24332 76TH AVE W11111111111111 15160 24332 76TH AVE W RECEIVED FEB 2 - 2001 ENGINEERING DIVISION RECEIVED January 30, 2001 JAN 3 1 2001 r Mr.Duane Bowman Development Sercvices Director DEVELOPMENT SERVICES City Of Edmonds �5 Washington Dour � Dear Duane: D -J� � tt�J For the past three weeks I have been concerned about the `a development of a lot on the west side of 76th W just two lots north of 205th better known as the County line. This is a lot the City owned for many years. It was acquired when the State wanted to widen 76th which was back in the late sixties or early seventies. The lot has had a beautiful stand of fir trees which.,'% date back more than the 40 years we have lived in the Ballinger, V area and now tey are gone. I became concerned for several reasons of which many were 1 answered by Jeannine Graf - my compliments to her effort. "`� However there are other concerns and although I visited the. d0 ., City offices today I am not satisfied and so am asking for your 1Jr V help. For the many years I served on the Council we always honored approx. 300 feet�on both the north and south side of the County line. One side being King County the State required this footage <- for the alignment and lane development. This was their territory. On the first of my two visits to the City I asked —cif the State had been contacted for the project under developmentit would require a curb -cut: it would require whoever was entering from the south to turn left across two and borderline three active lanes to enter to property and conversely.whoever was leaving the site to travel to I-5 would have to cross exactly the same lanes. The answer I received and these answers from here on will not involve Jeannnine - said I didn't know we would have to contact the State. I called the State and they said they did not know what was going on. I then contacted Chief Hickok of the Edmonds Police department and he said he had no idea what was going on and had not been c� contacted. He asked if I could go with him to the site. This ° we did and he said he was surprised but the departments "seldom " contact the police department regarding traffic impacts X Then I asked what the zoning on the property was and on my first C visit Rob Chaves sent a message out with Jeannine that the zoning had been changed - my memory states that it has always been BN. if So I asked for further clarification and a person by the name Duane Bowman Community Services Director Page two January 25, 2001 of Chanda went to work for me and on two occasions came back with this comment " there have been no rezones since the zoning designation of the Comprehensive Plan (1982), for the property you indicated to me." I asked on both occasions and in a memo to the City Clerk for copies of any zoning changes that were made aside from the BN zoning already quoted. None have been presented. I contacted Community Transit to see if any one in to the traffic department had been contacted by the City of Edmonds as the development of this lot and they had not. The concern is that this is where the buses come to a stop or slow down prior to ascending the hill to 205th. As stated before the stability of the rockery was a question of mine however I was assured that a geo tech studay was to be done and the question be addressed. ( I remember when the Gulf Oil Company built that station -.it was just stacked boulders and fill - no geo tech process existed at that time. Lastly - there is an ingress and egree to the service station immediately to the south of this property. Focusing on the egrees from this service station driving north on the wrong side of 76th until the lane clears a short distance down the hill. In reading EDC Chapter 16.40 I have read A - E and see no application in any of these paragraphs that fit what I was told would be the use of the property - warehouses. I am told that major trucks will be entering and exiting to deliver. Having spent a few years cities' zoning applications - if what I hear and read is correct this has the makings of a major mess. I would appreciate hearing your response and would welcome the opportunity to meet with you in your office to discuss the proposal. I plan to share this with the Council however in respect to your position I would like to chat with you first. By the way it was good to see you back in the City again.

Edmonds, WA 98026 Dear Mr. Nordquist: A copy of your letter to Duane Bowman dated January 301h has been forwarded to me. I will take a crack at responding to some of the Planning -related items for you. I believe you are referring to property located at 24342 76th Avenue West, which is the 2"d lot north of the SR- 104/76`h Avenue intersection on the west side of 76`h Avenue. I do recall Jeannine asking about the property while you were at the counter. Actually, I did not say the property was rezoned; I said that the property is currently zoned BC. Jeannine indicated you were certain that it had been zoned BN at some time, so I said that if that was the case, it had to have been changed at some time since it's current zoning is now BC. I've checked, and the property has been zoned BC since at least 1981, when the current city-wide zoning map was adopted by Ordinance #2182. Of course it's possible that the zoning prior to 1980 was BN at some point in time, but there is no property - specific rezone from BN to BC for that location shown in our computer permit history. I would be happy to try to find out more history if you would like. Regarding development on the site, there was an ADB application for the property filed in October, 1999 (file #ADB-1999-205). The applicants were Ron & Renee Knowles. The project involved a 3-building mixed -use complex, with the primary business being a "company setting up large warehouse store display racks ... The primary function of the commercial areas within the buildings will be to house the parts, tools, and distribution vehicles along with a small office space for the bookkeeper." There were also to be three apartment units on the site, consistent with the BC zone. The project application (ADB) was routed as usual to Engineering, Fire, Public Works, and Parks & Rec for comment in October of 1999. A SEPA determination (DNS) was issued on February 4, 2000. Public notice was provided to all properties within 300 feet, and the ADB held a public hearing and approved the project on March 15, 2000. Incorporated August 11, 1890 Nordquist 2.2.2001; page 2 Engineering's review included a traffic impact analysis prepared by the applicant. One condition required by Engineering was to restrict access to 76th to a right -in, right -out turning movement. WSDOT was contacted by Engineering during their review, and DOT did not provide any comments (DOT "waived review" because of the minor scale of the proj ect). Regarding the uses on the property, the BC zone (ECDC 16.50) allows "retail stores, offices and service uses, excluding intense uses, such as trailer sales, used car lots, and heavy equipment sales and services;" the proposed use fits into this general category of permitted uses. "Multiple dwelling units(s)" are also permitted so long as they are not on the ground floor. I hope this helps.

Mellor, P.E. WAS w 19343 EXPiREs 2/24/ 0 i TrWnowles • • DEVELOPED SITE TRANSPORTATION/TRAFFIC IMPACTS Trip Generation — Peak Hour Trips The application to the ADB board list the uses of the proposed mixed use building to include 3 apartments, an office, storage, and parking. Peak hours trips from the apartments will range from 1 to 2 trips per unit. To obtain a count of peak hour trips from the apartments an average of one and a half per apartment will be used, with a total of 4.5 peak hour trips The other addition to peak hour traffic will be that, to and from the office, and a once or twice a week loading or unloading of construction materials or tools for projects for SAF Inc. personnel. To determine peak hour trips to and from an office the January 1991, ITE trip generation manual will be used, page 223. The manual uses a value of 4 peak hour trips per 1,000 square feet of gross floor area. With an area under consideration of less than a thousand square feet the suggested peak hours trips would be approximately 4. The result is a generation of 4.5 + 4 or 8.5 peak hour trips on to 76t' Ave W. Site Distance The gross area of the site is 13,085 sq ft or 0.3004 acres with an 80' frontage. The driveway access to this proposed development is from 76"' Ave W. The access point is approximately 170 —180 feet north of the intersection of 76t' Ave W and SW 244t' Street. Sight distance is unimpeded, across the width of 76"' Ave W, to the south, toward the previously described intersection. Sight distance is also unimpeded to the north along the entire width of 76"' Ave W for perhaps 1,000 feet or more. Right Hand Turn Channelization The subject site fronts onto 76t' Ave W at the point where the widening begins for the southbound right-hand turn. The beginning of the painted stripe for the right hand turn channelization occurs a dozen feet or so south of the south edge of the subject property. Staging and Parking An agreement has been reached for the use of the Seattle Baptist Church property adjacent to the north and west of the subject property for staging and parking of equipment and materials. Frontage Improvements and Required Dedication for NE 191St Street Frontage improvements are in place presently. Only a driveway cut will be required to provide access and egress to the subject site. No dedication has been requested for this proposal. STORM DRAINAGE & GRADING ISSUES Water Quality and Quantity Water quality and quantity will be addressed during the engineering for the subject project. Existing Rockery Along South Property Line During engineering for the subject project all consideration will be made for any drainage impacts on the adjacent rockery. Any excavations made at or near the base of said rockery will follow the recommendations of the Dodds Geotechnical report. Adequate margins of safety will be observed due to the severe rammifications connected with the loss of said rockery. 2 Mini -Warehouse (151) Average Vehicle Trip Ends vs: 1000 Sq.

The front portion of this property is moderately sloped with a an average slope of - 10%. The rear portion has an average slope of - 20%. The most severe slope is found toward the south center portion of the site with average slopes of 38%. A rockery exists just a few feet south of the south property line. The heights of this rockery range from 5' at the west end to 19.5' at the east end. The acreage of the subject property is: 13, 085.6618 sq ft = 0.3004055 acres 43,560 There are no existing impervious surfaces presently on the subject site. The existing pervious area of the subject site is covered with a grass, brush and a dozen or so trees mostly coniferous..

The new structure and asphalt areas will cover all but 13,085.66 — 11,444.97 = 1,640.69 sq ft of the site. The developed site will contain 11,444.97 sq ft or 0.2627 ac of new impervious surfaces, and 1,640.69 sq ft or 0.0377 ac of landscapped areas. The longest time of concentration for the developed site is based on the runoff time from the west end of the driveway, to the catch basin at the upper portion of the detention system, and through the detention system: Tt = 0.42 ngQ0'8 where Sol = driveway slope = 2.8024% (P2) ' (SO)0.4 L = length of driveway run = 35.68' nS= 0.011 Manning's coeff.

To provide treatment of storm runoff from asphalt paving subject to vehicular use, the detention system will be a wetpipe type detention system. This detention system includes a 4' diameter 36.33' long CMP pipe and with required appurtenant structures. The bottom 1.5' of the detention pipe will provide dead storage for the capture of water borne pollutants. The King County SBHYD and RDFAC analyses were used to determine detention requirements. They are contained at the back of this report. 3 s Checking Detention Capacity It can be demonstrated that the areas of the detention pipe at the upper and lower end of a 36.33' 48" detention system with a dead storage of 1.5' are 8.9561 sq ft and 8.2622 sq ft respectively. This detention pipe will provide (8.9561 + 8.2622)/2 = 8.6091 cu ft per ft of detention pipe. Additional storage will be provided by a 48" Type II catch basin with a restrictor with a live storage depth of 2.69'. At the other end of the detention system another 48" Type II catch basin with a live storage depth of 2.50'. The storage of the entire 48" CMP detention system is 801.361 cu ft, which is sufficient to meet the storage requirement of 325 cu ft. 48" CB live storage depth 2.69 ft x 12.566 cu ft/ft ...................................... 33.802 cu ft 2'(36" CMP) x 7.068 cu ft/ft ........................................................................ 14.137 cu ft 36.333'(48" CMP with dead storage) x 8.6091 cu ft/ft .............................. 312.794 cu ft 2'(36" CMP) x 7.068 cu ft/ft ...... :................................................................ 14.137 cu ft 48" CB live storage depth 5.00 ft x 5.778 cu ft/ft ................................... 31.415 cu ft 406.285 cu ft Water Quality Water quality is addressed with the use of a wet pipe type detention system. Offsite runoff, from the rockery located along the south property line could have an impact on this project. A method for storm runoff collection and removal will be incl in the engineering plans. Check Riser Overflow Capacity The flow to check is the 100 year storm, Qloo = 0.24 cfs. From the formula QWEiR = 9.739DH3/2 ; where Q is in cfs, D is in feet(dia) and H in feet, an 8 inch riser can discharge 2.2955 cfs, with 6" of head Therefore 0.24 cfs is a conservative discharge. 4 1 • S.C.S.

I have had the opportunity to visit the site and review the criteria required for a determination as to whether a critical area exists on site. At first glance the property would appear to be adjacent to a steep slope on the south east corner of the site. After reasearching topographical maps in house, I have determined that this slope was a rock wall constructed to retain fill and not a steep slope. As a result, I am assigning this site with the determination of "waiver". City of Edmonds cQ Planning Division ^ENVMEMO.DOC 09/22/98.
