4. Shore impact zone • The City does not incorporate the shore impact zone in its shoreland ordinance. • The DNR defines the shore impact zone as an area inland between the OHW and 50 percent of the structure setback (for example, if the structure setback is 50 feet the shore impact zone is the first 25 feet from the lake). The DNR has regulations for the placement of structures, roads, parking, signs, and lighting within the shore impact zone. • Staff recommends adopting the shore impact zone definition and applying the definition where needed. 5. Additional definitions • The DNR has a list of 44 definitions in its shoreland management that cities should include for minimum compliance. The City's regulations do not include or fully include 15 of those definitions in its Zoning Code. Definitions in the DNR ordinance that do not pertain to Arden Hills have been omitted. • Staff recommends adopting the applicable DNR definitions into the City's ordinance. 6. Controlled access lots • Refers to a lot on the lake that is jointly owned by non -lake (non -riparian) lots for shared access to public waters. • The City does not address controlled access lots in its shoreland management ordinance, though there are a few such lots in the City. • The DNR has model regulations for controlled access lots that regulate usage. • Adopting the DNR's model regulations for controlled access lots may be helpful, but new controlled access lots in Arden Hills are unlikely. A number of cities prohibit new controlled access lots. 7. Enhanced variance standards • The City permits variances with the additional requirement that the DNR is notified at least 10 days prior to a hearing or action on the request. • The DNR permits cities to grant variances in line with state statute and requires the 10 day notice before hearing and actions. However, the DNR includes additional provisions for variance review. • Staff recommends adopting the enhanced DNR variance review standards. 8. PUD and subdivisions • The City has limited guidelines for PUDs and lacks specific guidelines for subdivisions in its shoreland management ordinance. While Chapter 11 of the City Code regulates subdivisions, there appears to be no specific ordinances pertaining strictly to shoreland areas. • The DNR has model regulations for subdivisions and PUDs. The DNR's PUD model ordinances may not be needed since they are largely intended for vacant shoreland and other large redevelopments along the shoreland that are unlikely to occur in Arden Hills The commercial -oriented PUD regulations were not included since Arden Hills does not have any commercial land along the shoreline.
