19-103221CITY OF ti. Federal Way July 25, 2019 Amalani LLC Barry Margalese 105 S Main Street Unit 230 Seattle, WA 98104 CITY HALL 33325 8th Avenue South Federal Way, WA 98003-6325 (253) 835-7000 www. cityoffederalway, com Jim Ferrell, Mayor RE: Permit #19-103221-00-SM; CREEgWOOD SUBDIVISION, 21st Ave SW, Federal Way Right -of -Way Modification Request Dear Mr. Margalese: This letter responds to your request to modify required right-of-way improvements for proposed `Road B' within the Creekwood Subdivision. Federal Way Revised Code (FWRC) Section 19-135.070, Modifications, Deferments and Waivers allows the Public Works Department to grant a request to modify, defer, or waive the required street improvements only after consideration of four specific reasons. The reason most applicable here is contained in Section 19-135.070 (2) Unusual topographic or physical conditions preclude the construction of the improvements as required. After evaluating the existing site conditions, review of FWRC provisions (Section 19.135.030 through 19.135.070), and direction provided by the City Council, the Public Works Department hereby conditionally approves a modification to the typical City standard street section as follows: `Road B' is classified as a Type "W" Local street. If built to full standard, it would include 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 applicant has proposed two areas in which this cross-section would be narrowed to reduce impact to the stream buffer and steep, erosive slopes. While staff is supportive of a reduced cross-section for the ravine crossing and the east leg of Road `B', expected traffic and pedestrian safety requires more improvements than the applicant has proposed. The approved cross sections are described below. 1. Approved Reduction of Road B for Stream Crossing Section S for a distance of approximately 150' The total cross-section shall be 24' paved roadway consisting of two 12-foot lanes, 0.5' curb and 5' sidewalk on both sides; additional 1.0' on south side to accommodate a chain link fence between the sidewalk and ravine for pedestrian protection; and additional 2' (+/-) to accommodate Jersey barrier on the south side between the curb and sidewalk for pedestrian/vehicle separation. This will be within a total right -.of --way width of no less than 38 feet. Actual right-of-way width will be determined when a design is approved for the ravine crossing, to assure that all required improvements are fully within public right-of-way. Planter \\CFWF[LEl Wppricatioos\CSDC\PROD\dots\save\158820_79392_18150656.DOC strip is eliminated on both sides. The utility strip may be located under sidewalk, however, street lights must be provided. Ramp locations for the intersection of Road B and 22nd Ave SW will be determined during engineering review. 2. Reduction of Road B between 22nd Ave SW and 21st Ave SW (Section Q The total cross-section shall be 28' paved roadway; 3.5' planter strip, and 3' utility strip on the south side; 0.5' curb and 5' sidewalk on both sides; all within a total right-of-way width of 45.5 feet. On the north side of the street, planter strip is eliminated and the utility strip may be placed under the sidewalk. The utility strip on the south side shall be 3'wide. Street lights must also be provided. Additional Requirements / Conditions of Approval This right-of-way modification is limited to the roadway sections discussed in this letter. The proposed Sierra Scape Wall will be further reviewed during SEPA, preliminary plat and engineering review. bA different method of crossing the ravine may be required. This right-of-way modification is approved only for this project, and is therefore contingent upon Hearing Examiner approval of the preliminary plat. The conditions of this right-of-way modification will be applicable for a period of one year from the date of this letter. If the project is not completed within the one-year time limit, this waiver will be void and a new request for modification must be submitted.

Staff Analysis Road B is classified as a Type W street, including a 28' paved roadway, 4' planter strips, 5' sidewalks, and 3' utility strips on both sides, all within a 52' right-of-way. The applicant proposes two narrowed roadway sections for this area. The portion of Federal Way Revised Code that best applies to this situation is 19.135.070 (2) Unusual topographic or physical conditions preclude the construction of the improvements as required. Steep and erosive slopes are prevalent throughout the middle portion of this site. Although grading and intrusion into the stream buffer will occur with this proposal, the ravine crossing and road have been located along the north side of the property where slopes are somewhat gentler to reduce the impact of these activities. This also places them next to existing back yards, which has generated concern from the existing neighborhood. 1. Proposed Retluction of Road B for Stream Crossin(= Section S The first proposed reduction is at the stream crossing , extending for a distance of approximately 150'. The applicant proposes a 20' paved roadway with 5' sidewalk on the north side and block wall with guard rail on the south side. Planter strip would be eliminated on both sides, and utilities would be placed under the sidewalks. A 43' right-of-way width is proposed in this area, which is proposed in order to create a smooth horizontal transition between right-of-way widths and capture all of the structural and storm water improvements necessary to complete the ravine crossing. Staff supports a reduced section for the ravine crossing. However, given the expected traffic using the ravine crossing, and the need for pedestrian safety, the proposed section is too narrow. A reduced ravine cross section is approved as follows: -24' wide paved roadway consisting of two 12' lanes - sidewalk on both sides, with chain link fence protection next to the ravine. The sidewalk on the north side must be standard five foot width. The sidewalk on the south side must have a total of six feet to provide a one -foot area at the back for the chain link fence. -Jersey barrier separating the sidewalk and roadway on the south side. -Planter strip eliminated on both sides. -the utility strip may be located under sidewalk. -Right-of-way width will be determined when a design is approved for the ravine crossing, to assure that all required improvements are fully within public right-of-way, - Ramp locations for the intersection of Road B and 22°d Ave SW will be determined during engineering review. -total cross-section shall be 24' paved travel way, 0.5' curb and 5' sidewalk on both sides; additional 1.0' to accommodate a chainlink fence on the south side, and additional 2' (+/-) to accommodate jersey barrier on the south side, all within a total right-of-way width of no less than 38 feet. Actual right-of-way width will be determined. 2. Reduction of Road B between 22°d Ave SW and 215t Ave SW Section C East of the stream crossing, the applicant proposes a full -width (28 feet) paved road width, with typical 4' planter strip and 5' sidewalk on the south side only. Utility strip is proposed to be reduced to two feet. On the north side, the applicant is proposing a landscape buffer between the back yards and Road B to help mitigate the impact that the new road will have on the existing homes. The applicant proposes to eliminate planter strip and sidewalk, asserting that the landscape buffer will not require access via sidewalk, and planter strip would be redundant next to the landscape strip. A three foot -utility strip is proposed on the north. Total right-of-way width would be 43 feet. Staff supports a reduced cross section in this area, however pedestrian safety and adequate space for utilities must be maintained. Therefore, the reduction is approved as follows: -eliminate planter strip on the north side of the street -5' wide sidewalk is required on both sides of the street. Utility strip may be placed under the sidewalk on the north side. The utility strip on the south side shall be 3'wide. -total cross-section shall be 28' paved travel way; 3.5' planter strip, and 3' utility strip on the south side; 0.5' curb and 5' sidewalk on both sides; all within a total right-of-way width of 45.5 feet. Requirements / Conditions of Approval This right-of-way modification only approves the roadway sections discussed. The proposed Sierra Scape Wall will be further reviewed during SEPA, preliminary plat, and engineering review. A different method of crossing the ravine may be required. This right-of-way modification is approved only for this project, and is therefore contingent upon Hearing Examiner approval of the preliminary plat.

Specifically, we are proposing the following two Right -of -Way Modifications: 1. To reduce the right-of-way width and improvements for a f385'-long section of proposed Road B where it impacts a critical area buffer, and _? 2. To reduce the right-of-way width and improvements for a (length) -long section of Road B where future homes will only be located on the south side of the roadway. The first modification proposes to reduce the right-of-way for this Type "W" Street Section from 52' to 43' (east of the 22°d Avenue SW intersection) and will eliminate all on -street parking, and the sidewalk on the south side of the roadway for a f150'-long section of this roadway. This reduction is being requested in order to minimize the impact on the critical area, while still providing adequate vehicular and pedestrian access to the cul-de-sac and 15 homes that are being served by this roadway. The second modification proposes to reduce the right-of-way for this Type "W" Street Section from 52' to 43' and will eliminate on -street parking and the sidewalk on the north side of the roadway for a f385'-long section of this roadway. This reduction is being requested in -order to provide a much larger landscape buffer for the adjacent homes to the north. The following details how this modification request meets the requirements of F.W.R.C. 19.135.070: 1. The first request meets the criteria outlined under (2) Unusual topographic or physical conditions preclude the construction of the improvements as required. The existing ravine being proposed for crossing has unusual topographic and physical conditions in that it is a result of human activity. This project is proposing to stabilize this ravine and stop the ongoing erosion that is threatening the homes to the north. Per the Pre -Application Conference Summary (datedll/14/13), it was indicated that "City staff would support a modification request by the applicant to further reduce the street -section over the ravine, within I50 feet of Road A ", in order to reduce the impact on the ravine crossing. June 14, 2019 EJ Walsh Page 2 The proposed 43' right-of-way of Road B would have two 10' drive lanes with vertical curb and a sidewalk on the north side in the vicinity of the ravine within the previously described 150 feet. 2. The second request is being made under (1) The improvement as required would not be, advantageous to the neighborhood or city as a whole. Where the proposed lots 1-5 abut Road B, we are proposing the same 43' right-of-way but the improvements would include two- 10' drive lanes, one- 8' parking strip with vertical curb a planter strip and sidewalk on the south side of the roadway. Improvements on the north side of Road B, beyond the vertical curb would include street trees and landscaping. The reduction in right-of-way width and improvements will provide a larger landscape buffer, which is advantageous to the existing neighborhood to the north. It will also minimize the impacts to these lots during construction, while giving the new development a secondary access to relieve pressure on the non -code compliant cul-de-sac length of 22nd Avenue SW. Per the information provided above the developer and project design team requests modifications from the ROW standards in -order to reduce buffer impacts. Thank you for your consideration and please do not hesitate to contact me if you have any questions or need additional information. Sincerely, CORE DESIGN, INC. Joshua P. Beard, P.L.A. Principal, Senior Project Landscape Architect Traffic iCopsuttantsjmc,. _ MEMORANDUM Barry Margolese Brad Lincoln, PE CreekWood Roadway Connectivity August 1, 2014 GTC #14-132 Gibson Traffic Consultants, Inc. (GTC) has been retained to address roadway connectivity within the CreekWood development. The CreekWood development proposed to consist of 25 units and is located west of 2l't Avenue SW and south of the terminus of 22"d Avenue SW. a site vicinity map is included in Figure 1. Figure 1: Site Vicinity Map Source: Google Earth The development is currently proposed to have internal connectivity between 21" Avenue SW and 22"d Avenue SW. A copy of the site plan is included in Figure 1. 2802 Wetmore Avenue - Suite 220 - Everett WA, 98201 Tel: 425-339-8266 - Fax: 425-258-2922 - E-mail: info@gibsontrafflc.com CreekWood Comment Response '�-� —•-- - _ _ ..a.eic ar ,.�e+s- ' j rimer - - Wl .;V Figure 2: Site Plan There are currently 98 single-family residential units that utilize SW 307'h Street as their single point of access. There are 34 of these units that utilize 22rid Avenue SW to access SW 307th Street and subsequently access 21' Avenue SW. The access to 21" Avenue SW and connection to the south terminus of 22nd Avenue SW will provide a second access to the existing 98 single-family residential units that currently use SW 307th Street as their single point of access. 1. Internal Connectivity The CreekWood development is proposing to have internal connectivity between a new access to 21 St Avenue SW and the existing south terminus of 22°d Avenue SW. This internal connectivity satisfies three sections of the City of Federal Way Public Works Development Standards (PWDS). Each of these sections is discussed below. 1.1. PWDS 1.3.2 Streets - A Section 1.3.2 Streets — A of the PWDS states that: "Streets will be designed and constructed in conformance with the provisions of...King County Road Standards (KCRS)..." Section 2.19 of KCRS states that: "No residential street shall serve more than 100 lots or dwelling units unless the street is connected in at least two locations with another street..." Gibson Traffic Consultants, Inc. August 2014 info@gibsontraffic.com 2 GTC #14-132 CreekWood Comment Response The addition of the CreekWood development will results in 117 units utilizing SW 307" Street if the internal connection is not provided since 19 of CreekWood units would utilize SW 307t" Street. The CreekWood internal connection will provide a second access to satisfy the requirements of KCRS 2.19. 1.2. PWDS 1.3.2 Streets — C 5. Section 1.3.2 Streets — C 5. Of the PWDS states that: "More than one connection to the existing public street system will be provided for any development... generating more than 250 trips per day or morel (25 single-family lots)" This requirement of PWDS is similar in nature to the section from the K-CRS.- The internal connectivity of the CreekWood development would provide a second access for-Ae existing 98 units and 117 total units that would be required to use SW 307t' Street without the internal' connection. 1.3. PWDS 3.2.11 Street Layout The first sentence of Section 3.2.11 Street Layout of the PWDS states that: "No street or combination of street shall function as a cul-de-sac longer than 600 feet" The existing total roadway length to the.uth terminus of 2211 Avenue SW is approximately 1,200 feet. This length is nearly twice the length of the PWDS requirement. The internal connection of the CreekWood development will provide a second connection will eliminate 22"d Avenue SW as a cul- de-sac and satisfy the requirements of PWMS 3.2.11. 2. Conclusion The CreekWood development is proposing to provide an internal connection that will provide connectivity between the existing south terminus of 22" d Avenue SW and 21' Avenue SW to satisfy three sections of the City of Federal Way Pyblic Works Development Standards (PWDS). The internal connection will provide a second access to the existing 98 units and 17 additional units that would be required to use SW 307`h Street if the internal connection is not made. GTC therefore recommends that the internal connection be made to enhance the connectivity and safety of the roadways in the site vicinity and satisfy the required of PWDS.
