all facilities must be designed using one of the three methodologies outlined in the Manual if all of the following requirements are met: (1) the proposed alternative design will achieve equal, or superior, results for reducing pollution, maintainability and safety and the proposed siting does not adversely affect structures or other properties; (2) the applicant's written description of the proposed alternative design has been reviewed and approved by the City Engineer; (3) the applicant has submitted a method and schedule for monitoring the effectiveness of the proposed design; and, (4) the applicant has submitted a signed statement that the applicant will replace the alternative facility if the facility does not function as proposed. 4. An applicant can seek an adjustment to the requirement that the applicant demonstrate that peak rates of flow delivered to an existing open waterway at a point above 500 feet will not increase during storms larger than the water quality design storm and smaller than the flood control design storm as a result of the subject development if the proposed flow control facility will control flow rates as much as possible and one of the following applies: (1) the area generating untreated runoff is less than 500 square feet of impervious surface and is isolated from the flow control facility; (2) the area generating runoff is less than 500 square feet of impervious surface and it is not technically feasible to drain the untreated runoff to the pollution reduction facility; (3) constructing pollution reduction facilities to treat the runoff from the area at issue would require removal of trees or damage other natural resources; or, (4) the area generating untreated runoff is less than 500 square feet of impervious surface and limited access to the area would prevent regular maintenance of the flow control facility. 5. An applicant can seek an adjustment to the requirement that all flow control facilities must be selected from and sited, designed and constructed according to the Stormwater Management Manual if all of the following requirements are met: (1) the proposed alternative design will achieve equal, or superior, results for reducing pollution, maintainability and safety and the proposed siting does not adversely affect structures or other properties; (2) the applicant's written description of the proposed alternative design has been reviewed and approved by the City Engineer; (3) the applicant has submitted a method and schedule for monitoring the effectiveness of the proposed design; and, (4) the applicant has submitted a signed statement that the applicant will replace the alternative facility if the facility does not function as proposed. 6. An applicant can seek an adjustment to the requirement that all oil control facilities be sited, designed and constructed according to the Stormwater Management Manual if the applicant can demonstrate that the selected oil control facility will achieve the same result as those listed in the Manual. 7. An applicant can seek an adjustment to the requirement that all source controls be sited, designed and constructed according to the Stormwater Management Manual if the applicant can demonstrate that the selected source control will achieve the same result as those listed in the Manual. Considering the above-listed provisions in the stormwater development standards, the application of Exhibit A to Ordinance No. 20369 Findings of Consistency
