Cities throughout the world are experimenting with Low Impact Development (LID) strategies to replace ecosystem services degraded by urbanization. Stormwater management may need both centralized/publicly-managed infrastructure and decentralized provision by landowners. For landowners to participate in these programs they will need some latitude in the choice of techniques and siting. However, these landowner choices will affect the bundle of ecosystem services provided (such as infiltration, aesthetics, pollution filtering, and others) as well as their spatial distribution. We studied the Santa Monica (CA) stormwater regulations that require stormwater management on a large portion of development and redevelopment but allow a significant degree of landowner choice over the method of rainwater management. We use a novel dataset to investigate both the cost of rainwater best management practices (BMPs) and landowner choice of rainwater BMP. We find strong evidence of economies of scale in capital costs for the smaller size ranges of the BMPs in our data, and that property factors such as land use and overall redevelopment project cost affect rainwater BMP costs. In addition, our results are consistent with the hypothesis that property factors such as building density and land value are important factors in the landowner’s choice of rainwater management option.

世界各地的城市都在试验低影响发展（LID）策略，以取代因城市化而退化的生态系统服务。雨水管理可能既需要集中/公共管理的基础设施，又需要土地所有者的分散供应。要让土地所有者参与这些计划，他们将需要在选择技术和选址方面有一定的自由度。但是，这些土地所有者的选择将影响所提供的生态系统服务捆绑（例如渗透，美学，污染过滤等）及其空间分布。我们研究了圣塔莫尼卡（CA）雨水法规，该法规要求在大部分开发和再开发中进行雨水管理，但允许大范围的土地所有者选择雨水管理方法。我们使用一个新颖的数据集来调查雨水最佳管理实践（BMP）的成本和雨水BMP的土地所有者选择。在我们的数据中，我们发现了BMP较小规模范围的资本成本规模经济的有力证据，并且土地使用和总体重建项目成本等财产因素影响雨水BMP成本。此外，我们的结果与以下假设相一致：建筑物密度和土地价值等属性因素是土地所有者选择雨水管理方案的重要因素。土地使用和整体重建项目成本等财产因素会影响雨水的BMP成本。此外，我们的结果与以下假设相一致：建筑物密度和土地价值等属性因素是土地所有者选择雨水管理方案的重要因素。土地使用和整体重建项目成本等财产因素会影响雨水的BMP成本。此外，我们的结果与以下假设相一致：建筑物密度和土地价值等属性因素是土地所有者选择雨水管理方案的重要因素。
