Little space on each lot for pedestrian entrances, street trees or front yard landscaping Higher Density Concerns • Sidewalks interrupted by wide driveways Higher Density Concerns Wide driveways + narrow lots = Loss of on -street parking Reducing Community Resistance • How private space meets the public space is important • If higher density housing is planned in a manner that respects the public spaces as well as the private spaces, people tend not to notice that it is higher density. • Comprehensive Plan goals- Compact, walkable neighborhoods with a diversity of housing types Comprehensive Plan Goals • Neighborhoods with residential character • Homes that respect neighborhood streets Mr.; " e jKl ✓rti w • Streets that are pleasant for walking, biking and visiting • Room for on -street parking Its not just about reducing costs, its also, about ensuring long term value, Housing: Reducing Costs & Adding Value • Increase opportunities for lower cost housing by allowing higher density housing • Strategies to reduce community resistance to higher density housing. Adopt standards to ensure high quality neighborhoods that will stand the test of time. 0 Two -Pronged Approach Planned Development Overlay • To develop higher density housing, such as townhouses and small lot single family, developers previously had to apply for a planned development overlay rezoning. • Plans are subject to review by the public at rezoning hearings before the Planning and Zoning Commission and the City Council. a Planned Development Process Cons o Developer incurs design and engineering costs upfront without assurance that the planned development will be approved. o Process sometimes lengthier than standard rezoning and subdivision • Pros o Give and take of the up- front design process often results in a higher quality development o Master planned community - buildings, streets, and open space are designed to fit the site. o Plan becomes the zoning. Community is assured of the result. Possible Solution • Allow compact development by right, with no planned development rezoning required. However.... • As a part of the streamlined approval process, establish standards in the Code to ensure the resulting development will maintain the same residential environment enjoyed by lower density neighborhoods. • The same types of standards often negotiated through the planned development process. Increase Opportunitie for lower cost housing, • Allow compact development in all SF zones through bonus density provisions - allow reduction in lot size and width No planned development rezoning required process Reduce Community Resistance -ME • Establish new standards to ensure that garages and driveways do not dominate the smaller, narrower lots. Alleys required for narrowest lots.
