Per Renton Municipal Code (RMC) 4-6-060, the following would be required on Monster Rd SW: • 17 feet of right-of-way (ROW) dedication, • 11 -foot center turn lane, • 8 feet of sidewalk, • 8 -foot planter strip, • Curb and gutter 10 -foot travel lane, • 5 -foot bike lane, and • 8 -foot parking lane on both sides. Frontage improvements are required by Renton Municipal Code for projects that exceed $50,000 in value. However, RMC 4-9-250(C) allows for a waiver of the requirements subject to the criteria below. a. Required street improvements will alter an existing wetlands or stream, or have a negative impact on a shoreline's area. There are no wetlands or streams along Monster Road SW frontage property. b. Existing steep topography would make required street improvements infeasible. Much of the property frontage along Monster Road SW is located within a regulated or steep slope making additional frontage improvements infeasible. In areas where there is no regulated steep slope, there is an existing curb/gutter and five -foot -wide sidewalk providing pedestrian connectivity which meets the intent of the City's Comprehensive Plan and Municipal Code. King County Department of Natural Resources and Parks Wastewater Treatment Division Environmental and Community Services Section King Street Center, KSC-NR-0505 201 South Jackson Street Seattle, WA 98104-3855 c. Required street Improvements would have a negative impact on other properties, such as restricting available access. In order to construct complete streets along Monster Road SW, the roadway would need to be shifted west within the right of way, which would impact the properties on the west side of the right of way, or large walls would need to be constructed on the east side of the roadway reducing the existing vegetation along the roadway. d. There are no similar improvements in the vicinity and there is little likelihood that the improvements will be needed or required in the next ten (10) years. There is an existing five -foot -wide sidewalk along the east side of the Monster Road SW. In areas along Monster Road SW, where there is no sidewalk adjacent to the regulated steep slope, the pedestrian needs are met by an existing public 10 -foot -wide asphalt pedestrian path that traverses the steep slope along Monster Road SW. Because of the adjacent sensitive areas and provided pedestrian sidewalks and pathway, it is unlikely that improvements will be needed in the next ten years. e. In no case shall a waiver be granted unless it is shown that there will be no detrimental effect on the public health, safety or welfare if the improvements are not installed, and that the improvements are not needed for current or future development. Existing pavement width and existing pedestrian sidewalks and pathway provide for safe vehicular and pedestrian travel.
