(Ord. 1309 § 5(part), 2003)

20.60.110 - Determining compliance with Section 20.60.100.

(a)

Primary responsibility for determining whether a proposed development will comply with the standard set forth in Section 20.60.100 (Sewage Disposal Facilities Required) may lie with an agency other than the city, and the developer must comply with the detailed standards and specifications of such other agency. The relevant agencies are listed in Subsection (b). Whenever any such agency requires detailed construction or design drawings before giving its official approval to the proposed sewage disposal system, the authority issuing a permit under this chapter may rely upon a preliminary review by such agency of the basic design elements of the proposed sewage disposal system to determine compliance with Section 20.60.100 (Sewage Disposal Facilities Required). However, construction of such system may not be commenced until the detailed plans and specifications have been reviewed and any appropriate permits issued by such agency.

(b)

In the following if-then list, the if statement describes the type of development and the then statement indicates the agency that must certify to the city whether the proposed sewage disposal system complies with the standard set forth in Section 20.60.100 (Sewage Disposal Facilities Required).

(1)

If: The use is located on a lot that is served by a public sewer system and the use can be served by a connection to the system (as in the case of a single family residence) rather than the construction of an internal collection system (as in the case of a shopping center or apartment complex):

Then: No further certification is necessary.

(2)

If: The use (other than a subdivision or short plat) is located on a lot that is served by the city sewer system but service to the use necessitates construction of an internal collection system (as in the case of a shopping center or apartment complex); and the internal collection system is to be transferred to and maintained by the city:

Then: The public works director must certify to the city that the proposed internal collection system meets the city's specifications and will be accepted by the city.

(3)

If: The use (other than a subdivision or short plat) is not served by the city system but, pursuant to Section 20.60.120 (Private Sewage Disposal), is qualified to be served by a privately operated sewage treatment system (that has not previously been approved) designed to serve one equivalent residential unit (ERU):

Then: The Snohomish County Health District (SCHD) must certify to the city that the proposed system complies with all applicable state and local health regulations.

(4)

If: The proposed use is a subdivision or short plat; and

(A)

Lots within the subdivision or short plat are to be served by connection to existing public lines:

Then: No further certification is necessary.

(B)

Lots within the subdivision or short plat are to be served by the city system but the developer will be responsible for installing the necessary additions to the public sewer system:

Then: The public works director must certify to the city that the proposed system meets the city's specifications and will be accepted by the city.

(C)

Lots within the subdivision or short plat are, pursuant to 20.60.120 (Private Sewage Disposal), qualified to be served by independent sewage treatment systems:

Then: The Snohomish County Health District must certify that the proposed system complies with all applicable state and local health regulations and that the lot can be served by an on-site disposal system.

(a)

Primary responsibility for determining whether a proposed development will comply with the standard set forth in Section 20.60.300 (Water Supply System Required) often lies with an agency other than the city, and the developer must comply with the detailed standards and specifications of such other agency. The relevant agencies are listed in Subsection (b). Whenever any such agency requires detailed construction or design drawings before giving its official approval to the proposed water supply system, the authority issuing a permit under this chapter may rely upon a preliminary review by such agency of the basic design elements of the proposed water supply system to determine compliance with Section 20.60.300 (Water Supply System Required). However, construction of such system may not be commenced until the detailed plans and specifications have been reviewed and any appropriate permits issued by such agency.

(b)

In the following if-then list, the if statement describes the type of development and the then statement indicates the agency that must certify to the city whether the proposed water system complies with the standard set forth in Section 20.60.300 (Water Supply System Required).

(1)

If: The use is located on a lot that is served by the city of Arlington water system or a previously approved, privately owned public water supply system and the use can be served by a simple connection to the system (as in the case of a single family residence) rather than the construction of an internal distribution system (as in the case of a shopping center or apartment complex):

Then: No further certification is necessary.

Even in the event the distribution line originates from a point opposite any public roadway from the new construction the service lines shall be placed beneath said roadway by means of boring or surface excavation across said roadway.

(b)

Building permits for additions, alterations, or repairs within any twenty-four-month period and equal to less than fifty percent of the total value of the existing building or structure shall not be subject to the requirements of this section.

(c)

If it is determined that an underground system cannot reasonably be installed according to accepted engineering practices, the requirements of this section may be waived upon receipt of a written notice from the appropriate utility service provider. Similarly, this requirement may be waived for small in-fill developments where the majority of the utilities along the street are still above ground and little more development is anticipated. In either case, such a waiver shall be noted in the permit or shall be construed as not being granted. If undergrounding of utilities is waived, the applicant must sign either a concomitant agreement or a no protest agreement of the formation of an L.I.D. for future undergrounding. Determination of which form of promissory shall be used shall be at the discretion of the community and economic development director. Additionally, the developer shall install the appropriate conduit for future undergrounding of the utilities in the appropriate place.

(d)

Nothing in this section nor any other section in relation to underground utilities shall apply to power lines carrying a voltage of one hundred fifteen kV or more (transmission lines), nor shall it be construed to prohibit the placement of said mounted transformers, terminal pedestal, or other electrical and communications devices above ground, as determined by the appropriate utility service provider involved, except for subsection (e) below.

(e)

All new development following the Mixed-Use Development Regulations is required to underground all utilities as listed in (a) above, along with transmission lines along all street frontages shall either be undergrounded or re-routed to the rear side of the buildings or property. The placement of all mounted transformers, terminal pedestal, or other electrical and communications devices that are proposed above ground shall be placed at the rear side of the building/property. The applicant shall provide a proposed utility plan to the city and obtain approval from the community and economic development director and/or his/her designee. The final utility plan shall be approved with the civil permit.

(Ord. 1309 § 5(part), 2003; Ord. No. 2022-024, § 2, 10-17-2022; Ord. No. 2025-007, § 1, 6-16-2025)

New utility transformer boxes shall not be placed along the public street frontage or between the public right-of-way and buildings in the commercial corridor or mixed-use overlay zone. In the commercial corridor and mixed-use overlay zones the applicant shall work with the city and the public utility district to determine an approved location prior to installation of electrical power lines to the site and be approved on the civil plans.

(Ord. No. 2025-007, § 2, 6-16-2025)

20.60.460 - Utilities to be consistent with internal and external development.

(a)

Whenever it can reasonably be anticipated that utility facilities constructed in one development will be extended to serve other adjacent or nearby developments, such utility facilities (e.g., water or sewer lines) shall be located and constructed so that extensions can be made conveniently and without undue burden or expense or unnecessary duplication of service. The public works director shall approve the location. In all cases, utility lines shall extend to the common property line(s) of the subject property and the property(ies) anticipated to undergo future development.

(b)

All utility facilities shall be constructed in such a manner as to minimize interference with pedestrian or vehicular traffic and to facilitate maintenance without undue damage to improvements or facilities located within the development.

Every development that, under the city's solid waste collection policies, is or will be required to provide one or more dumpsters for solid waste collection shall provide sites for such dumpsters that are:

(1)

Located so as to facilitate collection and minimize any negative impact on persons occupying the development site, neighboring properties, or public rights-of-way, and

(2)

Constructed according to specifications established by the public works director to allow for collection without damage to the development site or the collection vehicle.

(b)

All such dumpsters shall be screened if and to the extent that, in the absence of screening, they would be clearly visible to:

(1)

Persons located within any dwelling unit on residential property other than that where the dumpster is located; or,

(2)

Occupants, customers, or other invitees located within any building on nonresidential property other than that where the dumpster is located, unless such other property is used primarily for purposes permitted exclusively in a light industrial or industrial zoning district; or,

(3)

Persons traveling on any public street, sidewalk, or other public way.

When dumpster screening is required under this section, such screening shall be constructed, installed, and located to prevent or remedy the conditions requiring the screening, per Chapter 20.46 (Design Standards).
