B. OPTIONS FOR MULTIMODAL AND STORMWATER INFRASTRUCTURE ON EXISTING ROADWAYS Through a series of policy decisions, the County is placing a great deal of emphasis on providing a transportation system that encourages alternate modes of travel beside the single-occupant vehicle. Multimodal features like sidewalks and multi-use paths are now considered as part of every pavement management project design. As per the County’s values, staff calculated the costs of constructing missing or substandard multimodal features (based on the currently adopted Unified Land Development Code) and included these costs into the three capital maintenance options. Stormwater facilities required to meet water quality and water quantity minimums on existing roads were also calculated. Table 7: Pavement Capital Maintenance Options with Multimodal and Stormwater Features, below, details the cost of adding multimodal facilities countywide and to only those roadways in the urbanized areas and the cost of adding stormwater quality and quantity features. Staff assumes that it is most efficient to construct multimodal and stormwater facilities at the same time roads are resurfaced, and the estimates listed in Table 8 reflect this assumption.
