All developments shall be reviewed for applicability of the stormwater management provisions of Chapter 162 of the Danville Code of Ordinances. If the provisions of Chapter 162 are deemed applicable to the development, changes to the drainage and runoff of surface water shall be assessed as part of the site plan review of the development. If storm water runoff related to any change to land may affect drainage systems within the City, the developer or land owner may be asked to provide, at the developer's expense, a certification by a licensed design professional retained by the developer or owner, stating that to the best of their knowledge and belief, the drainage of surface waters affecting the City will not be changed by the construction or development of the proposed use, building or structure. If surface water runoff will be increased as a result of the development, or if the impervious area of the site increases, adequate provision shall be made on the subject lot for the collection and diversion of any excess runoff as is required by Chapter 162 of the Danville Code of Ordinances. Such excess runoff shall not be deposited on the property of adjoining land owners or onto City property in such concentrations as may cause damage to these other properties.
