Life Sciences

Clark | Azar & Associates was the civil engineer for the design of a new 142,000 SF, 4-floor, state-of-the-art life sciences building located on 33 acres in the I-270 life sciences corridor. The ground-up development achieved LEED Gold through sustainable site design, electrical charging stations and interior systems.

The 4-acre site for this building is part of a larger mixed-use development located within the City of Gaithersburg. It required coordination with, and permitting through, multiple state, county and local agencies including Maryland State Highway Administration (SHA), Montgomery County DPS and DOT, Washington Suburban Sanitary Commission and the City of Gaithersburg. Additional coordination was required within the developer’s condominium association and associated agreements.

Site Design & Construction

Clark | Azar’s site design included parking, stormwater management and utilities on this vacant site. To make the project viable, a previously planned and approved parking garage was reconsidered and additional parking was provided on the site. This reduced the opportunity for traditional stormwater management designs and therefore resulted in the addition of five micro-bioretention facilities designed with retaining walls to maximize surface area, along with a proprietary Bioclean Wetland System and underground storage to meet city stormwater requirements.

Clark | Azar also designed an extension to an asphalt walking trail to the intersection of a county and state road. This trail extended into the SHA right-of-way and therefore required a separate stormwater management facility. Clark | Azar designed 176 parking spaces on the site and developed a Stormwater Pollution Prevention Plan.

Due Diligence

The CAA team provided site design and/or permitting and bond services for more than 500 7-Eleven convenience stores and gas stations in Maryland, Virginia, West Virginia, Delaware and the District of Columbia. CAA’s principals have provided full site design services from the Due Diligence phase through Construction Administration.

The Due Diligence phase includes preliminary research on zoning, permitting requirements, and environmental constraints. The results of the finding are summarized in a brief report and executive summary suitable for the real estate division to make its final determinations on moving forward with a site.

Site Design

Site Design services start with a conceptual stage, where the CAA team provided preliminary layouts, coordinated ALTA surveys, and prepared development schedules. Staff assisted in obtaining zoning approvals, special exceptions and entitlements. Final design included stormwater management plans, sediment control plans, water and sewer plans, landscape plans, lighting plans, relevant site details, and grading plans. Our staff processed all site-related and building permits and bonds and coordinated all utility services for the stores.

Construction

During construction, the team provided on-call services including inspections and/or supervision of site construction items. Record drawings for site features such as storm drain and stormwater management facilities were prepared.

Home 2 Suites Hotel

Woodbridge, Virginia

Mobirise

Amenities

CAA designed a new Home 2 Suites Hotel near the Potomac Mills outlet mall. The existing site was a single family residential house surrounded by forest. The site is narrow and long, with a steep drop off towards a stream at the rear of the property.

CAA provided site design and permitting for a turn lane and the expansion of Telegraph Road, a commercial entrance, parking and pedestrian access, a parking deck, site lighting, landscaping, grading, retaining walls, domestic water and fire line design, sanitary sewer connection, underground stormwater storage and treatment, and stormwater outfall improvements.

Site Design & Construction

The project required rezoning and a site plan process to allow a hotel on the formerly residential site. Part of the proffers of the rezoning was to provide several sustainable features as well as expanded pedestrian connection. The hotel provides an underground rainwater harvesting cistern for reusable water for landscape irrigation.

The existing stormwater outfall on the site was heavily eroded, as was the stream itself. To assuage these issues, two underground storage and treatment systems were designed to reduce the post construction flows below the existing 2, 10, and 100-yr storm flows. A series of rip rap plunge pools were added to further reduce any possible erosion.

Residential Communities

Berkeley County, West Virginia

Mobirise

Waterford Glen

CAA designing a subdivision consisting of 179 single family homes, 74 townhomes and 17 duplex units on 110 acres of vacant farmland in Berkeley County, West Virginia. The project consists of grading, paving and utilities installation. The proposed subdivision conforms to the requirements and methodology of the State of West Virginia and Berkeley County regulations.

Through the implementation of low impact design measures such as reducing the width of the roadways, open section as opposed to curb and gutter, and the use of grass shoulders rather than gravel, the team was able to reduce the proposed impervious area by 20% from the concept design. The result is a development which meets the environmental intent of the county and the state.

Stormwater Management for the site was achieved via grass swales and 15 micro-bioretention areas. The outfall pipe for the subdivision is only 18” which required stormwater management quantity control via 5 detention ponds, one of which is over 7 acres in surface area. There are 3 miles of 8-inch gravity sewer and a pump station
