II. SCOPE OF WORK

Task 1. Site Preparation and Mobilization

Construction sequencing and site preparation shall occur according to plans titled, “CULVERT MODIFICATIONS PLAN & PROFILE” and “LAKELAND ASSOCIATION BEACH,” prepared by Underwood Engineers (2025), as well as project-specific conditions identified in the approved permits from NHDES.

Task 2. Culvert Modification

The culvert modifications shown on the Plan titled, “CULVERT MODIFICATIONS PLAN &

PROFILE” (Underwood Engineers, 2025), include a culvert improvement at an unnamed perennial Tier 1 stream crossing that runs across Lake Shore Drive and has an outfall that leads into Sunrise Lake. Approximately 64 linear feet of the existing 24" CMP culvert will be removed, with only 16 linear feet being replaced. The remaining 48 linear feet will be daylighted in a natural channel with native plantings to simulate a natural stream.

Task 3. Stormwater Control Measures – Rain Garden (RG#1) and Swale

The stormwater control measures on the Plan titled, “LAKELAND ASSOCIATION BEACH”

(RG#1) and the subsequent 4-foot-wide riprap swale is the minimum construction requirement for the proposed stormwater control measure associated with this request for bids. It is designed to be oval-shaped (31' x 21') with 2:1 slopes.

Task 4. Post-Construction Site Stabilization

Site restoration shall occur according to plans titled, “CULVERT MODIFICATIONS PLAN &

PROFILE” and “LAKELAND ASSOCIATION BEACH,” prepared by Underwood Engineers

(2025), as well as project-specific conditions identified in the approved permits from

NHDES.
