17-106107June 26, 2018 Mr. Marwan Salloum Public Works Director City of Federal Way 33325 81h Avenue S Federal Way, WA 98003 RE: Permit #17-106107-00-SM Response Follow Up Pena Short Plat Subdivision, Phase II Dear Mr. Salloum: Job No.1971-001-017 RESUBMITTED JUN292918 C0zORY OF FEOEF{AL WAY UNfTY DEVELOpMEhT Thank you for responding to the latest right-of-way modifications request for the Pena Short Plat (#17-106104-00-SU). Since your response on April 131h, 2018, ESM met with City of Federal Way staff to discuss our findings and concerns with this dedication. Upon review and considerations of more correspondence with the City of Federal Way and WSDOT (the adjacent property owner), we believe that a greater 'reduction of ROW dedication will accommodate the goals of the City of Federal Way and provide access within the local community while complying with the FWRC regarding your Authority to Require Dedication. In addition to the justification we've previously submitted to the City for review, please see below for ESM's response to your conditions and/or reasons for denying the additional right- of-way dedication reduction requested for the Pena Short Plat, Phase II. Authority to Require Dedication -- FWRC 19-135.040(4) In your response on February 21, 2018, you stated that this project is not eligible for the exceptions listed in this section because it does not fit one of the two qualifying criteria. However, based on discussion with WSDOT and with the City of Federal Way, it is clear that the property adjacent to this project is anticipated to be developed in the near future. In our discussion with WSDOTs Real Estate department, we learned they are currently preparing to sell the property to a developer. Additionally, in our meeting with City staff on June 8, 2018, EJ Welsh informed us that the City of Federal Way has regularly been in correspondence with WSDOT regarding the development of this specific property. 33400 8th Ave S Ste 205 Tel (253) 638 6113 Everett (425) 297 9900 Civil Engineering Land Planning Federal Way, WA 98003 Fax (253) 838 7104 Toll Free (800) 345 5694 Land Surveying Landscape Architecture www esmcivil corn 3D Laser Scanning GIS Mr. Marwan Salloum June 29, 2018 Page 2 Therefore, the Pena Short Plat, Phase II proposal does qualify to be subject to FWRC 19.135.040(4), where the City may require up to 300 square feet of right-of-way dedication per average daily trip generated by the development, or up 20,100 SF. After meeting the ROW dedication requirement for SW 34411, Place, 8,642 SF remained to be required for dedication, which equates to slightly less than a 13' width along the entire northern portion of the property. This project originally proposed to only dedicate 13' of right-of-way along the SW 344th Street extension. Upon reviewing the City's concerns for alignment and plans to connect the right- of-way, we then proposed 28' of ROW dedication, which is about twice the amount that is req u i red per the FWRC 19.135.040(4)(b). ESM also prepared an exhibit to reflect how this alignment could work utilizing the proposed 28' dedication, along with the existing 50' public access and utility easement on the WSDOT property, resulting in a full, 78'-wide right-of-way. City staff had recommended that we update the proposed alignment exhibit for SW 344th Street to depict how the street could be designed in a manner that reflects the current public works standards, and it is enclosed for your review. We believe that by maintaining the proposed 28' right-of-way dedication from the Pena property (with corner radii along SW 344th Street), City's goals and the surrounding community residents are attainable. Please see the updated proposed SW 344th Street alignment exhibit enclosed with this letter. WSDOT Access Easement and/or ROW Dedication The more recent response we've received from the City of Federal Way regarding the proposed right-of-way dedication indicated that the project will need to "obtain a public right-of-way dedication of 50 feet in order to proceed with [the] request" At our meeting with the City of Federal Way, we learned that WSDOT and the City have been in correspondence for years regarding the sale and development of the remaining property adjacent to the Pena property. Additionally, City staff informed us that while the 50' access easement was recorded, it was intended to be dedicated to the City when the Park and Ride was developed but it was never deeded to the City. Thus, the 50' access easement has since been meant to be included in the SW 344th Street right-of-way and will be dedicated with a future development approval of this adjacent property. Frontage Improvements The Public Works Director previously granted a waiver of all frontage improvements on SW 344th Street for this project. Due to this project's proposed dedication and uncertain development timeline, we believe that maintaining this waiver is appropriate. Mr. Marwan Salloum June 29, 2018 Page 3 Thank you for time and attention to this request, considering this proposal, the neighboring future development and proportionality for each project. We look forward to working with you through the Citys review and approval process. Should you have any questions, or require additional information, please contact me directly at 253- 838-6113.

This is a reduction from the decision dated 2/21/18 which required 39 feet to be dedicated. The new request requires the majority of the improvements to be located on the property to the north, where there is an existing 50' wide access and utility easement originally provided to King County. Since the City of Federal Way requires right-of-way to be dedicated rather than placed in an easement, the applicant will need to obtain a public right-of-way dedication of 50 feet in order to proceed with this request. Otherwise, if and when the property to the north is developed, the City would typically require a half - width right-of-way dedication of 39 feet.

Upon review of your response and further research into the project site and surrounding properties, we believe that a greater reduction of ROW dedication will still accommodate the goals of the City of Federal Way and provide access within the local community. Specifically, we do not believe that your deviation approval considered the existing 50-foot wide public access and utility on the adjacent property to the north, as this was not included in our earlier submittal. With this new information, we are proposing a 28-foot wide right-of- way dedication along the northern portion of the site. The following additional information is provided for your consideration: The King County Department of Transportation (KCDOT) property to the north of the site is partially developed; however, the eastern portion of the site adjacent to the Pena property is undeveloped. The eastern portion of the KCDOT property contained a wetland at the time the project was built (1996/1997). According to the wetland consultant hired by the Pena's, and confirmed by one of WSDOTs biologist, this wetland no longer exists; therefore, there is a high potential for this site to be developed in the future. a At the time the KCDOT project was constructed, the westerly extension of SW 344th Street was not constructed due to the perceived lack of usage. Please see the enclosed Hearing Examiner Review from 1996, specifically page 3-4, for further information.

Please see the enclosed sketch for a conceptual alignment and design. ESM has recently been contacted by a developer seeking to acquire the properties that would make up the majority of this alignment. This includes the prior Saghalie Heights plat (KC parcels 192104-9019 and 192104-9018) and the eastern portion of the KCDOT property (parcel 242103-9008).

Permit #17-106107 00-SM; PENA SHORT PLAT, PHASE H, Y00ff SW 344TH ST, Federal Way Dear Ms. Nagorski: CITY HALL 33325 8th Avenue South Federal Way, WA 98003-6325 (253) 835-7000 www. cityoffederalway. com Jim Ferrell, Mayor This letter responds to your request to modify required right-of-way width and improvements for SW 344th Street, which is located on the north side of the property and is designated by the Comprehensive Plan as a Type "K" street . To meet requirements for this project, and to follow the established alignment to the west, the City requires a fifty -foot wide right-of-way dedication and minimum frontage improvements of twenty-two feet of pavement, six-foot planter strip, eight -foot sidewalk, and three-foot utility strip along the property frontage. Federal Way Revised Code (FWRC) Section 19-135.070, Modifications, Deferments and Waivers allows the Public Works Director to grant a request to modify, defer, or waive the required street improvements only after consideration of specific reasons. The reason most applicable to the reduced dedication is contained in Section 19-135.040(4) (b) Authority to Require Dedication. The dedication required for this short plat exceeds the rough proportionality threshold of 300 square feet per average daily trip described in this code section. However, to qualify for this reduction one of two criteria must be met: (a) "It is likely to anticipate that, within the near future, the private property across the right-of-way will be required to dedicate property for public right-of-way; or (b) The reduction in the required right-of-way width will nonetheless provide adequate room for all improvements...." In this case, criteria (a) is not met since the property across the street is developed and has no current plans to redevelop. Criteria (b) is not met by the applicant's proposal to dedicate thirteen feet. However, the improvements can be constructed within a dedication of thirty-nine feet; therefore the Public Works Director hereby grants a reduced right-of-way dedication of thirty-nine feet. FWRC Section 19-135.070 (3) "Proper vertical or horizontal alignments cannot be determined because the existing streets do not have correct alignments" applies to the frontage improvements required on SW 344th Street. In addition, the applicant will construct frontage improvements along SW 344th Place, where all of the lots will gain access to public streets. In light of this and the alignment issues on SW 344th Street, the Public Works Director hereby grants a waiver of all frontage improvements on SW 344th Street. \\CFWFILEI\Applications\CSDC\PROD\docs\save\149472_77317 20135558-DOC Additional Requirements / Conditions of Approval Conditions of approval are as follows: • Prior to recording the short plat, frontage improvements on SW 344ffi Place shall be completed. • The short plat map shall include a statement that all access must be obtained off of SW 344th Place. A thirty-nine foot right-of-way dedication along the property's north property line shall be recorded via statutory warranty deed and shown on the short plat map. 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.

The infiltration rate of 10.9 min./in. was used, which is the same as in the original pond sizing. However, please be aware that actual measured infiltration rate plus a factor of safety of 2 is equal to 5.5 min.fin. according to the original T.I.R. The peak flows were regenerated based on the information in the original T.I.R., however the King County program was used instead of Waterworks. The control riser as designed uld not be installed due to conflict in design elevations. In iieu of the riser, an overflow pipe was in tailed_ Our calculations show that the 100-yr water surface using as -built information is at elevation 3 14, which is lower than the design elevation of 350.56. The lowest elevation along the pond be is at 351.20 at one location, therefore, a 1-f0ot freeboard is still available. We believe the detention pain will function as designed and has adequate capacity to handle the 100-yr storm.

The subject property includes 2.53 acres (110,335 square feet) to be subdivided into seven (7) single-family lots. The proposed access is along SW 344th Place, similarly to the Pena Short Plat Subdivision, Phase I that is directly west of the proposed site. Please see the included Sheet 3 for reference. Comments provided by the City in the pre -application summary letter stated that the applicant would be required to dedicate 50-feet of right-of-way (ROW) width from the northern portion of the subject property. This is due to an element of the Comprehensive Plan that depicts a 3-1ane east -west principal collector road extending from 18th Avenue SE to 15th Place SW, to accommodate a Type "K' street with a 78-foot right-of-way (ROW). The adjacent property to the north is currently undeveloped along this proposed ROW. We are proposing a 13-foot wide right-of-way dedication along the northern portion of the site due to the following justifications: This project proposes a 22-foot dedication of the southern portion of the property for right-of-way and street frontage improvements .along SW 344th Place that equates to 11,458 square feet.

For the purpose of determining the rough proportionality of right-of-way dedication to the developments impact, the City may require up to 300 square feet of right-of-way dedication per average daily trip generated by the development" o Per the Institute of Transportation Engineers (ITE) Trip Generation - gth Edition, land use code 210 (Single Family Detached Housing), the proposed project is estimated to generate approximately 67 average daily trips. o This equates to a maximum area that the City may require for right-of-way dedication of the property of 20,100 square feet. o After the 22-foot dedication from the southern portion of the subject property is deducted, this leaves 8,642 square feet from the northern portion. The proposal for 13' wide dedication along the length of the property equates to 8,666 square feet, exceeding the area the City may require for dedication. ■ Though we are unaware of the development plans for the northern adjacent property owner, King Transit, we anticipate within the near future that they will be required to dedicate property for the remaining public right-of-way needed [FWRC 19.135.040(4)(a)]. Additionally, we are requesting a complete waiver for improvements along the SW 344th Street right-of-way to be dedicated to the City due to the following justifications: FWRC 19.135.070 states that the public works director, "...may modify, defer or waive the requirements of [chapter 19 if ...] (1) The improvement as required would not be harmonious with existing street improvements, would not function properly or safely or would not be advantageous to the neighborhood or city as a whole." o It is our understanding that a minimum of 20-feet of pavement is required along any public roadway. As the ROW will be limited to 13, making these improvements is not feasible for this project. o Any improvements along this ROW would not provide benefit to the proposed single-family home development, as sufficient access already exists. FWRC 19.135.070(3) states, "Proper vertical or horizontal alignment cannot be determined because the existing streets do not have correct alignments" as a reason for a waiver of requirements. o The ROW to be dedicated from this proposal, along with the City's proposal to add lanes into the existing adjacent street -section, does not provide a clear or correct alignment for connection to the existing SW 344th Street.

The applicant would be expected to dedicate right-of-way and construct improvements for the portion of the road extension abutting and within the subject property. This road is designated as a Type "K" street, consisting of a 44-foot street with curb and gutter, six-foot planter strips with street trees, eight -foot sidewalks and street lights in a 78-foot right-of- way (ROW). Following the established right-of-way line to the west, 50' ROW dedication and half -street improvements as measured from street centerline is required. The applicant is requesting a reduction of the 50' right-of-way dedication and proposing a 13- foot wide dedication instead. The applicant is also requesting the frontage improvements on SW 344`h Street be waived. The applicant will be dedicating 22 feet of right-of-way and constructing frontage improvements on SW 344 h Place, where access for the new lots is proposed. The applicant states that a 13-foot wide dedication on SW 344t' Street will provide adequate room for all improvements and is justified based on FWRC 19.135.040(4)(b) Authority to Require Dedication. The combined dedication of 11,458 square feet on SW 344`h Place and 8,666 square feet on SW 344`h Street meets and slightly exceeds the rough proportionality threshold described in this code section. However, criteria (a) "It is likely to anticipate that, within the near future, the private property across the right-of-way will be required to dedicate property for public right-of-way " is not met, since that property is fully developed and no changes have been proposed. Criteria (b) "The reduction in the required right-of-way width will nonetheless provide adequate room for all improvements... " is also not met. The applicant has not shown, and actually contradicts her claim, that adequate improvements can be achieved within the 13' wide dedication when she later claims that the improvements are infeasible per FWRC 19.135.070 due to lack of right-of-way. Since the criteria for reduction are not met, staff does not recommend approval of the 13-foot right-of-way dedication. However, reducing the dedication to the standard half -width dedication of 39 feet is recommended since frontage improvements can be accomplished within that width. Staff further recommends waiver of the frontage improvements on SW 34e Street with conditions, since frontage improvements will be provided along the street that is providing direct access to the lots. Requirements / Conditions of Approval 1) Prior to recording the short plat, frontage improvements must be completed on SW 344t' Place 2) No individual lot ,ess may be taken off of SW 344" Stre, - This condition shall be shown on the short plat drawing. 3) Right -of -Way dedication of 39 feet in width must be provided along the property's north property line for SW 344t' Street. A statutory warranty deed is required.

The subject property includes 2.53 acres (110,335 square feet) to be subdivided into seven (7) single-family lots. The proposed access is along SW 344th Place, similarly to the Pena Short Plat Subdivision, Phase I that is directly west of the proposed site. Please see the included Sheet 3 for reference.

We are proposing a 13-foot wide rs ht of-wa dedi along the northern portion of the site due to the following justifications: This project proposes a 22-foot dedication of the southern portion of the property for right-of-way and street frontage improvements along SW 344th Place that equates to 11,458 square feet.

For the purpose of determining the rough proportionality of right-of-way dedication to the development's impact, the City may require up to 300 square feet of right of -way dedication per average daily trip generated by the development" o Per the Institute of Transportation Engineers (ITE) Trip Generation - 8rh Edition, land use code 210 (Single Family Detached Housing), the proposed project is estimated to generate approximately 67 average daily trips. o This equates to a maximum area that the City may require for right-of-way dedication of the property of 20,100 square feet. o After the 22-foot dedication from the southern portion of the subject property is deducted, this leaves 8,642 square feet from the northern portion. The proposal for 13' wide dedication along the length of the property equates to 8,666 square feet, exceeding the area the City may require for dedication. • Though we are unaware of the development plans for the northern adjacent property owner, King Transit, we anticipate within the near future that they will be required to dedicate property for the remaining public right-of-way needed [FWRC 19.135.040(4)(a)].
