Pavement Design Overview

• Soil classification within the Lake Mathews project area

• Flexible pavement design

• Rigid pavement design

• Final selection for pavement design

61

Soil Classification

• USDA classification of soils was found using Web Soil Survey v2.0.

• CBR value was found using FAA standards.

• A CBR value of four was selected.

Flexible Pavement Design

• Due to the gross weight of our service aircraft (Less than12,500 pounds) our design was based on light weight aircraft criteria.

• FAA specifies that no reduction in thickness should be made for “noncritical” areas of pavement (i.e. Apron).

63

Results of Flexible Pavement Design

Hot Mix Asphalt Surface: Four inches

Structural Base: Three inches

Subbase: Nine inches

Subgrade Compaction: 90% for Four to Eight inches

References: Federal Aviation Administration: AC 150-5320-6D, Chapter 5 Pavements for light aircraft.

64

Flexible Pavement Detail

65

Rigid Pavement Design

• Subbase: Is required due to the soil type CH located within our runway.

• Subgrade: 90% compaction required for soil types found within our project site.

• Jointing: Not to exceed maximum spacing.

66

Results for Rigid Pavement Design

Portland Cement Concrete: 5 inches

Subbase: 5 inches

Subgrade: 90 % compaction

Joint spacing: See

Selection of Pavement

Flexible pavement was selected for the Lake Mathews Municipal Airport due to construction costs and timeline.

Grading

Kristin Taylor

Grading Plan Overview

• Grading of runway and taxiway

• Grading of non-critical areas

• Final grading plan

• Earthwork

71

Runway & Taxiway Specifications

72

Runway Cross Section

73

Grading of Non-Critical Areas

• Access Road – 2% from the center line to the gutters on either side.

• Perimeter Road – 2% away from runway and taxiway.

• Apron – Design to allow surface flow of 1% away from the taxiway to the south edge of the apron area, where the water is treated.

• Structures – For buildings and other structures a 2% grade for a minimum of 10 feet was used.

74

Summary: Based on the designed grading plan a net cut of 24,965 cubic yards will need to be removed from the project site.

Airport Drainage

Sean Hoss

77

Drainage

• Promotes safe and efficient operations

• Handles airport surface runoff

• Diverts runoff away from Lake Mathews

• Two drainage areas– Runway handled by Volume Based drainage– Ramp area handled by Flow Based drainage

• Based on Riverside County Flood Control District BMP Handbook

78

Runway Runoff

• Corrugated steel pipe– Slope = 0.005

– Di = 15”, Df = 24”

– Inlets at 400 feet or less– Water quality inlet

• Ponding – Rainfall > 0.85 in/hr– 10 acre-ft storage

• Outfall– Extended detention basin

79

Ramp Runoff

• Filter strip (turf grass)– 15’ depth– Wide as the ramp– Removes pollutants

and sediment

• Infiltration trench– Aggregate 1-3”– 48 hr drawdown– Overflow pipe to

detention basinSource: RCFCD BMP Handbook

Environmental Impact Assessment

Denise Chow

81

Environmental Noise Impact• Environmental Concerns

• With restrictions in time, we will concentrate on noise impact

• INM: Integrated Noise Model

– FAA approved Airport Noise Exposure Map

– Noise contours generated with real-time values and coordinates

• General allowable threshold

– FAA (Advisory Circular) 65 dB

– 7 different thresholds of noise level

Importing Supplemental Data

• CAD graphics– Airport runway layout– AutoCAD DXF file for graphic enhancement

• Terrain data– Topographic map overlay– Signify elevation affecting noise propagation

• Street census– Streets, highways, hydrographic features, civil boundaries– Overlays street map data

• Population census– Population points– Enables visual inspection of sound impact on neighboring residents

Outcome

• Viable source for current and future noise predictions generated by Lake Matthews Airport (LMA) and its components

• Ensure LMA from causing unwanted noise around neighboring communities– Homes, schools,

businesses– Easement required
