There will always be local people that object to new development simply because it's near where they live. As a developer, accepting and understanding these NIMBY motivations can help improve your chances of success.
Some of those that set themselves against new development will do everything they can to stoke opposition, including spreading false information. You need to be 'always on' and ready for rapid rebuttal.
If you work in a 'controversial' sector, or are involved in bringing forwards plans for controversial-yet-critical infrastructure, you're going to be under the microscope at times. A bullet-proof reputation is a must.
