The Horsham Local Plan Water Neutrality Technical Note is an extract of Appendix E of the Habitats Regulations Assessment.  It was commissioned as part of our wider Habitats Regulations Assessement which already forms part of our Evidence Base.  It therefore did not need to be repeated as part of the Part A work carried out by Chichester and Crawley.
