ARTICLE I. STORMWATER MANAGEMENT
Sec. 35-6. Stormwater management technical standards.
(a) General stormwater management technical standards. All land disturbing activities regulated pursuant to this article within the city shall comply with the following general technical standards:
(1) Land disturbance shall be limited to the area necessary to provide for the proposed use or development. In accordance with an approved grading plan, the limits of land disturbance, including clearing or grading, shall be strictly defined. These limits shall be clearly shown on submitted plans and physically marked on the development site.
(2) Existing indigenous vegetation and trees shall be preserved to the maximum extent practicable, consistent with the proposed use or development, in accordance with chapters 14 and 44, pertaining respectively to environment and vegetation, and as follows:
a. Existing trees over two inches in DBH and shrubs greater than five feet in height shall be preserved outside the approved construction footprint consistent with subsection (a)(1) of this section. Diseased or weakened trees, by age, storm, fire or other injury, may be required to be removed, by the director.
b. The regulation of any historic, specimen, street, park, memorial and other public trees shall be regulated in accordance with chapter 44, pertaining to vegetation. This may include the bonding of these types of trees in situations where the critical root zone (CRZ) or canopies extend onto the site.
c. Clearing shall be allowed only to provide necessary access, positive site drainage, water quality BMPs and the installation of utilities.
d. Tree preservation shall be in accordance with the City of Falls Church Tree Preservation Standards and Specifications. A copy of the approved plan and the specifications shall be kept on-site at all times.
e. Prior to clearing and grading, tree preservation fencing, consistent with the City of Falls Church Tree Preservation Standards and Specifications, signs, or other such material may be required by the director. These preservation measures shall be installed to protect the CRZ of any woody vegetation to be preserved on the site, as well as to protect the CRZ of any woody vegetation trees on adjacent properties including rights-of-way that extend onto the site.
f. Tree preservation fencing shall remain in place throughout all phases of construction. Fencing shall not be removed until all construction equipment has left the site and written approval is granted by the director.
g. Exceptions may be granted to allow access to the site and work area, with specific conditions established by the director.
h. The storage of equipment, materials, debris, or fill shall not be allowed within the enclosure of the tree preservation fencing.
i. The applicant shall submit, in writing to the director, a verification that all required tree preservation fencing and required preservation measures have been completed. The director shall inspect and approve this verification, within three business days, prior to the issuance of any permits.
(3) Natural groundcover, especially woody vegetation, shall be used to the extent that is practicable, as it is most effective in holding soil in place and preventing site erosion. Adaptability to local conditions without the use of harmful fertilizers or pesticides, and the ability to filter runoff, make the use of indigenous vegetation preferable to non-indigenous plantings.
(4) Land development shall minimize impervious cover associated with the proposed use or development. Keeping impervious cover to a minimum enhances rainwater infiltration and effectively reduces stormwater runoff potential.?

B. Site screening requirement B. A ten-foot wide landscaped planting strip shall include street-type shade trees, measuring from two to 2? inches in caliper, planted at intervals of 30 to 40 feet. In addition, a combination of large shrubs, small shrubs, and groundcover (not to include turf grass), arranged formally or informally, that will cover the entire area at maturity shall be required. Groundcover shall not comprise more than 15 percent of the site screen area. Large shrubs shall measure at least 30 inches in height at the time of planting and reach a minimum mature height of 3? feet. Small shrubs shall measure at least 18 inches in height at the time of planting and reach a maximum of 3? feet at maturity. Enough large shrubs must be planted to maintain a visual buffer the length of the site screen area. In addition to this vegetation, a screening element of at least six feet in height must be created to consist of either a masonry wall, a combined three foot high earthen berm with the required landscaping located atop the berm, or a solid wood fence. All species must be approved by the city arborist.
C. Site screening requirement C.
1. A seven-foot-wide landscaped planting strip shall include evergreen trees planted at intervals of six to ten feet, measuring a minimum of six feet in height at the time of planting and reaching a minimum height of 12 feet at maturity. In addition to this vegetation, a screening element of at least six feet in height must be created to consist of either a masonry wall or a solid wood fence. All species must be approved by the city arborist.
2. Requirements A, B, and C are standards for the size and site screening area and the density and type of landscaping/planting. The developer may substitute a higher site screening requirement, requirement C being higher than B, and B being higher than A. In certain situations, as designated in the table in this subsection, either site screening requirement B or C may be used. Existing trees and other vegetation may be used for site screening, if they are healthy and are approved as part of the landscaping plan by the city arborist. All site screening required by this section must be installed prior to the occupancy of the use. Where compliance with this regulation is not possible because of seasonal planting limitations, the city arborist shall grant an appropriate delay.

To accomplish this goal, the following information shall be included in the concept plan:
?
(iv) Existing Tree and Vegetation Plan. The plan shall include the following for the entire project area:
(A) The outline of existing masses of vegetation. Forested areas shall be separately identified.
(B) Description of Existing Conditions. A narrative shall describe the quality of the existing vegetation and the impacts of the development on the vegetation.
(C) Description of Preservation Strategies. A narrative shall be provided to describe strategies for preservation and protection of existing vegetation to remain.

Title 13 ENVIRONMENT
Chapter 13.12 RIPARIAN BUFFERS
13.12.030 Management of a riparian buffer.
Each riparian buffer required to be established or maintained pursuant to Division I of this title shall be managed as part of the stormwater facility management agreement and as provided herein:
(1) The target vegetative cover in a riparian buffer area shall be an indigenous riparian forest with ground cover, shrub and tree canopy layers.
(2) Within 25 feet of the top of the state waters bank and land classified as wetlands:
(a) Indigenous riparian vegetation shall be preserved, or, where it does not exist, it shall be restored or allowed to evolve by natural succession;
(b) Dead, diseased, and dying trees may be removed;
? Fallen trees that are blocking stream channels, or trees with undermined root systems in imminent danger of falling, may be removed where stream bank erosion is a current or potential problem that outweighs any positive effects the fallen tree or trees may have on the stream ecosystem;
(d) Removal or pruning of invasive shrub and vine species is allowed; provided, that such removal or pruning is done in a manner that prevents erosion;
? Unpaved pathways and trails may be constructed and maintained in a manner that will effectively control erosion and minimize adverse impacts to the buffer, subject to applicable provisions of SCC 13.12.050; and
(f) Stormwater channels may be constructed and maintained in a manner that will prevent erosion and minimize adverse impacts to the buffer.
(3) Beyond 25 feet from the top of the public waterway bank to the limits of the required buffer:
(a) Dead, diseased and dying trees may be removed;
(b) Trees six inches in diameter or greater, measured 48 inches from the ground, shall be preserved;
? Removal or pruning of invasive shrub and vine species shall be allowed; provided, that such removal or pruning is done in a manner that prevents erosion;
(d) Unpaved pathways and trails may be constructed and maintained in a manner that will effectively control erosion and minimize adverse impacts to the buffer, subject to applicable provisions of SCC 13.12.050; and
? Stormwater channels may be constructed and maintained in a manner that will prevent erosion and minimize adverse impacts to the buffer.
(4) Where an existing structure (i.e., building, street, road, bridge, etc.) is located within the buffer, vegetation, not including the ground cover, can be removed within 15 feet of the structure. Removal of additional vegetation can be allowed if required by state or federal requirements or if necessary for the health, safety or welfare of the city?s citizens and approved by the administrator.
