A quick glance at the Suffolk County legislative district map reveals that only one representative’s territory stretches all the way from the North to the South shore.

It’s a very narrow line, but at that one point, from Wading River to Center Moriches, one legislator represents residents from Long Island Sound to Moriches Bay.

That legislator is our very own representative, Ed Romaine, who lives in Center Moriches.

So for the past six-plus years, the North Fork has been represented in the county Legislature by a South Shore resident from Brookhaven Town.

This hasn’t been an issue … so far. Mr. Romaine has worked tirelessly since his 2006 swearing-in and has been an effective legislator for his entire district. He’s made land preservation and public transportation — important topics on the North Fork — two of his signature issues.

Mr. Romaine has done us good, and this newspaper has supported him with an endorsement in each of his four campaigns.

Now Mr. Romaine is considering a run for the soon-to-be vacant Brookhaven Town supervisor seat. If he receives his party’s nomination, he’ll have a good shot at beating likely Democratic nominee Brian Beedenbender.

What we fear is that the North Fork could soon be represented by someone with no real connection to this area; someone who wouldn’t work quite as hard as Mr. Romaine has to make sure we’re represented effectively in Suffolk County.

Even more troubling is the fact that the new county redistricting plans, which don’t go into effect until 2014, have already been finalized, so any hope that the district could be redrawn to better serve the North Fork is lost.

The current district lines have never made any sense, apart from the fact that they were drawn in a way that enabled Mr. Romaine to represent the East End all these years.

It seems more logical that Center Moriches share a district with Moriches and East Moriches than with Greenport. It also would appear to make more sense for Wading River and Shoreham to share a district than the current arrangement, which aligns Wading River with the likes of Peconic and matches Shoreham with Coram. While that latter scenario certainly rhymes, it is without reason since Wading River and Shoreham currently share a school district.

These district boundaries didn’t bother us so much last election, when they enabled Mr. Romaine to continue representing us in the Legislature, but the possibility of a change on the horizon highlights just how oddly the county jigsaw pieces fit.

Should Mr. Romaine move on to Brookhaven Town government, we hope whoever replaces him pays as much attention to the needs of residents on the North Fork as he or she does to those in Brookhaven.

Council district gerrymandering doesn’t hurt so much when you’re represented well, but our communities could be facing years of being overlooked and underserved if our next legislator’s focus leans toward another spot on the map.
