As you're developing your path network plans, you'll need to get support from a range of people. That might be because you need them to provide funding or so you can get any necessary permissions in place or just so that more people are aware of what's taking place.
You should make sure you stay in contact with your local authority access officer (and the National Park Authority if you're within one of the National Park areas). Many of the people within these authorities will be able to help you develop your ideas, perhaps by providing cash but certainly by providing support and practical assistance. It's best to keep them informed of your activities and plans rather than dropping them out of the blue.
Getting support from organisations like these can be time-consuming, but in the long run it will help your plans take shape. This factsheet provides more information on who and how you should lobby to get support for your path group and your future projects.
