species or sterile introduced grass .:pecies, such as wheat thatch, should be used to minimize long-tortn competition with native forbs and grasses (rather than ryegrass). 5. The Phase I planting should use tho random triangular planting pattem recommended in the Phase II planting plan in order to minimize an unnatural ordered appearance to the buHer. B. Phase II: 1. A 75 foot buHer must be provided adjacent to the southem wetland on that site (a riparian wetland) per Section 37.104 of the Zoning Code, or a wetland buffer modification must be obtained tnrough Review Process IIC. (Note: a maximum buffer reduction of 5096 is pertnitted through Review Process IIC. The buHer must be from the edge of the� wetland, inGuding the expanded wetland area. The buHer shown on the site plan is less than 37-1/2 feet in some places.) A 25 foot buffer is required adjacent to Silver Lake Creek. The required vegetated swale length must be conshucted outside of the buNers. 2. Final plans must show the location of Silver Lake Creek on the site and to the east of Phese II. The Applicant must modify the Silver Creek sVeam cortidor by reshaping the west stream bank adjacent to the proposed swale to obtain a 3:1 slope from present top-of-bank to 25 feet back from top�of-bank. This reshaped bank must be replanted with native sVeamside vegetation. 4. Red osier dogwood must be planted along with the willow in the ettpanded porlion of the south boundary wetland. The red osier dogwood and willow must be planted at 2(eet on center. 5. To minimize erosion in Geared an+as, either appropriate native species or sterile introduced grass species, such as wheat thatch, should be used to minimize long-tertn competition with native forbs and grasses (rather than ryegrass). C. Phase 1 and Phase II: 1. With elimination of the degraded riparian cortidor connecting the Phase II wetland with wetlend 2 and eliminaGon of the native vegetation connecting wetlands 1 and 2, animal migration will be significantly impaded. The project needs to maintain weUand comdors by establishiny environmentally sensitive habitat areas along the southem haN of the westem boundary of Phase I from weUand 2, along lhe westem haH of the southem boundary, and along the southem half of the eastem boundary. "�'hese areas must be a minimum of 10 feet wide, with 15 feet recommended, and they must be planted with vegetetion approved by the Planning Department. 2. Fencing must be provided at the edge of the buifers for all weUands and the sVeam, and along the edpe of the wildlife cortidor� required in condition a. above. Fenciny oi the central wetland must be a split rail EXNIIII.�_ P L o��
