Statement of Work (SOW)

Bldg 620 Retrofit Channel/Infiltration Swale

Project Description: The project purpose is to retrofit an existing concrete channel that runs between Bldgs 619, 620, and 622 with an infiltration swale and provide other landscaping improvements to promote storm water infiltration, improve water quality, and prevent flooding and runoff.

1. General:

1.1 Description of Services: The Contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items necessary to retrofit an existing concrete channel that runs between Buildings 619, 620, and 622 on the Presidio of Monterey. This includes, but is not limited to: removing the existing concrete v-ditch, installing a cobble-lined infiltration swale with surrounding native riparian vegetation and improving the existing outdoor gathering area with permeable paving, vegetation, and seating areas. The contractor shall perform to the standards in this contract and all work shall be in compliance with the current editions of all applicable codes and standards.

1.2 Background: The existing concrete channel that runs between Bldgs 619, 620, and 622 does not effectively capture and divert storm water runoff, and instead collects and pools near the sidewalk around Bldg 620. During heavy rain events, the sidewalk becomes flooded, creating a nuisance for the building’s occupants. It also presents a hazard as people may be forced to walk in the street instead of the sidewalk.

1.3 Objectives: The primary objectives of this requirement are to mitigate sidewalk flooding at Bldg 620, and to reduce the quantity of stormwater runoff and provide water quality benefits in compliance with the NPDES General Permit for Phase II Small Municipal Separate Storm Sewer Systems (MS4).

2. Scope of Work:

2.1 The contractor shall provide labor, material, equipment, transportation, and project management to execute and complete the subject project. Work requirements include, but are not limited to, the following:

General

a. Contractor shall be responsible to provide necessary geotechnical engineering and survey data, and coordinate and provide design and engineering services for removal and disposal of the existing concrete channel, and installation of the swale, surrounding landscaping, and seating areas.

A SWPPP is required to be developed prior to construction of projects that disturb one acre or more to address the control of pollutant discharges using BMPs selected for the specific project and to address stormwater monitoring. The BMPs would include but not be limited to the following:

• Schedule construction sequences to minimize land disturbance during rainy and dry seasons

• Provide soil stabilization to steep slope areas

• Provide sediment controls to intercept and slow down stormwater flows

• Cover stockpiled soil

• Use dust suppressants, such as watering soils and unpaved roadways

• Preserve existing vegetation where no construction activities are berms, fiber rolls, sediment traps, erosion control blankets, check dams in medium-sized channels, or straw bale dikes in smaller drain channels

• Cover stockpiled soil

• Use dust suppressants, such as watering soils and unpaved roadways

• Preserve existing vegetation where no construction activities are planned and wherever possible

• Replant/revegetate all exposed disturbed areas with POM approved seed immediately upon completion of construction with POM approved plants

Following the completion of each Project or Concept located in an undeveloped area or on steep slopes but that disturbs less than one acre, post-construction BMPs and long-term maintenance plans shall be implemented.

Programmatic Environmental Assessment 25

Resource Impact Alternative 1, Proposed Action Alternative 2, No

Action Alternative 3, Full Implementation

Measures Incorporated into the Proposed Action

Mitigation Measures during construction would include noise from large equipment at each of the construction Projects and Concepts.

noise measures shall be implemented for all Projects and Concepts:

• The construction contractor shall ensure that all equipment has the manufacturers’ recommended noise abatement measures, such as mufflers, engine enclosures, and engine vibration isolators, intact and operational. Further, all construction equipment shall be inspected at periodic intervals to ensure proper maintenance and presence of noise control devices.

• Construction activities shall be limited to daytime hours (8:00 a.m. to 5:00 p.m.). In addition, the POM currently promotes quiet hours during the normal workweek for some Construction Projects.

This could include quiet hours between 6:00 a.m. and 10:00 a.m. on specific workdays, if requested by affected staff.

Local neighborhoods shall be notified of the project, and signage should be posted that provides a phone number to call to register complaints about construction-related noise problems.

Operational noise Less than Significant No Impact Less than Significant None identified. None required.

Mitigation Measures would not be expected to measurably change from baseline conditions.

Public Health and Safety

Adverse effects to public health and safety could occur if treated greywater and stormwater does not meet appropriate water quality standards.

No Impact Less than Significant with Mitigation

None identified. Mitigation Measure PHS-1:

Treated water shall meet the higher of NSF 350 or CA Title 22 standards (or most recent higher standard) for recycled water systems.

Utilities

The improvements to stormwater infrastructure on the POM would result in long-term benefits to both on-site and downstream stormwater facilities as the quantity of stormwater runoff would be reduced, which would reduce future demands on existing stormwater conveyance capacity.

Beneficial Effect No Impact Beneficial Effect None identified. None required.

Visual Resources

Mitigation Measures long-term adverse effects on visual resources.

Long term visual effects from bioswale projects and concepts would improve the visual character of the surrounding areas.

Beneficial Effect No Impact Beneficial Effect None identified. None identified.

Water Resources

Construction activities would result in ground disturbance that could lead to erosion and subsequent sedimentation of downstream waterbodies following a storm event.

Stormwater Measure 1:

Compliance with General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities (Order No. 2010-0014-DWQ).

In compliance with the General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities (Order No. 2012- 0006-DWQ), appropriate Best Management Practices (BMP) would be implemented during construction that would minimize impacts on water quality. BMPs may include, but would not be limited to:

scheduling construction to avoid the rainy season;

applying mulch, soil binders, or hydroseeding; installing earth dikes, berms, check

Mitigation Measure GS-1 (refer to Geology and Soils above)

Resource Impact Alternative 1, Proposed Action Alternative 2, No

Action Alternative 3, Full Implementation

Measures Incorporated into the Proposed Action

Mitigation Measures dams, straw bales, or other velocity dissipation devices;

protecting storm drain inlets with gravel bags, fiber bags, fiber rolls, or other filtration devices; stabilizing streambanks and hillslopes;

installing silt fences; installing sediment basins; or increasing the frequency of street sweeping.

Implementation of one or more of these BMPs or other similar BMPs would ensure that there is minimal suspended sediment in runoff that discharges into storm drains and eventually to the Monterey Bay. For Construction Projects and Concepts that would disturb more than one acre of land, a stormwater pollution prevention plan (SWPPP) and coverage under the California stormwater construction general permit would be required.

Adverse effects to water quality could occur if treated greywater and stormwater does not meet appropriate water quality standards.
