You requested variances from Sections 2.10 and 2.08 of the KCRS concerning the intersection spacing and cul-de-sac design for the proposed new access onto I 16th Avenue SE. The KCRS requires 500 feet of intersection spacing along a minor arterial. A hammerhead turnaround is proposed at the intersection in the plat interior. ·~e reviewed your proposal and agree tha~et of intersection spacing to the south t SE 184th Street would be acceptable. The-proposed range of intersection spacing would allo the proposed access point or an access located near or at the north property line. The Deprtrtment of Development and Environmental Services' (DDES) Subdivision Technical Corrunittee will be determining the exact intersection location. A minimum of 350 feet of intersection spacing would be provided to the north to SE 182nd Street. I approve a variance for the proposed range of minimum intersection spacing from 268 to 300 feet to the south to SE 184th Street and the resultant reduced intersection spacing to the north to SE 184th Street. The proposal for a hammerhead turnaround is denied. There is a sufficient flat useable area within the site to provide a standard 80-foot diameter turnaround bulb. The DDES will be determining if a temporary bulb can be provided. This decision applies only to KCRS identified in the variance request. All other design requirements in the KCRS and other regulations, such as surface water management and zoning, must still be satisfied for a land use permit application. The applicant retains the rights and privileges afforded by King County Code and adopted Public Rules pertaining to road variance processing (KCC 14.42, PUT I 0-2). This variance decision is valid for one year from date of letter unless an associated land use permit is pending or submitted within the one year period. In these cases, the variance decision is valid for the duration of the permit processing. @·~12021,1 Jim lfildebrand June 20, 2006 Page 2 A copy of staff's analysis, fmdmgs, ana: conclusfons is enclosea.

The proposed seven-lot short plat is at 18311 -I 16th Avenue SE. A new intersection onto I 16th A venue SE is proposed for the access road into the site. The street at I 16th A venue SE is classified as a minor arterial for which the King County Road Standards (KCRS) requires a minimum of 500 feet of intersection spacing. The existing spacing between SE 182nd Street and SE 184th Street at 650 feet make compliance with the required 500 feet of intersection spacing impossible. There are no alternative accesses to the site other than off I 16th Avenue SE. The applicant proposes a minimum of268 feet of intersection spacing to the south to SE 184th Street. This would leave over 350 feet of intersection spacing northward to SE 182nd Street. 2. A variance is also requested for a hammerhead turnaround for the interior access road. A King County Alternative Fire Apparatus Access Turnaround "hammerhead" would result in a more confonning lot layout as well as storm drainage and recreational tracts. The hammerhead would be at an intersection that provides stubs to the north and south. This will help eliminate additional non-conforming access points to I 16th Avenue SE. Staff's Findings and Conclusions: I. The proposed layout on the plans with the access 57 feet south of the north property line would result in a 268 foot intersection spacing to the south to SE 184th Street. Over 350 feet of intersection spacing would result to the north to SE 182nd Street. The subdivision technical committee requested intersection spacing variance approval to allow an alternative access near the north property line. The committee is still deliberating on the exact location for the access. The entering sight distance at the proposed access far exceeds KCRS minimums. 2. There is no good reason that a standard cul-de-sac bulb (80 feet in diameter) cannot be provided on the site. The Department of Development and Environmental Services (DDES) will determine if a temporary turnaround (80 foot in diameter) would be allowed. y arian,:e File June 20, 2006 Page2 -----3. The roam, oiilneplans have a private road label. The plans show the stub road to-the south not extending to near the property line. Consultations with the DDES clarify that the interior roads will be dedicated to King County (public) and tl\atlh_e, stub to the south would be extended to nw-the property line. -----.. --. .

Grading and Clearing Permit review and inspection fees are calculated using both base fees and hourly fees. The total cost of a permit will vary depending upon the complexity of the project and the number of ancillary reviews that are required to complete the application review (e.g., drainage, SEPA, or critical area review). Base review and inspection fees are estimated using target hours. Target hours are intended to provide staff and the applicant a very general estimate of the time to complete certain standard reviews. Target hours for inspection functions represent minimum inspection levels. If target hours are exceeded, additional reviews and inspections will be billed at the department's current hourly rate**. Certain reviews, such as drainage and SEPA review, are billed at the current hourly rate for each hour of review time. DOES collects a deposit at the time of application submittal up to 50% of the anticipated hourly charges for the project. Direct hourly charges in excess of deposit amounts, or charges in excess of base fees, will be billed to you monthly. Finance charges will accrue if invoices are not paid in a timely manner. In addition to the standard review and inspection fees applicable to all permit applications, certain other fees and base fee adjustments may be applicable to clearing and grading projects. These include, but are not limited to: • Counter Service Fees -Intake fees will be assessed for all permit applications except miscellaneous clearing permits, which are assessed hourly charges. Issuance fees will be assessed for all clearing and grading applications, except short form permits. • Investigation fees -Investigation fees are assessed any time work proceeds prior to issuance of a permit. Investigation fees are equal to the amount of the base review fee. Fees paid for pre-application review to resolve an active code enforcement case may be applied toward the required investigation fee. Other review fees may be assessed during the course of project review if the project or scope of the project is particularly complex. DOES makes every effort to notify customers when these additional reviews are required. In some cases, projects can be modified to avoid additional reviews. I have read the foregoing and understand that the estimated fees contained on this worksheet are only an estimate and the actual cost of this permit will depend upon the review services required and the complexity of the proposed project. I accept financial responsibility for all fees associated with this permit or approval. -DOES fees are based on the latest fee ordinance adopted by the King County Council and are subject to change. As of June 1, 2007, the DDES standard hourly rate is $140/hour. '!';.. '--~~A~~!1/ &> 7~ It .

As determined necessary by King County, the permit applicant for each lot must prepare a drainage site plan with procedures for design and maintenance details, and record a declaration of covenant and grant of easement for implementation of the best management practices." (B) Flow control credits are used for sizing the drainage facility and the plat developer will implement the required BMP's as part of the subdivision process. This will occur only for certain types ofBMP's such as full dispersion to an open space tract, full infiltration for entire plat, or construction of a joint use rain garden located within a separate tract. The feasibility ofBMP's has been determined with design details shown on the plans including roof drain connections. In this case, the final plat must record a note indicating that BMP requirements are satisfied and building permit review is not required.
