The first thing you need to do is to figure out how you want the array to be formatted. I can see 2 ways to do this.

// array format 1
$rows = array(
  'url' => 'value from url field',
  'codes' => array(
    // array of codes
    'code 1',
    'code 2'
  )
}

to get the above

$target_urls = array();
if (have_rows('target_urls', 'options')) {
  while (have_rows('target_urls', 'options')) {
    the_row();
    $url = get_sub_field('single_url');
    $codes = array();
    if (have_rows('site_codes')) {
      while (have_rows('site_codes')) {
        the_row();
        $codes[] = get_sub_field('single_code');
      } // end while codes
      $target_urls[] = array(
        'url' => $url,
        'codes' => $codes
      );
    } // end if codes
  } // end while target urls
} // end if target_urls

// array format 2
$rows = array(
  // array key is the url
  'value of url field' => array(
    // array of codes
    'code 1',
    'code 2'
  )
)

to get the above

$target_urls = array();
if (have_rows('target_urls', 'options')) {
  while (have_rows('target_urls', 'options')) {
    the_row();
    $url = get_sub_field('single_url');
    $target_urls[$url] = array();
    if (have_rows('site_codes')) {
      while (have_rows('site_codes')) {
        the_row();
        $target_urls[$url][] = get_sub_field('single_code');
      } // end while codes
    } // end if codes
  } // end while target urls
} // end if target_urls
