Document Description
The project would include renovations and additions to the existing 9.6-acre Ellis Lake Park (Park) such as renewal of existing amenities, addition of new amenities, added security measures, and beautification of the Park’s natural elements. The project objective is to increase access, security, and both passive and active enjoyment of the Park. Park renovations would include renewing and replacing the existing path throughout the Park by widening the existing path around Ellis Lake to a 15,000 square foot path. The project would also include the addition of 8,000 square feet of trail for biking and running that would connect Laguna Street to Clayton Road. The project would renew existing pathways to provide 25,000 square feet of pathway for Americans with Disabilities Act (ADA) enhancements. Existing concrete paths would be replaced to accommodate ADA accessibility. The project would also include updates to the Park’s playground amenities, including replacement of wood chips with softer foam surface material. The existing parking area would be expanded by approximately 6,400 square feet off Clayton Road. The expansion would include 17 new parking spaces. Renovations would also include trimming unhealthy vegetation and “dredging” the lake to improve water quality. The dredging activity would include removing particles from Ellis Lake and improving water quality. Dredging would not disturb sediment at the bottom of the lake. Three safety barriers would be added to Ellis Lake during dredging to maintain the lake’s shoreline. The safety barriers would occur outside of the dripline of the trees, where feasible. Tree maintenance and trimming would occur at existing trees surrounding the northeastern portion of Ellis Lake. Existing earthen mounds throughout the Park would be leveled as part of the project. Remaining grassed areas would be graded to allow for full visibility throughout the Park for visitors and for security by Concord staff monitoring the Park. A total of 23,000 cubic yards of earthen material would be leveled and contoured throughout the Park (15,000 cubic yards for leveling the mounds and 8,000 cubic yards for contouring grassed areas). The project would add new amenities to the Park including a basketball court, two community gardens, seating, and barbecue equipment. The proposed basketball court would be a 4,284 square foot concrete slab with lighting and fencing located east of the existing parking lot. The two community gardens would each include 15 to 20 filled 40 square foot garden beds with irrigation and fencing to offer community access to planting and gardening. One garden would be located in the southeast portion of the Park and the second garden would be located south of Clayton Road and west of the Keller House. The project would include six shaded seating tables throughout the Park. The new barbecue area with three barbecues would be located east of Ellis Street at the northern portion of Ellis Lake. Two new playgrounds and one playground renovation are proposed within the Park. In addition, an adult exercise area would be added east of the existing parking lot near a proposed playground. To address current security concerns security lighting a total of 20 solar security lights would be added throughout the Park. To allow for larger hosted events, a stage area with a shaded cover would be constructed extending on piers into the lake’s edge. The round stage would include up to six piles for a total of approximately 42.4 square feet of fill. Public art is proposed on and near the stage, as well as along the proposed fence screening the rear of the Ashbury Lane properties.
