In the development or use of an open lot, where an existing structure is also being demolished, a party or foundation wall may be exposed. This may affect the structural stability of the adjoining structure(s) or a retaining wall due to the removal of lateral supports, exposure to the weather, new loads on the adjacent ground, etc. This would warrant requiring a licensed architect or engineer to make an evaluation of such wall(s) or other conditions and provide design details to counter possibility of any unsafe condition.
According to the above referenced '30-02 and more specifically paragraph (a)(2) which states "An application for or including an open parking lot shall be accompanied by a plan showing: ... (iv) the nature of the walls of adjoining structures, if any, i.e., whether masonry, frame, metal, etc.; (v) retaining walls to be built; (vi) retaining walls and open spaces, if any, on adjoining premises;..."
To address these requirements, the application and plans submitted by a licensed professional shall include:
- A description of the existing condition of the walls, along with an assessment of their structural stability, predicated on the potential maximum load that could be imposed on the ground adjacent to the wall.
- Structural drawings and details of any retaining walls to be built for such development.
Plan examiners shall verify inclusion of such drawings, details and notes. For applications filed under self-certification, the audit shall confirm inclusion of such information, details and notes.
Applications filed without this information shall not be accepted or approved.
