The Local Street Plan staff team has reviewed and discussed your memo, and has considered each recommendation in light of the planning objectives for the street study. Recommendation 2.1 Overall Goals and Guiding Principles for Residential Street Design: DAY recommendations for goals and guiding principles have been incorporated, to some extent, in the proposed planning principles for local street layout and design. The planing principles formulated by the LSP staff team are necessarily much broader than those proposed by the DAC. We found it necessary to address numerous street planning issues that are of no immediate concern to the DAC, such as providing for emergency service vehicles; safety of pedestrians, bicyclists, and other street users; relationship of street design to efficient lot layout; and traffic dispersal. Several of the DAC recommendations, such as those relating to on -site drainage, stormwater quality treatment devices, and design adaptations for various soil types, are specific to stormwater design and not to general street design. Staff feels that it is more appropriate to address them in future stormwater design standards. Fourteen planning principles for the layout and design of local streets have been identified. The planning principles, and the recommendations that were derived from them, support reductions in vehicle - miles -of -travel through proposed street connectivity standards; support reductions in impervious surface area through proposed alternative street design standards (cross section width reductions); support preservation of topographic and other natural futures; and support the potential for alternative stormwater treatment techniques to be used (e.g. grassy swales) through proposals for setback sidewalks, variable width planting strips, and use of inverted curbs on certain low - volume streets. Although every principle suggested by the DAC is not specifically addressed in the draft LSP, staff feels that no proposal in the document conflicts with recommendations outlined in your memo. In fact, several of the draft LSP t recommendations, were developed to accommodate future changes in stormwater treatment approaches.
