Amended Sidewalk Construction Ordinance Amendment 3. Zoning Code Amendment ROSS EARNST MEMORANDUM To: Ross Earnst From: Vernon Umetsu RE: SEPA Checklist for Sidewalk Policies Date: June 29, 1987 Pursuant to our conversation last week, Rick Beeler concurs with my determination that adding the sidewalk policies to the City Comprehensive Plan requires a SEPA checklist and that the Public Works Department, as the lead agency, should be responsible for preparing it. We plan to take these policies to the Planning Commission on July 24, 1987. Therefore, we will need to have a completed checklist for review by July 10, 1987. Please do not hesitate to contact me if I can be of further assistance (short of writing the checklist for you). FINDINGS A. Alleviating the need to use autos for short -distance intra -business trips by promoting pedestrian/sidewalk facilities will improve traffic conditions and provide a missing CBD amenity. B. Sidewalks have been constructed where improvements have been made to private property since 1977. Primarily sidewalks have not been constructed adjacent to property developed prior to 1980. C. The City needs a CBD sidewalk system to fulfill the goals of the ordinances and to provide pedestrian links with -transit facilities, recreation areas, and residential neighborhoods. 0. Existing sidewalks, especially those four feet wide or greater should be deemed conforming to standards and should not be required to be upgraded to standards contained in this report unless appropriately incorporated into future street/traffic revisions by the City of Tukwila. E. The pedestrian facilities include informal gravel or grass foot paths adja- cent to the edge of pavement or behind the curb.. and gutter, asphalt shoulders or sidewalks, and concrete sidewalks with a broomed or exposed aggregate finish. F. There were over six pedestrian vehicular collisions between June 6, 1978 and February 28, 1983 in the project area which is a relatively low amount. G. Most employees are pedestrians only infrequently, due to a lack of needed facilities and difficult traffic conditions (based on a business survey). H. The CBD sidewalk system must only provide a network to encourage pedestrian access to and from primary nodes of activity consisting of retail shopping centers, banking facilities, restaurants and hotel/mofels, offices, manufac- turing, warehousing and recreational parks and trail systems. Concentrations of pedestrians will occur at major intersections and not "enroute" as the system does not cater to "window shopping" but to direct access. I. Pedestrian facilities on private properties, where concentrations of pedestrians will continue to be found, must be accommodated by development and improvements to those standards. Those improvements should be con- sistent with the standards developed as part of this -planning process. J. Emphasis must be placed on improvements to provide continuity by constructing missing segments of pedestrian routes rather than declaring existing sidewalks in non-conformance. CENTRAL BUSINESS DISTRICT SIDEWALK PLAN POLICIES GENERAL [GUIDELINES] Policy 1: Tukwila shall create a functional, safe, compatible and convenient sidewalk and pathway system to encourage pedestrian use within the 7 1 Central Business District (CBD). The focal point in improving the �'" "`"' sidewalk system shall be construction of missing sidewalk segments. Policy 2: The sidewalk and pathway system shall [will] provide a network to link various CBD land uses [retail shopping center, banking facilities, restaurants, hotels/motels, officers, manufacturing, warehousing,] with transit centers, recreational parks and trail systems. This system shall provide continuity to link residential neighborhoods with the CBD by providing access to bridges located along the perimeter of the CBD. Policy 3: Tukwila shall improve [amend] its sidewalk system as necessary to provide pedestrian route continuity to bus stops and any future Metro transit sites. FUNDING AND PHASING Policy 4: tTwo alternatives are presented here, representing divergent views on the Transportation Committee.] [Option 11 Sidewalks which are built by the City shall by financed by an area - wide improvement district based on the provisions for a third class City sidewalk improvement district .in R.C.W. 35.70 should be adopted. CENTRAL BUSINESS DISTRICT SIDEWALK PLAN POLICIES Page 2 The City shall [will] be responsible for the design of sidewalks and for the costs of establishing a sidewalk benefit district. Property owners in the CBD shall be encouraged to donate (will be responsible for donating' rights-of-way or easements for sidewalks and for building sidewalks on their property as consistent with City policy. [It shall be the property owner's responsibility to maintain the sidewalks abutting their property.] [Option 2 [A combination of easements, developers' agreements, LIDs and a City allocation of$200,000 per year will be used to pay for sidewalks.] [Policy 5: Business will shall donate rights-of-way or easements on CBD properties for sidewalks. It shall will be the property owner's responsibility to maintain the sidewalks abutting their property.] Policy 6: According to the Tukwila Municipal Code (TMC) [11.64], developers are required to build sidewalks to City specifications in new develop- ments or redevelopment, as defined in the TMC [11.64.020(a)]. An area -wide sidewalk benefit district shall [will] require all those property owners who do not currently have sidewalks where sidewalks are planned, to either build their sidewalks to City specifications, or be assessed for the cost of building their sidewalks. The City's contribution will be the design of the sidewalks and the cost of administering the L.I.D. CENTRAL BUSINESS DISTRICT SIDEWALK PLAN POLICIES Page 3 [Comment: An area -wide improvement district based on the provisions for a third class City sidewalk improvement district in R.C.W. 35.70 should be adopted.] Policy 7: The City of Tukwila and private property owners shall mutually strive to finish construction of the sidewalk system recommended in the sidewalk plan within seven years according to the following schedule: a. As properties develop or redevelop in accordance with the Tukwila Municipal Code [T.M.C. 11.64], sidewalks shall [will] be con- structed by the developer or property owner at no cost to the City. b. New street construction and street widening will include sidewalks as shown on the adopted [in the] Sidewalk Ilan. c. In 1988, [a program is planned to] construct the sidewalks on Southcenter Parkway and on one side of the very high priority streets in the Sidewalk Plan. d. The sidewalks remaining to be built on the very high priority streets shall [will] be constructed in 1989. e. Sidewalks on one side of •the high priority streets in the Sidewalk Plan will be constructed in 1990. f. The remaining sidewalks on high priority streets shall [will] be constructed in 1991. CENTRAL BUSINESS DISTRICT SIDEWALK PLAN POLICIES Page 4 g. Moderate priority sidewalks in the sidewalk plan shall [will] be constructed over the following three years. Policy 8: Temporary sidewalks shall be allowed at such locations as the final grade of the adjacent street has not been determined and where future lane widening or traffic improvements, as identified in the City Capital Improvement Plan, will replace the sidewalk within 5 years. Temporary sidewalks shall be constructed using two-inch compacted depth of asphaltic concrete Class B on prepared subgrade. SIDEWALK DESIGN Policy 9: New sidewalks in retail/commercial/office zoned areas will be six feet wide. Sidewalks in all other CBD [distribution warehouse] zoned areas will be five feet wide percent of the primary use is of a retail/commercial/office nature, at which time sidewalks will be six feet wide. At bus stops and o pullouts, the speed limit is over 35 mph land) where a.trail and sidewalk are combined, sidewalks shall be a minimum of eight feet wide. Policy 10: Where full inclusion of a sidewalk is not feasible the design will be adapted to the available space through joint planning by the Planning and Public Works Directors. Policy 11: Existing sidewalks that are a minimum of four feet wide shall be deemed to be acceptable by the City. Sidewalks which are less than • • CENTRAL BUSINESS DISTRICT SIDEWALK PLAN POLICIES Page 5 the standard five or si'xfeet''and-wfrio#r are= badly cracked, crumbling or uneven, as determined by the Director of Public Works, shall be replaced in sections/blocks by standard size sidewalks at no cost to the City. Comment: There are currently few four foot sidewalks in the City, and they are not heavily used by pedestrians. Where a section of sidewalk is crumbling, the replacement should be made on a block basis or in a long enough section to assure route continuity and fit. Policy 12: Sidewalks and traffic intersection designs will be coordinated to accommodate both pedestrians,handicap curb cuts, and the largest allowable vehicles on the streets. Handicap access to sidewalks will be provided at intersections and driveways. Safety and traffic standards in the [Transportation] Comprehensive Plan will be met. CONFORMANCE TO CITY STANDARDS [PoIicy:13: For existing developments, sidewalks built on donated rights-of-way or easement will be credited as part of the donating property owner's landscape and setback requirements. through exceptions variances in the zoning code.] [Policy 14: Sidewalks built on donated easements on existing developments on private property will be included as part of the donating property owner's landscape requirements under the City's zoning code.] • CENTRAL BUSINESS DISTRICT SIDEWALK PLAN POLICIES Page 6 Policy : Where the donation of easements or right-of-way for sidewalks in existing developments causes them to fall below City landscaping or building setback standards, the donated area may be counted satisfying these requirements. This allowance shall cease upon building replacement, at which time all City ordinances shall be met. Policy 15: Where sidewalks would interfere with existing parking [stalls,] the sidewalk design will be modified by the Directors of Public Works and Planning to accommodate sidewalks with -minimum impacts on park- ing. Minimum impacts shall include restriping and use of compact stalls to retain the existing number of parking spaces. CROSSWALKS AND MID -BLOCK CROSSINGS Policy 16: Streets with sidewalks may require mid -block crossings with traffic signals. Such crossings shall be built when an engineering study shows it is needed and feasible. The study shall be triggered by the following criteria: * At least 300 feet between crossings. * A minimum pedestrian volume of 300 people/hour at least 4 hours/day. * Traffic analysis determines that signal timing and traffic progression can be maintained. A gap delay of 30 seconds in traffic volume on an arterial street is acceptable. 411 CENTRAL BUSINESS DISTRICT SIDEWALK PLAN POLICIES Page 7 Policy 17: Painted crosswalks will not be provided where sidewalks do not exist. Pedestrians have the right-of-way at all marked crosswalks and unmarked crossings at intersections. Policy 18: At existing signalized intersections pedestrian signal controls and crossings shall [will] be included at the time sidewalks are constructed. Policy 1': Crosswalks will be marked at all CBD signalized intersections with sidewalks to indicate pedestrian route continuity. [Intersections will be signed to caution the pedestrian to cross only with the proper pedestrian signal control._s.equence.] All—new CBD signal control equipment where sidewalks exist must incorporate pedestrian signal controls and signs.
