central portions of the site, respectively. The west basin will have two cells. The north cell is proposed to be lined to maintain a permanent water pool that will be landscaped and used as a site amenity. The south cell of the west basin and the east basin will allow infiltration of storm water in the granular soils. The west basin will have an emergency storm sewer outlet to a natural wooded depression in the southeast corner of the site. This will also function as an infiltrating basin. The east basin will have an emergency outlet to the Highway 169 ditch. The storm water basins, as shown, will provide the required volume for two back-to-back 100-year storms. VII. SITE GRADING The majority of the site is relatively flat, which is conducive for commercial development with large buildings and parking areas. The most extensive grading will be in the south portion of the site, which had not previously been mined and the excavation to construct the proposed stormwater basins. VIII. WETLAND ALTERATION An application has been made requesting exemption as incidental wetlands for the two small wetlands existing on the site. No wetland mitigation is proposed. IX. TREE PRESERVATION AND LANDSCAPING The existing trees in the northwest corner of the site would be removed for the proposed street realignment. The development plan shows preservation of about half of the wooded area in the south portion of the site. This would provide a buffer to the adjacent residential lots. New trees are proposed in the street boulevard and islands in the parking areas. Extensive plantings in conjunction with berming are proposed along the west side of the development to provide screening. The landscaping would meet or exceed the City ordinance requirement. X. STREETS AND ACCESS Access to the proposed commercial lots would be provided by proposed Holt Street NW, which would serve as a frontage road along Highway 169. This is a logical extension north of 194th Avenue NW at the south side. Holt.Street is proposed as a 44-foot wide street with two northbound lanes and one southbound and, and also with additional right-turn lanes at the two entrances to the project. The second northbound lane provides a by-pass lane around left turning vehicles at the entrances and a right turn lane at entrances to the north lot and at 197th Avenue NW. On the north side, realignment of 197th Avenue is proposed to eliminate the jog at Irving Street. Irving Street would also be 4 U:\MDC\MDC0301\Documentation~A - Architects~A1 Architects File (incl.
