34. When access to or within a structure or an area is unduly difficult bacause oF secured openings or where immediate access is necessary for life-saving or fire fighting purposes, the Fire Department may recommend or require a key box to be installed in an accessible location. A rapid entry system may also be desirable in order to avoid unnecessary damage while making entry to any building during an emergency situation. 35. Construction activities on the site must be in confortnance with the City of Everett Noise Ordinance, EMC Chapter 20.08. This preGudes the operation of loud construction equipment between the hours of ten p.m. and seven a.m. on weekdays and six p.m. and eight a.m. on Saturdays, Sundays, and stale- recognized holidays. 36. The proposal must also comply with all other City Code and Ordinance requirements not specifically set forth herein. General Information The proposed stotm drainage system appears to collect the entire site's stormwater rur,ofi and route it to the detention pond and biofiltration swale in the eastem portion of the site. The storm drainage will have to be modified to direct water to the wetlands (see Condition 14 of the MDNS). The drainage plan may need to direct rookop runoff to the wetland areas. 2. The proposed swale area may not meet City standards for 3H:1V side slopes. Where a swale is located adjacent to a building, a minimum of ten feet of essentially flat ground must ba provided beriveen the building and tho top of the swale, unless otherwise approved by the Fire Marshal. The engineer should coordinate the design of the swale with the Public Works Oepartment, so that it meets City Standards. The biofiltrstion swale must be consVucted and planted per City standards, and not according to the details in the mitigation plans and other documents submitted with the SEPA application. Adequate detail must be shown on the detailed plans to enable the City to determine that the location of the proposed vegetated swale is feasible, including the proposed finished floor elevations of buildings adjacent to the swale and proposed grading contours. 3. Discharge of water to wetland should mimic the natural discharge as much as is feasible. Where point source discharges do not occur under undevelaped conditions, such discharges should be avoided. Techniques that result in dispersed discharge, such as dispersion trenches or buried peRorated pipe located at wetland buHer edges, can be used to mimic naturally occurring sheet flow into wetlands. 4. Condition 18 of the MDNS requires that stortnwater be treated through vegetated swaies and oilMrater separators or through wetponds prior to discharge from the site or into streams or wetlands. To keep hydrocarbons, pesticides, nutrient and sediment pollution from the wetlands, the grading plan should provide for a small bertn around all of the wetlands to prevent flow into them. This is particularly critical on the south side of Phase I, because the slope is essentially flat (elevation 534) across lhe westem half of the development. Additionally, the east side of one of the Phase I buildings slopes directly into the
