The OPC <br />recommends using the projections included in Figure 5, below. Low-risk projections should be used for short-lived <br />infrastructure that is readily adaptable, such as trails. Medium -risk projections should be used for less adaptive, <br />more vulnerable projects such as housing developments. Extreme risk projections should be used for larger and <br />more complex infrastructure projects such as roads, wastewater treatment plants, and hazardous waste sites. <br />Figure 5: San Francisco 2018 Probabilistic Sea -Level Rise Projections28 <br />a <br />o-� <br />10 <br />W <br />a B <br />m <br />Z LOW RISK °P <br />} 'a <br />W MEDIUM RISK <br />J <br />a EXTREME RISK u <br />W m w <br />w jy <br />LL <br />4 � <br />✓1 r0 W � <br />Sn � <br />h] Y ! <br />Ii l:i E�1 it 1 1 <br />2030 2040 2058 2680 24T0 2480 2094 2140 <br />'Probabilistic -based projections "associate a likelihood of occurrence (or probability) with sea -level rise heights and rates and are directly tied <br />to a range of emissions scenarios."18 <br />City of Redwood City Climate Action Plan Y7 <br />
