QUESTIONS AND ANSWERS

Solicitation Amendment Attachment Subject

140P5426Q0032 0001 0003 Questions and Answers

The following questions were received in response to the solicitation. The Government's answers clarify the solicitation and Statement of Work (SOW). Offerors shall consider these responses when preparing quotations. Except as revised by Amendment 0001, all other terms and conditions remain unchanged.

Question 1 - Clarification on Numerical Clearance Distances Question: SOW Section 6, Paragraph 21 states that where a numerical clearance is not explicitly defined for buildings, signs, lights, docks, or access points, the Contractor must prune to provide practical operating clearance. To ensure pricing consistency and eliminate performance disputes, could the Government establish specific minimum numerical clearance distances (for example, 3 feet from buildings and 5 feet from light fixtures) required for each structure type?

Government Response

The following approximate clearances establish consistent pricing and general performance expectations:

Buildings and structures: Maintain approximately 3 feet of clearance from exterior walls, rooflines, gutters, eaves, and other building components. Vegetation shall not remain in direct contact with the structure.

Signs: Maintain approximately 3 feet of clearance around signs and sign supports while ensuring that the entire sign face remains clearly visible from the intended approach.

Light fixtures: Maintain approximately 5 feet of clearance from light fixtures and ensure vegetation does not obstruct the intended illumination area.

Docks and boardwalks: Maintain approximately 3 feet of lateral clearance from railings, walking surfaces, and structural components, with a minimum vertical pedestrian clearance of approximately 8 feet above walking surfaces where practicable.

Pedestrian access points: Maintain approximately 3 feet of lateral clearance and approximately 8 feet of vertical clearance.

Vehicular and service access areas: Maintain sufficient lateral clearance to prevent vegetation from contacting vehicles and approximately 14 feet of vertical clearance where vehicular access is required.

Attachment 0003 | Amendment 0001 | 140P5426Q0032 | Page 2 of 4

These distances do not authorize excessive or improper pruning. Where species characteristics, environmental requirements, mangrove regulations, or accepted arboricultural practices prevent the specified clearance from being achieved without damaging the vegetation, the Contractor shall notify the COR before proceeding. The COR may approve an adjusted clearance based on field conditions.

Question 2 - Shoreline Height Reduction Baseline - Area 5 Question: SOW Section 7, Area 5 (Boardwalk/VC Docks) requires the Contractor to reduce the existing overall shoreline vegetation height by approximately 25 percent, measured from the pre-work average height of each continuous treatment section. Could the Government clarify how the baseline pre-work average height will be measured and agreed upon prior to cutting, and whether the Park currently possesses an established baseline canopy survey for these sections?

Government Response

The approximately 25-percent reduction will not be based on a formal surveyed canopy elevation for every individual tree or plant.

Before pruning begins within each continuous shoreline treatment section, the Contractor's qualified arborist/Professional Mangrove Trimmer and the COR will jointly review the existing vegetation and establish a representative pre-work average height for that section.

Representative measurements will be taken at multiple locations within each continuous treatment section and documented through measurements and pre-work photographs. The agreed representative average will serve as the baseline for determining the approximate 25-percent reduction.

The 25-percent requirement applies to the overall average vegetation height of the treatment section. It does not require an exact 25-percent reduction of every individual tree or stem.

The Park does not currently intend to provide a separate surveyed canopy baseline. The Contractor shall include the field verification and documentation necessary to establish the pre-work condition as part of its work.

All reductions remain subject to applicable mangrove-trimming requirements and accepted arboricultural practices. If achieving a 25-percent height reduction would conflict with applicable regulatory requirements or result in excessive defoliation or damage, the regulatory and arboricultural limitation shall govern, and the Contractor shall coordinate with the COR before proceeding.

Question 3 - Mangrove Pruning Permitting Requirements Question: SOW Section 13 and SOW Section 7 (specifically Areas 3, 5, 6, and 7) require compliance with mangrove-trimming regulations and Florida's Professional Mangrove Trimmer (PMT) qualifications. Is the Contractor required to obtain or pay for any environmental permits (such as from the State of Florida or Miami-Dade County) to execute this maintenance pruning, or does the National Park Service operate under an existing maintenance permit or Federal supremacy exemption?

Government Response

The Contractor shall comply with all applicable Federal, State, and local requirements governing mangrove trimming and shall ensure that mangrove-related work is performed or supervised by individuals meeting the applicable Professional Mangrove Trimmer qualification and registration requirements.

Attachment 0003 | Amendment 0001 | 140P5426Q0032 | Page 3 of 4

The Government will be responsible for determining whether a project-specific environmental permit, exemption, notification, or other regulatory authorization is required for the work described in the SOW and will coordinate any Government/property-owner authorization determined necessary before the affected work begins.

Unless otherwise provided through an amendment to the solicitation, offerors should not include environmental permit application fees in their base proposal.

The Contractor remains responsible for the cost of maintaining its own professional certifications, licenses, registrations, and qualifications necessary to perform the work.

No mangrove trimming shall begin until the COR confirms that the applicable environmental requirements for the affected work area have been satisfied. Nothing in the SOW authorizes mangrove removal or pruning beyond the limits permitted by applicable requirements.

Question 4 - Heavy Equipment Storage and Overnight Staging Question: SOW Section 5, Paragraph 10 states that staging, equipment, and vehicle storage will be confined to locations designated by the COR. SOW Section 5, Paragraph 11 requires daily removal of all Contractor-generated debris. Will the Contractor be permitted to stage heavy operational equipment (such as wood chippers, aerial lifts, and dump trailers) overnight in the designated staging area or Maintenance Yard (Area 2) for the duration of the 30-calendar-day performance period, or must all equipment be demobilized off-site at the end of each workday?

Government Response

Yes. Subject to prior approval by the COR, the Contractor may stage heavy operational equipment such as wood chippers, aerial lifts, trailers, and similar equipment overnight within the designated staging area or Maintenance Yard for the duration of the contract performance period.

The Contractor will remain responsible for securing its equipment and protecting Government property.

Equipment shall be staged only in locations designated by the COR and shall not obstruct Government operations, emergency access, public access, or employee parking or access requirements.

Equipment shall be maintained in a condition that prevents fuel, hydraulic fluid, oil, or other contaminants from being released onto Government property. Fuel, chemicals, or other regulated materials shall not be stored onsite unless specifically approved by the COR and stored in accordance with applicable requirements.

The requirement for daily removal applies to Contractor-generated vegetative debris, waste, and similar materials. It does not require daily demobilization of approved operational equipment.

Question 5 - Mitigation Protocol for Severely Damaged or Dead Trees Question: The solicitation and SOW state that the base contract covers pruning/trimming and excludes whole-tree removals. If the physical inspection by the Contractor's ISA Certified Arborist identifies a tree within the nine mapped work areas that is dead, structurally compromised, or represents an immediate safety hazard that cannot be mitigated by pruning alone, what protocol should the Contractor follow?

Will the Government establish an optional/add-on CLIN for emergency tree removals, or will these be handled through post-award contract modifications?

Government Response

Whole-tree removal is not included within the current base scope of work.

If the Contractor's ISA Certified Arborist determines that a tree is dead, structurally compromised, or presents an immediate safety concern that cannot reasonably be mitigated through the pruning activities authorized by the SOW, the Contractor shall:

Stop work on the affected tree before performing work beyond the authorized pruning scope.

Immediately notify the COR.

Document the condition with photographs and provide the arborist's recommendation regarding the identified hazard.

Establish a temporary safety perimeter or otherwise secure the immediate work area when necessary to protect employees, visitors, and Government property.

Await Government direction before performing any whole-tree removal.

The Contractor shall not remove a whole tree without written authorization from the Contracting Officer.

If the Government determines that removal is necessary, the work will be addressed separately through an appropriate contract action, such as a contract modification or other authorized procurement method. Unless specifically added to the solicitation by amendment, offerors should not include whole-tree removal costs in the base contract price.
