A summary figure showing the project layout and a breakdown of the project cost by trail segment is included as Attachment B to this Staff Report. For ease of preparation, the cost for the modular block retaining walls has been included with the turf restoration on that figure. It should be noted that the CIP was developed in March 2006, prior to the development of the Landscape and Architectural Element Plan, which was ordered for the CR 10 corridor on August 28, 2006. Lighting: Decorative Lighting As was constructed on Trail Segments 9 & 10, the proposed lighting for Trail Segments 1 – 5 includes standard pole-mounted lighting for a majority of the project length, with decorative lighting provided at key locations, such as intersections. There are 11 locations where a decorative light fixture is proposed to be installed along Trail Segments 1 – 5. The decorative lights are more expensive than standard lights. Therefore, further reduction in project cost could be achieved by reducing or removing the decorative lighting if the City so wished. As estimated in the November 2007 Preliminary Report, the cost per light is approximately $1,800 for the standard shoebox lighting unit and approximately $4, 300 for the decorative lighting units. If all 11 proposed decorative lights were replaced with standard units, the project cost could be reduced by an additional $27,500. This represents only 2% of the total estimated project cost of $1,274,512. Given this small relative savings, it is the recommendation of Staff that the decorative lights be used on the Trail Segments 1 – 5 project, for consistency with the previous and future trail projects that will be performed along the County Road 10 corridor. LED (Light Emitting Diode) Lighting The City Council had previously asked Staff to look into the costs and benefits of LED lighting along the trail corridor. LED lighting is still a developing technology and options for overhead lighting are limited. Local distributors have estimated that overhead LED fixtures will cost approximately $4,200 per unit and that the light produced may be less than a standard lighting unit, possibly requiring additional lights. This increased cost and restricted budget do not make it feasible to include LED lighting in this project at the time of construction. However manufacturers are beginning to develop products for the retrofit of existing lighting fixtures with LED lights. Therefore if standard lighting units were installed on the Trail Segments 1 – 5 project with initial construction, it would be possible to retrofit the units with LED lights at a future time. As the LED technology continues to develop, it is likely that the cost will decrease.
