Consultant presents plant palette and phased cost menu for Leguay roundabout gateway
Summary
DTJ Design presented a concept palette and phased construction approach for the Leguay (entry) roundabout, emphasizing low‑water, low‑maintenance plantings, a menu of hardscape/landscape options and a phased cost estimate; consultant cautioned that phasing increases mobilization and traffic control costs.
The Castle Pines Parks & Recreation Advisory Board heard a concept‑level presentation from DTJ Design on Feb. 27 about landscaping and phasing for the Leguay roundabout and surrounding entry approaches.
David (DTJ Design) said the objective is a low‑water, naturalized planting palette that provides year‑round visual interest with minimal maintenance. He described a so‑called "bulletproof" selection—drought‑tolerant shrubs, evergreen structure for winter contrast and ornamental grasses that give seasonal color—while limiting labor‑intensive plantings and using accent plantings sparingly to create a distinct gateway identity that aligns with other Castle Pines entry treatments.
DTJ showed a phased scheme that separates hardscape (phase 1a) and center planting (1b), then addresses approach corridors in later phases, and a lower‑priority phase for native reseed and additional trees. The firm proposed an itemized, menu‑style cost estimate so the city can pick components to match funding priorities. In discussion, the consultant compared the roundabout entry estimate to a recent East‑of‑I‑25 monument project and described the roundabout as achievable inside typical gateway budgets, while noting the project’s landscape intensity makes it costlier than a plain monument sign.
Dave warned the board that breaking construction into multiple phases often increases overall costs because mobilization, traffic control and other general‑conditions expenses repeat with each separate construction mobilization. He also confirmed that irrigation and controller boxes are built into the landscape line items and that most planting areas are planned for drip irrigation; water taps or water‑supply fees were not included in the presented line items.
Board members asked about potential cost reductions (for example, reducing tree counts or simplifying lighting) and were advised that the itemized menu allows those adjustments. The consultant said staff and council will still need to weigh tradeoffs between a one‑time, larger build and multi‑phase delivery.
Ending: The board thanked DTJ for the presentation; staff will present the phasing and cost information to council at a forthcoming study session for further direction.
