Systems, apparatus, and methods for maintenance of stormwater management systems

1. A flared end ramp for managing a flow of material into a stormwater chamber, the flared end ramp comprising:

an inlet end configured for connection with a pipe or a drainage structure;

an outlet end configured for placement within the stormwater chamber; and

an inclined surface extending between the inlet end and the outlet end of the flared end ramp and configured to deliver material from the pipe into the stormwater chamber; and

wherein the inclined surface includes at least one drainage groove extending between the inlet end of the flared end ramp and the outlet end of the flared end ramp configured to promote the flow of material towards the stormwater chamber; and

wherein the at least one drainage groove includes:

a first drainage groove extending along a midline of the inclined surface or being angled laterally outward from the inlet end toward the outlet end; and

a second drainage groove angled laterally outward from the inlet end toward the outlet end.

2. The flared end ramp of claim 1 , further comprising:

at least one support foot configured to support the flared end ramp, the at least one support foot being located at the outlet end of the flared end ramp and extending laterally from the flared end ramp.

3. The flared end ramp of claim 2 , wherein the flared end ramp includes a support foot extending laterally between a first side of the outlet end and a second side of the outlet end, the support foot forming the widest portion of the flared end ramp.

4. The flared end ramp of claim 2 , wherein the at least one support foot is configured to secure the flared end ramp relative to the stormwater chamber.

5. The flared end ramp of claim 1 , wherein the stormwater chamber is an open-bottom chamber or a cylindrical pipe.

6. The flared end ramp of claim 1 further comprising a side wall of the flared end ramp, the side wall having a semi-circular profile or an annular profile at the inlet end.

7. The flared end ramp of claim 1 , wherein the at least one drainage groove is configured to promote runoff flow along a midline of the flared end ramp and into the center of the stormwater chamber.

8. The flared end ramp of claim 1 , wherein the at least one drainage groove is configured to promote runoff flow away from the center of the stormwater chamber and towards the chamber side walls.

9. The flared end ramp of claim 1 , wherein the inlet end of the flared end ramp is configured to conform to an outer surface of the pipe.

10. The flared end ramp of claim 1 , wherein the inlet end of the flared end ramp is configured for placement within the stormwater chamber.

11. The flared end ramp of claim 1 , wherein the inlet end of the flared end ramp is configured to convey material away from an end cap of the stormwater chamber.

12. A method for forming a stormwater chamber, flared end ramp, and inlet cap system for managing flow of material into a stormwater chamber, the method comprising:

providing a flared end ramp having a first end and a second end, and a ramp surface configured to incline from the first end to the second end, the ramp surface including at least one drainage groove extending between the first end and the second end;

forming a support foot attached to the ramp;

providing a stormwater chamber inlet end cap;

connecting the flared end ramp to the chamber inlet end cap; and

attaching the ramp and end cap to the stormwater chamber.

13. The method of claim 12 , wherein the flared end ramp comprises a curved surface meeting and conforming with a shape of an end of a cylindrical stub pipe connected to the inlet end cap.

14. The method of claim 12 , wherein the flared end ramp is configured to connect to an interior surface of the inlet end cap.

15. The method of claim 12 , further comprising:

providing a stub pipe; and

wherein the flared end ramp is connected to the inlet end cap through an intermediate connection with the sub pipe.

16. The method of claim 12 , wherein the chamber inlet end cap is configured to attach to the stormwater chamber and form a chamber enclosure.

17. The method of claim 12 , wherein the at least one drainage groove includes:

a first drainage groove extending along a midline of the inclined surface; and

a second drainage groove angled laterally outward from the inlet end toward the outlet end.

18. A method for containing and filtering stormwater runoff, the method comprising:

providing an inlet apparatus configured to receive runoff from a surface-level drain, the inlet apparatus including at least one of an elevated bypass manifold or an overflow weir;

providing a first stormwater chamber configured for placement underground, the first stormwater chamber being configured to store the runoff and extending between a first end cap with at least one opening and a second end cap;

providing at least one additional stormwater chamber arranged side-by-side with the first stormwater chamber to form an array of stormwater chambers, wherein the array of stormwater chambers is fluidly connected via the inlet apparatus and is configured to receive the runoff from the inlet apparatus wherein each additional stormwater chamber is configured to store stormwater between a first end cap with at least one opening and a second end cap; and

providing a flared end ramp configured for placement within at least one of the stormwater chambers, the flared end ramp including:

an inlet end configured for connection with an inlet pipe, the inlet pipe extending through the at least one opening in the first end cap of the at least one stormwater chamber and connecting to the inlet apparatus;

an outlet end configured for placement within the at least one stormwater chamber; and

an inclined surface extending between the inlet end and the outlet end of the flared end ramp and configured to deliver material from the pipe into the at least one stormwater chamber, wherein the inclined surface includes at least one drainage groove extending between the inlet end of the flared end ramp and the outlet end of the flared end ramp.

19. The method of claim 18 , wherein the array of stormwater chambers comprise open-bottom chambers or cylindrical pipes.
