Question: Orlando Pleasant Shields Plummer moved to a city that covers how many square miles?

<P0-S0> Orlando Pleasant Shields Plummer (April 13, 1836 – December 7, 1913) was an American physician and politician in the state of Oregon. <P0-S1>  A native of Pennsylvania, he started practicing medicine in Illinois before moving to Portland, Oregon. <P0-S2>  In Oregon, he continued his medical work as well as working for several telegraph companies. <P0-S3>  A Republican, Plummer was also a member of the Oregon Legislative Assembly, a medical professor, fruit farmer, and Portland city council member. <P0-S4>  His drug store in downtown had the first telephone in Portland. <SEP> <P1-S0> Laguna Beach State Marine Reserve (SMR) and Laguna Beach State Marine Conservation Area (SMCA) are two adjoining marine protected areas that extend offshore of Laguna Beach in Orange County on California’s south coast. <P1-S1>  The SMR covers 6.27 square miles, and the SMCA covers an additional 3.44 square miles. <P1-S2>  These two MPAs are part of a four-MPA complex on the coast of southern Orange County. <P1-S3>  Each protects marine life by prohibiting or limiting the removal of marine wildlife from within its borders. <SEP> <P2-S0> Chippewa Moraine Lakes is a Wisconsin Department of Natural Resources-designated State Natural Area that comprises nine separate sites, spread out over roughly 30 square miles (78 km). <P2-S1>  Each site features a primarily undisturbed lake located within the rough terminal moraine topography of northern Chippewa County. <P2-S2>  Each lake has its own unique species assemblage due to physical and chemical characteristics of the lake. <P2-S3>  The nine lakes are: Camp Lake, a 6-acre (2.4 ha) lake ringed by a floating sphagnum bog mat containing such plant species as white beak rush, narrow-leaved sundew, small cranberry, and grass pink orchid. <P2-S4>  Spence Lake, a 12-acre (4.9 ha), acidic bog lake that is the headwaters of Foster Creek. <P2-S5>  Conifer swamp surrounds the northern part of the lake, hardwood swamp surrounds the central part, while the southern part is largely a sedge meadow, impacted by beaver activity. <P2-S6>  Bass Lake #1, a 6-acre (2.4 ha) soft-water seepage lake, with at least one rare plant species present. <P2-S7>  Bass Lake #5, an 8-acre (3.2 ha), deep, hard-water seepage lake that is the main headwaters branch of Mud Creek. <P2-S8>  Deer Lake, a 6-acre (2.4 ha) seepage lake that is also part of the headwaters of Mud Creek. <P2-S9>  Burnt Wagon Lake, a 15-acre (6.1 ha) softwater seepage lake that is landlocked, with no development. <P2-S10>  Fishpole Lake, an 11-acre (4.5 ha) meromictic lake. <P2-S11>  Due to its size, shape, and depth, the lake's water column is permanently thermally stratified, unlike most Wisconsin lakes, leading to unique chemical and biological characteristics. <P2-S12>  Plummer Lake, a 41-acre (16.6 ha), deep, hard-water seepage lake. <P2-S13>  Little Plummer Lake, a 10-acre (4 ha) wild (no access roads or development) hardwater seepage lake that drains into Plummer Lake. <SEP> <P3-S0> Portland ( ) is the largest city in the U.S. state of Oregon and the seat of Multnomah County. <P3-S1>  It is a major port in the Willamette Valley region of the Pacific Northwest, at the confluence of the Willamette and Columbia Rivers. <P3-S2>  The city covers 145 sqmi and had an estimated population of 639,863 in 2016, making it the 26th most populous city in the United States. <P3-S3>  Approximately 2,424,955 people live in the Portland metropolitan statistical area (MSA), the 25th most populous MSA in the United States. <P3-S4>  Its Combined Statistical Area (CSA) ranks 18th with a population of 3,160,488. <P3-S5>  Roughly 60% of Oregon's population resides within the Portland metropolitan area.
