Denemarken – Kustverdedigingswerken – Køge Dige – Diger, højvandsmure og højvandsport i Snogebækken

Køge is in the course of time hit by some particularly powerful storm surges and has therefore been flooded several times. As a result of the climate-related sea-level rise, the frequency of flooding in Køge is expected to increase in the future. The state has designated Køge Bugt as a risk area for flooding in accordance with the EU's Floods Directive. On this basis, Køge Municipality has initiated a coastal protection project, Køge Dige. Køge Dige aims to protect Køge Municipality's coastal urban areas from flooding from the sea, and when completed, it will stretch over most of Køge Municipality's coastline from Skensved Å in the north, down to Køge Harbour and to Vedskølle Å in the south. The coastal protection will consist of dikes, seawalls and floodgates, as well as pumps for handling water from the hinterland. Køge Dige is divided into three sub-areas:

Sub-area 1: Københavnsvej. The northern part, which stretches from the municipal boundary to Solrød Municipality to the point along Værtsvej, north of Køge Marina, where the existing terrain itself becomes sufficiently high to provide protection. Here, the coastal protection is established as a starting point as a dike east of Københavnsvej and outside the urban areas east of Københavnsvej, as well as a floodgate in Snogebækken. At Havstokken, a combination of seawall and dike is established over a short distance. Pump stations in this sub-area are offered separately and must be established in another enterprise - not included in the current tender.

Sub-area 2: Køge Marina and Køge Harbour. The central part of Køge Dige includes Køge Marina and Køge Harbour. In this part, the coastal protection consists of seawalls and terrain elevations on the northern part of the harbour, as well as a large floodgate in the public harbour (Slipset). The task of establishing the large floodgate in Køge Harbour, with the associated port canal and pump station, is offered in a separate tender with the associated delivery contract, and it is not part of the current enterprise - not included in the current tender. At Søndre Havn, it is only the coastal protection at Køge Roklub that is included as part of Køge Dige and the current tender.

Sub-area 3: Strandvejen. The southern area covers the stretch from Strandpromenaden at Kjøge Miniby to Vedskølle Å. Here, Strandvejen serves as the protection for most of the stretch. A dike is established around Hotel Comwell, and the forest road that runs through a forest area immediately north of Vedskølle Å is raised. The main contract to be tendered includes flood/coastal protection in the three sub-areas by establishing approximately:

• 5,000 metres of dikes

• 1,900 metres of ditches along the back of the dikes

• Incorporation of approx. 75,000 cubic metres of soil

• 1,400 metres of floodwalls/spunds with openings for culverts

• 400 metres of terrain regulation

• Floodgate in Snogebækken

The construction work to be tendered is described in more detail in the tender material.
