27th Jan 2015 – Update on Dam Works at Highams Park Lake from City of London Corporation

Dear  All 

Please find attached the latest update on the works at Highams Park Dam. If you have any queries please do contact me at the address below.

Scouts Hut Floodwall

The floodwall is now entirely brick clad and the coping stones are being installed. Once anti-graffiti coating is applied, the floodwall will be completed.

Landing Stage

Repair works to the concrete landing stage on top of the dam are almost complete. New timber fenders have been provided to help the launch of canoes on the lake in the future.

Footbridge

The new footbridge has been installed. Due to the need to fit the new floodwall in we have had to narrow the footbridge slightly.

Drawdown structure

The drawdown structure will enable the water level in the lake to be lowered in an emergency situation and for maintenance purposes. The inlet structure is now complete and the pipe units have been laid. The outlet structure is being brick clad and the coping stones will be installed shortly thereafter. Erosion protection will be provided in the River Ching as well. Both the inlet and outlet structure will be fitted with equipment to enable the safe operation of the structure in the future.

Spillway works

 The spillway works will commence shortly. The spillway will ensure that floodwater flows over the dam safely. The rear slope of the dam will be slackened and a turf reinforcement material installed, before the slope is seeded. The turf reinforcement material will serve to increase the erosion properties of grass.

Following completion of the spillway works, the scheme area will be landscaped: this will include new trees and shrubs, an area of wildflower seeding, together with a new footpath, bike stands and the benches will be reinstated.
