It is the purpose of this Section to establish design standards and development requirements for street improvements to ensure reasonable and safe access to public and private properties. These improvements include appropriately scaled sidewalks related to the urban context, a range of landscape buffers, curbs, gutters, street paving, monumentation, signage, and lighting, to be developed with complete streets principles. Complete streets principles are to plan, design, and operate streets to enable safe and convenient access and travel for all users including pedestrians, bicyclists, transit riders, and people of all ages and abilities, as well as freight and motor vehicle drivers, and to foster a sense of place in the public realm with attractive design amenities. (Ord. 4521, 6-5-1995; Ord. 5517, 12-14-2009)

B. ADMINISTERING AND ENFORCING AUTHORITY:

The Community and Economic Development Administrator is responsible for the general administration and coordination of this section. (Ord. 5450, 3-2-2009; Ord. 5517, 12-14-2009; Ord. 5676, 12-3-2012)

C. APPLICABILITY:

The standards in this section will be used for all public and private street improvements within the City of Renton. Whenever a building permit is applied for or application made for a short plat or a full subdivision, the applicant for such permit and/or application shall build and install certain street improvements, including, but not limited to: lighting on all abutting rights-of-way, and all private street improvements on access easements. The minimum design standards for streets are listed in the tables set forth in subsection F2 of this Section. These standards will determine specific street improvement requirements for development projects, including short plats and subdivisions. (Ord. 5450, 3-2-2009; Ord. 5517, 12-14-2009; Ord. 5676, 12-3-2012)

D.  EXEMPTIONS:

The following exemptions shall be made to the requirements listed in this Section:

1. New construction or addition with valuation less than one hundred seventy five thousand dollars ($175,000.00) (the value of which shall be reviewed in conjunction with mandatory periodic updates of the Comprehensive Plan and based on the Seattle Construction Cost Index).

2. Interior remodels of any value not involving a building addition.

3. If demonstrated as necessary to mitigate an extreme hardship not caused by the requestor. (Ord. 5676, 12-3-2012; Ord. 5703, 12-9-2013; Ord. 5867, 12-11-2017; Ord. 5907, 12-10-2018; Ord. 6128, 12-11-2023)

E. RIGHT-OF-WAY DEDICATION REQUIRED:

	NOTES AND CONDITIONS: MINIMUM DESIGN STANDARDS TABLE FOR PUBLIC STREETS AND ALLEYS: 1    Minimum design standards may be altered to allow alternative stormwater management and low impact development techniques within the R-O-W by the Department. 2    Sidewalk width will be 12 feet on both sides in the City Center Community Planning Area. This sidewalk width includes street tree grates for locating street trees. To accomplish low impact development best management practices, permeable pavement may be allowed by the Administrator. 3    Sidewalk areas may be required at a wider width to accommodate required multi-use path facilities when a Class I multi-use path is required within a street R-O-W by the Department. The width of a required 5-foot bicycle lane will be transferred to the sidewalk area to create a Class I multi-use path. To accomplish low impact development best management practices permeable pavement may be allowed by the Administrator. 4    Maintenance Responsibilities. Unless otherwise agreed upon by the City of Renton, maintenance of landscaping within the planting strip area, including but not limited to elements such as groundcover, turf, softscape, and hardscape, is the responsibility of the adjacent property owner. Maintenance for street trees within the public right-of-way shall be the responsibility of the City of Renton. 5    Planting strips may be reduced if one of the following conditions is met: (a) when R-O-W acquisition is problematic; or (b) when critical areas would be impacted. If approved, a permanent alternative landscaped area should be provided equal to or greater than the allowed planting strip area reduction that is in addition to any minimum existing code requirements. 6    A second parking lane may be required by the Administrator. 7    Class II bicycle facilities (bike lanes) included in roadway width for both sides. Bicycle facilities that are shared travel lanes, Class III bicycle facilities, require less roadway width. Class III travel lanes are a minimum of 14 feet.
	8    Requirement: Either fire sprinklers shall be provided as approved by the Fire Department or a clear roadway area shall be provided for emergency vehicles midblock. All of the clear area must be 20 feet in width for vehicular movement with a minimum length of 50 feet and maximum length of 100 feet, so as to provide emergency access to homes within 150 feet. Along the clear area only, the planting strip would not be required and the clear area will be in place of the landscaping area. 9    The City may require different lane width dimensions to address safety concerns or to meet state and federal requirements for state routes or grant funding. 10    Turning radius dimensions represent the vehicle turning path. The smallest curb radius should be used while maintaining the specified turning radius. Lane width and the presence of a bike lane and parking lane affect a vehicle’s turning path. On streets with more than one lane in that direction of travel, large vehicles may encroach into no more than one-half of the adjacent travel lane to complete the turn. On Arterials and Collector Arterials, encroachment into oncoming travel lanes is unacceptable. The minimum curb radius is 15 feet. 11    Turning radius for streets which include industrial access may increase to 50 feet. 12    Sidewalks shall be provided on both sides of the street; however, the Administrator may approve sidewalks on one side of the street pursuant to RMC 4-6-060G. 13    Sidewalks may be designed to be reverse sloped away from the street; provided, that the sidewalks have a maximum long slope of 2% and are designed to drain towards a publicly owned low impact development facility along the roadway instead of directly into the street.

A curb, planting strip area, and sidewalk shall be installed on the development side of the street according to the minimum design standards for public streets. If the street is permitted 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 Half Street: When the adjacent parcel is platted or developed, the additional right-of-way width needed to complete the type of street classification shall be dedicated from the developing property. The pavement shall then be widened to the width needed to complete the type of street classification, and curb, planting strip, and 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, sidewalk, and other required improvements. (Ord. 5517, 12-14-2009)
