Street Design Manual

Design Vehicle - Motor, non-motor vehicles and pedestrians with representative weight, dimensions, and operating characteristics that are used to establish street design controls and standards Development or Development Plan - Any site plan, subdivision, or plot plan Detector - A device used to sense the presence or absence of vehicles or pedestrians in the vicinity of a signalized intersection. Detector Settings - Controls used to affect the operation of a detector. Developer - A site planner, landowner or subdivider. Development/Development Plan - Any site plan, subdivision plan, or plot plan. Driveway Access Point - A point of ingress and egress, or both, which is considered a private driveway. It can be either a residential access point or a commercial driveway access point. Driveway Width - The narrowest width of driveway measured parallel with the edge of street. Facility – Any I nfrastructure on or with which transportation occurs Frontage - The distance along a property(additional sidewalk or shoulder width) required between the pedestrian traveler and adjacent building or environmental features to maintain comfort. Green Interval - The duration of the green indication for a given movement at a signalized intersection. Green stormwater infrastructure (GSI) – Any of a number of practices that, used individually or collectively, contribute to managing, treating, and reducing stormwater runoff from a development or redevelopment site, as close as possible to the runoff’s source, by preserving natural landscape features (such as vegetation, soils, hydrology, and natural processes) and/or by mimicking natural processes through installation and maintenance of structurally engineered devices (such as bioretention cells, bioswales, permeable paving/pavers, green roofs, stormwater street trees, and cisterns). In addition to contributing to stormwater management, GSI practices can enhance site aesthetics, improve air quality, reduce urban heat island impacts, provide shading, create wildlife habitat, reduce energy consumption, reduce infrastructure costs, and increase property values. Internal Capture Trip - A trip made within the confines of a Mixed-use development that does not use the off-site street system. ITE - Institute of Transportation Engineers Level-of-Service (LOS) - A quantitative stratification of a performance measure or measures that represent quality of service, measured on an A – F scale, with LOS A representing the best operating conditions from the traveler’s perspective and LOS F the worst. Loop Street - A street which is designed to discourage through traffic from other areas and both ends of the loop street connect with the same intersecting street.
