These requirements may include well-drained soils, acid soils, or other conditions. It is the developer’s responsibility to denote in the development plan or subdivision plat what measures, if any, have been taken to survey existing conditions to ensure compatibility with each planting species proposed, and what modifications, if any, are proposed to enhance existing conditions to insure compatibility with each proposed species.
(3) All crippled, deformed and physically damaged trees, regardless of species, shall be removed and replaced if an inspection by the city indicates that recovery and normal development cannot be expected.
