Proposed Central Refuge Island at Longueville Road – Acquisition of Land at Miladi Parade
PBA 15/1288/1 (job n° 240)
Purpose
To inform the Minister of the land acquisition required to provide a pedestrian refuge island on Longueville Road, and to seek a decision from the Minister as to whether he wishes to proceed with the land acquisition on the in-principle terms agreed with the vendor.
Background
In October 2003, Property Services was instructed by the former Public Services Department to negotiate with the owner of Miladi Parade over the acquisition of a small strip of land at the car-park to allow a “central refuge island” to be constructed at Longueville Road.
The owner of Miladi Parade, Miladi Parade (2001) Ltd, is not a willing seller, but agreement has been reached for the purchase of the land on the terms set-out below.
Current Situation
The terms agreed between Property Services and Miladi Parade (2001) Ltd for the acquisition of the strip of land are as follows:
Area of land to be acquired: | A strip of land along the northern edge of the car-park at Miladi Parade abutting Longueville Road, having an area of approximately 181 sq ft, as shown on drg n° RC/052006 Revision, the land being required to re-align the road to allow the creation of a central refuge island. |
Consideration: | The public will pay Miladi Parade (2001) Ltd the sum of £181[1] for the land to be acquired. |
Compensation: | The public will pay Miladi Parade (2001) Ltd the sum of £10,250 in compensation for the use of the company’s adjacent parking spaces for contractor’s working space during the works. |
The works: | The public will be responsible for all works in connection with re-aligning the road and forming the central refuge island, including all costs. This will include providing a log-roll fence between the new re-aligned pavement on Longueville Road and the Miladi Parade car-park. |
Fees: | The public will meet the reasonable legal fees incurred by Miladi Parade (2001) Ltd in connection with drafting, agreeing and passing the contract before the Royal Court, and also the reasonable fees of the vendor’s surveyor in connection with the negotiations that have taken place. |
Other terms: | The log-roll fence which is to be provided between the new re-aligned pavement on Longueville Road and the Miladi Parade car-park is to comprise 75 mm diameter logs. When provided, it will be in the ownership of Miladi Parade (2001) Ltd, and the public will grant the company access rights onto the Longueville Road pavement to maintain and/or replace the log-roll fence. Miladi Parade (2001) Ltd will be free to amend or replace the log-roll fence subject to obtaining planning consent and complying with any other relevant statutory conditions. |

Recommendation
It is recommended that:
- The public acquires from Miladi Parade (2001) Ltd a strip of land forming the northern edge of the Miladi Parade car-park abutting Longueville Road, having an area of approximately 181 sq ft, in order to re-align the road and pavement to create a central refuge island.
- The public pays a consideration of £181, plus payment of £10,250 in compensation for the use of car-parking spaces as contractor’s working space, plus payment of the vendor’s reasonable legal and surveyor’s fees.
- The public carries-out all work associated with the scheme at its own cost.
- The public provides a log-roll fence on the vendor’s land to separate the car-park from the re-aligned pavement on Longueville Road, and grants the vendor access rights onto the pavement for maintenance and/or replacement purposes.

Pedestrian Crossing Facility at Miladi Parade- Design Considerations
The Department has identified the requirement for measures to address accidents along Longueville Road for some time. However, due to the scattered and diverse nature of the accidents along the length of Longueville Road, there is no single solution to addressing the causes of these accidents. The Department has progressed various schemes as the opportunities have arisen. For example, the installation of high friction surfacing on the junction of Rue des Pres and Longueville Road has reduced the frequency of injury accidents, at this location.
There has been pressure from some residents, as well as their Political Representatives for the area, for a crossing facility at a location near to Miladi Parade. Indeed this local pressure lead to a commitment, by a previous Environment and Public Services Committee, to provide a crossing facility at this point, and funding was sourced from the ‘car-park trading fund’ for pedestrian facility improvements on Longueville Road, as well as on St Aubin’s Road, St Lawrence.
The Department has carried out a review of the area and worked up a design for the most suitable type of crossing in the area.
The design options were:
- Do nothing
- Provide a Zebra Crossing. Approximate cost £5,000
- Install a Pelican Crossing. Approximate cost £15,000
- Build a Central Refuge Island with attendant road carriageway re-alignment. Approximate cost £25,000, excluding the cost of land acquisition.
The above have been listed in order of ascending capital cost. Option 2 would require the paint to be maintained annually, option 3 would have significant on going maintenance and replacement costs every 15 years, while Option 4 would have negligible maintenance costs.
However, balanced against capital and ongoing headline costs as well as ease of installation, it is important that an appropriate crossing type is selected for the site in question.
The average speed of traffic at this site exceeds 35mph. (hourly 85th percentile speeds vary between 33 and 45mph depending on the hour of the day) Design guidance recommends against installing zebra crossings where traffic speeds exceed 35mph.
Research (including local examination of accident statistics) has shown that “under used” pelican crossings have accident rates that are significantly above the average. The traffic signals are triggered on very few occasions and drivers become accustomed to not stopping. However, when the signals are triggered by a pedestrian the red signal may be ignored by drivers leading to accidents to pedestrians on the crossing. Committee report INSTALLATION OF CONTROLLED PEDESTRIAN CROSSINGS dated 13/10/2003 refers.
A central refuge crossing is likely to have a mild traffic calming affect on traffic speeds, as well as preventing inappropriate overtaking in the area, a cause of two of the accidents involving injury to vehicle occupants over the last 4½ years.
The attached plan shows the current distribution of accidents along Longueville Road for the years 2001 to mid 2004.
Surveys indicate that 11 to 12 hundred vehicles per hour use this stretch of road both east bound and west bound for most of the day, and up to 7 pedestrians per hour attempt to cross the road. This may be augmented by suppressed demand if a crossing facility were to be installed at this location.
The cost of an injury accident to society is on average c. £62,000 (UK COBA 1998 prices). One injury accident prevented, during the lifetime of a central refuge crossing facility at this location, would pay the capital cost for that facility.

Maintenance Costs
1. Zebra Belisha Beacons
The belisha beacons are relatively low cost to run and maintain, probably £200 per year. The poles may require replacement at intervals in a salt laden environment. I would anticipate that Longueville would be reasonably benign, as compared to Beaumont and that a pole should make 15 to 20 years. Current replacement costs for a pole would be about £250. The cost of maintaining the white lining of a zebra is influenced by the white panels being in the wheel tracks of vehicles, thus wearing at a faster rate than lines that do not get scrubbed by tyres. The cost of each visit to re-mark a full zebra crossing is of the order £500, including the traffic management which is required to carry out the work.
2. Zebra Astucia Studs
Astucia studs have proved expensive when maintenance is required, though I understand Astucia are working on product revisions to improve maintainability. Currently maintenance on the Astucia studs at the Waterfront is carried out by a technician who visits the Island, when a number of the studs have failed. The cost of the visit is negotiated at the time.
White lining as above.
3. Central Refuge Island
Central refuge Island bollards are again relatively low cost to run and maintain, say no more than £200 per year. The plastic of the bollards degrades over time, and require replacement. I understand such plastic bollards are £100 to £150. The white lining for a refuge tends not to be scrubbed by wheels and can last as much as 4 years in some places. The process of marking these lines is also more straightforward.
4. Pelican Crossing
The day to day maintenance of a modern pelican crossing installation is included in a maintenance agreement we have with Siemens. There is a cost, but it is rolled up with all the other equipment on the Island. However, with a pelican the signal equipment should be replaced every 12 to 15 years depending on the location. The cost of signal equipment replacement, with no attendant civils work is £6000 at current prices.
