A. 
Purpose. It is the purpose of this section to establish design standards and development requirements for street improvements to provide for reasonable and safe access to public and private properties. These improvements include appropriately scaled sidewalks and landscape buffers related to the urban context, curbs, gutters, street paving, monumentation, and lighting, consistent with complete streets principles and fostering a sense of place in the public realm through attractive design amenities.
B. 
Exemptions. Exemptions to this section shall be authorized by the Community and Economic Development Director for development comprised of the following:
1. 
New construction or addition with valuation less than 50 percent of assessed value that occurs or is permitted within any three-year period;

The construction of one single-family house, including two accessory dwelling units, or the modification of or addition to an existing house; provided, that the lot on which a new house would be constructed is not part of a subdivision that occurred within the previous three years.
C. 
Right-of-Way Dedication Required.
1. 
Dedication Required for Development. Where the existing width for any right-of-way adjacent to a development site is less than the City's minimum standards, additional right-of-way dedication to provide an easement for roadway and public use will be required for the proposed development.
2. 
Waiver of Dedication. The Community and Economic Director, in consultation with the City Engineer, may waive the requirement for up to one-half of the right-of-way dedication needed to accommodate a full street right-of-way where he/she determines that either: (a) future development is reasonably feasible on the opposite side of the right-of-way from the site being developed and such future development can reasonably provide for the additional required right-of-way; or (b) due to geographic constraints, future development is not reasonably feasible on the opposite side of the right-of-way being developed.
D. 
Public Street Right-of-Way Design Standards.
1. 
Type of Improvements. The required minimum street improvements shall include but not be limited to curbs, gutters, landscape buffers, sidewalks, and lighting on each side of the street, except as provided under subsection D.2 of this section. Required improvements shall be designed and constructed in conformance with this chapter and other applicable statutes.
2. 
Unless required by another chapter of the Zoning Code, the requirement for amenity zones, landscape buffers, sidewalks, and lighting on either or both sides of a street may be waived by the City Engineer for development projects where he/she has determined that geographic constraints make installation not reasonably feasible or there is no need, including future need, for pedestrian access or circulation. For City-initiated street, sidewalk, or utility projects, the City Engineer may waive the requirement for amenity zones, landscape buffers, sidewalks, and lighting on either or both sides of the street pursuant to the criteria in subsection E.3 of this section.
3. 
Length of Improvements. Improvements required per subsection D.1 of this section shall extend along the full frontage of such property to be improved upon and sought to be occupied as a building site or parking area for the aforesaid building or platting purposes, and which may abut property dedicated as a public street. For properties with multiple street frontages, all frontages must be improved to the City's standards. Improvements shall be transitioned to existing facilities immediately outside of the property's street frontage; provided, that the Reviewing Official may waive this requirement where such a transition is not reasonably feasible or where future development is not likely to occur due to geographic constraints.
4. 
Minimum Sidewalk Measurements and Features. Sidewalks shall be a minimum of six feet wide and constructed of concrete unless another material has been approved by the City Engineer for the specific location; provided, that in certain zoning districts, as required by the Municipal Code or adopted design standards, sidewalk width shall be greater than six feet.
a. 
Where vertical obstructions less than seven feet in height occur, a minimum of four feet of horizontal clearance from the obstruction is required for pedestrian passage.
b. 
Bulb-outs may be required by the City's Transportation Engineer at street intersections, including but not limited to intersections where vehicle parking is allowed nearby, and at mid-block crossings, based on at least one of the following criteria: (i) the bulb-out will increase safety for the pedestrian attempting to cross the street at an intersection or marked crosswalk; or (ii) the bulb-out location is consistent with guidance from a referenced standard pursuant to MTMC § 19.95.010E. In addition, bulb-outs may be required by zoning district regulations.
c. 
Any pedestrian facilities, including curb ramps and pedestrian push buttons, immediately adjacent to or contained within the project boundaries shall be replaced with ADA-compliant pedestrian facilities.
d. 
Any curb ramp constructed must have an ADA-compliant companion ramp at the other side of the crossing. If there is an existing ramp at the other side of the crossing that does not meet current ADA criteria, the project will be required to remove and replace it with an ADA-compliant ramp.
5. 
Amenity zones shall be installed between the street curb and sidewalk or multi-use path, except where the City Engineer determines that amenity zones are not reasonably feasible due to geographic or right-of-way constraints. Amenity zones shall include grass or low-growing vegetation; provided, that in the Town Center, as well as along arterials and collectors in other areas approved by the City Engineer, the amenity zones may consist primarily of hardscape, rather than vegetation, and with trees protected in tree grates. Amenity zones shall be at least five feet in width; provided, that up to a two-foot reduction may be allowed where the full five-foot width is not reasonably feasible due to geographic or right-of-way constraints.
6. 
Multi-Use Paths. A minimum 12-foot-wide multi-use path may be installed along streets in place of the minimum six-foot sidewalk path where the City Engineer has determined that such a multi-use path would best accommodate a bicycle route that has been identified in the Comprehensive Plan and where pedestrian safety can be maintained.
7. 
Driveways. Driveway locations and dimensions are subject to requirements of the zoning district in which the driveways are located, pursuant to this title and other requirements of the City Code and state or federal statutes, and to traffic engineering criteria including roadway functional classifications, traffic volumes, sight distance, proximity to intersections and driveway spacing.
8. 
Bicycle Facilities. Bicycle facilities may be provided or required by the City in the form of bicycle lanes within the street, cycle tracks, multi-use paths, or any means indicated in the Comprehensive Plan or the Transportation Master Plan or approved by the City Engineer.
9. 
Vehicular Access and Connection Points to and From the State Highway System.
a.

The Department will also prioritize maintenance of crosswalks, bike lanes, and other pavement markings, commensurate with available resources.
3. 
Exceptions. Complete streets principles, including the provision of amenity zones, will not apply:
a. 
To repairs made to the right-of-way;
b. 
To ordinary maintenance activities designed to keep assets in serviceable condition (e.g., mowing, cleaning, spot repair, and surface treatments including but not limited to chip seal treatments, or interim measures for detours, haul routes, and street closures);
c. 
To improvements solely for traffic signals or signage; provided, that such improvements shall consider the needs of pedestrians and bicyclists, as well as motorists, including mass transit users; or
d. 
Where the City Engineer, after consultation with the Community and Economic Development Director, issues a documented site-specific exception concluding that application of complete streets principles is unnecessary or inappropriate because:
i. 
It would be contrary to public safety or to requirements of a grant or law;
ii. 
The cost is excessively disproportionate to the project or possible use;
iii. 
The City cannot feasibly attain the additional right-of-way that would be needed;
iv. 
Other available means or factors indicate an absence of need, including future need; or
v. 
The City Council has directed that complete streets principles not be applied due to other special factors for a particular street or street segment.
4. 
Exceptions authorized under subsection E.3 of this section are site-specific and shall not constitute general changes to the minimum street standards established in this chapter or other chapters of the Municipal Code.
5. 
Timing and Funding. Complete streets may be achieved through single projects or incrementally through a series of smaller improvements or maintenance activities over time. Improvements to pedestrian and bicycle facilities shall be a priority for available funding, while balancing the need to meet other City responsibilities.
F. 
Street Design Standards. Streets and associated facilities, including but not limited to sidewalks, shall be designed in accordance with the City Engineering Development Manual and consistent with the Comprehensive Plan.
G. 
Access Improvements Required.
1. 
When nonresidential zoned property does not have frontage on an existing public right-of-way or when the City has identified a potential new street connection in its Comprehensive Plan to access nonresidential zoned property but the street has not yet been constructed, any development or change in use shall require the owner/developer to design and construct full-width street improvements through the property and to a point of appropriate connection with an existing public right-of-way. The improvements shall be designed so as to establish an interconnected network of public streets and shall be constructed in accordance with this chapter and any other applicable City regulations and state or federal laws.
2. 
Once a street is constructed pursuant to subsection G.1 of this section, the property owner shall dedicate the right-of-way and its improvements to the City.
H. 
Private Streets – When Permitted.
1. 
Streets designed or constructed after November 1, 2012, shall be public and built to City standards; provided, that the Community and Economic Development Director may allow local access streets serving three or fewer single-family houses to be private when he/she determines that:
a. 
Geographic constraints or other practical difficulties would make City maintenance reasonably impractical; or
b. 
No existing or future need exists for additional traffic and/or pedestrian connections or to serve adjacent property.
2. 
Signage Required. Appurtenant traffic control devices including installation of traffic and street name signs shall be provided by the developer to mitigate traffic impacts, as required by the Traffic Engineer. The street name signs shall include a sign labeled "Private Street."

a. 
Street is constructed to City standards; or
b. 
Street is classified as an arterial or collector (or meets criteria for being so classified) and assumption of maintenance does not create an undue burden for the City.
9. 
Any research performed by the City at an applicant's request to establish or verify that a street has been constructed to City standards, pursuant to subsection H.8.a of this section, is subject to the applicant's payment to the City of the hourly rate established in the development fee schedule, as adopted by the City Council.
I. 
Timing for Installation of Improvements. No building shall be granted a certificate of final occupancy, or plat or short plat recorded, until all the required street improvements are constructed in a satisfactory manner and approved by the responsible departments unless those improvements that remain unconstructed have been deferred by the Department of Community and Economic Development Director subject to security devices authorized under Chapter 15.35 MTMC.

The required traffic impact analysis shall identify any street improvements that may be needed to reduce transportation impacts from the development and to improve nonmotorized transportation facilities related to the development. The City Engineer or designee, in consultation with the Traffic Engineer, may require that the TIA include an evaluation of any potential traffic and parking impacts from the development on arterial or local access streets. The City Engineer or designee is authorized to adopt administrative policies and technical procedures specifying the contents and scope of the TIA, the methodologies to be used in preparing a TIA, and the nature and extent of the improvement(s) necessary to meet the requirements of this chapter.
2. 
Level-of-Service Policy. The City shall maintain or achieve the level of service (LOS) adopted in the Transportation Element of the Comprehensive Plan.
3. 
Development Mitigation Obligations. Frontage improvements, including the upgrading of substandard frontage improvements, will be required of all proposed developments, pursuant to this chapter.
The City Engineer or designee shall require mitigation of direct traffic impacts of any development as provided in this section. Mitigation of off-site impacts to City streets will be in the form of transportation impact fees pursuant to Chapter 18.30 MTMC; provided, that mitigation of site-specific impacts to the City's transportation system also may be required under the State Environmental Policy Act (SEPA) for impacts that are not associated with the transportation impact fees. Such SEPA mitigation may be required on arterial streets, collectors, or local access streets. Mitigation of off-site impacts to state highways or other jurisdiction streets may also be required, as specified in this chapter. Development may have the option to provide mitigation for off-site impacts directly by constructing the improvements that offset the direct traffic impact of the development. Development mitigation requirements may be reduced by the City Engineer or designee if the development implements transportation demand management and/or transportation system management strategies to the extent such strategies would reduce off-site traffic impacts not associated with the transportation impact fees.
4. 
Inadequate Road Condition(s).
a. 
A development's access onto a public road shall be designed so as not to create or aggravate an inadequate road condition. Developments shall be designed so that inadequate road conditions are not created.
b. 
Mitigation of direct project impacts resulting in inadequate road conditions is required. If such conditions are found to be existing in the development's road system at the time of development application review, and the development shall put through the identified locations at the time of full occupancy of the development 10 or more vehicle trips during the weekday peak hours of 4:00 p.m. to 6:00 p.m. or 40 or more vehicle trips during any weekday or 50 or more vehicle trips during any weekend day, the development shall only be approved if provisions are made in accordance with this chapter for improving the inadequate road conditions.
B. 
Total Mitigation Limits. The total amount of off-site improvement cost for which a development is responsible is limited to the development's proportionate fair share amount for mitigation of its impacts on the transportation and right-of-way system. An applicant who volunteers to pay and/or construct more than their share of the road system mitigation may apply for a street assessment reimbursement agreement. Said applicant shall agree to participate in applicable transportation improvement districts.
C. 
Transportation Impact Fees. The applicant for any development activity shall be required to pay transportation impact fees required pursuant to Chapter 18.30 MTMC.
D. 
SEPA Mitigation – City Streets. The applicant for any development activity shall be required to provide mitigation identified through a SEPA review process, except as otherwise provided by this section. Such mitigation may include site-specific access and safety improvements, mitigation of impacts to neighborhood or local access streets, or improvements to nonmotorized transportation systems. Such mitigation may be identified as part of the traffic impact analysis pursuant to subsection A.1 of this section.
E. 
Mitigation – State Highways. Mitigation requirements for impacts on state highways and at intersections of City roadways with state highways may be established by the Washington State Department of Transportation (WSDOT) rather than by the provisions of this chapter.
F. 
Mitigation – Other Jurisdictions. When a development activity may adversely impact the roadway facilities of other jurisdictions, the City Engineer or designee shall forward the traffic impact analysis or other information to the affected jurisdiction for review and comment.
G. 
Mitigation – Administration.
1. 
Timing of Determination. The determination of developer obligations shall be made by the City before approval of all short plats, preliminary subdivisions, planned unit developments, site development plans, conditional and special use permits, and binding site plans or before the issuance of a building permit, whichever occurs first.
2. 
Administration of Payments. Payments made pursuant to this section, excluding subsection C of this section, shall be subject to the following provisions:
a. 
The payment is required prior to issuance of a building permit or commencement of on-site development, whichever occurs first, unless the development is a subdivision, wherein the payment is required prior to the recording of the subdivision.
b. 
The payment and accrued earnings shall be held in a reserve account and shall be expended to fund improvements on the road system, including any nonmotorized transportation facilities, as specified in a written agreement between the developer and the City.
c. 
Payments made pursuant to this section shall include an amount to reimburse the City for the costs of administration of this section, as so provided in a fee resolution adopted by the City Council.

A. 
Authority and Purpose. This section is enacted pursuant to the Washington State Growth Management Act, Chapter 36.70A RCW, at RCW 36.70A.070. The purpose is to require that the Mountlake Terrace transportation level of service standards are achieved concurrently with development, or within a reasonable time after development occupancy and use.
B. 
Development shall not be approved if the development would cause the level of service on a locally owned transportation facility to decline below the standards adopted in the Transportation Element of the City’s Comprehensive Plan unless transportation improvements or strategies to accommodate the impacts of development are made concurrent with the development. “Concurrent” means, for purposes of this section, that improvements or strategies are in place at the time of development or that a financial commitment is in place to complete the improvements or strategies within six years.
C. 
Strategies. Strategies that may be used pursuant to subsection B of this section may include increased public transportation service, ride-sharing programs, demand management and other transportation system management strategies, as approved by the City Engineer or designee to mitigate the transportation impacts of the development.
D. 
Analysis of transportation impacts from development shall be conducted under the authority of the City Engineer or designee pursuant to MTMC § 19.95.080.
(Ord. 2597 § 2, 2012; Ord. 2863 § 1 (Exh. A), 2024; Ord. 2911, 3/5/2026)
If a conflict exists between this chapter and either the Engineering Development Manual or the Comprehensive Plan, this chapter shall control.
