MY LATE SON

This is David Rieff's second sentence in his essay "After 9/11":

"Designed by the architect Michael Arad and the landscape architect Peter Walker and called "Reflecting Absence," the memorial will be about eight acres in size and consist of two sunken reflecting pools, each surrounded by an enormous waterfall, the largest manmade ones in North America, according to the memorial's official website."

"Designed by the architect Michael Arad and the landscape architect Peter Walker and called 'Reflecting Absence'" is a participial phrase with a compound verbal that modifies the subject of the main clause, "the memorial."
--"Designed" is a participle. It's half of the compound verbal.
--"by the architect Michael Arad and the landscape architect Peter Walker " is a prepositional phrase with a compound object of the preposition. This prepositional phrase functions as an adverb because it modifies "Designed."
--"and" is a conjunction that joins the two verbals in the participial phrase.
--"called 'Reflecting Absence'" is the other verbal, which has a direct object, "'Reflecting Absence."

"the memorial" is the subject of the sentence.

"will be" is half of the compound main verb. "will" is a modal that carries the present tense.

"about" might look like a preposition, but here I think it's an adverb. It's like the word "approximately" here.

"eight acres" is the subject complement, the predicate noun, to the main verb, "will be."

"in size" is a prepositional phrase that works as an adjective since it modifies "eight acres."

"and" is a conjunction that joins the compound main verbs.

"consist" is the other half of the main verb.

"of two sunken reflecting pools" is a prepositional phrase. Or maybe it's some kind of complement since nothing can just "consist." Some has to "consist of" something. Not sure here. "sunken" and "reflecting" are both participles that act as adjectives. "sunken" is a past participle and "reflecting" is a present one.

"each surrounded by an enormous waterfall" is an appositive phrase that modifies "pools." "each" is modified by the participle "surrounded," and "surrounded" is modified by the prepositional phrase "by an enormous waterfall." I am using the passive voice for good reason because, in this sentence analysis, what's more important are the things being affected--David Rieff's language--instead of the writer, the agent, David Rieff.

"the largest manmade ones in North America" is another appositive that modifies "waterfall." The thing, though, is that "waterfall" is singular and "ones" is plural, so it looks like there's an agreement problem. I am no expert, however, on any of this.

"according to the memorial's official website" is something. I want to say it's a participial phrase because of the "according," but I don't think that's right because "according" is one of those things that look like participles but aren't really attached to any specific noun. Instead, this is something that might be called an adjunct. It serves the purpose of orienting the reader toward something, but it's not really attached to a specific noun. It modifies an idea or something vague instead of something specific. This is the weakest phrase in the sentence, so it's not a good idea to end on it. And "website" is a boring word, so it's not good to end with such a word.
