All existing water lines and proposed services were shown on the plans. We have emboldened the line <br /> weights for these so they stand out. <br /> IWe have shown the proposed fire hydrant behind the sidewalk as suggested. It must be noted that our <br /> hydraulic analysis report for the utilities services sizing shows that the existing hydrant locations are <br /> within reach of this site in hose-lay consistent with the City design criteria (but the fire marshal insists on <br /> 200-ft driving distance),while the proposed new building addition is required by the fire marshal to have <br /> a fire sprinkler system. <br /> The note specifying the City to install the fire hydrant has been added as stated; see sheet C-4. <br /> 'The location of the existing water meter serving the south neighboring building was shown on the plans <br /> as located by the surveyor. We have added this-water service extension to the plans;it is not in conflict <br /> with the proposed building in accordance with the utility locator prior to the survey. We have added a <br /> caution note to locate this service line on the ground, and then by hand digging potholes,just prior to <br /> any construction activity under this permit. <br /> A sanitary sewer service cleanout has been added,with invert elevations specified for all cleanouts. <br /> V/Any discrepancies have been corrected. <br /> accordance with a telephone conference with Arnie Roshak of Everett Public Works,we carefully <br /> jIn <br /> reconsidered the separation of sewer and stormwater from this site with the conclusion that we were <br /> correct in our planning in keeping with the ultimate separation of the combined sewer service for this area <br /> and not adding to it. Therefore,we will keep the filter swale and storm drainage extension as shown on <br /> our plans in keeping with clean stormwater goals. <br /> 'The MDNS determination and stipulations for this site are noted and followed in our construction <br /> Tans. <br /> . In accordance with our site analysis as presented in the Stormwater Questionnaire, the total of the new <br /> plus replaced impervious surfaces for this project is less than 5000-sf, as summarized below; and <br /> therefore,in accordance with the flow chart in Fig 2.2 of 210 Stormwater Management Manual,no <br /> additional requirements apply. <br /> Total of proposed hard surfaces (paved parking lot,new addition rooftop) 7,106 sf <br /> Total of existing hard surfaces to be removed or replaced: 1483 sf <br /> Total net new hard surfaces: 4,623 sf <br /> /As stated above, detention should not be required for this project given its very small size and miniscule <br /> ipact on the combined sewer system level of service, as recently discussed with Arnie Roshak. <br /> ../ As stated in our geologic assessment for this site in the Stormwater Questionnaire, the subsurface <br /> conditions offer some capacity for infiltration, although the proposed stormdrain extension as shown <br /> CnT o <br />
