Plants show <br />growth consistent with each species, planting well is free of weeds and other <br />plants. Plant exhibits good health. <br />Plants exhibiting poor health or disease will be identified as not surviving and will be <br />required to be replaced. <br />As determined by the City, survival rates may be measured using an area sampling <br />method. To determine the rate of survival, the City and Contractor shall select <br />representative sample areas of each species planfied and at varied locations throughout <br />the project site. These will be determined after the original planting. The sample area will <br />be delineated with %"metal rods supplied by the Gontractor so as to re-establish corners <br />later. The sampling areas may be the same for different species and all sampling areas <br />taken togethershall represent no less than 20°/° of each species planted; Each sample <br />area will be counted after initial planting and then again in September 2009 and 2014. <br />This must occur prior to the dropping of leaves on. any plants. Each plant species will be <br />counted separately at each sample area and documented. Sample area totals of <br />individual plant species counted as healthy, surviving plants shall be documented. The <br />sum of these totals shall be compared to the original planting total within the sample area <br />and a survival rate established per species based on this. The survival rate for plant <br />success will be 80°/°. <br />Example: <br />Total cottonwood trees planted on project. = 300 <br />SO°/° survival rate required by contract = 240 <br />Original count of all sample areas after initial planting of cottonwood trees = 80 <br />trees. <br />Fall count of surviving cottonwood trees after initial planting = 60 trees. <br />First year survival rate = l5%. <br />First year warrantee replacement X300 x ~$0°/°-75°/°~~ = ~ 5 cottonwood trees <br />Replacement planting will first replace plants in the sample areas on a one for one <br />basis, the balance located at the direction of the Gity. <br />The same process is repeated the following year. <br />The Contractor shall plant new and healthy plants of the original plant species each <br />year of the establishment period and shall plant the number of plants necessary to <br />achieve 80°/° survival rate. Replacement plants shall meet the plant quality <br />standards specified in Section 2.6 above and. shall be planted as specified in section <br />2.10 above. Once planted, replacement plants shall be considered original plantings <br />forthe purpose of warranty. Should a species not be available orfor other reasons, <br />the City may request or approve a request to use another plant species. The <br />Contractor is required to submit this request 14 days prior to planting. Substitution of <br />species will not change bid item value. <br />The use of representative sample areas is intended to efficiently measure planting <br />success. If work within the sample areas does not accurately reflect the condition of <br />the entire planting site, the City reserves the right to reject all establishment work. <br />
