As long as your 150 yards from another dwelling, then I think its as simple as having the home owner filling out the riparian landowner application, it may cost $60 or so for a 3 year deal. This land gets marked off so nobody can pick it in the blind lottery. Let me know if you need help shooting any birds there too
You have to have 250 yards of shoreline or permission from your neighbors IIRC
The verbage - - -
"Riparian landowners wishing to establish an offshore blind must either own at least 250 yards of continuous shoreline or they must have written permission from adjoining neighbors to total at least 250 yards of continuous shoreline, except that a riparian landowner who does not own or have written permission for shoreline totaling at least 250 yards may still establish a blind site (but not a stationary blind) if no other shoreline is licensed within 125 yards of the blind site.
If an applicant submits an application and the location of the blind fails to meet the 125-yard test, the shoreline will still be licensed only. There are some parts of the state in Baltimore and Kent Counties where no licensing may take place (see Appendix 2 for area descriptions"
