Code Statement

All issues pertaining to life safety and property protection from the hazards of fire, explosion or dangerous conditions in new and existing buildings, structures and premises, and to the safety to fire fighters and emergency responders during emergency operations, shall be in accordance with the 2018 International Fire Code.

LAND USE SCHEDULE. - Building Area (sq. ft.). Please clarify the proposed building square footage. The listed building area of 20,130 sq. ft. appears to be for the building footprint, but it appears from the floor plan on Sheet A1.1 that there is mezzanine or similar second story space above the office area. The listed building area needs to reflect the gross floor area. Provide a breakdown of the ground floor space, second story space and total building area. - Floor Area Ratio. Revise the FAR to reflect any changes to the gross floor area based on comment above.

PARKING. Provide supporting information from other locations (e.g. parking surveys) or industry standards demonstrating that the number of parking spaces provided for the proposed use and square footage is sufficient to satisfy the expected parking demand

Revise the accuracy of the note that describes how the sump of the proposed BFPD will be drained. Illustrating this information on the WAT-12 construction standard detail is also acceptable.

Revise the overlapping texts located in the title block of sheet C3.4.

DIMENSION PLAN. Provide a dimension plan for the site in order for staff to verify that minimum standards such as drive aisle widths, parking space dimensions, building setbacks, etc. The FDP response letter indicates that this item is addressed by the following: "Please see Architectural sheets". However, no new architectural sheets were uploaded for review.

LAND USE SCHEDULE. Provide a table that includes the following information: - Site Area (sq. ft.) - Building Area (sq. ft.) - Floor Area Ratio - # of Required and Proposed Parking Spaces - Impervious Coverage (sq. ft. and % of site) - Open Space The FDP response letter indicates that this item is addressed by the following: "Please see Architectural sheets". However, no new architectural sheets were uploaded for review.

LIGHTING. Provide manufacturer specifications for all proposed pole light fixtures and wallpacks for review. The FDP response letter indicates that this item is addressed by the following: "Please see Lighting sheets". However, no new lighting sheets were uploaded for review.

EXTERIOR MATERIAL. Provide a spec sheet for the proposed textured metal panel to be used on the building. The FDP response letter indicates that this item is addressed by the following: "Please see Architectural sheets". However, no new architectural sheets were uploaded for review.

Provide a 0.5’ minimum drop in flowline elevation between the incoming 18” pipe (S) and the outgoing 18” pipe (E) within storm structure 2-2.

The City requires a 6-inch minimum layer of aggregate backfill below the bottom of the pipe. Show it in the trenching and backfill detail.

The sump of the fire backflow prevention device can be drained through the means of an infiltration gallery (filled with clean rocks), a daylight discharge or a connection to an existing storm structure. Select the most suitable option. Both the daylight and the storm structure connection can be made by gravitational flow or pressurized flow (sump pump).

Include the revised landscaping sheet(s) with the civil set of plans.

Please provide a stormwater memorandum that discusses how the runoff from the D-Bat project site will be managed.

In the SWPPP report, discuss the presence of endangered species or critical natural habitat. Make sure to revise the address and the project name shown as well. The scope of work shown in the SWPPP and on the civil plans must match.

Update the Engineer’s Opinion of Probable Construction Cost (EOOPCC) sheet. Add a private sanitary, an ESC and a site preparation (clearing + grading) section. Also, revise the quantity for concrete pavement, aggregate base and precast curb inlet. Remove the water meter cost item too, since that one will be inserted in the fee worksheet separately with the tap fee.

Throughout the set of plans, add the sheet title in the title block as shown in the sheet index.

Throughout the set of plans, revise the information shown in the title block as applicable. The project name and address shown do not refer to the D-Bat project location.

Revise the 1st general note shown on sheet C1.0 to state that “All construction, including the work done in the right of way, shall follow the City of Lee’s Summit’s Design and Construction manual”.

Revise the 4th general note shown on sheet C1.1 to state that “All construction shall follow the City of Lee’s Summit’s Design and Construction manual”.

Add a note or revise the concrete pavement section to show aggregate base + subgrade extending 1’ beyond back of curb.

Should perimeter stone be added by the sanitary lateral connection point as well in order to keep consistency around the building?

On sheet C1.2, show how far the proposed retaining wall with handrail is supposed to extend along the west side of the building.

Provide/include a construction detail for the proposed retaining wall(s).

Connection of proposed 6” fire line to existing 12” water main must be via a 12” x 6” cut-in tee, while connection of proposed 4" sanitary sewer lateral to public 10" sanitary main must be via a 10" x 4" cut-in wye.

Sidewalk construction must not exceed an 2% cross-slope and an 8.33% running slope. Therefore, it is recommended that the sidewalks be designed to include construction tolerances, which respectively refer to design slopes of 1.5% and 7.5%. Revise/include this information within the ADA note shown throughout the set of plans. Also, make sure that the sidewalk details shown on sheet C2.4 meet this ADA sidewalk requirement.

The 100-year hydraulic grade line runs way above the crown of pipe and appears to be too close to the throat of curb inlets. APWA Section 5600 requires a minimum clearance of 0.5 feet below any openings to the ground. Therefore, private storm line 3 may need to be upsized in order to meet this APWA storm requirement.

Provide a 0.5’ minimum drop in flowline elevation within every storm structure where the angle between the incoming and outgoing pipe is above 22.5 degrees.

We acknowledge that storm structure 2-2 and commercial entrances, as per the Mega Storage building permit, will need to be built prior to construction of private storm line 3 and the concrete parking lot. Otherwise, the construction of those pre-infrastructures would become the responsibility of the applicant for the current FDP project.

Include a trenching an backfill detail. The City requires a 12-inch thick layer of aggregate backfill over the top of utility pipe.

Only ornamental tree varieties are allowed within public easements. A 5’ minimum setback is also necessary from edge of existing public utility to edge of proposed overstory tree. Review and verify that the landscaping plan meets those requirements.
