Procedural items are still needed for the construction of a new County Regulated drainage system: Petition for regulated drain subdivision, subdivision outlet connection permit, subdivision nonenforcement request, engineer's estimate and all associated bonds for 120% of construction cost. 2. Any private tile drains discovered during construction will need to be tied into the regulated drain system. 3.

For guidance on how to do this, you may contact Brian Rayl at 317-776-8495 or survey orfhamiltoncoun .in.wv- 4. Several Common Areas are designated as Landscaping Easements as well as Drainage Easements while having stormwater infrastructure running through them. No Common Areas with stormwater infrastructure can be designated as a variable landscaping easement as well as drainage easement. Please revise development plans and secondary plat accordingly. 5. Several common areas show trees being planted within 15 feet of the centerline of a stormwater drain. Please revise the landscaping plan to where no shade or evergreen tree is located within 15 feet of the centerline of a drain that is to be regulated.
