DEFINITIONS AND ACRONYMS

DEFINITION/ACRONYM DESCRIPTION

Aeration Introduction of air into the soil by mechanical means to promote health and growth.

Appearance Where there is a sense impression or outward aspect of an area or thing that is consistent, uniform and neat in and around the surroundings.

ATFP Anti-Terrorism Force Protection

Artificial Turf An artificial surface that resembles grass.

BASH Bird Aircraft Strike Hazard

Berm A mound or bank of earth typically used as a barrier.

Bioretention Areas Bioretention areas are shallow landscaped depressions that treat storm water runoff.

BMP Best Management Practices: Inspection and Maintenance for Discharge of Storm

Water from Small Municipal Separate Storm Water Systems (MS4) issued by the

Virginia Department of Environmental Quality. (VA DEQ). Described as a type of water pollution control. Historically the term has referred to auxiliary pollution controls in the fields of industrial wastewater control and municipal sewage control, while in storm water management (both urban and rural) and wetland management, BMPs may refer to a principal control or treatment technique as well.

Brow Ditch A drainage ditch with sufficient slope to prevent erosion of adjacent grading.

Bruising of Lawn An injury to grass areas resulting in discolored blades of grass, usually caused by mowing with a dull blade.

Caliper The measurement of a tree trunk at its widest diameter, measured six inches up from the ground for trees under four inch caliper, and twelve inches from the ground for trees over four inch caliper. Multi-stem plants are measured at the widest point of all trunks, six inches up from the ground for trees under four inch caliper, and twelve inches from the ground for trees over four inch caliper.

Classification and Ordering of Plants

For the purposes of pruning, trimming, planting, or removal, specific plants shall be identified according to their type and application as specified in the American

Objective

The objective of the project was to design and construct LID retrofit BMPs in the drainage areas of several outfalls at NNSY. The NNSY drainage areas served by the BMPs (outfalls 012, 014 and 025) are located in the northern port l on of the activity, outside the Controlled Industrial

Area.

Site History

Since the NNSV is in the Elizabeth River watershed and hold Virginia Pollutant Discharge

Elimination System permits for both municipal and industrial storm water discharges, the

Department of Defense Chesapeake Bay Program coordinator decided to implement LID demonstration projects on the installation. The demonstration project will allow the Navy to assess the effectiveness of a number of LID features and provide examples for use in future Nave projects.

LIDBMP

Description

The foundation planters (also known as storm water planters) are constructed of masonry type precast stone and were installed adjacent to the exterior of a building. The purpose of the planters ls to treat roof runoff by diverting flows from the gutter/downspout system to the planter. Other sources of water such as cooling-system condensate, can also be diverted to the foundation planter, but were not rerouted for this task order.

The runoff Is treated by the vegetation and soil in the planter. The types of plants installed in the planters are dwarf mondo grass

(Orphopogon jaonicus) and creeping blus emerald phlox (Phlox subulata). These plants were selected to meet anti - terrorism/force protection requirements.

The foundation planters, consist of the container, vegetation, mulch layer, soil layer, and underdrain system. The underdrain system drains underneath the planter onto the sidewalk, for all planters except planter FP7-04, which has a 4-inch polyvinyl chloride (PVC) effluent pipe for sampling purposed that extends through the side wall and discharges to the side walk. This planter will be monitored for influent and effluent quality. Nine foundation planters were constructed under the demonstration project, see attached inventory.

Bio-retention

Facilities

Bio-retention facilities are planted areas installed in shallow depressions. In Virginia, these facilities consist of several major parts: a ground cover layer (surface mulch), planting soil, in situ soil, vegetation, and Inlet and outlet controls (including underdrain system).

They also can be located in existing green areas, treating runoff from surrounding streets, buildings, and parking lots.

Storm water enters the BMP via grassed channels at the north and south ends of the site, as well as through the drop inlet on McKeever Avenue just south of Breese Street. The bio-retention area underdrain system connects to the storm water system at the drop inlet located on the south side

The bio-retention area at NNSY, north of Building 67, was constructed where an abandoned rail spur bisected a grassy area. The

BMP treats runoff from parking spaces and roadways (McKeever Avenue east side, Breese Street south side, and Rowan Avenue west side) adjacent to the grassy area. The bio-retention facility reduces runoff volume mostly through infiltration and also provides some detention. For water quality control, bio-retention combines physical filtering and absorption with biological processes. Bio-retention facilities can be located In a parking lot, at the center of each parking row, and at the edge of the parking lot. Storm water enters the BMP via grassed channels at the north and south ends of the site, as well as through the drop inlet on McKeever Avenue just south of Breese Street. The bio-retention area underdrain system connects to the storm water system at the drop inlet located on the south side of Breese Street just east of McKeever

Avenue. The discharge is ultimately conveyed to the Southern Brance of the Elizabeth River via outfall 025.

The following vegetation was planted at this bioretention facility: river birch (Betula nigra), winterberry llex ventidllata), inkberry (llex glabra), cinnamon fern (Osmunda cinnamomea), Shenandoah grass (Panlcum vlrgatum), cardinal flower (Lobelia cardinalis), and Japanese variegated iris (Iris ensta).

Frequency Of

Service

Annual (A). Services performed once during each 12-month period of the contract at intervals of 335 to 395 days.

Semiannual (SA). Services performed twice during each 12-month period of the contract. Intervals 3/15 to

4/30 and 10/1to 11/30. Quarterly (Q). Services performed four times during each 12-month period of the contract at intervals of 80 to 100 calendar days.

Foundation

Planter

Container

The planter container holds the filter media and vegetation. Structural deficiencies (if any) In the planter including cracks and failure should be repaired as needed. Extra precast landscaping block is available from Lancaster Farms in the event that damage Is significant and specific stone pieces must be replaced.

Mulch Layer

Foundation planters were mulched with shredded hardwood after the planting of vegetation was completed.

It ls recommended that the mulch layer be maintained at a 2 to 3-inch thickness. Shredded hardwood mulch should be replenished at least annually. The older mulch will serve as the organic layer once new mulch is applied. When the mulch layer is replenished the previous layer may need to be removed first. If water ponds for greater than 12 hours or the organic layer reaches a depth that would cause the surface of new mulch to be higher than the plants, part of the organic layer should be removed.

Planting Soil

Layer

The planting soil ls a mixture of 50 percent sand, 25 percent composted leaves, and 25 percent soil and was obtained from Ghent Gardens. In urban environments, soil tends to become acidic due to precipitation and the influences of storm water runoff. For this reason, it is recommended that the application of limestone or another alkaline soil amendment be considered once to twice a year. Testing of the pH of the soil should precede the limestone application to determine the amount required.

Planter

Vegetation

Planter vegetation should be Irrigated as needed. Fallen leaves and debris from deciduous plant foliage will be removed to the extent practicable. Vegetation should be replaced to maintain cover density and control erosion where soils are exposed.

Vegetation upkeep will include addressing problems associated with disease or insect infestation and replacing dead or diseased vegetation. Dead vegetation should be removed and replaced to maintain less than 10 percent of area coverage at full growth or when planter function is impaired.

Planter

Underdrain

System

The planter reservoir receives and detains storm water prior to infiltration. If water does not drain from reservoir with twelve hours of a storm event, sources of clogging should be identified and corrected. If the intake screen at the bottom of the PVC reverse bend overflow pipe is clogged, mulch or debris should be removed from the area. If the intake from the overflow pipe Is not obstructed, the typical solution for clogging is to scrape and replace the top layer of soil.

Bioretention

Vegetation

Vegetation upkeep should include addressing problems associated with disease or insect infestation, replacing dead or diseased vegetation, and any necessary pruning. The plants have been selected from native species that require low maintenance. However, the vegetation should be irrigated in case a severe drought. Fallen leaves and debris from deciduous plat foliage should be removed to the extent practicable.

Dead vegetation should be removed to maintain less that 10 percent of full growth of area coverage or when bio-retention function is impaired. Vegetation should be replaced to maintain cover density and control erosion where soils are exposed.

Title Description

Bioretention

Inlet And

Outlet

Structures

The bio-retention area has three inlets. There are grass entry channels at the north and south ends of the bio-retention cell. These inlets should be kept free of sediment and debris that impede flow into the BMP and cause ponding on the surrounding roadways. The third inlet is a plastic riser structure at the northwest part of the bio-retention area that receives piped flow from the drop inlet on the east side of McKeever Avenue

Oust south of Breese Street) and conveys it to the surface of the Street) and conveys it to the surface of the

Bio-retention cell. These structures and pipe should be kept free of sediment and debris to prevent clogging

The bio-retention ponding area receives and detains storm water prior to infiltration. If water does not drain from reservoir within twelve hours of a storm event, sources of clogging should be identified and corrected.

One potential cause is clogging of the overflow grate. Debris should be removed from the surface of the grate to allow excess water to exit via the overflow system. If the-obe, Flow grate is unobstructed, the typical solution to alleviate clogging is to scrape and replace the top layer of soil. If there is no clogging but sediment accumulates or the organic layer increases such that treatment/ponding capacity is reduced, the organic layer should be removed to bring the elevation to 9 inches below the elevation of the overflow grate

(the top of the 3-inch mulch layer would be 6 inches below the elevation of the overflow grate)
