and a cover, the cover set in the frame, the cover extending beyond the frame on at least one side an amount sufficient to carry stormwater runoff to a stormwater management practice system. ### Claim 15 (depends on 14) The stormwater diversion and overflow device of claim 14, wherein the frame comprises an angle member having a first portion extending less than 360 degrees around a perimeter of the frame, defining an opening through which fluid can flow. ### Claim 16 (depends on 15) The stormwater diversion and overflow device of claim 15, wherein the first portion is aligned vertically when the frame is installed. ### Claim 17 (depends on 16) The stormwater diversion and overflow device of claim 16, wherein the angle member comprises a second portion, the second portion being aligned horizontally when the frame is installed, the second portion connected perpendicularly to the first portion. ### Claim 18 (depends on 16) The stormwater diversion and overflow device of claim 16, wherein the second portion extends 360 degrees around the perimeter of the frame. ### Claim 19 (depends on 17) The stormwater diversion and overflow device of claim 17, wherein the second portion comprises an extension on each of four sides of the perimeter of the frame, each extension being perpendicular to each adjacent extension. ### Claim 20 (depends on 15) The stormwater diversion and overflow device of claim 15, wherein the first portion extends on three sides of the perimeter of the frame, defining the opening on the fourth side of the perimeter of the frame. ### Claim 21 (depends on 14) The stormwater diversion and overflow device of claim 14, wherein the cover at least partially defines an opening between the cover and the frame, the opening configured to allow stormwater to pass from the stormwater management practice system to a catch basin. ### Claim 22 (depends on 14) The stormwater diversion and overflow device of claim 14, wherein the device further comprises a grate set in the frame adjacent to the cover, the grate further comprising: a vertical portion comprising at least a portion of a perimeter of the grate; and a plurality of parallel slats having a first end and a second end, the parallel slats extending from the vertical portion at the first end, at least one of the slats remaining free and unconnected at the second end. ### Claim 23 (depends on 14) The stormwater diversion and overflow device of claim 14, wherein the grate comprises: a vertical portion comprising at least a portion of a perimeter of the grate, the vertical portion defining an opening in the perimeter of the grate through which fluid can flow. ### Claim 24 (depends on 14) A catch basin diversion system, the system comprising: the stormwater diversion and overflow device recited in claim 14, the stormwater diversion and overflow device being installed in a street; a catch basin under the street; and an alternative stormwater management practice positioned adjacent to and off the street. ### Claim 25 A method of installing a stormwater diversion and overflow device, wherein a frame and grate functioning as an opening for stormwater runoff to enter a catch basin is replaced with the stormwater diversion and overflow device to divert stormwater runoff to an alternative stormwater management practice device and redirect excess stormwater runoff exceeding the capacity of the alternative stormwater management practice device back to the catch basin, the stormwater diversion and overflow device comprising: a diversion and overflow frame; and a diversion and overflow cover, the frame comprising a perimeter member having a first portion extending less than 360 degrees around a perimeter of the frame, defining an opening through which fluid can flow, the cover extending beyond the frame on at least one side an amount sufficient o carry stormwater runoff to a storm water management practice system, the cover at least partially defining an opening between the cover and the frame, the opening configured to allow stormwater to pass from the stormwater management practice system to the catch basin. ### Claim 26 (depends on 25) The method of claim 25, wherein the stormwater diversion and overflow device further comprises an overflow grate, the overflow grate comprising: a vertical portion which comprises at least a portion of a perimeter of the grate; and at least one slat extending from a first end connected to the vertical portion to a second, unconnected end, the vertical portion at least partially defining an opening in the perimeter of the grate through which fluid can flow.
