Comprehensive or general plans are long-range documents intended to guide future urban or regional land use, growth, and development. Structured and periodic monitoring and evaluation of plan implementation is important to identifying when plans should be revised or updated based on changed planning assumptions or conditions, but such monitoring is uncommon. In this study we present and illustrate a research-based method to evaluate general plan implementation for a case-study community located in central California. A community survey was combined with participatory mapping to assess continued public approval of key elements of the general plan: 1) residential growth, 2) community development needs, 3) preferred locations for development (spatial), 4) consistency of resident land use preferences with general plan categories (spatial), and 5) areas with the greatest potential for land use conflict (spatial). Over the five-year period following plan adoption, there was relatively little change in general resident preferences for residential growth or the perceived need for new types of urban development, with the exception of affordable housing; however, city approval of three large, mixed-use development projects, while nominally conforming to the plan, generated community conflict based on development scale and location. As a novel plan monitoring and evaluation method, a community survey combined with participatory mapping provides a means to assess consistency with plan assumptions, desired conditions, and goals and can proactively identify the potential for place-based conflicts among various interests to identify optimized community land use outcomes.

综合或总体规划是旨在指导未来城市或区域土地使用、增长和发展的长期文件。计划实施的结构化和定期监测和评估对于确定何时应根据改变的规划假设或条件修改或更新计划很重要，但这种监测并不常见。在这项研究中，我们提出并说明了一种基于研究的方法，用于评估位于加利福尼亚中部的案例研究社区的总体计划实施情况。社区调查与参与式绘图相结合，以评估公众对总体规划关键要素的持续批准：1) 住宅增长，2) 社区发展需求，3) 首选开发地点（空间），4) 居民土地使用偏好的一致性具有总体规划类别（空间），5) 最有可能发生土地使用冲突（空间）的地区。在计划通过后的五年期间，除经济适用房外，一般居民对住宅增长的偏好或对新型城市开发的需求变化相对较小；然而，城市批准的三个大型混合用途开发项目虽然名义上符合规划，但会因开发规模和位置而产生社区冲突。作为一种新颖的规划监测和评估方法，社区调查与参与式制图相结合，提供了一种评估与规划假设、期望条件和目标的一致性的手段，并可以主动识别各种利益之间基于地点的冲突的可能性，从而确定优化的社区土地使用结果。
