecomer’s agreement, including the preliminary boundary of the benefited area and preliminary assessment of costs to the affected property owners. If no hearing is requested, the city council may consider and take final action on the latecomer’s agreement at any public meeting held more than twenty days after notice was mailed to the affected property owners. If the city receives a request for a public hearing, a public hearing will be held by the city council thereafter, with notice of the public hearing given to all affected property owners at least twenty days in advance of the hearing. At the hearing, the city council shall determine whether to accept, reject or modify the proposed latecomer’s agreement, or any provision thereof, including but not limited to the boundaries or proration of costs. If the city council accepts the latecomer’s agreement, the council shall establish the boundaries of the benefited area; provided, that the city council may only modify the boundary of the benefited area upon prior notice to the owners of the property affected by the modification. The decision of the city council shall be final and determinative.

7.    The latecomer’s agreement shall have no legal effect and shall be null and void unless it is recorded with the Snohomish County auditor within thirty days of the final execution of the agreement. It shall be the sole responsibility of the applicant for the latecomer’s agreement to record said agreement at his/her expense.

8.    Once recorded, the latecomer’s agreement shall be binding on all owners of record of all real properties located within the benefited area who are not party to the latecomer’s agreement.

9.    Every two years from the date the contract is executed a property owner entitled to reimbursement under this section shall provide the appropriate county, city, or town with information regarding the current contract name, address, and telephone number of the person, company, or partnership that originally entered into the contract. If the property owner fails to comply with the notification requirements of this subsection within sixty days of the specified time, then the contracting county, city, or town may collect any reimbursement funds owed to the property owner under the contract. Such funds must be deposited in the capital fund of the county, city, or town.

10.    The city reserves the right to participate in these agreements.

11.    The city shall neither issue a building permit nor similar development permit or approval unless the city has received full payment of the assessment applicable to the property connecting to or using the street and/or utility system improvements constructed by the applicant (developer); provided, if the validity of the latecomer’s agreement is challenged, the city reserves the right to issue a permit, approval or permission without liability or prejudice to the city, and without prejudice to any other rights or remedies available to the applicant (developer) under this section or otherwise at law or in equity.

12.    Segregation. The director shall, upon the request of any property owner within the benefited area, segregate the assessment among portions of a particular parcel that is legally subdivided. The segregation shall be based upon the same factors applied when the assessments were originally established. The property owner seeking segregation of the assessment shall pay all costs to record the segregation as well as an administrative fee to the city based upon a segregation fee schedule to be established by the city from time to time.

The director may require an applicant to provide additional information at the applicant’s expense, including but not limited to an engineer’s report or analysis.

2.    Criteria for Granting Exception. The property owner shall bear the burden of proof for any requested exception. In order to grant the exception, the director or other reviewing body must find that application of the minimum requirements imposes a severe and unexpected economic hardship on the project applicant. The director or other reviewing body must also make written findings of fact including the following:

a.    The current (pre-project) use of the site; and

b.    How the application of the minimum requirement(s) restricts the proposed use of the site compared to the restrictions that existed prior to the adoption of the minimum requirements; and

c.    The possible remaining uses of the site if the exception were not granted; and the uses of the site that would have been allowed prior to the adoption of the minimum requirements; and

d.    A comparison of the estimated amount and percentage of value loss as a result of the minimum requirements versus the estimated amount and percentage of value loss as a result of requirements that existed prior to adoption of the minimum requirements; and

e.    The feasibility for the owner to alter the project to apply the minimum requirements; and

f.    The exception will not increase risk to the public health and welfare, nor be injurious to other properties in the vicinity and/or downstream, and to the quality of the waters of the state; and

g.    The exception is the least possible exception that could be granted to comply with the intent of the minimum requirements.

3.    Type I decisions regarding exceptions to the stormwater minimum requirements may be appealed to the hearing examiner according to the appeals process in Chapter 17.13. (Ord. 1390 § 1 (Exh. A) (part), 2016: Ord. 1222 § 2 (Exh. A) (part), 2009)
