Arapahoe County

Project: Regal Office Building (Regal Electric – New Office Building)
Location: 12707 E. Jamison Place, Englewood, Colorado (Arapahoe County)
Project Type: Commercial (Office + Warehouse)
Site Area: 2.309 acres
Momentum Role: Civil Design + Entitlements (Site/Civil + Drainage + GESC)

Overview

Overview

Momentum Civil Consultants provided civil engineering and entitlement support for Regal Electric’s new office/warehouse facility in the Dove Valley Business Park area. The development features a 12,000 SF commercial building purpose-planned for both operations and administration—approximately 5,800 SF of warehouse and 6,200 SF of office space—paired with site improvements that support functionality, access, and long-term maintainability.

The site is adjacent to Lone Tree Creek, requiring careful coordination of drainage compliance, water quality features, and construction-phase stormwater controls while maintaining existing drainage patterns and avoiding floodplain impacts.

Key Elements

• Balanced office + warehouse program: 12,000 SF total building area supporting both warehouse and office functions
• Efficient site layout: 33 parking spaces (including ADA), access from E. Jamison Place, and an outdoor storage yard component
• Drainage + water quality design: storm sewer collection and outfall toward Lone Tree Creek with site water quality measures (including a grass buffer and protection details to reduce sediment/gravel migration)
• Regulatory coordination: Arapahoe County and SEMSWA review cycles supported through formal response letters, revisions, and certification documents

Momentum’s Services (Civil Design + Entitlements)

Momentum supported the project from early civil design through permit-ready deliverables, including:

• Entitlement and agency coordination through the Administrative Site Plan (ASP) process (Arapahoe County) and drainage/GESC review (SEMSWA)
• Site layout, grading, and utility design (civil construction plan set including grading, utilities, storm sewer plan/profile, paving, and details)
• Phase III Drainage Report documenting existing and proposed drainage conditions, drainage basin mapping, and compliance with applicable criteria
•  GESC(Grading, Erosion & Sediment Control) plan + report to support permitting and construction-phase stormwater compliance
• Floodplain coordination and documentation, including an Engineer’s Certification of No Impact confirming improvements were outside mapped floodplain/floodway and would not increase floodplain impacts
• Public improvement support, including an engineer’s cost estimate and collateral documentation for drainage-related public improvements
• Easement support as needed for drainage features (legal description prepared for a drainage easement area)

Outcome / Value Momentum delivered a coordinated civil design package and entitlement support that helped position the Regal Office Building for approvals and permitting with Arapahoe County and SEMSWA—balancing a high-functioning commercial site plan with drainage, water quality, and construction-phase compliance near Lone Tree Creek.
