Please label plot plan with the total impervious surface details and overall property size.

DE C&O #01 Eng Plans – FDP/PDP

All required engineering plans and studies, including water lines, sanitary sewers, storm drainage, streets and erosion and sediment control shall be submitted along with the final development plan. All public infrastructure must be substantially complete, prior to the issuance of any certificates of occupancy.

DE C&O #02 Master Drainage Plan

A Master Drainage Plan (MDP) shall be submitted and approved in accordance with the City’s Design and Construction Manual for all areas of the development, including all surrounding impacted areas, along with the engineering plans for the development. The MDP shall address drainage level of service issues on an individual lot basis, including the swale shown adjacent to the pool house ADU.

DE C&O #03 Eng & Insp Fees

All Engineering Plan Review and Inspection Fees shall be paid prior to approval of the associated engineering plans and prior to the issuance of any site development permits or the start of construction (excluding land disturbance permit).

DE C&O #05 As-Graded MDP

The As-graded Master Drainage Plan shall be submitted to and accepted by the City prior to the issuance of a Certificate of Substantial Completion and prior to the issuance of any building permits for the development.

DE C&O #06 Land Disturbance

A Land Disturbance Permit shall be obtained from the City if groundbreaking will take place prior to the issuance of a site development permit, building permit, or prior to the approval of the Final Development Plan / Engineering Plans.

Please label plot plan with the total impervious surface details and overall property size.

Retaining walls appear to be very close to existing easements. Upon review of the raster image, it appears a portion of at least one retaining wall is within the eawement. Please be aware that footings, tie-back geogrid, underdrains, or any other feature connected to the retaining wall cannot be contained wholly or partially within the existing easement. Please evaluate and revise as appropriate to ensure all retaining wall elements are outside the easement.

The building corner appears to be within the existing utility easement. It is difficult to judge, however, since the raster image does not scale-up upon zooming-in. Please evaluate and revise to ensure all building corners and footings are outside the limits of utility easements.

Prior to approval of any Final Development Plan, a drainage study shall be required. This drainage study shall present calculations of the drainage area directed toward the proposed swale, and the depth of flow within the swale along key points along the swale. The drainage study shall be prepared by a design professional registered in the State of Missouri.

A minimum of 2.0 feet of freeboard between the top of the swale and the 100 year hydraulic grade line within the swale shall be established. This is required to ensure the structure is protected from flooding. Please ensure this is addressed in the drainage study.

The horizontal limits of the water surface within the swale shall be a minimum of 3 feet from the west property line. This shall be calculated for the 100 year event, and preliminary estimate shown on the plan. Please update the plan to show the location of the estimated 100 year water surface elevation within the swale along the west property line, along with dimensions from this line to the property line. This estimate shall be re-evaluated during the Final Development Plan process.
