OVERVIEW The proposed project is a 3 lot shorf plat located along the west side of Aberdeen Ave. NE. The site address is 1901 Aberdeen Ave. NE. The property has an existing house, detached garage, large deck and several large trees throughout the properfy. The existing lot has a total area of 19,914 SF, or 0.46 acres. The site is currently zoned R-8. The proposed shorf plat would divide the existing lot into 3 new single family, detached residentiol lofis. The existing site is generally covered with grass and the several large trees. The tree plan is shown on the erosion control plan. The site is fairly open without a heavy underbrush cover. The lot has an average slope of approx. 9% down from the east to the west in the rear (west) porfion of the site. The center and west parf of the property is more flat with a very slight slope down to the west, away from Aberdeen Ave. NE. The west property line is the lowest with the southwest property corner as the lowest point on the properfy. The site has been surveyed and the topography is shown on the engineering plan set. The existing frontage along Aberdeen Ave. NE is an asphalt paved road that has marked fog lines at the lane edges. The shoulder consists of asphalt and gravel. There are no curb, gutter or sidewalk improvements along this section Aberdeen Ave. NE. This property has been granted a waiver not to install curb, gutter and sidewalks along the frontage of Aberdeen Ave. NE. Therefore, no frontaae improvements are shown on the plans. There are no drainage facilities within this porfion of Aberdeen Ave. NE. The shorf plat will provide access to all three lots from a private road easement connected to Aberdeen Ave. NE. This easement will be 18�� tong along the norfh property line, west of the Aberdeen Ave. ROW line It will be 20' wide, asphalt surfaced. It will benefit future lots 2 and 3. The proposed driveway and individual lots will drain into individual infiltration systems. The infiltration system for the private road will be located under the private road, within the easement. The new houses will utilize individual lot infiltration systems located on the respective lots. The existing house on lot #1 will remain. New houses will be constructed on lots #2 and #3. � Page 1 of 2 King County Bullding and Land Development Dlvlsion � TECHNICAL INFORMATION REPORT (TIR) WORKSHEET - . . �- � - . . . - . � � � . �«-, • . � �ju jsv I Project Name O U �,S'a S f-1 c�t�T �L� � , Project OK�ner I � Address �� -� e�n1�'�m � Location � I Phone _ 2-E-� �S ' � Township Z.3 � � Ran e � Project Engineer �0.Y`r�PS �C�..e 9Ji-� 9 ; Sec1 ion , Company � �%�� Project Size �� 4-�c C � IAddress hone 'S' � R- � Upstream Drainage B�sin Size U AC ', l 2�37 �iSv- c�43� • 4�bo3� ! , • • �- ,� • . �- • �- � i I i � � �J Subdi�-ision � � � DOF/G HPA � Shore;ine A`anaoemer.t � �Short Subdivision i ' Ci COE<OA � Rockery I � � � Gradin g i C J D O E D am Sate ry l� S;ruc'ur�;1'a.;:;s � Commercial O FEh4A Floodp,ain � O�hc' � � Oiher i � � COE 1^Jetlands 0 H�" ..�i,l, i � �� • . , . �� co,�,T��:� C►T`l c�F ��tii , - - D�2inZC�e B2s�n ' . 1 --��s SZ_��1�-� l��I t�1_��U l�'-- - « �-�� .., - - . . ,. „ . �. ._ ��:.-z. s.m..%.,.��u.�;.� �:�� ...�_ _. `I River `J Floodp. � � Strearn �; 1"Jetlan�� I - — - I U Critical S:ream Reach _: Seeps�Springs ; � Depressions/Swales r,_; High Groundwater Ta:: � ; � LaJ<e - -- GrounCwater Recharc• C' Steep Siopes _- Other ______� � Lakes ce;'Erosion H�a�d , r �lpN� ..;. �- - ��: - 'Y: �;�, - - �-,.

Discharge at Natural Locotion: �'I The existing site runoff is to the west, away from Aberdeen Ave. NE. '', However the soils within the property are very sandy and extremely ' pervious. The sheet flow across the site infiltrates into the soil prior to , leaving the property. The proposed drainage system will use infiltration. ' As such, the existing discharge location is not changing. 2. Off-Site Analysis: A downstream drainage analysis is not necessary because the developed site drainage will utilize 100% infiltration. 3. Runoff Control: This project is exempt from peak rate runoff control because the 100 year peak developed runoff is less than the limit of 0.5 CFS greater than the peak pre-developed runoff rate. The actual difference is 0.16 CFS. 4. Conveyance System: There are no existing drainage improvements on the site. There also are no drainage improvements within the frontage road near the site. As such, the proposed shorf plat does not show any conveyance system, other than the new driveway gutters. The new houses will utilize individual lot infiltration systems. 5. Erosion and Sedimentation Control Plan: An erosion control plan has been prepared for this site. Grading activities will not be required except for the building foundations for Lots #2 and #3. Silt fencing, catch basin protection, soil cover and dust control will be parf of the erosion control measures. 6. Maintenance and Operation: The maintenance of the private driveway will be joint responsibility of the homeowners on an equal basis. The mutual agreement will be recorded on the final short plat. 7. Bonds and Liability: Any required bonds and insurance will be provided prior to any construction activities. SPECIAL DRAINAGE REQUIREMENTS There are 12 special drainage requirements that may apply to any project. In this case, none of them are applicable to this project. I, r+c�nc.cna�+ yy:1b 7a-N L.

PREDEVELOPED DRAINAGE There are no existing drainage improvements on the site. The site is currently developed with a single family residence. The drainage from the existing site currently infiltrates into the lawn area in the rear and front of the house. The soils are extremely uniform sand. The west property line is the low point of the property. There are numerous trees that are generally throughout the property, generally within lot #1. There is a general ground cover of lawn and shrubs. The drainage calculations include the total site. The site is 19914 SF. , or 0.46 acres was used as the project drainage area for the calculations. The existing drainage analysis was performed using the "Waterworks" hydrology software and its summary tables and charfs are attached for reference. The methods outlined in the King County Surface Water Drainage Manual were used as guidelines. Following this page are the data sheets used for fihe computer input data. The computer summary sheets for peak flow and time of concentration calculations are also attached. Below is a brief description of the existing drainage characteristics: Time of concentration: 14.26 minutes 2 year peak flow: 0.02 CFS ]0 year peak flow: 0.03 CFS 100 year peak flow: 0.06 CFS total area: 0.46 acres pervious area: 0.37 acres curve number: 65 impervious area: 0.09 acres curve number: 98 _ - -- __ �-=='�-#•�'��`'�� -X�-i-n Y�?(2';� � ��-p�� - - - �� _Tt'^� �' S a�,C�U,\W, a�-L'� � _ �1 _ aS Z , � _�_ - _ . - -�� - -- �� z�z � ls `�ar� , -aU�� d- a�.. - �a vsQ,�. �v�, j v�o a _�u.s� . r,.�o� . ,_�,,t� ��2 - , ��5��- -�� , - - ------— J • u _ -------- --- -- - - - --- . �,�� OC1�d�r�� Nc� IC� � �1,� � �� o - b� � a - �; .Q _ - - -a-�� s� � : � ;s�c�o i n.�'� ��.�;t�� --� �10 n''�M�'�� _ r �� ' O _ ---- - �� O f�L� ^ -- -- �.S L�oI = —a��v'� �J =.'.S �L�. = 00� �-S L� :''! �''� ��.S� ��. �,S" �� 1 ; �v C�2n�J►� � aS��-, � �1� � � _ �� ; S c�o I t�-�'a'� L+,A 1 �',� 1�C . �'b � c��u-�.

DEVELOPED DRAINAGE The developed project will include the new joint driveway that will serve new lots #2 and #3. The existing house on lot #1 will remain and two new houses wil! be constructed on lots #2 and #3. The remaining porfion of the developed site will be residential landscaping. The developed drainage will use individual lot infiltration for each of the houses. The site will be exempt from drainage detention because the increase in 100 year peak flow from the pre-developed to the developed condition is less than 0.5 CFS. The actual increase is 0.18 CFS. The areas used to calculate the flows were the same as #hose areas used in the pre-developed drainage calculations. It should be noted that the new houses and the private road will �se infiltration for drainage disposal. The site will be 100% infiltrated. Similar to the existing condition, the SBUH hydrograph method was used to determine the peak flows for the various storm events. A level pool analysis was performed to evaluate the pond performance during the various required scenarios. The computer data sheets for the developed flows follow this page as well as the works sheets and the time of concentration calculations. A brief summary of the developed drainage characteristics are: time of concentration: 5.00 minutes 2 year peak flow: 0.10 CFS 10 year peak flow: 0.16 CFS 100 year peak flow: 0.24 CFS total area: 0.50 acres pervious area: 0.22 acres curve number: 68 impervious area: 0.24 acres curve nun�ber: 98 R ��sso s�o� �P�-�-T -- p��-o �� PR�� a�� l�s� �e. soume c�.re� o�s �.e,�ne� fo r �e �re. -c�.��l e�foP es� - c��t�rac�... , f�-�-a-= p , 4c� ��- - g , � ��F t�l v M t3�2S � C�,� � Ev2�'e��k' S�r�e s.

HYDROLOGIC ANALYSIS The site is exempt from the peak rate runoff control due to the negligible peak rate runoff rate increase exemption. This is specified in the 1990 King County Drainage Manual. The developed peak 100 year runoff flow is 0.24 CFS. The 100 year pre-developed flow is 0.06 CFS. This is a 0.18 CFS difference, which is less than the 0.5 CFS maximum allowed for this exemption. B. DETENTION ANALYSIS AND DESIGN Detention Storage is not required for this project as stated above. C. BIOFILTRATION Biofiltration will not be provided because the new impervious surface subject to traffic is less than 5000 SF. The new private road is 3700 SF. The estimated area of the new driveways for Lots 2 and 3 are 500 SF each, or 1000 SF total. The total impervious subject to traffic is 4700 SF.

Method o( Analysis/Length oi Roof Downspout Infiltration Trenches � The len�th oi trench required is based on the U.S.D.A. soil texture class, the roof area and the site location, using Table 4.5.1 H. The length of trench required is determined by dividinp the roof area by 1000 and multiplyinp by the unit length I from the chart ior the soil type and multiplyinp the resvtt by • the repional scale factor k shown in Figure 4.5.1 D. The trench lenpth L is computed usinp the followinp equation: L = (AR/1000)(I)(k) Where: Aq = area of the roof tributary to the system, ft�. (Note: a typical sinple-tamily residence has a roof area of approximately 2,000 ft�.)

CONVEYANCE SYSTEM There is no conveyance piping proposed for this short plat. The drainage from the joint driveway will be infiltrated into a system under the private road. The 2 new houses will utilize individual lot infiltration systems and thus will not require a piped outlet to the drainage system. VII. ADDITIONAL STUDIES OR REPORTS Design calculations for the individual lot roof downspout drainage systems are attached following this page. VIII. BASIN AND COMMUNITY PLAN AREAS This site is within the City of Renton It is within the East Lake Washington drainage sub-bas �. XI. OTHER PERMITS I Building permits will be required for the 2 new houses. , X. EROSION CONTROL SYSTEM The erosion control system was designed to minimize any contaminated site runoff from entering the adjacent properties or leaving the site. There is little possibility that runoff will enter a neighboring property since there is minimal grading necessary for the development of this site. The clearing limits cover approx. the entire site with few of the trees being saved along the south property line. Clearing for the building pads will be performed at this time. The potential for runoff and mud entering the lot to the west will I, be minimal because the area to be worked is very small. A quarry spall I construction access is shown in the area of the new private road. The site I is small enough and without the need for significant grading, that a sedimentation facility is not warronted. The specific trees that are proposed to be removed are shown on the eros+on control plan. Besides the silt fencing, the erosion control plans also show the clearing limits and the standard erosion control notes for the City.
