SITE ADDRESS <br />4715 WEST VIEW DRIVE <br />HOMEOWNER <br />VANCE & ALEAS AESCHLEMAN <br />4715 WEST VIEW DRIVE, EVERETT, <br />98203 <br />FLOW CONTROL PLAN <br />Project site falls within the limits of combiner <br />sewer area. Addition adds more than 200 SF <br />of impervious surface requiring construction <br />implementation of flow control BMP's to <br />achieve Flow control performance standards <br />1. Flow Control plan developed following <br />the Snohomish County Drainage Manua <br />Volume III - Hydrologic Analysis and <br />Flow Control BMP's Section 3.1.2 <br />Downspout Dispersion Systems (BMP <br />T5.1 OB) splash blocks <br />2. Vegetation flowpath meets minimum <br />50ILF from discharge point to the <br />downstream property line (west propert <br />line or any Other Conflicting surface) MAf <br />3.2 EA splash blocks provided for new RIM <br />addition, each handling 403 SF of run 262 <br />water runoff (< 701 <br />4. Splash blocks utilizing crushed rock 2' <br />wide by 3' long by 6" deep (Figure 3.5 <br />Splash Block Dispersion). <br />5. Proposed addition and splash block is 50' <br />from property line and 70' from City <br />street. <br />6. Additional impervious water will not tie <br />into or reach the combined sto"water <br />sewer system <br />7. No erosion or flooding of downstream <br />properties <br />8. No landslide hazards present <br />9.
