PUBLIC WORKS TRAFFIC DIVISION (Soma Chattopadhyay, PE) soma.chattopadhyay@cityoffederalway.com Transportation Concurrency Analysis (FWRC 19.90) 1. Based on the submitted materials for thirty five new single family dwelling units, the Institute of Transportation Engineers (ITE) Trip Generation - 10th Edition, land use code 210 (Single Family Detached Housing), the proposed project is estimated to generate approximately 36 new weekday PM peak hour trips and 406 daily weekday trips. Alternatively, the applicant may submit a site- specific trip generation study for the proposed development. 2. A concurrency permit is required for this development project. The PW Traffic Division will perform concurrency analysis to determine if adequate roadway capacity exists during the weekday PM peak period to accommodate the proposed development. Please note that supplemental transportation analysis and concurrency mitigation may be required if the proposed project creates an impact not anticipated in the six-year Transportation Improvement Plan (TIP). 3. The estimated fee for the concurrency permit application is $5,167 (11 - 50 Trips), This fee is an estimate and based on the materials submitted for the pre-application meeting. The concurrency applicant fee must be paid in full at the time the concurrency permit application is submitted with land use application. The fee may change based on the new weekday PM peak hour trips as identified in the concurrency trip generation. The applicant has the option of having an independent traffic engineer prepare the concurrency analysis consistent with City procedures; however, the fee remains the same. Transportation Impact Fees (TIF) (FWRC 19.91) 1. Based on the submitted materials for proposed 35 new single-family lots the estimated total traffic impact fee is $259,234.50 ( $ 7407/single family). The actual fee will be assessed and collected from the applicant when the building permit is issued, using the fee schedule then in effect (FWRC 19.100.070 3(c)). At any time prior to building permit issuance, the applicant may request to defer to final building inspection the payment of a transportation impact fee for a single-family residential dwelling unit (FWRC 19.100.075). If this option is selected, a covenant prepared by the city to enforce payment of the deferred fees will be recorded at the applicant’s expense. Refer to defer payment of impact fee code for process. Street Frontage Improvements (FWRC 19.135) 1. Based on the available records and the submitted materials, it appears that this proposal meets the 25 percent threshold criteria for requiring street frontage improvements as identified in the FWRC 19.135.030. The applicant/owner may submit an appraisal for the subject property, or King County Assessor’s records may be used. The Public Works Development Services Division will evaluate the submitted appraisal data to determine if the project actually meets the City’s 25 percent threshold for requiring street frontage improvements. 2. The applicant/owner would be expected to construct street improvements consistent with the planned roadway cross-sections as shown in Map III-4 in Chapter III of the Federal Way Comprehensive Plan (FWCP) and Capital Improvement Program (CIP) shown as Table III-10 (FWRC 19.135.040). Based on the materials submitted, staff conducted a limited analysis to determine the required street improvements. The applicant would be expected to construct improvements on the following streets to the City’s planned roadway cross-sections:  Military Rd S is a Minor Arterial planned as a Type “K” street, consisting of a 44-foot street with curb and gutter, six-foot planter strips with street trees, 8-foot sidewalks, and street lights in a 78-foot right-of-way (ROW). Assuming a symmetrical cross section, 9- foot ROW dedication and half street improvements are required as measured from the street centerline. However, additional eleven-foot will be reserved as Tract X to extend middle lane for future use. If any direct plat access is granted from the Military Rd, the middle lane should be extended as a frontage improvement.  Internal Streets shall be Type “W” public streets, consisting of a 28-foot street with curb and gutter, four-foot planter strips with street trees, five-foot sidewalks and street lights in a 52-foot right-of-way (ROW).  The 30–foot road. easement (Tract X) south of parcel number 1521049101 needs to be connected to Type W internal street as a second access and installation of curb, gutter, five foot sidewalk on the north side, as well as pavement improvement shall be required. • 44th Ave S at North East side of the property is required to extend and connect to 30 –foot Tract X on south. However, if the wetland does not allow the road to extend and use the S 326th Pl at Military road as a primary access of the property then apply for modification request. 3. The applicant may make a written request to the Public Works Director to modify, defer, or waive the required street improvements (FWRC 19.135.070). Information about a right-of-way modification requests are available through the Public Works Development Services Division. These modification requests have a nominal review fee currently at $500.00. 4. Tapers and transitions beyond the project frontage may be required as deemed necessary for safety purposes, taper rate shall be WS^2/60 or as directed by the Public Works Director. Transportation Impact Analysis (TIA) (FWRC 19.135) 1. A Transportation Impact Analyses (TIA) to identify transportation impacts of development projects and provide appropriate mitigation measures is required. The TIA shall assess additional project impacts beyond those that were identified under the concurrency permit process conducted by the City. Mitigation improvements necessary beyond those identified in the TIP to meet the city’s adopted level-of-service standards shall be provided by the applicant. 2. A Traffic Impact Analysis (TIA) prepared by engineer licensed in the state of Washington is required for this development project if direct access from Military Rd to the project frontage is granted. . The engineer should contact the Traffic Division for a scoping sheet in the initial stages of their study. The TIA should include the following analysis:  Left-turn lane warrant analysis  Intersection Sight distance analysis per AASHTO Access Management (FWRC 19.135) 1. Access management standards are based on roadway safety and capacity requirements. FWRC 19.135.280 provides access standards for streets based on planned roadway cross-sections. Please note that access classifications are per Drawing 3-1A in the Public Works Development Standards. 2. Please show all neighboring driveways within 150 feet of the proposed driveway(s). 3. Military Rd S is Access Class “ 3”, which permits full access as close as 150 feet to any other street intersection or driveway (whether on or off the subject property) or aligned with those on the opposite side of the street. The current proposal may not meet required spacing standard with existing Private Street intersection, north of the property and proposed driveway and may need to be modified. Access may be further restricted if such access contribute to roadway collision. 4. Driveways that serve any use other than detached dwelling units may not be located closer than 150 feet to any street intersection or to any other driveway, whether on or off the subject property. Separation distances shall be measured from centerline to centerline of roadways and driveways 5. Driveways shall be aligned with driveways on the opposite side of the street 6. Driveways that serve only residential uses may not be located closer than 25 feet to any street intersection or driveway. Separation distances shall be measured from centerline to centerline of roadways and driveways 5. The director may grant a modification administratively to reduce spacing standards by up to 20 percent of the tabular values with supporting documentation (FWRC 19.135.290). Please note that these modification requests have a nominal review fee of $500. Once preliminary traffic queuing analysis has been completed, the applicant’s traffic engineer may submit a written request for access modification if desired. 6. Submit an intersection sight distance analysis for the design vehicle used at the plat access driveway/intersection with Military Rd. The analysis shall be conducted in accordance to the latest AASHTO guidelines (3.5 ft object height, 3.5 ft driver’s eye height, 14.5 ft back from the edge of the traveled way for passenger vehicles). The analysis must bear the seal of a licensed engineer in the state of Washington. The sight distance triangle shall be depicted on the plan set. 7. Please provide photo documentation within the appendix of the sight distance analysis. A minimum of one photo looking to the left and one looking to the right will show the location of the viewer in accordance to AASHTO guidelines. The Site Plan with plan and profile sheets should also be incorporated into the report to provide the site distance documentation. Indicate if there are any street trees, landscaping requirements, or any other objects existing or proposed to be within the sight distance triangle. State if the sight distance requirements are met or not and provide any traffic safety mitigation measures. . Design Criteria (FWRC 18.55) 1. No street, or combination of streets, shall function as a cul-de-sac longer than 600 feet (FWRC 18.55.010). 2. All lots shall be accessed by a public street right-of-way (FWRC 18.55.020). In certain cases, lots may be accessed by an ingress/egress and utilities easement or alley subject to the requirements established in the city of Federal Way public works development standards. Residential lots should not have access onto arterial streets. 3. The proposed development exceeds 25 lots or 250 daily traffic volume equivalents, as such a secondary second access should be provided.
