Permeable grass pavers: Encroachment into CWQZ but outside 50-ft of channel Centerline. Replaces existing Greenhouse and material storage/equipment parking. If Not Granted: Loss of 4 Units 2. 3. Permeable grass pavers: Encroachment into CWQZ with portion within 50-ft of channel Centerline. Replaces existing impervious cover/home.

Overhang allows commercial space to realize standard bay depths, Restricted to the west due to Tree canopies. 3. If Not Granted: Loss of 4,500sf of leasable space 14 Summary of Proposed Encroachments Encroachment and Result: 1.
