I have modified the calculations, and as requested increased the width and added the filter fabric wrap to the trench design. The calculated theoretical length of trench is 8,3 fee for the area proposed to be drained into the system (not including the safety factor or the mitigating effect of void space detention volume). Adding a safety factor of 2 seems excessive, given the fact that the size, topography, and soil type of the property makes it impossible for surface runoff to go anywhere else. If the system were found to be performing inadequately over time, a larger one could be easily built in the space available. Any such failure would not cause property damage, would not affect any downstream system, would not affect any other property, and would only cause the temporary inconvenience of surface ponding during an extreme storm event. Even at a length 83 feet, the system provides a safety factor of 1.6 for a 10-year storm, which is as good as most of the rest of the City's systems. The circumstance of this site justify elimination of the safety factor, but at this point I will defer to your final decision. Finally, I was unable to establish with certainty the total area of impervious surface which will ultimately drain into this system. I recommend that if the area is substantially greater than or less than the assumed 7460 square feet, the system be adjusted by 1.15 feet per 100 square feet of impervious surface, multiplied by whatever safety factor is used. This provides a little flexibility to deal with changes. Please call me if you have any questions on this...n 1;a� Sincerely, 0,6 �-Lt�A.

Method of Analysis/Length of Roof Downspout Infiltration Trenches The length of trench required is based on the assumption of providing a bottom trench area sized to Infiltrate at a rate equal to the rainfall intensity for the peak 10-minute time step for the 10-year, 24-hour duration design storm event (Time step 460 to 470 minutes, 5.4% of total storm volume P,o, see Table 3.5.1A), and by the maximum infiltration rate (1m) which is based on the Soil Texture Class by the United States Department of Agriculture (U.S.D.A.) designation system (see Figure 4.5.16 and Table 4.5.1A). The length of trench required is determined by dividing the required infiltration area (A,) by 4 feet (the two -foot trench widith plus one foot on either side for side wall infiltration). A, is computed using the following equation: Am = (0.054 P,OAO/10 IM �7 osq(�� � U Where: , f a 0 P,o = 10-Year, 24-hour design storm total precipitation, inches (from Figure 3.5."71 IM = the maximum infiltration rate from Table 4.5.1 A. min./inch. % area of the roof tributary to the system, ftz.

I have modified the calculations, and as requested increased the width and added the filter fabric wrap to the trench design. The calculated theoretical length of trench is 8�for the area proposed to be drained into the system (not including the safety factor or the mitigating effect of void space detention volume). Adding a safety factor of 2 seems excessive, given the fact that the size, topography, and soil type of the property makes it impossible for surface runoff to go anywhere else. If the system were found to be performing inadequately over time, a larger one could be easily built in the space available. Any such failure would not cause property damage, would not affect any downstream system, would not affect any other property, and would only cause the temporary inconvenience of surface ponding during an extreme storm event. Even at a length 83 feet, the system provides a safety factor of 1.6 for a 10-year storm, which is as good as most of the rest of the City's systems. The circumstance of this site justify elimination of the safety factor, but at this point I will defer to your final decision. Finally, I was unable to establish with certainty the total area of impervious surface which will ultimately drain into this system. I recommend that if the area is substantially greater than or less than the assumed 7460 square feet, the system be adjusted by 1.15 feet per 100 square feet of impervious surface, multiplied by whatever safety factor is used. This provides a little flexibility to deal with changes. Please call me if you have any questions on this. Sincerely, Craig Campbell, P.E.

Method of Analysis/Length of Roof Downspout Infiltration Trenches The length of trench required is based on the assumption of providing a bottom trench area sized to Infiltrate at a rate equal to the rainfall intensity for the peak 10-minute time step for the 10-year, 24-hour duration design storm event (Time step 460 to 470 minutes, 5.4% of total storm volume P,o, see Table 3.5.1A), and by the maximum infiltration rate Q.) which Is based on the Soil Texture Class by the United States Department of Agriculture (U.S.D.A.) designation system (see Figure 4.5.1E and Table 4.5.1A). The length of trench required is determined by dividing the required infiltration area (AJ by 4 feet (the two -foot trench widith plus one foot on either side for side wail infiltration). A, is computed using the following equation: An _ (0.054 P,oAp)/10 IM 7 ; Where: P,o = 10-Year, 24-hour design storm total precipitation, inches (from Figure 3.5 t 71 IM = the maximum infiltration rate from Table 4.5.1A, min./inch.

It is' recommended that a waiver be granted subject to proper fimcti.oning of the septic system, pending the develo�men.t of property adjoining Second Avenue, �,rherei.n a combined .sewer arrangement would alloy! this residence to make connection. 2) 931 Niain Street (Nelson) This, property can connect .to the sanitary sewer, however, the soil conditions.adjacent to the sewer lateral at )Iain Street indicate potential problems with the -sewer hookup.. n 1.,aiver is recomrended subject to the proper functioning of the septic system, and subject to connecting to sewer if future development of the property. or plumbing; additions occur. 3) 806 Ninth Avenue South (Yeager) This property does not have gravity seurers available and would hest be served through an L.I.D. with gravity sewers to riglith Avenue. 4) 716 Ninth Avenue Soutli (P hxrdock) This property is not served by sanitary sewer. It is recommended that an L.I.D. he formed with.gravity sewers flowing to Eighth Avenue. 5) 929 Car, FZoad (Strickland) There exists a problem related to utility casements and the estate . settlement of business prior to Mr. Strickland's death. It is recommended that a waiver be granted subject to completion of the utility easement, proper functioning of the septic system, and no further developmentof the property until sewer hookups are provided.

It is. recommended that,the'City request them to contact three contractors and provide evidence of the contractor's estimate or refusal. to accomplish the work proposed. Should that evidence indicate the unavailability of a con- tractor to do the wort:, it is recommended that the City proceed with a lateral connection, charging the resident for the actual: cost -of work.

Later, the City installed a lateral from the north but inadvertently.constructed the lateral on private property. Attempts have been made to acquire an easement without results. .This matter needs further study in acquiring an easement from either the owner to the north or south to gain sewer service without removing street -or walk improvements. It is recommended that a waiver be granted until the City can provide a sewer connection point. 9) 20216 76th Avenue hest (11le1cli) This property is not serve(T with a sewer lateral. in 76th Avemie, This sewer connection will require an easement over adjoining property to connect to sewers to the west..

Box 1306 Mukilteo, Wa. 98275 RE: JOHANNSEN REMODEL AT 10727 226TH ST EDMONDS STORM DETENTION REQUIREMENTS Dear Chuck, After reviewing the subject permit application, we have determined that on -site detention will be required because the additional impervious exceeds 2,000 square feet. Based on the drawings submitted, the total additional impervious surface is 6,287 square feet. It has been City policy to include quantities of remodeling when an existing structure is removed and then reconstructed, and to not allow credit for prior impervious surfaces. The existing portion of the house that remains does not have to be included in the detention design, only the additional impervious surfaces. Since the quantity exceeds 5,000 square feet, an engineer must design the detention system using Snohomish County standards of the Y and W method for a 25-year storm and 10-year release. Please submit a drainage plan showing the location of the system and where it will tie into the existing City storm system. If you have any questions, please call me at 771-0220.
