0 3. Formula for Detemumlig Number of Peak Hour/Peak Season/Peak Direction Trips Generated: Number of Units X P.M. Peak Hour Rate X Inbound P.M. Percentage X Inbound -Northbound Percentage (227 X 1.01 X.65 X .53 m 79) (trip disvibution based on a Modified Gravity Model) 4. Traffic Capacity on this segment of 666 Avenue, at a Level of Service "D": 1,230 peak hour/peak season/peak direction trips 5. Total Segment Demand (existing volume + vested volume) on this segment of 666 Avenue: 323 peak hour/peak season/peak direction trips To determine the number of trips that would be generated by the most intense use of the subject property under the proposed land use designation, the total number of units allowed under the proposed amendment (227) was multiplied by rMs factor of 1.01 tripshmit to determine the total number of trips generated (230). Of these trips, 65% (150) will be inbound, and 35% (80) will be outbound. Of the inbound trips, 53% or 79 will be northbound. Using a modified gravity model and a hand assignment, the trips generated by the proposed use were then assigned to impacted roads on the network. Capacities for all roadway segments in the county are updated annually. Available opacity is the total opacity less existing and committed (vested) traffic volumes; this is updated daily based upon vesting associated with project approvals. The roadway segment that would be most impacted by development on the subject property is 666 Avenue, from 266 Street to 41° Street. The traffic opacity for that segment of 666 Avenue is 1,230 trips, while the Total Segment Demand (existing traffic volume + vested traffic volume) is 323 trips. The additional 79 trips associated with the most intense us allowed under the proposed land use designation would increase the total trips for that segment of 666 Avenue to approximately 402. Based on the above analysis, staff determined that 666 Avenue and all other impacted roads can accommodate the additional trips without decreasing their existing levels of service. There is also sufficient water and wastewater pleat capacity to accommodate the proposed land use designation. Based on the most intense use allowed under the proposed land use designation, development of dm property will have a water consumption and a wastewater generation rate of 230 Equivalent Residential Units (EM), or 57,500 gallons/day. This is based on a level of service of 250 gallons/ERU/day. Although neither water nor wastewater lines currently extend to it, the site is looted within the north county water plant and west county wastewater treatment plant service areas, respectively. The north county water plant, which is expected to be completed by the summer of 1998, will have a opacity of 2,000,000 gallons/day and will be able to accommodate the additional demand generated by development of the subject property under the proposed land use designation. Similarly, the west county wastewater treatment plant currently has a remaining opacity of approximately 148,000 gallons/day and can accommodate the additional wastewater generated by development of the subject property under the proposed land use designation. With respect to solid waste disposal, the county's adopted level of service standard for landfill opacity is 237 cubic yards/person/year. With the county's average of approximately 2.3 personshinit, a 230 unit residential development would be anticipated to house approximately 529 people (23 X 230). For the subject request to meet the county's adopted level of service standard of 237 cubic yards4xnoa/year, the landfill must have enough opacity to accommodate approximately 1,254 (529 X 237) cubic yards/year. A review of the solid waste capacity for the active segment of the county landfill indicates the availability of more than 840,000 cubic yards. The active segment of the landfill has a 1 year capacity, and the landfill has expansion opacity beyond 2010. Based on the analysis, staff determined that the county IandfiII can accommodate the additional solid waste generated by the site under the proposed land use designation. The stomrwater management impacts of development are reviewed in detail during the development approval process. All developments are reviewed for compliance with county stormwater regulations which require on-site retention, mon of floodplain storage and minimumm finished floor elevations. In addition, development proposals must meet the discharge requirements of the county Storrawater Management Ordinance. Since the site is looted within the M-1 Ihainage Basin and the Indian River Farms Water Control District (1RFWCD), development on the property will be prohibited from discharging any runoff in excess of two inches in a twenty-four hour period, which is the approved IRFWCD discharge rate. In this case, the minimuen floor elevation level of service standards do not apply, since the property does not lie within a floodplain. However, both the on-site retention and discharge standards apply. MARCH 10, 1998
