504 Lot Construction – Above Green

Intent

Environmental impact during construction is avoided to the extent possible; impacts that do occur are minimized and any significant impacts are mitigated.

504.1 - On-Site Supervision and Coordination

(4 points)

On-site supervision and coordination is provided during on-the-lot clearing, grading, trenching, paving, and installation of utilities to ensure that specified green development practices are implemented. (also see Section 503.3)

Note: Points must be taken in 503.3 to claim points in 504.1.

504.2 - Trees and Vegetation

Designated trees and vegetation are preserved by one or more of the following:

Fencing or equivalent is installed to protect trees and other vegetation. (3 points)
Trenching, significant changes in grade, and compaction of soil and critical root zones in all “tree save” areas as shown on the lot plan are avoided. (5 points)
- Required Documentation: Landscape plan.
Damage to designated existing trees and vegetation is mitigated during construction through pruning, root pruning, fertilizing, and watering. (4 points)
- Required Documentation: Invoice or other evidence from qualified arborist.

504.3 - Soil Disturbance and Erosion Implementation

On-site soil disturbance and erosion are minimized by one or more of the following in accordance with the SWPPP or applicable plan: (also see Section 503.3)

Sediment and erosion controls are installed on the lot and maintained in accordance with the stormwater pollution prevention plan, where required. (5 points)
- Required Documentation: Storm water pollution prevention plan.
Limits of clearing and grading are staked out on the lot. (5 points)
“No disturbance” zones are created using fencing or flagging to protect vegetation and sensitive areas on the lot from construction activity. (5 points)
Topsoil from either the lot or the site development is stockpiled and stabilized for later use and used to establish landscape plantings on the lot. (5 points)
Soil compaction from construction equipment is reduced by distributing the weight of the equipment over a larger area (laying lightweight geogrids, mulch, chipped wood, plywood, OSB, metal plates, or other materials capable of weight distribution in the pathway of the equipment). (4 points)
Disturbed areas on the lot that are complete or to be left unworked for 21 days or more are stabilized within 14 days using methods as recommended by the EPA or in the approved SWPPP, where required. (3 points)
- Required Documentation: As-built construction schedule.
Soil is improved with organic amendments or mulch. (3 points)
- Required Documentation: Invoice or evidence from landscape contractor.
Utilities on the lot are installed using one or more alternative means (5 points):
- tunneling instead of trenching,
- use of smaller equipment,
- use of low ground pressure equipment,
- use of geomats,
- shared utility trenches or easements,
- other.
  - List "other" means of installing utilities: ________________
  - Required Documentation: Plans and scope of work showing alternative means used.
Inspection reports of stormwater best management practices are available. (3 points)
- Required Documentation: Inspection reports of stormwater best management practices.
