(Strong concern about this issue.) • Follow Staff (Environmental Specialist) recommendations: Infiltration areas proposed on site should have the City native seed specification used. Native seed should be applied at the same time as erosion control vegetation seed is applied. There should be no importing or exporting of soil form the site with out City approval. All BMPS for erosion control and compaction control should be followed. Soils should be restored to pre - grading compaction densities. A boulevard tree should be provided for each lot frontage. The tree inventory should indicate genus and species with size. Several recommendations have been included in the conditions of approval, below. Notes on the grading plan include tilling the infiltration basin to 6" prior to seeding, which addresses the
