LANDSCAPE AND MAINTENANCE NOTES:

PLANTING ZONE 1

1. PLANTING ZONE 1 IS LOCATED IN THE STREAM CHANNEL AND ALONG THE BANKS

AND BED OF REACH 1. ANNUAL MAINTENANCE WILL BE REQUIRED TO MAINTAIN

HERBACEOUS COVER AND PREVENT COLONIZATION BY WOODY SPECIES, BOTH OF

WHICH ARE REQUIRED TO MAINTAIN DRAINAGE EFFICIENCY AFTER

CONSTRUCTION. AT THE END OF THE FIRST GROWING SEASON AFTER

CONSTRUCTION, USE A MOWER, STRING TRIMMER, OR OTHER MECHANISM TO

REMOVE ALL WOODY SPECIES THAT VOLUNTEER ALONG THE BED AND BANKS.

EACH YEAR THEREAFTER, CONDUCT ANNUAL MOWING OR TRIMMING DURING THE

GROWING SEASON ALONG THE ENTIRE REACH TO REDUCE THE HEIGHT OF

VEGETATION TO A HEIGHT BETWEEN 6 AND 8 INCHES. AT THIS TIME, WOODY

SPECIES AND INVASIVE WEEDS ARE TO BE REMOVED BY HAND OR TREATED WITH

AN APPROVED HERBICIDE. MOWING OR TRIMMING ACTIVITIES SHALL BE

CONDUCTED WITH CARE SO AS NOT TO CAUSE EROSION OR DAMAGE TO

INFRASTRUCTURE.

2. IN ADDITION TO VEGETATION MANAGEMENT, MONITORING OF THE CHANNEL

WITHIN REACH 1 IS RECOMMENDED TO DETECT SEDIMENT ACCUMULATION

WITHIN THE BED WHICH WILL REDUCE DRAINAGE EFFICIENCY. MONITORING

SHALL CONSIST OF THE ESTABLISHMENT OF THREE PERMANENT CROSS SECTIONS

WITHIN THE REACH. EACH SECTION SHALL BE PERPENDICULAR TO THE FLOW

PATH AND SHALL INCLUDE PERMANENT MONUMENTS ON EITHER SIDE OF THE

CHANNEL. THE MONUMENTS CAN BE EITHER CAPPED RE-BAR, OR STAINLESS

STEEL STOVE BOLTS SET INTO CONCRETE, SET 2-5 INCHES ABOVE THE GROUND

SURFACE. THE MONUMENTS SHALL BE ESTABLISHED IMMEDIATELY FOLLOWING

CONSTRUCTION AND SHALL BE LOCATED AND ENTERED INTO THE NAVY'S GIS

DATABASE. THE CROSS SECTIONS SHALL BE SURVEYED FOLLOWING

STABILIZATION AFTER CONSTRUCTION; THESE DATA WILL SERVE AS THE

BASELINE FOR COMPARISON. SUBSEQUENT SURVEYS ARE THEN TO BE

CONDUCTED EVERY TWO YEARS TO ASSESS CHANNEL CONDITIONS AND

DETERMINE IF SEDIMENTATION / AGGRADATION IS OCCURRING.

PLANTING ZONES 2 AND 4

1. PLANTING ZONE 2 IS LOCATED ALONG THE TOP OF BANKS WITH A PURPOSE OF

REPLACING EXISTING FOREST THAT WAS REMOVED DURING THE CONSTRUCTION

PROCESS AND ESTABLISHING RIPARIAN BUFFERS IN AREAS THAT WILL NOT

INTERFERE WITH EXISTING UTILITIES, INFRASTRUCTURE OR OPERATIONS.

PLANTING ZONE 4 IS SIMILAR TO ZONE 2 BUT WITH AN EMPHASIS ON LOWER

GROWING TREES AND SHRUBS WITH MORE ORNAMENTAL APPEAL. DURING THE

FIRST GROWING SEASON, PERIODIC MOWING OF THE NATIVE GRASS / PLANT

GROUND COVER MAY BE NEEDED TO REMOVE INVASIVE WEED AND WOODY

SPECIES. FOR THE SECOND YEAR AND BEYOND, MOW THE GROUNDCOVER ONCE

ANNUALLY AT THE BEGINNING OF THE GROWING SEASON. AT THIS TIME, ALSO

INSPECT FOR INVASIVE WEED OR WOODY SPECIES AND REMOVE AS NEEDED.

CARE IS TO BE TAKEN NOT TO DAMAGE ANY TREES OR SHRUBS PLANTED

INTENTIONALLY.

2. DURING LANDSCAPE INSTALLATION, BUCK GUARDS AND OTHER PROTECTIVE

DEVICES WILL BE INSTALLED TO PROTECT TREES AND SHRUBS FROM DEER

DAMAGE. OVER TIME AS THE TREES AND SHRUBS MATURE AND BECOME

ESTABLISHED, THESE PROTECTIVE MEASURES CAN BE REMOVED IF THEY PRESENT

A DANGER OR BEGIN TO INHIBIT GROWTH.

PLANTING ZONE 3

1. PLANTING ZONE 3 IS A LAWN AREA INTENDED TO PROVIDE EASY MAINTENANCE

ACCESS TO INFRASTRUCTURE WHILE PROTECTING UNDERGROUND UTILITIES

FROM ROOT DAMAGE AND MAINTAINING SIGHT LINE NEAR ROADS. THIS

PLANTING ZONE IS TO BE MOWED TO A MAXIMUM OF 6 INCHES THROUGHOUT THE

GROWING SEASON.

PLANTING ZONE 4

1. Planting zone 1 is located in the stream channel and along the banks and bed of this zone. Annual maintenance will be required to maintain herbaceous cover and prevent colonization by woody species, both of which are required to maintain drainage efficiency after construction.

a. At the end of the first growing season after construction, use a mower, string trimmer, or other mechanism to remove all woody species that grow along the bed and banks.

b. Throughout the growing season, conduct mowing and trimming within the entire zone to maintain vegetation to a height between 6 and 8 inches.

c. At the beginning of each growing season, woody species and invasive weeds are to be removed by hand or treated with an approved herbicide.

d. All mowing or trimming activities shall be conducted with care so as not to cause erosion or damage to infrastructure.

PLANTING ZONE 1

PLANTING ZONES 2 AND 4

1. Planting zone 2 is located along the top of banks with a purpose of replacing existing forest that was removed during the construction process and establishing riparian buffers in areas that will not interfere with existing utilities, infrastructure or operations. Planting zone 4 is similar to zone 2 but with an emphasis on lower growing trees and shrubs with more ornamental appeal.

a. Monthly during the first growing season mow the native grass / plant ground cover to remove invasive weed and woody species maintaining a height of 8 inches.

b. For the second year and beyond, mow the groundcover once annually at the beginning of the growing season.

c. At the beginning of the growing season each year, inspect for invasive weed or woody species and remove as needed in same manner as item C for zone one.

d. Care is to be taken not to damage any trees or shrubs planted intentionally.

2. During landscape installation, buck guards and other protective devices will be installed to protect trees and shrubs from deer damage.

a. These protective devices can be removed if they present a danger or begin to inhibit growth.

PLANTING ZONE 3

1. Planting zone 3 is a lawn area intended to provide easy maintenance access to infrastructure while protecting underground utilities from root damage and maintaining sight line near roads.

a. This planting zone is to be mowed to a maximum of 6 inches throughout the growing season.
