本次整治河道劃分為蓄水區、生態濕地區兩部分,河道規劃按“3段濕地+2段蓄水”景觀治理總布局,自上游開始分別為上游濕地景觀區、上段蓄水區、中段濕地景觀區、下段蓄水區、下游河口濕地景觀區。蓄水區采用中隔墻將河道分為南北兩部分,北側為景觀蓄水區(寬93-123米),南側為泄洪槽(寬70米),共布設8座攔水壩(蓄水區6座橡膠壩,渾水槽2座氣盾壩),形成蓄水總面積61萬平方米(915畝),一次蓄水量108萬立方米。三段濕地總長度3.77千米,總面積71.3萬平方米(1070畝)。

藉河生態環境綜合治理二期工程截至目前完成景觀節點52個;完成步道12.8萬平方米;完成鋪裝9.7萬平方米;栽植喬木6343余株,栽植灌木及花卉約24萬平方米。蓄水區已蓄水,目前項目正在試運行階段。
