P.Q. Box 2401 Kirkland, WA 98116 RE: Road Variance L05VO066 —Talbot Ridae Estates — Related File L05P0007 Dear Mr. Williams: Thank you for your application for variances from the King County Road Standards (KCRS). You requested variances from Sections 2.12 and 2.13 of the KCRS concerning the entering sight distance (ESD) onto, and the stopping sight distance (SSD) along SE 192nd Street. A crest vertical curve at the intersection with 102nd Avenue SE limits sightlines. We reviewed your proposal to reconstruct the vertical alignment of SE 192nd Street to improve the SSD to meet the American Association of State Highway and Transportation Officials' (AASHTO) minimums. A minimum 280 feet of SSD should be provided utilizing a two -foot target. This would require up to five feet of fill on SE 192nd Street, west of the intersection with 102nd Avenue SE. I approve a variance to utilize AASHTO standards for the SSD with the following conditions: 1. The applicant must adjust the driveway approaches to the realigned SE 192nd Street. Letters have been provided permitting the driveway adjustments on the private properties. 2. Clearing must be performed within the right-of-way (ROW) of SE 192nd Street to maximize the ESD for the driveways along the reconstructed road. The proposed 415 feet of ESD to the left (west) on 102nd Avenue SE, exceeds the minimum AASHTO criteria of 390 feet for the 10 over posted design speed of 35 mph. Actual approach speeds from the west are reduced by the curvilinear horizontal alignment as evidenced by the measured 32.2 mph 85th percentile eastbound speed on SE 192nd Street. I approve a variance for reduced ESD to the left (west) with the condition that clearing be performed in the ROW to provide a minimum 415 feet.. The available ESD to the right exceeds the KCRS minimum of 490 feet. The Department of Development and Environmental Services (DDES) will be determining the cross section for the reconstructed road and reviewing the engineering submittal for compliance with the KCRS. The requested variance for the proposed six percent. horizontal curve superelevation on SE 192nd Street was not necessary. Your proposal appears to meet & -< ,M2- Cliff Williams, P.E. September 21, 2006 Page 2 superelevation criteria in Table 2.2 of the KCRS if a three percent superelevation is provided for the 360-foot horizontal curve radius. The design details should be coordinated with the reviewing agency, the DDES. This decision applies only to King County Road Standards 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 10-2). 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. A copy of staffs analysis, findings, and conclusions is enclosed. If you have any questions, please call Craig Comfort, Road Variance Engineer, Traffic Engineering Section, at 206-263-6109. Sincerely, Paulette Norman, P.E.

The Talbot Ridge Estates preliminary plat has 27 lots and fronts SE 192nd Street and 102nd Avenue SE. Variances are requested for reduced entering sight distance (ESD) looking to the left (west) from 102nd Avenue SE onto SE 192nd Street, and for reduced stopping sight distance (SSD) along SE 192nd Street for the 250 feet of urban frontage improvements. A crest curve along SE 192nd Street at 102nd Avenue S. limits sight lines. The King County Road Standards (KCRS) minimum ESD for the 10 over posted design speed of 35 mph is 620 feet, and the minimum SSD is 250 feet. 2. The measured ESD to the left (west) from 102nd Avenue SE is 340 feet. Sightlines are restricted by trees along the north edge of the right-of-way (ROW) at the inside of a horizontal curve. With clearing in the ROW, ESD can be improved to 415 feet. With the trees removed, fencing and structures along property lines would restrict the sightline. The ESD deficiency is mitigated by speed reductions along the curvilinear road alignment and upgrade in the SE 192nd Street approach to the intersection. West of the site are cautionary 15 mph warning signs in both directions of travel. A speed study determined that the 85th percentile approach speed of eastbound vehicles is 32.2 mph. Accident report data for the last four years showed only one accident at the SE 192nd Street intersection. The ESD does not appear to be a factor in that accident. 3. The SSD over the crest vertical curve to the east of the intersection with 102nd Avenue SE does not meet KCRS. The applicant proposed two alternative designs, one meeting KCRS based upon a six-inch target and one meeting the American Association of State Highway and Transportation Officials' (AASHTO) manual SSD criteria with a two -foot target. A minimum of 317 feet of downgrade adjusted SSD would be provided. The profile based upon the six-inch target would result in reconstruction of 1,100 feet of SE 192nd Street with fill sections to four feet deep. The profile meeting the AASHTO two -foot target would result in reconstructing 700 feet of SE 192nd Street with fills to five feet in depth. Note that both alternatives propose filling on both sides of the crest curve because the road cannot be lowered due to utility conflicts and the intersection approaches on 102nd Avenue SE. The applicant requests a variance to use the two -foot target profile because of Variance File September 21, 2006 Page 2 extensive construction for the six-inch target profile. Letters have been provided from homeowners along the adjusted roadway that will allow for driveway adjustments for the realigned vertical profile. The applicant provided an analysis showing that the ESD and SSD for the driveways along the road reconstruction are either improved or equivalent to the existing conditions. Staffs Findings and Conclusions: 1. Clearing should be performed in right-of-way (ROW) to the extent possible to enhance the ESD. The minimum AASHTO ESD for the 35 mph design speed is 390. Clearing will provide over 400 feet of ESD. 2. The design of the southeast quadrant of the intersection of 102nd Avenue SE and SE 192nd Street will be reviewed by the Department of Development and Environmental Services. The minimum curb return radius and transition paving tapers must be evaluated. 3. The proposed SSD variance with a minimum of 317 feet of SSD is more than the downgrade adjusted AASHTO value of 280 feet (Exhibit 3-2) for a 35 mph design speed. The two -foot target alternative for the revised vertical profile would result in fewer problems with driveway adjustments and result in a lower construction time period. 4. The Department of Transportation's Traffic Engineering Section files shows two accidents at the intersection in the past five years. In addition, two accidents were within 180 feet of the intersection. The proposal to improve the SSD should improve the safety along the road. 5. A variance was also requested on resubmittal for a non-standard superelevation design. This variance request was not necessary because a superelevation design per Table 2.2 of the KCRS can be provided. 0 King County Department of Development and Environmental Services Land Use Services Division 900 Oakesdale Avenue Southwest Renton, Washington 98055-1219 206-296-6600 TTY 206-296-7217 Road Standards Variance Request to the County Road Engineer Alternative formats available upon request Project Name: DDES File No. 00 Project Address and Parcel Number Si lu A Date: Applicant/Design Engineer Name: Engineering Firm Name: 41Z16 / rrQfG.i Address: 0 D, a I Telephone: fit` 7!� 714a / City, State Zip,:: DDES Engineer Initials: / /�f, ///&� ❑ Route Application to LUIS ❑ Check here if ! ect engineering lans are approved and construction has begun.

Box 2401 Kirkland, WA 98083-2401 Re: Talbot Ridge Estates Preliminary Plat King County Road Variance File No. L05VO066 Dear Mr. Williams: At your request, we have prepared this response to the letter dated September 23, 2005 from Peter Dye, P.E. of the King County Department of Development and Environmental Services regarding the above -reference sight distance variance request. The following responses are labeled per the four review comment paragraphs in that letter. A copy of Mr. Dye's letter is attached. a. The results of a traffic speed study of eastbound vehicles on S.E. 192Id St. are attached. The study was conducted by Traffic Count Consultants, Inc. using a traffic count machine and road tubes placed on S.E. 192nd St. at a location 300 feet west of the 102nd Ave. S.E. intersection. The data was recorded for three days, from Monday, October 3, 2005 through Wednesday, October 5, 2005. The eastbound 85% speeds for the three days were 32.0 MPH, 32.5 MPH and 32.1 MPH, respectively. The data included all of the eastbound vehicles, which were more than 2,300 vehicles each day. Westbound speeds and traffic volumes were also recorded, but this information was not requested and for simplicity is not included herein. b. Urban frontage improvements to the site frontage on S.E. 192nd St. are proposed for this project, as shown on the attached Sight Distance Exhibit prepared by CORE Design. C. The attached Sight Distance Exhibit shows proposed curb, gutter, sidewalk and pavement widening improvements to the site frontage on S.E. 192nd Street. The proposed front face of curb is shown at 18 feet from the S.E. 192"d St. right-of- way centerline. The curb return at the intersection comer is shown at a 35 foot radius. The Sight Distance Exhibit also shows a plan view of stopping sight distance (SSD) lines and entering sight distance (ESD) lines for the intersection based upon County design requirements. The existing ESD line on the plan view indicates approximately 370 feet of ESD to the east of the intersection, limited by the existing trees within the right -of way on the north side of the road. The potential ESD line on the plan view indicates approximately 415 feet of ESD K04M205ESOvariance2.d6c Mirai Associates, Inc. 0 11410 NE 122nd Way, Suite 320 • Kirkland, WA 98034-6927 0 425.820.0100 - t • 425.821.1750 - f Transportation Pienning &.

November 18, 2005 Page 2 to the east of the intersection if the trees are removed, in which case the ESD would then be limited by the existing private fences located near the right-of-way line. d. The attached Sight Distance Exhibit also shows profile views of S.E. 192"d St. and the SSD lines and ESD lines to the west of the 102"d Ave. S.E. intersection. The SSD lines are shown for both the County standard six inch high object and the current AASHTO standard two foot high object. The County's letter also requested an evaluation of the road profile for compliance with standards in relation to the construction of urban frontage improvements on the vertical curve. In our review of the King County Road Standards, we found no design standards for crest vertical curves. The AASHTO "Green Book" notes that minimum lengths of crest vertical curves are based on sight distance criteria. It appears that approval of the variance requested for the existing sight distances would also imply acceptance of the existing crest vertical curve on S.E. 192"d Street. SSD and ESD were discussed in detail in our previous Entering Sight Distance Variance Request letter dated August 11, 2005. However, the field measurements of ESD discussed in that letter were taken from a point on 102nd Ave. S.E. ten feet south of the existing edge of traveled way on S.E. 192"d St. (prior to any widening). As shown on the attached Sight Distance Exhibit, the ESD is taken from a point on 102"d Ave. S.E. ten feet south of the extension of the proposed curb line. Since this point on 102nd Ave. S.E. is further south, the ESD's indicated on the attached Sight Distance Exhibit are greater than the ESD's identified in our previous letter.

Box 2401 Kirkland, WA 98083-2401 RE: Road Variance File No: L05VO066 Project: Talbot Ridge Eames Dear Mr. Williams: A road variance application regarding sight distance far the Talbot Ridge Estates subdivision was received by our office on August 25,'2005. Based upon preliminary review oFthe-desi isstus, additional infmmation is required befoie final processing of variance application. Iri order to continue our review, please address the following information and submit three copies each of any required design drawings or technical analysis. a. To evaluate the sight distance requirements for SE l Vd Street, please submit a traffic speed study prepared by a qualified traffic engineer. The study shall determined the SP percentile speed for vehicles traveling east bound on SE 192" Street at a location whero vehicles come into view from the intersection. This study must include a sample size of at least 100 eastbound vehicles. b. gased upon requirements outlined in Kitng.County Road Stsndards (KCRS)1.03B, King County requires urban frontage improvements for the proposed subdivision; however, the site pleas submitted with the variance application do not show the required road improvements along SE 1 J2' d Street. If frontage improvements am not proposed for any portion of the subdivision, this design issue must also be included in your variance application. c. To evahiate the urban frontage improvements and intersection de, please provide a design plan showing the curb radius and pavemern widening for SE 192 StrM. A plan view snowing sight distance measurements shall also be prepared for the intersection to evaluate sight line locations in relation to vehicle locations, limits of right -of way, and the removal of vegetation noted in the variance summary. The sight lines must be evaluated based upon the object locations and other design requirements outlined in MRS 2.12 and 2.13. _ ---- - r SEP 26 2005 1 I Cliff Williams September 23, 2005 Page 2 c. As noted in the summary provided with your variance submittal, a crest curve on SE 192d Street limits the stopping sight distance on SE lVdd Street. Your application indicates that King County standards for stopping sight distance are satisfied based upon AASHTO standards; however, King County does not recognize the AAS HTO standards unless approved through the variance application. To provide further evaluation of stopping sight distance, please provide a road profile of SE 192d Street with sight line measurements showing the sight distances and height of objects being used for the measurements. The road profile must also be evaluated for compliance with standards as related to construction of urban frontage improvement$ along SE 192" a Street. All required urban road improvements must be located on vertical and horizontal curves meeting County standards unless otherwise approved by the variance. The Land Use Services Division will hold your application in abeyance pending receipt of the above information. The deadline for submitting the required mfortnation is November 23, 2005.

Also attached are signed letters from the two property owners showing their willingness to allow regrading of their driveways. For your reference, we have enclosed a copy of the preliminary plan and profile submitted earlier. Regarding the need for a taper on the SE side of the 102"d Ave SE intersection, a short plat application is under review for the property fronting this leg of SE 192"d Street (L06SO016). I notified the DDES project planner, Karen Scharer of our project and requested the required frontage improvements be coordinated with the road improvements required for our project. This development may address the taper requirements. We understand this additional information addresses all remaining concerns. Therefore, we look forward to receiving the Road Variance approval shortly allowing the project to proceed to a hearing. We look forward to response. Yours truly, Cliff liams.

Belmont Homes, Inc. P.Q. Box 2401 Kirkland, WA 98083-2401 Re: Talbot Ridge Estates Preliminary Plat King County Road Variance File No. I_05VO066 Dear Mr. Williams: At your request, we have prepared this response to the email dated June 19, 2006 from Craig Comfort of King County regarding the above -referenced sight distance variance request for the existing SE 192" d Street/102nd Avenue SE intersection. A copy of Mr. Comfort's email is attached. Entering sight distances (ESD) and stopping sight distances (SSD) at this location have been discussed in detail in our Entering Sight Distance Variance Request letter dated August 11, 2005, the King County review comment letter from Peter Dye dated September 23, 2005, our response letter dated November 18, 2005, the email from Craig Comfort dated December 13, 2005, and our response letter dated April 18, 2006. Mr. Comfort's June 19, 2006 e-mail is supportive of the proposed vertical realignment of SE 192"d Street ,at the 102"d Avenue SE intersection in order to improve the SSD. However, the email identifies three roadway design issues, and requests additional information. We have prepared the following responses to the three issues discussed in the email: The proposed roadway design will include appropriate pavement tapers. This is likely to include a tapered paved transition on the south side of the road east of the intersection. 2. The proposed roadway design will include shoulders. 3. Attached is a table identifying seven existing residential driveways within the proposed roadway reconstruction project limits. As requested, the table shows SSD and ESD for all the driveways. The sight distances were measured in both directions for both the existing and proposed roadway conditions. The SSD was measured for both a six -inch -high object and a two -foot -high object. Most of the sight distances were measured in the field, although some of the sight distances for the proposed roadway conditions were measured on the proposed roadway profile due to significant elevation changes.

Belmont Homes, Inc. August 10, 2006 Page 2 All seven of the existing driveways have existing SSD and ESD deficiencies. The proposed roadway reconstruction project will improve the SSD at the first three (easternmost) driveways, so that they will meet the SSD requirement. All of the driveways will continue to have ESD deficiencies, particularly looking to the west. However, the roadway reconstruction project will improve the ESD at three of the driveways. As noted in Mr. Comfort's e-mail, there will be two driveway adjustments within private property on SE 192" d Street west of the intersection that will require permission from property owners to allow regrading of the driveways within private property. These are on the north side approx. 175' west of the intersection (10042 SE 192nd Street), and on the south side approx. 300' west of the intersection (10033 SE 192"d Street). I understand that you are in contact with the property owners regarding their willingness to allow the regrading of their driveways.

I was directed to evaluate problems with the proposed offsite grade realignment and to check our accident history. 1 went to the site last week and met with DDES staff then the County Traffic Engineer. I have the following issues that must be resolved: (11)There appears to be a jog in the centerline due to the widening to the south of the curbline along your frontage. Your plans do not show it, but I assume a tapered paved transition would be provided at the southeast side of the intersection to direct eastbound traffic back to the road in the north side of the ROW. 2. Your road section for the offsite reconstruction of SE 192nd Street does not appear to include shoulders in several areas. I will include language in the variance that DDES will be determining the cross section per 1,03 KCRS. 3. There appears to be two driveway adjustments on SE 192nd Street west of the intersection that will require permission from property owners to allow regrading of the driveways within private property. One driveway is on the north side 165 feet from the intersection and the proposed road grade is 3 feet above the driveway. The second driveway on the south side is proposed immediately to the north of your Lot 18. It is a loop driveway with 5 feet of elevation difference to the final road grade at the east connection. The west connection has severely limited sight distance and consideration should be given to eliminate. DDES could be consulted concerning a potential connection through your plat to the offsite lot. Please provide letters from these property owners showing their willingness to allow regrading of the driveways. Also evaluate the ESD and SSD (approaching) for all affected driveways along the road reconstruction. Please call me if you have questions (206) 263-6109. Please resubmit the requested information within 60 days or your variance will be deactivated or denied.

But if he is saying that we can, that takes the superelevation issue out of play, but still leaves the SSD . The attached exhibit shows the superelevation runoff calculations. The numbers in red are my talcs for the 06/ 19/2006 Message Page 2 of 3 original 6% super, the numbers in purple are my calcs for a 3% super. It appears that we can reduce our -paves'nent width to 16 feet. I'm showing 18 feet for some reason. With that change the runoff length would be 70. What this means is that the transition from normal crown to super begins (or ends) at 96 feet (49' + 47') from the PC (or PT). The PC is at station 11 +03.72, so the super runoff would begin at 10+07.19. The PT is at 13+41.72 so the normal crown would begin again at 14+37.72. These are within the beginning and end of the proposed work area. Aren't you glad that your part of this email train, Bob?

Box 2401 Kirkland, WA 98083-2401 Re: Talbot Ridge Estates Preliminary PlatDD King County LUSD File No. L05P0007 AUG 2 tuu Entering Sight Distance Variance Request Dear Mr. Williams: K.C. D.D.E.S. We have prepared this request for a Variance from the Road Standards for the existing Entering Sight Distance (ESD) deficiency on S.E. 192" d St. to the west of 102" d Ave. Southeast. This request was prepared in response to the Traffic/Roads items in the Plat Screening Transmittal from King County dated June 28, 2005. The County's information request was in response to our Traffic Impact Analysis (TIA) report for this project dated March 21, 2005. An existing ESD deficiency on S.E. 192nd St. to the west of 102"d Ave. S.E. was identified and discussed extensively in the TIA (pages 2 — 4). We conducted a sight distance review on S.E. 192" d St. for the northbound approach on 102"d Ave. Southeast. The results of the available stopping sight distance (SSD) and entering sight distance (ESD) measurements at this intersection are shown in the following table: Type of Sight Distance To/from the TcVftm the King County East West Design Criteria Stopping Sight Distance (ft. ) Over 500 Approx. 320 * 250 Entering Sight Distance Over 800 Approx. 340 490 (ft. ) SSD to 24" high object per current AASHTO standards. Due to crest of grade on the west edge of the intersection, the SSD to a fi" high object is approximately 140 feet. This table also shows the King County Design Criteria for SSD and ESD per Table 2.1 in the King County Road Standards -1993 (KCRS).

Belmont Homes, Inc. August 11, 2005 Page 2 recommended sight distances are for a design speed of 35 MPH. Per County policy, the design speed is the posted speed limit (25 MPH on S.E. 192"d St.) plus 10 MPH (total of 35 MPH design speed). Our field review shows that the County s, SSD criterion of 250 feet is met both to the east and west along S.E. 192"d St. at the 102"d Ave. S.E. intersection. For the northbound approach to the intersection, the County's ESD criterion of 490 feet is also met to the east. However, to the west of the 102"d Ave. S.E. intersection, the existing available ESD along S.E. 192"d St. was measured to be approximately 340 feet. The sight distance is limited by vertical obstructions on the north side of S.E. 192"d St. on the inside of a horizontal curve in the roadway. The initial obstruction is a line of five Douglas fir tree trunks, ranging in diameter from about 8" to 20". The lower branches have been removed, so increasing the sight distance would require removal of the trees themselves. The trees are located back from the roadway, near the right-of-way line, and appear to be within the County right-of-way. It is estimated that removing these five trees would increase the ESD to approximately 370 feet. Since this is a gain of only about 30 feet of ESD, removal of the trees does not appear to be worthwhile. If the trees were removed, the sight obstructions would then become the private fences located on or near the County road right-of-way line. Additional structures and vegetation located on private single family residential properties north of the fences would also need to be removed in order to further increase the ESD. Removal of these structures and vegetation would require the purchase of additional property or easements from the homeowners on the north side of the road. This would be expensive, time consuming, likely involving legal complications, and ultimately impractical. The existing ESD deficiency on S.E. 192"d St. west of the 102"d Ave. S.E. intersection is mitigated by the existing roadway geometry and the existing traffic control devices installed and maintained by the County. Southeast 192"d St. climbs the hill from Talbot Rd. S. up to 102"d Ave. Southeast. The road was constructed with a series of horizontal curves and "hairpin" turns winding up the hill. The grade crests at the west edge of the 102"d Ave. S.E. intersection, then the road is relatively level through the intersection and continuing to the east. About midway between the intersection and the first horizontal curve located to the west, the grade on S.E. 192"d St. approaching the intersection eastbound was measured to be approximately 9%. K0433205FSDve-Owce. doc T'-;p—LaLi— Pla. iL,g 6 Enginering Cliff Williams, P.E. Belmont Homes, Inc. August 11, 2005 Page 3 As noted in the County's Plat Screening Transmittal, S.E. 192"d St. is an unclassified (i.e. not an arterial) roadway. The posted speed limit is 25 MPH. West of the 102"d Ave. S.E. intersection, S.E. 192"d St. is well posted with turn and winding road warning signs with 15 MPH advisory speeds for both directions of travel. The eastbound approach to the 102"d Ave. S.E. intersection is also posted with a cross road warning sign with a 20 MPH advisory speed. The existing roadway grade, horizontal turns, and traffic control devices reduce the speeds of eastbound traffic on S.E. 192"d St. approaching the 102"d Ave. S.E. intersection. The accident report data provided by King County staff for the four-year period from January 1, 2000 to December 31, 2003 showed only one accident at the S.E. 192"d St./102"d Ave S.E. intersection. The accident was a right angle accident that occurred at 8:20 PM at night on 11/13/03 and resulted in property damage only. The direction of travel of the vehicles involved is not apparent from the data provided. However, since the accident occur -red at night, and vehicle headlights would have been on, ESD does not appear to be a factor in this accident. Further improvements to increase the ESD west of the intersection do not appear to be worthwhile or practical. Due to the limitations of the available right-of-way and the existing topography, widening or relocation of S. 192"d St. to mitigate the existing ESD deficiency does not appear to be feasible. The current SSD criteria are met. ESD does not appear to be a factor in any traffic accidents at the intersection. For these reasons, we believe that the County should grant a Variance from the Road Standards for the existing Entering Sight Distance (ESD) deficiency on S.E. 192"d St. to the west of 102"d Ave. Southeast.

Box 2401 Kirkland, WA 98083-2401 Re: Talbot Ridge Estates Preliminary Plat King County Road Variance File No. L05VO066 Dear Mr. Williams: At your request, we have prepared this response to the e-mail dated December 13, 2005 from Craig Comfort of King County regarding the above -referenced sight distance variance request. Mr. Comfort's e-mail is supportive of the variance request for the existing entering sight distance (ESD) deficiency at the S.E. 192nd St./102nd Ave. N.E. intersection. However, the e-mail requests additional information on the existing stopping sight distance (SSD) deficiency on S.E. 192"d St. at the intersection. The e- mail also requests additional information on the existing horizontal curve on S.E. 192nd St. west of the intersection. A copy of Mr. Comfort's e-mail is attached. ESD and SSD at this location have been discussed in detail in our previous Entering Sight Distance Variance Request letter dated August 11, 2005, the King County review comment letter from Peter Dye dated September 23, 2005, and our response letter dated November 18, 2005. S.E. 192nd St. Design Consideiradons As discussed previously, urban frontage improvements to the site frontage on S.E. 192nd St. are proposed for this project. The proposed front face of curb would be 18 feet from the S.E. 192nd St. right-of-way centerline. The curb return at the intersection comer would have a 35 foot radius. Increasing the SSD on S.E. 192"d St. by lowering the roadway to increase the vertical curve length is not feasible due to the existing underground utilities. Existing utilities under the S.E. 192"d St./ 102nd Ave. N.E. intersection include a fiber optic cable bank, a high pressure gas line and a water line. Lowering the intersection would also require reoonstruction of 102nd Ave. N.E. both to the north and to the south in order to match the lowered S.E. 192"d St. profile. Several driveways would also need to be lowered to match the revised street profiles. Therefore, two alternative profiles have been developed that would increase the SSD on S.E. 192n° St. by raising the roadway to increase the vertical curve length. The first altemative profile would meet the County's SSD requirement using the 6° object x0M205ssa,rar1&m.dx Mfrs/ Associates, Inc. 0 11410 NE 122nd Way, Suite 320 0 Kirkland, WA 98034-6927 0 425.820.0100 . t 0 425.821.1750 - f •I Transportation Planning 6 Engineering Cliff Williams, P.E.

The second alternative profile would meet the County's SSD requirement using the 2' object height, which is the current AASHTO standard for SSD per Chapter 3 of the AASHTO Geometric Design of Streets and Highways. The two alternative plan and profile exhibit drawings were prepared by CORE Design and are dated March, 2006. The drawings show the existing plan and profile of S.E. 192nd St. based on field survey information gathered by CORE Design. The profiles were created from survey information along the existing roadway pavement centerline. The existing roadway pavement is not centered on the right-of-way centerline, but is offset to the north. The proposed site frontage improvements are offset from the right-of-way centerline, per typical roadway design practices. The two alternative plans and profiles are shown on the two exhibit drawings that are discussed below. 6" Object Height Exhibit Drawing Enclosed is the 6" Object Height Exhibit drawing prepared by CORE Design. The drawing shows the existing plan and profile of S.E. 192"d St. as well as a centerline profile and preliminary grading that would meet the County's SSD requirement assuming a 6" object height. As shown on the drawing, the vertical curve calculations are based on a 35 MPH design speed, a 250' base SSD, a 5.95% average downslope and a 29.75% grade correction factor, resulting in a 324' required SSD. The profile of S.E. 192"d St. shows an 864' vertical curve, approximately matching the existing elevation at the 102nd Ave. N.E. intersection. The vertical curve would require fills of up to about 4' deep to the west of the intersection, and up to about 3' deep to the east of the Intersection. The profile would require reconstruction of at least 1,100' of S.E. 192"d St., extending at least 572' west of the intersection and at least 500' east of the intersection. 2` Object Height Exhibit Drawing Also enclosed is the 2' Object Height Exhibit drawing prepared by CORE Design. The drawing shows the existing plan and profile of S.E. 192"d St. as well as a centerline profile and preliminary grading that would meet the County's SSD requirement assuming a 2' object height. As shown on the drawing, the vertical curve calculations K"33206SSDv&* M.dX • Transportation Planneng E. Engineering Cliff Williams, P.E. Belmont Homes, Inc. April 18, 2006 Page 3 are based on a 35 MPH design speed, a 250' base SSD, a 5.2% average downslope and a 26% grade correction factor, resulting in a 315' required SSD. The profile of S.E. 192"d St. shows a 440' vertical curve, approximately matching the existing elevation at the 102" d Ave. N.E. intersection. The vertical curve would require fills of up to about 5' deep to the west of the intersection, and up to about 1' deep to the east of the intersection. The profile would require reconstruction of approximately 700' of S.E. 192"d St., extending 450' west of the intersection and 250' east of the intersection. The 2' object height is the current AASHTO standard for SSD per Chapter 3 of the AASHTO Geometric Desii an of Streets and Highways. This object height is "equivalent to the taillight height of a passenger car." The "Criteria for Measuring Sight Distance" section of the AASHTO document goes on to state: Stopping sight distance object. The basis for selection of a 600-mm (2. 04) object height was largely an arbitrary rationalization of the size of an object that might potentially be encountered in the road and of a driver's ability to perceive and react to such situations. It is considered that an object 600-mm (2.0-f .) high is representative of an object that involves risk to drivers and can be recognized by a driver in time to stop before reaching it. Using object heights of less than 600-mm (2.0-ft.) for stopping sight distance calculations would result in longer crest vertical curves without documented safety benefits (4). Object height of less than 600-mm (2.04) could substantially increase construction costs because additional excavation would be needed to provide the longer crest vertical curves. It is also doubtful that the driver's ability to perceive situations involving risk of collisions would be increased because recommended stopping sight distances for high-speed design are beyond most drivers' capabilities to detect small objects (4). SSD Object Height Variance Request for S.E. 192nd St. The Applicant does not proposed to implement the roadway plan and profile shown on the 6" Object Height Exhibit drawing due to the excessive reconstruction of S.E. 192"d St. that would be required. The length of reconstruction of S.E. 192"d St. is likely to be more than 1,100', which is much longer than the other alternative. Constructing a 3' fill to raise the roadway east of the intersection in an area that is relatively Bat is a somewhat unusual concept, and may not fit well with the adjacent roadsides. The fill would impact additional driveways that would need to be adjusted to K0433205SSDva►ilanae. dx Transpovtstion Planning & Engingaring Cliff Williams, P.E. Belmont Homes, Inc. April 18, 2006 Page 4 grade. Existing power poles and other utilities would likely require relocation or adjustment due to the roadway till. Due to the more extensive construction, this altemative would also likely require a longer construction time period. This would cause more disruption to traffic flow on S.E. 192ndSt. and more impact to local residents. Therefore, the Applicant proposes to construct site frontage improvements and reconstruct S.E. 192"d St. in accordance with the plan and profile on the enclosed 2' Object Height Exhibit drawing. A variance is requested from Section 2.12A. of the KCRS to allow the 2' object height for the SSD requirement, rather than the 6" object height. The 2' object height is the current AASHTO standard for SSD, per Chapter 3 of the AASHTO Geometric Design of Streets and Highways, as discussed above. The plan and profile shown on the enclosed 2' Object Height Exhibit drawing would provide a substantial improvement to the existing SSD deficiency on S.E. 192nd St. at the existing 102"d Ave. N.E. intersection. Horizontal Curve Superelevation Variance Request for S.E. 192nd St. The December 13, 2005 e-mail from Mr. Comfort also requests additional information on the existing horizontal curve on S.E. 192nd St. west of the intersection. The existing horizontal curve radius is 360 feet. The existing roadway pavement does not appear to have any superelevation. For the standard superelevation of 6% per Table 2.02 of the KCRS, Table 2.1 of the KCRS requires a 380' minimum radius for a horizontal curve with a 35 mph design speed. However, increasing the radius of the existing horizontal curve to 380' is not feasible due to the constraints of the existing roadway, existing right-of-way, and other existing roadside improvements. Per Table 2.1 of the KCRS, for a 35 mph design speed the minimum horizontal curve radius is 350' assuming an 8% superelevation (maximum allowable on arterials, but which requires approval of the Engineer). However, an 8% superelevation would be excessive for this road at this location. The standard superelevation for arterials is 6% per Table 2.02 of the KCRS, and increasing the superelevation to 8% requires the approval of the Engineer. A series of sharper horizontal curves exists just down the hill, beginning approximately 150' to the west. As noted in the traffic study, S.E. 192"d St, is well posted with turn and winding road warning signs with 15 mph advisory speeds for both directions of travel. The eastbound approach to the 102"d Ave. N.E. intersection is also posted with a cross road warning sign with a 20 mph advisory speed. Also, an 8% K0433205SSDv&Yar".d0o MOM: �� Trunsportetion Ij Planning & Engineering Cliff Williams, P.E. Belmont Homes, Inc. April 18, 2006 Page 5 superelevation would require a deeper fill on the south side of the road and further exacerbate the side slope design problem. Therefore, the Applicant proposes to construct site frontage improvements and reconstruct S.E. 192"d St. in accordance with the plan and profile on the enclosed 2' Object Height Exhibit drawing. A variance is requested from Table 2.1 of the KCRS to allow the standard superelevation of 6% on the existing 360' radius horizontal curve. The plan and profile shown on the enclosed 2' Object Height Exhibit drawing would provide a substantial improvement to the existing horizontal curve superelevation on S.E. 192nd St. west of the existing 102nd Ave. N.E. intersection.

Craig C. r 06/07/2006 0 King County Department of Development and Environmental Services 900 Oakesdale Ave. Southwest Renton, WA 98055-1219 September 23, 2005 Cliff Williams P.O. Box 2401 Kirkland, WA 98083-2401 RE: Road Variance Pile No: L05VO066 Project: Talbot Ridge Estates Dear Mr. Williams: A road variance application regarding sight distance for the Talbot Ridge Estates subdivision was received by our office on August 25, 2005. Based upon preliminary review of the design issues, additional information is required before final processing of the variance application. In order to continue our review, please address the following information and submit three copies each of any required design drawings or technical analysis. a. To evaluate the sight distance requirements for SE 192"d Street, please submit a traffic speed study prepared by a Qualified traffic engineer. The study shall determined the 85t` percentile speed for vehicles traveling east bound on SE 192"d Street at a location where vehicles come into view from the intersection. This study must include a sample size of at least 100 eastbound vehicles. b. Based upon requirements outlined in King County Road Standards (KCRS) 1.03B, King County requires urban frontage improvements for the proposed subdivision; however, the site plans submitted with the variance application do not show the required road improvements along SE 192"d Street. If frontage improvements are not proposed for any portion of the subdivision, this design issue must also be included in your variance application. c. To evaluate the urban frontage improvements and intersection design, please provide a design plan showing the curb radius and pavement widening for SE 192nd Street. A plan view showing sight distance measurements shall also be prepared_ for the intersection to evaluate sight line locations in relation to vehicle locations, limits of right-of-way, and the removal of vegetation noted in the variance summary. The sight lines must be evaluated based upon the object locations and other design requirements outlined in KCRS 2.12 and 2.13. Cliff Williams September 23, 2005 Page 2 c. As noted in the summary provided with your variance submittal, a crest curve on SE 192"d Street limits the stopping sight distance on SE 192"d Street. Your application indicates that King County standards for stopping sight distance are satisfied based upon AASHTO standards; however, King County does not recognize the AASHTO standards unless approved through the variance application. To provide further evaluation of stopping sight distance, please provide a road profile of SE 192"d Street with sight line measurements showing the sight distances and height of objects being used for the measurements. The road profile must also be evaluated for compliance with standards as related to construction of urban frontage improvements along SE 192"d Street. All required urban road improvements must be located on vertical and horizontal curves meeting County standards unless otherwise approved by the variance. The Land Use Services Division will hold your application in abeyance pending receipt of the above information. The deadline for submitting the required information is November 23, 2005. Should you have any questions, please contact me at 206-296-7185. Sincerely, yet, ye, P.E.
