City of Arden Hills City Council Meeting for January 9, 2017 Page 8 of 17 Development of the site as proposed in the Master PUD requires extensive tree removal. The applicant has stated their intent to redevelop the site in such a way that preserves as many high quality trees as possible, knowing that many of the significant trees will have to be removed in order for the property to accommodate the new development. Based on the proposed tree removal for the project, the City’s Tree Preservation Ordinance requires 458 caliper inches of tree plantings. At this time, the applicant is proposing 45 caliper inches, or 18 replacement trees. Phase 1 Cal. Inches Trees Existing Significant Trees 2,228 142 10% Permitted Removal 223 14.2 Proposed Removal 1,138 72 Total Trees Preserved 1090 70 Replacement Trees Required* 458 183 (@ 2.5 cal. inches) Replacement Trees Proposed 45 18 (@ 2.5 cal. inches) * Replacement trees are calculated by subtracting the ten percent permitted removal from the proposed removal and dividing by two. A variety of trees species and tree sizes are proposed including White Oak, Red Oak, Red Maple and Black Cherry. In exchange for flexibility in this requirement, the City is reques ting a fee in lieu of tree replacement. There are only 45 caliper inches proposed in replacement trees for Phase 1, while 458 caliper inches are required. At retail price, the replacement trees would cost about $100 per caliper inch. The PUD allows for flexibility in the City Code requirements for tree preservation. Staff recommends that the fee-in-lieu is reduced by a third because the City would likely buy such a large number of trees at a wholesale price and to recommend reducing the by an additional third because of the buildings meeting the architectural requirements of the B-2 zoning district. The remaining third would equate to a fee-in-lieu amount of $13,767. Staff notes that any trees to be removed in future phases will not be allowed the 10% permitted removal and must pay a fee-in-lieu of $33.33 for each caliper inch required to be replaced (one caliper inch replaced per two caliper inches removed). B. Tree Plantings – Meets Requirements Tree planting requirements for new development in the I-1 Limited Industrial district are determined by dividing the gross square footage of all floors of the building by three hundred twenty (320). Tree planting requirements have been determined for Phase 1. Additional tree plantings will be required as part of the multi-tenant commercial and daycare development in future phases.
