Land-use change can significantly affect the provision of ecosystem services. On a local scale, zoning laws and other land-use regulations are commonly used to influence land-use change, but their effectiveness is often unclear. We evaluate the effectiveness of local land-use planning in concentrating development and minimizing impacts in riparian areas. We use spatially-explicit land cover data from the USGS Land Cover Trends project to measure development and disturbance rates before and after implementation of Oregon's land-use planning system. We apply a difference-in-difference estimator to address the problem of non-random assignment of regulations on the landscape. We find that land-use laws in Oregon have concentrated development inside of UGBs and lowered development rates in riparian areas. However, disturbance in riparian areas has increased inside of UGBs. Overall, our findings suggest that local land-use planning can be an effective tool for promoting the provision of non-market ecosystem services.
