ment of no-parking locations (i.e., driveways, fire hydrants, Notes <br />mailboxes) at appropriate intervals to provide the needed gaps. <br />❑ Parking (con't) <br />When determining the number of parking spaces required, <br />consider adjoining land uses and the availability of off-street <br />parking. Parking demand is likely to be less where an adjoining <br />land use is one that will create little or no parking demand (e.g., <br />wetlands, parks, floodplains) or if adjoining development will <br />provide off-street parking adequate for residents and guests. <br />On-street parking demand may be affected by recreational <br />vehicle/equipment if parking of such equipment is allowed. <br />Parking availability will be affected by whether a neighborhood <br />has alleys, if parking is allowed in the alley, or if visitor parking <br />bays are provided in the area. <br />❑ Self-Enforcing Design.... perceptions count! <br />The design of the street should encourage the desired speed, <br />traffic flow, parking, and use of the street. When this is the case, <br />a design is said to be self-enforcing. This means that a driver <br />would discern an implied prohibition against parking by the <br />visual appearance of the street. A self-enforcing design in- <br />tended to reduce speed might, for example, use trees in <br />parkrows or strategically placed curb extensions. <br />• Unless traffic volumes are very low, 21 to 22-foot streets with <br />parking on one side can be problematic for large vehicles. <br />• 21 to 24-foot streets with no on-street parking should not be <br />considered because they invite parking violations. <br />• 26 and 27-foot streets where parking is permitted on one <br />side can result in chronic violations because the street will <br />look wide enough for parking on both sides. <br />❑ Parking Enforcement <br />With adequate parking and proper street design, enforcement <br />should not be a problem. Where parking is prohibited, provide <br />signs that clearly indicate this, even on streets with a self- <br />enforcing design. Enforcement is essential and can be done in <br />a variety of ways. Consider tow zones or using volunteers to <br />write parking tickets. (The City of Hillsboro allows both police <br />and fire personnel to write traffic tickets.) <br />❑ Public and Private Streets <br />Build public and private streets to the same standard. The need <br />for access by emergency and other large vehicles is the same <br />on private streets as for public. (In addition, private streets not <br />built to the same construction standards may end up being a <br />maintenance problem later if the local jurisdiction is forced to <br />assume maintenance because homeowners do not fulfill their <br />responsibilities.) <br />12 <br />102 <br />
