The Chigwell Brook along this section is a relatively natural woodland brook. The stretch includes three long culverts, however it is unclear why culverting was put in place at all. The proposal is simply to remove the line of three culverts, the elongated headwalls and the concrete revetment upstream and downstream of each structure. The brook is shaded by the mature trees growing within the valley. There is little marginal vegetation, but this can be expected (RCTshredder communities). The bed is primarily exposed gravels. FRM should be improved; the cross-sectional flow capacity is likely to be improved as the culverts are fairly low and narrow. Debris was apparent at the mouth of one culvert at the time of survey. Ongoing maintenance should be lowered by the proposal as the risk of significant obstruction from debris at the mouth of the culverts will be removed.
